Description

Mould inscription runner structure

Technical Field

The utility model relates to the technical field of injection molds, in particular to a mold inscribing pouring gate structure.

Background

The injection mold is a tool for producing plastic products and also a tool for endowing the plastic products with complete structures and precise dimensions. Injection molding is a process used in mass production of parts of complex shape. Specifically, the heated and melted plastic is injected into a die cavity under high pressure by an injection molding machine, and a formed product is obtained after cooling and solidification.

The conventional injection mold has the advantages that after the product is produced, the product is required to be ejected, but most of the molds need to automatically cut and separate the product from the pouring gate when the product is ejected, and manual pouring gate cutting is also required to be manually performed according to the conventional design, so that manpower is wasted and the production cost is increased when the conventional injection mold is manually operated, and therefore, the in-mold pouring gate cutting structure is proposed.
