What are the main points when choosing a parting surface?

The choice of the injection mold manufacturer in the selection of the parting surface will affect whether the injection molded parts remain in the movable mold cavity or in the fixed mold cavity after the mold is opened, which in turn affects whether the injection molded parts can be successfully demolded, and also affects Processability of the mold cavity. Whether there will be "flash" at the parting surface or whether the trace lines of the parting surface will affect the size, shape, wall thickness, mold structure, mold exhaust and film mold of the injection molded parts. Therefore, when selecting the parting surface, it is necessary to comprehensively consider various influencing factors, conditions and requirements, and select the parting surface reasonably.
Factors that injection mold manufacturers should consider when choosing parting surfaces:
1. Under normal circumstances, the injection molded parts should stay in the movable mold cavity, which is more convenient for the demoulding of the injection molded parts;
2. The obstruction of the "obstacle body" should be avoided to avoid movement interference, so as to facilitate the demoulding of the injection molded parts and the processing of the mold cavity;
3. It should be set in a position that is inconspicuous and easy to remove flash, burr and easy processing;
4. It should be set at a position other than the tangent point of arc R without depression and arc;
5. The setting of the gate location and its shape should be considered;
6. It is beneficial to the arrangement of the pouring system and the exhaust system;
7. Does not affect the size and accuracy of injection molded parts;
8. The performance and filling conditions of plastics should be considered;
9. The processability and efficiency of molding should be considered;
10. The structure of the mold is simple, easy to use and reliable.
