Device for improving sheet rushing during pouring

Abstract

The invention discloses a device for improving sheet rushing during pouring. The device comprises a first die and a second die. A first pouring groove is formed in the inner side of the first die, and a single-point heat nozzle is installed at the middle portion of the inner side of the first pouring groove. A pouring inlet is installed in the inner side of the first die and is located in the side portion of the first pouring groove. A second pouring groove is formed in the inner side of the second die and can be buckled with the first pouring groove. According to the device, the single-point heat nozzle is located at the middle portion of the inner side of the first pouring groove so that the area capable of being formed by the first pouring groove and the second pouring groove can be rapidly filled with injected raw materials conveniently; and the pouring inlet is located in the side portion of the first pouring groove so that the speed of filling the area capable of being formed by the second pouring groove and the first pouring groove with the raw materials can be further increased, and the raw materials can be prevented from being cooled midway.

Description

technical field [0001] The invention relates to a mould, more precisely a device for improving pouring and punching sheets. Background technique [0002] Many of the current display box products only need to be coated on the appearance surface, and there are structures related to assembly outside the coated area, and the structural area at the edge is relatively large. It is difficult to reach the coated area by hook-type pouring. The general method is to pour the edge of the product or use a three-plate mold to split the pouring point outside the film-covered area. In this way, the plastic cannot be directly injected on the sheet during injection molding, and the sheet is likely to be washed. The deviation even directly overturns the sheet. When the existing mold is cooperating and pouring, it is easy to cause leakage of raw materials due to its incompatibilities. Contents of the invention [0003] The object of the present invention is to provide an improved device for...

[0002] Many of the current display box products only need to be coated on the appearance surface, and there are structures related to assembly outside the coated area, and the structural area at the edge is relatively large. It is difficult to reach the coated area by hook-type pouring. The general method is to pour the edge of the product or use a three-plate mold to split the pouring point outside the film-covered area. In this way, the plastic cannot be directly injected on the sheet during injection molding, and the sheet is likely to be washed. Offset or even directly overturn the sheet

Existing molds are likely to cause raw material leakage due to lack of tight fit during pouring.
