摘　　要：针对PC+玻纤混合料熔点高、流动性能差的特点,通过对模具的改进,将原来的普通浇注系统改为热流道系统。解决了充模困难、缩水、气纹,夹水纹和产品合格率低等不良现象,并节约了原材料,提高了生产效率和产品质量。According to the mixture characteristics of PC and glass fiber such as high melting point and poor flowing property, the injection mold structure was improved, and the hot runner system was adopted instead of the original common gating system. The new design has sloved the difficulty in mold filling and the problems of shrinkage, gas strias, water strias, and low qualified rate of products. Meanwhile, it could save the raw materials, improve productivity and quality of products.
