Forming Technology of Car Window Triangular Plate with Bright Strip Decoration

Abstract

The invention discloses a forming technology for a window triangular plate with the bright strip decoration. The forming technology includes the steps that firstly, a forming die used for injection molding is manufactured; secondly, die assembly is conducted; thirdly, hard glue nozzle injection is conducted on a hard glue feeding port (3) of the forming die, cooling and pressure maintaining are conducted, and a semi-finished product is obtained; fourthly, a sliding block in a sliding block air cylinder assembly is extracted out so that an inverted buckle on a window triangular plate is released from the die; fifthly, die opening is conducted, meanwhile, an ejection mechanism ejects the semi-finished product, and the ejection mechanism resets after the semi-finished product is taken out; sixthly, the semi-finished product is put into a corresponding soft glue cavity (6), and meanwhile a metal bright strip (7) is attracted to an electromagnet (8); seventhly, die assembly is conducted again after the sliding block air cylinder assembly resets; and eighthly, soft and hard glue nozzle injection is conducted from a soft and hard glue feeding port, and a finished product is obtained after cooling and pressure maintaining are conducted. After the above technology is adopted, overall forming of soft glue, hard glue and the bright strip can be completed simply through one die, and therefore the production efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a molding process of a window triangle plate decorated with bright stripes. Background technique [0002] The window triangle is a small triangular plate located between the rear window of the car and the C-pillar, and the triangle body is the main part of the triangle. The triangular plate body is usually made of two materials, soft rubber and hard rubber. The process of encapsulation is adopted, that is, after the hardware product is finished, it is placed in another set of molds for injection molding software. After molding, the soft rubber is wrapped in it. The hard glue is on. In addition, many models are also decorated with bright strips at the position of the window triangle, and the bright strips are made of metal materials. It can be seen that the manufacturing process of the vehicle window square plate body made of these three materials in the prior art is v...

AI Technical Summary

Problems solved by technology

It can be seen that the manufacturing process of the vehicle window square plate body made of these three materials in the prior art is very complicated, and at least two pairs of molding dies will be used. Therefore, the disadvantages it brings are:

[0003] 1) There are many molds used in the manufacturing process, which greatly increases the production cost; at the same time, there are many processes, which greatly reduces the production efficiency;

[0004] 2) In the prior art, because the two sides of the bright strip are vertical surfaces, when the bright strip is directly formed in the mold, the place where the bright strip contacts with the soft glue is very easy to fall off, thus affecting the quality of the product;

[0005] 3) There are many undercuts and corners on the back and corners of the triangular plate body, so it is difficult to release the mold
