Abstract: It analyzed the positioning requirements and forming process of the screw cap, and expounded the working principle of the real-time adjustable mechanism at the start position of the screw and the screw rotational demoulding mechanism. The modular gear positioning mechanism was added in the screw rotational demoulding gear combination, so as to realize the real-time adjustable of the screw with start position on the injection machine. The practice showed that the mould structure design was reasonable and the work stably, which could provide reference for the similar screw positioning structure.
