Embodiment Construction

[0024] 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.

[0025] The application provides a discharge device, such as figure 1 and figure 2 As shown, it includes an upper template 1, a punch 2, a lower template 5, a lower mold insert 3, a limit screw 4, a spring 6 and a discharge insert 7.

[0026] The punch 2 is a rectangular steel plate, and is fixed on the lower surface of the lower formwork 1 by screw pins. The upper template is used to connect with the upper table of the machine tool, on which various parts of the upper mold are installed.

[0027] The lower template 5 is a rectangular steel plate, which is used to install the lower mold insert 3, and is fixed with the lower table of ...

Abstract

The invention relates to a discharging device comprising an upper template, a punch, a lower template, lower die inserts, limit screws, springs and discharging inserts. The punch is fixed on the uppertemplate. A groove is formed in the upper surface of the lower template. The lower die inserts are divided into a first lower die insert and a second lower die insert. The first lower die insert andthe second lower die insert are correspondingly fixed on the upper surface of the lower template on both sides of the groove. A guide groove is formed in side face of each lower die insert facing thegroove, and the discharging inserts, the springs and the limit screws are arranged in the guide groove. The discharging inserts are arranged in the lower die inserts, the discharging of the product completed in a mould is realized by the structure and action of the discharging inserts, and the quality of the product is ensured.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to an unloading device. Background technique [0002] Among the vehicle product parts, small stamping parts account for a large proportion, and reducing the mold cost of small stamping parts is related to the normal tooling development cost. [0003] In the prior art, for the stamping of U-shaped parts, the process part needs to be removed from the punch after the stamping is completed. In the prior art, the process part is dropped by adding an elastic device on the punch. The elastic device is usually a discharge bomb. For the ejector pin, when the stamping depth is large, the stroke of the ejector pin is relatively large, and it is easy to leave indentations on the product. Contents of the invention [0004] The object of the present invention is to provide an unloading device to solve the problems in the prior art that when unloading U-shaped parts, the stroke of the ejector pi...
