One-way valve type powder spraying and wax injecting integrated type structure

Abstract

The invention discloses a one-way valve type powder spraying and wax injecting integrated type structure. The one-way valve type powder spraying and wax injecting integrated type structure comprises ascrew powder feeding device and a spray nozzle composite device; the screw powder feeding device is used for quantitatively conveying powder for the spray nozzle composite device which comprises a feeding spray nozzle head and a heat generating barrel; the feeding spray nozzle head is provided with a first through hole, and the heat generating barrel is arranged on the feeding spray nozzle head which is provided with a feeding port and a second through hole; the feeding spray nozzle head is provided with five powder outflow holes which correspondingly communicate with the feeding port; the second through hole further communicates with the powder outflow holes; the feeding port communicates with the screw powder feeding device; the first through hole is connected with a wax liquid pipe one-way valve; and the second through hole is connected with a vacuum pipe one-way valve. According to the one-way valve type powder spraying and wax injecting integrated type structure, due to the factthat the powder feeding work procedure and the wax injecting work procedure are integrated, manual powder spraying operation is not needed, and the work efficiency is improved; the powder spirally moves, quantitative conveying of the powder is completed in combination with the opening and closed states of an electromagnetic vacuum check valve, the efficiency is high, powder spraying in a mold is uniform, and the qualification rate of wax mold forming is increased.

Description

technical field [0001] The invention relates to the technical field of wax injection equipment, in particular to an integrated structure of one-way valve powder spraying and wax injection. Background technique [0002] 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 [0003] The object of the present...
