Embodiment Construction

[0019] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0020] Such as figure 2 and image 3 As shown, a plastic mold structure molding process, including the first process is a blanking punching process; the second process is a flanging process; the third process is a flanging forming process; the fourth process is a shaping process;

[0021] This technical solution mainly changes and optimizes the above-mentioned structure and the mold structure similar to the above-mentioned shaping method and the feeding and feeding method of the part. The main purpose is to change the rebound shaping of this part from the side wall force to rotate the part by 90° After that, it is placed in the mold ...

Abstract

The invention relates to a structure molding process by utilizing shaping dies. The structure molding process comprises a first step of blanking and punching, a second step of flanging, a third step of flanging molding, and a fourth step of shaping, wherein the shaping step is carried out after the third step of flanging molding is finished, and comprises rotating a part by 90 degrees and then putting the part in the die, and shaping the part through lamination by using the molded surfaces of upper and lower dies; the part is fetched and put in such a manner of being parallel to the molded surface of the lower die. The direction of stress on the part is consistent with the direction of gravity; the part is easy to laminate and the effect of eliminating the resilience of the part is good; from the point of safety and operability, the part is quite convenient to fetch from the side surface.

Description

technical field [0001] The invention belongs to the field of automobile die stamping, and specifically refers to a die structure forming process for shaping. Background technique [0002] With the increase in the number of cars in the current market, the speed of the vehicle increases, and the number of accidents increases. Automobile safety is becoming more and more important, and one of the most obvious important measures is that automobile components should be significantly enhanced. [0003] Energy shortages and serious pollution are bound to require cars to reduce fuel consumption and save energy. An important way to reduce fuel consumption is to reduce the weight of the car. The latest research on the relationship between fuel consumption and weight of cars shows that: the fuel consumption of cars is linearly related to their own weight. If other conditions remain unchanged, it can reduce the fuel consumption of the car by at least 5%. [0004] How to reduce the weig...
