根据弯钩浇口设置在定模的特殊情况，设计了一种组合式的加速顶出机构，详细阐述了该机构的结构组成及工作过程，对机构的关键技术参数进行了研究。试模证明：机构设计合理，可以实现塑件倒扣的抽芯和弯钩浇口的脱模。
根據彎鉤澆口設置在定模的特殊情況，設計瞭一種組閤式的加速頂齣機構，詳細闡述瞭該機構的結構組成及工作過程，對機構的關鍵技術參數進行瞭研究。試模證明：機構設計閤理，可以實現塑件倒釦的抽芯和彎鉤澆口的脫模。

A combined accelerated ejection mechanism was designed according to the state that the banana gate is set in the front mould. The structure composition and working prin-ciple of the mechanism were discussed; and the critical technology parameters of the mech-anism were theoretically studied. The experimental result shows that the mechanism can re-alize the core-pulling of up-side-down product and demoulding of banana gate.
