[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 3As shown, the denture plaster model parting machine described in the utility model comprises a flip plate 3, a base 7 and a motor 1 with one end fixed on the top surface of the base 7; a saw disc 2 is fixed on the other end of the motor 1; a rotating rod 302 is arranged at the bottom of the flip plate 3; the rotating rod 302 is rotatably connected to the top surface of the base 7;

[0025] A positioning groove 301 is provided on the surface of the flip plate 3; the positioning groove 301 and the saw disc 2 are arranged on the same vertical plane; the flip plate 3 is connected with a gravity traction module for driving the flip plate 3 to flip upward and reset; a limit block 702 is provided on the base 7; the limit block 702 is arranged on a side of the rotating rod 302 close to the gravity traction module; the limit block 702 is used to limit the flipping angle of the flip plate 3 to prevent the flip plate 3 from being pulled over by the gravity traction module;

[0026] The motor 1 drives the saw disk 2 to rotate, and the gypsum model is held by hand and placed on the surface of the flip plate 3. After the cutting line of the gypsum model is aligned with the positioning groove 301, the hand holding the gypsum model overcomes the resistance of the gravity traction module to flip the flip plate 3, so that the saw disk 2 passes through the positioning groove 301 and cuts the cutting line of the gypsum model. The parting of the gypsum model of this structure only requires one-handed operation, which reduces labor intensity, and uses the positioning groove 301 as a cutting line reference for the gypsum model to improve the cutting position accuracy.

[0027] As a preferred embodiment of the utility model, the gravity traction module includes a steel cable 4 with one end fixed on the flip plate 3 and a counterweight block 6 connected to the other end of the steel cable 4; the gravity of the counterweight block 6 provides pulling force for the flip plate 3, thereby simplifying the structure for resetting the flip plate 3.

[0028] As a preferred embodiment of the utility model, the counterweight block 6 is a hollow box; a water inlet 601 is provided on the top of the hollow box; a drain valve 12 is connected to the bottom of the hollow box; according to the operator's usage habits, water is injected into the hollow box through the water inlet 601 to adjust the total weight of the counterweight block 6, and the feel of the flip plate 3 being pressed can be adjusted. The drain valve 12 is used to discharge the water in the hollow box to adjust the weight of the counterweight block 6.

[0029] As a preferred embodiment of the present invention, an opening groove 701 is provided on the side surface of the base 7; the opening groove 701 extends in the vertical direction; the counterweight block 6 is arranged inside the opening groove 701; a guide wheel 5 is fixed inside the opening groove 701; the steel cable 4 passes around the guide wheel 5;

[0030] The counterweight block 6 is protected by the opening groove 701 to prevent the counterweight block 6 from being shaken by collision. The guide wheel 5 is used to guide and organize the steel cable 4.

[0031] As a preferred embodiment of the utility model, a steel cable sleeve 11 is fixed on the base 7 and is sleeved on the outside of the steel cable 4; a limiting clamp is arranged on the steel cable 4; the limiting clamp is arranged between the steel cable sleeve 11 and the counterweight 6; when the flip plate 3 is compressed, the steel cable 4 is pulled, and when the limiting clamp contacts the steel cable sleeve 11, the flip plate 3 cannot continue to flip, thereby limiting the flip angle of the flip plate 3.

[0032] As a preferred embodiment of the utility model, the limit clamp consists of a sliding sleeve 13 slidably connected to the outside of the steel cable 4 and a locking screw 14 threadedly connected to the sliding sleeve 13; the locking screw 14 is used to lock the sliding sleeve 13 at the upper limit of the steel cable 4. After loosening the locking screw 14, the maximum stroke of the swing angle of the flip plate 3 can be adjusted, which can match plaster molds of different thicknesses.

[0033] As a preferred embodiment of the present invention, a roller 15 is provided on the surface of the counterweight block 6 close to the base 7; the roller 15 is used to form a rolling connection with the side surface of the base 7, thereby reducing the resistance between the counterweight block 6 and the surface of the base 7, so that the sliding of the counterweight block 6 is smoother.

[0034] As a preferred embodiment of the utility model, a dust collecting hood 10 is provided on the top surface of the base 7; the opening of the dust collecting hood 10 is arranged opposite to the flip plate 3; a dust filter 8 is fixed on the base 7; the dust filter 8 is connected to the dust filter 8 through a connecting pipe 9; a filter element and a negative pressure device are provided inside the dust filter 8, which is essentially the same as the prior art, so it is not described in detail. The dust filter 8 is used to generate negative pressure in the dust collecting hood 10 to collect the dust generated by cutting.
