How the mold becomes a product, the whole step of mold processing from design to product

If you are talking about a cold stamping die or a plastic mold, if it is a plastic mold, you must process the actual parts according to your design, and then assemble them and put them on the injection molding machine to make products. If you only need a few products, there are several ways.

First, you can make a sample mold, that is, use the old mold base, and how cheap the material is. Just make a cavity. Anyway, it's how cheap it is to make this mold.

Second, use machining to realize the shape of the product, and use turning, milling, drilling, CNC and other processing raw materials to directly do one by one.

3. Now there is a kind of rapid prototyping technology, which can be directly made with special equipment. Just like a 3D printer typing a drawing, it can be a bit expensive.

If it is a cold stamping die, it is easy to say that as long as there are a few products, if the shape is not complicated, it can be made through machining, electrical machining, and fitter operation to make a few products.

The mold is sent to the die casting factory to press the product.

Out of the rough do a little simple roughing.

The processed rough blank is polished.

The treated products are sent to the electroplating plant for plating.

Assemble the plating product into a complete product.

Wrap! This is the general process of die casting mold products.

What kind of material, plastic or aluminum die-casting, or hardware, to have a mold for the product, to the press as soon as you do it, there is a product.

For samples, it is recommended to do hand or casting.

There are a lot of external processing in the society, you can find someone to help you process, first of all, you must design the mold, then open the mold, and then to the machine to produce, plastic products are injection molding machines, hardware is punches, and now many manufacturers help people to play products.

The steps to make your own mold are as follows:

1. Prepare some small containers, some small lids, and iron boxes, as long as the bottom surface is flat.

2. Find the accessories you want to make the mold, the good choice is to have a flat part of the accessories, the full three-dimensional accessories are difficult to make the mold, it is difficult to succeed, so novices do not choose to do three-dimensional molds.

3.Prepare liquid silicone, it is easy to buy, the liquid silicone of the self-made mold is divided into AB glue, the ratio is 1:1, according to 1:

The ratio of 1 is to mix the liquid silica gel, and then stir evenly, the liquid silica gel is relatively viscous, it will be a little difficult to stir, you must have the patience to stir slowly, so that A glue and B glue are completely stirred.

4.After the liquid silicone is adjusted, put the accessories that need to be molded in a small box, and then slowly pour the adjusted glue into the box until the accessories are completely submerged, because the liquid silicone is very dense, sometimes the accessories are easy to float, so you must remember to press the small accessories to the bottom, if the mold is floated up, the mold will fail, so this must be checked.

5.After it is done, it is left to stand, generally 12 to 24 hours to dry, the small parts of the self-made mold are demolded, and the self-made mold is ready. It's very simple, let's share some small molds I made, which are very good.

Moldholder selection. Draw a group drawing.

2D or 3D demolition (mold kernel).

Material, metal material.

Standard size. Outsourcing processing.

Mold assembly. Cutting the table, preparing the materials, preparing the tools.

Frame mold, adjust the signal machine sample.

Send samples. Surface distribution.

1. Making a container:

One-piece mold double-spell mold, copying flat objects only needs a one-piece mold, copying three-dimensional objects need double-piece molds.

Please click Enter a description.

2.Measure the length, width and height of the object to determine the size of the container you need.

3.Containers are made based on the measured data. The material is optional, but the edges must be sealed, or the gaps must be filled with clay.

The container should be increased by centimeters in length, width and height of the object.

Cut out the four sides of the container and a square bottom from the foam board.

The panels must be glued with all-purpose glue and must be sealed.

2. Placing objects:

1.The production methods of one-piece molds and double-piece molds are somewhat different.

Clay should be used to make molds.

Twin mold: Spread clay in a container and insert the object vertically. The height of the clay reaches 1 2 points of the object, and the surface layer of clay is smoothed.

2.Follow the instructions to blend the molded rubber. There are many types of plastic mold rubber, and you should understand it before buying.

Latex ** is low and easy to operate, but the demoulding time is very long.

Silicone is durable.

3.Before molding, brush a thin layer of rubber on the surface of the object and carefully fill the gaps on the surface of the object.

4.Pour in the rubber, level with the mouth of the container, and cover the object sufficiently.

5.Follow the instructions to wait for enough time to demold.

3. Take out the mold:

One-piece mold: Break the container and remove the object from the mold. At this point, the mold is ready for use.

2.The other half of making a double mold:

Break open the container and take out the half-clay and half-rubber mold.

Carefully remove the clay, leaving the rubbery part.

Use a knife to carve 3-4 small triangular depressions in the rubber mold to be spliced as a joint with the other half of the mold.

A new container is made from an existing half of a rubber mold, which is twice as tall as the existing mold.

Put in half of the rubber mold, and then put in the object. Make sure that the container fits around the rubber mold.

Apply a layer of release agent to the surface of the half rubber mold to prevent the two mold halves from sticking.

Pour rubber into the container and allow it to solidify and demold. The double-spell mold is ready.

Mold is the mother of industry, is our daily life, meet and guarantee: daily necessities, electronics, five oak mountain bridge gold and other products can eventually be converted into physical products of the "mother", it can be said that without the mold, there is no these products, the specific mold can make the following products:

Home appliances: such as mobile phones, ** machines, washing machines, TV beams, etc. All kinds of plastic products and hardware products, such as: water cups, tableware, plastic boxes, plastic toys, computer cases, goldless brackets and hardware tools, as well as wires, connectors, sporting goods, baby bottles for babies and young children, as well as plastic insulators for hardware and electrical tools and lighting products.

Heat-resistant brackets, heat dissipation devices, each of us is a daily means of transportation.

The vast majority of cars, motorcycles, battery cars, etc. are made of plastic molds and metal stamping molds.

Metal powder forming molds and other molds are made and produced.

It can be said that each of us is inseparable from the mold in our daily life, and the "shadow" is that the mold constitutes our splendid and colorful life, bringing us a practical and comfortable product experience.

How the mold is produced, the precision processing process of the mold, after reading the insight.

The mold is actually very simple, first you have to understand the structure, secondly, you have to understand the material and its properties of the product, and finally you must know the relevant application software.

2: parting mold (mold cavity and mold auxiliary components, etc.) in the production of the appearance of the product at the same time, but also consider whether the smooth demoulding, etc., now another group of young engineers to design products are no slope. Maybe your mold design will not be able to produce the ideal product after it is designed.

Oh, that's probably the problem. Of course, there is also shrinkage, and the size of the cavity is larger than the size of the product, which you need to understand.

3: The 3D file of the mold drawing is directly transmitted for processing. Electrodes (sparks), inserts (wire cutting), cavities (CNC equipment production) and so on.

5: Debugging. There are many steps omitted in the middle, and if you can ask such a question, I am sure you also know the meaning of the mold itself, so I will not say much.

The mold design should do its own 3D drawing, and the relevant support letter documents of the mold manufacturing process should be done.

The mold is divided into medium mold, upper mold, and lower mold.

The most important thing is the mold core, what kind of mold core determines the mold, and the mold is pressed out by the main plastic machine.

The mold is made of things, saving a lot of labor. The carving is more expensive, and the labor cost is relatively high. The carved one becomes a work of art, and the mold can only be called a handicraft, which is definitely different. The mold is made of manual labor, and the carving is mental labor.

1.Digest the plastic parts diagram, understand the use of the parts, and analyze the technical requirements such as manufacturability and dimensional accuracy of the plastic parts. For example, what are the requirements for plastic parts in terms of appearance shape, color transparency, and use performance, whether the geometric structure, inclination, and inserts of plastic parts are reasonable, the allowable degree of molding defects such as welding marks and shrinkage holes, and whether there is post-processing such as coating, electroplating, gluing, and drilling.

Select the size with the highest dimensional accuracy of plastic parts for analysis to see if the estimated molding tolerance is lower than the tolerance of plastic parts, and whether the plastic parts that meet the requirements can be molded. In addition, it is necessary to understand the plasticizing and molding process parameters of plastics.

2.Digest the process data, and analyze whether the molding method, equipment model, material specifications, mold structure type and other requirements proposed in the process task book are appropriate and can be implemented.

The molding material should meet the strength requirements of plastic parts, and have good fluidity, uniformity, isotropy and thermal stability. Depending on the use of plastic parts, the molding material should meet the requirements of dyeing and metallization conditions, decorative properties, necessary elasticity and plasticity, transparency or reverse reflective properties, adhesive or weldability.

3.Determine the molding method.

Whether it is a direct pressure method, a casting pressure method or an injection method.
