[0019] Please see Figure 1-3This utility model provides a technical solution: a multi-size TOM molding auxiliary plate, including an upper mold frame 1 and a lower mold frame 2, wherein the upper mold frame 1 and the lower mold frame 2 are matched in position and size.

One end of the auxiliary rods 3 is fixedly connected to a mold core 4. A lower clamping plate 5 is provided on the upper side of the lower mold frame 2. The same sealing strip 11 is provided on the upper side of the lower clamping plate 5 and the lower side of the upper clamping plate 6. The sealing strip 11 is selected with a diameter of 6-12mm. A diaphragm 10 is provided between the upper clamping plate 6 and the lower clamping plate 5. A pad 13 is fixedly connected to one side of the upper mold frame 1. A fixing rod 14 is fixedly connected to one side of the pad 13. A rotating rod 15 is rotatably connected to one side of the pad 13. A spring 16 is provided between the rotating rod 15 and the fixing rod 14. A pad is fixedly connected to one side of the lower mold frame 2. 17. A fixing element 18 is fixedly connected to one side of the pad 17. The fixing element 18 is hollow inside. The internal gap size of the fixing element 18 is adapted to the distance between the fixing rod 14 and the rotating rod 15. A cylinder 20 is fixedly connected to one side of the pad 17. A telescopic rod 21 is provided on one side of the cylinder 20. The telescopic rod 21 passes through the fixing element 18. A push plate 23 is fixedly connected to one side of the telescopic rod 21. A positioning post 9 is provided on one side of the upper clamping plate 6. A guide sleeve 7 is provided on one side of the lower clamping plate 5. The positioning post 9 is adapted to the guide sleeve 7. Several fixing seats 8 are fixedly connected to one side of the upper clamping plate 6. Several support blocks 12 are provided on one side of the lower clamping plate 5. A gasket 24 is provided inside the fixing element 18. A protective pad 22 is provided on the surface of the rotating rod 15. A fixing rod 19 is fixedly connected to one side of the cylinder 20. The fixing rod 19 is fixedly connected to the surface of the lower mold frame 2.

[0020] Specifically, in the mold-closed state, the upper and lower mold frames and clamping plates are closed, and the diaphragm is positioned between the clamping plates. Under the action of the sealing strip, the upper and lower mold frames form two sealed, independent spaces. The upper and lower mold frames are simultaneously vacuumed. The rotating rod and fixing rod are pressed down along the upper mold frame and inserted into the gap of the fixing component. Due to the presence of the spring, the rotating rod is pushed outward by the spring. When pressed down, because the bottom of the rotating rod is inclined, it is pressed against the inclined surface by the inner wall of the fixing component, causing the entire rotating rod to fall into the gap inside the fixing component and be squeezed inward until it inserts into the bottom of the fixing component. Only then does the spring force cause it to engage at the corner of the inner wall of the fixing component. The protective pad and the gasket surface contact and have a certain frictional force, making the entire engagement stable. The cylinder and telescopic rod can push the push plate to push the rotating rod back to its original position. At this time, the mold can be pulled up to open. When fixed, the diaphragm 10 begins to heat and soften. Because it is in a vacuum state, the diaphragm can maintain a flat state during heating. Once the time and diaphragm surface temperature are reached, the upper mold frame 1 releases atmospheric pressure, creating a pressure difference that wraps the diaphragm 10 around the product. The lower mold frame 2 releases vacuum, balancing the pressure in the upper and lower cavities, opening the mold. The auxiliary mechanism lifts the transfer support block, removing the part. The upper clamping plate 6 is fitted with guide positioning pins 9 that cooperate with guide sleeves 7 for positioning. One end of the upper clamping plate 6 is connected to the upper clamping plate 6, and the other end is connected to the upper mold frame 1, making them a whole. According to the up-and-down movement of the equipment, the whole is in a sealed state when closed. The sealing strip model is selected with a diameter of 6-12mm. The selection is mainly based on the diaphragm size. Under the premise of ensuring the strength of the clamping plate, the largest diameter is selected to increase the contact area and improve airtightness. The inner ring forming area of ​​the upper and lower clamping plates and the contact surface with the diaphragm are machined with C-corner sections and rounded corners to avoid the film breaking and sharp corner scratches during the forming process. The structure is stable and the processing efficiency is high.
