[0002] In the process of making dentures, wax is needed to make molds. Before making the mold, the wax needs to be melted first. After the wax is melted, the melted wax is poured into the model to form the mold needed for making dentures. A wax melting device is a device for melting wax. When the wax melting device melts the wax, the wax is first put into the receiving tank of the wax melting device. Then, a high temperature is generated in the receiving tank of the wax melting device to melt the wax. After the wax is melted, the operator uses an instrument to scoop the melted wax from the receiving tank and pour it into the model to form the mold needed for making dentures.

[0003] In the prior art, dust and impurities will fall into the wax melting tank of the wax melter after use or when idle, and the wax melting tank of conventional wax melters for denture processing is mostly fixed. Due to the deep tank, cleaning difficulty is increased, the process is slow, and the use effect is poor.

[0004] To this end, we propose a denture wax melting device. Utility Model Content

[0023] Two swing rods 8 are symmetrically arranged on both sides of the friction strip 7. The rotating shaft 9 is fixedly installed with a ratchet 11 located outside the swing rod 8.
