A kind of automobile nut plate extrusion molding die

Abstract

The invention discloses an automobile nut plate extrusion molding mold and relates to the technical field of automobile part processing tools. The automobile nut plate extrusion molding mold comprises a blanking-punching mold and a blank extrusion molding mold. The blanking-punching mold comprises a first pressing mold and a first bearing mold. The first bearing mold is provided with an extrusion platform and a retainer ring. The top surface of a central post aligns to the extrusion platform. The first pressing mold is provided with a blanking barrel. The blank extrusion molding mold comprises a second pressing mold and a second bearing mold. The second bearing mold is provided with a cavity. A molding module is arranged in the cavity. The second pressing mold is provided with a shore. The shape of the bottom surface of the shore matches with the shape of the top surface of the molding module. A mold hole is arranged between the top surface and the bottom surface of the molding module. An ejection core is arranged in the mold hole. The bottom surface of the shore is provided with a mold rod. The automobile nut plate extrusion molding mold utilizes a metal plastic-forming principle and realizes preparation of a product having a standard pattern from a blank material by punching and extrusion. The automobile nut plate extrusion molding mold has the advantages of simple processes, low rejection rate and reliable quality.

Description

technical field [0001] The invention relates to the technical field of processing tools for automobile parts. Background technique [0002] The nut plate is an important part on the sub-frame of the frame assembly in the series of European cars. The production of the nut plate belongs to the field of plastic processing of metal materials with high efficiency, high quality and low consumption. In the machinery manufacturing industry, the level of extrusion extrusion technology has become one of the important indicators for the continuous development and development of various enterprises. In a sense, the development level of extrusion technology is an important symbol of the national automobile industry level, the overall industrialization level, and even the modernization level.

AI Technical Summary

Problems solved by technology

[0003] At present, in the automobile manufacturing industry, the existing process of making automobile nut plates includes the process of using thin steel plates for multiple drawing and re-upsetting. The manufacturing process includes: blanking, seven times of rolling, punching, upsetting, repairing There are 12 processes while waiting, the disadvantage is that there are many processes, it is difficult to control the flow of materials, the rejection rate is high, and the quality is unstable

[0004] In order to overcome the shortcomings of the drawing process used in the production of the existing automobile nut plate, a new type of automobile nut plate extrusion molding die is needed
