Wax pressing and wax injecting equipment for precision casting

Abstract

The invention discloses wax pressing and wax injecting equipment for precision casting. The wax pressing and wax injecting equipment for precision casting comprises a base table, lower modules, uppermodules, and wax injecting devices; each lower module comprises a plurality of groups of lower mold bodies; a wax injecting opening is formed in each lower mold; each wax injecting device comprises awax injecting spraying nozzle; each wax injecting spraying nozzle comprises a spraying nozzle head; each spraying nozzle head is connected with a wax injecting body; the outer circumference of each wax injecting body is connected with a feeding device; each feeding device comprises a feeding piece which is arranged outside the corresponding wax injecting body; a feeding pushing device is arrangedat one end of each feeding piece; and a blocking device is arranged at the other end of each feeding piece. According to the wax pressing and wax injecting equipment for precision casting, the upper molds and the lower molds are mutually aligned correspondingly, and the wax injecting devices are telescopically controlled to align the wax injecting openings for injecting wax through fixed telescopic pieces, so that the poured wax slurry enters the lower molds, and servo motors rotate to drive cutting tools to cut the wax in the wax injecting devices; wax injecting pipelines in material stackingframes can be pushed into hollow cylinders of the wax injecting bodies through the feeding pushing devices, so that the replacement of the wax injecting pipelines are realized; and the problem that the wax injecting nozzles are blocked by injected wax is effectively solved.

Description

technical field [0001] The invention relates to the technical field of precision casting equipment, in particular to a precision casting wax injection equipment. Background technique [0002] Investment casting and lost wax casting include pressing wax, repairing wax, forming trees, dipping slurry, melting wax, pouring molten metal and related subsequent treatment processes. The surface is covered with refractory material to make a shell, and then the pattern is melted and discharged from the shell to obtain the corresponding mold. After high-temperature roasting, it can be filled with sand and poured. The investment casting process is complicated and not easy to control, and the existing wax The material has strict standards in the filling process. When the wax slurry is injected into the mold from the sprue, because the sprue is generally on the top or side of the mold, this will cause the injected wax slurry to splash, making the surface quality of the wax mold poor, and ...

AI Technical Summary

Problems solved by technology

[0002] Investment casting and lost wax casting, including wax pressing, wax repairing, tree formation, dipping, melting wax, pouring molten metal and related follow-up processing processes, usually refers to preparing related device shapes from fusible materials, and then remodeling The surface is covered with refractory materials to make a shell, and then the pattern is melted and discharged from the shell to obtain the corresponding mold. After high-temperature roasting, it can be filled with sand and poured. The investment casting process is complicated and not easy to control, and the existing wax The material has strict standards in the filling process. When the wax slurry is injected into the mold from the sprue, because the sprue is usually on the top or side of the mold, this will cause the injected wax slurry to splash and make the surface quality of the wax mold poor. The wax machine assembly line injects wax into the mold. In this way, the wax in the wax injection nozzle will solidify quickly at a certain interval, and the wax injection nozzle is prone to be blocked by wax, resulting in insufficient wax injection process and reduced wax injection efficiency.
