Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to an injection mold for an engineering plastic pad block. Background Technology

[0002] Engineering plastic gaskets are non-metallic gaskets or supports with specific functions, manufactured using engineering plastics through processes such as injection molding. They are widely used in industries such as industry, electronics, automotive, and construction, serving as lightweight, corrosion-resistant, insulating, or shock-absorbing alternatives to traditional metal gaskets.

[0003] After the injection molding of engineering plastic pad blocks is completed, a stripping mechanism is needed to strip the material. However, the existing material falls directly after being stripped and collected. This may cause damage to the material because the distance between the material and the collection trolley is too high. In addition, the existing material feeding position is relatively fixed, which may lead to the material being too concentrated and stacked, thus affecting the material collection effect. To address this, we propose an injection mold for engineering plastic pad blocks. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for engineering plastic pads to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for an engineering plastic pad block, comprising a mounting frame, two sets of mounting plates fixedly mounted on the top of the mounting frame, a fixed mold fixedly mounted on one set of mounting plates, multiple sets of sliding rods fixedly connected between the two sets of mounting plates, a movable mold slidably connected to the outside of the sliding rods, two sets of driving cylinders fixedly mounted on the other set of mounting plates, the output end of the driving cylinders fixedly connected to the movable mold, a material ejection mechanism for material ejection provided on the movable mold, a buffer mechanism for material buffering provided on the mounting frame and corresponding to the movable mold and the fixed mold, and a material receiving mechanism for preventing material accumulation provided on the mounting frame.

[0006] Furthermore, the stripping mechanism includes stripping rods, connecting plates, first springs, connecting seats, and top seats. Multiple sets of stripping rods are arranged through the moving mold. A connecting plate is fixedly connected to one side of the stripping rod, and a connecting seat is fixedly connected to one side of the connecting plate. A top seat is fixedly connected to the mounting plate at a position corresponding to the connecting seat. Multiple sets of first springs are arranged between the moving mold and the connecting plate.

[0007] Furthermore, the buffer mechanism includes a limiting tube, a telescopic rod, a feeding frame, and a second spring. Multiple sets of limiting tubes are fixedly installed on the top of the mounting frame. A telescopic rod is slidably connected inside the limiting tube. A feeding frame with inclined sides is fixedly connected to the top of the telescopic rod. A second spring is fixedly connected between the feeding frame and the mounting frame and outside the limiting tube.

[0008] Furthermore, the receiving mechanism includes a receiving trolley, an inclined surface, a positioning column, a hinge seat, and a positioning claw. The inner wall of the receiving trolley has an inclined surface on one side, and a positioning column is fixedly connected to one side of the receiving trolley. The side wall of the mounting frame is rotatably connected to a positioning claw that is engaged with the outside of the positioning column through the hinge seat.

[0009] Furthermore, two sets of limiting rods are fixedly connected to one side of the receiving trolley, and the limiting rods are inserted into the mounting frame.

[0010] Furthermore, a cushioning pad made of sponge material is laid on the top of the feeding frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: After the material injection molding is completed, the driving cylinder pulls the moving mold and the fixed mold to separate. In this way, the material can be taken out from the moving mold by the stripping mechanism. Then the material will fall and be buffered by the buffer mechanism, thereby preventing the material from falling directly and causing damage. The subsequent material receiving mechanism can be fixedly set at the material feeding position of the buffer mechanism. Moreover, the material receiving mechanism can prevent the material from being over-stacking during collection and ensure that the material can be collected evenly. Attached Figure Description

[0014] 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.

[0015] Please see Figures 1-3 This utility model provides a technical solution: an injection mold for an engineering plastic pad block, including a mounting frame 1. Two sets of mounting plates 2 are fixedly mounted on the top of the mounting frame 1. A fixed mold 14 is fixedly mounted on one set of mounting plates 2. Multiple sets of sliding rods 3 are fixedly connected between the two sets of mounting plates 2. A movable mold 4 is slidably connected to the outside of the sliding rods 3. Two sets of driving cylinders 5 are fixedly mounted on the other set of mounting plates 2. The output end of the driving cylinder 5 is fixedly connected to the movable mold 4. The movable mold 4 is provided with a material ejection mechanism 6 for material ejection. A buffer mechanism 7 for material buffering is provided on the mounting frame 1 and between the movable mold 4 and the fixed mold 14. A material receiving mechanism 8 for preventing material accumulation is provided on the mounting frame 1.

[0016] After the material injection is completed, the drive cylinder 5 pulls the moving mold 4 and the fixed mold 14 to separate. The material can then be taken out from the moving mold 4 by the ejector mechanism 6. The material will then fall and be buffered by the buffer mechanism 7 to prevent the material from falling directly and causing damage. The receiving mechanism 8 is then fixedly set at the unloading position of the buffer mechanism 7. The receiving mechanism 8 can also prevent the material from being over-stacking during collection, ensuring that the material can be collected evenly.

[0017] Please see Figure 1 The stripping mechanism 6 includes stripping rods 9, connecting plate 10, first springs 11, connecting seat 12, and top seat 13. Multiple sets of stripping rods 9 are arranged through the moving mold 4. The connecting plate 10 is fixedly connected to one side of the stripping rods 9, and the connecting seat 12 is fixedly connected to one side of the connecting plate 10. The top seat 13 is fixedly connected to the mounting plate 2 at the position corresponding to the connecting seat 12. Multiple sets of first springs 11 are arranged between the moving mold 4 and the connecting plate 10.

[0018] When the moving mold 4 moves backward, the connecting seat 12 contacts the top seat 13. Then, as the moving mold 4 continues to move backward, multiple sets of stripper rods 9 can be used to eject the material after injection molding from the moving mold 4. The multiple sets of first springs 11 can fix the position of the connecting plate 10 and the stripper rods 9 during injection molding.

[0019] Please see Figures 1-3The buffer mechanism 7 includes a limiting tube 15, a telescopic rod 16, a feeding frame 17, and a second spring 18. Multiple sets of limiting tubes 15 are fixedly installed on the top of the mounting frame 1. The telescopic rod 16 is slidably connected inside the limiting tube 15. The feeding frame 17, which is inclined on both sides, is fixedly connected to the top of the telescopic rod 16. The second spring 18 is fixedly connected between the feeding frame 17 and the mounting frame 1 and outside the limiting tube 15. The top of the feeding frame 17 is covered with a buffer pad made of sponge material.

[0020] When the material falls, it will first come into contact with the feeding frame 17. The pressure on the feeding frame 17 can cause the telescopic rod 16 to move into the limiting tube 15. The second spring 18 can buffer the feeding frame 17. The buffered material on the feeding frame 17 can fall and be collected through the inclined surfaces on both sides. The cushioning pad made of sponge material can further buffer and protect the material.

[0021] Please see Figures 1-3 The receiving mechanism 8 includes a receiving trolley 19, an inclined surface 20, a positioning post 21, a hinge seat 22, and a positioning claw 23. The inner wall of the receiving trolley 19 has an inclined surface 20 on one side. The positioning post 21 is fixedly connected to one side of the receiving trolley 19. The side wall of the mounting frame 1 is rotatably connected to the positioning claw 23, which is engaged with the outside of the positioning post 21, through the hinge seat 22. Two sets of limiting rods 24 are fixedly connected to one side of the receiving trolley 19. The limiting rods 24 are inserted into the inside of the mounting frame 1.

[0022] When the receiving trolley 19 needs to collect materials, the limiting rod 24 on one side of the receiving trolley 19 is inserted into the mounting frame 1 for positioning. Then, the positioning claw 23 is pulled to rotate along the hinge seat 22, so that the positioning claw 23 can be engaged with the positioning post 21 for positioning. This can cooperate with the limiting rod 24 to prevent the receiving trolley 19 from shifting. The inclined surface 20 on the inner wall of the receiving trolley 19 can prevent excessive accumulation of materials during collection.

[0023] In use, firstly, after the material injection is completed, the drive cylinder 5 pulls the moving mold 4 and the fixed mold 14 to separate. This allows the ejector mechanism 6 to remove the material from the moving mold 4. The material then falls and is buffered by the buffer mechanism 7, preventing damage from direct drop. The receiving mechanism 8 is then fixed at the discharge position of the buffer mechanism 7. The receiving mechanism 8 prevents excessive stacking of material during collection, ensuring even material collection. As the moving mold 4 moves backward, the connecting seat 12 contacts the top seat 13. As the moving mold 4 continues to move backward, multiple sets of ejector rods 9 can eject the injection-molded material from the moving mold 4. Multiple sets of first springs 11 can fix the position of the connecting plate 10 and the ejector rods 9 during injection molding. When the material falls, it will first contact the feeding frame 17. The pressure on the feeding frame 17 will cause the telescopic rod 16 to move into the limiting tube 15. The second spring 18 can buffer the feeding frame 17. The buffered material on the feeding frame 17 can fall and be collected through the inclined surfaces on both sides. The cushioning pad made of sponge material can further buffer and protect the material. When the receiving trolley 19 needs to collect the material, the limiting rod 24 on one side of the receiving trolley 19 is inserted into the mounting frame 1 for positioning. Then, the positioning claw 23 is pulled to rotate along the hinge seat 22. This allows the positioning claw 23 to engage with the positioning post 21 for positioning. This can cooperate with the limiting rod 24 to prevent the receiving trolley 19 from shifting. The inclined surface 20 on the inner wall of the receiving trolley 19 can prevent the material from accumulating excessively during collection.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
