A sleeve ejection mechanism and method of adjusting the same

By using the limiting block and spring of the sleeve-type ejection mechanism, the gradual ejection of the die casting is achieved, which solves the problem that the existing ejection mechanism cannot quickly adjust the ejection force, and improves the demolding efficiency and quality of the die casting.

AI Technical Summary

Technical Problem

Existing ejection mechanisms are difficult to adjust quickly according to different die castings, resulting in an inability to provide matching ejection forces for different types of die castings. Furthermore, the adjustment process requires the complete disassembly of the die casting mold, which affects production efficiency.

Method used

The sleeve-type ejection mechanism is adopted. By cooperating with the limit block and the spring, the preload of the spring is adjusted by adjusting the length of the limit block extending into the sleeve, thereby providing an ejection force that gradually increases from zero, which can adapt to different types of die castings.

Benefits of technology

It enables progressive ejection of different die-cast parts, reduces the impact load during demolding, lowers the probability of die-cast part damage, and improves production efficiency and demolding matching.

Abstract

本发明涉及压铸模具技术领域,具体涉及一种套筒式顶出机构及其调节方法。套筒式顶出机构包括推板、套筒以及顶出件。推板中部设有螺纹孔一,套筒固定安装于推板的上端;套筒内设有通孔一和通孔二。顶出件包括滑块、顶杆、限位块以及至少一对弹簧。滑块滑动安装于通孔二内。顶杆固定于滑块上端并伸出套筒外。每个弹簧的两端分别固接滑块和推板。限位块螺纹连接螺纹孔一并伸入通孔二内。通过调节限位块伸入通孔二内的长度来调节在限位块未接触滑块这一阶段中弹簧提供给顶杆的顶出力范围,进而匹配对不同类型的压铸件进行渐进顶出。通过旋转限位块的调节方式使得弹簧提供给顶杆的顶出力可进行无极调节,提高顶杆与不同压铸件之间的脱模匹配程度。
