I am now working as a designer in a professional mold factory.

The division of labor of mold design in many companies is different, we do it more carefully, and require designers to do it more comprehensively, the following are some steps before we do design and design:

1) The customer sent the product 3D picture file (we generally do electronic products, mobile phones, printers, camera shells, plastic parts on the car, etc.), after getting the 3D, we began to review and put forward the plan, do the matching information, need to put forward the glue feeding plan, parting line, thimble position, insert line, row clamp line, inclined top clamp line, etc.; Some parts of the product are easy to shrink to reduce glue, easy to produce a front to reduce glue to prevent shortage, some places are difficult to fill the mold to propose glue, in short, this step is extremely critical, involving the actual problems and production problems that will occur when parting the mold in the future, etc.

2) Send the information to the customer to confirm that OK, we will start to draw the structure diagram, confirm the ranking of the product, how to transport the water, and there are some complicated structures to draw, such as the front and rear molds are pumped first, the row is inclined to the top, and the front mold is ejected. After drawing and confirming OK to the customer, we will start to order the mold base and inner mold steel. We use CAD to draw the structure of the factory

3) After that, it is 3D parting, in fact, when you parting line, reduce the glue short, the insert line is confirmed, plus the structural drawing is also finished, so that the drawing of 3D is very fast, do not have to think, as long as the product does not have too much curved surface structure and not too many exhaust inserts to be disassembled, the step of parting is the fastest, of course, you should also pay attention to a lot of small details that will only be encountered when the actual operation of 3D parting.

4) After that, it's time to draw the scalar number of the parts, yes, we don't have draftsmen, and the hard-working designers have to be responsible for all the parts drawings.

5) After the picture is finished, it is the purchase of accessories, such as spring thimble pull rod or something.

In fact, in many places, the parting steps are different, like Foxconn, they should be very detailed, some people do the matching data, some people divide the mold, and then the draftsman is responsible for the scaling of the following figure.

1. How to design: The mold designer must first understand the product requirements after molding, so as to tailor it, from material selection to all aspects of the structure. A good designer must have seen the actual structure of the real mold and the feedback solution for injection molding production.

Integrate it into his own design, so that the mold he designs will have few problems.

2. The software draws the mold drawing, which is indeed the job of the mold designer. But it can't be said that it is finished, because the processing master will process and make the mold according to your design drawing, whether it is the processing process, or the follow-up mass production will find you.

Mold design is to make the 3D drawing on the computer with iron, the process: the customer provides **, or a figure, or may be a 2D drawing, in short, the data provided by the customer to design the mold, and then send it to the customer for confirmation, and finally to the mold master drawings. Finish.

The later mold modification depends on the customer.

Mold design is not difficult, a set of complex molds is not out of thin air, there are basic routines and structures, so in general, the structure of similar molds is roughly figured out, but part of the part structure is unique, do you understand the routine! Don't think it's complicated, the vast majority of designs are based on their inherent rules of routine.

Software is just a tool for making pictures. It is not good to do without actual production experience and relevant knowledge training.

If you use ug, you must first build the things you want to do, and then build the mold base, analyze the ejection method, parting surface, see what special structure is needed, design the slider, inclined top and other things, and then produce drawings, mold assembly drawings, parts drawings, and then. Just pass on the drawings and UG files to the people who need them.

It depends on your specific topic, and you will be given a general stamping die design.

First, the analysis of parts and materials.

08F steel has very low strength and hardness, but has high plasticity and toughness, has good cold deformation and weldability, and the machinability after normalizing is acceptable, the magnetic permeability after annealing is high, and the remanence is less, but the hardenability and hardenability are extremely low.

2. Structural analysis of parts.

The structure of the part is simple, there is no tolerance requirement for the size, the size is free tolerance, and the shape is symmetrical.

3. Manufacturability analysis of parts.

The part is made of steel, the basic characteristics of the shape of the part are the general cylindrical parts with concave circles, there is a 10 holes at the bottom of the cylindrical parts, the internal circumferential diameter is 28, and the dimensions are free tolerances, because in general, the dimensional accuracy of the deep-drawn parts should be below the IT13 level, and should not be higher than the IT11 level. So change the inner diameter to 28+. The height of 10+ is IT11-IT12 level accuracy.

The main forming methods are punching, drawing, trimming, punching, and bending. The dt d and h d of the parts are not too large, and their drawing process is good. The part is produced in large quantities, and the shape of the part is simple and symmetrical.

The material is 08F steel, which is economical to use stamping.
