[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-2As shown, a casting mold for denture production includes a base 1, on which a shell 11 is arranged, a fixing piece 17 is arranged on the base 1, and fixing blocks 15 are symmetrically arranged on the base 1. A connecting column 16 is arranged on the fixing block 15, and the connecting column 16 is in an arc shape. A connecting shaft 19 is arranged on the connecting column 16, and a plurality of fan blades 20 arranged in a circular array are arranged on the connecting shaft 19, and the fan blades 20 face the fixing piece 17.

[0021] Specifically, when in use, the denture is fixed on the fixing part 17 on the base 1, and then the connecting shaft 19 on the fixing block 15 is started to drive. The connecting shaft 19 is driven by a motor. When the connecting shaft 19 rotates, it drives the fan blades 20 to rotate, and then the denture is processed. Waste chips will be generated during the processing of the denture, and the waste chips on the denture will affect the processing of the denture. When the denture is being processed, the connecting shaft 19 drives the fan blades 20 to rotate to blow away the waste chips.

[0022] In the above scheme, the denture is protected by the base 1 and the shell 11, the denture is fixed by the fixing part 17 on the base 1, the connecting shaft 19 is fixed by the connecting column 16 on the fixing block 15, and the residue on the denture fixed on the fixing part 17 is blown off by the fan blades 20 on the connecting shaft 19, and the residue is blown to the outside to prevent impurities from affecting the processing of the denture.

[0023] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, the fixing member 17 is provided with a plurality of flow holes 24 arranged in a linear array, the base 1 is provided with a slot 12 , a placement box 13 is slidably disposed in the slot 12 , and the placement box 13 is communicated with the flow holes 24 .

[0024] Specifically, a portion of the waste chips falls into the fixed block 15, and then falls into the circulation hole 24, and then falls into the placement box 13 through the circulation hole 24, and the waste chips are collected.

[0025] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, the fixing member 17 is symmetrically provided with a placement portion 18 , and a plurality of elastic members 22 arranged in a linear array are provided in the placement portion 18 .

[0026] Specifically, when the denture is to be fixed, it is placed on the placement portion 18 and the denture is clamped by a plurality of elastic members 22 arranged in a linear array.

[0027] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, one end of the elastic member 22 is fixedly disposed on the inner wall of the fixing member 17 .

[0028] Furthermore, a resisting member 23 is symmetrically arranged on the fixing member 17 , and the other end of the elastic member 22 is fixedly arranged on the resisting member 23 , and the resisting member 23 is arc-shaped.

[0029] Specifically, the denture is fixed in the resistance member 23, the resistance member 23 is deformed inwards, and then the resistance member 23 pushes the elastic member 22 to bear force, thereby fixing the denture.

[0030] Working principle: When in use, the denture is fixed on the fixing part 17 on the base 1, and fixed in the resistance part 23. The resistance part 23 is deformed inward, and then the resistance part 23 pushes the elastic part 22 to bear force to fix the denture, and then the connecting shaft 19 on the fixed block 15 is started to drive. The connecting shaft 19 is driven by a motor. When the connecting shaft 19 rotates, it drives the fan blades 20 to rotate, and then the denture is processed. The denture will produce waste chips during processing, and the waste chips on the denture will affect the processing of the denture. When the denture is processed, the connecting shaft 19 drives the fan blades 20 to rotate to blow away the waste chips. At the same time, part of the waste chips fall into the fixed block 15, and will fall into the circulation hole 24, and fall into the placement box 13 through the circulation hole 24. The waste chips are collected, and the handle 14 is pulled to drive the placement box 13 to move, and the debris is pulled out.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
