Description

Technical Field

[0001] This application relates to the field of injection mold processing technology, and in particular to a processing technology for injection molds. Background Technology

[0002] The specific principle of injection molding is that the heated and molten plastic raw material is pushed into the mold cavity of the plastic mold by the screw of the injection molding machine under high pressure. After cooling and solidification, a plastic molded product is obtained. The plastic mold is usually composed of two parts: a moving mold and a fixed mold. The moving mold is installed on the moving platen of the injection molding machine, and the fixed mold is installed on the fixed platen of the injection molding machine. During injection molding, the moving mold and the fixed mold close to form the gating system and the cavity. When the mold is opened, the moving mold and the fixed mold separate to remove the plastic product.

[0003] Patent publication number CN116038497A discloses an injection mold processing technology that can improve the efficiency of detecting the levelness of the injection mold's side surface. The process includes the following steps: S1: Installing and clamping the injection mold in the center of the processing device, with the injection side of the mold facing upwards; S2: Detecting the levelness of the injection mold's side surface using the processing device; S3: Precisely identifying the protruding positions on the injection mold's side surface using the processing device; S4: Grinding the protruding positions on the injection mold's side surface.

[0004] The above process involves manually controlling a grinding device to move to the uneven area after inspecting the surface flatness of the injection mold. However, in actual inspection, if the uneven area is small, even if it is detected, the lack of a corresponding marking function may prevent the naked eye from observing the uneven area in time during subsequent manual processing. This directly affects the grinding work and has certain limitations in its use. Summary of the Invention

[0057] The clamping mechanism 4 includes a mounting plate 41, which is fixedly connected to the bottom of the platform plate 1. The platform plate 1 has a processing groove 42 and a cavity 43.

One end of the second bidirectional threaded rod 48 is rotatably connected to the inner side of the mounting plate 41. Two second threaded blocks 49 are provided on the outside of the second bidirectional threaded rod 48. The second threaded blocks 49 are threadedly connected to the second bidirectional threaded rod 48. The bottom of the second threaded blocks 49 is in contact with the inner side of the mounting plate 41. A push plate 491 is fixedly connected to the top of the second threaded blocks 49. The first telescopic rod 44 and the second telescopic rod 45 pass through the two push plates 491 respectively, and the first telescopic rod 44 and the second telescopic rod 45 are rotatably connected to the two push plates 491 respectively. After the push plate 491 moves, it can drive the first telescopic rod 44 and the second telescopic rod 45 to extend and retract.

[0059] A flipping assembly is provided inside the cavity 43. The flipping assembly includes a gear 492, which is fixedly connected to the outside of the second telescopic rod 45. A control plate 493 is slidably connected inside the cavity 43. A rack 494 is fixedly connected to the bottom of the control plate 493.

A rectangular plate 495 is fixedly connected to the top of the control plate 493. A third electric push rod 496 is fixedly connected to one side of the rectangular plate 495. The third electric push rod 496 is fixedly connected inside the cavity 43. When the third electric push rod 496 is working, it can push the rectangular plate 495.

[0060] In actual operation, the device is first connected to the power supply. After the injection mold to be processed is placed between the two clamping plates 46, the second motor 47 works and drives the second bidirectional threaded rod 48 to rotate. The second bidirectional threaded rod 48 drives the two external second threaded blocks 49 to move towards each other. The second threaded blocks 49 drive the push plate 491 to move. Then the two push plates 491 drive the first telescopic rod 44 and the second telescopic rod 45 to extend respectively. At this time, the distance between the two clamping plates 46 is reduced until the two clamping plates 46 tightly clamp the injection mold, thus completing the clamping and positioning of the injection mold.

[0061] After rotating the first bidirectional threaded rod 399 inside the first rectangular frame 34 or the second rectangular frame 35, the first bidirectional threaded rod 399 drives the two first threaded blocks 381 on the outside to move towards each other or away from each other. After the first threaded blocks 381 move, they drive the bottom push-pull rod 385 to flip, causing the push-pull rod 385 at the top of the connecting plate 383 and the auxiliary frame 384 to push and pull the connecting plate 383 and the auxiliary frame 384 up and down respectively, realizing the lifting function. After the above positioning work is completed, first rotate the first bidirectional threaded rod 399 inside the first rectangular frame 34. Then, as can be seen from the above steps, the connecting plate 383 can be lowered. The connecting plate 383 drives the control plate 382 to move. The control plate 382 drives the control rod 389 to move. The control rod 389 drives the mounting frame 36 to move. By adjusting the height of the mounting frame 36, the detection wheel 386 can touch the mold surface. Continue to adjust the height and stop the sliders 387 at both ends of the detection wheel 386 in the middle position of the two adjacent control rods 389.

[0062] After the detection wheel 386 is adjusted, the first electric push rod 33 pushes the movable block 31. The movable block 31 then moves the first rectangular frame 34 and the second rectangular frame 35. Based on the above principle, the detection wheel 386 can then roll on the top surface of the mold. If a depression or protrusion appears during the rolling process, the detection wheel 386 at the top of that depression will fall due to gravity or be lifted by the protrusion. The slider 387 will then touch the corresponding switch. When the switch is touched, the first motor 39, positioned opposite to the direction of travel of the detection wheel 386, operates and drives the connected first threaded adjusting rod 38 to rotate. The first threaded adjusting rod 38 then moves the moving block 391. When the moving block 391 moves to the position of the corresponding detection wheel 386, as the detection wheel 386 continues to travel until the marker pen 393 is just above the uneven position, the electromagnet 395 is de-energized and stops attracting the metal block 394. Then, under the influence of gravity, the marker pen 393 quickly descends to the mold surface and forms a mark after touching it. After the electromagnet 395 is re-energized, it attracts the metal block 394 back to facilitate the next marking work. Strip frames 37 are set on both the front and rear sides of the mounting frame 36. No matter which direction the detection wheel 386 travels, once an uneven problem occurs, the marker pen 393 behind it can effectively mark it after the detection wheel 386 passes this position.

[0063] In order to achieve full coverage inspection of the mold surface, the control rod 389 can be pushed after the second electric push rod 371 is working. The control rod 389 drives the mounting frame 36 to move left and right, so that the inspection wheel 386 can cover the gap between the two inspection wheels 386 during the previous inspection, thereby achieving the purpose of full coverage inspection and improving the inspection quality.

[0064] After one side of the mold is inspected, if other sides need to be inspected, the third electric push rod 496 will push the rectangular plate 495. The rectangular plate 495 will drive the rack 494 to move. After the rack 494 moves, it will drive the gear 492 to rotate. The gear 492 will drive the second telescopic rod 45 to rotate. The second telescopic rod 45 will drive the connected clamping plate 46 to rotate. Through the above connection relationship, it can be seen that the clamped mold can be rotated and changed sides. After the flipping is completed, the above similar steps can be repeated to check and mark the flatness of the new side.

[0065] Once the inspection and marking work is completed, the operation of rotating the first bidirectional threaded rod 399 can be repeated. The inspection wheel 386 is retracted upwards, and the grinding device 374 is lowered to fit against the mold surface. The steps of controlling the movement of the inspection wheel 386 are repeated to enable the grinding device 374 to move and grind the marked area after it is started. Compared with unmarked inspection, this effectively avoids the situation where the unevenness is not obvious enough and cannot be identified by the naked eye in time.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
