Device and method for rapidly heating and melting female die of complex cavity shell layer

Abstract

The invention relates to a device and method for rapidly heating and melting a female die of a complex cavity shell layer. The device comprises a rack of a frame-shaped structure, the rack is coveredwith a shell, an upper fixing plate and a lower fixing plate which are parallel are installed in the rack at an interval, and a lifting type shielding cover and a lifting mechanism are installed between the upper fixing plate and the lower fixing plate; a heat preservation conveying pump is fixed to the bottom of the rack, one end of the heat preservation conveying pump is connected with a first heat preservation conveying pipeline, the other end of the heat preservation conveying pump is connected with a second heat preservation conveying pipeline, and the second heat preservation conveying pipeline communicates with a discharging port of a hot melt collecting box; and a metal ball vertical lifting mechanism and a metal ball filling and recycling system are installed in the rack, the output end of the metal ball vertical lifting mechanism corresponds to the metal ball filling and recycling system, and a cooling system communicated with the interior of the rack is further installed onthe outer side of the rack. The operation is reliable.

Description

technical field [0001] The invention relates to the technical field of investment casting, in particular to a device and method for rapidly heating and melting a mother mold of a complicated cavity shell. Background technique [0002] In the investment casting process, after the multi-layer refractory coating is made on the surface of the wax pattern and semi-dried, the mold must be heated to melt the wax material of the master pattern and separate from the refractory shell to form a cavity mold shell (term dewaxing). [0003] At present, there are five heating methods in the dewaxing method in the industry: water bath, water vapor, electric radiation, gas flashing, and microwave. [0004] There are two commonly used methods: [0005] One is soaking in a hot water bath (above 90°C), directly immersing the shell mold in hot water, using the hot water to directly heat the shell mold and wax material, so that the wax material melts and floats to the water surface, and the inne...
