[0021] 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a die-cutting device for processing insulating thermally conductive silicone sheets, including a base 1, a support 2, a die-cutting fixed mold 3, and a die cutter 7. The support 2 is installed on the top of the base 1, and the die-cutting fixed mold 3 is slidably connected to the top of the base 1. Four guide pillars 4 are fixedly connected to the top of the base 1 and the top of the inner wall of the support 2, and a cylinder 6 is fixedly installed on the top of the support 2. A transmission component 5 is inserted into the outside of the four guide pillars 4, and the die cutter 7 is installed at the bottom of the transmission component 5. A cutting seat 8 is inserted into the inside of the transmission component 5; the middle of the cutting seat 8 is open The cutter 8 has a slot 9, a buffer assembly 10 is installed at the bottom of the cutter 8, and upper connecting blocks 51 are installed at both the front and rear ends of the transmission component 5. The cutter 8 has first lower connecting ears 81 installed at both the left and right ends. A rotating seat 54 and two limiting rods 56 are fixedly installed at the bottom of the upper connecting block 51. A stud 55 is rotatably connected inside the rotating seat 54. A sleeve 83 is installed in the middle of the first lower connecting ear 81. The stud 55 passes through the first lower connecting ear 81 and is sleeved inside the sleeve 83. The inner wall of the first lower connecting ear 81 has a circular hole for inserting the two limiting rods 56.
[0023] The upper connecting block 51 and the first lower connecting ear 81 can be installed respectively via the transmission component 5 and the cutting seat 8. Since the top of the bracket 2 is fixedly equipped with a cylinder 6, the cutting seat 8 is inserted into the transmission component 5, and a buffer assembly 10 is installed at the bottom of the cutting seat 8. A rotating seat 54 and two limiting rods 56 are fixedly installed at the bottom of the upper connecting block 51. A stud 55 is rotatably connected inside the rotating seat 54. A sleeve 83 is installed in the middle of the first lower connecting ear 81, and the stud 55 passes through the first lower connecting ear 81 and is sleeved inside the sleeve 83. The inner wall of the die has a circular hole for inserting two limiting rods 56. By rotating the stud 55, under the action of the sleeve 83, the circular hole in the inner wall of the first lower connecting ear 81 moves along the two limiting rods 56. Since the two first lower connecting ears 81 are fixedly installed at the left and right ends of the cutting seat 8, and the middle of the cutting seat 8 has a slot 9, the length of the die cutter 7 extending outward along the slot 9 can be adjusted. This allows the die cutter 7 to cut thermally conductive silicone sheets of different thicknesses without damaging the die-cutting mold 3, saving time and effort, and improving processing efficiency.
[0024] See Figure 1 , Figure 2 Four insert rods 82 are fixedly installed on the top of the cutting seat 8. All four insert rods 82 are inserted into the inner wall of the transmission component 5. The inner wall of the transmission component 5 is provided with four sliding grooves 52 with the same outer diameter as the four guide posts 4. The inner wall of the transmission component 5 is also provided with four guide grooves 53 with the same outer diameter as the four insert rods 82. The die cutter 7 passes through the slot 9 and the buffer assembly 10. The output end of the cylinder 6 passes through the bracket 2 and is fixedly connected to the top of the transmission component 5.
[0025] The four insert rods 82 can be installed through the cutting seat 8. Since the inner wall of the transmission component 5 has four sliding grooves 52 and four guide grooves 53 with the same outer diameter as the four guide posts 4 and the four insert rods 82, when the length of the die cutter 7 is adjusted by rotating the stud 55, the cutting seat 8 drives the four insert rods 82 to slide along the four guide grooves 53, which can ensure the stability of the cutting seat 8 when it moves. The output end of the cylinder 6 passes through the bracket 2 and is fixedly connected to the top of the transmission component 5, so that the die cutter 7 passes through the slot 9 and the buffer assembly 10. When the cylinder 6 is activated to push the transmission component 5 to drive the die cutter 7 to die cut the thermally conductive silicone sheet, the buffer assembly 10 can contact the thermally conductive silicone sheet and form a reaction force on it, which can prevent the die cutter 7 from being damaged by excessive impact force.
[0026] See Figure 1 , Figure 4The buffer assembly 10 includes a buffer plate 101 and two upper connecting ears 102. The two upper connecting ears 102 are respectively installed at the front and rear ends of the cutting seat 8. The front and rear ends of the buffer plate 101 are equipped with second lower connecting ears 103. The top of each of the two second lower connecting ears 103 is equipped with a slide rod 104. The two slide rods 104 are inserted into the two upper connecting ears 102. The inner wall of the buffer plate 101 is provided with a through groove 105. The die cutter 7 is located at the upper end of the through groove 105. The top of each of the two second lower connecting ears 103 is fixedly connected with a spring 106. The other end of each spring 106 is fixedly connected to the bottom of the two upper connecting ears 102. The inner wall of the through groove 105 is equipped with a sponge 11. The two upper connecting ears 102 and the two second lower connecting ears 103 are symmetrical.
[0027] The second lower connecting ear 103 can be installed through the buffer plate 101 in the buffer assembly 10. Since the two upper connecting ears 102 are respectively installed at the front and rear ends of the cutting seat 8, and the two upper connecting ears 102 and the two second lower connecting ears 103 are symmetrical, the inner wall of the buffer plate 101 is provided with a through groove 105. A sponge 11 is installed on the inner wall of the through groove 105, so that anti-sticking agent is dripped into the sponge 11. When the transmission component 5 drives the die cutter 7 to move downward, the buffer plate 101 is in contact with the thermally conductive silicone sheet. The spring 106 elastically acts... When the die cutter 7 passes through the through groove 105, it enters the mold edge of the thermally conductive silicone sheet. At this time, the anti-stick agent in the sponge 11 will be applied to the surface of the die cutter 7, which can prevent the thermally conductive silicone sheet from sticking to the die cutter 7. When the thermally conductive silicone sheet is molded, the cutter seat 8 moves down, and the compressible spring 106 causes the buffer plate 101 and the two second lower connecting ears 103 to form a reaction force, which can prevent the excessive impact force of the die cutter 7 from damaging the thermally conductive silicone sheet. At the same time, when the buffer plate 101 is reset, the die cutter 7 is located in the through groove 105, which can also protect the cutter head of the die cutter 7.
[0028] During operation, the upper connecting block 51 and the first lower connecting ear 81 can be installed via the transmission component 5 and the cutting seat 8, respectively. Since a cylinder 6 is fixedly installed on the top of the bracket 2, the cutting seat 8 is inserted into the transmission component 5, and a buffer assembly 10 is installed at the bottom of the cutting seat 8. A rotating seat 54 and two limiting rods 56 are fixedly installed at the bottom of the upper connecting block 51. A stud 55 is rotatably connected inside the rotating seat 54. A sleeve 83 is installed in the middle of the first lower connecting ear 81, and the stud 55 passes through the first lower connecting ear 81 and is sleeved inside the sleeve 83. The inner wall of 81 has a circular hole for inserting two limiting rods 56. By rotating the stud 55, under the action of the sleeve 83, the circular hole in the inner wall of the first lower connecting ear 81 moves along the two limiting rods 56. Since the two first lower connecting ears 81 are fixedly installed at the left and right ends of the cutting seat 8, and the middle of the cutting seat 8 has a slot 9, the length of the die cutter 7 extending outward along the slot 9 can be adjusted. This allows the die cutter 7 to die cut thermal conductive silicone sheets of different thicknesses without damaging the die-cutting mold 3, saving time and effort, and improving processing efficiency.
[0029] The four insert rods 82 can be installed through the cutting seat 8. Since the inner wall of the transmission component 5 has four sliding grooves 52 and four guide grooves 53 with the same outer diameter as the four guide posts 4 and the four insert rods 82, when the length of the die cutter 7 is adjusted by rotating the stud 55, the cutting seat 8 drives the four insert rods 82 to slide along the four guide grooves 53, which can ensure the stability of the cutting seat 8 when it moves. The output end of the cylinder 6 passes through the bracket 2 and is fixedly connected to the top of the transmission component 5, so that the die cutter 7 passes through the slot 9 and the buffer assembly 10. When the cylinder 6 is activated to push the transmission component 5 to drive the die cutter 7 to die cut the thermally conductive silicone sheet, the buffer assembly 10 can contact the thermally conductive silicone sheet and form a reaction force on it, which can prevent the die cutter 7 from being damaged by excessive impact force.
[0030] The second lower connecting ear 103 can be installed through the buffer plate 101 in the buffer assembly 10. Since the two upper connecting ears 102 are respectively installed at the front and rear ends of the cutting seat 8, and the two upper connecting ears 102 and the two second lower connecting ears 103 are symmetrical, the inner wall of the buffer plate 101 is provided with a through groove 105. A sponge 11 is installed on the inner wall of the through groove 105, so that anti-sticking agent is dripped into the sponge 11. When the transmission component 5 drives the die cutter 7 to move downward, the buffer plate 101 is in contact with the thermally conductive silicone sheet. The spring 106 elastically acts... When the die cutter 7 passes through the through groove 105, it enters the mold edge of the thermally conductive silicone sheet. At this time, the anti-stick agent in the sponge 11 will be applied to the surface of the die cutter 7, which can prevent the thermally conductive silicone sheet from sticking to the die cutter 7. When the thermally conductive silicone sheet is molded, the cutter seat 8 moves down, and the compressible spring 106 causes the buffer plate 101 and the two second lower connecting ears 103 to form a reaction force, which can prevent the excessive impact force of the die cutter 7 from damaging the thermally conductive silicone sheet. At the same time, when the buffer plate 101 is reset, the die cutter 7 is located in the through groove 105, which can also protect the cutter head of the die cutter 7.
[0031] In summary, by rotating the stud 55, the device causes the first lower connecting lug 81 to drive the cutting seat 8 to move along the two limit rods 56 and the transmission component 5 under the action of the sleeve 83. This allows for adjustment of the length of the die cutter 7 extending outward along the slot 9, which not only saves time and effort but also improves processing efficiency.
