; if some die corners are not easy to open the exhaust groove, first When the appearance and accuracy of the product are affected, the mold should be appropriately changed to inlay processing. This will not only facilitate the processing of the exhaust groove, but sometimes also improve the original processing difficulty and facilitate maintenance. The biggest drawback of the overall structure in the mold structure design is poor exhaust. For the integral cavity and core, there are mainly these kinds of exhaust methods:    (1) use the cavity of the groove or insert installation location;     (2) use the side insert seam;     (3) partially made into a spiral shape; (4) Install a slotted slat core and open process holes in the longitudinal position;    (5) Plastic mould suppliers When the exhaust is extremely difficult, use the inlay structure, etc..Based on years of experience in injection mold design and product testing, this article briefly introduces several venting groove designs. For product molds with complex geometries, it is best to determine the opening of the vent slot after several mold trials. Whether the mold has undergone special surface treatment, such as titanium plating, carbon titanium nitride. If it exceeds the rated tonnage of the machine, it is easy to cause damage to the machine and mold.   8. Whether the machine tool mold base has worn out.   10. Whether the material has good lubrication when stamping. Try not to use standard molds to process non-standard shapes.  4. 6.   6.. Whether to choose a reasonable die clearance. The neutrality of the upper and lower turrets. So what are the factors that affect the service life of the mold? The following Shenzhen Plastic Mould Factory will give you a detailed analysis. Therefore, when stamping thicker sheets in large stations, it is necessary to use an appropriate formula to calculate the punching force. Reasonable use of adjusting gaskets.   1.  2. Plastic bottle mould Factory I hope you can improve the service life of the mold after reading it. The type and thickness of the material.  5.   7.Perhaps for users, increasing the service life of the mold can greatly reduce stamping costs.   9. Whether the oblique edge mold is used appropriately.  3, the structure of the mold. Calculation of punching force     If the punching hole is relatively large when punching thick plates, it is necessary to accurately calculate the required punching force
