Metal casting device with grinding tool sealing function

Abstract

The invention relates to a metal casting device with a grinding tool sealing function. The metal casting device comprises a base, a supporting rod, a cross rod, a forming mechanism and a sealing mechanism, wherein the sealing mechanism comprises a limiting assembly, a driving assembly, a speed reducing assembly, a driven assembly and a sealing assembly. According to the metal casting device with the grinding tool sealing function, forming is achieved through the forming mechanism, sealing of the connecting position of an upper die and a lower die is achieved through the sealing mechanism, anda better forming effect is achieved. Compared with an existing metal casting device, the upper die and the lower die are clamped through the limiting assembly, a better closing effect is achieved, anda better sealing effect is achieved by spraying slurry. Compared with an existing sealing mechanism, online spraying is achieved through linkage of the driving assembly and the sealing assembly, meanwhile, circulating operation of material spraying and material supplementing is achieved through cooperation of two sleeves, the connecting position can be rapidly and repeatedly sprayed through the device, and efficiency is improved.

Description

technical field [0001] The invention relates to a metal casting device with a grinding tool sealing function. Background technique [0002] Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The material to be cast is mostly solid but heated to liquid metal, and the material of the casting mold can be sand, metal or even ceramics. According to different requirements, the method used will be different. The casting molds of special casting include: investment casting , Lost foam casting, metal casting, ceramic casting, etc. [0003] For metal mold casting, the molten metal is generally filled into the closed upper mold and the lower mold, and the molding is completed after it is cooled. During this process, the sealing of the upper mold and the lower mold is particularly important. The sealing ring is sealed, and the sealing ring will wear and other ...

[0003] For metal mold casting, the molten metal is generally filled into the closed upper mold and the lower mold, and the molding is completed after it is cooled. During this process, the sealing of the upper mold and the lower mold is particularly important. The sealing ring is sealed, and the sealing ring will wear and other problems after long-term use, resulting in poor sealing performance, so it needs to be checked and replaced regularly, and the cost is high
