Slide block type device for powder spraying and wax injection

Abstract

The invention discloses a slide block type device for powder spraying and wax injection. The slide block type device for powder spraying and wax injection comprises a quantitative powder feeding part,a material injection part, a wax liquid injection nozzle and a vacuum interface, wherein the quantitative powder feeding part is used for quantitatively conveying powder for the material injection part, the material injection part comprises a feeding nozzle, a first air cylinder and a feeding sliding block, and the feeding nozzle is in sliding connection with the feeding sliding block; the wax liquid injection nozzle and the vacuum interface are connected with the feed sliding block; a first through hole and a second through hole are formed in the feeding sliding block; a material injection through hole is formed in the feeding nozzle; and under the drive of the first air cylinder, the first through hole communicates with the material injection through hole or the second through hole communicates with the material injection through hole. According to the slide block type device for powder spraying and wax injection, the first air cylinder drives the feeding sliding block to move to switch powder spraying and wax injection, so that the powder spraying and wax injection are integrally completed, and the working efficiency is greatly improved; and meanwhile, two baffle plates are arranged to realize quantitative conveying of powder under the drive of the air cylinders, so that powder spraying in a mould is uniform every time, the uneven manual powder spraying is prevented from influencing the forming of a wax mould, and the qualified rate of the wax mould forming is improved.

Description

technical field The invention relates to the technical field of wax injection equipment, in particular to a slider-type device for powder spraying and wax injection. Background technique In the prior art, the wax injection machine is an important basic equipment in the jewelry and handicraft industries. It is used to make wax models. First, the inside of the mold is evacuated, and then wax is injected into the mold. After the wax solidifies, the wax model is taken out. Before injecting the wax liquid, it is often necessary to spray powder into the cavity of the mold, and the powder spraying is often done by manually opening the mold first, and then spraying the powder, which is time-consuming, laborious, inefficient, and the amount of powder spraying cannot be controlled. As a result, the powder spraying in each mold is uneven, which affects the qualified rate of wax mold molding. Contents of the invention The purpose of the present invention is to overcome the above-men...
