Precautions for Designing Plastic Mold Pouring System

Plastic molds are tools used in the plastic processing industry to match plastic molding machines, giving plastic products a complete configuration and accurate dimensions. Due to the wide variety of plastic varieties and processing methods, as well as the complex and simple structures of plastic molding machines and plastic products, the types and structures of plastic molds in Dongying are also diverse. When using Dongying plastic molds, we sometimes encounter the situation of top white deformation. What is the reason for this?

1. The number of plastic mold push rods is insufficient or the diameter is too small, resulting in a single push rod bearing excessive pushing force.

2. The polishing of the plastic mold core is not enough, and the product has excessive clamping force on the convex mold.

3. The polishing direction of plastic molds is incorrect. Polishing must be done along the demolding direction, otherwise the clamping force will increase.

4. Plastic mold polishing or machining errors result in negative demolding slope of the convex mold.

5. The problem of adjusting plastic molds: if the injection pressure is too high and the holding time is too long, it will increase the clamping force of the product on the Dongying plastic mold.
