Description

Technical Field

[0001] The invention relates to the technical field of injection molding equipment, in particular to an injection molding device for an air outlet assembly of an air conditioner. Background Art

[0002] The air outlet assembly of the air conditioner is an indispensable and important part of the air conditioning system. It is mainly responsible for delivering the treated air evenly and efficiently into the indoor space to achieve the purpose of regulating the indoor temperature, humidity and air quality. As the key node for indoor and outdoor air exchange, the quality and performance of the air outlet assembly of the air conditioner directly affect the efficiency of the entire air conditioning system and the user's comfortable experience. The injection molding device of the air outlet assembly of the air conditioner is a modern injection molding equipment specially used for the production of air outlet assemblies of the air conditioner. The device heats and melts the plastic raw materials to an ideal flow state through a highly precise injection molding process, and then quickly injects them into a pre-designed mold at high pressure. The injection molding machine is the core equipment of the device. Its function is not limited to heating and melting the plastic raw materials, but also responsible for quickly injecting the molten plastic material into the mold under high pressure. During the injection molding process, the plastic raw materials are first heated to a molten state through the barrel, and then pushed by a screw or a piston and injected into the mold cavity of the mold at high pressure. After the injection is completed, the mold remains closed, and the plastic material gradually cools and solidifies in the mold. When the plastic product in the mold is completely solidified, the mold is opened, and the automatic removal device removes the molded air outlet assembly from the mold.

[0003] After the existing injection molding machines have completed the production of products, most of them are shut down and special equipment is used to clean the residual plastic in the injection molding machine. This method is not only time-consuming and labor-intensive, but also greatly reduces production efficiency. In addition, such operation may cause the plastic that has cooled and solidified after the shutdown to adhere tightly to the surfaces of various components inside the equipment and the inner walls of the pipes, making it difficult to completely remove it. When the machine is started again for production, these residual plastics may be mixed into new plastic raw materials, resulting in quality problems such as impurities and uneven performance in the products. Moreover, when these solidified plastics are forcibly removed, it is easy to cause mechanical damage such as scratches and wear to the precision parts of the equipment, thereby increasing the failure rate of the equipment, shortening the maintenance cycle of the equipment, further affecting the normal production progress and increasing the equipment maintenance cost. Summary of the invention

When the machine is started again for production, these residual plastics may be mixed into new plastic raw materials, resulting in quality problems such as impurities and uneven performance in the product.

The push plate 34 is composed of two groups of plug plates that penetrate the fixed frame 31 and are slidably inserted with the fixed frame 31 and a group of pressing plates that squeeze the gas collecting piece 32, so that the collected gas is pushed into the injection device in the injection molding machine 1 to blow out the residual plastic melt therein, and the pressing plate in the push plate 34 is smaller than the mouth-shaped fixed frame 31, so that the pressing plate in the push plate 34 can enter the fixed frame 31. One end of the plug plate in the push plate 34 passes through the fixed frame 31 and is fixedly connected with a linkage rod 35. The linkage rod 35 is Z-shaped. The length of the push plate 34 is greater than the width of the gas collecting member 32. One end of the linkage rod 35 is fixedly connected to the opening and closing device in the injection molding machine 1, so that the linkage rod 35 moves with the opening and closing of the mold. The gas collecting member 32 includes an outer air bag 321 fixedly connected to the inside of the fixing frame 31. The outer air bag 321 is a cube, and its width is greater than that of the fixing frame 31. An inner air bag 322 is arranged inside the outer air bag 321. An exhaust hole 323 is opened at the bottom of the outer air bag 321. A connecting pipe 324 is connected to the bottom of the inner air bag 322. One end of the connecting pipe 324 passes through the outer air bag 321 and is connected to the injection molding machine 1, so that the gas can be discharged into the injection device in the injection molding machine 1. An air outlet hole 1 331 and an air outlet hole 2 332 are provided at the side end of the air inlet pipe 33. There are four groups of air outlet holes 1 331 and air outlet holes 2 332, which are evenly distributed on the outside of the air inlet pipe 33. The air outlet hole 1 331 is provided between the inner air bag 322 and the outer air bag 321, and the air outlet hole 2 332 is provided in the inner air bag 322. A switching cylinder 333 is slidably inserted in the air inlet pipe 33. An air outlet hole 334 is provided at the side end of the switching cylinder 333. There are four groups of air outlet holes 334, which are evenly distributed on the outside of the switching cylinder 333. The bottom end of the switching cylinder 333 is a conical surface. The bottom end of the inside of the air inlet pipe 33 abuts against the conical surface of the bottom end of the switching cylinder 333 to prevent the switching cylinder 333 from falling off from the air inlet pipe 33. Among them, in the initial state, the switching cylinder 333 in the air intake pipe 33 is at the lower limit position of the air intake pipe 33 due to gravity, so that the air outlet hole 1 331 is blocked by the switching cylinder 333, and the air outlet hole 2 332 is connected with the air outlet hole 334. When the gas enters the air intake pipe 33, it enters the inner air bag 322 through the air outlet hole 2 332 and the air outlet hole 334. As the gas in the inner air bag 322 increases, the switching cylinder 333 is pushed to move upward, so that the air outlet hole 2 332 is blocked by the switching cylinder 333, and the air outlet hole 1 331 is connected with the air outlet hole 334, so that the gas enters between the inner air bag 322 and the outer air bag 321 and is discharged from the exhaust hole 323, so that the gas flows between the inner air bag 322 and the outer air bag 321, reducing the temperature loss of the gas in the inner air bag 322.

[0019] For this purpose, in the present technical solution, the injection molding machine 1 adopts the existing technology and is a device specially used for producing plastic products. It usually includes structures such as an opening and closing device, an injection device, and a heating system. When in use, the heating system heats and melts the plastic raw material, and injects it into the mold through the injection device to form the desired product shape. Finally, the cooled and molded product is taken out through the opening and closing device.

[0020] Reference Figure 3 to Figure 4 The collecting member 2 includes a connecting plate 21 fixedly connected to the top of the barrel in the injection molding machine 1. The connecting plate 21 is U-shaped. The top of the barrel in the injection molding machine 1 is connected to the bottom of the connecting plate 21. A collecting bucket 22 is slidably connected inside the connecting plate 21. The bottom diameter of the collecting bucket 22 is larger than the top diameter of the barrel in the injection molding machine 1. The top of the collecting bucket 22 is connected to an air supply pipe 1 23. An air supply pipe 24 is slidably inserted on the outside of the air supply pipe 1 23. One end of the air supply pipe 24 is connected to a filter box 25. The filter box 25 is U-shaped, and the filter box 25 is usually penetrated inside. One end of the filter box 25 is connected to an air supply pipe 3 26. One end of the air supply pipe three 26 is connected with an air pump 27, the output end of the air pump 27 is connected with the air inlet pipe 33, and the air pump 27 is fixedly connected to the fixed frame 31. When collecting waste gas, the collecting hopper 22 and the barrel are staggered to put the plastic raw material, and then the collecting hopper 22 is moved back to the top of the barrel, and the air pump 27 is started. The waste gas enters between the two sets of discharge plates 44 in the filter box 25 from the collecting hopper 22 through the air supply pipe one 23 and the air supply pipe two 24, and contacts with the filter material through the air holes on the discharge plates 44 to remove harmful substances, and then enters the air supply pipe three 26 through the air holes on the guide plate 46, and is finally transported to the air inlet pipe 33 by the air pump 27.

[0021] The above scheme is adopted: the waste gas generated by the barrel during the injection molding process can be effectively collected through the collecting part 2, and the collecting bucket 22 can flexibly adjust its position to facilitate the switching operation of raw material feeding and waste gas collection, and it cooperates with subsequent gas pipes, filter boxes 25 and other components to form a complete waste gas collection and preliminary purification channel, laying the foundation for subsequent further treatment of waste gas, ensuring the continuity and effectiveness of waste gas treatment in the injection molding production environment, helping to reduce the adverse effects of waste gas on the environment and operators, and at the same time also conducive to improving the environmental protection performance and production stability of the entire injection molding device.

[0022] Reference Figures 7 and 8 The discharge device 4 includes a closing plate 41 that is slidably plugged into the side end of the filter box 25. The closing plate 41 is L-shaped and passes through the filter box 25. Two groups of closing plates 41 are provided, which are symmetrically distributed on both sides of the filter box 25. The length of the closing plate 41 is greater than the width of the filter box 25. A receiving groove 42 is opened on the inner side of each group of closing plates 41. A pull rope 43 is fixedly connected in the receiving groove 42. One end of the pull rope 43 is fixedly connected to a discharge plate 44. A spring 45 is provided between the two groups of discharge plates 44. The two ends of the spring 45 are respectively connected to A set of discharge plates 44 are fixedly connected, the pull rope 43 is an elastic rope, the static length of the pull rope 43, that is, the length without deformation, is less than half the length of the filter box 25, and the elastic force of the spring 1 45 is greater than the elastic force of the pull rope 43, the discharge plate 44 is slidably connected to the filter box 25, and the bottom end of the filter box 25 is fixedly connected with a guide plate 46, the guide plate 46 is V-shaped, and the air delivery pipe 3 26 is arranged below the guide plate 46. An inner plate 47 is slidably inserted in the discharge plate 44, and the bottom end of the inner plate 47 abuts against the top end of the guide plate 46, and the discharge plate 44 and the guide plate There are multiple groups of air holes on the V-shaped guide plate 46, and the top part of the V-shaped guide plate 46 does not have air holes, so that the gas passes through the air pipe 24 into the space between the two groups of discharge plates 44, and then passes through the air holes on the discharge plate 44 to contact the filter material between the discharge plate 44 and the closing plate 41, and the adsorption performance of the filter material is used to remove harmful substances in the gas, and then the gas passes through the air holes on the guide plate 46 into the air pipe 3 26. When the opening and closing device in the injection molding machine 1 drives the linkage rod 35 to move, the linkage rod 35 pushes The movable closing plate 41 slides on the side end of the filter box 25, and the movement of the closing plate 41 drives the pull rope 43, and the pull rope 43 pulls the discharge plate 44 to move toward the closing plate 41. Because the elastic force of the spring 1 45 is greater than the elastic force of the pull rope 43, when the pull rope 43 reaches the limit length of elastic deformation, the spring 1 45 stretches, so that the filter material between the discharge plate 44 and the closing plate 41 is pushed out of the filter box 25 and falls into the collection bucket. When the linkage rod 35 is reset, the spring 1 45 returns to its original length, driving the discharge plate 44 to reset, and the closing plate 41 is reset to make the filter box 25 airtight.

[0023] The above scheme is adopted: the automatic discharge of the filter material is realized through the discharge device 4. The automatic discharge function ensures that the used filter material can be cleaned in time, and avoids the filter material from being saturated and failing and still affecting the exhaust gas treatment effect in the device, thereby ensuring the continuous high efficiency of exhaust gas purification, reducing manual intervention, improving the degree of automation and stability of the entire injection molding device, reducing the risk of equipment failure caused by untimely replacement of filter materials or improper operation, and helping to improve production efficiency and product quality.

[0024] Reference Figures 9 and 10 The feeding device 5 includes a support rod 51 fixedly connected to the filter box 25, one end of the support rod 51 is fixedly connected to a storage hopper 52, and the bottom end of the storage hopper 52 is provided with a discharge hole 53, and the discharge hole 53 is arranged in two groups, symmetrically arranged at the bottom end of the storage hopper 52, and a baffle 54 is slidably inserted in each group of discharge holes 53, and one end of the baffle 54 passes through the storage hopper 52, and the baffle 54 is L-shaped. The feeding device 5 also includes a top plate 55 fixedly connected to the top of the filter box 25, and the top plate 55 is provided with two groups, The top of the filter box 25 is symmetrically distributed and fits with the inner wall of the filter box 25. A feeding hole 56 is opened through each group of top plates 55. A storage box 57 is slidably connected to the top of the filter box 25. Two groups of storage boxes 57 are provided, which are symmetrically distributed on the top of the top plate 55. The bottom of the storage box 57 is abutted against the top of the top plate 55. A triangular block is provided at the bottom of the storage box 57. A discharge trough 58 is provided at the bottom of the storage box 57. The discharge trough 58 is provided at the lowest point side end of the triangular block at the bottom of the storage box 57. The side end of the filter box 25 is fixedly connected with a synchronization frame 59, which is U-shaped and slidably connected to the filter box 25. A magnet is embedded in the inner side of the synchronization frame 59, and a magnet is also embedded in the side end of the discharge plate 44. The magnets on the synchronization frame 59 and the corresponding surfaces of the magnets on the discharge plate 44 are of different poles. When the discharge plate 44 moves toward the closing plate 41 under the movement of the linkage rod 35, due to its magnetic adsorption with the synchronization frame 59, the discharge plate 44 drives the synchronization frame 59 and the storage box 57 to move until the storage box 57 is aligned with the stopper. The plate 54 abuts against and pushes the baffle plate 54 to be drawn out from the discharge hole 53. At this time, the filter material in the storage hopper 52 enters the storage box 57 through the discharge hole 53. When the closing plate 41 is reset to make the filter box 25 form a sealed container, the bottom end of the storage box 57 blocks the discharge groove 58 and overlaps with the feed hole 56 on the top plate 55. The opening and closing device of the injection molding machine 1 pauses the reset of the linkage rod 35 to maintain the overlapped state, so that the filter material in the storage box 57 can be filled into the filter box 25, and then the reset operation is continued to restore the components to their original positions.

[0025] The above scheme is adopted: the automatic replenishment of the filter material is realized through the feeding device 5, and new filter material can be prepared for the next round of filtration in time during the discharge process without frequent manual intervention, which greatly improves the automation degree and operation efficiency of the injection molding device, effectively avoids the influence of insufficient or excessive replenishment of the filter material on the exhaust gas treatment effect, ensures the continuous and effective operation of the exhaust gas purification link in the whole injection molding production process, and helps to improve the overall quality and environmental protection performance of product production.

[0026] The working principle of the present invention is: when in use, first push the collecting bucket 22 to make the collecting bucket 22 slide on the connecting plate 21, stagger the collecting bucket 22 with the barrel in the injection molding machine 1, put the plastic raw material into the barrel in the injection molding machine 1, and then move the collecting bucket 22 to the top of the barrel in the injection molding machine 1, and start the air pump 27, so that the waste gas generated by the melting of the plastic passes through the collecting bucket 22, the air pipe 1 23 and the air pipe 2 24 into the two sets of discharge plates 44 in the filter box 25, and then passes through the air holes on the discharge plate 44 to contact with the filter material between the discharge plate 44 and the closing plate 41, and the adsorption performance of the filter material is used to remove harmful substances in the gas, and then the gas passes through the air holes on the guide plate 46 into the air pipe 3 26, and then passes through the air pump 27. The pump 27 enters the air inlet pipe 33. When the gas enters the air inlet pipe 33, it enters the inner air bag 322 through the second air outlet hole 332 and the third air outlet hole 334. As the gas in the inner air bag 322 increases, the switching cylinder 333 is pushed upward, so that the second air outlet hole 332 is blocked by the switching cylinder 333, and the air outlet hole 1 331 is connected with the air outlet hole 334, so that the gas enters between the inner air bag 322 and the outer air bag 321 and is discharged from the exhaust hole 323. When the product is produced, the opening and closing device in the injection molding machine 1 opens the mold to take the product away. At this time, the linkage rod 35 moves with it and drives the push plate 34 to move, so that the inner side of the push plate 34 fits the surface of the outer air bag 321. Then the opening and closing device in the injection molding machine 1 drives the linkage rod 35 to continue moving, so that the push plate 34 is in contact with the surface of the outer air bag 321. The plate 34 squeezes the outer airbag 321 and the inner airbag 322, so that the gas enters the injection device in the injection molding machine 1 through the connecting pipe 324, and blows out the residual plastic melt therein. During the movement of the linkage rod 35, it abuts against the closing plate 41 and pushes the closing plate 41 to move, so that gaps are generated on both sides of the filter box 25. While the closing plate 41 moves, it drives the pull rope 43, so that the pull rope 43 pulls the discharge plate 44 to move toward the closing plate 41 until the pull rope 43 reaches the limit length of elastic deformation, so that the spring 45 is stretched under force, so that the filter material between the discharge plate 44 and the closing plate 41 is pushed out of the filter box 25 and falls into the collection bucket at the side end of the fixing frame 31. During the movement, the closing plate 41 abuts against the filter box 25, so that the pull rope 43 is The material storage box 57 is pushed into the receiving groove 42. During the movement of the discharge plate 44, the synchronous frame 59 magnetically attracted thereto is driven to move synchronously, thereby driving the storage box 57 to move until the storage box 57 abuts against the baffle 54 and pushes the baffle 54 to be drawn out from the discharge hole 53. At this time, the filter material in the storage hopper 52 enters the storage box 57 through the discharge hole 53. When the gas in the inner airbag 322 completely blows out the residual plastic melt in the injection device of the injection molding machine 1, the opening and closing device in the injection molding machine 1 drives the linkage rod 35 to reset. During the reset process, the spring 45 is no longer stressed and restores its original length, and drives the discharge plate 44 to reset. When the closing plate 41 is reset to, one end of the closing plate 41 is in contact with the inner wall of the filter box 25, so that the filter box 25 forms a sealed container.The bottom end of the storage box 57 blocks the discharge groove 58 and overlaps with the feed hole 56 on the top plate 55, so that the filter material in the storage box 57 is filled into the filter box 25. At this time, the opening and closing device in the injection molding machine 1 suspends the reset of the linkage rod 35, so that the overlap state of the discharge groove 58 and the feed hole 56 is maintained until the filter material in the storage box 57 is completely filled into the filter box 25. After that, the opening and closing device in the injection molding machine 1 continues to drive the reset of the linkage rod 35, so that the spring 45 completely restores its original length, and drives the discharge plate 44 to restore to the limit position, so that the discharge groove 58 is misaligned with the feed hole 56, and drives the pull rope 43, so that the pull rope 43 drives the closing plate 41 to penetrate the filter box 25, and the filter box 25 is restored to a closed state; the airbag structure in the cleaning device 3 can effectively preserve and regulate the flow of gas, the inner airbag 322 collects gas first, and as the gas increases, the switching cylinder 333 moves to allow the gas to enter the outer airbag 321, reducing temperature loss, allowing the gas to enter the injection device in a better state to clean up the residual plastic melt and improve product quality. The push plate 34 is linked with the opening and closing device of the injection molding machine 1 by means of the linkage rod 35 to achieve automatic operation, without manual intervention in gas pushing and melt cleaning, ensuring production continuity, reducing the risk of product defects caused by human errors, and improving production efficiency and stability. At the same time, the collection barrel is conducive to waste treatment and process optimization analysis. Through the discharge device 4 can accurately and timely discharge the used filter material in the filter box 25. Through the cooperation of the closing plate 41, the pull rope 43, the discharge plate 44 and the spring 45, when the opening and closing device of the injection molding machine 1 drives the linkage rod 35 to move, each component can be triggered in turn to push the filter material out and drop it into the collection bucket, which effectively prevents the saturation failure of the filter material from affecting the exhaust gas treatment, always ensures efficient and stable purification, protects the health of personnel and the environment, and is linked with the injection molding machine 1 to reduce manual intervention, improve the overall automation level and reliability, reduce the probability of equipment failure caused by the replacement of filter materials, ensure production continuity, and help improve production efficiency and product quality consistency. In addition, its structural design Smart, long-term stable performance, reduce maintenance frequency and cost, realize automatic replenishment of filter materials through the feeding device 5, during the discharge process, the discharge plate 44 moves and drives the synchronous frame 59 and the storage box 57 to move through magnetic adsorption, so that the filter material in the storage hopper 52 enters the storage box 57, and when the closing plate 41 is reset, the storage box 57 and the top plate 55 cooperate to fill the material into the filter box 25, without frequent manual operation, greatly improving the automation degree and operation efficiency of the injection molding device, it can accurately control the amount of filter material replenishment, avoid insufficient or excessive problems, ensure continuous and effective exhaust gas purification, provide a good environment for product production, and improve the environmental protection performance and compliance of the injection molding device.
