[0003] The production process of investment casting is: waxing, slurrying, wax melting, pouring, etc. Due to the cumbersome production process, most of the existing investment casting equipment is in the assembly line mode, but the disadvantage of the assembly line mode is that every After completing one step, the material needs to be transferred. The transfer process will not only increase the temperature difference of the material but also increase the risk of material damage. Therefore, an investment casting equipment that utilizes the fluidity of wax came into being.

The invention relates to the technical field of precision casting investment casting, and discloses investment casting equipment utilizing wax fluidity. The investment casting equipment comprises a shell, a wax groove is formed in the shell, a rotating shaft is movably connected to the top of the wax groove, a power assisting plate is movably connected to the surface of the rotating shaft, fan blades are movably connected to two sides of the power assisting plate, bevel gears are movably connected to the two ends of the rotating shaft, extrusion plates are movably connected to the surfaces ofthe bevel gears, spring rods are movably connected to the surfaces of the extrusion plates, pressing plates are movably connected to the ends, away from the extrusion plates, of the spring rods, pushrods are movably connected to the surfaces of the spring rods, a feeding box is movably connected to the other ends of the push rods, and a sliding groove is formed in the feeding box. When the connecting part of the spring rod and the push rod is pushed, the wax oil is solidified and formed, and at the moment, the material storage layer is stressed to extrude mud in the material storage layer outand flow to the surface of the wax groove to finish the work of the mud mold, so that the effect of stable-pressure forming can be achieved without transfer.
Description
technical field [0001] The invention relates to the technical field of investment casting of precision castings, in particular to equipment for investment casting using wax fluidity. Background technique [0002] Precision casting refers to the general term for the process of obtaining precise size castings. Compared with the traditional sand casting process, the size of the castings obtained by precision casting is more accurate and the surface finish is better. Precision casting includes: investment casting, ceramic casting, metal casting, etc., among which investment casting has the surface finish of investment casting It is widely used in industry because of its advantages such as relatively high efficiency and substantial saving of metal raw materials. [0003] The production process of investment casting is: waxing, slurrying, wax melting, pouring, etc. Due to the cumbersome production process, most of the existing investment casting equipment is in the assembly line ...
