Description

Technical Field

[0001] The utility model relates to the technical field of investment casting, in particular to a convenient multifunctional operating table for mold making. Background Art

[0002] Investment casting is a key technique in industrial casting, playing a significant role in the production of high-precision parts. Wax pattern making, the first of many steps in the investment casting process, ensures high surface quality and tight geometric tolerances for parts, reducing the workload of subsequent finishing and alignment, playing a crucial role in the overall part production process.

[0003] At present, when making wax molds, molten wax is usually injected into a metal mold through a wax injection machine. After the wax mold is solidified, the metal mold is manually pulled out from the wax injection machine platform to the operating table. The metal mold is disassembled and the wax mold is taken out. For some large metal molds, they are bulky and overweight. When manually pulling them out, the friction on the surface of the conventional platform is large, and pulling the metal mold is time-consuming and laborious. At the same time, the wax material is highly sensitive to temperature and has poor fluidity and brittleness at low temperatures. In cold seasons, special heating equipment is required to preheat the mold. Therefore, the disassembled mold needs to be disassembled and transported for heating many times, resulting in low production efficiency. For this reason, we propose a convenient multi-functional operating table for mold making. Utility Model Content
