Description

Long mold insert bearing structure and injection mold

Technical Field

The utility model belongs to the field of injection molds, and particularly relates to a long insert supporting structure, and provides an injection mold with the long insert supporting structure.

Background

Lateral parting of the injection mold is typically accomplished using a slide. However, if the amount of slider insertion into the product is too large, the slider front end portion must form an elongated projection under certain requirements. Such elongated, convex structures are typically designed as a single insert for the purpose of saving machining material and facilitating machining. Insert is inserted into a designated position to effect the injection molding process.

However, when the mold is closed for injection molding, the longer insert is too suspended, and may generate tiny movement due to the injection pressure in the mold, so that the appearance of the injection molded product is subject to large-piece flash, and the product size has deviation and other problems.

The conventional solution is to increase the positioning of the insert as much as possible before insertion and after sliding in the mold. However, this method is limited by the shape of the product, and cannot change the shape of the insert inserted into the product portion or shorten the length thereof, so that the problem that the insert is pressed and jogged during injection molding cannot be fundamentally solved, and thus the problem of product defects cannot be fundamentally solved.

There is thus an urgent need for a technique that provides a good supporting effect for an elongated member, and the present application has been made in view of this.
