Problems solved by technology

[0002] Now the plastic products in the injection molding industry adopt the side-entry gate method. When the gate of the injection molding machine is pushed out a certain distance after the product is injected, the product and the gate material are stuck together, and the gate needs to be cut manually, but in the process of manually cutting the gate , there will be a situation where the product is cut too much, or the nozzle is not completely cut, so it will cause waste in production

Embodiment Construction

[0009] Such as figure 1 As shown, the present invention is a gate insert structure, a channel 1 is set on the cylinder, the gate end 2 where the channel is connected to the mold gate has a small opening, and the other end has a large opening.

[0010] During production, the present invention is connected between the gate of the injection molding machine and the processed product, at the junction of the processed product and the gate. After the product is injected, when the processed product and the gate of the injection molding machine are ejected, the present invention The structure of the gate insert does not move, and the processed product and the gate of the injection molding machine are ejected by the thimble. Since the thimble of the injection molding machine is next to the inlet end of the gate insert structure, when ejecting, the inlet end is cut off. , so as to achieve the function of automatically cutting off the nozzle of the processed product. The size of the open...

Abstract

The invention provides a sprue insert structure. A passage is arranged in a cylinder; the opening at the sprue entry end of the passage, which is connected with a die sprue, is small; and the opening at the other end of the passage is big. The invention has the advantages that the sprue insert structure can be automatically produced after technical improvement, so that the operation of manually repairing a water gap is reduced, manpower is reduced, automatic mass production is facilitated, waste is reduced, and the production cost of an enterprise is reduced.

Description

Technical field: [0001] The invention relates to the technical field of mold gate structures, in particular to a gate insert structure. Background technique: [0002] Now the plastic products in the injection molding industry adopt the side-entry gate method. When the gate of the injection molding machine is pushed out a certain distance after the product is injected, the product and the gate material are stuck together, and the gate needs to be cut manually, but in the process of manually cutting the gate , there will be a situation where the product is cut too much, or the nozzle is not completely cut, so it will cause waste in production. Invention content: [0003] In view of the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a gate insert structure that can conveniently and conveniently cut off the gate. [0004] To achieve the above object, the present invention proposes the following technical solutions: [0005] T...
