Description

Technical Field

[0001] The present invention relates to the technical field of rubber - coated molding equipment, and particularly to a rubber - coated molding die for medical polymer materials and its usage method. Background Technique

[0002] With the development of medical science, medical fixation materials are also constantly evolving. Shape - memory polymer materials are a type of intelligent material that can respond to external conditions. They can "remember" a set shape (original shape) and then be molded into various required shapes (temporary shapes). When external temperature, magnetic field, humidity, light, etc. reach specific conditions, they can automatically return to the original shape. Shape - memory polymer materials have many advantages such as easy shaping, large deformation amount, adjustable response temperature, printable, light weight, and low cost, and have broad application prospects in the fields of biomedicine, aerospace, intelligent textiles, sensors, and self - repair. In recent years, people have begun to use shape - memory polymer materials to prepare new medical fixation materials. The general process is to place the substrate of medical polymer composite material in the center of the bottom die of the molding die, cover the top die, and clamp it via a fixture. Then, inject the prepared silicone or other flexible materials through the injection hole. After placing for about 3 hours, separate the top die and the bottom die, and take out the substrate to achieve the rubber - coating molding of the polymer composite material.

[0003] Among them, when injecting the rubber - coating solution into the mold, the stacking of the solutions may enclose external air inside the solution, resulting in small bubbles remaining inside the solution. When the remaining bubbles cool and form, it will seriously affect the rubber - coating effect of the object. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above - mentioned technical problems, the present invention provides a rubber - coated molding die for medical polymer materials, including a processing mechanism. The processing mechanism further includes an equipment base. A housing is fixedly connected to the side wall of the equipment base. An electric telescopic rod is fixedly connected to the side wall of the housing. A push column is fixedly connected to the end of the electric telescopic rod away from the housing. A piston plate is fixedly connected to the end of the push column away from the electric telescopic rod.

[0005] A pressure - relief mechanism. The pressure - relief mechanism includes a feed groove opened on the side wall of the push square plate. A sliding baffle is slidably connected to the inner wall of the feed groove. A push square plate is fixedly connected to the side wall of the sliding baffle. A fixed plate is fixedly connected to the end of the push square plate away from the sliding baffle. A first reset spring is fixedly connected to the bottom of the fixed plate. An L - shaped frame one is slidably connected to the side wall of the push square plate. The end of the first reset spring away from the fixed plate is fixedly connected to the top of the L - shaped frame one. The end of the L - shaped frame one away from the push square plate is fixedly connected to the top of the piston plate.

[0006] Demolding mechanism, the demolding mechanism includes a fixed square plate fixedly connected to the inner wall of the equipment base. A first slider is fixedly connected to the side wall of the fixed square plate. A slide rail is slidably connected to the outer wall of the first slider. A sliding square rod is fixedly connected to the side wall of the slide rail. A second slider is fixedly connected to the side wall of the sliding square rod. The outer wall of the second slider is slidably connected to the inner wall of another slide rail. The outer wall of the second slider is slidably connected to the bottommost plate.

[0007] Preferably, the processing mechanism further includes a solution chute opened on the inner wall of the equipment base. A conveying groove is opened on the side wall of the solution chute. A sliding block is slidably connected to the inner wall of the solution chute. A pressing square rod is fixedly connected to the bottom of the sliding block. A mounting plate is fixedly connected to the end of the pressing square rod away from the sliding block. A pulling spring is fixedly connected to the top of the pressing square rod. Taking advantage of the characteristic that high-pressure defoaming can remove bubbles inside the solution, a piston plate is provided inside the equipment. Before the present invention is used, the staff places the solution glue to be processed through the feeding groove on the top of the bottommost plate and turns on the power supply of the electric telescopic rod. At this time, the electric telescopic rod drives the piston plate into the inner part of the housing through the pushing column. During the downward movement of the piston plate, the piston plate drives the pushing square plate to move downward through the first L-shaped frame. The pushing square plate drives the sliding baffle to block the feeding groove, making the housing form a closed space. During this process, the piston plate enters the inner wall of the housing and forms a sealed piston state. As the piston plate continues to press down, the space between the bottom of the piston plate and the inner part of the housing will be under high pressure. At this time, the solution on the top of the bottommost plate is affected by the high-pressure environment, and the gas inside the solution will be greatly squeezed by the external pressure, resulting in the rupture of the solution wall outside the bubble. Through the application of the above components, the bubbles remaining in the mold and the colloid are effectively removed.

[0008] Preferably, the processing mechanism further includes an output pipe fixedly connected to the inner wall of the equipment base. An extrusion frame is fixedly connected to the top of the sliding block. A cooling plate is fixedly connected to the side wall of the equipment base.

[0009] Preferably, the pressure relief mechanism further includes a second L-shaped frame slidably connected to the inner wall of the through hole of the fixed plate. A deflation groove is opened on the top of the piston plate. A sliding frame is fixedly connected to the inner wall of the sliding block. A piston block is slidably connected to the inner wall of the sliding frame. A fixed column is fixedly connected to the top of the piston block, and a pressing plate is fixedly connected to the top of the fixed column. A central shaft plate is fixedly connected to the top of the piston plate. After the stamping is completed, the electric telescopic rod will drive the piston plate to continue to move downward. At this time, the second L-shaped frame will move downward synchronously. When the bottom of the protruding block of the second L-shaped frame contacts the top of the fixed plate, the second L-shaped frame will drive one end of the prying plate to move upward, presenting as Figure 7In the shown state, the other end of the prying plate drives the fixed column and the piston block to move downward along the inner wall of the sliding frame through the pressing plate, causing a dislocation between the piston block and the air release groove and forming a pressure relief gap. At this time, the high-pressure gas at the bottom of the piston plate will be discharged outward along this gap, converting the high-pressure gas at the bottom of the piston plate into normal air pressure. During this process, since the high-pressure gas converts to low pressure, it will absorb the heat in the sealed environment. Through the application of the above components, after the equipment finishes encapsulation, using the characteristic of temperature reduction during the conversion from high pressure to low pressure, the temperature inside the equipment will gradually decrease, and this cooling is used to accelerate the cooling efficiency inside the equipment.

[0010] Preferably, the pressure relief mechanism further includes a prying plate rotatably connected to the side wall of the middle shaft plate. The side wall of the prying plate is slidably connected to the side wall of the pressing plate. The end of the prying plate away from the pressing plate is fixedly connected to the bottom of the second L-shaped frame. A pushing spring is fixedly connected to the bottom of the piston block.

[0011] Preferably, the demolding mechanism further includes a sealing slide plate slidably connected to the inner wall of the sliding baffle. A pressure-receiving column is fixedly connected to the bottom of the sealing slide plate. An expansion bladder is connected through the side wall of the sliding baffle. Using the characteristic that the piston plate drives the pushing square plate to move downward, where the pushing square plate is slidably connected to the first L-shaped frame. When the pushing square plate drives the sliding baffle to block the feeding groove, the pressure-receiving column will contact the inner wall of the feeding groove, and the reaction force generated by the pressure-receiving column will push the sealing slide plate to move upward along the inner wall of the sliding baffle, causing the solution inside the sliding baffle to enter the expansion bladder, causing the expansion bladder to expand. When the expansion bladder expands, the expansion bladder is on the inner wall of the feeding groove, and the expanded expansion bladder will block the gap between the sliding baffle and the feeding groove, improving the sealing performance of the outer shell, ensuring the sealing effect of the outer shell under the high-pressure environment of the equipment, and preventing pressure relief and affecting the defoaming effect.

[0012] Preferably, the demolding mechanism further includes a push rod slidably connected to the inner wall of the output pipe. A sliding plate is fixedly connected to the side wall of the push rod. One end of the push rod away from the sliding plate is fixedly connected to a second return spring. The end of the second return spring away from the push rod is fixedly connected to the inner wall of the output pipe. By using the restriction of the high-pressure environment formed at the bottom of the piston plate, a sliding block is arranged inside the device. When the device generates a high-pressure environment, the high pressure will generate a force that spreads around. This force will act on the top of the sliding block, causing the sliding block to move downward along the inner wall of the solution chute. As the sliding block moves downward, it will push the solution inside the solution chute and enter the bottom of the fixed square plate through the conveying chute. As the solution at the bottom of the fixed square plate increases, the expansion force of the solution will push the sliding square rod and the second slider to move upward along the inner wall of the slide rail, and finally make several sliding square rods in a horizontal state. In addition, as the solution at the bottom of the fixed square plate increases, it will act on the side of the push rod through the output pipe, causing the sliding plate to move outward. During this process, the extrusion frame moves downward and extrudes and forms the solution glue on the top of the bottom plate. After the processing is completed, the electric telescopic rod drives the piston plate to reset, the high-pressure gas at the bottom of the piston plate disappears, and the sliding block, the sliding square rod, the bottom plate, and the sliding plate reset, making the above components away from the product that has been encapsulated with glue. Through the application of the above components, a deformable outer shell is formed inside the mold, improving the subsequent demolding efficiency.

[0013] A method for using a medical polymer material encapsulation mold includes the following steps:

[0014] S1: Before use, the staff places the solution glue to be processed on the top of the bottom plate through the feeding groove and turns on the power supply of the electric telescopic rod;

[0015] S2: The electric telescopic rod drives the piston plate into the inner part of the outer shell through the push column. During the downward movement of the piston plate, the piston plate drives the pushing square plate to move downward through the first L-shaped frame, and the pushing square plate drives the sliding baffle to block the feeding groove, making the outer shell form a closed space;

[0016] S3: The piston plate enters the inner wall of the outer shell and forms a sealed piston state. As the piston plate continues to press down, the space between the bottom of the piston plate and the inner part of the outer shell will be compressed to generate a high-pressure environment.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the characteristic that high-pressure defoaming can remove the bubbles inside the solution. A piston plate is provided inside the device. Before use, the staff places the device on the round hole on the side wall of the device base through the feeding groove, places the solution glue to be processed on the top of the bottom plate, and turns on the power supply of the electric telescopic rod. At this time, the electric telescopic rod drives the piston plate into the inner part of the housing through the pushing column. During the downward movement of the piston plate, the piston plate drives the pushing square plate to move downward through the L-shaped frame 1, and the pushing square plate drives the sliding baffle to block the feeding groove, making the housing form a sealed space. In this process, the piston plate enters the inner wall of the housing and forms a sealed piston state. As the piston plate continues to press down, the space between the bottom of the piston plate and the inner part of the housing will be under high pressure. At this time, the solution on the top of the bottom plate is affected by the high-pressure environment, and the gas inside the solution will be greatly squeezed by the external pressure, resulting in the rupture of the solution wall outside the bubble. Through the application of the above components, the bubbles remaining in the glue inside the mold are effectively removed.

[0019] (2) The present invention utilizes the limitation of the high-pressure environment formed at the bottom of the piston plate. A sliding block is provided inside the device. When the device generates a high-pressure environment, the high pressure will generate a force that spreads around, and this force will act on the top of the sliding block, causing the sliding block to move downward along the inner wall of the solution chute. As the sliding block moves downward, it will push the solution inside the solution chute into the bottom of the fixed square plate through the conveying groove. As the solution at the bottom of the fixed square plate increases, the expanding force of the solution will push the sliding square rod and the slider 2 to move upward along the inner wall of the slide rail, and finally make several sliding square rods in a horizontal state. In addition, as the solution at the bottom of the fixed square plate increases, it will act on the side of the push rod through the output pipe, causing the sliding plate to move outward. In this process, the extrusion frame moves downward and extrudes the solution glue on the top of the bottom plate into shape. After the processing is completed, the electric telescopic rod drives the piston plate to reset, the high-pressure gas at the bottom of the piston plate disappears, and the sliding block, the sliding square rod, the bottom plate, and the sliding plate reset, making the above components move away from the product that has completed encapsulation. Through the application of the above components, a deformable housing is formed inside the mold, improving the subsequent demolding efficiency.

[0020] (3) The present invention utilizes the characteristic that the piston plate drives the pushing square plate to move downward. The pushing square plate is slidably connected to the L-shaped frame 1. When the pushing square plate drives the sliding baffle to block the feeding groove, the pressure column will contact the inner wall of the feeding groove, and the reaction force generated by the pressure column will push the sealing slide plate to move upward along the inner wall of the sliding baffle, making the solution inside the sliding baffle enter the expansion bladder, causing the expansion bladder to expand. When the expansion bladder expands, the expansion bladder is on the inner wall of the feeding groove, and the expanded expansion bladder will block the gap between the sliding baffle and the feeding groove, improving the sealing performance of the housing and ensuring the sealing effect of the housing under the high-pressure environment of the device, avoiding pressure relief and affecting the defoaming effect.

[0021] (4) After the stamping of the present invention is completed, the electric telescopic rod will drive the piston plate to continue to move downward. At this time, the second L-shaped frame will move downward synchronously. When the bottom of the protruding block of the second L-shaped frame contacts the top of the fixed plate, the second L-shaped frame will drive one end of the prying plate to move upward, presenting a state as shown in Figure 7 . The other end of the prying plate drives the fixed column and the piston block to move downward along the inner wall of the sliding frame through the pressing plate, causing the piston block to be misaligned with the air release groove and forming a pressure relief gap. At this time, the high-pressure gas at the bottom of the piston plate will be discharged outward along this gap, causing the high-pressure gas at the bottom of the piston plate to change to normal air pressure. During this process, since the high-pressure gas changes to low pressure, it will absorb the heat in the sealed environment. Through the application of the above components, after the equipment completes encapsulation, by utilizing the characteristic of reducing temperature from high pressure to low pressure, the temperature inside the equipment will gradually decrease, and the cooling efficiency inside the equipment will be accelerated by using this cooling method.

One end of the first reset spring 205 away from the fixing plate 204 is fixedly connected to the top of the L-shaped frame 206. One end of the L-shaped frame 206 away from the pushing square plate 203 is fixedly connected to the top of the piston plate 105;

[0039] Demolding mechanism 3, the demolding mechanism 3 includes a fixed square plate 301 fixedly connected to the inner wall of the equipment base 101. A first slider 302 is fixedly connected to the side wall of the fixed square plate 301. The outer wall of the first slider 302 is slidably connected to a slide rail 304. A sliding square rod 303 is fixedly connected to the side wall of the slide rail 304. A second slider 305 is fixedly connected to the side wall of the sliding square rod 303. The outer wall of the second slider 305 is slidably connected to the inner wall of another slide rail 304. The outer wall of the second slider 305 is slidably connected to the bottommost plate 306.

[0040] The processing mechanism 1 further includes a solution chute 106 opened on the inner wall of the equipment base 101. A conveying groove 107 is opened on the side wall of the solution chute 106. A sliding block 108 is slidably connected to the inner wall of the solution chute 106. A pressing square rod 109 is fixedly connected to the bottom of the sliding block 108. One end of the pressing square rod 109 away from the sliding block 108 is fixedly connected to a mounting plate 110. A pulling spring 111 is fixedly connected to the top of the pressing square rod 109. By utilizing the characteristic that high-pressure defoaming can remove the bubbles inside the solution, a piston plate 105 is provided inside the equipment. Before the present invention is used, the staff places the solution glue to be processed on the top of the bottommost plate 306 through the feeding groove 201 and turns on the power supply of the electric telescopic rod 103. At this time, the electric telescopic rod 103 drives the piston plate 105 into the interior of the housing 102 through the pushing column 104. Among them, during the downward movement of the piston plate 105, the piston plate 105 drives the pushing square plate 203 to move downward through the L-shaped frame 206. The pushing square plate 203 drives the sliding baffle 202 to block the feeding groove 201, making the housing 102 form a sealed space. In this process, the piston plate 105 enters the inner wall of the housing 102 and forms a sealed piston state. As the piston plate 105 continues to press downward, the space between the bottom of the piston plate 105 and the interior of the housing 102 will be under high pressure. At this time, the solution on the top of the bottommost plate 306 is affected by the high-pressure environment, and the gas inside the solution will be greatly squeezed by the external pressure, resulting in the solution wall outside the bubble being unable to withstand the pressure and bursting. Through the application of the above components, the bubbles remaining in the mold and the colloid are effectively removed.

[0041] The processing mechanism 1 further includes an output pipe 113 fixedly connected to the inner wall of the equipment base 101. A pressing frame 112 is fixedly connected to the top of the sliding block 108, and a cooling plate 114 is fixedly connected to the side wall of the equipment base 101.

[0042] Example 2. Please refer to Figure 6 - Figure 11 This invention is a medical polymer material encapsulation molding die. On the basis of Example 1, the pressure relief mechanism 2 further includes an L-shaped frame two 207 slidably connected to the inner wall of the through hole of the fixed plate 204. A pressure relief groove 208 is formed at the top of the piston plate 105. A sliding frame 209 is fixedly connected to the inner wall of the sliding block 108. A piston block 210 is slidably connected to the inner wall of the sliding frame 209. A fixed column 211 is fixedly connected to the top of the piston block 210, and a pressing plate 212 is fixedly connected to the top of the fixed column 211. A central axis plate 213 is fixedly connected to the top of the piston plate 105. After the stamping is completed, the electric telescopic rod 103 will drive the piston plate 105 to continue to move downward. At this time, the L-shaped frame two 207 will move downward synchronously. When the bottom of the protruding block of the L-shaped frame two 207 contacts the top of the fixed plate 204, the L-shaped frame two 207 will drive one end of the lever plate 214 to move upward, presenting a state as shown in Figure 7 As shown. The other end of the lever plate 214 drives the fixed column 211 and the piston block 210 to move downward along the inner wall of the sliding frame 209 through the pressing plate 212, causing the piston block 210 to be misaligned with the pressure relief groove 208 and forming a pressure relief gap. At this time, the high-pressure gas at the bottom of the piston plate 105 will be discharged outward along this gap, causing the high-pressure gas at the bottom of the piston plate 105 to change to normal air pressure. During this process, since the high-pressure gas changes to low pressure, it will absorb the heat in the sealed environment. Through the application of the above components, after the equipment completes encapsulation, by using the characteristic of reducing temperature from high pressure to low pressure, the temperature inside the equipment will gradually decrease, and the cooling efficiency inside the equipment will be accelerated by using this cooling.

[0043] The pressure relief mechanism 2 further includes a lever plate 214 rotatably connected to the side wall of the central axis plate 213. The side wall of the lever plate 214 is slidably connected to the side wall of the pressing plate 212. The end of the lever plate 214 away from the pressing plate 212 is fixedly connected to the bottom of the L-shaped frame two 207. A pushing spring 215 is fixedly connected to the bottom of the piston block 210.

[0044] The demolding mechanism 3 further includes a sealing slide plate 307 slidably connected to the inner wall of the sliding baffle 202. A pressure-receiving column 308 is fixedly connected to the bottom of the sealing slide plate 307. An expansion bladder 309 is connected through the side wall of the sliding baffle 202. Taking advantage of the feature that the piston plate 105 drives the pushing square plate 203 to move downward, wherein the pushing square plate 203 is slidably connected to the first L-shaped frame 206. When the pushing square plate 203 drives the sliding baffle 202 to block the feeding groove 201, the pressure-receiving column 308 will contact the inner wall of the feeding groove 201. The reaction force generated by the pressure-receiving column 308 will push the sealing slide plate 307 to move upward along the inner wall of the sliding baffle 202, so that the solution inside the sliding baffle 202 enters the expansion bladder 309, causing the expansion bladder 309 to expand. When the expansion bladder 309 expands, the expansion bladder 309 is located on the inner wall of the feeding groove 201. The expanded expansion bladder 309 will block the gap between the sliding baffle 202 and the feeding groove 201, improving the sealing performance of the outer shell 102, ensuring the sealing effect of the outer shell 102 under the high-pressure environment of the equipment, and avoiding pressure relief, which affects the defoaming effect.

[0045] The demolding mechanism 3 further includes a push rod 310 slidably connected to the inner wall of the output pipe 113. A sliding plate 311 is fixedly connected to the side wall of the push rod 310. One end of the push rod 310 away from the sliding plate 311 is fixedly connected to a second return spring 312. The end of the second return spring 312 away from the push rod 310 is fixedly connected to the inner wall of the output pipe 113. Taking advantage of the limitation of the high-pressure environment formed at the bottom of the piston plate 105 above, a sliding block 108 is arranged inside the equipment. When the equipment generates a high-pressure environment, the high pressure will generate a force that diffuses in all directions. This force will act on the top of the sliding block 108, causing the sliding block 108 to move downward along the inner wall of the solution chute 106. As the sliding block 108 moves downward, it will push the solution inside the solution chute 106 to enter the bottom of the fixed square plate 301 through the conveying groove 107. As the solution at the bottom of the fixed square plate 301 increases, the expansion force of the solution will push the sliding square rod 303 and the second slider 305 to move upward along the inner wall of the slide rail 304, and finally make several sliding square rods 303 in a horizontal state. In addition, as the solution at the bottom of the fixed square plate 301 increases, it will act on the side of the push rod 310 through the output pipe 113, causing the sliding plate 311 to move outward. During this process, the extrusion frame 112 moves downward and extrudes and shapes the solution glue on the top of the bottom plate 306. After the processing is completed, the electric telescopic rod 103 drives the piston plate 105 to reset, and the high-pressure gas at the bottom of the piston plate 105 disappears. The sliding block 108, the sliding square rod 303, the bottom plate 306, and the sliding plate 311 are reset, causing the above components to move away from the product with the completed rubber coating. Through the application of the above components, a deformable outer shell is formed inside the mold, improving the subsequent demolding efficiency.

[0046] The usage method of this rubber coating device includes the following steps:

[0047] S1: Before use, the staff place the solution glue to be processed on the top of the bottom plate 306 through the feeding trough 201 and turn on the power supply of the electric telescopic rod 103;

[0048] S2: The electric telescopic rod 103 drives the piston plate 105 into the interior of the housing 102 through the push column 104. During the downward movement of the piston plate 105, the piston plate 105 drives the push square plate 203 to move downward through the L-shaped frame one 206, and the push square plate 203 drives the sliding baffle 202 to block the feeding trough 201, so that the housing 102 forms a sealed space;

[0049] S3: The piston plate 105 enters the inner wall of the housing 102 and forms a sealed piston state. As the piston plate 105 continues to press down, the space between the bottom of the piston plate 105 and the interior of the housing 102 will be under pressure to generate a high-pressure environment.

[0050] A specific application of this embodiment is as follows: Before using the present invention, the staff place the solution glue to be processed on the top of the bottom plate 306 through the feeding trough 201 and turn on the power supply of the electric telescopic rod 103. At this time, the electric telescopic rod 103 drives the piston plate 105 into the interior of the housing 102 through the push column 104. During the downward movement of the piston plate 105, the piston plate 105 drives the push square plate 203 to move downward through the L-shaped frame one 206, and the push square plate 203 drives the sliding baffle 202 to block the feeding trough 201, so that the housing 102 forms a sealed space. During this process, the piston plate 105 enters the inner wall of the housing 102 and forms a sealed piston state. As the piston plate 105 continues to press down, the space between the bottom of the piston plate 105 and the interior of the housing 102 will be under pressure to generate a high-pressure environment. At this time, the solution on the top of the bottom plate 306 is affected by the high-pressure environment, and the gas inside the solution will be greatly squeezed by the external pressure, resulting in the rupture of the solution wall outside the bubble. Through the application of the above components, the air bubbles remaining in the glue inside the mold are effectively removed.

[0051] Taking advantage of the limitation of forming a high-pressure environment at the bottom of the above-mentioned piston plate 105, a sliding block 108 is provided inside the device. When a high-pressure environment is generated in the device, the high pressure will generate a force that diffuses in all directions. This force will act on the top of the sliding block 108, causing the sliding block 108 to move downward along the inner wall of the solution chute 106. As the sliding block 108 moves downward, it will push the solution inside the solution chute 106, and the solution will enter the bottom of the fixed square plate 301 through the conveying chute 107. As the solution at the bottom of the fixed square plate 301 increases, the expansion force of the solution will push the sliding square rod 303 and the second slider 305 to move upward along the inner wall of the slide rail 304, and finally make several sliding square rods 303 in a horizontal state. In addition, as the solution at the bottom of the fixed square plate 301 increases, it will act on the side of the push rod 310 through the output pipe 113, causing the sliding plate 311 to move outward. During this process, the extrusion frame 112 moves downward and squeezes the solution glue on the top of the bottom plate 306 to form a shape. After the processing is completed, the electric telescopic rod 103 drives the piston plate 105 to reset, and the high-pressure gas at the bottom of the piston plate 105 disappears. The sliding block 108, the sliding square rod 303, the bottom plate 306, and the sliding plate 311 are reset, causing the above components to move away from the product that has been coated with glue. Through the application of the above components, a deformable outer shell is formed inside the mold, improving the subsequent demolding efficiency. Taking advantage of the characteristic that the piston plate 105 drives the pushing square plate 203 to move downward, where the pushing square plate 203 is slidably connected to the first L-shaped frame 206. When the pushing square plate 203 drives the sliding baffle 202 to block the feeding groove 201, the pressure receiving column 308 will contact the inner wall of the feeding groove 201, and the reaction force generated by the pressure receiving column 308 will push the sealing slide plate 307 to move upward along the inner wall of the sliding baffle 202, causing the solution inside the sliding baffle 202 to enter the expansion bladder 309, causing the expansion bladder 309 to expand. When the expansion bladder 309 expands, the expansion bladder 309 is located on the inner wall of the feeding groove 201, and the expanded expansion bladder 309 will block the gap between the sliding baffle 202 and the feeding groove 201, improving the sealing performance of the outer shell 102, ensuring the sealing effect of the outer shell 102 under the high-pressure environment of the device, and preventing pressure relief, which may affect the defoaming effect.

[0052] After the stamping is completed, the electric telescopic rod 103 will drive the piston plate 105 to continue moving downward. At this time, the second L-shaped frame 207 will move downward synchronously, and when the bottom of the protruding block of the second L-shaped frame 207 contacts the top of the fixed plate 204, the second L-shaped frame 207 will drive one end of the lever plate 214 to move upward, presenting as Figure 7In the shown state, the other end of the lever plate 214 drives the fixed column 211 and the piston block 210 to move downward along the inner wall of the sliding frame 209 through the pressing plate 212, causing the piston block 210 to be misaligned with the air release groove 208 and forming a pressure relief gap. At this time, the high-pressure gas at the bottom of the piston plate 105 will be discharged outward along this gap, making the high-pressure gas at the bottom of the piston plate 105 transform into normal air pressure. During this process, since the high-pressure gas transforms into low-pressure gas, it will absorb the heat in the sealed environment. Through the application of the above components, after the equipment finishes encapsulation, by utilizing the characteristic of the high-pressure to low-pressure conversion to reduce the temperature, the temperature inside the equipment will gradually decrease, and this cooling is used to accelerate the cooling efficiency inside the equipment.
