Description

Automatic gate cutting mold

Technical Field

The utility model relates to a runner mould field especially relates to automatic cutout runner mould.

Background

The mold used for plastic injection molding is called an injection mold; the injection mould can form plastic products with complex appearance, high size precision or with inserts in one step. For injection molding, the mold has a great influence on the quality of the molded product, and the gate, also called as a feed inlet, is a section of channel from the runner to the mold cavity and is the part with the smallest and shortest section in the pouring system. The gate is understood to be the last "gate" through which molten plastic enters the mold cavity through the runner system, and is the feed channel connecting the runner and the mold cavity. It has two functions: firstly, controlling the plastic melt to flow into a cavity; secondly, after the injection pressure is removed, the cavity is sealed, so that the plastic which is not cooled and solidified in the cavity cannot flow backwards. The gates can be divided into a straight gate, a side gate, a spot gate, a submarine gate, a lug gate and the like.
