Stock bin discharging port shutoff valve for powder filling isostatic pressing forming die

Abstract

The invention discloses a stock bin discharging port shutoff valve for a powder filling isostatic pressing forming die. The stock bin discharging port shutoff valve comprises a stock bin and a shutoff valve body, the shutoff valve body comprises a valve body, a locking switch, a valve element and a driving part, the valve body is connected to a discharging port of the stock bin through the locking switch, the valve element is rotationally arranged in the valve body through the driving part, a valve body discharging baffle and a valve body discharging port are arranged at the bottom of the valve body, a cavity communicated with the discharging port of the stock bin is formed in the valve element, a valve element discharging baffle and a valve element discharging port are arranged at the bottom of the cavity, and the valve element can close or open the valve body discharging port through the valve element discharging baffle under driving of the driving component. The stock bin discharging port shutoff valve for the powder filling isostatic pressing forming die effectively solves the problems of dust raising, excess material overflowing, high labor intensity and the like in the traditional manual loading process, and the automation degree and occupational health level of isostatic pressing loading operation are remarkably increased.

Description

technical field [0001] The invention relates to the field of automatic charging of powder materials, in particular to a cut-off valve at the discharge port of a material bin used for powder material filling of an isostatic pressing molding die. Background technique [0002] Isostatic pressing has unique advantages such as high and uniform product density. The basic principle is that the powder in a flexible mold such as rubber or plastic is subjected to isotropic liquid medium pressure, so that the powder is pressed into a product with a certain density and strength. Dense body. [0003] Filling the mold with powder is the first step in isostatic pressing. At present, it is basically a manual operation, which relies heavily on personal experience. The labor intensity is high and the working environment is harsh, which brings great harm to the occupational health of the operators. In order to ensure that the powder filling inside the mold is even and full, it is necessary to...

Problems solved by technology

However, when the mold is removed after loading, the remaining material in the silo is easy to overflow and leak, which not only causes the inevitable consumption and waste of powder, but also virtually increases the operation process of cleaning up the spilled powder
