[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the starting motor drives the first bevel gear to rotate, which in turn causes the second bevel gear and the bidirectional threaded rod to rotate. The rotation of the second bevel gear pushes the baffle to move, compressing the module so that it rotates around the rotating shaft and fits tightly. After the plastic material is injected into the module, it is plastically solidified. The motor is rotated in the opposite direction to open the baffle, and the spring column pushes the push plate forward to push out the well-plasticized denture. This achieves clamping and fixing of the module, which facilitates demolding after injection molding and improves injection molding efficiency.
[0030] 2. In this utility model, after disinfection, the fixed handle is operated to drive the rotating column to rotate, which in turn causes the second rotating wheel and the pull rope to rotate. The pull rope pulls the first rotating wheel and the baffle, causing the baffle to rise and thus retrieve the disinfected denture. Afterward, the limiting post is inserted into the limiting hole to fix the first rotating wheel. This achieves the disinfection and retrieval of the denture, reduces the risk of infection, facilitates the use by staff, and improves the practicality of the equipment. Attached Figure Description

The rotating column 205 will then drive the rotating wheel 204 to rotate, and pull the rope 203 into the interior of the rotating wheel 204. The rope 203 will then drive the rotating wheel 201 to rotate and pull the baffle 208, causing the baffle 208 to move upward, so that the disinfected denture can be retrieved. After the antibacterial solution is retrieved, insert the limiting post 207 so that the limiting post 207 enters the limiting hole 202 to fix the rotating wheel 201. This achieves the disinfection and retrieval of the denture, reduces the risk of infection, facilitates the use of the equipment by the staff, and thus improves the practicality of the equipment.
