对相配合的两件带螺纹且外形均为非轴对称的注塑件(如瓶盖和瓶体)分别进行了模具设计，在瓶盖注塑模具设计中，采用了可编程序控制器(PLC)作为主要的控制螺纹起始点位置的机电部件，采用光电传感器作为辅助部件，通过PLC的累加程序和输出电路，将PLC接入注塑机的液压顶出控制电路中，从而实现了瓶盖螺纹型芯在每次注塑完成后其螺纹起始点位置均保持一致的目的；在瓶体注塑模具设计中，通过对瓶盖模具PLC程序的改变，实现了瓶体螺纹型芯在每次注塑完成后其螺纹起始点转动一个规定角度的目的。通过以上设计，使得瓶盖和瓶体在装配后实现了规定的多样性特殊装配外观效果。

Mold design of two matching injection molding parts such as bottle cap and bottle with thread and nonaxisymmetric outer shapes was done respectively. In the mold design of bottle cap,PLC was used as the main electromechanical component for controlling thread start point position,and the photoelectric sensor was used as the auxiliary one,through the PLC accumulative procedure and the output circuit,the PLC was linked into the ejecting control circuit of the ejection machine,so the purpose is realized that the thread start point of the bottle cap thread core remains unchanged after completing each injection molding. In the mold design of bottle,through changing the PLC procedure of the bottle cap mold,the purpose is realized that the thread start point of the bottle rotates a specified angle after completing each injection molding. With these designs stated above,a specified various special assembly appearance effect is realized after assembling the bottle cap and bottle.
