Extrusion head for automobile sealing strip

Abstract

The invention belongs to the technical field of automobiles, and in particular relates to an extrusion head for automobile sealing strips, including a head body, a mandrel B is arranged on the head body, and a mandrel D is fixedly connected to the inner side of the B mandrel. The inner side of the D mandrel is provided with an A mandrel, and the A mandrel is fixedly connected with the D mandrel, and the C mandrel is fixed on the inner side of the bottom end of the machine head body; , PE belt and other composite materials and EPDM rubber compound extrusion function, can use four rubber extruders to compound rubber materials of different materials at the same time, and can also add a fifth extrusion material, which has the ability to process different rubber materials The difference is temperature control protection, sufficient cooling, and at the same time, in the extruder head, through the specific extrusion area in the flow channel, the flow is forced to divide into a ring distribution, and 360 degrees are evenly pushed out in a ring, without dead ends, and it is not easy to produce rubber accumulation. The scorch situation provides a good design basis for the design of extrusion dies.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an extrusion head for automobile sealing strips. Background technique [0002] Sealing strip is a product that seals something so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, fixing, etc. Sealing strips are made of rubber, paper, metal, plastic Since the 1980s, sealing strips have been applied to various industries such as automobiles, refrigerators, and containers. According to the requirements of different industries, unique automotive sealing strips, mechanical sealing strips, door and window sealing strips, etc. have been developed. , Shanghai Jiaxie Precision Mold Co., Ltd. was established in 2010. It is a private enterprise that designs, manufactures and develops tooling molds for the automotive seal industry. These development and design work are all completed on the extru...

AI Technical Summary

Problems solved by technology

[0004] 1. In the process of using the original automobile sealing strip extrusion head, there are still some deficiencies. In the production process of the current automobile sealing strip extrusion head, a single rubber extruder can only extrude a single type Rubber products cannot satisfy the compound extrusion of multiple materials, and the production function is relatively single, which reduces production efficiency;

[0005] 2. The original automobile sealing strip extrusion head has a low degree of intelligence, and cannot carry out different temperature control and protection for the extrusion of different rubber materials. The cooling is not sufficient, and there are dead angles, which cause the rubber to easily scorch;

[0006] 3. The extrusion speed of the rubber material in the current automobile sealing strip extrusion head is slow, the rubber material is easy to accumulate, and the rubber material is not fully utilized, resulting in waste of rubber material and increasing production costs
