Embodiment approach

[0025] As an embodiment of the present invention, the support unit 2 includes a cylinder body 21, a movable plate 22 and a No. 1 column 23; the cylinder body 21 is fixedly installed on the base 11; the movable plate 22 is located in the cylinder body 21 , one end of the movable plate 22 is fixedly connected to the bottom of the cylinder body 21 through a spring, and the other end is fixedly connected to the No. 1 column 23; the No. 1 column 23 is fixedly connected to the bottom of the lower mold base 12; the middle part of the top column 31 has a No. 1 channel , and the No. 1 channel communicates with the cylinder body 21 through the hose; the gas in the movement of the movable plate 22 is blown from the No. 1 channel to the lower mold base 12, and the lower mold base 12 is cleaned; in the stamping of automobile sheet metal During the process, scraps left by stamping are often attached to the lower mold base 12. If these debris remain on the lower mold base 12, it will affect t...

Abstract

The invention belongs to the technical field of dies, and particularly relates to an automobile sheet metal stamping die comprising a bottom plate, a base, a lower die holder, an upper stamping die, atop plate, first cylinders, supporting units, material ejecting units, pushing units and a controller. The upper stamping die is fixedly connected to the top plate through the first cylinders. Racksare arranged at the two ends of the upper stamping die. The base is fixedly installed on the bottom plate. The lower die holder is fixedly connected to the bottom of the base through the supporting units. T-shaped holes are formed in the lower die holder. The material ejecting units are located in the T-shaped holes correspondingly. Each material ejecting unit comprises an ejecting column and a U-shaped support. Each pushing unit comprises a first gear, a swinging rod, a first rod, a T-shaped rod and a wedge block. According to the automobile sheet metal stamping die, by means of the movement,in the vertical direction, of the upper stamping die, the ejecting columns can move in the vertical direction; by means of movement of the ejecting columns, automobile sheet metal where stamping is completed is ejected out of the lower die holder; it is avoided that when the lower die holder is ejected as a whole, high-power power devices are borrowed; and multiple purposes are achieved through one source, and the manufacture cost of the stamping die is reduced.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to an automobile sheet metal stamping die. Background technique [0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material to cause separation or plastic deformation to obtain the required parts; the stamping die is an essential part of the stamping process. [0003] There is also a technical solution for automobile sheet metal stamping dies in the prior art. For example, a Chinese patent with application number 2018106552795 discloses a support and protection device for stamping die demoulding, including a bottom plate, which is installed on the bottom plate A lower mold, the lower mold has an inner cavity, and the inner cavity is provided with an ejector device and a supporting mechanism symmetrically hinged on both side walls of the inner cavity and used to protect the ejector device, and the ejector device includes A...
