Description

Technical Field

[0001] This utility model relates to the field of injection molding product processing technology, and in particular to a punching device for injection molding product processing. Background Technology

[0002] Injection molded parts refer to a general term for various injection-molded products produced by injection molding machines, including various packaging materials and components. Due to its advantages such as high production efficiency and ease of automation, injection molding technology is widely used in the production of various packaging components and parts. Since the products produced by injection molding are not the final products, they need to be processed by punching out unwanted injection molding waste to retain the desired injection molded products. However, existing punching fixtures produce products with burrs, cracks, and other defects, making them unsuitable for production requirements and often necessitating further processing, increasing production costs and reducing overall production efficiency. Furthermore, existing injection molding part punching fixtures still have certain problems in use: For example, an automatic punching fixture for injection molded parts, disclosed in CN103419248A, has the following technical solution: it is used to punch injection molded parts to form injection molded products and injection waste. The automatic punching fixture includes a punching mechanism, a control device for controlling the punching mechanism, and a frame for supporting the punching mechanism and the control device. The punching mechanism includes: a tool assembly, including multiple punching tools for punching injection molded parts; a punching plate assembly, including a punching plate for fixing and installing multiple punching tools and multiple punching guide rods for guiding and connecting the punching plate; a punching plate feeding device, used to drive the punching plate to slide along the punching guide rods according to the control command of the control device; and a support platform, used to support injection molded parts and provided with a discharge cutout that allows the injection molded product to exit. However, existing automatic punching fixtures for injection molded parts cannot recycle injection waste during use, requiring manual removal of waste, which is time-consuming and labor-intensive.

The roller 12 and the hypotenuse of the movable plate 17 are in contact with each other. A baffle 18 is fixedly connected to the right side of the movable plate 17. The two movable plates 17 are located on the front and rear sides of the workbench 1, respectively. A connecting frame 19 is fixedly connected to the side of the movable plate 17 away from the workbench 1. The cross-section of the connecting frame 19 is L-shaped. The connecting frame 19 is fixedly connected to the mounting plate 8.

[0017] In the above embodiment, the injection molded product is placed on top of the mold 3, and then the hydraulic rod 6 is controlled by an external power supply. The hydraulic rod 6 drives the mounting plate 8 and the punching plate 9 to move downward through the transmission rod 7, and the punching plate 9 punches the injection molded product.

[0018] After the punching plate 9 completes one punching, the external power supply controls the hydraulic rod 6 to work. The hydraulic rod 6 drives the mounting plate 8 and the punching plate 9 to move upward through the transmission rod 7. The mounting plate 8 drives the movable plate 17 to move upward through the connecting frame 19. When the movable plate 17 moves upward, the horizontal plate 10 drives the roller 12 to roll on the inclined surface of the movable plate 17. At the same time, the horizontal plate 10 moves to the right. The horizontal plate 10 drives the cylinder 14 to move on the outer edge of the limit rod 15 through the connecting plate 13. When the horizontal plate 10 moves, the elastic rope 20 is stretched. When the horizontal plate 10 moves, it drives the brush 11 to move. The brush 11 pushes the punched waste into the waste box 2. Example

[0019] Please see Figure 7The left side of the horizontal plate 10 is in contact with the right side of the support plate 5. An elastic rope 20 is fixedly connected to the left side of the horizontal plate 10. The elastic rope 20 is in a taut state. A groove 23 is provided on the top of the workbench 1 near the left side. A fixed pulley 21 is fixedly connected to the inner cavity of the groove 23. The fixed pulley 21 matches the elastic rope 20. A fixing block 22 is fixedly connected to the bottom end of the elastic rope 20. The fixing block 22 is fixedly connected to the side wall of the workbench 1.

[0020] In the above embodiment, when the next punching operation is carried out, the external power supply controls the hydraulic rod 6 to move the mounting plate 8 and the punching plate 9 downward. The mounting plate 8 drives the movable plate 17 to move downward through the connecting frame 19. The horizontal plate 10 moves to the left under the action of the elastic rope 20. The horizontal plate 10 moves to the left until it is in contact with the right side of the support plate 5. At this time, the horizontal plate 10 is reset and does not affect the punching operation.

[0021] Working principle: This utility model is a punching device for processing injection molded products. During use, the injection molded product is placed on top of the mold 3, and then the hydraulic rod 6 is controlled by an external power supply. The hydraulic rod 6 drives the mounting plate 8 and the punching plate 9 to move downward through the transmission rod 7. The punching plate 9 punches the injection molded product.

[0022] After the punching plate 9 completes one punching operation, the external power supply controls the hydraulic rod 6 to work. The hydraulic rod 6 drives the mounting plate 8 and the punching plate 9 to move upward through the transmission rod 7. The mounting plate 8 drives the movable plate 17 to move upward through the connecting frame 19. When the movable plate 17 moves upward, the horizontal plate 10 drives the roller 12 to roll on the inclined surface of the movable plate 17. At the same time, the horizontal plate 10 moves to the right. The horizontal plate 10 drives the cylinder 14 to move on the outer edge of the limit rod 15 through the connecting plate 13. When the horizontal plate 10 moves, the elastic rope 2 is stretched. 0. When the horizontal plate 10 moves, it drives the brush 11 to move. The brush 11 pushes the punched waste into the waste box 2. When the next punching operation is carried out, the external power supply controls the hydraulic rod 6 to work and drive the mounting plate 8 and the punching plate 9 to move downward. The mounting plate 8 drives the movable plate 17 to move downward through the connecting frame 19. The horizontal plate 10 moves to the left under the action of the elastic rope 20. The horizontal plate 10 moves to the left until it is in contact with the right side of the support plate 5. At this time, the horizontal plate 10 is reset and does not affect the punching operation.

[0023] When the device uses the hydraulic rod 6 to lift the mounting plate 8, it can lift and reset the punching plate 9, and also move the horizontal plate 10 to the right, achieving two goals at once. When the horizontal plate 10 moves to the right, it pushes the punched waste into the waste box 2, eliminating the need for manual waste cleaning and greatly saving labor.

[0024] By setting the elastic rope 20, when the punching plate 9 is moved down by the hydraulic rod 6 for punching, the horizontal plate 10 moves to the left under the action of the elastic rope 20. The horizontal plate 10 moves to the left until it is in contact with the right side of the support plate 5, so that the horizontal plate 10 is reset and the horizontal plate 10 is prevented from affecting the punching operation.
