[0022] Example two:

[0023] As Figures 1-5As shown, the base 1 of the utility model through optical axis 2 fixed installation top seat 3, on optical axis 2, between base 1 and top seat 3 swing joint has movable platform 4, top seat 3 fixed installation driving motor 5, driving motor 5 is driven to connect movable platform 4 through rack 6, movable platform 4 is fixedly installed upper die plate 8 through adjusting assembly 7, base 1 is equipped with sliding slot 9, and sliding slot 9 is swingly installed lower die plate 11 through slide rail 10, lower die plate 11 is fixedly installed pull handle 12, and sliding slot 9 is fixedly installed first limiting block 13, in the use process, the operator first places silica gel material on lower die plate 11, then, driving motor 5 starts, and movable platform 4 is driven to move down through rack 6, movable platform 4 drives upper die plate 8 to descend until with lower die plate 11 contact, upper die plate 8 and lower die plate 11 jointly exert pressure on silica gel material, and it is shaped as the required watchband shape, after pressing, driving motor 5 reverses operation, and movable platform 4 is driven to move up, so that upper die plate 8 and lower die plate 11 are separated, at this time, the operator can pull lower die plate 11 out from sliding slot 9 through pull handle 12, since lower die plate 11 can be completely pulled out, the operator can take out the shaped silica gel watchband without needing to stretch hand between the mould, and the operation safety is greatly improved, after taking out finished product, the operator pushes lower die plate 11 back to sliding slot 9, first limiting block 13 ensures that lower die plate 11 is pushed back to the correct position, and is ready for the next pressing, in the whole process, the up-and-down movement of movable platform 4 is accurately controlled by driving motor 5, ensures that the strength of each pressing is consistent, and improves the stability of product quality, the existence of adjusting assembly 7 makes that the position of upper die plate 8 can be fine-tuned, when replacing different size mould, through adjusting assembly 7 fine-tuning upper die plate 8, makes upper die plate 8 and lower die plate 11 align, increases the application range and flexibility of the press machine, the design of sliding slot 9 and slide rail 10 not only facilitates the pull of lower die plate 11, but also ensures the stability of lower die plate 11 in the use process, slide rail 10 ensures that lower die plate 11 moves smoothly in the horizontal direction, and simultaneously prevents lower die plate 11 from deviating or deforming in the pressing process, the design of pull handle 12 considers the ergonomics principle, so that the operator can easily pull out and push in lower die plate 11, first limiting block 13 not only ensures the correct positioning of lower die plate 11, but also prevents lower die plate 11 from being excessively pushed into sliding slot 9, this design not only ensures the accurate alignment of upper and lower die plates 11 in the pressing process, but also avoids the equipment damage caused by operation failure, in general, this silica gel watchband press machine is improved significantly in operation safety, convenience and accuracy through multiple innovative designs.

[0024] Example three:

[0025] As Figures 1-5As shown, this utility model further optimizes the alignment mechanism of the upper template 8 and the lower template 11. Specifically, guide sleeves 14 are fixedly installed at all four corners of the upper template 8, and guide rods 15 are fixedly installed at all four corners of the lower template 11. During the pressing process, when the movable table 4 lowers the upper template 8, the guide sleeves 14 at the four corners of the upper template 8 gradually fit onto the guide rods 15 at the four corners of the lower template 11. This design ensures that the upper and lower templates 11 maintain precise alignment during the pressing process. The cooperation between the guide sleeves 14 and the guide rods 15 plays a dual role. First, they guide the upper template 8 to move to the correct position before pressing begins. Even if the upper template 8 deviates slightly during descent, the guide rods 15 will guide the guide sleeves 14 to return the upper template 8 to the correct position. This greatly reduces the scrap rate caused by template misalignment. During the pressing process, the tight cooperation between the guide sleeves 14 and the guide rods 15 prevents relative displacement between the upper and lower templates 11. This is especially important for silicone watch straps, which require high precision, as even a small misalignment can lead to defective products. Because the upper and lower mold plates 11 can be quickly and accurately aligned, operators do not need to spend extra time adjusting the mold plate positions, thus speeding up each production cycle. By installing guide sleeves 14 at the four corners of the upper mold plate 8 and guide posts 15 at the four corners of the lower mold plate 11, this silicone watch strap molding machine significantly improves the precision and consistency of the pressing process, providing a strong guarantee for the production of high-quality silicone watch straps.

[0026] Example 4:

[0027] like Figures 1-5 As shown, this utility model further improves the limiting mechanism of the lower template 11. Specifically, the lower template 11 is provided with a stop 16, and a second limiting block 17 is fixedly installed on the base 1. The stop 16 is located on one side of the lower template 11. When the operator pulls the pull handle 12, the lower template 11 moves along the slide rail 10 in the slide groove 9. When the lower template 11 is pulled out to the predetermined position, the stop 16 will contact the second limiting block 17 on the base 1, preventing the lower template 11 from moving further. The main purpose of this design is to prevent the operator from pulling the lower template 11 out excessively. Without this restriction, the operator may inadvertently pull the lower template 11 completely out of the slide groove 9, causing the slide rail 10 to disengage from the slide groove 9. This will not only interrupt the workflow but may also cause equipment damage or personal injury.

[0028] Example 5:

[0029] like Figures 1-5As shown, the adjusting assembly 7 of the utility model is composed of a matching block 18, a pressing block 19 and a locking bolt 20. The matching block 18 is fixedly connected with the movable table 4, and provides a stable base for the whole adjusting assembly 7. The pressing block 19 is designed with a protruding block 21 structure, which is matched with a groove 22 on the upper die plate 8. In use, the protruding block 21 of the pressing block 19 is embedded into the groove 22 of the upper die plate 8, and the pressing block 19 is firmly screwed with the matching block 18 through the locking bolt 20. This design forms an adjustable connecting mechanism between the upper die plate 8 and the movable table 4. The operator can adjust the position of the pressing block 19 according to different sizes of the mold. When adjusting, first loosen the locking bolt 20, then move the pressing block 19 to the appropriate position, make the protruding block 21 accurately align with the groove 22, and finally tighten the locking bolt 20 to fix the pressing block 19. At the same time, the matching design of the protruding block 21 and the groove 22 increases the contact area between the upper die plate 8 and the pressing block 19, improves the stability of the connection, and reduces the displacement or shaking that may occur during pressing. The matching block 18 as the fixed connection point with the movable table 4 ensures the stability and accuracy of the whole adjusting assembly 7. The use of the locking bolt 20 not only facilitates the adjustment, but also ensures the firmness after adjustment.

[0030] Example six:

[0031] As Figures 1-5 shown, the optical axis 2 is fixedly installed with a stop switch 23. The optical axis 2 is an important structural component of the compression molding machine, connecting the base 1 and the top seat 3, and providing vertical movement guidance for the movable table 4. The stop switch 23 is installed at an appropriate position of the optical axis 2, and is used to control the upward stroke of the movable table 4. When the compression molding machine is working, the driving motor 5 drives the movable table 4 to move up and down along the optical axis 2. After the pressing is completed, the movable table 4 needs to rise to separate the upper and lower die plates 11. At this time, the stop switch 23 plays a crucial role. When the movable table 4 rises to the predetermined position, it will trigger the stop switch 23 installed on the optical axis 2. After the stop switch 23 is triggered, it immediately sends a signal to the control system, and the control system stops the operation of the driving motor 5, thereby stopping the upward movement of the movable table 4. This design effectively prevents the movable table 4 from continuing to rise and hitting the top seat 3.
