Description

Technical Field

[0001] The present invention relates to the technical field of engine parts processing equipment, and specifically relates to an injection molding and demolding mechanism for processing automobile engine parts. Background Technique

[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. Its working principle is similar to that of a syringe used for injection. It injects the pre-plasticized molten plastic into the closed mold cavity and obtains plastic products after curing and shaping.

[0003] Among them, the shells of some injection-molded products are relatively thin. Most equipment uses a push rod to complete the discharging. However, due to the relatively small contact area between the push rod and the finished plastic, when the plastic is not easily separated, the thrust of the push rod is likely to cause deformation of the plastic shell or even penetrate the plastic shell and cause damage. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an injection molding and demolding mechanism for processing automobile engine parts, including a pneumatic box. A limiting bracket is fixedly connected to the side wall of the pneumatic box. One end of the limiting bracket away from the pneumatic box is fixedly connected to a fixed mold.

A fixed ring is fixedly connected to the side wall of the movable mold. Five exhaust square openings are provided on the side wall of the movable mold. Sliding grooves are provided on the inner walls of the five exhaust square openings. Sealing rings are fixedly connected to the side walls of the exhaust square openings. A material pushing component is fixedly connected to the side wall of the movable mold;

[0006] The demoulding mechanism comprises an inclined surface block fixedly connected to the inner wall of the exhaust square port, a sliding block is fixedly connected to the inclined surface of the inclined surface block, a blocking block is slidably connected to the inner wall of the sliding block, a ventilation groove is provided on the side wall of the blocking block, a sliding square rod is fixedly connected to the side wall of the blocking block, a fixed long rod is fixedly connected to the inner wall of the inclined surface block, a mounting square plate is fixedly connected to the inner wall of the exhaust square port, a rotating plate is rotatably connected to the inner wall of the through hole of the mounting square plate, a supporting rod is fixedly connected to the side wall of the fixed long rod, and the sliding square rod rotates away from the end of the blocking block A prying plate is connected, and the end of the prying plate away from the sliding square rod is rotatably connected to a push rod, and the end of the push rod away from the prying plate is fixedly connected to the side wall of the rotating plate, and a blocking component is fixedly connected to the inner wall of the inclined block. 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 inclined block. A sliding long rod is slidably connected to the inner wall of the through hole of the limiting bracket. A blocking slide plate is fixedly connected to the side wall of the sliding long rod. Taking advantage of the characteristic that when air flows, a thrust will be generated in all directions, a blocking slide plate and an inclined block are arranged inside the device. When the electric telescopic rod contracts and the high-pressure gas acts on the side wall of the product in the above manner, the blocking slide plate will have two states. One is that the high-pressure gas acts on the side wall of the product. However, since the product adheres to the outer walls of the movable mold and the fixed ring, the high-pressure gas will apply an outward thrust to the product. At this time, the high-pressure gas does not come into contact with the outside world, and thus the high-pressure gas cannot form an outward air flow.

[0009] Preferably, the blocking assembly further includes a compression spring fixedly connected to the side wall of the blocking slide plate. One end of the compression spring away from the blocking slide plate is fixedly connected to the side wall of the limiting bracket. 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 ports, at this time, the high-pressure gas will form an outward air flow, and this air flow is discharged outward through the small gap between the blocking slide plate and the inclined block. The above flow will drive the blocking slide plate to slide along the inner wall of the sliding groove, so that the blocking slide plate blocks the inclined block. Through the above application of the blocking slide plate, when one of the exhaust ports completes the exhaust, the ventilation groove is blocked in time, avoiding that after one of the exhaust ports finishes discharging gas, the remaining gas is discharged outward through the above path, greatly reducing the gas discharge volume and the outward thrust of the other exhaust ports, and affecting the remaining demolding efficiency.

[0010] Preferably, the blocking assembly further includes a pressure plate fixedly connected to the end of the sliding long rod away from the blocking slide plate. 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. A transmission pipe is connected through the side wall of the hydraulic telescopic rod.

[0011] Preferably, the material pushing assembly includes a hydraulic pipe fixedly connected to the side wall of the movable mold. A piston block is slidably connected to the inner wall of the hydraulic pipe. A pushing round rod is fixedly connected to the side wall of the piston block.

[0012] Preferably, the material pushing assembly further includes a pressure-receiving block fixedly connected to the end of the pushing round rod away from the piston block. A contact bracket is fixedly connected to the side wall of the air pressure box. The outer wall of the sliding square rod is slidably connected to the inner wall of the through hole of the fixed long rod. Taking advantage of the characteristic that the above-mentioned blocking slide plate slides along the inner wall of the sliding groove, a blocking assembly is arranged inside the device. When the blocking slide plate slides, it drives the pressure plate to move towards the limiting bracket direction through the sliding long rod. 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-receiving block to slide outward, so that the pressure-receiving block is in a standby working state.

[0013] Preferably, the pushing assembly also includes an air inlet one-way valve connected through the side wall of the air pressure box, a sealing ring is fixedly connected to the side wall of the fixed mold, and the side wall of the blocking slide is slidably connected to the inner wall of the sliding groove. 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) By taking advantage of the characteristic that when air flows, a thrust will be generated on all sides, a blocking slide plate and an inclined plane block are arranged inside the device. After the electric telescopic rod contracts and the high-pressure gas acts on the side wall of the product in the above-mentioned manner, the blocking slide plate will have two states. One is that the high-pressure gas acts on the side wall of the product. However, since the product adheres to the outer walls of the movable mold and the fixed ring, the high-pressure gas will exert an outward thrust on the product. At this time, the high-pressure gas does not come into contact with the outside world, so the high-pressure gas cannot form an outward air flow. The other is that when the high-pressure gas is discharged outward through one of the exhaust ports, at this time, the high-pressure gas will form an outward air flow, and this air flow is discharged outward through the small gap between the blocking slide plate and the inclined plane block. The above-mentioned flow will drive the blocking slide plate to slide along the inner wall of the sliding groove, so that the blocking slide plate blocks the inclined plane block. Through the application of the above-mentioned blocking slide plate, when one of the exhaust ports completes the exhaust, the ventilation groove is blocked in time to avoid all the remaining gas being discharged outward through the above path after one of the exhaust ports completes the air outlet, greatly reducing the air outlet volume and the outward thrust of the other exhaust ports and affecting the remaining demolding efficiency.

[0017] (3) By taking advantage of the characteristic that the above-mentioned blocking slide plate slides along the inner wall of the sliding groove, a blocking component is arranged inside the device. When the blocking slide plate slides, it drives the pressure plate to move towards the limiting bracket through the sliding long rod. 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 pressed block to slide outward, so that the pressed block is in a state of waiting to work. In addition, the design of the rotating plate rotating into the exhaust port reduces the contact area between the product and the device while avoiding the hard contact between the rotating plate and the product when the rotating plate moves outward and unfolds, causing damage to the outer wall of the product during the demolding process.

[0018] (4) By taking advantage of the characteristic that the above-mentioned blocking slide plate blocks the inclined plane block, a pressed block and a contact bracket are arranged inside the device. As the electric telescopic rod contracts, when the movable mold returns along the inner wall of the air pressure box, all five blocking slide plates will block the corresponding inclined plane blocks due to the air flow, resulting in the movable mold forming a whole 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 pressed block will contact the contact bracket, and as the electric telescopic rod contracts, the pressed block drives the piston block to slide along the inner wall of the hydraulic pipe through the pushing 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 extends, forcing a gap to be formed again between the blocking slide plate and the inclined plane block. The compressed air is sprayed outward simultaneously from the five exhaust ports through the above gap and acts on the side of the finished product to avoid the phenomenon of the finished product sticking.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1. Please refer to Figure 1 - Figure 6 , the present invention is an injection molding demolding mechanism for processing automobile engine parts, including a pneumatic box 1.

A sliding groove 23 is opened on the inner wall of the five exhaust square openings 22. A sealing ring 24 is fixedly connected to the side wall of the exhaust square opening 22. A pushing component 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 demolding mechanism 3 further includes a return spring 313 fixedly connected to the side wall of the fixed long rod 37. One end of the return spring 313 away from the fixed long rod 37 is fixedly connected to the side wall of the plug 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 into the exhaust square opening 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 unfolds, causing damage to the outer wall of the product during the demolding process.

[0035] Embodiment 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 Embodiment 1, the plugging assembly 4 includes a limiting bracket 41 fixedly connected to the inner wall of the inclined block 31. A sliding long rod 42 is slidably connected to the inner wall of the through hole of the limiting bracket 41. A plugging slide plate 43 is fixedly connected to the side wall of the sliding long rod 42. By utilizing the characteristic that when air flows, a thrust will be generated in all directions, a plugging slide plate 43 and an inclined block 31 are arranged inside the equipment. After the electric telescopic rod 13 contracts and the high-pressure gas acts on the side wall of the product in the above manner, the plugging slide plate 43 will have two states. One is that the high-pressure gas acts on the side wall of the product, but since the product adheres to the outer walls of the movable mold 21 and the fixed ring 14, the high-pressure gas will apply an outward thrust to the product. However, at this time, the high-pressure gas does not contact the outside world, so the high-pressure gas cannot form an outward air flow.

[0036] The plugging assembly 4 further includes a compression spring 44 fixedly connected to the side wall of the plugging slide plate 43. One end of the compression spring 44 away from the plugging slide plate 43 is fixedly connected to the side wall of the limiting bracket 41. A limiting plate 35 is fixedly connected to the side wall of the plugging block 33. When the high-pressure gas is discharged outward through one of the exhaust square openings 22, at this time, the high-pressure gas will form an outward air flow, and this air flow is discharged outward through the small gap between the plugging slide plate 43 and the inclined block 31. The above flow will drive the plugging slide plate 43 to slide along the inner wall of the sliding groove 23, so that the plugging slide plate 43 plugs the inclined block 31. Through the above application of the plugging slide plate 43, when one of the exhaust square openings 22 completes exhaust, the ventilation groove 34 is blocked in time, avoiding that after one of the exhaust square openings 22 completes air outlet, the remaining gas is discharged outward through the above path, greatly reducing the air outlet volume and outward thrust of the other exhaust square openings 22 and affecting the remaining demolding efficiency.

[0037] The plugging assembly 4 further includes a pressure plate 45 fixedly connected to one end of the sliding long rod 42 away from the plugging slide plate 43. 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. A transmission pipe 47 is connected through the side wall of the hydraulic telescopic rod 46.

[0038] The material pushing component 5 includes 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. A pushing round rod 53 is fixedly connected to the side wall of the piston block 52.

[0039] The material pushing component 5 further includes a pressure-receiving block 54 fixedly connected to one end of the pushing round rod 53 away from the piston block 52. A contact support 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. By using the characteristic that the above-mentioned blocking slide plate 43 slides along the inner wall of the sliding groove 23, a blocking component 4 is arranged inside the device. When the blocking slide plate 43 slides, it drives the pressure plate 45 to move towards the limiting support 41 through the sliding long rod 42. The pressure plate 45 presses 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-receiving block 54 to slide outwards, so that the pressure-receiving block 54 is in a state of waiting for work.

[0040] The material pushing component 5 further includes an air inlet check valve 56 penetrating and 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. The side wall of the blocking slide plate 43 is slidably connected to the inner wall of the sliding groove 23. By using the characteristic that the above-mentioned blocking slide plate 43 blocks the inclined plane block 31, a pressure-receiving block 54 and a contact support 55 are arranged inside the device. As the electric telescopic rod 13 contracts, when the movable mold 21 returns along the inner wall of the air pressure box 1, all five blocking slide plates 43 will block the corresponding inclined plane blocks 31 due to the airflow, resulting in the movable mold 21 forming a whole sealing plate. 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-receiving block 54 will contact the contact support 55, and as the electric telescopic rod 13 contracts, the pressure-receiving block 54 drives the piston block 52 to slide along the inner wall of the hydraulic pipe 51 through the pushing 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 a gap to be formed again between the blocking slide plate 43 and the inclined plane block 31. The compressed air passes through the above gap and is ejected outwards simultaneously from the five exhaust square ports 22 and acts on the side of the finished product to avoid the phenomenon of the finished product 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] Taking advantage of the feature that the above-mentioned blocking slide plate 43 slides along the inner wall of the sliding groove 23, a blocking assembly 4 is provided inside the device. When the blocking slide plate 43 slides, it drives the pressure plate 45 to move towards the limiting bracket 41 through the sliding long rod 42. The pressure plate 45 squeezes the hydraulic telescopic rod 46, causing the liquid inside the hydraulic telescopic rod 46 to be transmitted through the transmission pipe 47 into the hydraulic pipe 51. The increase in the liquid inside the hydraulic pipe 51 forces 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-receiving block 54 to slide outwards, putting the pressure-receiving block 54 in a working state. Additionally, the design of the rotating plate 39 rotating into the exhaust square opening 22 reduces the contact area between the product and the device and avoids hard contact between the rotating plate 39 and the product when the rotating plate 39 moves outwards and unfolds, preventing damage to the outer wall of the product during the demolding process. Taking advantage of the feature that the above-mentioned blocking slide plate 43 blocks the inclined plane block 31, a pressure-receiving block 54 and a contact bracket 55 are provided inside the device. As the electric telescopic rod 13 contracts, when the movable mold 21 resets along the inner wall of the air pressure box 1, all five blocking slide plates 43 will block the corresponding inclined plane blocks 31 due to the airflow, causing the movable mold 21 to form an integral sealing plate. 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-receiving block 54 will contact the contact bracket 55, and as the electric telescopic rod 13 contracts, the pressure-receiving block 54 drives the piston block 52 to slide along the inner wall of the hydraulic pipe 51 through the pushing round rod 53, causing the solution inside the hydraulic pipe 51 to be transmitted through the transmission pipe 47 into the hydraulic telescopic rod 46. The hydraulic telescopic rod 46 extends, forcing a gap to form again between the blocking slide plate 43 and the inclined plane block 31. The compressed air sprays outwards simultaneously from the five exhaust square openings 22 through the above gap and acts on the side of the finished product to prevent the phenomenon of the finished product sticking.
