For example, a Chinese patent discloses a "wax melting device for wax mold casting" with an application number of "CN201920953139.6". This device includes a support plate, on the top of which a box body is fixed. On the top of the box body, a top plate is fixed. In the middle position of the top of the top plate, a vertically arranged motor is installed. The output end of the motor is connected to a rotating shaft extending into the box body. At the bottom end of the rotating shaft, a horizontally arranged U-shaped rod is welded. At both ends of the U-shaped rod, push plates are welded. Below the U-shaped rod, a heating plate fixed between the inner walls of the box body is provided. At the edge of the top of the heating plate, an annular ring is fixed. This device can facilitate the movement of the wax body during wax melting, so as to better melt the wax, and at the same time, it can make the melting effect better without solid residue, meeting the actual requirements. However, during its use, it does not have the function of pre-treating wax blocks. The wax blocks are large in volume and slow to melt during melting, affecting the melting efficiency. Summary of the Utility Model
