Description

Technical Field

[0001] This utility model relates to the field of vulcanization molding technology, and in particular to molding dies used in the production of paper feed rollers. Background Technology

[0002] As a key transmission component in office equipment and printing machinery, the performance of paper feed rollers directly affects the accuracy and stability of paper feeding. Currently, paper feed rollers are mainly manufactured using a hot-press molding process with rubber or polymer materials. After molding, the paper feed rollers require manual handling or auxiliary tools for removal, resulting in low operating efficiency and susceptibility to product damage.

[0003] Traditional forming dies used in paper feed roller production typically employ a fixed structure, including a die plate, a die cavity, and an ejection mechanism. The die plate is maintained at a constant temperature by a heating unit. After the material is formed under pressure within the die cavity, demolding is achieved via a mechanical ejector pin or manual operation. Some equipment may be equipped with a simple air-cooling system, but the fan is usually fixed in place, and the cooling direction is not adjustable, resulting in limited cooling efficiency. The ejection mechanism often relies on springs or pneumatic devices to drive the ejector pins, resulting in low precision in stroke and force control, which can easily cause product deformation or surface damage during demolding.

[0004] However, the forming dies used in traditional paper feed roller production generate high temperatures during the forming process, making it difficult to remove the formed rollers directly. Operators must wait for them to cool down, reducing production efficiency and increasing the risk of product damage due to improper handling. The fixed cooling system's inability to adjust the airflow direction further exacerbates the difficulty in removing the paper feed rollers. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a molding die for the production of paper feed rollers, which aims to improve the problem that the temperature of the molding die used in the production of traditional paper feed rollers is too high during the forming process, making it inconvenient to remove.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a forming mold for producing paper feed rollers, including a base, a control console fixedly connected to the top of the base, a hydraulic platform fixedly connected to the top of the base, a connecting plate three fixedly connected to the output end of the hydraulic platform, a table surface fixedly connected to the top of the connecting plate three, a limiting plate fixedly connected to the top of the connecting plate three, a limiter fixedly connected to one side of the limiting plate, a connecting block one fixedly connected to one end of the limiter, and a cooling component provided on the top of the connecting block one; The cooling assembly includes an inner shell, the bottom of which is fixedly connected to the top of a connecting block. An outer shell is fitted onto the outer wall of the inner shell. A connector is fixedly connected to the top of the outer shell. A fan is rotatably connected to the top of the connector. A pin is slidably connected inside the outer shell, and the pin is slidably connected inside the inner shell.

[0007] As a further description of the above technical solution: A connecting plate two is fixedly connected to the outer wall of the hydraulic platform. Limiting rods two are slidably connected to both ends of the connecting plate two. The bottom of the limiting rods two is fixedly connected to the top of the base, and a top platform is fixedly connected to the top of the limiting rods two.

[0008] As a further description of the above technical solution: A connecting block two is fixedly connected to one side of the base, a connecting rod is fixedly connected to the top of the connecting block two, an electric slide rail is fixedly connected to the top of the connecting rod, a push plate is fixedly connected to the output end of the electric slide rail, and a mold plate is fixedly connected to one end of the push plate.

[0009] As a further description of the above technical solution: The mold plate is fixedly connected to the top of the mold plate, and a mold piece is slidably connected inside the lower mold.

[0010] As a further description of the above technical solution: The bottom of the limiting plate is fixedly connected to a limiting rod, and the bottom of the limiting rod is fixedly connected to a connecting plate.

[0011] As a further description of the above technical solution: An electric push rod is fixedly connected to the bottom of the connecting plate, and a lifting plate is fixedly connected to the output end of the electric push rod. The two ends of the lifting plate are slidably connected to the outer wall of the limiting rod.

[0012] As a further description of the above technical solution: A pin is fixedly connected to the top of the lifting plate, and a limit rod is fixedly connected to the top of the lifting plate.

[0013] As a further description of the above technical solution: The top of the limiting rod is fixedly connected to a lifting plate, and the top of the lifting plate is provided with a lifting rod, one end of which is fixedly connected to an upper mold.

[0014] This utility model has the following beneficial effects: 1. In this utility model, firstly, the connecting block is connected to one side of the mold plate by a limiter. The top of the connecting block is fixed with an inner shell, and an outer shell is fitted on its outer wall. The inner shell and the outer shell are connected by a pin. Secondly, a fan is installed on the top of the outer shell, and the fan can rotate on the top of the outer shell through a connector, thereby adjusting the direction of the cooling air blown by the fan. This achieves the effect of cooling the newly formed paper feed roller, solving the problem that the forming mold used in the traditional paper feed roller production is too hot during the paper feed roller forming process and is inconvenient to remove. This improves the comfort of operating the forming mold used in the paper feed roller production process.

[0015] 2. In this utility model, the lifting plate is pushed upward by the electric push rod, which in turn pushes the ejector pin upward, so that the ejector pin passes through the lifting plate and its top end contacts the bottom of the mold plate. After the paper-feeding roller is formed, the paper-feeding roller is ejected by the mold plate through the electric push rod, so as to quickly demold the formed paper-feeding roller. This solves the inconvenience of demolding the forming mold used in the production of traditional paper-feeding rollers and improves the practicality of the forming mold used in the production of paper-feeding rollers.

An outer shell 20 is fitted onto the outer wall of the inner shell 19, and a connector 21 is fixedly connected to the top of the outer shell 20. A fan 7 is rotatably connected to the top of the connector 21. The outer shell 20 is fitted onto the outer wall of the inner shell 19 and can move up and down along the inner shell 19 to adjust the height of the fan 7. A pin 32 is slidably connected inside the outer shell 20 and is slidably connected inside the inner shell 19. Through the connection of the pin 32, the position of the outer shell 20 relative to the inner shell 19 can be fixed, thereby fixing the height of the fan 7 and allowing the fan 7 to cool the formed paper feeding roller.

[0021] Reference Figures 1-6A connecting plate 25 is fixedly connected to the outer wall of the hydraulic table 24. Limiting rods 11 are slidably connected to both ends of the connecting plate 25. The bottom of the limiting rods 11 is fixedly connected to the top of the base 1. A top platform 10 is fixedly connected to the top of the limiting rods 11. The hydraulic table 24 lifts the connecting plate 29 and the table surface 30 upwards. Through the cooperation of the top platform 10, the mold of the paper-feeding roller is squeezed, thereby providing pressure for the vulcanization and forming of the paper-feeding roller. A connecting block 26 is fixedly connected to one side of the base 1. A connecting rod 27 is fixedly connected to the top of the connecting block 26. An electric slide rail 28 is fixedly connected to the top of the connecting rod 27. A push plate 31 is fixedly connected to the output end of the electric slide rail 28. A mold plate 18 is fixedly connected to one end of the push plate 31. The electric slide rail 28 is connected to one side of the base 1 through the connecting rod 27 and the connecting block 26. The push plate 31 drives the mold plate 18 to move, so as to drag the mold plate 18 into or out of the extrusion area. A lower mold 15 is fixedly connected to the top of the mold plate 18. A mold piece 22 is slidably connected inside the lower mold 15. The bottom of the limiting plate 16 is fixedly connected to the lower mold 18. A limiting rod 4 is fixedly connected to the bottom of the limiting rod 4. A connecting plate 3 is fixedly connected to the bottom of the connecting plate 3. An electric push rod 2 is fixedly connected to the output end of the electric push rod 2. A lifting plate 5 is fixedly connected to both ends of the lifting plate 5 on the outer wall of the limiting rod 4. An ejector pin 13 is fixedly connected to the top of the lifting plate 5. The electric push rod 2 pushes the lifting plate 5 upward, causing the ejector pin 13 to pass through the mold plate 18 and abut against the bottom of the mold piece 22. The electric push rod 2 continues to push the ejector pin 13 upward, causing the mold piece 22 to press against the bottom of the lower mold 15. The formed paper-feeding roller is ejected for easy collection by workers. The top of the lifting plate 5 is fixedly connected to the limit rod 23, and the top of the limit rod 23 is fixedly connected to the lifting plate 8. The top of the lifting plate 8 is provided with the lifting rod 14, and one end of the lifting rod 14 is fixedly connected to the upper mold 9. At the same time, the electric push rod 2 pushes the lifting plate 5 to move upward, which in turn drives the limit rod 23 and the lifting plate 8 to move upward, which in turn pushes the lifting rod 14 and drives the upper mold 9 to move upward, so that the upper mold 9 is separated from the lower mold 15, which makes it easier for the ejector pin 13 to drive the mold plate 22 to eject the paper-feeding roller.

[0022] Working principle: Raw material is placed in the lower mold 15. The electric push rod 2 drives the lifting plate 5, which in turn drives the limit rod 23 and the lifting plate 8 to move downward, thereby lowering the upper mold 9 until it is placed on the lower mold 15. The electric slide rail 28 controls the push plate 31 to move backward, which in turn drives the mold plate 18, which in turn drives the lower mold 15 and the upper mold 9 to the top of the table 30. The hydraulic table 24 is activated, which pushes the connecting plate 29 and drives the table 30 to move upward. With the cooperation of the top table 10, the upper mold 9 and the lower mold 15 are squeezed, thereby providing pressure for the vulcanization molding of the paper rolling wheel.

[0023] After a certain time has elapsed, the hydraulic table 24 moves the connecting plate 39 and the table surface 30 downwards. Then, the electric slide rail 28 controls the push plate 31 to push out the mold plate 18 and drive the lower mold 15 and the upper mold 9. The electric push rod 2 is activated, which drives the lifting plate 5 to move upwards, thereby driving the limit rod 323 and the lifting plate 8 to move upwards and opening the upper mold 9. At the same time, the lifting plate 5 drives the ejector pin 13 to pass through the mold plate 18 and then abut against the bottom of the mold piece 22, thereby pushing the mold piece 22 to push out the formed paper-feeding roller. While the mold piece 22 pushes out the paper-feeding roller, the fan 7, whose height is adjusted by the pin 32, the inner shell 19 and the outer shell 20, cools down the newly formed paper-feeding roller, making it easier for the worker to remove the paper-feeding roller from the mold.
