Description

Technical Field

[0001] The invention relates to the technical field of regulating valve processing, and in particular to a thermoforming mechanism for regulating valve parts. Background Art

[0002] In the manufacturing process of regulating valve parts, the thermoforming mechanism is a key processing equipment. However, the existing thermoforming mechanism has many shortcomings in practical application, which seriously affects the production efficiency and product quality.

[0003] First of all, conventional thermoforming mechanisms are usually only equipped with one mold for injection molding, which means that only one component can be produced in each injection molding cycle. This single-mold injection molding method greatly limits production efficiency and cannot meet the needs of large-scale, high-efficiency production. With the increasingly fierce market competition, improving production efficiency has become the key to improving the competitiveness of enterprises.

[0004] Secondly, the existing thermoforming mechanism has inconveniences in unloading. The injection molded parts often need to be manually removed from the mold, which not only increases the labor intensity, but may also cause the parts to be damaged or deformed during the removal process. In addition, the manual unloading method is difficult to ensure the consistency and accuracy of unloading, further affecting product quality and production efficiency.

[0005] Finally, the existing thermoforming mechanism is unable to detect the air tightness of the mold, which is one of the important factors to ensure the quality of injection molding. If there is an air leakage problem in the mold, the plastic melt will not be able to fully fill the mold cavity during the injection molding process, thereby affecting the dimensional accuracy and surface quality of the parts. However, the current thermoforming mechanism lacks effective air tightness detection means and cannot promptly detect and deal with the air leakage problem of the mold during the production process.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the cooperation between the V-shaped rod and the moving assembly, during the process of the V-shaped rod rotating to the right, the inclined plate gradually becomes inclined, the electric push rod actively extends, and cooperates with the four guide rods to complete the pushing of the material, and cooperates with the gradually inclined inclined plate to generate a pushing force for the material to the outside. At the same time, under the inclined slope of the inclined plate and the action of gravity, the shaped material is smoothly and quickly discharged, and intermittent injection and discharge of the two groups of first molds and second molds are realized, thereby improving the injection efficiency of the device and reducing the influence of cooling and shaping on the processing efficiency.

[0018] 2. At the beginning of the rotation of the V-shaped rod, the two first molds do not contact the front side wall of the vertical plate, and the horizontal rod on the right begins to contact the baffle on the right. First, close the second solenoid valve on the right, and the gas inside the rectangular cylinder begins to enter the first mold and the second mold. The gas is blown out from the injection port on the rear side of the first mold to clean the impurities inside the first mold and the second mold and the injection port.

[0019] 3. In the middle of the rotation of the V-shaped rod, the first mold on the left begins to contact the front wall of the vertical plate, blocking the rear injection port of the first mold. The gas in the rectangular tube continues to enter the first mold and the second mold. During this process, the air pressure sensor identifies the internal air pressure. If it is identified that the air pressure is not continuously increasing, it indicates that a gap has occurred between the first mold and the second mold. The first mold and the second mold should be replaced and repaired.

[0020] 4. At the end of the rotation of the V-shaped rod, the second solenoid valve on the left is closed, and the second solenoid valve on the right is opened. The gas inside the rectangular cylinder begins to enter the guide rod on the right. As the electric push rod extends, the guide rod will extend inside the second mold. At the same time, under the action of air pressure, the cylindrical plate is further pushed outward to push the material for the second time, and the distance of pushing the material is increased, ensuring that the molded parts can be demolded at one time, and the parts can be quickly unloaded in cooperation with the inclined plate.

An injection tube 106 is provided at the front end of 105, a base 102 is provided at the front end of the support platform 103, a vertical plate 107 is provided at the top rear side of the base 102, a V-shaped rod 204 is provided at the top front side of the base 102, a moving assembly is provided at the rear side of the V-shaped rod 204, a first mold 302 and a second mold 304 are provided at the rear end of the moving assembly, the V-shaped rod 204 cooperates with the moving assembly to drive the first mold 302 and the second mold 304 to move, the rear end of the first mold 302 cooperates with the front end of the injection tube 106, the injection tube 106 is a part of the injection molding host 105, responsible for injecting molten plastic material into the first mold 302, then the first mold 302 and the second mold 304 are cooled, the molten material inside can be cooled, and then the reciprocating rotation of the V-shaped rod 204 is cooperated to complete the loading and unloading of the two groups of the first mold 302 and the second mold 304, thereby improving the work efficiency, the first mold 302 and the second mold 304 are provided with cooling water channels inside, and the cooling circulating water pipe can be connected (this is the prior art, not shown in the figure).

[0038] A moving plate 403 is provided at the bottom of the moving component. As the V-shaped rod 204 swings, the moving plate 403 can be driven to move left and right through the moving component. A box body 501 is provided on the top of the moving plate 403. When the moving plate 403 moves left and right, the box body 501 is driven to move.

Through the cooperation of the moving component and the control component, the box body 501 is moved and the inclined plate 502 is tilted at the same time, so that the cooled material can be transferred. At the same time, the inclined inclined plate 502 facilitates the falling of the material.

[0039] Two hoses 608 are provided at the bottom of the control component. The two hoses 608 are arranged symmetrically with the center line of the box body 501 as the symmetry axis. A connecting plate 306 is provided on the top of each hose 608. The gas generated by the control component passes through the hose 608 to the inside of the connecting plate 306. The connecting plate 306 and the guide rod 305 are hollow. A plurality of guide rods 305 are arranged on the circumference of the rear side of the connecting plate 306. The guide rod 305 is connected to the second mold 304. The guide rod 305 slides inside the second mold 304. The movement of the guide rod 305 can push the material out of the second mold 304. A cylindrical plate 309 is provided at the rear end of the guide rod 305. The guide rod 305 enters the high pressure The gas will further push the cylindrical plate 309 to move backward to ensure the effect of material discharge. A second spring 308 is provided at the front end of the cylindrical plate 309. The front end of the second spring 308 is connected to the guide rod 305. When the air pressure inside the guide rod 305 returns to normal, the cylindrical plate 309 is driven to reset under the pulling force of the second spring 308 to prevent the material from entering the guide rod 305 during the injection molding process. An air pressure sensor is provided inside the guide rod 305, and the air pressure sensor can monitor the air pressure changes inside the guide rod 305 in real time. A first spring 307 is provided at the front end of the second mold 304, and the first spring 307 can provide power for the reset of the connecting plate 306.

[0040] A worm wheel 203 is provided at the front end of the bottom of the V-shaped rod 204, and a worm 202 is meshed at the top of the worm wheel 203. A motor 201 is provided on the right side of the worm 202. The bottom of the motor 201 is connected to the base 102. When the motor 201 is started, the rotational power outputted by the motor 201 is directly transmitted to the worm 202. During the rotation of the worm 202, the spiral tooth surface of the worm wheel 203 pushes the tooth surface of the worm wheel 203, so that the worm wheel 203 generates a rotational motion, thereby driving the V-shaped rod 204 to rotate. At the same time, the worm wheel 203 and worm 202 transmission system has a unique self-locking ability, that is, when the worm 202 stops rotating, the worm wheel 203 cannot rotate by itself under the action of load.

[0041] The moving assembly includes two cylindrical rods 205, which are arranged symmetrically with the center line of the V-shaped rod 204 as the symmetry axis. The outer ends of the V-shaped rod 204 are respectively slidably connected to the cylindrical rods 205. The rear side of the V-shaped rod 204 is provided with a guide rail 206. The bottom of the guide rail 206 is connected to the base 102. The cylindrical rod 205 passes through the guide rail 206. The cylindrical rod 205 passes through the V-shaped rod 204 and the guide rail 206. The through holes in the V-shaped rod 204 and the guide rail 206 are aligned with the straight holes of the cylindrical rod 205. The cylindrical rod 205 has the same diameter, which can ensure that the cylindrical rod 205 can slide inside the V-shaped rod 204 and the guide rail 206. A slider 208 is provided at the rear end of the cylindrical rod 205. A vertical slider 207 is slidably connected to the outer side of the slider 208. The bottom of the vertical slider 207 is slidably connected to the base 102. The vertical slider 207 can slide left and right on the top of the base 102. At the same time, the slider 208 can only be vertically lifted inside the vertical slider 207. Since the slider 208 is fixedly connected to the cylindrical rod 205, when the V-shaped rod 204 is in Figure 5 In the state shown, the V-shaped rod 204 rotates to the right, which drives the cylindrical rod 205 to move to the right along the track of the guide rail 206, and at the same time the height is lowered. The reciprocating swing of the V-shaped rod 204 can realize the reciprocating change of the left and right positions of the two sliders 208.

[0042] A frame 301 is provided at the rear side of the slider 208. The slider 208 can drive the frame 301 to change its position and always keep it in a horizontal state during the movement. The rear end of the frame 301 is connected to the first mold 302. The first mold 302 is fixedly connected to the frame 301. Two electric push rods 303 are provided on the outer side of the first mold 302. The two electric push rods 303 are arranged symmetrically with the center line of the first mold 302 as the symmetry axis. The front end of the electric push rod 303 is connected to the second mold 304. The telescopic end is fixedly connected to the first mold 302, and the fixed end of the electric push rod 303 is fixedly connected to the second mold 304. The first mold 302 and the second mold 304 cooperate with each other. When the electric push rod 303 contracts, it can drive the second mold 304 and the first mold 302 to cooperate closely to ensure airtightness. When the first mold 302 and the second mold 304 are cooled, the electric push rod 303 actively extends, which can drive the second mold 304 to move forward, so that the first mold 302 and the second mold 304 are away from each other for unloading.

[0043] When the V-shaped rod 204 rotates to the left, it can drive the vertical slide bar 207 to move to the left. A rectangular rod 401 is provided on the inner side of the vertical slide bar 207. The vertical slide bar 207 drives the rectangular rod 401 to move to the left. A bent rod 402 is provided on the rear side of the rectangular rod 401. The rear side of the bent rod 402 is connected to the moving plate 403. The bent rod 402 drives the moving plate 403 to move to the left. A first gear 405 is provided inside the moving plate 403. The bottom of the first gear 405 is meshed with a first rack 404. The bottom of the first rack 404 is connected to the base 102. Then, since the position of the first rack 404 is fixed, when the movable plate 403 moves to the left, the first gear 405 inside it will rotate, and the top of the first gear 405 is meshed with the second rack 406, and the top of the second rack 406 is connected to the box body 501, that is, when the movable plate 403 moves, the first gear 405 rotates to drive the second rack 406 to move to the left, that is, the moving distance of the second rack 406 is greater than the moving distance of the movable plate 403, ensuring that the box body 501 can move to the leftmost position.

[0044] The control assembly includes a second gear 503, which is connected to the bottom of the inclined plate 502. The bottom of the second gear 503 is meshed with a third rack 505, and the third rack 505 is slidably connected to the box body 501. When the third rack 505 moves left and right, it can drive the meshed second gear 503 to rotate. When the second gear 503 rotates, it can drive the inclined plate 502 to rotate. Two baffles 506 are arranged on the outside of the third rack 505. The two baffles 506 are arranged symmetrically with the center line of the base 102 as the symmetry axis. The baffles 506 The rear end is fixedly connected to the vertical plate 107, and the positions of the two baffles 506 are fixed. When the box body 501 moves to the leftmost end or the rightmost end, the third rack 505 will be pushed by the baffle 506, so that the third rack 505 moves left and right in the box body 501, driving the inclined plate 502 to tilt. A coil spring 504 is provided on the rear side of the second gear 503, and the other end of the coil spring 504 is fixedly connected to the box body 501. When the baffle 506 no longer applies force to the third rack 505, the inclined plate 502 can be driven to return to a horizontal state under the action of the coil spring 504.

[0045] A rectangular tube 601 is provided on the top of the box body 501, and the rectangular tube 601 is fixedly connected to the box body 501. A third spring 603 is provided inside the rectangular tube 601, and two piston plates 604 are provided at the outer end of the third spring 603. The two piston plates 604 are arranged symmetrically with the center line of the rectangular tube 601 as the symmetry axis. A cross bar 605 is provided on the outer side of the piston plate 604, and the outer side of the cross bar 605 cooperates with the baffle 506. When the cross bar 605 is not stressed, the two piston plates 604 can be pushed at the outermost side of the rectangular tube 601 under the action of the third spring 603. When the right cross bar 605 is stressed, it will pass through the piston plate 60 4 squeezes the space inside the rectangular cylinder 601, a first solenoid valve 602 is provided at the front end of the rectangular cylinder 601, a bifurcated pipe 606 is provided at the rear side of the rectangular cylinder 601, and high-pressure gas can enter the bifurcated pipe 606. A second solenoid valve 607 is provided at the bottom of the hose 608, and the bottom of the second solenoid valve 607 is connected to the top of the bifurcated pipe 606. The ventilation of the hose 608 is switched by controlling the corresponding second solenoid valve 607 separately. When the rectangular cylinder 601 has high pressure inside, the rectangular cylinder 601 can also be connected to the outside by opening the first solenoid valve 602, so as to achieve the balance of the pressure inside the rectangular cylinder 601.

[0046] When using: Figure 3 In the state shown, the injection tube 106 performs the injection operation to inject material into the first mold 302 and the second mold 304 at the upper end. When the injection is completed, the V-shaped rod 204 is controlled to rotate to the right, and the rear end of the first mold 302 will move to the right close to the front side of the vertical plate 107, and the residual material at the injection port of the rear end of the first mold 302 is cut and smoothed to prevent the residual material from sticking. When the first mold 302 and the second mold 304 move to the lower right corner, the electric push rod 303 actively extends to realize the first mold 302 and the second mold 304 moving away from each other. When the second mold 304 drives When the connecting plate 306 gradually approaches the frame 301, the connecting plate 306 will be gradually squeezed toward the rear through the frame 301, and the material inside the second mold 304 will be pushed through the four guide rods 305 to complete the material ejection. The material after cooling and shaping will fall downwards, and at the same time, the first mold 302 and the second mold 304 on the left side will move to the top to continue the injection operation. Through the cooperation of the V-shaped rod 204 and the moving component, the intermittent injection and unloading of the two groups of the first mold 302 and the second mold 304 are realized, which improves the injection efficiency of the device and reduces the influence of cooling and shaping on the processing efficiency.

[0047] During the rotation of the V-shaped rod 204 to the right, the moving plate 403 can be driven to move to the right. During the movement, the box body 501 can be driven by the control component. While the moving plate 403 moves to the right, the top of the moving plate 403 further moves to the right, so that the box body 501 moves to the rightmost state. At the same time, under the action of the baffle 506, the third rack 505 and the second gear 503 can gradually change the inclined plate 502 into an inclined state. While the inclined plate 502 is tilted and rotated, the electric push rod 303 actively extends and cooperates with the four guide rods 305 to complete the pushing of the material. The gradually inclined inclined plate 502 generates a pushing force on the outside of the material box. At the same time, under the inclined slope of the inclined plate 502, under the action of gravity, the shaped material can be discharged smoothly and quickly.

[0048] During the rotation of the V-shaped rod 204, it is assumed that the V-shaped rod 204 is Figure 2 , rotates to the right, pushing the movable plate 403 to move to the right. When the V-shaped rod 204 rotates 30 degrees, the two first molds 302 are no longer in contact with the front side wall of the vertical plate 107, and the right side cross bar 605 begins to contact the right baffle 506, pushing the right piston plate 604 to move inward. At this time, the second solenoid valve 607 on the right is closed first, and the gas inside the rectangular cylinder 601 begins to enter the left guide rod 305. Under the action of air pressure, the cylindrical plate 309 inside the guide rod 305 extends out, and the gas enters the first mold 302 and the second mold 304. The gas is blown out from the injection port on the rear side of the first mold 302 to clean the impurities inside the first mold 302 and the second mold 304 and the injection port.

[0049] As the V-shaped rod 204 continues to rotate, the first mold 302 and the second mold 304 on the left begin to contact the front side wall of the vertical plate 107. At this time, the rear injection port of the first mold 302 is blocked, and as the movable plate 403 moves, the baffle 506 continues to squeeze the cross bar 605, and the gas in the rectangular tube 601 gradually enters the first mold 302 and the second mold 304. At this time, the gas inside the first mold 302 and the second mold 304 gradually increases. If the air pressure sensor recognizes that the air pressure is gradually increasing during this process, it indicates that there is no gap between the first mold 302 and the second mold 304 at this time, and the internal gas has not flowed out. If it is recognized that the air pressure is not continuously increasing, it indicates that a gap is generated between the first mold 302 and the second mold 304, which will cause flash during the injection molding process. At this time, the first mold 302 and the second mold 304 should be replaced and repaired.

[0050] As the V-shaped rod 204 continues to rotate, the second solenoid valve 607 on the left is closed, and the second solenoid valve 607 on the right is opened. The gas inside the rectangular cylinder 601 begins to enter the right guide rod 305, forming a high pressure inside the guide rod 305. As the electric push rod 303 extends, the guide rod 305 will extend inside the second mold 304. At the same time, under the action of air pressure, the cylindrical plate 309 will be further pushed outward, pushing the material for a second time and increasing the distance of pushing the material, ensuring that the molded parts can be demolded at one time, and cooperating with the inclined plate 502 to complete the rapid unloading of parts.

[0051] It should be noted that, through the cooperation between the V-shaped rod 204 and the moving assembly, when the V-shaped rod 204 rotates to the right, the inclined plate 502 gradually becomes inclined, the electric push rod 303 actively extends, and cooperates with the four guide rods 305 to complete the pushing of the material, and cooperates with the gradually inclined inclined plate 502 to generate a pushing force on the outside of the material box. At the same time, under the inclined slope of the inclined plate 502, under the action of gravity, the shaped material is smoothly and quickly discharged, and the intermittent injection and discharge of the two sets of first molds 302 and the second mold 304 are realized, which improves the material quality. The injection molding efficiency of the device is improved, and the influence of cooling and shaping on the processing efficiency is reduced. In the initial stage of the rotation of the V-shaped rod 204, the two first molds 302 do not contact each other with the front side wall of the vertical plate 107, and the right side cross bar 605 begins to contact the right side baffle 506. The second electromagnetic valve 607 on the right side is closed first, and the gas inside the rectangular cylinder 601 begins to enter the first mold 302 and the second mold 304. The gas is blown out from the injection port on the rear side of the first mold 302, and the impurities inside the first mold 302 and the second mold 304 and the injection port are removed. In the middle of the rotation of the V-shaped rod 204, the first mold 302 on the left side begins to contact the front side wall of the vertical plate 107, and the rear injection port of the first mold 302 is blocked. The gas in the rectangular cylinder 601 continues to enter the first mold 302 and the second mold 304. During this process, the air pressure sensor identifies the internal air pressure. If it is identified that the air pressure is not continuously increased, it indicates that a gap has occurred between the first mold 302 and the second mold 304. The first mold 302 and the second mold 304 should be replaced and repaired. At the end of the rotation of the V-shaped rod 204, the second solenoid valve 607 on the left is closed, and the second solenoid valve 607 on the right is opened, and the gas inside the rectangular cylinder 601 begins to enter the right guide rod 305. As the electric push rod 303 extends, the guide rod 305 will extend inside the second mold 304. At the same time, under the action of air pressure, the cylindrical plate 309 is further pushed outward to push the material for the second time, and the distance for pushing the material is increased, ensuring that the molded parts can be demolded at one time, and the inclined plate 502 is cooperated to complete the rapid unloading of parts.
