Automatic molding equipment for valve investment casting

Abstract

The invention discloses automatic molding equipment for valve investment casting. The equipment comprises a base, wherein a vibration device is fixedly connected to the top of the base, a rotating groove is formed in the middle of the base, and a rotating disc is rotatably connected to the interior of the rotating groove. According to the equipment, water is conveyed to the interior of a water containing tank by means of a water inlet pipe, the water in the water containing tank is enabled to flow out by means of a water outlet pipe, a metal solution of a mold body is rapidly cooled, the mold body passes through a lantern ring and slides into a containing hole, after the metal solution is poured into the mold body, a first motor rotates to drive a rotating disc to do reciprocating motion, the metal solution in the mold body shakes in a reciprocating mode, the yield of parts is increased, the metal solution is enabled to fill the mold body as much as possible, the mold body is cooled by means of the water in the water containing tank, the metal solution in the mold body can be cooled fastest conveniently, the mold body is moved by means of a hydraulic cylinder and a second motor, and the mold body is clamped out of the lantern ring by means of a clamp.

Description

technical field [0001] The invention relates to the technical field of investment casting equipment for valves, in particular to an automatic molding equipment for investment casting of valves. Background technique [0002] Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax repairing, tree formation, dipping, melting wax, casting molten metal and post-processing. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then coat the wax mold with mud, which is the mud mold. After the clay mold dries, it is placed in hot water to melt the inner wax mold. Take out the clay mold that has melted the wax mold and bake it into a pottery mold. Once roasted. Generally, when the mud mold is made, the sprue is left, and then the molten metal is poured into the sprue, and after cooling, the required parts are made. However, when the existing device pours the molten metal into the sprue, only Through the self-flow of...

Problems solved by technology

Generally, when the mud mold is made, the sprue is left, and then the molten metal is poured into the sprue, and after cooling, the required parts are made. However, when the existing device pours the molten metal into the sprue, only Through the self-flow of the metal solution into the clay mold, the metal solution cannot completely fill the inside of the clay mold, resulting in incomplete parts
