Description

Technical Field

[0001] The invention relates to the technical field of vacuum slurry dipping machines, in particular to a vacuum slurry dipping machine for hardware products. Background Art

[0002] Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax trimming, tree assembly, slurry dipping, sand pouring, wax melting, molten metal pouring, and post-processing. Lost wax casting uses wax to create a wax mold of the part to be cast. The wax mold is then coated with slurry and sand, and then melted to form a model. High-temperature molten metal is poured into the model. After the metal cools and takes shape, the model is destroyed to obtain the finished product. In existing investment casting, hardware accessories need to be automatically dipped in slurry using a vacuum dipping machine.

[0003] In the prior art, there is a fully automatic vacuum precision casting slurry dipping machine with the announcement number CN115121770A, which includes a first vacuum slurry dipping tank, a vacuum generating device, a sand pouring machine, a multi-axis manipulator and a clamp. The multi-axis manipulator is used to drive the clamp to clamp the workpiece and transfer the workpiece to the first vacuum slurry dipping tank and the sand pouring machine or to take the workpiece out of the first vacuum slurry dipping tank. The purpose of this invention is to provide a fully automatic vacuum precision casting slurry dipping machine, which can automatically transfer the wax mold between the slurry dipping and sand pouring stations, and at the same time can rotate the angle of the wax mold during slurry dipping under a vacuum environment to coat the wax mold all over without dead angles, thereby reducing the problem of low finished product rate due to uneven coating and bubbles in the prior art.

[0004] However, although the existing vacuum dipping machine can perform automated dipping operations on hardware accessories well when in use, the spacing of the hardware accessories placed in the dipping machine is relatively fixed, and the automatic adjustment effect of the spacing of the hardware accessories on the rotating rod is not high, which reduces the effect of adjusting the hanging dipping of different sizes in the dipping machine. At the same time, when the hardware accessories are automatically taken by the robotic arm, the shape of the clamping head is relatively fixed, and the conversion effect of the clamping heads of different shapes is not high. When it is necessary to clamp and load hardware accessories of different sizes, the adaptability and stability of the robotic arm to clamping hardware accessories of different sizes are reduced, which does not meet people's usage needs. For this reason, we propose a vacuum dipping machine for hardware products. Summary of the Invention
