By providing the protective device 3, the effect of protecting the grinding and milling device body 1 during the process of grinding the mold is achieved. Since the grinding and milling device body 1 will continuously generate debris and splash to the outside during the process of grinding the mold, it is easy for workers to be injured when observing the process of grinding the mold, which improves the safety of the device. A clamping device 4 is provided on the surface of the placing table 2. By providing the clamping device 4, the effect of clamping the mold to be milled is achieved, and the situation that the grinding and milling device body 1 shakes and affects the grinding standard during the process of grinding the mold is avoided, thereby improving the stability of the device.

[0029] The specific arrangement and function of the protection device 3 and the clamping device 4 will be described in detail below.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the protective device 3 includes a U-shaped frame 301, the U-shaped frame 301 is fixedly connected to the surface of the grinding and milling device body 1, the inner surface of the U-shaped frame 301 is fixedly connected to a fixing rod 302, the arc surface of the fixing rod 302 is rotatably connected to a baffle 303, a fixing plate 304 is fixedly connected to the side of the grinding and milling device body 1 close to the U-shaped frame 301, a plug plate 305 is slidably inserted in the fixing plate 304, one side of the plug plate 305 is fixedly connected to a mounting plate 306, a mounting groove is provided on the side wall of the baffle 303, and the arc surface of the fixing rod 302 is sleeved with two torsion springs 307, and the two ends of the torsion spring 307 are respectively fixedly connected to the baffle 303 and the inner surface of the U-shaped frame 301. Pulling the mounting plate 306 drives the plug plate 305 to slide in the fixed plate 304 until the plug plate 305 is separated from the inner surface of the mounting groove of the baffle 303. The torsion force of the torsion spring 307 drives the baffle 303 to rotate on the arc surface of the fixed rod 302 and automatically fits the surface of the milling device body 1, thereby improving the speed of the device. A spring 308 is fixedly connected to one side of the mounting plate 306 close to the fixed plate 304, and one end of the spring 308 is fixedly connected to one side of the fixed plate 304 close to the mounting plate 306. Pull the baffle plate 303 to rotate on the arc surface of the fixed rod 302, loosen the mounting plate 306, and the elastic force of the spring 308 drives the plug plate 305 to slide in the fixed plate 304 and automatically insert into the mounting groove of the baffle plate 303, thereby improving the convenience of the device. An elliptical plate 309 is fixedly connected to one side of the fixed plate 304, and a blocking rod 310 is slidably inserted in the elliptical plate 309. A round block 311 is fixedly connected to one end of the blocking rod 310, and a moving groove is provided on the surface of the plug plate 305. Pull the mounting plate 306 to drive the plug plate 305 to slide in the fixed plate 304 until the position of the moving groove of the plug plate 305 is aligned with the position of the blocking rod 310 for automatic insertion, so that the staff can limit the position of the plug plate 305, and there is no need to keep pulling the mounting plate 306 during the next opening of the baffle 303.

[0031] Reference Figure 4 As shown, specifically, the clamping device 4 includes a special-shaped block 41, which is fixedly connected to the surface of the placement table 2, a screw 42 is inserted into the inner thread of the special-shaped block 41, one end of the screw 42 is rotatably connected to a clamping plate 43, and a protective pad 46 is fixedly connected to the side of the clamping plate 43 away from the screw 42, and a placement block 44 is fixedly connected to the surface of the special-shaped block 41, and a limit rod 45 is slidably inserted into the placement block 44, and one end of the limit rod 45 is fixedly connected to the clamping plate 43.

The handle 47 is rotated to drive the screw 42 to rotate in the special-shaped block 41, so that the staff can stably rotate the screw 42 and accurately control the tightness of the clamping plate 43.

[0032] Working principle: when the staff needs to open the baffle 303, the baffle 303 is pulled to rotate on the arc surface of the fixing rod 302 to loosen the mounting plate 306, and the elastic force of the spring 308 drives the plug plate 305 to slide in the fixing plate 304 and automatically insert into the baffle plate 303 mounting groove. When the baffle 303 needs to be closed, the mounting plate 306 is pulled to drive the plug plate 305 to slide in the fixing plate 304 until the plug plate 305 is separated from the inner surface of the baffle plate 303 mounting groove. The torsion force of the torsion spring 307 drives the baffle 303 to rotate on the arc surface of the fixing rod 302 and automatically fits the surface of the milling device body 1. By setting the protective device 3, the effect of protecting the milling device body 1 during the milling process of the mold is achieved. Because the milling device body 1 will continuously generate debris to splash to the outside during the milling process of the mold, it is easy for the staff to be injured when observing the mold grinding process, thereby improving the safety of the device.

[0033] When the staff needs to clamp the mold to be milled, the mold to be milled is placed on the surface of the placement table 2, and the handle 47 is turned to drive the screw 42 to rotate in the special-shaped block 41, the screw 42 drives the clamping plate 43 to move, and the clamping plate 43 drives the limiting rod 45 to slide in the placement block 44, thereby avoiding the clamping plate 43 from rotating with the rotation of the screw 42, and the clamping plate 43 drives the protective pad 46 to move. By setting the clamping device 4, the effect of clamping the mold to be milled is achieved, and the situation in which the milling device body 1 shakes and affects the milling standard during the milling process of the mold is avoided, thereby improving the stability of the device.
