Soaking type casting wax mold automatic wax melting device

Abstract

The invention discloses a soaking type casting wax mold automatic wax melting device. The automatic wax melting device comprises a channel steel base, a gantry, a cylinder, a cover plate, a connecting rod, a charging basket, a wax melting tank, a heating mechanism, an air injection pipe, a guide rod, a thermocouple and a controller, wherein after water is injected into the wax melting tank, a wax mold to be subjected to wax melting is put into the charging basket by manually opening a charging gate; the controller controls the heating mechanism to quickly heat the water; the thermocouple detects the temperature of water in real time; when the temperature reaches a preset temperature, the controller controls the heating mechanism to stop working, the cylinder pushes the charging basket to move downwards into the wax melting tank to perform wax melting, and the molten wax flows out from the wax mold; and compressed air is pumped into the air injection pipe, and the compressed air is blown out via a vent hole to enable the water to produce turbulence, thereby accelerating the outflow of the molten wax. The device is simple in structure, high in automation degree and simple and convenient to operate, effectively improves the production efficiency and eliminates the potential safety hazard caused by manual feeding; and meanwhile, the device realizes quick and uniform heating and is high in efficiency.

Description

technical field [0001] The invention relates to a mechanical device, in particular to an automatic wax-melting device for a soaking-type casting wax pattern. Background technique [0002] Wax mold precision casting, also known as lost wax casting or investment casting, the specific casting method is: first make a model of the casting to be made with wax material, and weld the model to the sprue rod with the same material to make Dip the module (when the casting is large, it can be a single group), dip the refractory paint (a mixture of water glass or silica sol and fine sand) on the surface of the module, and then sprinkle refractory sand, (dip and sand should be repeated several times , so that the sand layer is thick enough), after it is dry and solidified, heat the mold group, release the wax material from the gate, form an empty shell, roast the empty shell to make it a strong mold shell, and pour the metal liquid from the pouring It is poured into the mouth, and after ...

AI Technical Summary

Problems solved by technology

When separating the wax material, the wax material is generally placed in the heating pool for heating, and the wax material will automatically come out after being heated. At present, many manufacturers still use manual feeding to put the wax mold into the heating pool. Due to the high temperature of the heating pool , the operator may be scalded, which poses a certain safety hazard. At the same time, the efficiency of manual operation is low, and since the heating pool is mostly directly heated by a heating tube, the surface area of ​​the heating tube is under the surface area, and the heating is uneven.
