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] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a side fastening device for a coated sand casting mold includes a base plate 1, a fixed frame 10 and a pressure plate 12. The top of the base plate 1 is equidistantly fixedly connected with columns 7, the top of the columns 7 is fixedly connected with a top plate 6, the bottom of the top plate 6 is provided with a displacement mechanism, the interior of the top plate 6 is slidably connected with a displacement plate 5, the bottom of the displacement plate 5 is fixedly connected with a fixed plate 4, the pressure plate 12 is slidably connected to the interior of the fixed plate 4, the top of the base plate 1 is fixedly connected with a support plate 3, the fixed frame 10 is fixedly connected to the top of the fixed plate 4, a limiting mechanism is provided inside the fixed frame 10, and a rubber pad 2 is provided on the top of the support plate 3.

[0022] First, by placing the mold on the top of the support plate 3, the stability of the mold on the top of the support plate 3 can be increased by the rubber pad 2, and then the edges of several molds can be fixed as needed, so as to take the corresponding pressing plate 12, and then the pressing plate 12 is fixed to the bottom of the fixed plate 4 by rotating the limiting mechanism. In this way, two or more mold edges can be fixed, thereby increasing the applicability of the device. Then, the displacement mechanism is started to drive the displacement plate 5 to move inside the top plate 6, and then the pressing plate 12 at the bottom of the fixed plate 4 is driven to approach the edge of the mold, so as to tighten the edge of the mold. This avoids the problem of fastening the edge of the mold by mold clamps or screws, which has cumbersome fixing methods and complicated installation or disassembly, thereby increasing the practicality of the device.

[0023] like Figure 1-Figure 4 As shown, the limiting mechanism includes a slide groove 22, which is opened inside the fixed frame 10, and the slide groove 22 is slidably connected inside the slide groove 22. The limiting mechanism also includes a clamping block 20, which is slidably connected inside the fixed frame 10, and one end of the clamping block 20 is fixedly connected to one side of the slide block 21. A protrusion 13 is fixedly connected to the top of the pressure plate 12, and a slot 11 is opened on one side of the protrusion 13. One end of the block 20 extends to the inside of the slot 11. A threaded rod 23 is threadedly connected to the inside of the fixed frame 10, and one end of the threaded rod 23 is rotatably connected to one side of the slide block 21.

[0024] When fixing the pressure plate 12, the protrusion 13 is moved to one side of the fixed frame 10, and then one side of the slot 11 is aligned with one end of the block 20, and then the threaded rod 23 is rotated to drive the slider 21 to move inside the slot 22 and drive the block 20 to enter the slot 11, thereby completing the fixing and limiting of the pressure plate 12. This installation method is more convenient and simple. When disassembling, just repeat the above operations, thereby increasing the practicality of the device.

[0025] like Figure 1-Figure 4 As shown, the displacement mechanism includes two second vertical plates 16, the two second vertical plates 16 are fixedly connected to the bottom of the top plate 6, a reciprocating screw 19 is rotatably connected between the two second vertical plates 16, and the outer side of the reciprocating screw 19 is threadedly connected to a displacement block 18, one side of one of the second vertical plates 16 is fixedly installed with a motor 8, one end of the output shaft of the motor 8 is fixedly connected to one end of the reciprocating screw 19, the displacement mechanism also includes two first vertical plates 15, the two first vertical plates 15 are fixedly connected to the bottom of the top plate 6, a sliding rod 17 is fixedly connected between the two first vertical plates 15, the outer side of the sliding rod 17 is slidably connected to the inside of the displacement block 18, a limiting groove 14 is provided inside the displacement plate 5, the limiting groove 14 is slidably connected to the limiting rod 9 inside, and one end of the limiting rod 9 is fixedly connected to one side of the displacement block 18.

[0026] When tightening, the reciprocating screw 19 is driven to rotate by starting the output shaft of the motor 8, and the displacement block 18 is driven to slide on the outside of the slide rod 17, thereby guiding the movement direction of the displacement block 18, and then the limit rod 9 is driven to slide inside the limit groove 14, thereby driving the displacement plate 5 to move inside the top plate 6 and driving the pressure plate 12 to move down to tighten the edge of the mold. This reduces the traditional cumbersome tightening process, thereby increasing the working efficiency of the device.

[0027] The utility model provides a side fastening device for a coated sand casting mold, and the specific working principle is as follows: first, by placing the mold on the top of the support plate 3, the stability of the mold on the top of the support plate 3 can be increased by the rubber pad 2, and then one side of the slot 11 is aligned with one end of the block 20, and then the slider 21 is driven to move inside the slot 22 by rotating the threaded rod 23, and the block 20 is driven to enter the inside of the slot 11, so as to complete the fixed limit of the pressure plate 12, so that the installation method is more convenient and simple, and when disassembling, the above operation can be repeated, thereby increasing the practicality of the device, and finally, by starting the output shaft of the motor 8 to rotate, the reciprocating screw 19 is driven to rotate and the displacement block 18 is driven to slide on the outside of the slide rod 17, so as to guide the moving direction of the displacement block 18, and then the limiting rod 9 is driven to slide inside the limiting groove 14, so as to drive the displacement plate 5 to move inside the top plate 6 and drive the pressure plate 12 to move down to fasten the side of the mold, so as to reduce the traditional cumbersome fastening process, thereby increasing the working efficiency of the device.
