Description

Hafu dynamic template structure

Technical Field

The utility model relates to the technical field of molds, in particular to a Hafu mold movable template structure.

Background Art

Moulds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Harvest moulds refer to moulds that are divided into two halves and assembled together.

When taking out the finished product, the Hafu mold uses the push rod and push plate of the ejection mechanism to push out the product. The push rod is fixed on the push plate. When pushing out, the push rod drives the push plate to push out the product, and also drives the inclined slide rod to pull the core inside the Hafu block. Its characteristic is that the inclined slide rod also plays the role of a push rod to push out the gate solidified material.

However, the commonly used inclined sliding rod applies force to the side end of the product, resulting in that when the product is stripped, the force applied by the inclined sliding rod cannot be fully utilized, thus affecting the stripping speed.
