针对塑料制品部分结构在推件板成型时,一次推出不能使制品完全脱模的问题,以物镜压圈为例,设计了注塑模具。根据塑料冷却后收缩的特性,设计了弹簧式推出先复位机构,利用推出机构回程,实现了第二次推出。该机构结构简单,成本低,工作可靠。 Part of the structure of plastic products in the pusher plate molding, the introduction of a product can not be fully released from the issue of the lens pressure ring, for example, the design of the injection mold. According to the characteristics of plastic shrinkage after cooling, a spring-type push-out reset mechanism is designed and the push-back mechanism is used to achieve the second launch. The mechanism is simple in structure, low in cost and reliable in work.
