Description

Magnetic quick-change rubber mold fixing assembly Technical Field

[0001] This utility model relates to the field of rubber production mold technology, and in particular to a magnetic quick-change rubber mold fixing component. Background Technology

[0002] A rubber mold is a tool used to mold rubber products. Through specific cavities and structures, it molds fluid rubber materials into the required shapes and sizes under certain temperature and pressure conditions. During the molding process of rubber products, key components of the mold cavity and core will be displaced and deformed, thus requiring additional fixing to stabilize the mold and ensure that the mold maintains the correct relative position and structural stability during use.

[0003] Magnetic quick-change rubber mold fixing components are devices used to fix rubber molds. They utilize magnetic force to achieve rapid mold replacement and fixation. Under the action of magnetic force, mold parts can be quickly and accurately attracted and fixed together, enabling rapid mold assembly. When it is necessary to replace the mold or repair and maintain it, the mold parts can be easily separated by controlling the magnetic force of the magnet, completing rapid disassembly. However, in existing magnetic quick-change rubber mold fixing components, the magnetic fixing components rely on magnetic force for rapid attraction and fixation and lack a buffer design. When the mold parts approach each other and are quickly attracted, there is no buffer structure to absorb and disperse kinetic energy. Moreover, in the long-term frequent use, it will cause wear and dents on the mold surface, affecting the accuracy of the mold and the attraction stability of the fixing component, reducing the molding quality of the mold and the service life of the fixing component, and ultimately affecting the production efficiency and quality of rubber products.

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.

[0031] Referring to Figures 1, 3, and 4, one embodiment of this utility model provides a magnetic quick-change rubber mold fixing assembly, including a base 1. A lower mold 3 is fixedly connected to the top of the outer wall of the base 1. A magnetic suction plate 4 is fixedly connected to the top of the outer wall of the lower mold 3.

A fixing plate is threadedly connected to the top of the outer wall of the threaded rod 9. 12. A movable frame 2 8 is rotatably connected to the bottom of the outer wall of the threaded rod 9. The movable frame 2 8 is slidably connected to the middle of the outer wall of the rotating rod 5. A spring 7 is fixedly connected to the middle of the outer wall of the rotating rod 5 and the fixed rod 1 6. A handle 11 is fixedly connected to the top of the outer wall of the threaded rod 9. An upper mold 13 is fixedly connected to the bottom of the outer wall of the movable frame 2 8. A fixing mechanism 2 is fixedly connected to the top of the outer wall of the base 1. The fixing mechanism 2 is used to clamp the fixing component. Baffles 14 are fixedly connected to the front and rear sides of the outer wall of the lower mold 3. Screws 15 are threadedly connected to the outer wall of the baffles 14 at equal intervals.

[0032] Specifically, the fixed frame 201 is mounted on the base 1 as the main support. Its groove 202 can place and position components, providing stable space. The rotating shaft 203 connects the fixed frame 201 and the movable frame 204, allowing it to rotate around the rotating shaft 203, facilitating the installation, disassembly, and adjustment of components. The handle 205 passes through the fixed frame 201, making it convenient for the operator to control the movable frame 204. The pin 206 slides on the outer wall of the handle 205 to fix the movable frame 204, preventing accidental rotation and ensuring the stability of the mechanism. When adjustment is needed, the pin can be pulled out. The fixing mechanism 2 at the top of the base 1 serves as the core for supporting and clamping the fixed components. It can stably clamp the components through a specific mechanical structure, ensuring that the components are fixed in position and do not shift during operation. The baffles 14 on the front and rear sides of the outer wall of the lower mold 3 can be flexibly adjusted for tightness by means of the screws 15 evenly distributed on their outer walls. On the one hand, it can strengthen the connection between the baffles 14 and the lower mold 3. On the other hand, it can restrict and guide the position of materials and parts, working together with the fixing mechanism 2 to ensure the stability and accuracy of the equipment operation.

[0033] Referring to Figures 1, 2, and 5, the fixing mechanism 2 includes a fixing frame 201, which is fixedly connected to the top of the outer wall of the base 1. A groove 202 is provided in the middle of the inner wall of the fixing frame 201. A rotating shaft 203 is rotatably connected to the left end of the outer wall of the fixing frame 201. A movable frame 204 is fixedly connected to one side of the outer wall of the rotating shaft 203. A handle 205 passes through the right side of the inner wall of the fixing frame 201. A pin 206 is slidably connected to the front and rear sides of the outer wall of the handle 205. A second handle 17 is fixedly connected to both the left and right sides of the outer wall of the lower mold 3. Limiting posts 16 are fixedly connected to the four corners of the top of the lower mold 3. Multiple sliding grooves 18 are provided on the top of the outer wall of the base 1. A limiting plate 19 is slidably connected to the middle of the inner wall of the sliding groove 18.

[0034] Specifically, the component consists of a base 1, a lower mold 3 fixed thereon, and a magnetic plate 4. The magnetic plate 4 uses magnetic force to quickly attract the part to be processed, achieving rapid positioning. The rotating rod 5 serves as the fulcrum of the transmission structure, connecting to the top left side of the base 1. Rotating the handle 11 drives the threaded rod 9 to rotate, causing the fixed plate 12 to move axially. At the same time, the moving frame 8 slides up and down and remains stable. The upper mold 13 moves with the moving frame 8, realizing the opening and closing of the mold. The first fixed rod 6 and the second fixed rod 10 form a frame to support the threaded rod 9. The spring 7 is located between the rotating rod 5 and the first fixed rod 6, serving as a buffer. The lower mold 3 has a resetting function to ensure smooth mold opening and closing and prevent positional deviation. The handles 17 are fixedly connected to the left and right sides of the outer wall for easy manual replacement and operation. The limiting posts 16 fixed at the four corners of the top of the lower mold 3 can play a positioning and guiding role during operation to ensure accurate cooperation with other components. The multiple sliding grooves 18 opened on the top of the base 1 provide sliding tracks for the limiting plate 19. The limiting plate 19 slides in the middle of the inner wall of the sliding groove 18. By adjusting its position, the lower mold 3 can be limited, fixed and adjusted to meet different working needs.

[0035] Referring to Figures 1, 2, and 3, a rotating shaft 21 is rotatably mounted at the bottom center of the rotating rod 5. A bolt 20 is threadedly connected to one side of the outer wall of the rotating shaft 21. A sliding rod 22 passes through the middle left and right sides of the fixed rod 10 and the movable frame 8. Nuts 23 are threadedly connected to the upper and lower ends of the outer wall of the sliding rod 22. A connecting plate 24 is fixedly connected to the middle of the inner wall of the handle 11. Screws 25 are threadedly connected to both sides of the outer wall of the connecting plate 24.

[0036] Specifically, the rotating rod 5 can rotate flexibly through the rotating shaft 21 connected to the middle of its bottom end. The bolt 20 on one side of the outer wall of the rotating shaft 21 can be tightened to fix it, which is used to adjust or fix the rotation angle and position of the rotating rod 5, ensuring its stable operation under specific working conditions. The sliding rod 22 that passes through the middle of the fixed rod 10 and the moving frame 8 provides a guide for their movement. The nuts 23 at the upper and lower ends of the outer wall of the sliding rod 22 can be tightened or loosened to restrict or allow the fixed rod 10 and the moving frame 8 to slide on the sliding rod 22, thereby adjusting and fixing their relative positions to meet the needs of different working scenarios for the spacing and position of components. The connecting plate 24 fixedly connected to the middle of the inner wall of the handle 11 serves to connect the handle 11 with other components. The screws 25 on both sides of the outer wall of the connecting plate 24 can securely connect the connecting plate 24 with other components. By rotating the handle 11, the connecting plate 24 can be driven, thereby realizing the control or transmission of related components.

[0037] Working principle: This component is based on base 1, with lower mold 3 fixed to the top of base 1. Magnetic plate 4 on lower mold 3 can quickly attract the rubber parts to be processed using magnetic force, achieving rapid installation and positioning. Rotating rod 5 is rotatably connected to the top left side of base 1, serving as a crucial fulcrum for the entire mechanical transmission structure. When the handle 11 is rotated, the threaded rod 9, fixedly connected to the handle 11, rotates accordingly. Since the threaded rod 9 is threadedly connected to the fixed plate 12, the rotating threaded rod 9 drives the fixed plate 12 to move up and down along its axial direction. Simultaneously, the movable frame 8, rotatably connected to the bottom of the threaded rod 9, also slides up and down due to the rotation of the threaded rod 9. The moving connection is located in the middle of the rotating rod 5 to ensure its stability of movement. The upper mold 13, which is fixed at the bottom of the moving frame 2 8, will move closer to or away from the lower mold 3 as the moving frame 2 8 moves, realizing the opening and closing action of the mold. The frame structure composed of the fixed rod 1 6 and the fixed rod 2 10 provides installation and support for the threaded rod 9 component. The spring 7 fixed between the rotating rod 5 and the fixed rod 1 6 plays a buffering and restoring role. During the opening and closing of the mold, the spring 7 absorbs and releases energy to assist the upper mold 13 to move smoothly. At the same time, after the opening and closing action is completed, the structure remains stable to prevent the mold position from shifting due to external forces, thus realizing convenient mold replacement.

[0038] The fixed frame 201 is fixed to the top of the base 1, serving as the main support for the entire structure. The groove 202 in the middle of its inner wall can be used to accommodate and position related components, providing a stable placement space. The rotating shaft 203 rotatably connected to the left end of the outer wall of the fixed frame 201 allows the movable frame 204 fixed to one side of its outer wall to rotate around the rotating shaft 203, realizing the position change or opening and closing of the movable frame 204. This facilitates the installation, disassembly, and adjustment of components placed in the groove 202. The handle 205 passes through the right side of the inner wall of the fixed frame 201. The operator can conveniently control the rotation of the movable frame 204 by holding the handle 205. The pins 206 slidably connected to the front and rear sides of the outer wall of the handle 205 serve to fix and limit the movement. When the movable frame 204 rotates to the appropriate position, the sliding pins 206 are inserted into the corresponding structure to fix the movable frame 204, preventing it from rotating arbitrarily and ensuring that the mechanism is in a stable working state. When it is necessary to readjust the position of the movable frame 204, the pins 206 can be pulled out to release the restriction.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
