How do you control the conditions of mold opening and injection molding?

Summary. In the production process, if the injection molding machine cannot open the mold, it may be caused by the following situations: 1

Excessive oil supply in the cylinder may affect the piston movement of the cylinder, resulting in the mold not being able to open normally. 2.The cylinder movement pressure is too small, which slows down the mold opening and closing action, and the mold opening is difficult to complete.

3.The failure of the motion control system of the injection molding machine will cause the mold to open and close abnormally, and the mold cannot be opened. 4.

The damage of the mold parts will make the force of the mold unbalanced, and the pressure distribution of the mold will be unbalanced, which will also lead to the failure of the mold to open the mold normally. Therefore, in order to solve the problem that the injection molding machine cannot open the mold, it is necessary to first check the working status of the mold, judge whether the cylinder movement pressure is not enough or the mold itself is faulty, and then repair and deal with it according to the situation.

Therefore, in order to solve the problem that the injection molding machine cannot open the spike mold, it is necessary to first check the working status of the mold, judge whether the cylinder movement pressure is not enough or the mold itself is faulty, and then repair and deal with it according to the situation.

I'm still a little confused, can you be more detailed?

It is very important to maintain the injection molding machine because it can effectively extend the service life of the machine. First of all, it is necessary to ensure that the injection molding machine is used correctly according to the circular fiber method on the manual, and regularly check the various components in the machine to ensure its normal operation and solve the problems found in time. Secondly, the air filter and lubricating oil need to be replaced regularly according to the use situation, and the tightness of the machine should be checked while lubricating the machine parts.

Finally, the injection molding machine is cleaned to prevent grease from contaminating the components inside the machine and to ensure its proper functioning.

In fact, the injection molding machine can't open the mold because the mold expands. Generally, the person who adjusts the machine is not adjusted well, the materials are full, and the mold is injected into it, which causes the mold to expand. Generally, the relative state of the transparent thin-walled mold will occur when it touches multiple points.

The injection molding machine can't open the mold, we first increase the mold opening force of the injection molding machine, and the mold opening force can not be opened, then we generally close the stove and put it on the larger injection molding machine to pull it away. For example, if you put it on a 500-gram injection molding machine, the injection molding machine can't pull it open. You put it on top of a 2 kg injection molding machine.

Another method is to remove the mold and use a steel brazing skil, which is the kind of large and long steel drill used in construction sites. There is a groove on the mold called the pry pit, and the mold can be opened by using a steel drill to pry the mold.

It may be that there is a problem with the mold clamping system, and you can check if there is any damage, air leakage, or other reasons that cause the mold to hold the mold is not enough. It may also be that the mechanical transmission is stuck, and you should check whether the movement of the motor, reducer and chain is normal. In addition, it may also be a failure of the hydraulic system, you can check to see if there is a leakage of the code beam, and at the same time check whether the pressure relief valve and the hydraulic cylinder sealing ring of the wheel mold are worn.
