[0028] The utility model provides a mold shifting mechanism for a rubber injection machine.

[0029] Please refer to Figures 1 to 3 In one embodiment of the utility model, a mold shifting mechanism for a rubber injection machine is provided, the rubber injection machine is provided with a mold locking cylinder 10, the mold locking cylinder 10 is used to drive the template to perform mold opening and closing actions, and the mold shifting mechanism of the rubber injection machine includes:

[0030] The mold transporting slide plate 20 is used to carry and move the mold;

[0031] A floating pallet 30, on which the mold transporting slide plate 20 is disposed, and the floating pallet 30 is provided with a mold lifter 40, which can drive the floating pallet 30 to move upward;

[0032] When the rubber injection machine opens the mold, the mold locking cylinder 10 drives the mold lifter 40 to lift up the floating support plate 30 .

[0033] The utility model application discloses a mold moving mechanism for a rubber injection machine. During use, a mold transporting slide plate 20 can be used to carry and move the mold. When the mold locking cylinder 10 drives the mold lifter 40 to rise, since at least part of the top of the mold lifter 40 can abut against the mold transporting slide plate 20, the mold lifter 40 lifts the mold transporting slide plate 20. It can be understood that the mold lifter 40 is used to lift the mold placed on the mold transporting slide plate 20 to a certain distance, so that the position of the mold can be slightly adjusted without manual handling, thereby improving the efficiency and accuracy of mold replacement, reducing the labor intensity and safety risks of operators, so that the mold transporting slide plate 20 can be horizontally slidably arranged on the upper surface of the floating pallet 30. When the mold transporting slide plate 20 slides to the top away from the floating pallet 30, the mold transporting slide plate 20 does not apply a force to the floating pallet 30 at this time, and the mold lifter 40 is not subjected to the force applied by the floating pallet 30. The application uses the linkage design of the integrated clamping cylinder 10 and the mold lifter 40 to quickly open the mold after the injection process is completed. There is no need for additional waiting time to separate and transport the mold. The mold lifter 40 directly drives the floating support plate 30 to move upward to achieve rapid opening and closing of the mold, significantly speeding up the production cycle and improving the overall production efficiency. The design of the mold transport slide 20 allows the mold to be stably supported during the movement. Combined with the precise control of the mold lifter 40, it can achieve fine-tuning positioning of the mold, ensure high-precision alignment each time the mold is closed, reduce mold wear, and improve product quality. Therefore, the common setting of the floating support plate 30 and the mold lifter 40 allows the mold transport slide 20 to be smoother during the sliding process. Even when the mold is completely lifted and out of contact with the floating support plate 30, it can ensure the balance and stability of the entire system and avoid unnecessary vibration or shaking, which has a positive effect on protecting the mold from damage and extending its service life.

[0034] Please refer to Figures 1 to 3 In one embodiment of the utility model, the mold lifter 40 includes a movable pressure rod 41 , one end of the movable pressure rod 41 abuts against the floating support plate 30 , and the other end of the movable pressure rod 41 abuts against the clamping cylinder 10 .

[0035] When the mold opens to the bottom, the mold transport slide plate 20 slides to the top away from the floating support plate 30, and the movable pressure rod 41 contacts and limits the clamping cylinder 10 of the rubber machine. This design cleverly utilizes the force in the clamping process. This direct drive method reduces the intermediate links, improves the response speed and control accuracy, and ensures the synchronization and accuracy of the mold lifting and lowering actions. At the same time, by adjusting the length of the movable pressure rod 41 or the tightness of the clamping, the driving force and response characteristics of the system can be fine-tuned to meet the needs of different working conditions. In addition, the locking mechanism of the clamping cylinder 10 provides safety protection for mold replacement and maintenance operations.

[0036] Please refer to Figures 1 to 3 In one embodiment of the utility model, the mold lifter 40 also includes a roller 42, the floating support plate 30 is provided with a slot hole for accommodating the roller 42, the roller 42 passes through the slot hole, and a groove is provided at the bottom of the mold transporting slide plate 20, and the roller 42 extends into the groove to limit the movement of the mold transporting slide plate 20.

[0037] The roller 42 is arranged on the roller 42 to ensure that the roller 42 is firmly installed. In addition, the upper surface of the roller 42 is at least partially higher than the upper surface of the groove, which can ensure that the upper end surface of the roller 42 can abut against the lower end surface of the mold transporting slide plate 20. Then, the rolling contact between the roller 42 and the mold transporting slide plate 20 is smaller than the sliding contact friction, which can reduce the movement resistance and improve the smoothness of the movement and the positioning accuracy. That is, the roller 42 is used to reduce the friction between the lower end surface of the mold transporting slide plate 20 and the upper end surface of the floating pallet 30, so that the mold transporting slide plate 20 can slide on the upper end surface of the floating pallet 30. It can be understood that the roller 42 not only reduces the friction between the lower end surface of the mold transporting slide plate 20 and the upper end surface of the floating pallet 30, but also ensures the guiding accuracy of the floating pallet 30 during the up and down movement through the design that its highest end contacts the mold transporting slide plate 20, further ensuring the smooth lifting and lowering of the floating pallet 30. In this embodiment, there are multiple grooves and multiple rollers 42, and the multiple rollers correspond to the multiple grooves one by one. In addition, the roller structure is simple and easy to replace. When a roller is worn or damaged, it can be quickly replaced without affecting the operation of the entire system, thereby reducing maintenance costs and downtime.

[0038] Please refer to Figures 1 to 3In one embodiment of the utility model, a mounting seat 43 is provided at one end of the movable pressure rod 41, and the roller 42 is rotatably mounted on the mounting seat 43. The mold lifter 40 also includes an elastic member 44, one end of which is sleeved on the movable pressure rod 41, and the other end of the elastic member 44 abuts against the floating support plate 30.

[0039] When the mold is opened to the bottom, the mold transport slide plate 20 slides to the top away from the floating support plate 30. In order to prevent the elastic member 44 from continuing to deform upward, the movable pressure rod 41 contacts and limits the clamping cylinder 10 of the rubber machine. This design cleverly utilizes the force in the clamping process. By compressing the elastic member 44, the elastic member 44 is prevented from continuing to deform upward, protecting the spring from excessive stretching or compression, and ensuring the stable operation and long service life of the elastic member 44. It can be understood that the present application can achieve direct and precise control of the deformation of the elastic member 44 by connecting the movable pressure rod 41 to directly connect the elastic member 44 and the clamping cylinder 10. This direct drive method reduces the intermediate links, improves the response speed and control accuracy, and ensures the synchronization and accuracy of the lifting and lowering actions of the mold. At the same time, by adjusting the length of the connecting movable rod or the tightness of the clamping, the driving force and response characteristics of the system can be fine-tuned to meet the needs under different working conditions. Moreover, the locking mechanism of the clamping cylinder 10 provides a safety guarantee for mold replacement and maintenance operations, prevents accidental expansion and contraction of the elastic member 44 under unexpected circumstances, reduces potential safety hazards during operation, and ensures production safety.

[0040] Please refer to Figures 1 to 3 In one embodiment of the present invention, the elastic member 44 is a rectangular spring.

[0041] In the present application, preferably, the elastic member 44 is a rectangular spring. As an elastic reset element, the rectangular spring provides the necessary support and resilience for the floating beam through its elastic movement up and down. The rectangular spring is composed of a plurality of balanced steel strips and can withstand greater loads and deformations. Compared with traditional springs, the rectangular spring has a stronger load-bearing capacity and can also greatly reduce the probability of spring failure.

[0042] Please refer to Figures 1 to 3 In one embodiment of the utility model, the mold transfer mechanism of the rubber injection molding machine further includes a pad 50, and the floating pallet 30 is placed on the pad 50. There are four floating pallets 30, and the four floating pallets 30 are arranged at intervals.

[0043] The four groups of floating pallets 30 are symmetrically distributed. Such a layout is conducive to balancing the weight distribution of the mold, ensuring the vertical stability of the mold during the lifting process, reducing deflection or vibration, thereby improving the molding accuracy and the overall stability of the equipment. In addition, when the mold position needs to be adjusted or maintenance is required, each floating pallet 30 can be fine-tuned independently to adapt to the different needs of the mold and ensure the parallelism and verticality of the mold when it is closed. The pad 50 is set as the basic support platform to better disperse the pressure from the clamping cylinder and evenly transmit it to the mold through the four floating pallets 30, reducing stress concentration, thereby improving product quality and production efficiency.

[0044] Please refer to Figures 1 to 3 In one embodiment of the utility model, the mold moving mechanism of the rubber injection machine also includes a driving component 60, and the driving component 60 drives the mold transporting slide 20 to move. The driving component 60 includes a motor, a driving gear and a rack. The motor and the driving gear are arranged on the pad 50, and the rack is arranged on the mold transporting slide 20.

[0045] In this embodiment, the motor drive ensures the smoothness and accuracy of the movement of the mold moving slide 20. Compared with manual or hydraulic drive, the motor drive can provide more accurate speed control and position control. The direct meshing transmission mode of the gear and the rack reduces the energy loss and power lag in the transmission process, ensures efficient energy conversion, and makes the entire mold moving process more responsive, especially in the case of frequent mold opening and closing, which can significantly shorten the cycle time. The motor and gear device are located on the pad 50, away from the direct mold operation area, reducing the possibility of contamination and wear, easy to regularly inspect and maintain, and improving the reliability and service life of the overall system.

[0046] Please refer to Figures 1 to 3 In one embodiment of the present invention, the driving gear and the rack are arranged in the interval space between the floating pallets 30.

[0047] Placing the driving gear and rack in a hidden position between the floating pallets 30 can effectively prevent external pollutants such as dust and oil from entering the meshing part of the gear and rack, reduce wear and extend the service life of the driving component. At the same time, it can also reduce the damage to the driving gear and rack caused by accidental collision. Placing the driving gear and rack inside can effectively isolate the noise generated when the motor and gear mesh. At the same time, the hidden driving mechanism makes the appearance of the machine neater, reduces the exposed moving parts, improves the safety of the operator, and reduces the risk of accidental injury.

[0048] Please refer to Figures 1 to 3In one embodiment of the utility model, the mold transfer mechanism of the rubber injection molding machine further includes a slide rail 70 , the mold transfer slide plate 20 moves along the slide rail 70 , and the slide rail 70 limits the movement of both sides of the floating support plate 30 .

[0049] The mold transporting slide plate 20 slides in the slide groove through the slide rail 70, which improves the sliding convenience of the mold transporting slide plate 20, and when the mold transporting slide plate 20 and the floating pallet 30 slide in the slide rail 70, the slide rail 70 can limit the mold transporting slide plate 20 and the floating pallet 30, ensuring the guiding accuracy of the mold transporting slide plate 20 and the floating pallet 30 during the sliding process. At the same time, the setting of the slide rails 70 on both sides provides a stable guide and support for the mold transporting slide plate 20 and the floating pallet 30, which can maintain good stability even when subjected to a large load or high-speed movement, reduce deflection and vibration, and extend the service life of the equipment. Furthermore, the design of setting the slide rail 70 on the mold transporting slide plate 20 and the floating pallet 30 makes the mold transporting slide plate 20 and the floating pallet 30 as independent modules, which are easy to install, disassemble and maintain.

[0050] Please refer to Figures 1 to 3 In one embodiment of the utility model, the slide rail 70 includes a first slide groove and a second slide groove, both sides of the mold transport slide plate 20 are accommodated in the first slide groove, and both sides of the floating pallet 30 are accommodated in the second slide groove.

[0051] The height of the first chute and the second chute respectively provides a larger activity space for the mold transporting slide plate 20 and the floating support plate 30, ensuring that the mold transporting slide plate 20 and the floating support plate 30 will not interfere with the top of the first chute and the second chute when moving up and down or forward and backward, thereby reducing the running resistance and making the movement smoother and more stable. Since there is enough clearance between the mold transporting slide plate 20 and the floating support plate 30 and the chute wall, the chance of direct contact is reduced, thereby reducing the wear caused by friction, extending the service life of the components, and reducing the maintenance cost. Even when the moving pad 12 is subjected to uneven load or tilt, the higher chute can provide sufficient support range to maintain the stability of the moving pad 12, avoid deviation or falling off, and enhance the stability and safety of the entire mold. In this embodiment, the chute has a first limiting wall and a second limiting wall opposite to each other in the up and down direction, and the side edge of the moving pad 12 is located between the first limiting wall and the second limiting wall, and the height between the first limiting wall and the second limiting wall is greater than the height of the mold transporting slide plate 20 and the floating support plate 30.

[0052] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
