一种扶手储物箱体注塑模具
摘要：
本发明公开了一种扶手储物箱体注塑模具，包括底座、下模以及上模，下模中设置有下型腔，下型腔中设置有型芯和下成型机构，上模中设置有上型腔，上型腔的外侧壁处设置有环形镶件，所述上型腔中设置有与下成型机构配合的上成型机构，上模的顶部设置有注塑管道；上型腔和下型腔配合形成注塑型腔，下成型机构与上成型机构配合用于成型铰接孔；模体中设置有排气管道系统和冷却管道系统。本发明通过设置上成型机构和下成型机构，使得能够直接将箱体上不需要通过抽芯操作直接将铰接孔注塑成型，这样使得模具中不需要设置抽芯机构，少了抽芯操作，每个箱体注塑成型至少节约了10秒钟以上，还减少了注塑报废品的产生。
摘要（英）：

The invention discloses a handrail storage box injection mold which comprises a base, a lower mold and an upper mold. A lower cavity is formed in the lower mold. A mold core and a lower molding mechanism are arranged in the lower cavity. An upper cavity is formed in the upper mold. The outer side wall of the upper cavity is provided with an annular mold insert. An upper molding mechanism matched with the lower molding mechanism is arranged in the upper cavity. The top of the upper mold is provided with an injection pipeline. The upper cavity and the lower cavity are matched to form an injection cavity. The lower molding mechanism and the upper molding mechanism are matched for forming a hinge hole. An exhaust pipeline system and a cooling pipeline system are arranged in a mold body. By arranging the upper molding mechanism and the lower molding mechanism, the hinge hole can be directly injected and molded without core pulling operation on a box body, no core pulling mechanism needs to be arranged in the mold, core pulling operation is omitted, the time spent for injection molding of each box is saved by 10 seconds or longer, and produced injection molding scraped products are reduced.
