The principle of the opening stroke position of the injection molding machine

The opening stroke position of the injection molding machine refers to the movement distance required for the mold cavity to change from a closed state to an open state during the injection molding process. Its setting should take into account the structure of the mold, product size, pressure and speed and other factors to ensure the quality of injection products. The correct setting of the opening stroke position of the injection molding machine is the key to ensure the quality of the injection molding product.

The specific methods are as follows:

1.according to the product requirements and mold structure to calculate the appropriate location of the mold stroke.

2.set the injection molding machine to manual state, and add the injection plastic to the cylinder, and then install the mold on the injection molding machine.

3.Manually operate the injection molding machine and gradually open the mold until the opening stroke position is set in place.

4.automatic testing of injection molding machine to ensure that the mold opening position is correct and product quality meets the requirements.

common problems and solutions

1, mold stroke is too large or too small resulting in abnormal product size.

Solution: re-adjust the position of the opening die stroke of the injection molding machine to ensure accuracy.

2, mold opening stroke speed is too fast to cause mold damage.

Solution: Adjust the die stroke speed to reduce the risk of mold damage.

3,Improper setting of mold stroke position leads to defects on product surface.

Solution: Reset the opening stroke position to avoid the appearance of product surface defects.

summary

By correctly setting the opening stroke position of the injection molding machine, the quality of the injection molding product can be improved, problems such as defects and abnormal size can be avoided, and production efficiency and production efficiency can be improved. Therefore, the correct setting of the opening stroke position of the injection molding machine is a very important work, which needs to be taken seriously by the injection molding workers to avoid affecting the work effect.
