Abstract
Description
Technical Field
[0001] The utility model relates to a grinding device, in particular to a grinding device used for mold production. Background Art
[0002] Before use, molds require polishing to remove surface burrs. Before polishing, the mold must be secured to the workbench of a polishing device. Existing polishing devices typically use clamps to hold the mold's two outer walls together before polishing. This clamping method is prone to causing the clamps to slip against the mold's outer walls when working with molds with curved or inclined outer walls. This prevents the clamps from properly securing the mold, thus affecting polishing quality. Utility Model Content
[0003] The main purpose of the utility model is to provide a grinding device for mold production, which solves the technical problem of low grinding efficiency and poor grinding effect caused by mold slippage when the existing grinding device is grinding molds with irregular outer surfaces.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a grinding device for mold production, comprising a workbench, a clamping structure and a grinding structure;
[0005] The workbench is provided with limit slots;
[0006] The clamping structure includes a column, a supporting plate, a slider, a lead screw, a worm gear, a worm and a motor. The two ends of one side of the supporting plate are rotatably connected to the column, the column abuts against the inner wall of the mold, the supporting plate is rotatably connected to the slider, the slider is set in a limit groove, the slider extends to the bottom of the workbench, the slider is threadedly connected to the lead screw, and the two ends of the lead screw are respectively provided with a forward thread and a reverse thread, and sliders are provided at the forward thread and the reverse thread. The lead screw is provided with a worm gear, the worm gear is transmission-connected to the worm, and the worm is connected to the output end of the motor;
[0007] The grinding structure is arranged on the top of the workbench.
[0008] As a preferred solution, the grinding structure includes a support frame, a first electric push rod, a connecting block, a second electric push rod and a grinder. The support frame is fixed on the top of the workbench, the vertical rod of the support frame is fixedly connected to one end of the first electric push rod, and the other end of the first electric push rod is fixedly connected to the connecting block. The cross bar of the support frame is provided with a limiting slide groove, the bottom of the connecting block is fixedly connected to the second electric push rod, the second electric push rod passes through the limiting slide groove and extends to the bottom of the cross bar, and the second electric push rod is fixedly connected to the grinder.
[0009] As a preferred solution, the vertical rod is arranged on one side of the workbench, and the horizontal rod extends toward the middle of the workbench.
[0010] The beneficial effects achieved by the utility model are:
[0011] The utility model uses a method in which the columns abut against the inner wall of the mold, replacing the traditional clamping method of using a splint to squeeze the outer wall of the mold. The columns of the utility model directly contact and squeeze the inner side of the mold. Even if the side wall of the mold is an inclined surface, the mold can be well fixed by the columns. At the same time, the columns are rotatably connected to the support plate, that is, the columns can rotate freely to adapt to the inclination angle of the inner wall of the mold, thereby stably and firmly fixing the inner wall of the mold.

Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0018] like Figure 1 、 Figure 2 As shown, the present invention discloses a grinding device for mold production, comprising a workbench 1, a clamping structure 2 and a grinding structure 3. The workbench 1 is used to install the clamping structure 2 and the grinding structure 3. Figure 1 As shown, the workbench 1 is supported by four supporting legs, and a limiting groove 11 is provided on the workbench 1 .
[0019] The clamping structure 2 is used to fix the mold, and the clamping structure 2 includes a column 21, a support plate 22, a slider 23, a screw 24, a worm gear 25, a worm 26 and a motor 27. The column 21 is rotatably connected to the support plate 22, as shown in FIG. Figure 2 As shown, both ends of one side of the support plate 22 are rotatably connected with columns 21. The two columns 21 are respectively located at the two corners of the support plate 22. The columns 21 are away from the center of the workbench 1. When in use, the columns 21 abut against the inner wall of the mold, and the top of the support plate 22 supports the mold.
[0020] like Figure 1 As shown, a slider 23 is slidably connected to the bottom of the support plate 22. The slider 23 is T-shaped. The bottom of the horizontal plate of the slider 23 abuts against the top of the workbench 1. The vertical plate of the slider 23 is inserted into the limiting groove 11. The vertical plate extends to the bottom of the workbench 1. The portion located at the bottom of the workbench 1 is threadedly connected to the lead screw 24. The two ends of the lead screw 24 are respectively provided with a forward thread 241 and a reverse thread 242. A slider 23 is provided at each of the forward thread 241 and the reverse thread 242. A worm gear 25 is provided in the middle of the lead screw 24. The worm gear 25 rotates synchronously with the lead screw 24. The worm gear 25 is transmission-connected to the worm 26. The worm 26 is connected to the output end of the motor 27, that is, the motor 27 drives the worm 26 to rotate. The motor 27 is fixedly mounted at the bottom of the workbench 1.
[0021] The grinding structure 3 is arranged on the top of the workbench 1. Specifically, the grinding structure 3 includes a support frame 31, a first electric push rod 32, a connecting block 33, a second electric push rod 34 and a grinder 35. The support frame 31 is an inverted "T" structure. Figure 2 For example, the vertical rod 312 of the support frame 31 is fixedly arranged on one side close to the long side of the workbench 1, and the horizontal rod 313 is fixedly connected to the vertical rod 312, and the two are vertically distributed. The horizontal rod 313 extends toward the center of the workbench 1, and the horizontal rod 313 is provided with a limiting slide 311. The first electric push rod 32 is arranged on the top of the horizontal rod 313, one end of the first electric push rod 32 is fixedly connected to the side wall of the vertical rod 312, and the other end of the first electric push rod 32 is fixedly connected to the connecting block 33, the bottom of the connecting block 33 is fixedly connected to the second electric push rod 34, the second electric push rod 34 passes through the limiting slide 311 and extends to the bottom of the horizontal rod 313, and the bottom of the second electric push rod 34 is fixedly connected to the grinder 35.
[0022] When in use, the mold is placed on the support plate 22, the column 21 is inserted into the mold groove of the mold, and then the motor 27 is started, the motor 27 drives the worm 26 to rotate, the worm 26 drives the worm wheel 25 to rotate, and further drives the screw 24 to rotate. Figure 1For example, at this time, the slider 23 on the left slides to the left, and the slider 23 on the right slides to the right, so that the columns 21 on both sides move to the left and right, and the columns 21 gradually squeeze the inner wall of the mold. If the inner side of the mold is an inclined surface or a curved surface, the columns 21 rotate according to the force conditions until the column 21 is stabilized and no longer rotates. At this time, the column 21 is in the best position and fixes the mold on the top of the support plate 22. Then, the position of the grinder 35 is adjusted by the first electric push rod 32 and the second electric push rod 34, and the grinder 35 is started to start grinding.
