摘要:
目前,在进行电雷管（含数码电子雷管）脚线塞生产制造过程中，由于模具注塑料供料通道设计不合理等原因，导致部分通道余料残存于注塑制品上，且去除浇口废料费时费力。新型注射模结构在传统注塑模具中增加了堵孔部件，一次注塑完成后，堵孔杆下移，使注射料通道和模型腔内物料分离。生产实践证明，该新型注射模结构能够实现电雷管注塑产品表面无浇口废料，表面光洁并不需进行人工剔除，同时节约了注塑原辅材料。
Abstract:
During the production of wire plugs of electric detonator (including digital electric detonator), part of injecting channel remanet can be observed on the injection molding products due to the poor design of feeding channel in injection mold, which consumes time to remove the sprue wastes. Compared to the traditional injection mold, the new injection mold was introduced with increased plugging hole structure. Once an injection is completed, blocking rod comes down, and then materials in injection feeding channel is separated from the model cavity. It has been proved by production and practice that the new injection mold structure can realize zero-wastes on the surface of the injection molding products to avoid artificial culling because of the smooth surface. At the same time, raw materials for the injection are saved.
