Injection molding process

The invention relates to an injection molding process and belongs to the technical field of injection molding. The method comprises the following steps: 1) filling a cavity with a molten material; (2) preliminary cooling is conducted, and the product is preliminarily cured; (3) one end of the product core serves as an inlet, the other end of the product core serves as an outlet, the inlet of the product core is inflated, and the uncured molten material of the product core flows out of the cavity through the outlet of the product core; 4, water is filled into an inlet of the core of the product, the water flows out of the cavity through the core of the product and an outlet of the core of the product, cooling of the product is accelerated, and final curing of the product is completed. 本申请涉及一种注塑工艺，属于注塑技术领域。其包括下述步骤：1）、在型腔内填充熔融的材料；2）、初步冷却，使产品初步固化；3）、产品芯部的一端作为进口，另一端作为出口，在产品芯部的进口充气，使产品芯部未固化的熔融材料通过产品芯部的出口流出型腔；4）、在产品芯部的进口充水，水经过产品芯部通过产品芯部的出口流出型腔，加速产品的冷却，产品完成最终的固化；5）、脱模得到最终产品。本申请具有更好的成型具有较厚部位的产品的效果。
