[0038] A top plate 6, the top plate 6 is fixedly connected to the top outer wall of the base 1, and a hydraulic cylinder 7 is fixedly connected to the top outer wall of the top plate 6;

[0039] A fixing mechanism 3, the top outer wall of the base 1 is provided with a mounting mechanism 2 through the fixing mechanism 3, and the outer wall of the mounting mechanism 2 is provided with a hot pressing plate 5;

[0040] A dustproof mechanism 4, which is arranged in the inner wall of the base 1;

[0041] The mounting mechanism 2 includes a mounting block 201, and the inner wall of the mounting block 201 is elastically connected to a clamping block 203 via a connecting spring 202;

[0042] The fixing mechanism 3 includes a fixing plate 301, the outer wall of the fixing plate 301 is provided with a guide groove 302, and the inner wall of the guide groove 302 is slidably connected with a moving plate 305;

[0043] The dustproof mechanism 4 includes a wedge block 402 , which is elastically connected to the outer wall of the base 1 via a compression spring 401 .

[0044] The above scheme is adopted: the multi-layer fabric to be hot-pressed can be placed on the lower hot pressing plate 5, with both sides hanging down to the fixed plate 301, and its two ends are fixed and tightened by the fixing mechanism 3, and then it can be started by the hydraulic cylinder 7 to drive the mounting mechanism 2 set at its output end and the upper hot pressing plate 5 to move downward to perform hot pressing operation on the multi-layer fabric; the upper and lower groups of hot pressing plates 5 are both fixed by the mounting mechanism 2, and the mounting mechanism 2 can also facilitate the disassembly and installation of the hot pressing plates 5 so as to be replaced according to actual use requirements; multiple groups of heat dissipation ports are opened on the outer side of the base 1, and the heat dissipation ports can be opened for heat dissipation through the dustproof mechanism 4, and can also be closed when not in use to prevent dust and other impurities from entering and causing pollution, thereby affecting the heat dissipation effect.

[0045] like Figures 2 to 3 As shown, the inner wall of the mounting block 201 is slidably connected with a trapezoidal block 205, the inner wall of the mounting block 201 is slidably connected with a connecting rod 204, the outer wall of the hot pressing plate 5 is fixedly connected with an insert block 206, and the outer wall of the insert block 206 is provided with a slot 207; one end of the connecting spring 202 is fixedly connected to the outer wall of the block 203, the other end of the connecting spring 202 is fixedly connected to the inner wall of the mounting block 201, the block 203 is slidably connected to the inner wall of the mounting block 201, and the block 203 is engaged with the slot 207; one end of the connecting rod 204 is slidably connected to the outer wall of the trapezoidal block 205, and the other end of the connecting rod 204 is fixedly connected to the outer wall of the block 203.

[0046] The above scheme is adopted: two groups of connecting rods 204, clamping blocks 203 and connecting springs 202 are arranged, which are symmetrically distributed in the inner walls of the two sides of the mounting block 201, and when not affected by external forces, the connecting springs 202 will drive the clamping blocks 203 to remain in an outward pop-up state due to their own elastic force, so that the clamping blocks 203 drive one end of the corresponding connecting rod 204 to always contact the short side inclined surface of the trapezoidal block 205; one end of the trapezoidal block 205 passes through the outer wall of the mounting block 201, and the trapezoidal block 205 can be pressed to move toward the inner wall of the mounting block 201. During the movement, the inclined surface of the trapezoidal block 205 will squeeze the connecting rods 204 on both sides. The rod 204 is slidably connected to the inner wall of the mounting block 201 and can only move horizontally in its inner wall, so that the corresponding block 203 can be driven to move synchronously to both sides through the connecting rod 204, and move to the inner wall of the mounting block 201 to compress the connecting spring 202; at this time, the plug block 206 below the hot pressing plate 5 can be inserted into the mounting block 201, so that the position of the slot 207 corresponds to the position of the block 203, and the trapezoidal block 205 can be loosened. Under the elastic force of the connecting spring 202, the block 203 pops out and engages with the slot 207, and the fixing of the hot pressing plate 5 is completed. It is more convenient and does not need to be disassembled and installed by turning the bolts multiple times, saving time and effort.

[0047] like Figures 4 to 6As shown, the inner wall of the fixed plate 301 is slidably connected to the pull rod 303, the outer wall of the pull rod 303 is hinged to the movable plate 305 through the hinge rod 304, the inner wall of the movable plate 305 is elastically connected to the lower pressure plate 307 through the return spring 306, the outer wall of the pull rod 303 is provided with a groove 308, the outer wall of the fixed plate 301 is fixedly connected to the fixed block 309, and the inner wall of the fixed block 309 is elastically connected to the protrusion 311 through the telescopic spring 310.

[0048] The above scheme is adopted: multiple groups of grooves 308 are provided, which are horizontally distributed on the outer wall of the pull rod 303. The position of the pull rod 303 can be fixed by engaging the protrusion 311 with the groove 308, and the setting of multiple groups of grooves 308 can fix the pull rod 303 at multiple positions; the movable plate 305 and the hinge rod 304 are each provided with two groups, which are symmetrically distributed on the inner walls of both sides of the fixed plate 301. The movable plate 305 is slidably connected with the inner wall of the guide groove 302, so that it can only move along the inner wall of the guide groove 302. The wall moves laterally; when the operator pulls or pushes the pull rod 303, the pull rod 303 will drive the hinged rods 304 on both sides to flip, and the movable plate 305 can be driven to move laterally to both sides or the middle at the same time through the hinged rod 304; under normal circumstances, the protrusion 311 is always engaged with a group of grooves 308 due to the elastic force of the telescopic spring 310, and the long rod behind the protrusion 311 can be pulled to drive it to move to the fixed block 309 for aggregation, and the telescopic spring 310 can be compressed to release the limit of the pull rod 303 and move it.

[0049] like Figures 4 to 6 As shown, the fixed plate 301 is fixedly connected to the top outer wall of the base 1, the mounting block 201 is fixedly connected to the top outer wall of the fixed plate 301, one end of the reset spring 306 is fixedly connected to the inner wall of the movable plate 305, the other end of the reset spring 306 is fixedly connected to the outer wall of the lower pressure plate 307, and the lower pressure plate 307 is slidably connected in the inner wall of the movable plate 305; the two ends of the hinged rod 304 are hinged to the outer walls of the movable plate 305 and the pull rod 303 respectively, one end of the telescopic spring 310 is fixedly connected to the outer wall of the protrusion 311, the other end of the telescopic spring 310 is fixedly connected to the inner wall of the fixed block 309, the outer wall of the protrusion 311 is slidably connected to the inner wall of the fixed block 309, and the protrusion 311 is clamped with the groove 308.

[0050] The above scheme is adopted: when the multi-layer fabric is placed on the lower hot pressing plate 5, its two sides can be hung down and placed on the fixed plate 301, and the pull rod 303 is moved to adjust the position of the two sets of movable plates 305, so that the lower pressing plate 307 in the movable plate 305 corresponds to the position of the two sides of the multi-layer fabric, and the interface moves the lower pressing plate 307 upward to compress the return spring 306, and the two sides of the multi-layer fabric are placed under the lower pressing plate 307. At this time, the lower pressing plate 307 is driven to move downward by the elastic force of the return spring 306 itself, and the multi-layer fabric is pressed between the lower pressing plate 307 and the movable plate 305. When both sides of the multi-layer fabric are fixed, the multi-layer fabric is in a taut state, so that the pressure of the hot pressing plate 5 can be evenly distributed on the entire fabric surface, and there will be no local wrinkles or accumulation, which will affect the flatness and dimensional accuracy of the molding; and by adjusting the position of the movable plates 305 on both sides, it can adapt to multi-layer fabrics of different lengths, which is more flexible.

[0051] like Figure 7 As shown, the inner wall of the base 1 is slidably connected with a baffle 403, and the outer wall of the baffle 403 is fixedly connected with a shift block 404; one end of the compression spring 401 is fixedly connected to the outer wall of the wedge block 402, and the other end of the compression spring 401 is fixedly connected to the outer wall of the base 1; the wedge block 402 is slidably connected to the outer wall of the base 1, and the wedge block 402 contacts the outer wall of the shift block 404.

[0052] The above scheme is adopted: the outer wall of the baffle 403 is provided with a through groove corresponding to the size of the vent hole on the outer wall of the base 1, the baffle 403 can move up and down in the inner wall of the base 1, the shift block 404 passes through the outer wall of the base 1, and the baffle 403 can be driven to move by shifting the shift block 404; under normal conditions, the wedge block 402 is kept in a pop-up state due to the elastic force of the compression spring 401 itself, and the straight surface of the wedge block 402 is always facing upwards; when the operator shifts the shift block 404 upwards, the shift block 404 will squeeze the arc surface of the wedge block 402, so that it moves and compresses the compression spring 401, and the baffle 403 moves upward synchronously. Correspondingly, the shift block 404 is disengaged from the outer wall of the wedge block 402, and the wedge block 402 is ejected under the elastic force of the compression spring 401. At this time, its face is in contact with the outer wall of the shift block 404, and the shift block 404 is supported to maintain the position of the baffle 403, so that the vent can be opened to improve the heat dissipation effect; and by pressing the wedge block 402 to disengage from the shift block 404, the shift block 404 and the baffle 403 can be moved downward synchronously, and the outer wall groove of the baffle 403 is staggered with the position of the vent on the outer wall of the base 1, so that the vent can be closed to prevent dust and other impurities from entering the base. The structure is simple and the operation is convenient, and the problem of dust accumulation inside the equipment caused by the vent being open for a long time is avoided.

[0053] Embodiment 2

[0054] like Figures 8 to 9As shown, the inner wall of the trapezoidal block 205 is provided with a spring pin 8, the inner wall of the mounting block 201 is fixedly connected with a limit screw 9, and the inner wall of the limit screw 9 is elastically connected with a conical slider 10 through a sliding spring 11; one end of the sliding spring 11 is fixedly connected to the inner wall of the conical slider 10, and the other end of the sliding spring 11 is fixedly connected to the outer wall of the limit screw 9, and the conical slider 10 is slidably connected to the inner wall of the limit screw 9.

[0055] The above scheme is adopted: in order to solve the need to continuously press the trapezoidal block 205 when changing the mold and to ensure the safety of mold changing, a circular groove is provided in the trapezoidal block 205, and a spring latch 8 is elastically connected in the circular groove. The head of the spring latch is a 45° bevel, and the bevel faces the outside of the circular groove. The tails of the spring latches 8 on both sides of the circular groove are connected to the two ends of the electromagnetic valve, which is a prior art and is not shown in the figure; the electromagnetic valve controls the power switch of the hydraulic press equipment, and the spring latch 8 is an energized material; the internal thread of the mounting block 201 is connected to the limit screw 9, and the limit screw is provided with a hole, and the conical slider 10 slides in the hole and is elastically connected in the hole by the sliding spring 11; the bottom diameter of the conical slider 10 is slightly larger than the diameter of the limit screw 9 nail head; the edge of the limit screw 9 nail head is arc-shaped; when the sliding spring 11 is not under force, the conical slider 10 There is a 2mm gap with the head of the limit screw 9, and the limit screw is an energized material; when the trapezoidal block 205 is pressed for the first time, the spring latch 8 slides over the head of the limit screw 9, and when it is released, the spring latch 8 is stuck in the head of the limit screw 9, the trapezoidal block 205 remains in the pressed state, the blocking block 203 remains in the retracted state, the solenoid valve is energized, the hydraulic press equipment is powered off, and the workers can change molds safely; when the trapezoidal block 205 is pressed for the second time with a larger stroke, the spring latch 8 slides over the conical slider 10, and when it is released, the spring latch 8 drives the conical slider 10 to slide, and when the conical slider 10 can no longer move in the hole, the spring latch 8 slides on its own and breaks contact with the conical slider 10, the conical slider 10 resets, the spring latch 8 continues to pass over the head of the limit screw 9, the solenoid valve is powered off, and the hydraulic press equipment is powered on again.

[0056] The working principle and use process of the present invention:

[0057] The hot pressing plate 5 of suitable specifications is selected according to the actual needs of hot pressing multi-layer fabrics; if the hot pressing plate 5 needs to be replaced, the operator can press the trapezoidal block 205 on one side of the mounting block 201, and the trapezoidal block 205 moves toward the inner wall of the mounting block 201, and its inclined surface squeezes the connecting rods 204 on both sides, so that the connecting rods 204 drive the corresponding card blocks 203 to move synchronously to both sides and compress the connecting springs 202, and the card blocks 203 move to the inner wall of the mounting block 201; at this time, the original hot pressing plate 5 bottom plug block is pulled out from the mounting block 201, and then the selected hot pressing plate 5 bottom plug block 206 is inserted into the mounting block 201, so that the card slot 207 corresponds to the position of the card block 203, and the trapezoidal block 205 is loosened. Under the elastic force of the connecting spring 202, the card block 203 pops out and engages with the card slot 207, and the replacement of the hot pressing plate 5 is completed. The operation can be completed without turning the bolts multiple times, which is relatively convenient and quick.

[0058] When pressing the trapezoidal block 205, the spring latch 8 slides over the nail head of the limit screw 9, and the spring latch 8 is stuck on the nail head of the limit screw 9, so that the trapezoidal block 205 remains in the pressed state, the solenoid valve is energized, the hydraulic press equipment is powered off, and the workers can change the mold safely; after completion, the trapezoidal block 205 can continue to be pressed, and the spring latch 8 is stuck on the outer wall of the conical slider 10. When released, the spring latch 8 drives the conical slider 10 to slide in the hole of the limit screw 9. When the conical slider 10 can no longer move in the hole, the spring latch 8 is disengaged from the conical slider 10, and the conical slider 10 is reset. At this time, the spring latch 8 is not in contact with the nail head of the limit screw 9, thereby powering off the solenoid valve and restoring power to the hydraulic press equipment.

[0059] Then the multi-layer fabric to be hot-pressed can be placed on the lower hot pressing plate 5, so that the two sides of the fabric naturally hang down to the fixed plate 301, and then the long rod behind the protrusion 311 is pulled to release the limit of the pull rod 303, and the pull rod 303 is pulled or pushed. The pull rod 303 drives the hinged rods 304 on both sides to flip, and the hinged rods 304 drive the movable plate 305 to move horizontally to both sides or the middle along the inner wall of the guide groove 302, and the positions of the two groups of movable plates 305 are adjusted so that the lower pressure plate 307 in the movable plate 305 corresponds to the positions on both sides of the multi-layer fabric.

[0060] The lower pressure plate 307 is moved upward to compress the return spring 306, and the two sides of the multi-layer fabric are placed under the lower pressure plate 307. The elastic force of the return spring 306 drives the lower pressure plate 307 to move downward, and the multi-layer fabric is pressed between the lower pressure plate 307 and the movable plate 305. At this time, the multi-layer fabric is in a taut state; if the fixed position of the multi-layer fabric needs to be adjusted, the pull rod 303 can be adjusted again. The outer wall of the pull rod 303 has multiple groups of laterally distributed grooves 308. The protrusion 311 elastically connected by the telescopic spring 310 on the inner wall of the fixing block 309 of the fixing plate 301 is clamped with the grooves 308 at different positions, so that the pull rod 303 can be fixed at different positions, thereby realizing the fixed adjustment of different positions of the multi-layer fabric.

[0061] After the multi-layer fabric is fixed, the hydraulic cylinder 7 can be started. The output end of the hydraulic cylinder 7 drives the mounting mechanism 2 fixed thereon and the upper hot pressing plate 5 to move downward, and the multi-layer fabric in a taut state is subjected to hot pressing operation. During the hot pressing process, the pressure of the hot pressing plate 5 is evenly distributed on the entire fabric surface, ensuring the flatness and dimensional accuracy of the hot pressing molding of the multi-layer fabric, and avoiding local wrinkles or accumulation problems.

[0062] When the device needs to dissipate heat during operation, the shift block 404 that passes through the outer wall of the base 1 is moved upward, driving the baffle 403 to move upward synchronously, and the shift block 404 squeezes the arc surface of the wedge block 402, so that the wedge block 402 moves and compresses the compression spring 401; when the outer wall groove of the baffle 403 corresponds to the position of the vent on the outer wall of the base 1, the shift block 404 is out of contact with the outer wall of the wedge block 402, and the wedge block 402 pops up under the elastic force of the compression spring 401, and its straight face contacts the outer wall of the shift block 404, supporting the shift block 404 to maintain the position of the baffle 403, and the vent is opened, thereby improving the heat dissipation effect of the equipment.

[0063] When the device is not in use or does not need to dissipate heat, press the wedge block 402 to disengage it from the shift block 404, and the shift block 404 and the baffle 403 move downward synchronously. The outer wall groove of the baffle 403 is staggered with the position of the vent on the outer wall of the base 1, and the vent is closed to prevent dust and other impurities from entering the base, and to avoid the vent being opened for a long time to cause dust accumulation inside the device.
