Several issues to pay attention to when selecting the parting surface of plastic mold
Plastic mold is a tool for plastic processing industry and plastic molding machine, which gives plastic products a complete configuration and precise size. Because of the variety of plastics and processing methods, and the structures of plastic molding machines and plastic products are different, the types and structures of plastic molds are also diverse.
The structural elements to be considered in the design of plastic molds are parting surfaces, structural parts, mold accuracy, and pouring systems. among them. As long as the parting surface refers to the contact surface of the concave mold and the convex mold when the mold is closed. The choice of its location and form is affected by factors such as the shape and appearance of the product, wall thickness, molding method, post-processing technology, mold type and structure, demolding method, and molding machine structure. So, what problems do we need to pay attention to when selecting the parting surface?
1. The largest cross section of the outline dimension of the die casting should be selected so that the die casting can be smoothly taken out of the cavity.
2. The surface quality and appearance requirements of castings and the accuracy of size and shape should be guaranteed.
3. The parting surface should be conducive to exhaust and prevent overflow.
4. It should be easy to process the mold and simplify its structure.
