Description

Technical Field

[0001] The utility model relates to the technical field of mold polishing and shaping fixture structures, in particular to a mold polishing and shaping fixture structure for high-gloss plastic products. Background Art

[0002] During the processing of high-gloss plastic products, an injection molding machine is required to cooperate with a mold for molding. In order to avoid convex spots on the surface of the molded high-gloss plastic products, the mold needs to be polished and shaped regularly. Existing mold polishing is mostly done by holding the mold manually. Even if there is a clamp, the clamp can only clamp the edge of the mold. When adjusting the inclination angle of the mold, due to the large weight of the mold, it is easy to loosen from the clamp under the action of its own gravity. In more serious cases, it will detach from the clamp, which will lead to a poor polishing effect. Utility Model Content

[0023] The preferred embodiment of the mold polishing and shaping fixture structure of a high-gloss plastic product provided by the utility model is as follows Figures 1 to 4 As shown: a mold polishing and shaping fixture structure for a high-gloss plastic product, comprising a base plate 1;

[0024] A mounting plate 2 fixedly mounted on the top of the base plate 1;

[0025] An adjustment clamping assembly 3 disposed on the mounting plate 2;

[0026] and a mold 4 disposed in the adjusting clamping assembly 3, wherein the adjusting clamping assembly 3 comprises an adjusting portion 31, the adjusting portion 31 is located at the top of the mounting plate 2, a rotating portion 32 is disposed at the top of the adjusting portion 31, and a clamping portion 33 is disposed inside the rotating portion 32;

[0027] The adjusting portion 31 includes a guide groove 311 and a latch 318. The guide groove 311 is located at the top of the mounting plate 2. A fixed plate 313 is fixedly installed on the inner wall of the guide groove 311. A double-axis telescopic rod 312 is fixedly installed on the outer wall of the fixed plate 313. A movable plate 314 is slidably provided on the inner wall of the guide groove 311. The extended end of the double-axis telescopic rod 312 is fixedly connected to the outer wall of the movable plate 314. A movable sleeve 1 315 is fixedly installed on the top of the movable plate 314. A movable sleeve 2 316 is slidably provided on the inner side of the movable sleeve 1 315. A movable sleeve 3 317 is slidably provided on the inner side of the movable sleeve 2 316. The latch 318 is connected to the movable sleeve 1 315, the movable sleeve 2 316 and the movable sleeve 3 317 by passing through the through grooves on the movable sleeve 1 315, the movable sleeve 2 316 and the movable sleeve 3 317. 6. The movable sleeve 317 is fixed, and the rotating part 32 includes a mounting frame 321. The mounting frame 321 is fixedly installed on the top of the movable sleeve 317. The inner and outer walls of the movable sleeve 317 are fixedly installed with a motor 322. A rotating shaft 323 is fixedly installed on the output end of the motor 322. A clamp 324 is fixedly installed on the end of the rotating shaft 323 away from the motor 322. The height of the clamp 324 and the distance between the left and right clamps 324 are adjusted by the adjusting part 31 to clamp the mold 4. The rotating shaft 323 is driven to rotate by the motor 322, and then the clamp 324 is driven to rotate, so that the mold 4 rotates a certain angle, so that the polishing equipment can better extend the polishing component into the mold 4 to polish the mold 4, avoiding the problem of polishing dead angles.

[0028] Furthermore, the lengths of the movable sleeve 1 315, the movable sleeve 2 316, and the movable sleeve 317 are the same, and the positions of the through grooves on the movable sleeve 1 315, the movable sleeve 2 316, and the movable sleeve 317 are the same, so that when the pin 318 is inserted into the corresponding through groove to fix the movable sleeve 1 315, the movable sleeve 2 316, and the movable sleeve 317, it only needs to be inserted horizontally without tilting the pin 318.

[0029] Furthermore, the upper half of the clamp 324 is U-shaped, and the lower half is rectangular, and the clamp 324 is clamped at the protrusion on the edge of the mold 4. The upper half of the clamp 324 is used to limit the protrusion on the edge of the mold 4 in the side direction, and the lower half of the clamp 324 is used to support the protrusion on the edge of the mold 4 to prevent the mold 4 from detaching from the clamp 324 under the action of its own gravity when the clamp 324 drives the mold 4 to rotate.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of a mold polishing and shaping fixture structure for a high-gloss plastic product provided by the utility model is as follows: Figures 1 to 4As shown: the clamping portion 33 includes a threaded hole 331 and an adjusting plate 332. The adjusting plate 332 is slidably arranged in the clamp 324. The threaded hole 331 is located on the inner wall of the bottom of the clamp 324. The adjusting plate 332 is fixedly connected to the threaded hole 331 by bolts. A sliding rod 334 is fixedly installed on the outer wall of the adjusting plate 332. A sliding plate 333 is slidably arranged on the outer wall of the sliding rod 334. A threaded rod 335 is fixedly installed on the outer wall of the sliding plate 333 away from the clamp 324. An inner threaded tube 337 is threadedly sleeved on the outer wall of the threaded rod 335. An extension plate 336 is rotatably sleeved on the outer wall of the inner threaded tube 337. An adjustment plate 332 is provided to adjust the space inside the clamp 324 to prevent the protrusion at the edge of the mold 4 from being too small, which would cause the clamp 324 to be unable to clamp the mold 4 well. An extension plate 336 is provided to push the mold 4, that is, the left and right groups of extension plates 336 are used to clamp the mold 4, thereby increasing the contact area of ​​the clamp 324 on the mold 4 and improving the clamping effect on the mold 4. An internal threaded tube 337 is provided so that the internal threaded tube 337 can drive the extension plate 336 to move relative to the threaded rod 335, thereby preventing the protrusion at the edge of the mold 4 from being too long, causing the extension plate 336 to be unable to contact the outer wall of the mold 4.

[0032] Furthermore, limiting rings are fixedly provided at both ends of the internal threaded tube 337 to prevent the extension plate 336 from detaching from the internal threaded tube 337. The extension plate 336 is stuck in the depression at the edge of the mold 4. Compared with the extension plate 336 pressing on the outer wall of the mold 4, the contact area between the extension plate 336 and the mold 4 is larger when the extension plate 336 is stuck in the depression, and the clamping effect is better.

[0033] When the utility model is in use, the double-axis telescopic rod 312 is opened to drive the moving plate 314 to move, thereby making the moving sleeve 1 315, the moving sleeve 2 316, and the moving sleeve 317 move, and the moving sleeve 317 moves to drive the rotating part 32 to move, so that the distance between the clamps 324 in the left and right rotating parts 32 matches the outer diameter of the mold 4, and then the corresponding threaded hole 331 is selected to install the adjustment plate 332 in the clamp 324, and the mold 4 is moved from top to bottom so that the edge protrusion of the mold 4 falls into the clamp 324, and the sliding plate 333 is pulled to move along the sliding rod 334 so that the extension plate 336 is aligned with the concave part of the edge of the mold 4, and the internal threaded tube 337 is rotated so that the internal threaded tube 337 moves along the threaded rod 335, thereby driving the extension plate 336 to move, so that the extension plate 336 extends into the mold 4, and the mold 4 is clamped. When polishing, the motor 322 is turned on to drive the rotating shaft 323 to rotate, and then the clamp 324 rotates to drive the mold 4 to rotate, so that the mold 4 is tilted at a certain angle relative to the polishing equipment, which is convenient for the polishing equipment to extend the polishing part into the mold 4, avoiding the problem of polishing dead angle.
