AI Technical Summary

Technical Problem

When the mold is being demolded, the clamping force between the product and the side slide block causes the product positioning pin to break, making it impossible to demold smoothly.

Method used

An auxiliary ejection and demolding side slide mechanism is adopted, including a side slide and a guide rod. The guide rod is provided with a T-shaped inclined surface, and the side slide has a T-shaped inclined groove. The side slide contains a forming block and an ejector rod. The ejector rod is connected by a spring. The guide rod pushes the ejector rod to push the product out of the mold.

Benefits of technology

It achieves complete demolding of the product and the side slider, avoids breakage of the positioning pillars, has a simple and reasonable structure, and improves demolding efficiency.

Abstract

This utility model provides an auxiliary ejection and demolding side slider mechanism, including a side slider and a guide rod. The guide rod has a T-shaped inclined surface, and the side slider has a T-shaped inclined groove and a recess. A forming block is set in the recess, and the forming block has several stepped holes. An ejector rod is set in the stepped holes, and a spring is sleeved on the ejector rod. The end of the ejector rod facing the side slider slidably passes through the side slider and extends to the T-shaped inclined groove. Several clearance grooves are opened on the end face of the T-shaped inclined surface facing the T-shaped inclined groove. The end of the ejector rod is placed in the clearance groove. Specifically, when the mold is opened, the guide rod is pulled upward, which drives the side slider to move horizontally, so that the product in the side slider groove is loosened from the side wall of the groove. Then, the T-shaped inclined surface of the guide rod pushes the ejector rod to move towards one side of the groove, pushing the product in the groove to further demold. This avoids demolding by relying solely on the movement of the side slider. The ejector rod pushes the product so that the product is completely demolded from the side slider, avoiding the problem of the product's positioning post breaking.
