Description

Technical Field

[0001] The utility model relates to the technical field of mold ejection, in particular to a mold ejection mechanism with a protective function. Background Art

[0002] After use, the mold is at a high temperature, so workers may be burned by the product when taking out the molded product.

[0003] Usually after the mold is injected, it needs to be demolded for secondary injection molding, and the ejector mechanism is usually the most commonly used mechanism for mold demolding, such as a demolding ejector mechanism with the publication number "CN204413118U", which uses an external power mechanism to push the top plate through the through hole, thereby pushing the molded workpiece out of the groove. As an auxiliary function, the external power mechanism also pushes the molded workpiece out of the groove through the second through hole, but the device still has the following shortcomings when used;

[0004] The device pushes the molded workpiece out of the groove through the second through hole, but the device can only simply demould the molded workpiece. The workpiece after demoulding is usually at a high temperature, and the temperature has not been completely cooled down, which may cause burns to the staff, making the device a safety hazard when removing the workpiece.

[0005] Therefore, we proposed a mold ejection mechanism with protective function that can solve the above problems well. Utility Model Content
