Stamping dies for protective valve brackets with ejectors based on the principle of smooth lifting

Abstract

The invention discloses a punching die with an ejector for a protection valve support based on a smooth lifting principle. The punching die with the ejector for the protection valve support based on the smooth lifting principle structurally comprises a die body, a pressing shaft assembling port, an air pipe connector, a bottom cross rod and a die splitting handle, wherein the die splitting handleis arranged at the upper end of the left side of the die body through an embedding way, and the pressing shaft assembling port is formed in the top part of the die body, so that an integrated structure I formed. According to the punching die with the ejector for the protection valve support based on the smooth lifting principle provided by the invention, after the die splitting handle lifts a punching top plate, air pressure is guided through a distribution pipe, and at the moment, a disassembling mechanism drives a middle die and an upper die to carry out die splitting, so that a workpiece can be conveniently picked in the follow-up process; and a drive shaft piece drives according to air of the distribution pipe so as to enable a jacking mechanism to rotate, and the workpiece is supported and jacked, so that a side jacking effect is achieved, the workpiece is prevented from being directly impacted and damaged and is prevented from ejecting outside the die, and the damage in a large range is prevented.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a stamping die for a protective valve bracket with ejector material based on the principle of smooth lifting. Background technique [0002] The protection valve is also called the four-way protection valve, the full name is the four-circuit protection valve. Under normal circumstances, the four-circuit protection valve is actually a five-way joint. It only plays a protective role when a certain circuit fails. It is mainly used in multiple circuits of automobiles. In the air brake system of the current gas brake system, due to the polymorphism of the protection valve, a three-layer stamping die is generally used in the stamping process, so as to ensure one-time molding. It is more troublesome to take the material, and it is impossible to part the mold at one time. There are such problems in the use of existing technologies on the market: [0003] The current stamping die adopts the direct ...

AI Technical Summary

Problems solved by technology

[0003] The current stamping die adopts the direct push method at the bottom. Although this can quickly part the mold, it also causes impact on the bottom of the workpiece, resulting in certain wear and tear, and it is easy to eject the workpiece out of the mold, causing a wider range of damage. optimization
