DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4As shown, the utility model provides a technical solution: a grinding machine for processing molds, comprising a base 1, the top of the base 1 is fixedly connected to a fixed table 2, the top of the base 1 is provided with a plurality of clamping mechanisms for fixing the mold, the top of the fixed table 2 is provided with a transverse groove 203, the interior of the transverse groove 203 is provided with a lifting mechanism, the top of the lifting mechanism is provided with a plurality of grinding wheel mechanisms for grinding the mold, the bottom end of the fixed table 2 is provided with a mounting groove 201, the side end of the fixed table 2 is provided with a plurality of vertical grooves 202, and a plurality of spray mechanisms for cooling the grinding wheel mechanism are provided from the top of the base 1 to the interior of the mounting groove 201. Through the setting of the lifting mechanism, the height of the grinding wheel mechanism can be flexibly adjusted, so that there is no need to increase different types of grinding wheel machine tables 305, and molds of various heights and low types can be adapted for grinding processing, thereby greatly reducing the production cost of the mold.

[0022] Furthermore, the clamping mechanism includes a vertical plate 6, which is fixedly installed on the top of the base 1. The side end of the vertical plate 6 is fixedly connected to the cylinder 601, and the side end of the cylinder 601 is fixedly installed with a clamping device 602. During implementation, after the mold is fixed in the clamping device 602, the mold can be driven to move horizontally by starting the cylinder 601, which is convenient for grinding by the grinding wheel mechanism.

[0023] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the lifting mechanism includes a motor 3, which is fixedly installed on the side end of the fixed platform 2, and a bidirectional threaded rod 301 is installed on the output end of the motor 3, and the side end of the bidirectional threaded rod 301 is rotatably set on the inner side end of the transverse groove 203, and the outer end of the bidirectional threaded rod 301 is threadedly connected with a plurality of threaded sleeves 302, and the left and right side ends of each threaded sleeve 302 are rotatably set with a straight plate 303, and a fixed block 304 is rotatably set between the side ends of two adjacent straight plates 303, and the top of the fixed block 304 is fixedly connected with a grinding wheel machine table 305, and the bottom end of the grinding wheel machine table 305 is fixedly connected with a plurality of plug rods 306, and a plurality of slots 204 are opened on the top of the fixed platform 2, and each plug rod 306 is inserted into each slot 204, which can facilitate the limiting of the grinding wheel machine table 305, so as to facilitate the stable lifting and lowering of the grinding wheel machine table 305, and the bottom end of the grinding wheel machine table 305 is fixedly connected with a plurality of fixed plates 307, and the fixed plates 307 are convenient for installing a spray mechanism.

[0024] During implementation, by starting the motor 3 to drive the bidirectional threaded rod 301 to rotate, each threaded sleeve 302 can be driven to achieve opposite translation or reverse translation at the outer end of the bidirectional threaded rod 301. When the two threaded sleeves 302 achieve opposite translation, they will get closer and closer. At this time, each two sets of straight plates 303 rotate at the side ends of each threaded sleeve 302 respectively, and when the two threaded sleeves 302 get closer and closer, the straight plates 303 will gradually move up against the grinding wheel machine table 305. At this time, Figure 2 , which is the state after the grinding wheel table 305 moves up. At this time, it is convenient to grind the higher molds. By controlling the direction of the two-way threaded rod 301 driven by the motor 3, the height of the grinding wheel table 305 can be flexibly controlled. There is no need to increase the grinding wheel tables 305 of different models. A variety of high and low models of molds can be adapted for grinding, thereby greatly reducing the production cost of the molds.

[0025] Furthermore, the grinding wheel mechanism includes a motor 24, which is fixedly mounted on the side end of the grinding wheel machine table 305. A grinding wheel disc 401 is installed at the output end of the motor 24. During implementation, the grinding wheel disc 401 can be driven to rotate by starting the motor 24, thereby facilitating the grinding process of the mold.

[0026] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the spray mechanism includes a pump 5, which is fixedly installed on the top of the base 1, an input pipe 501 is installed at the input end of the pump 5, and the other end of the input pipe 501 is connected to the water tank, and an output pipe 503 is installed at the output end of the pump 5, and a reel 502 is fixedly connected to the inner bottom end of the installation groove 201, and the output pipe 503 is reeled at the outer end of the reel 502, and the end of the output pipe 503 passes through the vertical groove 202 and is installed at the side end of the fixed plate 307, and the end of the output pipe 503 is installed with a high-pressure nozzle 504. In implementation, when the grinding wheel machine table 305 moves up, the output can be driven due to the setting of the fixed plate 307. The tube 503 moves upward, pulling the output tube 503 at the outer end of the winder 502 to realize unwinding, so as to facilitate the spraying and cooling of the grinding wheel disc 401 at the side end of the grinding wheel machine table 305 after the upward movement. By starting the pump 5, the water in the water tank is pumped into the output tube 503, and sprayed out from the high-pressure nozzle 504 through the output tube 503, so as to facilitate the spraying and cooling of the grinding wheel disc 401. When the grinding wheel machine table 305 moves downward, the winder 502 can automatically rewind the unwound output tube 503, so as to avoid the excessively long output tube 503 hanging on the base 1 due to unwinding after the grinding wheel machine table 305 moves upward.

[0027] It is worth noting that the reel 502 is a claber water pipe automatic reel 502 in the prior art, which can automatically reel the water pipe with a slight pull, thereby preventing the water pipe from twisting.

[0028] Working principle: After fixing the mold in the clamping device 602, the mold can be driven to translate by starting the cylinder 601, so that the grinding wheel 401 can be polished. Then, the bidirectional threaded rod 301 can be driven to rotate by starting the motor 3. At this time, each threaded sleeve 302 can be driven to translate toward or away from the outer end of the bidirectional threaded rod 301. When the two threaded sleeves 302 translate toward each other, they will get closer and closer. At this time, each two groups of straight plates 303 rotate at the side ends of each threaded sleeve 302 respectively, and when the two threaded sleeves 302 get closer and closer, the straight plates 303 will gradually move up against the grinding wheel machine table 305. At this time, Figure 2 , which is the state after the grinding wheel table 305 moves up. At this time, it is convenient to grind the higher molds. By controlling the direction of the two-way threaded rod 301 driven by the motor 3, the height of the grinding wheel table 305 can be flexibly controlled. There is no need to increase the grinding wheel tables 305 of different models. A variety of high and low models of molds can be adapted for grinding, thereby greatly reducing the production cost of the molds.

[0029] Since the winder 502 can realize automatic winding of the output tube 503, when the grinding wheel machine table 305 moves up, the setting of the fixed plate 307 can drive the output tube 503 to move up, and pull the output tube 503 at the outer end of the winder 502 to realize unwinding, so as to facilitate the spray cooling of the grinding wheel disc 401 at the side end of the grinding wheel machine table 305 after moving up. By starting the pump 5, water in the water tank is pumped into the output tube 503, and sprayed out from the high-pressure nozzle 504 through the output tube 503, so as to facilitate the spray cooling of the grinding wheel disc 401. When the grinding wheel machine table 305 moves down, the winder 502 can automatically wind up the unwound output tube 503, so as to avoid the excessively long output tube 503 hanging on the base 1 due to unwinding after the grinding wheel machine table 305 moves up.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
