Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an anti-collision injection mold. Background Technology

[0002] Injection molds are precision tools used for molding plastic products. Molten plastic is injected into a mold cavity under high temperature and pressure, and after cooling, it forms a product with a specific shape. Plastic molds are used in the plastics processing industry in conjunction with plastic molding machines to give plastic products a complete shape and precise dimensions. Due to the wide variety of plastics and processing methods, as well as the varying complexity of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse. Injection molds can be used in fields such as communication equipment, automotive parts, aerospace components, and household goods.

[0003] Based on the search, Chinese patent application number CN201721898643.8 discloses a household appliance opening injection molding die, including an upper mold, a lower mold and a worktable. Four guide pillars are fixedly connected to the four corners of the upper end of the worktable. This utility model has a simple structure and reasonable design, which can effectively improve work efficiency. At the same time, the device has good sealing performance, which improves product quality. In addition, it can also prevent the molten plastic from cooling in the injection port.

[0004] The aforementioned patented device has the following shortcomings when in use: After the workpiece is formed, traditional injection molds lack an auxiliary ejector mechanism, making it inconvenient for operators to remove the formed workpiece from the lower mold, which increases the workload of operators and reduces the efficiency of the device.

[0005] To address the aforementioned issues, a collision-resistant injection mold is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an anti-collision injection mold. By using this device, the problem in the background art is that after the workpiece is formed, the lack of an auxiliary ejection mechanism makes it inconvenient for the operator to remove the formed workpiece from the lower mold, which increases the workload of the operator and reduces the efficiency of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a collision-resistant injection mold, comprising a worktable, an upper mold assembly disposed at the upper end of the worktable, a limiting cavity disposed on the top surface of the worktable, a first motor fixedly connected to the outer side of the worktable, and two sets of anti-collision support plates fixedly connected to the top of the worktable. A moving block is slidably connected to the inner cavity of the limiting cavity, and a lower mold body is fixedly connected to the top of the moving block. The lower mold body is slidably connected between the two sets of anti-collision support plates, and four sets of holes are disposed on the top surface of the lower mold body. A top plate is disposed at the upper end of the worktable, and the upper mold body is disposed at the bottom of the top plate. The upper mold body and the lower mold body are mutually matched. A positioning rod is fixedly connected to the bottom of the top plate, and four sets of positioning rods are disposed, with the four sets of positioning rods respectively matching the four sets of holes.

[0008] Preferably, a through pipe is provided at the top of the top plate, and a forming cavity groove is provided in the middle of the lower mold body, and the through pipe is connected to the forming cavity groove in the lower mold body.

[0009] Using the above-mentioned mechanism, the tube facilitates the operator in introducing injection molding material into the molding cavity.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the top of the workbench, and four sets of hydraulic cylinders are provided. The top plate is fixedly connected to the output ends of the four sets of hydraulic cylinders.

[0011] Using the above mechanism, the upper mold and the lower mold are closed by a hydraulic cylinder.

[0012] Preferably, a spring shock absorber is fixedly connected inside each of the holes, and a rubber round pad is fixedly connected to the top of the spring shock absorber. The rubber round pad is slidably connected inside the hole, and the positioning rod matches the rubber round pad.

[0013] By employing the aforementioned mechanism, the combined action of spring shock absorbers and rubber round pads buffers the impact force during the mold closing process, thereby enhancing the equipment's protective performance.

[0014] Preferably, a first threaded rod is rotatably connected inside the worktable, the first threaded rod is fixedly connected to the output end of the first motor, and the moving block is threadedly connected to the outer periphery of the first threaded rod.

[0015] The above mechanism uses a threaded rod to adjust and move the position of the lower mold, making it easier for the operator to remove the workpiece from the lower mold.

[0016] Preferably, an automatic telescopic rod is fixedly connected to the bottom of the inner cavity of the lower mold body, and four sets of the automatic telescopic rod are provided.

[0017] Using the above mechanism, the workpiece is ejected from the forming cavity by the push of the automatic telescopic rod.

[0018] Preferably, a sealing sliding plate is slidably connected to the inner cavity of the lower mold body, the sealing sliding plate is fixedly connected to the output ends of the four sets of automatic telescopic rods, and a top material plate is fixedly connected to the top of the sealing sliding plate, and the sealing sliding plate moves synchronously with the top material plate.

[0019] The above-mentioned mechanism improves the sealing performance of the forming cavity groove in the lower mold by using a sealing sliding plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model discloses an anti-collision injection mold. When using the device, multiple sets of hydraulic cylinders are simultaneously activated and contracted, causing the top plate to descend until the top plate closes the upper mold body onto the top of the lower mold body. The upper and lower mold bodies complete the mold closing process. At this time, four positioning rods correspond to four sets of cavities, inserting into the cavities and contacting the rubber pads. Simultaneously, the spring damper is compressed. The spring damper uses the commercially available ZTB model spring damping damper mechanism, a mature existing technology. The spring needs to work with damping or a shock absorber to achieve buffering. Its working principle utilizes damping to convert mechanical energy into heat energy. The rubber pad provides a buffering effect, possessing excellent elasticity and buffering performance, absorbing impact and vibration, and reducing noise. The combination of the spring damper and the rubber pad facilitates the mold closing process of the buffer protection device, preventing damage caused by excessive closing force between the upper and lower mold bodies. This design enhances the anti-collision performance of the injection mold and improves the device's protective capabilities.

[0022] 2. After the device completes mold closing, the user introduces injection molding material into the through pipe, filling the molding cavity of the lower mold body with material. After the workpiece in the molding cavity of the lower mold body cools and solidifies, multiple sets of hydraulic cylinders are simultaneously activated. These cylinders extend simultaneously, causing the top plate to rise until the upper mold body is completely away from the lower mold body. To facilitate material removal by the operator, the first motor is activated. The first motor drives the first threaded rod to rotate forward. The first threaded rod drives the moving block to slide horizontally along the limit cavity track. The moving block moves the lower mold body and the workpiece away from the upper mold body. The lower mold body slides between two sets of anti-collision support plates, improving the stability of the lower mold body's movement. When the lower mold body moves to the end of the worktable... Simultaneously, multiple sets of automatic telescopic rods are activated, extending at the same time. These rods push the sealing sliding plate and the top plate upwards until the top plate moves the workpiece from the top surface to the outside of the lower mold body. At this point, the workpiece is ejected, and the operator can remove it from above the top plate. Simultaneously, the multiple sets of automatic telescopic rods retract, causing the top plate to descend back to its original position within the lower mold body. Then, the first motor is activated, driving the first threaded rod to rotate in the opposite direction. The first threaded rod drives the moving block and the lower mold body to move horizontally towards the upper mold body until the lower mold body returns to its position directly below the upper mold body. The first motor is then deactivated. This setup, through an auxiliary mechanism, facilitates material removal from the injection mold by the operator, improving the working efficiency of the device.

A moving block 14 is slidably connected to the inner cavity of the limiting cavity 12, and a lower mold body 15 is fixedly connected to the top of the moving block 14. The lower mold body 15 is slidably connected between the two sets of anti-collision support plates 13. The top surface of the lower mold body 15 has four sets of holes 151. A top plate 21 is provided at the upper end of the worktable 1, and an upper mold body 24 is provided at the bottom of the top plate 21. The upper mold body 24 and the lower mold body 15 are matched with each other. A positioning rod 23 is fixedly connected to the bottom of the top plate 21. Four sets of positioning rods 23 are provided, and the four sets of positioning rods 23 are matched with the four sets of holes 151 respectively.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example 1:

[0034] A through pipe 22 is provided on the top of the top plate 21, and a forming cavity groove is provided in the middle of the lower mold body 15. The through pipe 22 is connected to the forming cavity groove in the lower mold body 15. A hydraulic cylinder 3 is fixedly connected to the top of the worktable 1. There are four sets of hydraulic cylinders 3. The top plate 21 is fixedly connected to the output end of the four sets of hydraulic cylinders 3. A spring shock absorber 232 is fixedly connected inside each set of cavity 151. A rubber round pad 231 is fixedly connected to the top of the spring shock absorber 232. The rubber round pad 231 is slidably connected inside the cavity 151. The positioning rod 23 matches the rubber round pad 231.

[0035] Example 2:

[0036] The workbench 1 is rotatably connected to a first threaded rod 16, which is fixedly connected to the output end of a first motor 11. A moving block 14 is threadedly connected to the outer periphery of the first threaded rod 16. An automatic telescopic rod 154 is fixedly connected to the bottom of the inner cavity of the lower mold body 15, and four sets of automatic telescopic rods 154 are provided. A sealing sliding plate 153 is slidably connected to the inner cavity of the lower mold body 15, and the sealing sliding plate 153 is fixedly connected to the output ends of the four sets of automatic telescopic rods 154. A top plate 152 is fixedly connected to the top of the sealing sliding plate 153, and the sealing sliding plate 153 and the top plate 152 move synchronously.

[0037] In summary, this utility model discloses an anti-collision injection mold. When using the device, multiple sets of hydraulic cylinders 3 are simultaneously activated and retracted, causing the top plate 21 to descend until it causes the upper mold body 24 to close on top of the lower mold body 15. The upper mold body 24 and lower mold body 15 complete the mold closing process. At this time, four positioning rods 23 correspond to four sets of cavities 151, and the positioning rods 23 are inserted into the cavities 151. The positioning rods 23 contact the rubber round pads 231, and simultaneously, the spring shock absorbers 232 are compressed. The spring shock absorbers 232 are commercially available ZTB models. Spring-damped shock absorbers are a mature, existing technology on the market. Springs need to be used in conjunction with dampers or shock absorbers to achieve cushioning. Their working principle utilizes damping to convert mechanical energy into heat energy. Simultaneously, the rubber round pad 231 provides cushioning, exhibiting excellent elasticity and cushioning performance, absorbing impact and vibration, and reducing noise. Furthermore, the combination of the spring shock absorber 232 and the rubber round pad 231 facilitates the mold-closing process of the cushioning protection device, preventing damage to the device caused by excessive closing force between the upper mold body 24 and the lower mold body 15. This design helps prevent collisions in the injection mold and improves the device's protective performance.

[0038] After the device completes mold closing, the user introduces injection molding material into the through pipe 22, filling the molding cavity of the lower mold body 15 with material. After the workpiece in the molding cavity of the lower mold body 15 cools and solidifies, multiple sets of hydraulic cylinders 3 are simultaneously activated. These cylinders extend simultaneously, causing the top plate 21 to rise until the upper mold body 24 is completely away from the lower mold body 15. To facilitate material removal by the operator, the first motor 11 is activated. The first motor 11 drives the first threaded rod 16 to rotate forward. The first threaded rod 16 drives the moving block 14 to slide horizontally along the track of the limiting cavity 12. The moving block 14 moves the lower mold body 15 and the workpiece away from the upper mold body 24. The lower mold body 15 slides between two sets of anti-collision support plates 13, improving the stability of the lower mold body 15 during movement. When the lower mold body 15 moves to the end of the worktable 1, multiple sets of hydraulic cylinders 3 are activated simultaneously. Multiple sets of automatic telescopic rods 154 extend simultaneously, pushing the sealing sliding plate 153 and the top plate 152 upwards until the top plate 152 moves the workpiece on the top surface to the outside of the lower mold body 15. At this point, the workpiece is ejected, and the operator can remove the workpiece from above the top plate 152. Simultaneously, the multiple sets of automatic telescopic rods 154 retract, causing the top plate 152 to descend to its original position inside the lower mold body 15. Then, the first motor 11 is activated, driving the first threaded rod 16 to rotate in the opposite direction. The first threaded rod 16 drives the moving block 14 and the lower mold body 15 to move horizontally towards the upper mold body 24 until the lower mold body 15 returns to the position directly below the upper mold body 24. The first motor 11 is then turned off. This setup, through an auxiliary mechanism, facilitates the operator's removal of material from the injection mold and improves the working efficiency of the device.
