The silicone processing mold includes a first mold 1 and a second mold 2 that can be matched. The first mold 1 has a first working area 11, and the second mold 2 has a second working area 21 and a third working area 22. The second mold 2 has a material pressing mechanism 23 that is connected to the second working area 21. The first working area 11 can be connected to the second working area 21 to form a first processing cavity 3 for processing the first silicone product. The first working area 11 can be connected to the third working area 22 and cooperate with the first silicone product to form a second processing cavity 4 for processing the second silicone product. During processing, the first working area 11 is first connected to the second working area 21 to process the first silicone product, and then the second mold 2 or the first mold 1 is moved to connect the first working area 11 with the third working area 22 to process the second silicone product.

[0028] In the illustrated embodiment, the first mold 1 is located at the bottom and can be fixed to an external machine platform. The second mold 2 is located above the first mold 1. The second mold 2 is a movable mold that moves toward or away from the first mold 1 to achieve the connection or separation of the first mold 1 and the second mold 2. In other embodiments, the first mold 1 can be a movable mold and the second mold 2 can be a fixed mold. These are all similar extensions based on this embodiment, as long as the first mold 1 and the second mold 2 can be connected.

[0029] The first mold 1 includes a fixed platform 12 and a lower mold plate 13. The fixed platform 12 is used to secure to an external machine platform. The lower mold plate 13 is rotatably mounted above the fixed platform 12 and can rotate horizontally around its connection point with the fixed platform 12. A fixing assembly 14 is provided between the lower mold plate 13 and the fixed platform 12 to fix the rotational angle between the lower mold plate 13 and the fixed platform 12.

[0030] The first working area 11 is provided on the side of the lower template 13 facing the second mold 2 (i.e., the upper end surface of the lower template 13 in this embodiment). The first working area 11 includes a sinking table 111, and a plurality of first bosses 112 are provided at the bottom of the sinking table 111. The plurality of first bosses 112 are evenly spaced and arranged in a matrix on the sinking table 111. Figure 3 Each of the first bosses 112 is provided with a second groove 113, and the second groove 113 is formed by the upper end surface of the first boss 112 being recessed downward, and the shape of the second groove 113 matches the first silicone product to be processed. A pin 114 is passed through the second groove 113, and the end of the pin 114 matches the shape of the first silicone product. A template 5 is detachably provided in the first working area 11, and the shape of the template 5 matches the sinking table 111 so that it can be snapped into the sinking table 111. A perforation is provided on the lower end surface of the template 5 corresponding to the position of each of the first bosses 112 for the first boss 112 to pass through the perforation to the upper end surface of the template 5. A second boss 51 is convexly provided on the upper end surface of the template 5 corresponding to the position of each of the perforations, and the shape of the second boss 51 matches the second silicone product.

[0031] When the template 5 is located in the first working area 11, the first working area 11 can cooperate with the template 5 and the second mold 2 to press the second silicone product. When we process the first silicone product, the template 5 is not needed. In order to facilitate the storage of the template 5, the lower template 13 is also provided with a receiving groove for placing the template 5. When the first working area 11 is used to process the first silicone product, the template 5 can be placed in the receiving groove, which neither affects the processing operation in the first working area 11 nor causes the template 5 to be lost. In particular, in the embodiment shown, the receiving groove is another first working area 11, that is, the first working area 11 and the receiving groove are actually two first working areas 11 arranged side by side. When one of the first working areas 11 is processing the first silicone product, the template 5 is located in the other first working area 11 to cooperate with the processing of the second silicone product, which can improve the processing efficiency of the device. The first working area 11 and the storage groove (that is, the two first working areas 11 in this embodiment) are both provided with positioning bolts 115, and the template 5 is provided with positioning holes 52 that can be positioned and cooperated with the positioning bolts 115. When the template 5 is placed in the corresponding first working area 11, the positioning bolts 115 and the positioning holes 52 cooperate with each other to make the placement of the template 5 more accurate and more stable.

[0032] The fixing assembly 14 includes a first positioning slot 141 defined on the fixing platform 12, a second positioning slot 142 defined on the lower template 13, and a plug 143. Two second positioning slots 142 are symmetrically located on either side of the lower template 13. As the lower template 13 rotates, the two second positioning slots 142 can communicate with the first positioning slot 141. The plug 143 is inserted into the interconnected first and second positioning slots 141, 142 to secure the fixing platform 12 to the lower template 13. To facilitate rotation of the lower template 13, a first extension plate 131 is also provided on the lower template 13.

[0033] Please refer to Figure 5 、 Figure 6 and Figure 7The second mold 2 includes an upper mold plate 24 and an upper mold cover plate 25.

The second working area 21 and the third working area 22 are both opened on the lower end surface of the upper mold plate 24, and the second working area 21 and the third working area 22 are respectively arranged corresponding to the positions of the two first working areas 11. The lower end surface of the second working area 21 is recessed with a plurality of first grooves 211 upward (i.e., in the direction away from the first working area 11). The plurality of first grooves 211 are opened in a one-to-one correspondence with the plurality of bosses. Each group of corresponding first grooves 211, second grooves 113 and ejector pins 114 can cooperate with each other to enclose a first processing cavity 3 for processing the first silicone product. The third working area 22 is recessed upward (i.e., away from the first working area 11) with a third groove 221 that matches the second silicone product. There are multiple third grooves 221, each corresponding to a plurality of first grooves 211. Each corresponding set of first grooves 211, ejector pins 114, third grooves 221, second bosses 51, and the processed first silicone product together form the second processing chamber 4 that matches the second silicone product.

[0034] The pressing mechanism 23 is arranged at a position in the upper template 24 corresponding to the second working area 21. The pressing mechanism 23 includes a pressing plate 231. The upper template 24 is provided with a pressing cavity, and the pressing cavity is formed by the upper end surface of the upper template 24 being recessed downward. The pressing plate 231 is sealed and slides in the pressing cavity, and the pressing plate 231 slides in the pressing cavity along the vertical direction. The lower end of the pressing cavity is connected to the second working area 21 through the feed channel 232. Specifically, the feed channel 232 has a plurality of corresponding first trough bodies 211, and each of the feed channels 232 connects the pressing cavity with one of the first trough bodies 211.

[0035] To facilitate the movement of the second mold 2, a support rod 241 is provided on the outer side wall of the upper mold plate 24. The support rod 241 is used to connect to an external power device, which drives the upper mold plate 24 to move vertically to align with or move away from the first mold 1 through the support rod 241.

When placed, the template 5 is located in the first working area 11 aligned with the third working area 22.

[0037] First, the first silicone product is processed as follows: The upper mold cover plate 25 is lifted relative to the upper mold plate 24 using the second extension plate 251. Liquid silicone material is injected into the pressing cavity. The pressing plate 231 and the upper mold cover plate 25 are placed on the upper mold plate 24. The second mold 2 is lowered to align with the first mold 1. The first working area 11 and the second working area 21 now enclose a plurality of first processing cavities 3. The liquid silicone material is pressed into the first processing cavities 3 through the pressing plate 231 and the plurality of feed channels 232. This completes the production of the first silicone product.

[0038] The second mold 2 is moved upward to separate it from the first mold 1. The plug 143 is removed, and the lower mold plate 13 is rotated 180 degrees horizontally relative to the fixed platform 12. The first working area 11 containing the first silicone product and the third working area 22 are now aligned on the same vertical axis. The first positioning groove 141 is aligned and connected to the other second positioning groove 142. The plug 143 is inserted therein to secure the lower mold plate 13 to the fixed platform 12. The mold plate 5 located in the other first working area 11 is removed and placed in the first working area 11 aligned with the third working area 22. Solid silicone material is placed in this first working area 11. The second mold 2 is moved downward to align with the first mold 1. The first working area 11, the third working area 22, the mold plate 5, and the first silicone product now enclose a plurality of second processing cavities 4 corresponding to the second silicone products, enabling the silicone material to be processed into the second silicone products. Simultaneously, the first working area 11 aligned with the second working area 21 can continue to produce the first silicone product according to the above steps.
