Description

Injection molding device with slider pushes up mechanism to one side

Technical Field

The utility model relates to an injection moulding device particularly, relates to an injection moulding device with slider pushes up mechanism to one side.

Background

The sliding block device is widely applied to plastic injection molds. Generally, a slide block of the slide block device makes a linear reciprocating motion along a direction perpendicular to a mold opening direction of a mold under the action of an inclined guide edge so as to complete actions such as side core pulling on a product. After the injection molding machine is used for injecting the plastic, after pressure maintaining and cooling are completed, the sliding block of the sliding block device synchronously moves linearly in the direction far away from the product while the movable mold and the fixed mold are opened.

When an injection molding product is produced, the side face of the product is often subjected to the phenomenon of back-off, and the direction of the back-off is inconsistent with the exit direction of the sliding block, so that the product needs to be demoulded by arranging an inclined top sliding block structure on the demoulding mechanism. The pitched roof is easy to position and is not firm when the existing pitched roof sliding block structure is used for injection molding, and retreating occurs, so that the problem of product forming is caused.
