[0022] This invention discloses a hot-pressing and trimming device for fluorosilicone rubber.

[0024] Furthermore, the bearing unit 1 includes: Base 11; Support cabinet 12, which is fixedly connected to base 11; The support platform 13 is fixedly connected to the base 11 and is located below the first connecting plate 22 and the second connecting plate 24. The bottom of the support platform 13 is provided with a discharge channel for collecting small pieces of fluorosilicone rubber after trimming.

[0025] Furthermore, a guide rail 111 and a slide rail 112 are fixedly connected to the base 11, with the slide rail 112 located inside the guide rail 111.

[0026] Furthermore, the first slide block 21 is slidably connected to the slide rail 112; The second slide block 23 is slidably connected to the guide rail 111.

[0027] Furthermore, the feeding unit 2 also includes: Positioning plate 25, two positioning plates 25 are provided, and the two positioning plates 25 are respectively installed on the first connecting plate 22 and the second connecting plate 24; Linear motor 27 is mounted on base 11, and the output end of linear motor 27 is fixedly connected to the second slide 23.

[0028] Furthermore, the positioning plate 25 has multiple through holes 251; The positioning plate 25 is provided with a pressing groove 252; The positioning plate 25 has multiple insertion holes 253.

[0029] Furthermore, the transmission assembly 28 includes: The first rack 281 is fixedly connected to the second slide 23; Gear 282 meshes with the first rack 281 and is rotatably connected to the base 11; The second rack 283 meshes with the gear 282 and is fixedly connected to the first slide 21. The fluorosilicone rubber to be trimmed is placed on the positioning plate 25, and the rotating flip plate 42 presses and positions the rubber on the positioning plate 25. When the first connecting plate 22 and the second connecting plate 24 need to be interchanged, the hydraulic cylinder 26 is activated, causing the second connecting plate 24 to rise. Then, the linear motor 27 is activated, driving the second slide 23 to slide along the guide rail 111. Simultaneously, through the meshing transmission of the first rack 281, gear 282, and second rack 283 in the transmission assembly 28, the first slide 21 slides along the slide rail 112. The first slide 21 and the second slide 23 move towards each other. When the second slide 23 moves below the trimming unit 3, the hydraulic cylinder 26 reverses and drives the second connecting plate 24 to descend and settle, achieving simultaneous material loading and trimming, ensuring continuous trimming and greatly improving production efficiency.

[0030] Furthermore, trimming unit 3 includes: The stamping cylinder 31 is fixedly connected to the support cabinet 12; The movable plate 32 is fixedly connected to the output end of the stamping cylinder 31.

The plug rods 344 are inserted into the plug hole 253. Spring 345 is sleeved on the insertion rod 344. When the fluorosilicone rubber moves below the trimming unit 3, the stamping cylinder 31 is activated, which drives the moving plate 32 to move downward along the guide rod 33, and the trimming assembly 34 moves downward accordingly. The trimming block 343 is movably inserted into the through hole 251 on the positioning plate 25 to trim the edge of the fluorosilicone rubber and squeeze the fluorosilicone rubber product to detach from the whole fluorosilicone rubber; the insertion rod 344 is inserted into the insertion hole 253, which plays a positioning and guiding role; the spring 345 plays a buffering role during the trimming process, and the spring 345 presses the pressure plate 341 to keep the pressure plate 341 pressing the fluorosilicone rubber to ensure the stability of the trimming.

[0032] Example 2: According to the appendix Figure 1-6 As shown, a fluorosilicone rubber hot pressing molding and trimming device includes: Bearing unit 1; Feeding unit 2 is mounted on bearing unit 1 and includes: First slide 21; The first connecting plate 22 is fixedly connected to the top of the first slide block 21; The second slide 23 is disposed outside the first slide 21; The second connecting plate 24 is movably disposed on the top of the second slide block 23; Hydraulic cylinder 26 is mounted on the second slide block 23, and the output end of hydraulic cylinder 26 is fixedly connected to the second connecting plate 24. Transmission assembly 28 is disposed between the first slide 21 and the second slide 23, and is used for the first slide 21 and the second slide 23 to move toward each other; Trimming unit 3 is positioned above feeding unit 2; Auxiliary unit 4 is located in front of feeding unit 2 and is used for rapid positioning of fluorosilicone rubber.

[0033] Furthermore, auxiliary unit 4 includes: Fixing block 41 is located in front of the support platform 13 and is fixedly connected to the base 11; The flip plate 42 is rotatably connected to the top of the fixed block 41; Two limiting blocks 43 are provided, and the two limiting blocks 43 are fixedly connected to both sides of the fixing block 41 respectively. The limiting blocks 43 are used to limit the position of the flip plate 42. The rotatable flip plate 42 allows the fluorosilicone rubber to be squeezed and quickly positioned on the positioning plate 25, avoiding the complicated operation of manual pressing and positioning, and improving the trimming efficiency.

[0034] Working principle: Place the fluorosilicone rubber to be trimmed on the positioning plate 25, and press and position the fluorosilicone rubber on the positioning plate 25 by rotating the flip plate 42. When the first connecting plate 22 and the second connecting plate 24 need to be interchanged, the hydraulic cylinder 26 is activated to lift the second connecting plate 24. Then, the linear motor 27 is activated, which drives the second slide block 23 to slide along the guide rail 111. At the same time, through the meshing transmission of the first rack 281, gear 282 and the second rack 283 in the transmission assembly 28, the first slide block 21 slides along the slide rail 112. The first slide block 21 and the second slide block 23 move towards each other. When the second slide block 23 moves to the bottom of the trimming unit 3, the hydraulic cylinder 26 drives the second connecting plate 24 to descend and fall into place in the opposite direction. This realizes simultaneous feeding and trimming, ensuring continuous trimming and greatly improving production efficiency. When the fluorosilicone rubber moves to the bottom of the trimming unit 3, the stamping cylinder 31 is activated. The stamping cylinder 31 drives the moving plate 32 to move downward along the guide rod 33, and the trimming assembly 34 moves downward accordingly. The trimming block 343 is movably inserted into the through hole 251 on the positioning plate 25 to trim the edge of the fluorosilicone rubber and squeeze the fluorosilicone rubber product to fall off from the whole fluorosilicone rubber. The detached fluorosilicone rubber falls into the discharge channel below the support platform 13 for subsequent collection. The insertion rod 344 is inserted into the insertion hole 253, which plays a positioning and guiding role. The spring 345 plays a buffering role during the trimming process, and on the other hand, the spring 345 squeezes the pressure plate 341 to keep the pressure plate 341 pressing the fluorosilicone rubber to ensure the stability of the trimming. After trimming is completed, the stamping cylinder 31 drives the moving plate 32 upward, and the trimming assembly 34 resets. Then, the hydraulic cylinder 26 is activated, causing the second connecting plate 24 to rise. Next, the linear motor 27 moves in the opposite direction, driving the first slide block 21 and the second slide block 23 to slide in the opposite direction. When the second connecting plate 24 resets, the first connecting plate 22 moves below the trimming unit 3, removing the trimmed fluorosilicone rubber from the positioning plate 25 on the second connecting plate 24, and reloading. Simultaneously, the next loading and trimming can be performed, achieving continuous production.
