The progressive demoulding mechanism and the working process of the injection mould were mainly introduced.

The key issues in the design of the hot runner system,the structure and movement principle of sequential demoulding mechanism were introduced in details.

Development of demolding mechanism for plastic part with internal thread;

A reliable but simple structure demolding mechanism of injection mould for helical wheel was introduced.

The structure characteristic of plastic slant lid is analyzed,the integer structure and main design points of the injection mold are introduced, the all-round demoulding mechanism is designed, in which the feeding system can fall off automatically and second ejector mechanism is designed.

Demoulding mechanism of taper thread and arc side core-pulling mechanism was used in the mold, and the design process of other make up,and working process of the mould are specified in detail.

By adopting pin point gate,reasonable demoulding mechanism and slow-feeding linear cutting,both size and position accuracy of the product were improved,guaranteeing its working stability and satisfying its technical requirement.
