Description

Technical Field

[0001] This utility model relates to the technical field of rubber injection molding equipment, specifically a mold transfer mechanism for a rubber injection machine. Background Technology

[0002] In existing technologies, the mold-moving structure of rubber injection molding machines uses hydraulic cylinders as the actuators. The cylinder body is long and occupies external space. In addition, the hydraulic cylinder has high sealing requirements, and leakage will occur once the seal fails. The liquid inside the cylinder is easily affected by external contaminants and needs to be cleaned and replaced regularly. Since the hydraulic system involves the cooperation of multiple components such as hydraulic cylinders, hydraulic pumps, and hydraulic valves, it is difficult to troubleshoot when the system fails, and professional maintenance technology and related knowledge are required.

[0003] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0004] This utility model addresses the above-mentioned technical problems by providing a mold-shifting mechanism for a rubber injection molding machine. It features a compact structure, small equipment space occupation, long service life, and good maintainability. The stroke can be changed by adding or removing chain links. It overcomes the shortcomings of traditional hydraulic cylinders, such as large equipment space occupation and difficulty in use and maintenance.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A mold-moving mechanism for a rubber injection molding machine includes a loading plate, a linear actuator, a mold lifter, and a mold-moving slide rail;

[0007] A mold is set on the loading template;

[0008] The linear actuator is equipped with a drive motor, a double chain and a chain storage box, and the ends of the double chain are connected to the mounting template;

[0009] The lifting device is located below the mounting plate to provide floating support;

[0010] The mold moving slide rail extends along both sides of the mounting template;

[0011] When the linear actuator is working, the drive motor rotates and drives the double chains to mesh into a single column, pushing the mounting template out along the mold transfer rail; when retracting, the drive motor rotates in the opposite direction, causing the double chains to separate and be stored in the chain storage box, and pulling the mounting template back.

[0012] The mold-moving mechanism of this rubber injection molding machine uses a linear actuator instead of the traditional hydraulic drive mechanism, overcoming the shortcomings of hydraulic cylinders, such as large space occupation and difficulty in use and maintenance. The drive motor used in the linear actuator is small in size, and the double chains can be stored separately in the chain storage box when the mold plate is retracted, which also saves the size of the equipment.

[0013] This mold-moving mechanism is very convenient to use and maintain. The structure of the double-chain drive motor allows for maintenance-free operation. The double-chain meshing is a rigid single-column design, providing high thrust, good stability, and smooth mold-mounting movement. The mechanism has a compact structure, occupies little equipment space, has a long service life, and is easy to maintain. The mold-mounting stroke can be adjusted by adding or removing links from the double chains.

[0014] The mold lifting device of the mold moving mechanism provides floating support for the mold plate, and together with the mold moving slide rails on both sides, it ensures smooth and stable back-and-forth movement of the mold plate, avoiding any jamming.

[0015] A further optimized solution includes a hot plate located below the mounting plate for mold heating. The mold is directly heated to the required temperature on the mold transfer mechanism, eliminating the need for separate mold heating on the rubber injection molding machine, thus saving mold heating time and improving work efficiency.

[0016] A further optimized design includes several bearing rollers located at the bottom of the mounting template and on both sides of the hot plate, enabling low-friction guided movement between the mounting template and the mold-moving slide rail. The bearing rollers significantly reduce friction during the mold-moving process and also provide guidance, ensuring the stable and reliable movement of the mold.

[0017] A further optimization of the design includes a heat insulation plate positioned directly below the hot plate. The heat insulation plate helps prevent heat loss from the hot plate and protects other components or the environment from the high temperature of the hot plate.

[0018] The design was further optimized by adjusting the stroke length of the mounting platen by adding or removing links from the double chain. This adjustment of the mounting platen stroke can accommodate the needs of different rubber injection molding machines or molds.

[0019] The mold-shifting mechanism of the rubber injection molding machine of this invention has the following technical advantages compared with the prior art:

[0020] 1. The compact structure occupies little equipment space. The small size of the drive motor itself and the chain storage box provide dual protection for the small size of the mold moving mechanism.

[0021] 2. The contradiction between space and thrust in mold movement is resolved by switching between the engagement and disengagement states of the double chain;

[0022] 3. The addition or removal of chain links of the double chain enables adjustment of the template loading stroke, breaking through the fixed stroke limitation of the hydraulic cylinder. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0027] like Figures 1 to 2 As shown, this invention relates to a specific embodiment of the mold-shifting mechanism of a rubber injection molding machine.

[0028] like Figure 1 As shown, the mold-moving mechanism of the rubber injection machine in this embodiment includes a loading plate 2, a linear actuator 3, a mold lifter 4, and a mold-moving slide rail 5;

[0029] Set the mold on template 2;

[0030] like Figure 2 As shown, the linear actuator 3 is equipped with a drive motor 8, a reducer 9, a double chain 10, and a chain storage box 11. The end of the double chain 10 is connected to the mounting plate 2. The drive motor 8 is connected to the reducer 9. The reducer 9 drives the two sprockets to rotate, which drives the double chain 10 to move back and forth in a linear motion. The two sprockets are located in the middle of the chain storage box 11.

[0031] The lifting device 4 is located below the mounting template 2 to provide floating support;

[0032] The formwork sliding rail 5 extends along both sides of the mounting template 2;

[0033] When the linear actuator 3 is working, the drive motor 8 rotates and drives the double chain 10 to mesh into a single column to push the template 2 out along the mold transfer rail 5; when retracting, the drive motor 8 rotates in the opposite direction and drives the double chain 10 to separate and be stored in the chain storage box 11 and pulls the template 2 back.

[0034] The mold-moving mechanism of this rubber injection molding machine adopts a linear actuator 3 instead of the traditional hydraulic drive mechanism, overcoming the shortcomings of hydraulic cylinders, such as large space occupation and difficulty in use and maintenance. The drive motor 8 used in the linear actuator 3 is small in size, and the double chains 10 can be separately stored in the chain storage box 11 when the mold plate 2 is retracted, which also saves the size of the equipment.

[0035] The mold-shifting mechanism is very convenient to use and maintain. The structure of the drive motor 8 transmitting the double chain 10 is completely maintenance-free. The double chain 10 meshes as a rigid single column, providing high thrust and good stability, ensuring smooth movement of the mold plate 2. The mold-shifting mechanism has a compact structure, occupies little equipment space, has a long service life, and is easy to maintain. The stroke of the mold plate 2 can be adjusted by adding or removing links of the double chain 10.

[0036] The mold lifting device 4 of the mold moving mechanism provides floating support for the mold plate 2, and together with the mold moving slide rails 5 on both sides, it ensures smooth and stable back-and-forth movement of the mold plate 2, avoiding any jamming.

[0037] like Figure 1 As shown, the mold-moving mechanism of the rubber injection molding machine also includes a hot plate 1, which is located below the mounting plate 2 and is used for mold heating. The mold is directly heated to the required temperature on the mold-moving mechanism, eliminating the need for separate mold heating on the rubber injection molding machine, thus saving mold heating time and improving work efficiency.

[0038] like Figure 1 As shown, the mold-moving mechanism of the rubber injection molding machine also includes several bearing rollers 6, which are located at the bottom of the mounting platen 2 and on both sides of the hot plate 1, enabling low-friction guided movement between the mounting platen 2 and the mold-moving slide rail 5. The bearing rollers 6 significantly reduce the friction of the mounting platen 2 during mold-moving and also provide guidance, ensuring the stable and reliable movement of the mold by the mounting platen 2.

[0039] like Figure 1 As shown, the mold transfer mechanism of the rubber injection molding machine also includes a heat insulation plate 7, which is located directly below the hot plate 1. The heat insulation plate 7 helps to prevent heat loss from the hot plate 1 and to prevent the high temperature of the hot plate 1 from affecting other parts or the environment.

[0040] like Figure 2 As shown, the stroke length of the mounting plate 2 can be adjusted by adding or removing links of the double chain 10. This adjustment of the mounting plate 2's stroke can accommodate the needs of different rubber injection molding machines or different molds.

[0041] The mold-shifting mechanism of this rubber injection molding machine has a compact structure, occupies little equipment space, has a long service life, and is easy to maintain. The stroke can be changed by adding or removing chain links. It overcomes the shortcomings of traditional hydraulic cylinders, which occupy a large amount of equipment space and are difficult to use and maintain.

[0042] In summary, as described in the specification and figures, this utility model has been manufactured into actual samples and subjected to multiple use tests. The test results demonstrate that this utility model achieves its intended purpose, and its practicality is beyond doubt.
