This paper introduces a mechanical trip,it could ba made use of Permanent Magnet Aero-generator when the generator happens short circuit fault.

In the design of the plastic mould, a latch_lock mechanism was designed to transfer the machine driving force from the moving half to the fixed half to make the ejection system of the fixed half work.

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.

The ejection mechanism design for the jack crust's injection mould;

The improvement of ejection mechanism design of YGP-2 injection mold;

Research and Realization on the Key Technology of Intellectualized Design System for Ejection Mechanism in Injection Mould;
