Description

Technical Field

[0001] The present invention relates to the technical field of rubber molding, in particular to a rubber molding mechanism. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a very small external force, and can return to its original shape after the external force is removed. Rubber molding is the process of using molds to shape rubber materials into specific components. This process involves applying heat and pressure to the rubber to form it into the shape of the mold cavity.

Through the arrangement of the blanking device and the extrusion device, when using the device, the blanking device can not only ensure that the molded rubber material is quickly taken out, but also can quickly replace molds of different shapes as needed to meet the production needs of different types of rubber products, improve work efficiency, have strong practicality, and have certain commercial value. The extrusion device is provided with a cylinder, which is pneumatically controlled to speed up the molding speed of the rubber material.

[0004] In rubber molding, high-temperature rubber materials are molded in the mold. Excessively high temperatures increase the difficulty of demolding. The above devices lack the corresponding workpiece demolding function. In existing demolding mechanisms, a person generally uses a handheld air gun to quickly blow air to cool the molded rubber part, and then manually removes it, which is labor-intensive and cumbersome. Some devices with demolding functions mostly use ejectors or other methods to eject the rubber part from the lower mold. This method is easy to penetrate weaker rubber parts during demolding, thereby causing damage to the rubber parts. Therefore, a rubber molding mechanism is proposed to solve the above problem.

A threaded adjusting rod 86 is rotatably connected to the insert plate 85. After the third motor 82 works, it drives the second threaded rod 81 to rotate. After the second threaded rod 81 rotates, it drives the control plate 83 to move, thereby realizing the horizontal movement of the mounting frame 14; The second threaded rod 81 passes through the control plate 83 and is threadedly connected to the control plate 83 . The threaded adjustment rod 86 extends out of the auxiliary plate 84 and is threadedly connected to the auxiliary plate 84 .

[0036] An upper mold 15 is provided on the inner side of the second U-shaped plate 4, and the mold clamping assembly 6 includes a top plate 61, and a second electric push rod 62 is fixedly connected to the top wall of the second U-shaped plate 4. One end of the second electric push rod 62 is fixedly connected to the top of the top plate 61, and the top of the top plate 61 is fixedly connected to a guide plate, which passes through the top wall of the second U-shaped plate 4. The top of the upper mold 15 is fitted with the top plate 61, and a movable frame 63 is slidably connected to the front side wall of the second U-shaped plate 4. Two threaded blocks 64 are slidably connected inside the movable frame 63. Two plug-in plates 65 are provided at the bottom of the upper mold 15, and the plug-in plates 65 match the auxiliary slots 9. A heat dissipation fan 66 is fixedly connected to the plug-in plates 65, and a positioning plate 67 is fixedly connected between the threaded block 64 and the plug-in plates 65. A third electric push rod 68 is fixedly connected to the bottom of the movable frame 63, and the third electric push rod 68 is fixedly connected to the top of the base plate 1. The guide plate limits the top plate 61 to ensure that it can be stably lifted and lowered vertically.

[0037] The movable frame 63 is internally rotatably connected to a first bidirectional threaded rod 69, which passes through the two threaded blocks 64 in sequence, and the first bidirectional threaded rod 69 and the threaded blocks 64 are connected by threads. A fourth motor 691 is fixedly connected to one side of the movable frame 63, and the fourth motor 691 is fixedly connected to one end of the first bidirectional threaded rod 69 through an output shaft. The threads at both ends of the first bidirectional threaded rod 69 have opposite directions, which can drive the two threaded blocks 64 to move toward or away from each other.

[0038] Two extension plates 692 are integrally formed on one side of the top plate 61. Two fixing plates 693 are provided between the two extension plates 692. The two fixing plates 693 pass through the two extension plates 692 respectively and extend into the interior of the top plate 61. Two mounting plates 694 are fixedly connected to the top of the upper mold 15. The mounting plates 694 pass through the top plate 61, and the two fixing plates 693 pass through the two mounting plates 694 respectively. After the mounting plates 694 pass through the top plate 61, the fixing plates 693 are controlled to pass through the mounting plates 694, so that the mounting plates 694 can be fixed to the top plate 61, completing the installation of the upper mold 15. A second bidirectional threaded rod 695 is rotatably connected between the two extension plates 692. The second bidirectional threaded rod 695 passes through the two fixed plates 693 in sequence, and the second bidirectional threaded rod 695 is respectively connected to the two fixed plates 693 through threads. The thread directions at both ends of the second bidirectional threaded rod 695 are opposite, which can drive the two fixed plates 693 to move toward or away from each other.

[0039] In actual operation, when the device is used, first, the device is connected to a power source. After the third motor 82 starts working, it drives the second threaded rod 81 to rotate. The second threaded rod 81 drives the control board 83 to move horizontally. The control board 83 drives the installation frame 14 to move. The installation frame 14 drives the lower mold 7 to move horizontally. After the lower mold 7 moves below the upper mold 15, it can be molded together with the upper mold 15 to perform the rubber molding operation. After the lower mold 7 is moved toward the first U-shaped plate 3, the material can be discharged or the molded rubber part can be taken out from the lower mold 7. After the high-temperature rubber raw materials are placed into different cavities 10 in turn, the lower mold 7 is controlled to move to the bottom of the upper mold 15, and then the second electric push rod 62 works to push the top plate 61 until the upper mold 15 and the lower mold 7 are closed, and the rubber raw materials can be shaped. During this period, if it is necessary to accelerate the molding speed of the rubber raw materials, the third electric push rod 68 works to pull the movable frame 63. It can be seen from the above connection relationship that at this time, the heat dissipation fan 66 follows the movable frame 63 to move up and down. When the heat dissipation fan 66 moves to the plug board 6 5 matches the height of the auxiliary groove 9, the fourth motor 691 starts to work and drives the first bidirectional threaded rod 69 to rotate. The first bidirectional threaded rod 69 drives the two threaded blocks 64 to move toward each other. The threaded blocks 64 drive the positioning plate 67 to move. The positioning plate 67 drives the plug-in plate 65 to move and insert it into the auxiliary groove 9. The heat dissipation fan 66 starts to blow air into the second through hole 13. Then, the air passes through the annular heat dissipation groove 11 and is discharged through the first through hole 12. This promotes the air flow inside the annular heat dissipation groove 11, thereby accelerating the cooling and molding speed of the rubber part. In this device, after the first electric push rod 591 is operated, it pushes the moving block 54 horizontally, and the moving block 54 mobilizes the bellows 56 to move, and the bellows 56 drives the wind hood 57 to move, thereby adjusting the horizontal position of the wind hood 57. After the first motor 59 is operated, it drives the first threaded rod 51. After the first threaded rod 51 rotates, it drives the connecting block 53 to perform lifting and lowering adjustment. The connecting block 53 drives the lifting plate 52 to move vertically. It can be seen from the above connection relationship that the height of the wind hood 57 can be adjusted in this way. After the second motor 595 is operated, it drives the gear 596 to rotate, the gear 596 drives the ring gear 597 to rotate, the ring gear 597 drives the ring plate 594 to rotate, and the ring plate 594 drives the lifting plate 52 to swing and rotate with the connecting block 53 as the axis, thereby quickly adjusting the direction of the wind hood 57. After the above rubber parts are formed, similar operations are repeated to control the upper mold 15 to move upward and further control the two plug-in plates 65 to move away from the auxiliary groove 9, and after the plug-in plates 65 are controlled to move upward to be higher than the lower mold 7, the lower mold 7 is controlled to move toward the first U-shaped plate 3. Subsequently, through the above steps of controlling the position of the wind hood 57, the wind hood 57 can be controlled to stay at the top of different cavities 10 in turn. The high-pressure fan 55 generates airflow to directly cool the rubber parts in the cavity 10. During this period, a part of the airflow enters the annular The heat dissipation groove 11 is used to cool the periphery of the cavity 10, which is beneficial to the rapid cooling of the rubber parts in the cavity 10. When the rubber parts are fully cooled, the high-pressure fan 55 changes from exhaust to suction, prompting the rubber parts to be sucked upward into the air cover 57 for adsorption demoulding. When the rubber parts are sucked into the air cover 57, the mesh plate 58 acts as a barrier, prompting the rubber parts to stay in the air cover 57. After the rubber parts are demoulded and sucked into the air cover 57, the above steps of controlling the rotation of the lifting plate 52 can be used to drop the rubber parts in different areas, thereby feeding the materials in the direction specified by the user. Finally, the upper mold 15 and the lower mold 7 in this device can be flexibly disassembled and replaced. By rotating the threaded adjustment rod 86, the threaded adjustment rod 86 drives the insert plate 85 to move. When the insert plate 85 moves away from the lower mold 7, the lower mold 7 can be taken out of the mounting frame 14 to complete the disassembly. By rotating the second bidirectional threaded rod 695, the second bidirectional threaded rod 695 drives the two fixed plates 693 to move away from each other to leave the mounting plate 694. The mounting plate 694 can be pulled out from the top plate 61 to realize the disassembly of the upper mold 15. Based on the above operations, the loading and unloading functions of the upper mold 15 and the lower mold 7 can be quickly completed, which is conducive to replacing different molds to meet the molding requirements of rubber parts of different shapes.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
