Problems solved by technology

[0002] After the injection mold is finished injection molding, its waste and plastic parts will be connected together. In the prior art, workers will pry out the waste through copper rods, and because the waste is located above the cavity and the cavity insert, and is connected with the cavity and the cavity The inserts are close together, and the plastic part is located in the cavity. The two are blocked by the cavity and cannot be taken out at the same time. The two are connected by the waste between the gates of the cavity, so it is very laborious to pry the waste with a copper rod. Time-consuming, labor-intensive, low production efficiency, and easy to damage the mold

Abstract

The invention discloses a mechanism for snapping a pin-point gate through a stationary mold push plate for an injection mold, wherein the mechanism comprises an upper compound plate and a lower compound plate, a runner plate is connected below the upper compound plate, a mold cavity fixing plate is connected below the runner plate, a mold cavity plate is connected below the mold cavity fixing plate, a mold cavity embedding block is fixed between the mold cavity plate and the mold cavity fixing plate, a fixed distance guide post is arranged below the upper compound plate, a baffle is installed below the fixed distance guide post to be matched with the mold cavity plate, an upper thimble plate and a lower thimble plate are arranged between mold pins installed on the lower compound plate, a discharging push rod is installed between the upper thimble plate and the lower thimble plate, a punch hole is formed in the lower compound plate, an injector mandril passes through the punch hole to contact with the lower thimble plate, a plastic element is arranged between a mold core embedding block and the mold cavity embedding block fixed in the mold cavity fixing plate installed on a supporting plate, a discharging plate is arranged on the mold cavity fixing plate to be fixed with the discharging push rod, the mechanism is characterized in that a mold push plate and a stationary mold push plate fixing plate are arranged in a hollow cavity processed in the mold cavity plate, the disk-shaped large end of a fixed distance pull rod installed below the runner plate is in contact with the stationary mold push plate, a waste material mandril and a waste material jacking out a resetting rod are fixed in the stationary mold push plate fixing plate, and the waste material mandril is in contact with the waste material.

Description

technical field [0001] The invention relates to an injection mould, in particular to a gate mechanism at a breakpoint of the injection mould, which utilizes a push plate of a fixed mold. Background technique [0002] After the injection mold is finished injection molding, its waste and plastic parts will be connected together. In the prior art, workers will pry out the waste through copper rods, and because the waste is located above the cavity and the cavity insert, and is connected with the cavity and the cavity The inserts are close together, and the plastic part is located in the cavity. The two are blocked by the cavity and cannot be taken out at the same time. The two are connected by the waste between the gates of the cavity, so it is very laborious to pry the waste with a copper rod. Time-consuming, labor-intensive, low production efficiency, and easy to damage the mold. Contents of the invention [0003] The purpose of the present invention is to overcome the sho...
