Description

Technical Field

[0001] This utility model relates to the field of mold processing and fixing technology, specifically a positioning fixture for processing plastic parts molds. Background Technology

[0002] Plastic molds can be used to manufacture plastic products of various shapes, sizes and structures according to the creativity and needs of product designers. In modern manufacturing, plastic parts are widely used in many fields such as automobiles, electronics, medical, and daily necessities due to their advantages such as light weight, low cost and good moldability. Mold processing is a key link in the production of plastic parts, and its quality and precision directly affect the performance and quality of plastic products.

[0003] Currently, in traditional mold processing, positioning often relies on workers' experience and manual operation. For example, when installing mold parts, workers need to determine the position of the parts by visual observation and using simple tools. This method is easily affected by human factors, resulting in low positioning accuracy. For some high-precision plastic parts molds, such errors are unacceptable. At the same time, some traditional mold structures are simple in design and lack dedicated guiding devices for precise positioning. During the mold opening and closing process, parts are prone to displacement and shaking, thus affecting processing accuracy. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a positioning fixture for processing plastic parts molds, comprising,

[0031] Plastic mold 1;

[0032] The processing table 2 includes a processing table 4 and a load-bearing plate 23 fixedly connected to the inner wall of the processing table 4. The inner wall of the processing table 4 is also fixedly connected to a placement plate 30, and the bottom of the positioning box 5 abuts against the top of the placement plate 30.

[0033] Positioning platform 3 includes two positioning boxes 5 movably connected to the top of processing table 4. Plastic mold 1 is fixedly adsorbed on the top of positioning box 5. Inside positioning box 5, five rotating platforms 8 are slidably connected. The rotating end of rotating platform 8 is fixedly connected to guide ring 9. Negative pressure tube 10 is slidably connected inside guide ring 9. Both ends of negative pressure tube 10 are connected to rubber suction head 11. Rubber suction head 11 is adapted to the bottom of plastic mold 1. Two second springs 18 are movably sleeved on the outside of negative pressure tube 10. One end of the two second springs 18 abuts against the two sides of guide ring 9 respectively. Vacuum machine 12 is fixedly installed on the bottom of inner wall of positioning box 5. Vacuum tube 13 is connected to the output end of vacuum machine 12. Vacuum tube 13 is connected to the five negative pressure tubes 10.

[0034] The positioning platform 3 also includes five hydraulic pipes 6 fixedly connected to the bottom of the inner wall of the positioning box 5. The hydraulic pipes 6 are airtightly slidably connected to hydraulic rods 7. The bottom of the hydraulic rods 7 is fixedly connected to a first spring 17. The bottom of the first spring 17 is fixedly connected to the bottom of the inner wall of the adjacent hydraulic pipe 6. The top of the hydraulic rods 7 is fixedly connected to the bottom of the adjacent rotating platform 8. A hydraulic box 14 is fixedly installed on the bottom of the inner wall of the positioning box 5. The hydraulic box 14 is filled with hydraulic oil. A first hydraulic pump 15 is fixedly installed on the bottom of the inner wall of the positioning box 5. The hydraulic box 14 is connected to the first hydraulic pump 15. The output end of the first hydraulic pump 15 is connected to an oil pipe 16. The oil pipe 16 is connected to the five hydraulic pipes 6. A clearance groove 21 is opened on one side of the guide ring 9. The clearance groove 21 is adapted to the vacuum tube 13. A sliding groove 20 is opened inside the guide ring 9. A sliding strip 19 is fixedly connected to the outside of the negative pressure tube 10. The sliding strip 19 is slidably connected inside the sliding groove 20.

[0035] The above-described structure allows for the adsorption and fixation of the plastic mold 1. Specifically, the plastic mold 1 is placed on top of the positioning platform 3. During this process, the bottom of the plastic mold 1 presses against the rubber suction head 11, causing the two second springs 18 outside the negative pressure tube 10 to extend and retract, allowing the negative pressure tube 10 to slide inside the guide ring 9. This brings the two rubber suction heads 11 at the top of the negative pressure tube 10 into contact with the bottom of the plastic mold 1, making it suitable for bottoms of plastic molds of any shape. All the rubber suction heads 11 at the top of the negative pressure tube 10... After all the rubber suction heads 11 are in contact with the bottom of the plastic mold 1, the plastic mold 1 continues to press down. The hydraulic rod 7 slides inside the hydraulic pipe 6, and the first spring 17 extends and retracts, so that the other rubber suction heads 11 can also be in contact with the bottom of the plastic mold 1, ensuring a good adsorption effect. At this time, the first hydraulic pump 15 is started to pump the hydraulic oil inside the hydraulic box 14 into the five hydraulic pipes 6 to prevent the hydraulic rod 7 from sliding inside the hydraulic pipe 6 and affecting the processing of the plastic mold 1. At this time, the vacuum machine 12 is started, and the plastic mold 1 is adsorbed through the vacuum pipe 13, the negative pressure pipe 10 and the rubber suction heads 11.

[0036] It is worth mentioning that when the bottom of the plastic mold 1 is tilted, the negative pressure tube 10 slides inside the guide ring 9. At the same time, the rotating end of the rotating table 8 drives the guide ring 9 and the negative pressure tube 10 to rotate, ensuring that the two rubber suction heads 11 on the negative pressure tube 10 can contact the bottom of the plastic mold 1.

[0037] The drive mechanism 27 is used to drive the two positioning boxes 5 to move respectively. The drive mechanism 27 includes two second hydraulic pumps 29 fixedly installed on the top of the load-bearing plate 23. A hydraulic cylinder 28 is fixedly installed on the top of the load-bearing plate 23. The hydraulic cylinder 28 is filled with hydraulic oil. The input ends of the two second hydraulic pumps 29 are connected to the hydraulic cylinder 28. Two hydraulic columns 24 are fixedly installed on the top of the load-bearing plate 23. The output ends of the two second hydraulic pumps 29 are connected to the adjacent hydraulic columns 24. A connecting block 25 is fixedly connected to the top of the hydraulic columns 24. Several driving blocks 26 are rotatably connected to the top of the two connecting blocks 25. Several driving blocks 26 are slidably connected inside the guide frame 22. One side of each of the two positioning boxes 5 is fixedly connected to one side of the adjacent driving block 26.

[0038] With the above-mentioned structure, two plastic molds 1 can be driven to move and close respectively, improving processing accuracy. Specifically, when the two plastic molds 1 have different heights, when processing the two plastic molds 1 separately, the tops of the two plastic molds 1 are not on the same plane, making it difficult to compare and prone to errors during processing. At this time, the second hydraulic pump 29 at the bottom with the lower height is started, pumping the hydraulic oil inside the hydraulic cylinder 28 into the hydraulic column 24 connected to it. The extended end of the hydraulic column 24 drives the connecting block 25 to move upward. The upward movement of the connecting block 25 drives the driving block 26 on it to move. The driving block 26 moves according to the trajectory of the guide frame 22 until it is level with the top of the other plastic mold 1, and then the plastic mold 1 can be processed.

[0039] It is worth mentioning that when it is necessary to assemble and observe the two plastic molds 1 during the processing, it is only necessary to start the two second hydraulic pumps 29. The two second hydraulic pumps 29 drive the hydraulic column 24 to extend and drive the drive block 26 to move inside the guide frame 22, thereby driving the two positioning tables 3 to move, so that the two plastic molds 1 can be assembled, which facilitates the processing and observation of the plastic molds 1.

[0040] Working principle: When processing plastic mold 1, two plastic molds 1 are placed on top of adjacent positioning platforms 3. During the process of placing plastic mold 1 on top of positioning platform 3, the bottom of plastic mold 1 presses against the rubber suction head 11. The two second springs 18 outside the negative pressure tube 10 extend and retract respectively, causing the negative pressure tube 10 to slide inside the guide ring 9, so that the two rubber suction heads 11 at the top of the negative pressure tube 10 fit against the bottom of the plastic mold 1. This method can be applied to the bottom of plastic molds 1 of any shape. All the rubber suction heads 11 at the top of the negative pressure tube 10 After all the rubber suction heads 11 are in contact with the bottom of the plastic mold 1, the plastic mold 1 continues to press down. The hydraulic rod 7 slides inside the hydraulic pipe 6, and the first spring 17 extends and retracts, so that the other rubber suction heads 11 can also contact the bottom of the plastic mold 1, ensuring a good adsorption effect. At this time, the first hydraulic pump 15 is started to pump the hydraulic oil inside the hydraulic box 14 into the five hydraulic pipes 6 to prevent the hydraulic rod 7 from sliding inside the hydraulic pipe 6 and affecting the processing of the plastic mold 1. At this time, the vacuum machine 12 is started, and the plastic mold 1 is adsorbed through the vacuum pipe 13, the negative pressure pipe 10, and the rubber suction heads 11.

[0041] When the two plastic molds 1 have different heights, the tops of the two plastic molds 1 are not on the same plane, making it difficult to compare them during processing and prone to errors. At this time, the second hydraulic pump 29 at the bottom of the lower mold is started, pumping the hydraulic oil inside the hydraulic cylinder 28 into the hydraulic column 24 connected to it. The extended end of the hydraulic column 24 drives the connecting block 25 to move upward. The upward movement of the connecting block 25 drives the drive block 26 on it to move. The drive block 26 moves according to the trajectory of the guide frame 22 until it is level with the top of the other plastic mold 1, and then the plastic mold 1 can be processed. During the processing, when it is necessary to observe the two plastic molds 1 together, it is only necessary to start the two second hydraulic pumps 29. The two second hydraulic pumps 29 drive the hydraulic column 24 to extend and drive the drive block 26 to move inside the guide frame 22, thereby driving the two positioning tables 3 to move, so that the two plastic molds 1 can be matched, which facilitates the processing and observation of the plastic molds 1.
