[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0040] Example 1

[0041] This utility model provides, for example Figure 1-3 The silicone pressing device shown includes a worktable 1, a cylinder 3, a transmission frame 4, an upper mold 5, a lower mold 6, a mounting mechanism 7, and a guide and limiting mechanism 8. A fixed frame 2 is fixedly connected to the top of the worktable 1. The cylinder 3 is fixedly installed on the outer wall of the fixed frame 2, and its output end is connected to the transmission frame 4. The upper mold 5 and the lower mold 6 cooperate to press silicone parts. The lower mold 6 also has an alignment rod for aligning with the upper mold 5, thus ensuring the accuracy and stability of the pressing process. The mounting mechanism 7 is respectively located on one side of the worktable 1 opposite to the transmission frame 4, and is used to install the upper mold... The upper mold 5 and lower mold 6 are mounted on the fixed frame 2, and the guide limiting mechanism 8 is used to guide the displacement of the transmission frame 4 and limit the displacement of the installation mechanism 7. The upper mold 5 and lower mold 6 on the transmission frame 4 are driven by the cylinder 3 to cooperate with each other. This can replace manual labor for batch pressing of silicone parts, reduce the labor intensity of workers, and reduce labor costs. When switching between different silicone parts production needs, the upper mold 5 and lower mold 6 can be replaced simply by the installation mechanism 7 and the guide limiting mechanism 8. The whole process is efficient and fast, which can significantly shorten the mold change time, improve the utilization efficiency of the equipment, and speed up the production progress.

[0042] Specifically, the installation mechanism 7 includes a connecting rod 71, a mounting plate 72, a first compression spring 73, and a snap-fit ​​assembly 74. The connecting rod 71 is slidably inserted into the transmission frame 4. The mounting plate 72 is fixedly connected to the bottom end of the connecting rod 71 and the top end of the worktable 1, respectively. An installation groove is provided on the opposite side of the mounting plate 72. Mounting rods 9 are fixedly connected to the outer walls of the upper mold 5 and the lower mold 6. The mounting rods 9 are slidably inserted into the inner cavity of the mounting groove. The first compression spring 73 is sleeved on the outside of the connecting rod 71. One end of the first compression spring 73 is fixedly connected to the mounting plate 72, and the other end of the first compression spring 73 is fixedly connected to the transmission frame 4. The first compression spring 73 provides a stable elastic force to one of the mounting plates 72, so that when the cylinder 3 drives the transmission frame 4 to move, it can first position the silicone part and then squeeze it for installation. The snap-fit ​​assembly 74 is set inside the mounting plate 72 and is used for multi-point positioning of the mounting rods 9.

[0043] Furthermore, the snap-fit ​​assembly 74 includes a pressing plate 741, a snap-fit ​​rod 742, and a second compression spring 743. The mounting plate 72 has symmetrically formed pressing grooves inside, with the pressing plate 741 located inside the pressing grooves. The snap-fit ​​rod 742 is fixedly inserted and connected to the pressing plate 741. A snap-fit ​​hole is formed on the outer wall of the mounting rod 9. One end of the snap-fit ​​rod 742 passes through a limiting frame and is slidably inserted and connected to the inner cavity of the snap-fit ​​hole. The second compression spring 743 is sleeved on the outside of the snap-fit ​​rod 742. One end of the second compression spring 743 is fixedly connected to the pressing plate 741, and the other end is fixedly connected to the inner wall of the pressing groove. The second compression spring 743 provides a stable elastic force to the snap-fit ​​rod 742 through the pressing plate 741, enabling the snap-fit ​​rod 742 to be stably snapped into the snap-fit ​​hole. This allows the upper mold 5 and the lower mold 6 to be installed on the mounting plate 72. Replacement is also possible by simply pulling the snap-fit ​​rod 742 to disengage it from the positioning hole.

[0044] Example 2

[0045] Based on Example 1, such as Figure 4 As shown, the guide limiting mechanism 8 includes a horizontal plate 81, a guide rod 82, and a positioning component 83. The top of the fixed frame 2 has a groove, and the horizontal plate 81 is slidably inserted into the inner cavity of the groove. The guide rod 82 is symmetrically fixedly connected to the bottom end of the horizontal plate 81. The transmission frame 4 is slidably inserted into the guide rod 82. The top of the worktable 1 has a connecting hole, and the guide rod 82 passes through the groove and is slidably inserted into the inner cavity of the connecting hole to limit the displacement of the locking rod 742. The positioning component 83 is set inside the horizontal plate 81. The horizontal plate 81 can be fixedly installed on the inner wall of the groove through the positioning component 83. At this time, the guide rod 82 is in a vertical state, which can not only guide the transmission frame 4, but also limit the locking rod 742 to prevent it from sliding outward, so that the installation of the upper mold 5 and the lower mold 6 fails, thus ensuring the stability during use.

[0046] Furthermore, the positioning assembly 83 includes a positioning rod 831, a pull rod 832, and a third compression spring 833. Positioning grooves are formed on both sides of the horizontal plate 81, and positioning holes are formed on both sides of the inner wall of the grooves. One end of the positioning rod 831 is slidably inserted into the inner cavity of the positioning groove, and the other end of the positioning rod 831 is slidably inserted into the inner cavity of the positioning hole. A pull groove communicating with the positioning groove is formed at the top of the horizontal plate 81. The pull rod 832 passes through the pull groove and is fixedly connected to the positioning rod 831. The third compression spring 833 is disposed inside the positioning groove, and one end of the third compression spring 833 is fixedly connected to the positioning rod 831. The other end of the spring 833 is fixedly connected to the inner wall of the positioning groove. The third compression spring 833 provides a stable elastic force to the positioning rod 831, so that the positioning rod 831 can be stably engaged with the positioning hole, and the horizontal plate 81 can be stably installed inside the groove. When it is necessary to replace the upper mold 5 and the lower mold 6, simply pull the positioning rod 831 with the pull rod 832 to disengage the positioning rod 831 from the positioning hole, and the guide rod 82 can be pulled out of the fixing frame 2. At this time, the guide rod 82 no longer limits the locking rod 742, and the locking rod 742 can be pulled to replace the upper mold 5 and the lower mold 6, which is convenient for use.

[0047] 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.
