Do you know the injection molding industry on the first floor?

It is difficult for the mold master to find a job.

You can really pretend.

It's hard to find, if you're engaged in molds, you can also adjust the machine, it's hard to find.

I've been doing this for a few years. But now it's only about 3,000 in Jiangmen. I don't think it's too difficult to find a job. It's not easy.

It will take about three or five months to adjust the machine alone.

Injection molding machine is a typical electromechanical equipment, which is widely used and closely related to our daily necessities. Learning the adjustment of the injection molding machine is just a skill of the operator, learn it well. You can't rush your study time.

It depends on the learning environment. In a production of products are often subjected to, changing molds, materials, adjusting pressure, injection opening time and other operations are frequent, practice makes perfect.

You can also learn about the structure of the injection molding machine and improve your maintenance skills.

Injection molding machines are also known as injection molding machines or injection machines. It is the main molding equipment for making thermoplastics or thermosets into plastic products of various shapes using plastic molding molds. It is divided into vertical, horizontal, and all-electric type.

The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to be injected and fill the mold cavity.

If it's just to adjust the machine, be diligent and studious, about three or five months can be adjusted alone, in fact, it is very simple, as long as some important theoretical knowledge should be memorized, should be remembered, and should be understood, it will become, and the injection molding machine will be transferred back and forth There are only a few things.

Summary. 1. The action procedure of the injection molding machine: nozzle forward, injection, pressure holding, preplastic, retraction, nozzle retreat, cooling, mold opening, ejection, needle withdrawal, door opening, door closing, mold clamping, nozzle forward.

2. Injection molding machine operation items: Injection molding machine operation items include control keyboard operation, electrical control cabinet operation and hydraulic system operation. The selection of injection process action, feeding action, injection pressure, injection speed, and ejection type, the monitoring of temperature, current and voltage of each section of the barrel, and the adjustment of injection pressure and back pressure are carried out.

3. Injection process action selection: Generally, the injection molding machine can be operated manually, semi-automatically and fully automatically. Manual operation is in a production cycle, and every action is realized by the operator toggling the operation switch.

Generally, it is only used when testing the mold adjustment; When semi-automatic operation, the machine can automatically complete the action of a work cycle, but after the completion of each production cycle, the operator must open the safety door, remove the workpiece, and then close the safety door, so that the machine can continue the production of the next cycle; When fully automatic, the injection molding machine can automatically enter the next working cycle after completing the action of one working cycle. There is no need for downtime during normal continuous operation.

Make controls and adjustments.

Can anyone tell me how to set up an injection molding machine. What are the steps to adjust the machine, simply say thank you

Hello, if mine is helpful to you, please give a thumbs up.

Have a great day.

Injection molding technology is a very practical technology, which should be combined with theory and practice to make rapid progress.

Whether to learn the theory first and then practice, or practice for a period of time and then learn the theory, this is inconclusive, mainly depends on the personal opportunity. Generally speaking, learning theory and then practicing it is more directional, which can avoid blind guessing. And if you have a certain amount of practical experience and then learn the theory, it is easier to understand it by reading a book.

In any case, the study of theory is very important.

Injection mechanism part: mold locking system, mold adjustment system, ejection system, injection system, plasticizing system;

Injection mold: gating system, lateral parting core-pulling system, ejection system, temperature control system, mold base;

Injection molding raw materials: commonly used injection molding raw materials must be learned;

Injection molding process: the principle of injection molding, the influence of temperature, pressure, speed, position, time on the molding of injection molding process, the processing performance of polymers, the physical changes of polymer processing, etc.

Performance and testing of injection molding materials: this can be optional.

First understand the structure of the injection molding machine, the working principle of each part, the range of parameters and how to set and debug!

Understand the characteristics and specifications of commonly used plastics.

Find a teacher to pay to learn the process of frame mold and machine adjustment.

It is best to learn the principles of injection molding, the knowledge of mold structure (focusing on the influence of glue points, runners, exhaust, etc. on molding).

The first boss said what a cow! If you do what he says, then you are dead, and every point can cripple you.

If you really want to learn, buy a book dedicated to injection molding, it's all there. You can learn as you watch, and if you have a theory, you will have a little bit of a bottom in your heart.

Manual operation is used for dispatching and maintenance;

Semi-automatic operation is used for injection molding of fragile and easily scratched and long body products;

Fully automatic operation is used for high-speed production, injection molding of precision products, and can reduce operator workload.

Clamping part: 1. Install the mold.

a. Measure the thickness of the mold and estimate the maximum stroke of the mold ejector plate;

b. Measure the distance between the mold surface and the ejector plate;

c. Straighten the machine hinge with manual operation, that is, clamping;

d. Open the twist of the mold adjustment device, adjust the distance between the head plate and the movable template, until the distance is slightly thicker than the mold, and close the twist of the mold adjustment device;

e. Open the mold by manual operation until it is exhausted;

f. Manually operate the needle withdrawal until the hydraulic thimble is completely retracted;

g. Stop the machine and install the mold on the head plate;

h. Adjust all mold locking and mold opening speed and pressure to between 30-50% (not too high);

i. Start the machine and lock the mold, until the hinge is completely straightened; Stop the celebration section machine, and install one side of the mold on the movable template;

g. Turn on the machine, and use manual operation to set the movable template back a little to separate the mold;

k. Stop the machine, then tighten the fixing screws of the mold, start the machine to try the clamping, and adjust the speed and pressure of mold opening and clamping; l. Readjust the relevant travel switch and inductance block to make the action of mold opening and clamping smooth.

m. Stop, adjust the end position before touching the thimble, so that the thimble position cannot be longer than the maximum feasible stroke of the mold thimble. In general, the ejector pin stroke can be shortened to speed up production. In addition, the ejector pin speed should not be adjusted too high;

2. Adjustment of clamping force.

a. Open the mold by manual operation until it is exhausted. Start the mold adjustment device, adjust the mold thickness to generate the clamping force, and close the mold adjustment device to lock the mold guess. The reduction in mold thickness is directly proportional to the resulting clamping force.

However, if the mold thickness is reduced too much, the mold cannot be locked. It is recommended to reduce the mold thickness in a gradual manner.

B, the first step of the second reputation of the reputation, until the hinge and the formwork column (green column) produce sufficient clamping force. The working pressure of the clamping cylinder can be seen from the pressure gauge of the hydraulic system, and the thrust generated by the clamping cylinder is proportional to the working pressure in the cylinder, but due to the amplification through the hinge. The final clamping force is not proportional to the working pressure of the clamping cylinder.

However, in general, the higher the pressure, the greater the clamping force.

c. Generally, the clamping force can be adjusted to prevent the production of the front when the glue is shot, and the clamping force should not be adjusted too high, so as to avoid the deformation of the mold and the load of the machine hinge.

If you don't understand anything, just ask me.

1) Look more, there must be a master to learn to adjust the mold, watch more at the master's operation, and watch more at the operation of others.

2) Ask more, ask if you don't understand, the master is a little unique, and it is right to ask for more advice if you don't understand.

4) Use more brains, adjusting the machine is a technical job, which has the material properties, characteristics, melting point, baking time of the plastic are particular when adjusting the machine, you must be familiar with various materials, and you must also have an understanding of the mold, so that you can adjust the mold, come on!
