This patent includes a base mechanism, an adjustment mechanism, and a fixing mechanism. The adjustment mechanism is located at the top of the base mechanism, and the fixing mechanism is located at the top of the base mechanism and outside the adjustment mechanism. The base mechanism includes a base plate, with a first sliding groove at the top of the base plate and mounting grooves around the top of the base plate. Mounting screws are movably installed in the mounting grooves. This utility model allows for the clamping and fixing of materials of different sizes through adjustment of the fixing plate and the adjustment plate, thus expanding its application range.

[0019] The effect achieved by the above components is that when the gripper slides along the connecting rod, the limiting block restricts the sliding direction of the gripper and prevents the gripper from slipping off the connecting rod.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 The present invention provides a quick mold accessory positioning fixture, comprising: a base 1 and a cleaning brush 5, a rectangular frame 2 fixedly connected to the upper surface of the base 1, a clamping device 3 provided on the inner wall of the rectangular frame 2, and a storage device 4 provided on the upper surface of the base 1.

[0031] In the embodiments of this utility model, please refer to Figure 1 and Figure 2The clamping device 3 includes a slide groove 301, which is formed on the inner wall of the rectangular frame 2. A slider 302 is slidably connected to the inner wall of the slide groove 301. A fixing plate 305 is fixedly connected to the inner wall of the slide groove 301. A screw 304 is rotatably connected to one side of the fixing plate 305. The screw 304 is rotatably connected to the rectangular frame 2 and threadedly connected to the slider 302. A first clamping plate 303 is fixedly connected to the upper surface of the slider 302. A slide rail 306 is fixedly connected to the inner wall of the slide groove 301. A second clamping plate 307 is slidably connected to the upper surface of 306. A rack 312 is fixedly connected to one side of both the first clamping plate 303 and the second clamping plate 307. A rotating rod 309 is fixedly connected to the inner wall of the slide groove 301. A rotating shaft 310 is rotatably connected to the arc surface of the rotating rod 309. A gear 311 is fixedly connected to the arc surface of the rotating shaft 310. The gear 311 meshes with the rack 312. A motor 313 is fixedly connected to one side of the rectangular frame 2. The output end of the motor 313 is fixedly connected to the screw 304. This achieves the effect of clamping and fixing rod-like parts of different diameters during the processing and positioning of mold parts, preventing the parts from shifting during processing and resulting in insufficient processing accuracy. A fixing ring 314 is fixedly connected to one side of the rectangular frame 2. A protective cover 315 is slidably connected to the inner wall of the fixing ring 314. This achieves the effect of protecting the motor 313 when the motor 313 drives the screw 304 to rotate using the protective cover 315. The protective cover 315 has several heat dissipation holes 316 on the side away from the rectangular frame 2, and these holes 316 are evenly distributed on one side of the protective cover 315. This achieves the effect of dissipating the heat generated when the motor 313 is working. Several rubber strips 308 are fixedly connected to the sides of the first clamping plate 303 and the second clamping plate 307 that are close to each other, and these rubber strips 308 are evenly distributed on the first clamping plate 303 and the second clamping plate 307. This achieves the effect of increasing the friction between the surfaces of the first clamping plate 303 and the second clamping plate 307 when the accessory is clamped using the first clamping plate 303 and the second clamping plate 307, thus improving the clamping and fixing effect.

[0032] In the embodiments of this utility model, please refer to Figure 1 , Figure 3 and Figure 4The storage device 4 includes a connecting plate 401, which is fixedly connected to the base 1. A support plate 402 is fixedly connected to the upper surface of the connecting plate 401. A round rod 403 is fixedly connected to one side of the support plate 402. Two elliptical rings 404 are slidably connected to the arc surface of the round rod 403. A gripper 405 is fixedly connected to the side of the two elliptical rings 404 that are close to each other. A connecting piece 406 is fixedly connected to the side of the support plate 402 away from the round rod 403. A connecting rod 407 is fixedly connected to one side of the connecting piece 406. The gripper 405 is slidably connected to the connecting rod 407. Springs 409 are sleeved at both ends of the connecting rod 407. The two ends of the springs 409 are fixedly connected to the connecting piece 406 and the gripper 405, respectively. This achieves the effect of quickly storing and fixing the brush 5 when it is not needed. Several anti-slip strips 410 are fixedly connected to the sides of the two grippers 405 that are close to each other. The anti-slip strips 410 are evenly distributed on the surface of the grippers 405. When the brush 5 is held between the two grippers 405, the anti-slip strips 410 increase the friction between the grippers 405 and the brush 5, preventing the brush 5 from slipping off the grippers 405. Limiting blocks 408 are fixedly connected to both ends of the connecting rod 407. The limiting blocks 408 have a circular cross-section. When the grippers 405 slide along the connecting rod 407, the limiting blocks 408 restrict the sliding direction of the grippers 405, preventing the grippers 405 from slipping off the connecting rod 407.

[0033] The working principle of the quick mold component positioning fixture provided by this utility model is as follows: When it is necessary to clamp and position the mold component, the motor 313 fixed on one side of the rectangular frame 2 is started, and the output end of the motor 313 drives the connected screw 304 to rotate. Since the screw 304 passes through the rectangular frame 2 and the fixing plate 305 is fixed in the slide groove 301, the screw 304 can be rotated and supported by the rectangular frame 2 and the fixing plate 305. At this time, the slider 302 will move horizontally back and forth along the inner wall of the slide groove 301 by means of the internal thread. When the slider 302 starts to slide in the slide groove 301, the first clamping plate 303 will move in the same direction as the slider 302. When the first clamping plate 303 moves towards the component, the rack 312 located on its side will also move in the same direction with the first clamping plate 303, and then drive the gear 311 to start rotating. Gear 311 rotates on the arc surface of rotating rod 309 via rotating shaft 310 and is supported by rotating rod 309. As rack 312 moves linearly, it drives gear 311 to rotate around rotating shaft 310. Driven by the rotation of gear 311, rack 312 located on the side of second clamping plate 307 produces linear displacement opposite to the direction of movement of rack 312 of first clamping plate 303. This causes second clamping plate 307 to move along slide rail 306 in the opposite direction to first clamping plate 303. At this time, first clamping plate 303 and second clamping plate 307 move towards each other when motor 313 rotates forward, and separate in opposite directions when motor 313 rotates reverse. When moving towards each other, several rubber strips 308 located on the inner sides of first clamping plate 303 and second clamping plate 307 simultaneously contact the workpiece surface. The friction generated by the rubber strips 308 firmly clamps the workpiece between first clamping plate 303 and second clamping plate 307. Because the rotation angle of the screw 304 can precisely control the displacement of the slider 302, the distance between the first clamping plate 303 and the second clamping plate 307 can be adjusted, allowing the fixture to adapt to rod-like accessories of different diameters. During clamping, the slide groove 301 can constrain the movement trajectory of the slider 302, the slide rail 306 guides the sliding direction of the second clamping plate 307, and the meshing of the rack 312 and the gear 311 ensures the synchronicity and symmetry of the displacement of the first clamping plate 303 and the second clamping plate 307, ultimately effectively suppressing positional deviation during accessory processing. At the same time, the fixing ring 314 on the rectangular frame 2 provides sliding support for the protective cover 315, which covers the main body of the motor 313. The evenly distributed heat dissipation holes 316 on its surface dissipate heat during the operation of the motor 313, preventing the motor 313 from overheating and being damaged.

[0034] When brush 5 needs to be stored after use, the elliptical rings 404 can be manually pulled to both sides. When the two elliptical rings 404 sliding along the arc surface of the round rod 403 are moved away from each other by an external force, the grippers 405 will slide along the axial direction of the connecting rod 407. During the sliding process, the springs 409 sleeved at both ends of the connecting rod 407 are stretched by the grippers 405 and undergo elastic deformation, generating a spring force in the opposite direction to the movement of the grippers 405. When the distance between the two grippers 405 is pulled large enough to allow the brush 5 to be placed smoothly between them, the external force is removed. At this point, the stretched spring 409 releases its elasticity, pushing the grippers 405 in the opposite direction along the connecting rod 407 toward the brush 5. This causes the elliptical ring 404 fixed to the grippers 405 to move synchronously along the round rod 403. Ultimately, the two grippers 405 automatically center and close under the restoring force of the spring 409, fixing the brush 5 between them. At this time, several anti-slip strips 410 fixed to the inner side of the grippers 405 are in close contact with the surface of the brush 5, and the frictional resistance between the anti-slip strips 410 and the brush 5 prevents the brush 5 from falling off. Throughout the clamping process, the circular limiting blocks 408 fixed at both ends of the connecting rod 407 constantly constrain the sliding stroke of the gripper 405: when the gripper 405 slides away from the connecting piece 406 along the connecting rod 407, the limiting blocks 408 prevent the gripper 405 from disengaging from the connecting rod 407. The sliding trajectory of the elliptical ring 404 on the circular rod 403 is linked with the sliding trajectory of the gripper 405 on the connecting rod 407, ensuring that the two grippers 405 always maintain parallel movement. The anti-slip strips 410 are evenly distributed when the grippers 405 are closed, increasing the coefficient of friction of the contact surface and making it difficult for the brush 5 to slip off the grippers 405. This device allows for quick storage and retrieval of the brush 5 simply by pulling the elliptical ring 404.
