Investment Casting Shell Dewaxing Machine

Abstract

The invention relates to the technical field of investment casting, in particular to a de-waxing machine for an investment casting mould case. The de-waxing machine comprises an outer box body and aninner box body, wherein a filter screen is arranged in the inner box body; the filter screen is used for dividing a space inside the inner box body into a heating layer and a de-waxing layer; a bearing mould base is arranged on the top of the filter screen; a plurality of mounting hole groups which are arranged at equal distance are formed in the bearing mould base; four supporting blocks which are distributed in the form of a rectangle are arranged in the inner box body; a heater is arranged in the heating layer; a water inlet tube hole and a water outlet tube hole are separately formed in the two sides of the outer box body; a water draining assembly is arranged beside the outer box body; a box cover hinged with the outer box body is arranged on the outer box body; a dryer is arranged onthe box cover; a temperature control device is arranged on the outer wall of the outer box body; four supporting legs are arranged on the bottom of the outer box body; and the dryer, the water draining assembly and the heater are electrically connected with the temperature control device. The de-waxing machine can realize a checking and de-waxing step on a wax mould without labor power, and reduces labor and raw material loss, so that production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of investment pattern manufacturing, in particular to an investment casting mold shell dewaxing machine. Background technique [0002] Investment casting, also known as lost wax casting, includes processes such as pressing wax, repairing wax, forming trees, dipping slurry, melting wax, casting molten metal, and post-processing. Lost wax casting is to use wax to make wax models of parts to be cast, and then The wax mold is coated with mud, which is the clay mold. After the clay mold is dried, it is baked into a pottery mold. Once fired, the wax mold is completely melted and lost, and only the pottery mold is left. Generally, the sprue is left when the clay mold is made. Then pour the molten metal from the sprue, and after cooling, the required parts are made. The investment casting process is more complicated, and it is not easy to control, and the materials used and consumed are more expensive, so it is suit...

Problems solved by technology

[0003] At present, when the traditional equipment is used for the demoulding process of the wax model, the wax removal of the wax model is often not clean enough, and it is necessary to manually check the wax model again to manually remove the wax, and the existing equipment is difficult to remove the wax. Collect waste after wax removal, resulting in waste of raw materials, which increases costs
