A Die for Automobile Bumper that is Easy to Die

Abstract

The invention discloses an automobile bumper mould facilitating demoulding. The automobile bumper mould comprises a mould body, a forming mould cover, a knockout device and a demoulding seat, and both the bottoms of the two side ends of the forming mould cover are fixedly connected with sliding blocks; and the forming mould cover is internally provided with a cavity, and the knockout device is composed of a mould ejection block and tightening devices. According to the automobile bumper mould facilitating demoulding, the forming function is provided for the overall appearance of a bumper through the forming mould cover, and buffer plates are compressed downwards through the forming mould cover in a sliding structure in the mould punching process, so that the forming mould cover is moved downwards overall; meanwhile, tension is generated through one ends of the springs in the tightening devices, and the knockout device is moved downwards overall; since the downward movement is delayed, the primary mould ejection function is achieved at the moment of mould punching; when the springs are reset, and thrust force is generated, so that ejector pins on the top of the mould ejection block penetrate through slots in the appearance of the bumper, and the secondary mould ejection function is achieved; and the high efficiency demoulding function is achieved overall.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an automobile bumper mould, which is convenient for lowering the mould. Background technique [0002] The car bumper is a safety device that absorbs and slows down external impact and protects the front and rear of the car body. Many years ago, the front and rear bumpers of automobiles were stamped out of steel plates into channel steel, riveted or welded together with the frame longitudinal beams, and there was a large gap with the body, which looked very unattractive. In addition to maintaining the original protection function, the front and rear bumpers of today's cars also pursue harmony and unity with the car body shape, and pursue their own lightweight. The front and rear bumpers of cars are made of plastic, which are called plastic bumpers. The plastic bumper of a general car is composed of three parts: the outer panel, the buffer material and the beam. Wherein the outer...

Problems solved by technology

[0003] Due to the large volume and many lines of the bumper itself in the existing bumper mold, it is easy to cause some inconvenience in demoulding, resulting in a decrease in the efficiency of mold release

And in the process of releasing the mold, using a large force is easy to cause damage to the bumper, which reduces the quality of the product
