Problems solved by technology

[0003] What the present invention aims to solve is that due to the fact that there are few glue inlets in the automobile mold and the distance between the glue inlets is far away, the plastics will have a long converging distance and a small converging angle during the filling process, resulting in product welding. There are obvious marks and the product is easy to break

Abstract

The invention discloses a pitched roof shunt mechanism. The pitched roof shunt mechanism mainly comprises a hot runner nozzle, a main sprue, a shunt channel, glue inlets, a pitched roof block, a pitched roof copper sleeve, a pitched roof rod, a pressing block and a pitched roof base, wherein the top of the main sprue is connected with the hot runner nozzle, and the root of the main sprue is connected with the shunt channel; the tops of the glue inlets are connected with a product; the main sprue, the shunt channel and the glue inlets are all arranged inside the pitched roof block; the top of the pitched roof rod is connected with the pitched roof block, the bottom of the pitched roof rod is connected with the pitched roof base, and the ejection track of the pitched roof rod is controlled by the pitched roof copper sleeve and the pitched roof base; and the pitched roof copper sleeve is fixed with the pressing block.

Description

technical field [0001] The invention relates to the manufacturing technology of automobile exterior accessories, in particular to the manufacturing technology of molds applied to grids or one-mold multi-cavity products. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the quality of automobiles. In order to adapt to the development of the times and the needs of consumers, automobile manufacturers around the world are also constantly innovating. For example, grille products are all appearance parts and have strength requirements. Generally, multi-point heat flow is used in the mold. Road system, which greatly increases the cost of mold manufacturing. Due to the small number of injection points of the automobile mold and the long distance between each injection port, the plastics will have a long convergence distance and a small convergence angle during the filling process, resulting in obvious weld ...
