[0027] The utility model provides a mold shifting mechanism for a rubber injection machine.

[0028] A heating plate, on which the mold is mounted, and which heats up to maintain the temperature of the mold;

[0029] A slide plate 10, wherein the heating plate is arranged on the slide plate 10;

[0030] A base 20 supports the slide 10. The base 20 is provided with a guide rail 21. The slide 10 slides on the base 20 along the guide rail 21.

[0031] The driving assembly 30 includes a driving member 31 and a transmission member 32 . The driving member 31 is disposed on the base 20 , and the transmission member 32 is disposed on the slide 10 . The driving member 31 drives the slide 10 to slide via the transmission member 32 .

[0032] The utility model application discloses a mold shifting mechanism for a rubber injection machine. During use, a slide plate 10 can be used to carry and move the mold. By clearly separating the base 20, the slide plate 10 and the drive assembly 30, structural modularization is achieved, which is conducive to production assembly, maintenance and replacement of parts. If a part is damaged or needs to be upgraded, it can be handled separately more easily, reducing the impact on the entire system. The slide plate 10 can be slidably arranged on the base 20, so that the installation position of the mold can be adjusted more flexibly, and can adapt to molds of different sizes and shapes, thereby improving the versatility of the rubber injection machine. The drive connection design of the drive assembly 30, the slide plate 10 and the base 20 not only facilitates daily cleaning operations, but also, compared with the prior art in which the drive assembly 30 is installed on the left or right side of the mold, this design can maximize the use of vertical space and make the machine more compact as a whole. In a limited factory space, such a design helps to improve space utilization, which is very beneficial for workshop layout and production line planning. Placing the drive assembly 30 below the mold bearing surface can, to a certain extent, prevent the rubber material, coolant or other debris splashed during the production process from directly contacting the drive assembly 30, reduce the risk of pollution and damage, and extend the service life of the drive assembly 30. The lower position of the drive assembly 30 can lower the center of gravity of the machine, increase the overall stability of the equipment, and effectively reduce vibration, improve processing accuracy and product quality, especially during high-speed or high-pressure injection molding operations. And because the drive assembly 30 does not directly contact or interfere with the mold, the installation, disassembly and maintenance process of the mold is simpler and faster. The staff can more conveniently approach the mold for operation without having to consider the layout of the drive system too much. In the present application scheme, the heating plate is in direct contact with the mold, and the mold can be heated or insulated more directly and quickly to ensure that the temperature inside the mold is uniform, which is crucial for the molding of rubber products. Accurate temperature control helps to improve the fluidity and curing process of rubber and improve the quality of products. Among them, preheating the mold by the heating plate can effectively shorten the time for the mold to reach the working temperature, accelerate the production cycle, and improve production efficiency. This is particularly important for large-scale production and can significantly increase production capacity. Furthermore, compared with the traditional overall heating method, the local heating heating plate design can more effectively concentrate energy on the key areas that need to be heated, reduce energy waste, and achieve energy conservation and emission reduction. In addition, the uniform temperature distribution of the heating plate can avoid cold spots and hot spots in the rubber during the molding process, reduce product defects caused by uneven temperature, such as uneven shrinkage and internal stress concentration, thereby improving the dimensional stability and appearance quality of the product. As an independent component, the heating plate can be easily maintained or replaced once it fails or needs to be replaced, without causing a major impact on the entire mold or machine, reducing maintenance costs and downtime.

[0033] Please refer to Figure 1 to Figure 2The heating plate is arranged on the top surface of the slide plate 10 , the transmission member 32 is arranged on the bottom surface of the slide plate 10 , and the guide rail 21 supports the bottom surface of the slide plate 10 .

[0034] Furthermore, placing the transmission member 32 below the mold bearing surface can, to a certain extent, prevent the rubber material, coolant or other debris splashed during the production process from directly contacting the transmission member 32, reduce the risk of pollution and damage, and extend the service life of the transmission member 32. The lower position of the transmission member 32 can lower the center of gravity of the machine and increase the overall stability of the equipment, especially in high-speed or high-pressure injection molding operations, which can effectively reduce vibration and improve processing accuracy and product quality. And because the transmission member 32 does not directly contact or interfere with the mold, the installation, disassembly and maintenance of the mold are simpler and faster. The staff can more conveniently approach the mold for operation without having to consider the layout of the drive system too much. Furthermore, since a large amount of heat is generated during the rubber injection process, the transmission member 32 is located below to a certain extent to avoid direct exposure to high temperature environment, which is helpful for heat dissipation and thermal management, and protects sensitive electronic and mechanical components from thermal damage. The transmission member 32 is hidden under the mold, which can reduce the risk of accidental contact by the operator and improve the safety of the workplace. It is understandable that the transmission member 32 can be chain driven, synchronous belt driven, or gear driven. The driving member 31 can be an electric motor, a hydraulic cylinder, or a pneumatic cylinder.

[0035] Please refer to Figure 1 to Figure 2 The transmission member 32 is a rack, and the transmission member 32 is meshed with the output gear of the driving member 31 to drive the slide plate 10 to move.

[0036] In this embodiment, the direct meshing transmission mode between the driving member 31 and the rack reduces the energy loss and power lag in the transmission process, ensures efficient energy conversion, and makes the entire mold shifting process more responsive, especially when frequent mold opening and closing are required, the cycle time can be significantly shortened. The rack is extended along the movement direction of the slide 10, which can provide a higher positioning accuracy in the movement direction of the slide 10, ensuring that the repeated positioning error of the slide 10 during the reciprocating movement is small. If the moving distance needs to be adjusted or maintenance is required, it can be achieved by adjusting the position of the rack or replacing the worn gear. This structure is convenient for maintenance and adjustment. It can be understood that the driving member 31 can usually use an electric motor (such as a servo motor or a stepper motor) because it can provide precise control and sufficient torque, which is suitable for occasions requiring precise control. In addition, hydraulic motors or pneumatic cylinders are also feasible options, especially when greater thrust or specific working environments (such as fire and explosion requirements) are required. Considering the cooperation with the rack, the driving member 31 is generally designed in the form of a gear, which can be a spur gear, a helical gear or a worm gear, etc., depending on factors such as the required transmission ratio, space restrictions and noise control. For example, spur gears are suitable for simple and direct transmission, while helical gears or spiral gears can provide smoother and quieter operation and are suitable for application scenarios with higher requirements for noise control.

[0037] Please refer to Figure 1 to Figure 2 , the transmission member 32 is located between the two sides of the skateboard 10.

[0038] Placing the transmission member 32 in a hidden position between the two sides of the slide plate 10 can effectively prevent external pollutants such as dust and oil from entering the meshing part of the rack, reduce wear, and extend the service life of the drive assembly 30. At the same time, it can also reduce the damage to the transmission member 32 caused by accidental collision. The transmission member 32 is built-in to effectively isolate the noise generated when the transmission member 32 and the drive member 31 are meshed. At the same time, the hidden drive 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.

[0039] Please refer to Figure 1 to Figure 2 The transmission member 32 is a belt, and the transmission member 32 and the driving wheel of the driving member 31 are frictionally transmitted to drive the skateboard 10 to move.

[0040] Compared with other transmission methods such as gears, the component cost of belt drives is usually lower. The belt transmits power by contacting the drive wheel of the driving member 31 and due to the friction between the two. When the driving member 31 rotates, the drive wheel on it will drive the belt to rotate together. The belt then transmits this rotational motion to other components connected to it. Compared with other transmission methods such as gears, the component cost of belt drives is usually lower. Belt drives are smoother and quieter than gear drives. The elasticity of the belt can absorb the impact and vibration during machine operation to a certain extent and protect other components. The belt drive system is relatively simple, and it is relatively easy to install, adjust and replace the belt.

[0041] Please refer to Figure 1 to Figure 2 The guide rail 21 includes a slide groove, and the slide groove is located on both sides of the slide plate 10. The two sides of the slide plate 10 slide along the slide groove respectively.

[0042] It is understandable that the height of the slide grooves provided on the guide rails 21 provide a larger space for the slide plate 10 to move, ensuring that the slide plate 10 will not interfere with the top and / or bottom of the slide grooves of the two slide rails 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 gap between the slide plate 10 and the slide groove wall, the chance of direct contact is reduced, thereby reducing the wear caused by friction, extending the service life of the components, and reducing maintenance costs. Even when the slide plate 10 is subjected to uneven loads or tilts, the higher slide groove can provide sufficient support range to keep the slide plate 10 stable, avoid deviation or falling off, and enhance the stability and safety of the entire mold. In this embodiment, the number of guide rails 21 is 2, which are respectively installed on both sides of the slide plate 10.

[0043] Please refer to Figure 1 to Figure 2 The slide groove has a first limiting wall and a second limiting wall opposite to each other in the up-down direction, and the side edge of the slide plate 10 is located between the first limiting wall and the second limiting wall.

[0044] The combined effect of the first limiting wall and the second limiting wall provides the slide plate 10 with a precise up and down motion trajectory, ensuring that the slide plate 10 maintains a straight line motion during the motion process, preventing deflection, and improving the stability and accuracy of the mold closing and opening process. At the same time, through the guiding effect of the first limiting wall and the second limiting wall, unnecessary friction and collision between the slide plate 10 and the slide groove are reduced, which helps to extend the service life of the slide plate 10 and the slide groove and reduce maintenance costs. If there is a need for fine-tuning of the movement of the slide plate 10 or adjustment after long-term use, the design of the first limiting wall and the second limiting wall facilitates fine-tuning of the position or replacement of worn parts, which is conducive to maintaining the optimal working state of the equipment.

[0045] Please refer to Figure 1 to Figure 2The rubber injection molding machine mold transfer mechanism also includes a roller 40, which is rotatably mounted on the side wall of the guide rail 21 and close to the bottom of the slide groove. The upper surface of the roller 40 is at least partially higher than the bottom of the slide groove.

[0046] By replacing the direct sliding contact with the guide rail 21 with the rolling contact between the bottom of the slide 10 and the roller 40, the friction resistance is greatly reduced, making the movement of the slide 10 easier and smoother, reducing power consumption and improving work efficiency. The direct wear between the slide 10 and the guide rail 21 is reduced, and the roller can be replaced independently as a consumable part, which not only protects the guide rail 21 and the main structure of the slide 10, but also reduces the maintenance cost and prolongs the service life of the entire mold shifting mechanism. In addition, the noise generated by rolling friction is much smaller than that generated by sliding friction. The use of the roller 40 helps to create a quieter working environment, which meets the requirements of modern factories for noise control. Furthermore, the arrangement of the rollers (the first roller is close to the bottom of the first chute, and the upper surface of the second roller is at least partially higher than the bottom of the chute) helps to improve the lateral stability of the slide 10 during movement, and can remain stable even when moving quickly or under a large injection pressure, reducing vibration. In this embodiment, the rollers 40 are respectively installed on both sides of the slide 10.

[0047] Please refer to Figure 1 to Figure 2 , the driving member 31 is a hydraulic motor or an electric motor.

[0048] Preferably, in this embodiment, by providing two options of hydraulic motor and electric motor, the most suitable power solution can be flexibly selected according to the needs of the actual application scenario. Hydraulic motors are suitable for occasions that require large torque output, fast response speed and strong environmental adaptability, such as in heavy machinery or specific industrial environments. Electric motors are more suitable for applications with stable power supply, high efficiency and low maintenance costs, such as automated production lines, precision machining and other fields.
