Consideration of clamping force(RoHS Approved Manufacturer of manufacturing shop） The lateral clamping force of the mold is relatively small, so for large products with a large projected area, the direction with the large projected area should be placed in the opening and closing directions of the front and rear molds, and the side with a smaller projected area should be used as the side. To type.
Meet the product demoulding requirements The parting surface is for the product to be smoothly removed from the mold. Therefore, the position of the parting surface should be selected at the part with the largest section size of the product, which is a basic principle.

The shape of the parting surface For general products, a parting surface that is perpendicular to the direction of the mold opening movement of the injection molding machine is often used, and parting surfaces of other shapes are used in special cases. The shape of the parting surface is based on the principle of convenient processing and demoulding. Like a curved product, it must be based on its curved curvature when parting.
Ensure product appearance and quality The parting surface should not be selected on the smooth outer surface of the product. Generally speaking, the appearance surface is not allowed to have clip lines and other lines that affect the appearance; for some products with concentricity requirements, all parts with concentricity requirements must be placed on the same side, so as to ensure their concentricity.

Determination of orientation When determining the orientation of the product in the mold, the selection of the parting surface should try to prevent the product from forming side holes or side buckles, and should avoid the use of complex mold structures. 6, is conducive to demoulding The demolding mechanism of the general mold is in the moving mold, so when selecting the parting surface, the product should be left in the moving mold as much as possible after the mold is opened. Therefore, for some places that may stick to the fixed mold, we often add a fixed mold auxiliary demoulding mechanism. RoHS Approved Manufacturer of manufacturing shop
Consider the lateral mold opening distance The general lateral mechanical mold opening distance is relatively small. Therefore, when selecting the parting surface, the direction of the long core pulling distance should be selected in the direction of the opening and closing of the front and rear molds, and the short direction should be used as the lateral parting.
Mold parts are easy to process When selecting the parting surface, the mold should be divided into easy-to-machine parts to reduce the difficulty of machining. RoHS Approved Manufacturer of manufacturing shop
Conducive to exhaust When the parting surface is used as the main exhaust, the parting surface should be designed at the end of the plastic flow to facilitate exhaust.
R type For many products in mold design and parting, there is a full circle of R angle at the parting surface. At this time, the parting must take into account the best parting of R, and no sharp side should appear. RoHS Approved Manufacturer of manufacturing shop
