Description
Technical Field
[0001] This utility model relates to the field of automotive sealing strip technology, specifically a punching device for automatic waste collection. Background Technology
[0002] Automotive sealing strips are one of the important components of automobiles, widely used in car doors, windows, body, seats, sunroofs, engine compartments, and trunks. They play an important role in waterproofing, sealing, sound insulation, dustproofing, antifreeze, shock absorption, heat preservation, and energy saving.
[0003] During the injection molding process of sealing strips, after molding, the sealing strip will adhere to the inner wall of the mold. During the demolding process, the sealing strip is easily damaged, resulting in a low molding rate of the sealing strip mold and failing to guarantee the manufacturing efficiency of the sealing strip.
[0004] To overcome the above-mentioned defects, existing technology (Chinese patent publication number: CN114789483B, application date: 2022-11-22) discloses an automotive sealing strip punching device, including: a drive unit; a first clamping mechanism; a cutter, the cutter having a stepped hole, the cutter being fixedly mounted on the drive end of the drive unit and sealing the stepped hole, the drive unit driving the cutter to move towards or away from the sealing strip, so that the cutter can move between a cutting position and a retracting position; a ejector rod, one end of the ejector rod having a piston part, the other end being a free end, the piston part being sealed and slidably connected in the stepped hole; a pneumatic connector, the pneumatic connector being fixedly mounted on the drive end of the drive unit or on the cutter, and the pneumatic connector communicating with the stepped hole, for connecting an external air source to drive the ejector rod so that the free end pushes the sealing strip waste at the cutting position. This invention provides an automotive sealing strip punching device, which adds a pneumatically driven ejector rod to the cutter, the ejector rod being used to push the sealing strip waste adhering to the cutter, eliminating the need for manual removal of the waste and improving production efficiency.
[0005] While the aforementioned technologies can solve the problems mentioned above, the equipment docking design is not precise enough when punching automotive sealing strips, resulting in insufficient docking accuracy and making it inconvenient for automotive sealing strip production. At the same time, the complex design also makes maintenance difficult, leading to increased production costs for automotive sealing strips. Furthermore, the waste collection mechanism of the aforementioned technologies is not simple enough, which may cause waste to fall and affect processing, and cannot complete the waste collection work comprehensively and efficiently. Utility Model Content
[0006] The purpose of this utility model is to provide a punching device for automatic waste collection, in order to solve the problems mentioned in the background art, such as the insufficient precision of the equipment docking design when punching automotive sealing strips, resulting in insufficient docking overlap accuracy, which is not convenient for the production of automotive sealing strips. At the same time, the complex design is also inconvenient for maintenance, which increases the production cost of automotive sealing strips. The waste collection mechanism of the above-mentioned technology is not simple enough, which may cause waste to fall and affect processing, and cannot complete the waste collection work in a comprehensive and efficient manner.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a punching device for automatic waste collection, comprising a mounting base, auxiliary fixing support frames mounted on both sides of the mounting base, and an engagement transmission mechanism for lifting and lowering a first docking mold mounted on the upper surface of the auxiliary fixing support frames, the engagement transmission mechanism comprising a drive motor, the drive motor being fixedly mounted on the upper surface of the auxiliary fixing support frames, a gear transmission rod mounted on the outer surface of the output end of the drive motor, a limit sliding frame mounted on the upper surface of the auxiliary fixing support frames, and an engagement transmission rack mounted on the outer surface of the limit sliding frame, the first docking mold being mounted at the end of the engagement transmission rack, and an elastic sliding mechanism for transmitting power to a first rotating block mounted on the outer surface of the first docking mold.
[0008] Furthermore, the elastic sliding mechanism includes an L-shaped abutment rod, which is fixedly installed on the outer surface of the first docking mold. An abutment opening and closing door is installed inside the mounting base, and the movement trajectory of the L-shaped abutment rod abuts the top of the abutment opening and closing door. An upper abutment block is installed on the upper surface of the mounting base, and the lower part of the upper abutment block abuts the upper surface of the two sets of abutment opening and closing doors. A second docking mold is installed on the upper surface of the mounting base, and the installation position of the second docking mold corresponds to the movement trajectory of the first docking mold.
[0009] Furthermore, a fixed sliding frame is installed on the lower surface of the abutting opening and closing door, and a sliding extension rod is installed inside the fixed sliding frame. A compression spring is installed on the outer surface of the sliding extension rod, and a rotating docking hollow rod is installed on the outer surface of the end of the sliding extension rod. A second rotating block is installed on the inner side of the mounting base, and the other end of the rotating docking hollow rod is rotatably installed inside the second rotating block.
[0010] Furthermore, the meshing transmission rack meshes with the gear transmission rod, and a sliding inner groove is provided on the side of the meshing transmission rack. The sliding inner groove slides along the outer surface of the limiting sliding frame, and a fixed extension plate is installed on the back of the first docking mold.
[0011] Furthermore, a corresponding sliding frame is installed on the back of the mounting base, and the fixed extension plate slides up and down along the interior of the corresponding sliding frame. The outer surface of the gear transmission rod contacts the outer surface of the meshing transmission rack to form a meshing structure, and the outer surface of the limiting sliding frame contacts the inner surface of the sliding inner groove to form a sliding structure.
[0012] Furthermore, the left and right sides of the fixed extension plate contact the inner surface of the corresponding sliding frame to form a sliding structure, and the meshing transmission rack and the first docking mold are designed as an integral part, and the drive motor contacts the outer surface of the gear transmission rod with the side of the meshing transmission rack to form a transmission structure.
[0013] Furthermore, the inner surface of the fixed sliding frame contacts the side of the first rotating block to form a sliding structure, and the end of the compression spring contacts the front end of the rotating docking hollow rod to form an elastic structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are: when the waste automatic collection punching equipment needs to perform punching operation, the gear transmission rod is started to rotate directly by the drive motor. The rotation of the gear transmission rod drives the first docking mold through meshing transmission rack. The lifting and lowering movement of the first docking mold is limited by the limiting sliding frame and the corresponding sliding frame. This design reduces the cost of the equipment, facilitates maintenance and operation, and improves the operating accuracy of the equipment.
[0015] Furthermore, when the first docking mold moves downward, the L-shaped abutment rod will abut the abutment opening and closing door. At the same time, the sliding extension rod will be pushed downward. The inward opening of the abutment opening and closing door will fit and dock the sliding extension rod with the interior of the rotating docking hollow rod. This design makes the waste collection work more convenient and will automatically reciprocate as the stamping operation continues, which can better complete the waste collection work.
[0016] Furthermore, the movement trajectory of the first docking mold corresponds to the installation position of the second docking mold, and the movement trajectory of the first docking mold is limited by a fixed extension plate. This design makes the equipment more stable, easier to operate and load / unload, and reduces the cost of use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a punching device for automatic waste collection, comprising a mounting base 1, auxiliary fixing support frames 2 mounted on both sides of the mounting base 1, and an engagement transmission mechanism for lifting and lowering a first docking mold 8 mounted on the upper surface of the auxiliary fixing support frame 2, the engagement transmission mechanism comprising a drive motor 3, the drive motor 3 being fixedly mounted on the upper surface of the auxiliary fixing support frame 2, a gear transmission rod 4 mounted on the outer surface of the output end of the drive motor 3, a limiting sliding frame 6 mounted on the upper surface of the auxiliary fixing support frame 2, an engagement transmission rack 5 mounted on the outer surface of the limiting sliding frame 6, a first docking mold 8 mounted at the end of the engagement transmission rack 5, and an elastic sliding mechanism for transmitting power to a first rotating block 16 mounted on the outer surface of the first docking mold 8.
[0026] like Figure 1 , Figure 2 , Figure 4The technical solution shown here, in order to solve the problems of the existing design being inconvenient for punching operations and difficult to maintain, discloses that: the meshing transmission rack 5 and the gear transmission rod 4 mesh with each other, and the side of the meshing transmission rack 5 is provided with a sliding inner groove 7, which slides along the outer surface of the limiting sliding frame 6. A fixed extension plate 13 is installed on the back of the first docking mold 8, and a corresponding sliding frame 14 is installed on the back of the mounting base 1. The fixed extension plate 13 slides up and down along the interior of the corresponding sliding frame 14. The outer surface of the gear transmission rod 4 contacts the outer surface of the meshing transmission rack 5 to form a meshing structure, and the outer surface of the limiting sliding frame 6 contacts the inner surface of the sliding inner groove 7 to form a sliding structure. The left and right sides of the fixed extension plate 13 contact the inner side of the corresponding sliding frame 14 to form a sliding structure. The meshing transmission rack 5 and the first docking mold 8 are designed as an integral piece, and the drive motor 3 contacts the side of the meshing transmission rack 5 through the outer surface of the gear transmission rod 4 to form a transmission structure.
[0027] When the equipment needs to be started for a cutting operation, the drive motor 3, which is fixedly installed on the auxiliary fixed support frame 2, is started directly. This causes the gear transmission rod 4, which is fixedly installed on the outer surface of the output end of the drive motor 3, to rotate synchronously. Since the inner surface of the auxiliary fixed support frame 2 is also fixedly installed on the side of the mounting base 1, the gear transmission rod 4 rotates continuously in a horizontal circular motion. The rotation of the gear transmission rod 4 will synchronously drive the meshing transmission racks 5, which are in contact with each other on the side, to generate a meshing motion. Driven by the meshing motion, the meshing transmission racks 5 slide up and down inside the auxiliary fixed support frame 2. The sliding inner groove 7 opened on the side of the meshing transmission racks 5... The sliding mechanism will slide along the outer surface of the limiting sliding frame 6 fixedly installed on the upper surface of the auxiliary fixed support frame 2 to ensure higher sliding stability. Since the first docking mold 8 is fixedly installed at the end of the meshing transmission rack 5, the first docking mold 8 will be driven to perform synchronous lifting and lowering movements. The second docking mold 9 is installed on the upper surface of the mounting base 1, and the installation position of the second docking mold 9 corresponds to the moving position of the first docking mold 8. The fixed extension plate 13 fixedly installed on the back of the first docking mold 8 will be driven synchronously, and the moving position of the fixed extension plate 13 will be internally limited and slid along the corresponding sliding frame 14 fixedly installed on the upper surface of the mounting base 1.
[0028] like Figure 3 , Figure 5 , Figure 6The technical solution shown, in order to solve the problem of waste collection leakage affecting normal operation in existing designs, discloses: an elastic sliding mechanism including an L-shaped abutment rod 11, which is fixedly installed on the outer surface of the first docking mold 8; an abutment opening and closing door 10 is installed inside the mounting base 1, and the moving trajectory of the L-shaped abutment rod 11 abuts against the top of the abutment opening and closing door 10; an upper abutment block 12 is installed on the upper surface of the mounting base 1, and the lower part of the upper abutment block 12 abuts against the upper surfaces of the two sets of abutment opening and closing doors 10; a second docking mold 9 is installed on the upper surface of the mounting base 1, and the installation position of the second docking mold 9 is the same as that of the first docking mold 8. The moving trajectories correspond to each other. A fixed sliding frame 15 is installed on the lower surface of the door 10, and a sliding extension rod 17 is installed inside the fixed sliding frame 15. A compression spring 18 is installed on the outer surface of the sliding extension rod 17, and a rotating docking hollow rod 19 is installed on the outer surface of the end of the sliding extension rod 17. A second rotating block 20 is installed on the inner side of the mounting base 1, and the other end of the rotating docking hollow rod 19 is rotatably installed inside the second rotating block 20. The inner surface of the fixed sliding frame 15 contacts the side of the first rotating block 16 to form a sliding structure, and the end of the compression spring 18 contacts the front end of the rotating docking hollow rod 19 to form an elastic structure.
[0029] As the first docking mold 8 descends, the L-shaped abutment rod 11 fixedly mounted on its outer surface is synchronously driven. With the continuous movement of the L-shaped abutment rod 11, it abuts against the upper surface of the abutment opening / closing door 10, which is rotatably mounted inside the mounting base 1. Since the abutment opening / closing door 10 is rotatably mounted inside the mounting base 1, it rotates downwards synchronously with the abutment of the L-shaped abutment rod 11. The inward rotation of the abutment opening / closing door 10 drives the first rotating block 16, which is nested and slidably mounted inside the fixed sliding frame 15 fixedly mounted on the lower surface, to press inwards. The sliding extension rod 17, rotatably mounted inside the first rotating block 16, is also synchronously pressed inwards and moves in position. A rotating docking hollow rod 19 is nested and slides on the outer surface of the end of the sliding extension rod 17. Therefore, in the sliding extension rod... When the upper end of the 17 is engaged in the contact operation, the end of the 17 will be retracted into the interior of the rotating docking hollow rod 19. The compression spring 18, which is nested on the outer surface of the sliding extension rod 17, will also be driven to contact the front end of the rotating docking hollow rod 19 for compression and retraction. Since the other end of the rotating docking hollow rod 19 is rotatably installed inside the second rotating block 20 fixedly installed on the inner surface of the mounting base 1, the rotating docking hollow rod 19 will rotate along the interior of the second rotating block 20 due to the drive of the sliding extension rod 17. After the contact opening and closing door 10 is disengaged from the L-shaped contact rod 11, the compression spring 18 releases its elastic potential energy to push the contact opening and closing door 10 out and reset. The upper ends of the two sets of contact opening and closing doors 10 will contact the upper contact block 12 fixedly installed on the upper surface of the mounting base 1 to complete the limiting operation.
