Description

Technical Field

[0001] The invention relates to the technical field of vacuum hot pressing machines, and in particular to a fully automated vacuum hot pressing machine and method. Background Art

[0002] Vacuum heat press is a processing equipment that heats the material to a certain temperature and then applies high pressure to form the material into the desired shape and structure in the mold.

[0003] Before hot pressing multi-layer materials, the vacuum hot press machine needs to evacuate the built-in chamber to a vacuum state. However, the existing vacuum hot press machine lacks positioning and fixing equipment for the multi-layer materials. If the multi-layer materials to be hot pressed are light in weight, the gas in the chamber will be extracted during the vacuum pumping process of the hot press machine to form an airflow. This airflow usually acts directly on the multi-layer hot-pressed materials, causing them to be subjected to uneven force, thereby causing shaking. When the multi-layer materials are offset due to shaking, the hot pressing effect of the vacuum hot press machine will be affected. At the same time, the existing vacuum hot press machine lacks cooling equipment. After the multi-layer materials are hot-pressed, they will adhere to the mold. When demolding is required, it is usually necessary to wait for them to cool to a lower temperature to solidify and shrink and separate from the mold. Demolding can only be performed without adhesion to the mold. However, the waiting time for natural cooling is long, which affects the hot pressing efficiency of the entire vacuum hot press machine.

[0019] Example 1: Please refer to Figure 1 - Fig.15 , a fully automated vacuum hot press machine, comprising an equipment body 1 and a suction pipe 10 connected and arranged inside the equipment body 1, a vacuum suction machine is arranged inside the suction pipe 10, a chamber door is arranged on the outside of the equipment body 1, the inner side wall of the equipment body 1 is fixedly connected with a mold 7, a hydraulic telescopic rod 4 is arranged on the outside of the equipment body 1, a hot pressing plate 3 is arranged at the end of the hydraulic telescopic rod 4, a plurality of sliding grooves are opened on the side wall of the hot pressing plate 3, the inner side walls of the plurality of sliding grooves are all slidably connected with a pressing horizontal plate 6, a pressing spring 5 is fixedly connected on the outer side wall of the pressing horizontal plate 6, and one end of the pressing spring 5 away from the pressing horizontal plate 6 is fixedly connected to the inner side wall of the sliding groove, a positioning mechanism is arranged inside the equipment body 1, the positioning mechanism comprises a plurality of slide rails 8 arranged inside the equipment body 1, the inner side walls of the plurality of slide rails 8 are all slidably connected with a sleeve ring 28, a square plate 25 is arranged on the slide rail 8, and a tension spring 26 is arranged between the square plate 25 and the sleeve ring 28.

[0020] The inner side wall of the collar 28 is slidably connected with a positioning plate 27 , and a tension spring is provided on the positioning plate 27 , and the other end of the tension spring is fixedly connected to the outer side wall of the collar 28 .

[0021] The inner wall of the slide rail 8 is slidably connected with a trigger plate 29, and a pressure spring 30 is arranged on the trigger plate 29. The other end of the pressure spring 30 is fixedly connected to the outer wall of the slide rail 8. The ends of the positioning plate 27 and the trigger plate 29 are both provided with trigger magnets, and the magnetic poles of the two trigger magnets are opposite. A cooling mechanism is arranged inside the device body 1.

[0022] The cooling mechanism includes a side box 47 arranged on the side wall of the equipment body 1, the side box 47 is connected to the air outlet 2, the air outlet 2 is provided with a solenoid valve, the side box 47 is connected to the cooling pipe 14, the cooling pipe 14 is fixedly connected to the inside with a cross bar, the outer wall of the cross bar is fixedly connected to the driving motor 15, the output end of the driving motor 15 is provided with a transmission rod 57, the end of the transmission rod 57 is provided with a fan 13, and the outer wall of the transmission rod 57 is fixedly connected to the friction wheel 17.

[0023] In the present embodiment, when in use, the operator can first place the multi-layer materials that need to be hot-pressed on the hot pressing plate 3 in sequence. When the multi-layer materials are placed, the operator can first pull up the multiple positioning plates 27 in sequence, and then lower the positioning plates 27 to make them close to the surface of the multi-layer materials under the tension of the tension spring 26. When the multiple positioning plates 27 are fixed to the four corners of the multi-layer materials in sequence, the operator can flip and close the chamber door, and then use the vacuum suction machine inside the suction pipe 10 to suck the air inside the equipment body 1 to suck the inside into a vacuum state. When the inside of the equipment body 1 is in a vacuum state, the hot pressing plate 3 can be moved down by the hydraulic telescopic rod 4. When the hot pressing plate 3 moves down, the multiple pressing horizontal plates 6 on the hot pressing plate 3 will contact and press the corresponding trigger plate 29, allowing the trigger plate 29 to overcome the The elastic force of the pressure spring 30 moves toward the inside of the slide rail 8. When the trigger magnet at the bottom of the trigger plate 29 moves down to the positive side of the end of the positioning plate 27, since the end of the positioning plate 27 is also provided with a trigger magnet, the magnetic force of the two trigger magnets attracting each other will cause the positioning plate 27 to move toward the inside of the slide rail 8 and break away from the contact with the multi-layer material. When the positioning plate 27 breaks away from the multi-layer material, the hot pressing plate 3 will continue to move downward to perform vacuum hot pressing on the multi-layer material on the mold 7 (this is the prior art and will not be elaborated on in detail). The four corners of the placed multi-layer material will be pressed and fixed by multiple positioning plates 27 to ensure that when the suction tube 10 is vacuumed inside the equipment body 1 through the vacuum suction machine, the multi-layer material will not be affected by the airflow and will not be displaced on the mold 7, thereby ensuring the hot pressing effect of the equipment.

[0027] A water tank 31 is provided on the side wall of the equipment body 1. A water pipe 32 is provided inside the water tank 31. A plurality of branch pipes 48 are provided on the water pipe 32. The plurality of branch pipes 48 are respectively connected to the interior of the corresponding bellows 40. A wind wheel 49 is rotatably connected to the end of the branch pipe 48. The interior of the wind wheel 49 is hollow. A through hole is provided inside the wind wheel 49. The through hole is connected to the interior of the branch pipe 48. A plurality of liquid ejection holes 50 are provided on the wind wheel 49. The interiors of the plurality of liquid ejection holes 50 are all fixedly connected with inner connecting plates 53. A liquid sprinkling port 54 is provided inside the inner connecting plate 53. A bracket 51 is fixedly connected to the outer wall of the inner connecting plate 53.

[0028] A rotating rod 37 is rotatably connected to the outer wall of the side box 47, a belt 16 is sleeved between the rotating rod 37 and the transmission rod 57, a turntable 43 is sleeved on the rotating rod 37, a plurality of limiting grooves 44 are provided on the inner wall of the plurality of limiting grooves 44, a pushing magnet 42 is slidably connected to the inner walls of the plurality of limiting grooves 44, the magnetic poles of the pushing magnet 42 are the same as the magnetic poles of the magnetic plate 39, a tension spring 38 is provided at the tail of the pushing magnet 42, and an end of the tension spring 38 away from the pushing magnet 42 is provided on the inner wall of the limiting groove 44.

[0029] In this embodiment, after the multilayer material is hot-pressed, the operator can flip open the chamber door. Since the equipment body 1 has a certain amount of heat after hot-pressing, when the heat is conducted to the inside of the pressing cylinder 9 through the heat-conducting tube 11, the mercury inside the pressing cylinder 9 will undergo thermal expansion reaction (it should be noted that the heat-conducting tube 11 is made of brass material and has a strong thermal conductivity). When the mercury inside the pressing cylinder 9 undergoes thermal expansion reaction, it will overcome the elastic force of the inner retraction spring 56 and push the push rod 21 downward for a long distance. When the push rod 21 moves downward for a long distance, the arc-shaped contact plate 19 will first contact the surface of the friction wheel 17. Then, as the push rod 21 continues to push downward, the inner plate 24 inside the arc-shaped contact plate 19 will also move downward to contact the push rod 21. The arc-shaped contact plate 19 and the inner plate 24 are both made of frosted material. When the three are in contact, there is a strong friction force. At this time, the operator can turn on the drive motor 15 to drive the fan 13 to rotate through the transmission rod 57. Under the action of the large friction force, the transmission rod 57 will drive the fan 13 to rotate slowly. When the push rod 21 moves down a large distance, it will also drive the slide tube 22 to move down synchronously, so that the two side holes 23 originally located inside the ventilation pipe 12 are exposed outside the ventilation pipe 12. At this time, the hot air in the equipment body 1 will pass through the ventilation pipe 12 and then through the two side holes 23 into the cooling pipe 14, mix with the cold air blown out by the fan 13, blow into the side box 47, and finally blow to the connection between the mold 7 and the molded multi-layer material through the guide of the air nozzle 2.

[0030] With the continuous air jetting from the air jet 2 and the heat exchange and cooling of the multiple water-cooling tubes 35, the temperature inside the equipment body 1 will slowly decrease. At this time, the heat conducted from the heat-conducting tube 11 to the pressing cylinder 9 will decrease accordingly, and the expansion coefficient of mercury will also decrease accordingly. At this time, under the elastic force of the retraction spring 56, the push rod 21 will slightly move upward into the pressing cylinder 9. When the push rod 21 moves upward, it will drive the inner plate 24 in the arc-shaped contact plate 19 to move upward synchronously and break away from the contact with the friction wheel 17. When the inner plate 24 breaks away from the contact with the friction wheel 17, the friction area in contact with the friction wheel 17 will decrease, and the friction force exerted on the friction wheel 17 will also decrease accordingly. When the power of the driving motor 15 is constant, the friction force exerted on the friction wheel 17 becomes smaller, and the driving motor 15 is driven to rotate at a constant speed. The motor 15 will drive the fan 13 to rotate at medium speed. When the fan 13 rotates at medium speed, the cold air blown out will increase compared with before. When the push rod 21 moves up, the fan 13 rotates at medium speed and at the same time, the slide pipe 22 will be driven to move up synchronously, so that one of the two side holes 23 of the ventilation pipe 12 originally exposed outside moves back into the ventilation pipe 12. When one of the two side holes 23 moves back into the ventilation pipe 12, the hot air in the equipment body 1 conducted by the ventilation pipe 12 will only be blown into the cooling pipe 14 through one side hole 23, and mixed with the cold air blown out by the fan 13. At this time, the mixed wind will be lower in temperature than before, and the wind with lowered temperature will continue to be blown to the connection between the mold 7 and the molded multi-layer material through the guide of the air nozzle 2.

[0031] When the temperature of the air in the device body 1 continues to decrease under the heat exchange and cooling of the multiple water-cooling tubes 35, as in the above principle, when the heat conducted by the heat-conducting tube 11 is insufficient, the mercury expansion coefficient in the pressing tube 9 will decrease again. At this time, the push rod 21 will continue to move upward under the elastic force of the retracted spring 56, driving the arc contact plate 19 to break away from the contact with the friction wheel 17. When the arc contact plate 19 is no longer in contact with the friction wheel 17, the friction force on the friction wheel 17 disappears, and the transmission rod 57 will drive the fan 13 to rotate rapidly. The upward movement of the push rod 21 drives the arc-shaped contact plate 19 to break away from the contact with the friction wheel 17, and at the same time drives the slide tube 22 to move upward synchronously, so that the two side holes 23 can all enter the interior of the slide tube 22, and the ventilation pipe 12 no longer mixes hot air into the cooling pipe 14. At this time, the cold air blown out by the rapid rotation of the fan 13 will be lower in temperature again than before. By performing staged air spray cooling on the connection between the mold 7 and the molded multi-layer material, not only the demolding speed of the molded multi-layer material can be improved, but also stress cracking inside the molded multi-layer material due to excessive cooling speed can be avoided.

[0032] When the arc-shaped contact plate 19 is out of contact with the friction wheel 17, under the action of the above principle, the transmission rod 57 will rotate rapidly, and driven by the belt 16, the rotating rod 37 and the turntable 43 will be synchronously driven to rotate. At this time, under the action of centrifugal force, the pushing magnet 42 will overcome the pulling force of the tension spring 38 and move to the outside of the limiting groove 44, and the pushing magnet 42 located outside the limiting groove 44 will approach the magnetic plate 39. At this time, under the action of the repulsive magnetic force, the magnetic plate 39 will push the baffle 46 to move into the bellows 40, allowing the through hole 45 originally located outside the bellows 40 to enter the bellows 40. When the fan 13 rotates rapidly to blow air into the side box 47, part of the wind will enter the bellows 40. At this time, the wind entering the bellows 40 The wind will drive the wind wheel 49 to rotate. When the wind wheel 49 rotates, the centrifugal force generated will cause the blocking plug 55 to overcome the elastic force of the blocking spring 52 and be thrown out of the liquid sprinkling port 54. When the blocking plug 55 no longer blocks the liquid sprinkling port 54, the water transported to the inside of the wind wheel 49 by the branch pipe 48 will be thrown to the outside of the wind wheel 49 through the liquid throwing hole 50, mixed with the wind blown out of the bellows 40, and enter the cooling box 34 through the air jet pipe 41 to cool the heat-conducting fins 36. The wind mixed with cooling water droplets has a lower temperature, which can further cool the heat-conducting fins 36, so that the heat-conducting fins 36 can better conduct the heat carried by the coolant in the water-cooling pipe 35, thereby increasing the cooling speed of the water-cooling pipe 35 on the equipment body 1.

[0033] A method for using a fully automated vacuum hot press, the method comprising the following steps: S1: When in use, the multi-layer materials to be hot-pressed are placed on the hot-pressing plate 3 in sequence. When the multi-layer materials are placed, the positioning mechanism fixes the four corners of the multi-layer materials; S2: After the position of the multilayer material is fixed, the chamber door is turned over and closed, and the vacuum suction machine inside the suction pipe 10 sucks the air inside the equipment body 1 to make the inside of the equipment body 1 into a vacuum state; S3: When the interior of the equipment body 1 is in a vacuum state, the hot pressing plate 3 is moved downward by the hydraulic telescopic rod 4. When the hot pressing plate 3 moves downward, the multi-layer material is hot pressed; S4: After the multi-layer material is hot-pressed, the connection between the molded multi-layer material and the mold 7 will be cooled down in stages to increase the demoulding speed of the molded multi-layer material.

[0034] It should be noted that when the arc-shaped contact plate 19 contacts the friction wheel 17, the transmission rod 57 will rotate slower under the friction force of the friction wheel 17. Therefore, driven by the belt 16, the rotation speed of the turntable 43 will also be slower. The centrifugal force generated at this time is not enough to throw the push magnet 42 to the outside of the turntable 43. At this time, the bellows 40 will not ventilate the air jet pipe 41. The water-cooling pipe 35 inside the corresponding cooling box 34 will only rely on the circulating coolant inside the water-cooling pipe 35 to cool the inside of the equipment body 1. Compared with the additional external cooling by air jet in the later stage, the cooling rate inside the equipment body 1 will be relatively low, thereby avoiding a faster cooling rate inside the equipment body 1 and affecting the entire formed multi-layer material.

[0035] It should be noted that the water tank 31 will transport the cooling water to the wind wheel 49 through the water pipe 32 and the branch pipe 48 .

[0036] It should be noted that a ceramic coating is applied to the bottom of the positioning plate 27, and the ceramic coating is relatively smooth. After the positioning plate 27 is pressed and the multi-layer material is pulled away, the friction between the relatively smooth ceramic coating and the multi-layer material is relatively small, and the multi-layer material will not be pulled apart together. In addition, the ceramic coating is resistant to high temperatures and will not decompose under high temperature hot pressing.

[0037] It should be noted that when the multi-layer material in the device body 1 is heat-pressed, the air outlet 2 and the electromagnetic valve in the ventilation pipe 12 are closed and will not ventilate to the outside.
