Wax injection nozzles for precision casting wax pressing and injection equipment

Abstract

The invention discloses wax injection nozzles for precision casting wax pressing and injecting equipment. The wax injection nozzle comprises fixed telescopic parts, wherein the fixed telescopic partsare arranged on a rotating table on the outer circumference of the bottom of a stand column, and the telescopic ends of the fixed telescopic parts are movably connected with wax injection nozzle bodies; wax injection nozzle bodies comprise nozzle heads, and the nozzle heads are connected with wax injection bodies; and the outer circumferences of the wax injection bodies are connected with feedingdevices, the feeding devices comprise feeding pieces arranged outside the wax injection bodies, feeding pushing devices are arranged at one ends of the feeding pieces, and blocking devices are arranged at the other ends of the feeding pieces. The wax injection nozzles for the precision casting wax pressing and injecting equipment is novel in shape, wax injection pipelines arranged in stacking frames can be pushed into hollow cylinders of the wax injection bodies through the feeding pushing devices, and replacement of the wax injection pipelines is achieved so that the problem that the wax injection nozzle bodies are blocked by wax can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of precision casting equipment, in particular to a wax injection nozzle of 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...

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.
