[0001] The invention relates to the technical field of engine parts processing equipment, in particular to an injection molding demoulding mechanism for automobile engine parts processing. Background Art
[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. Its working principle is similar to that of a syringe for injection. It injects the plasticized molten plastic into a closed mold cavity, and obtains the plastic product after solidification and shaping.
[0003] The shells of some injection molded products are relatively thin, and most equipment uses push rods to complete the discharge. However, the contact area between the push rod and the finished plastic is small. When the plastic is not easy to separate, the thrust of the push rod can easily cause the deformation of the plastic shell, or even penetrate the plastic shell and cause damage. To solve the above problems, the following solutions are proposed. Summary of the invention

The characteristic of high-pressure gas generating thrust to the surroundings is utilized, and an air outlet mechanism and a demoulding mechanism are arranged inside the equipment. Before use, the air pressure box is installed in the required position, and it is ensured that the external raw materials can enter the fixed mold through the feed pipe, and then the power of the electric telescopic rod is turned on, and the electric telescopic rod is extended, forcing the movable mold and the sealing ring Slide outward along the inner wall of the air pressure box, the movable mold drives the fixed ring to contact the fixed mold, and the fixed mold discharges the raw material into the gap between the fixed mold and the fixed ring. After cooling, the electric telescopic rod generates a contraction force, forcing the exhaust square port and the sealing ring to slide along the inner wall of the air pressure box. In this process, the exhaust square port will compress the air inside the air pressure box, so that the air inside the air pressure box changes from normal pressure to high pressure. The high-pressure gas will exert an outward expansion force on the side wall of the blocking block through the exhaust square port, so that the blocking block moves outward along the inner wall of the sliding block. At this time, the ventilation groove and the sliding block are A first air outlet is formed between the blocks, and as the blocking block moves, the blocking block drives one end of the prying plate to tilt outward through the sliding square rod, and the prying plate uses the support rod as a fulcrum, forcing the prying plate to drive the push rod to press down, and the push rod drives the rotating plate to rotate around the connection point as the center, so that the rotating plate and the installation square plate form a second air outlet, and the high-pressure air acts on the side wall of the finished product through the above first outlet and the second outlet, completing the demoulding process of the finished product. Through the application of the above components, hard contact of the components to cause damage to the parts is avoided.
[0007] Preferably, the demolding mechanism also includes a return spring fixedly connected to the side wall of the fixed long rod, the end of the return spring away from the fixed long rod is fixedly connected to the side wall of the blocking block, the outer wall of the sealing ring is slidably connected to the inner wall of the air pressure box, and the design of the rotating plate rotating toward the exhaust square port reduces the contact area between the product and the equipment while avoiding hard contact between the rotating plate and the product when the rotating plate moves outward and expands outward, causing damage to the outer wall of the product during the demolding process.
[0008] Preferably, the blocking assembly includes a limiting bracket fixedly connected to the inner wall of the ramp block, a sliding long rod slidably connected to the inner wall of the through hole of the limiting bracket, and a blocking slide fixedly connected to the side wall of the sliding long rod, utilizing the characteristic that a thrust will be generated on the surroundings when the airflow flows, and a blocking slide and a ramp block are arranged inside the equipment. When the electric telescopic rod is contracted and the high-pressure gas acts on the side wall of the product in the above manner, the blocking slide will be in two states. First, the high-pressure gas acts on the side wall of the product, but because the product sticks to the movable mold and the outer wall of the fixed ring, the high-pressure gas will exert an outward thrust on the product, but at this time the high-pressure gas is not in contact with the outside world, and at this time the high-pressure gas cannot form an outward airflow.
[0009] Preferably, the blocking assembly also includes a compression spring fixedly connected to the side wall of the blocking slide, and one end of the compression spring away from the blocking slide is fixedly connected to the side wall of the limiting bracket, and a limiting plate is fixedly connected to the side wall of the blocking block. When the high-pressure gas is discharged outward through one of the exhaust square ports, the high-pressure gas will form an outward airflow, and the airflow is discharged outward through the small gap between the blocking slide and the inclined block. The above circulation will drive the blocking slide to slide along the inner wall of the sliding groove, so that the blocking slide blocks the inclined block. Through the application of the above-mentioned setting of the blocking slide, when one of the exhaust square ports completes exhaust, the ventilation groove is blocked in time to avoid the remaining gas being discharged outward through the above path after one of the exhaust square ports completes exhaust, which greatly reduces the exhaust volume and outward thrust of other exhaust square ports, affecting the remaining demolding efficiency.
[0010] Preferably, the blocking assembly also includes a pressure plate fixedly connected to one end of the sliding long rod away from the blocking slide, a hydraulic telescopic rod is fixedly connected to the side wall of the pressure plate, the other end of the hydraulic telescopic rod is fixedly connected to the side wall of the limiting bracket, and a transmission pipe is connected through the side wall of the hydraulic telescopic rod.

Utilizing the characteristics of the above blocking slide blocking the inclined surface block, a pressure block and a contact bracket are provided inside the equipment. As the electric telescopic rod contracts, when the movable mold is reset along the inner wall of the air pressure box, the five blocking slides will block the corresponding inclined surface blocks due to the airflow, causing the movable mold to form an integral sealing plate, and as the electric telescopic rod continues to contract, the air inside the air pressure box will form a high-pressure state again. When the movable mold contracts, the pressure block will contact the contact bracket, and as the electric telescopic rod contracts, the pressure block drives the piston block to slide along the inner wall of the hydraulic pipe by pushing the round rod, so that the solution inside the hydraulic pipe is transmitted to the hydraulic telescopic rod through the transmission pipe, and the hydraulic telescopic rod is extended, forcing a gap to be formed again between the blocking slide and the inclined surface block, and the compressed air passes through the above gap and is ejected outward from the five exhaust square ports at the same time, and acts on the side of the finished product to avoid the sticking phenomenon of the finished product.
[0014] The present invention has the following beneficial effects:
[0015] (1) The present invention utilizes the characteristic of high-pressure gas to generate thrust in all directions, and an air outlet mechanism and a demoulding mechanism are arranged inside the equipment. Before use, the air pressure box is installed at the desired position, and it is ensured that the external raw materials can enter the fixed mold through the feed pipe. Then, the power of the electric telescopic rod is turned on, and the electric telescopic rod is extended, forcing the movable mold and the sealing ring to slide outward along the inner wall of the air pressure box. The movable mold drives the fixed ring to contact the fixed mold, and the fixed mold discharges the raw materials into the gap between the fixed mold and the fixed ring. After cooling, the electric telescopic rod generates a contraction force, forcing the exhaust square port and the sealing ring to slide along the inner wall of the air pressure box. In this process, the exhaust square port will compress the air inside the air pressure box, so that the air inside the air pressure box is compressed from normal pressure to high pressure. When it changes to high pressure, the high-pressure gas exerts an outward expansion force on the side wall of the blocking block through the exhaust square port, causing the blocking block to move outward along the inner wall of the sliding block. At this time, a first air outlet is formed between the ventilation groove and the sliding block, and as the blocking block moves, the blocking block drives one end of the prying plate to tilt outward through the sliding square rod, and the prying plate uses the support rod as a fulcrum, forcing the prying plate to drive the push rod to press down, and the push rod drives the rotating plate to rotate around the connection point, so that the rotating plate and the installation square plate form a second air outlet, and the high-pressure air acts on the side wall of the finished product through the above first outlet and second outlet, completing the demoulding process of the finished product. Through the application of the above components, hard contact of the components to cause damage to the parts can be avoided.
[0016] (2) The present invention utilizes the characteristic that when the airflow flows, it will generate a thrust on the surroundings. A blocking slide and a slope block are arranged inside the equipment. When the electric telescopic rod is retracted and the high-pressure gas acts on the side wall of the product in the above manner, the blocking slide will be in two states. First, the high-pressure gas acts on the side wall of the product. However, since the product is adhered to the outer wall of the movable mold and the fixed ring, the high-pressure gas will exert an outward thrust on the product. However, at this time, the high-pressure gas is not in contact with the outside world and cannot form an outward airflow. Second, when the high-pressure gas is discharged outward through one of the exhaust square ports, the high-pressure gas will form an outward airflow, and the airflow is discharged outward through the small gap between the blocking slide and the slope block. The above circulation will drive the blocking slide to slide along the inner wall of the sliding groove, so that the blocking slide blocks the slope block. Through the application of the above-mentioned blocking slide, when one of the exhaust square ports completes exhaust, the ventilation groove is blocked in time to prevent the remaining gas from being discharged outward through the above path after one of the exhaust square ports completes exhaust, greatly reducing the exhaust volume and outward thrust of the other exhaust square ports, affecting the remaining demoulding efficiency.
[0017] (3) The present invention utilizes the characteristic that the blocking slide slides along the inner wall of the sliding groove, and a blocking assembly is arranged inside the equipment. When the blocking slide slides, the pressure plate is driven to move toward the direction of the limited bracket through the sliding long rod, and the pressure plate squeezes the hydraulic telescopic rod, so that the liquid inside the hydraulic telescopic rod is transmitted to the inside of the hydraulic pipe through the transmission pipe. The liquid inside the hydraulic pipe increases, forcing the piston block to slide along the inner wall of the hydraulic pipe. The hydraulic pipe drives the pushing round rod and the pressure block to slide outward, so that the pressure block is in a waiting state. In addition, the design of the rotating plate rotating into the exhaust square port reduces the contact area between the product and the equipment, while avoiding the rotating plate from being in hard contact with the product when it moves outward and expands outward, causing damage to the outer wall of the product during the demolding process.
[0018] (4) The present invention utilizes the characteristics of the above-mentioned blocking slide plate blocking the inclined surface block, and a pressure block and a contact bracket are arranged inside the device. As the electric telescopic rod contracts, when the movable mold is reset along the inner wall of the air pressure box, the five blocking slide plates will block the corresponding inclined surface blocks due to the airflow, causing the movable mold to form an integral sealing plate. As the electric telescopic rod continues to contract, the air inside the air pressure box will form a high-pressure state again. When the movable mold contracts, the pressure block will contact the contact bracket. As the electric telescopic rod contracts, the pressure block drives the piston block to slide along the inner wall of the hydraulic pipe by pushing the round rod, so that the solution inside the hydraulic pipe is transmitted to the hydraulic telescopic rod through the transmission pipe. The hydraulic telescopic rod is extended, forcing a gap to be formed again between the blocking slide plate and the inclined surface block. The compressed air passes through the above gap and is ejected outward from the five exhaust ports at the same time, and acts on the side of the finished product to avoid the sticking phenomenon of the finished product.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A sealing ring 24 is fixedly connected to the side wall of the exhaust square port 22, and a pusher assembly 5 is fixedly connected to the side wall of the movable mold 21;
[0033] The demoulding mechanism 3 includes a bevel block 31 fixedly connected to the inner wall of the exhaust square port 22, a sliding block 32 fixedly connected to the bevel of the bevel block 31, a blocking block 33 slidably connected to the inner wall of the sliding block 32, a ventilation groove 34 is provided on the side wall of the blocking block 33, a sliding square rod 36 is fixedly connected to the side wall of the blocking block 33, a fixed long rod 37 is fixedly connected to the inner wall of the bevel block 31, a mounting square plate 38 is fixedly connected to the inner wall of the exhaust square port 22, a rotating plate 39 is rotatably connected to the inner wall of the through hole of the mounting square plate 38, a support rod 310 is fixedly connected to the side wall of the fixed long rod 37, and the sliding square rod 36 is away from the blocking block One end of 33 is rotatably connected to a prying plate 311, and the end of the prying plate 311 away from the sliding square rod 36 is rotatably connected to a push rod 312, and the end of the push rod 312 away from the prying plate 311 is fixedly connected to the side wall of the rotating plate 39, and the inner wall of the inclined surface block 31 is fixedly connected to a blocking component 4. By utilizing the characteristic of high-pressure gas generating thrust to the surroundings, an air outlet mechanism 2 and a demoulding mechanism 3 are arranged inside the equipment. Before use, the air pressure box 1 is installed in the required position, and it is ensured that the external raw materials can enter the fixed mold 11 through the feed pipe 12, and then the power of the electric telescopic rod 13 is turned on, and the electric telescopic rod 13 is extended, forcing the movable mold 21 The sealing ring 24 slides outward along the inner wall of the air pressure box 1, and the movable mold 21 drives the fixed ring 14 to contact the fixed mold 11. The fixed mold 11 discharges the raw material into the gap between the fixed mold 11 and the fixed ring 14. After cooling, the electric telescopic rod 13 generates a contraction force, forcing the exhaust square port 22 and the sealing ring 24 to slide along the inner wall of the air pressure box 1. In this process, the exhaust square port 22 will compress the air inside the air pressure box 1, so that the air inside the air pressure box 1 changes from normal pressure to high pressure. The high-pressure gas will act on the side wall of the blocking block 33 through the exhaust square port 22 with an outward expansion force, so that the blocking block 33 moves outward along the inner wall of the sliding block 32. At this time, the ventilation groove 3 4 and the sliding block 32 form a first air outlet, and as the blocking block 33 moves, the blocking block 33 drives one end of the prying plate 311 to tilt outward through the sliding square rod 36, and the prying plate 311 uses the support rod 310 as a fulcrum, forcing the prying plate 311 to drive the push rod 312 to press down, and the push rod 312 drives the rotating plate 39 to rotate around the connection point, so that the rotating plate 39 and the installation square plate 38 form a second air outlet, and the high-pressure air acts on the side wall of the finished product through the above first outlet and second outlet, completing the demoulding process of the finished product. Through the application of the above components, hard contact of the components to cause damage to the parts is avoided.
[0034] The demoulding mechanism 3 also includes a return spring 313 fixedly connected to the side wall of the fixed long rod 37. The end of the return spring 313 away from the fixed long rod 37 is fixedly connected to the side wall of the blocking block 33. The outer wall of the sealing ring 24 is slidably connected to the inner wall of the air pressure box 1. The design of the rotating plate 39 rotating toward the exhaust square port 22 reduces the contact area between the product and the equipment while avoiding hard contact between the rotating plate 39 and the product when the rotating plate 39 moves outward and expands outward, causing damage to the outer wall of the product during the demoulding process.
[0035] For example 2, please refer to Figure 7 - Figure 8 The present invention is an injection molding demolding mechanism for processing automobile engine parts. On the basis of the first embodiment, the blocking component 4 includes a limiting bracket 41 fixedly connected to the inner wall of the inclined block 31, and a sliding long rod 42 is slidably connected to the inner wall of the through hole of the limiting bracket 41. A blocking slide 43 is fixedly connected to the side wall of the sliding long rod 42. When the airflow flows, a thrust will be generated on the surroundings. A blocking slide 43 and an inclined block 31 are arranged inside the device. When the electric telescopic rod 13 contracts and the high-pressure gas acts on the side wall of the product in the above manner, the blocking slide 43 will appear in two states. First, the high-pressure gas acts on the side wall of the product, but because the product is adhered to the outer wall of the movable mold 21 and the fixed ring 14, the high-pressure gas will exert an outward thrust on the product, but at this time the high-pressure gas is not in contact with the outside world, and the high-pressure gas cannot form an outward airflow.
[0036] The blocking assembly 4 also includes a compression spring 44 fixedly connected to the side wall of the blocking slide 43, and one end of the compression spring 44 away from the blocking slide 43 is fixedly connected to the side wall of the limiting bracket 41, and a limiting plate 35 is fixedly connected to the side wall of the blocking block 33. When the high-pressure gas is discharged outward through one of the exhaust square ports 22, the high-pressure gas will form an outward airflow at this time, and the airflow will be discharged outward through the small gap between the blocking slide 43 and the inclined block 31. The above circulation will drive the blocking slide 43 to slide along the inner wall of the sliding groove 23, so that the blocking slide 43 blocks the inclined block 31. Through the application of the above-mentioned setting of the blocking slide 43, when one of the exhaust square ports 22 completes exhaust, the ventilation groove 34 is blocked in time to avoid that after one of the exhaust square ports 22 completes exhaust, the remaining gas is discharged outward through the above path, which greatly reduces the exhaust volume and outward thrust of other exhaust square ports 22, affecting the remaining demolding efficiency.
[0037] The blocking assembly 4 also includes a pressure plate 45 fixedly connected to the end of the sliding long rod 42 away from the blocking slide 43, and a hydraulic telescopic rod 46 is fixedly connected to the side wall of the pressure plate 45. The other end of the hydraulic telescopic rod 46 is fixedly connected to the side wall of the limiting bracket 41, and a transmission pipe 47 is connected through the side wall of the hydraulic telescopic rod 46.
[0038] The pusher assembly 5 comprises a hydraulic pipe 51 fixedly connected to the side wall of the movable mold 21 , a piston block 52 is slidably connected to the inner wall of the hydraulic pipe 51 , and a pushing rod 53 is fixedly connected to the side wall of the piston block 52 .
[0039] The pushing assembly 5 also includes a pressure block 54 fixedly connected to the end of the pushing round rod 53 away from the piston block 52. A contact bracket 55 is fixedly connected to the side wall of the air pressure box 1. The outer wall of the sliding square rod 36 is slidably connected to the inner wall of the through hole of the fixed long rod 37. Utilizing the characteristic that the above-mentioned blocking slide 43 slides along the inner wall of the sliding groove 23, a blocking assembly 4 is arranged inside the equipment. When the blocking slide 43 slides, the pressure plate 45 is driven by the sliding long rod 42 to move toward the direction of the limited bracket 41. The pressure plate 45 squeezes the hydraulic telescopic rod 46, so that the liquid inside the hydraulic telescopic rod 46 is transmitted to the inside of the hydraulic pipe 51 through the transmission pipe 47. The liquid inside the hydraulic pipe 51 increases, forcing the piston block 52 to slide along the inner wall of the hydraulic pipe 51. The hydraulic pipe 51 drives the pushing round rod 53 and the pressure block 54 to slide outward, so that the pressure block 54 is in a waiting state.
[0040] The pusher assembly 5 also includes an air inlet non-return valve 56 connected to the side wall of the air pressure box 1, a sealing ring 57 is fixedly connected to the side wall of the fixed mold 11, and the side wall of the blocking slide 43 is slidably connected to the inner wall of the sliding groove 23. By utilizing the characteristics of the blocking slide 43 blocking the inclined block 31, a pressure block 54 and a contact bracket 55 are arranged inside the device. As the electric telescopic rod 13 contracts, when the movable mold 21 is reset along the inner wall of the air pressure box 1, the five blocking slides 43 will block the corresponding inclined blocks 31 due to the airflow, causing the movable mold 21 to form an integral sealing plate, and as the electric telescopic rod 13 continues to contract , the air inside the air pressure box 1 will form a high-pressure state again. When the movable mold 21 shrinks, the pressure block 54 will contact the contact bracket 55, and as the electric telescopic rod 13 shrinks, the pressure block 54 drives the piston block 52 to slide along the inner wall of the hydraulic pipe 51 by pushing the round rod 53, so that the solution inside the hydraulic pipe 51 is transmitted to the hydraulic telescopic rod 46 through the transmission pipe 47. The hydraulic telescopic rod 46 extends, forcing the gap between the blocking slide 43 and the inclined block 31 to be formed again. The compressed air passes through the above gap and is ejected outward from the five exhaust square ports 22 at the same time, and acts on the side of the finished product to prevent the finished product from sticking.
[0041] A specific application of this embodiment is: before use, the air pressure box 1 is installed at the required position, and it is ensured that the external raw materials can enter the fixed mold 11 through the feed pipe 12, and then the power of the electric telescopic rod 13 is turned on, and the electric telescopic rod 13 is extended, forcing the movable mold 21 and the sealing ring 24 to slide outward along the inner wall of the air pressure box 1, and the movable mold 21 drives the fixed ring 14 to contact the fixed mold 11, and the fixed mold 11 discharges the raw materials into the gap between the fixed mold 11 and the fixed ring 14. After cooling, the electric telescopic rod 13 generates a contraction force, forcing the exhaust square port 22 and the sealing ring 24 to slide along the inner wall of the air pressure box 1. In this process, the exhaust square port 22 will compress the air inside the air pressure box 1, so that the air inside the air pressure box 1 changes from normal pressure to high pressure, and the high-pressure gas passes through the exhaust square port 22 applies an outward expansion force to the side wall of the blocking block 33, so that the blocking block 33 moves outward along the inner wall of the sliding block 32. At this time, a first air outlet is formed between the vent groove 34 and the sliding block 32. As the blocking block 33 moves, the blocking block 33 drives one end of the prying plate 311 to tilt outward through the sliding square rod 36, and the prying plate 311 uses the support rod 310 as a fulcrum, forcing the prying plate 311 to drive the push rod 312 to press down, and the push rod 312 drives the rotating plate 39 to rotate around the connection point, so that the rotating plate 39 and the mounting square plate 38 form a second air outlet, and the high-pressure air acts on the side wall of the finished product through the above first outlet and second outlet, completing the demoulding process of the finished product. Through the application of the above components, hard contact of the components to cause damage to the parts is avoided.
[0042] Taking advantage of the fact that when the airflow flows, it will generate a thrust on the surroundings, a blocking slide 43 and a slope block 31 are arranged inside the device. When the electric telescopic rod 13 is contracted, the high-pressure gas acts on the side wall of the product in the above manner, and the blocking slide 43 will appear in two states. First, the high-pressure gas acts on the side wall of the product, but because the product is adhered to the outer wall of the movable mold 21 and the fixed ring 14, the high-pressure gas will exert an outward thrust on the product, but at this time the high-pressure gas is not in contact with the outside world, and the high-pressure gas cannot form an outward airflow at this time; second, when the high-pressure gas is discharged outward through one of the exhaust square ports 22, at this time The high-pressure gas will form an outward airflow, and the airflow will be discharged outward through the small gap between the blocking slide 43 and the inclined block 31. The above circulation will drive the blocking slide 43 to slide along the inner wall of the sliding groove 23, so that the blocking slide 43 blocks the inclined block 31. Through the application of the above-mentioned setting of the blocking slide 43, when one of the exhaust square ports 22 completes the exhaust, the ventilation groove 34 is blocked in time to avoid that after one of the exhaust square ports 22 completes the exhaust, the remaining gas is discharged outward through the above path, which greatly reduces the exhaust volume and outward thrust of other exhaust square ports 22, affecting the remaining demolding efficiency.
[0043] Utilizing the characteristic that the blocking slide plate 43 slides along the inner wall of the sliding groove 23, a blocking assembly 4 is provided inside the equipment. When the blocking slide plate 43 slides, the pressure plate 45 is driven to move toward the direction of the limited bracket 41 through the sliding long rod 42. The pressure plate 45 squeezes the hydraulic telescopic rod 46, so that the liquid inside the hydraulic telescopic rod 46 is transmitted to the inside of the hydraulic pipe 51 through the transmission pipe 47. The liquid inside the hydraulic pipe 51 increases, forcing the piston block 52 to slide along the inner wall of the hydraulic pipe 51. The hydraulic pipe 51 drives the pushing round rod 53 and the pressure block 54 to slide outward, so that the pressure block 54 is in a waiting state. In addition, the design of rotating plate 39 rotating into the exhaust square port 22 reduces the contact area between the product and the equipment while avoiding the rotating plate 39 from being in hard contact with the product when it moves outward and expands outward, causing damage to the outer wall of the product during the demoulding process. Utilizing the characteristic that the blocking slide plate 43 blocks the inclined block 31, a blocking assembly 4 is provided inside the equipment. The pressing block 54 and the contact bracket 55, as the electric telescopic rod 13 contracts, when the movable mold 21 is reset along the inner wall of the air pressure box 1, the five blocking slides 43 will block the corresponding inclined plane blocks 31 due to the airflow, causing the movable mold 21 to form an integral sealing plate, and as the electric telescopic rod 13 continues to contract, the air inside the air pressure box 1 will form a high-pressure state again. When the movable mold 21 contracts, the pressure block 54 will contact the contact bracket 55, and as the electric telescopic rod 13 contracts, the pressure block 54 drives the piston block 52 to slide along the inner wall of the hydraulic pipe 51 by pushing the round rod 53, so that the solution inside the hydraulic pipe 51 is transmitted to the hydraulic telescopic rod 46 through the transmission pipe 47, and the hydraulic telescopic rod 46 is extended, forcing the blocking slide 43 and the inclined plane block 31 to form a gap again. The compressed air passes through the above gap and is ejected outward from the five exhaust square ports 22 at the same time, and acts on the side of the finished product to avoid the sticking phenomenon of the finished product.
