Ensure the appearance and quality of the product. Meet product demolding requirements.　　3, R parting For many products, there is a full circle of R angles at the parting surface. The parting surface is for the product to be removed from the mold smoothly. In special cases, the parting surface of other shapes is used. The selection of parting surface is also the first step of mold design. At this time, the parting must consider the best parting of R, and no sharp side should appear. So, generally speaking, what principles will be followed in the selection of wholesale cap mould Factory mold parting surfaces? 　　1. Conducive to exhaust.The shape of the parting surface is based on the principle of convenient processing and demolding. Do not choose the smooth outer surface of the parting surface. Mold parts are easy to process.　　

But for many side cores, or when it comes to the pillow position, when hitting or penetrating.　　10. It is affected by many factors such as product shape, appearance, wall thickness, dimensional accuracy, and number of mold cavities. ​​Consider the lateral mold opening distance The general lateral mechanical mold opening distance is relatively small. Therefore, for some places that may stick to the fixed mold, we often add a fixed mold auxiliary demoulding mechanism.　

The so-called parting surface is the surface where the mold is opened to take out the product. Like a certain curved product, the parting must be based on its curved curvature. Consideration of clamping force. 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 avoid using complex mold structures.
