Novel automobile sealing strip extrusion machine head

Abstract

The invention belongs to the technical field of automobiles, and particularly relates to a novel automobile sealing strip extrusion machine head. The novel automobile sealing strip extrusion machine head comprises a machine head body, wherein a B mandrel is arranged on the machine head body; a D mandrel is fixedly connected to the inner side of the B mandrel; an A mandrel is arranged on the innerside of the D mandrel; the A mandrel is fixedly connected with the D mandrel; and a C mandrel is fixed to the inner side of the bottom end of the machine head body. The novel automobile sealing stripextrusion machine head combines composite extrusion functions of composite materials such as all kinds of steel bands, fiber lines, PE belts and EPDM rubber; four rubber extrusion machines can be synchronously operated to carry out the combined extrusion on different materials; a fifth kind of extrusion material can be added; differential temperature of different rubber materials can be controlledand protected, and the cooling is fully performed; and meanwhile, the rubber materials are forcibly divided into an annular distribution through one point in a special extrusion area in a flowing channel in the extrusion machine head and then are uniformed circled by 360 degrees to be pushed out; dead angle is avoided; circumstance of accumulating and scorching of the rubber are greatly avoided;and a good design foundation is supplied to the design of an extrusion die.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a novel automobile sealing strip extruder head. 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 extrus...

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
