Description

Technical Field

[0001] The present invention relates to the technical field of integrated forming molds for fan blades, and specifically to an integrated forming mold for fan blades and frames. Background Art

[0002] Fan blades have complex shapes, uneven wall thicknesses, high dimensional accuracy requirements, and high surface quality and dimensional stability requirements. Most fan blades are made of plastic and are generally manufactured by injection molding. Injection molding has the following advantages: there are almost no complexity limitations, different thermoplastics can be allowed in the mold; there are no restrictions on the quality of the plastic parts; thermoplastics with suitable fluidity within a certain temperature range; high-precision plastic parts can be injected, with good surface quality and dimensional stability, etc.

[0003] Among them, when the equipment completes cooling and demolding, due to the curved shape of the fan blade and the fact that the fan blade is mostly thin and sheet-shaped, the contact area between the fan blade and the mold is too large, which results in excessive resistance when the fan blade is demolded. For push rod demolding, the center of the finished product is subjected to a thrust force, and there is resistance around the fan blades. Even after demolding is completed, the fan blades will have small deformations due to the existence of resistance. 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 integrated forming mold for fan blades and frames, including a front clamping plate. A upper frame is fixedly connected to the side wall of the front clamping plate. A positioning rod is fixedly connected to the outer wall of the upper frame. A fixed mold one is fixedly connected to the inner wall of the upper frame;

[0005] The mold mechanism, after being combined with the fixed mold one, will form an injection space inside. After the external plastic melt enters the above injection space, it is cooled and formed;

[0006] The material discharging mechanism is fixedly connected to the outer wall of the mold mechanism, used for transporting the plastic melt and discharging the excess melt in the injection space to the outside;

[0007] The adjusting mechanism is fixedly connected to the side wall of the mold mechanism, used for reducing the resistance suffered by the product during demolding;

[0008] Among them, before use, first install the front clamping plate and the mold mechanism on the left and right, and fix them inside the pressure equipment. Subsequently, the front clamping plate and the mold mechanism approach each other, so that an injection space is formed inside the fixed mold one and the mold mechanism. Subsequently, the material discharging mechanism injects the plastic. After cooling, the adjusting mechanism reduces the contact area between the side wall of the injection space and the finished product.

[0009] Preferably, the mold mechanism includes:

[0010] The support assembly, the support assembly is arranged on the side wall of the front clamping plate through a support member;

[0011] The support member includes a rear mold clamping plate, and a pneumatic box is fixedly connected to the side wall of the rear mold clamping plate;

[0012] A driving assembly, the driving assembly is fixedly connected to the side wall of the pneumatic box through a driving member;

[0013] The driving member includes a bottom frame fixedly connected to the side wall of the pneumatic box, and a middle frame is fixedly connected to the side wall of the bottom frame;

[0014] Wherein, after the equipment is cooled, the discharging mechanism will generate high pressure and transmit it to the injection molding space through the pneumatic box and the adjusting mechanism to complete the demolding process of the equipment.

[0015] Preferably, the discharging mechanism includes:

[0016] An exhaust assembly, the exhaust assembly is fixedly connected to the side wall of the middle frame through an air conveying member;

[0017] The air conveying member includes a feeding plate penetrating and connecting to the side wall of the middle frame, and an exhaust block is fixedly connected to the outer wall of the middle frame;

[0018] An inflation assembly, the inflation assembly is fixedly connected to the inner wall of the pneumatic box through an inflation member;

[0019] The inflation member includes a pneumatic machine penetrating and connecting to the inner wall of the pneumatic box;

[0020] Wherein, before using the equipment, first fixedly connect the rear mold clamping plate and the front clamping plate inside the left - right moving pressing device, and ensure that the feeding plate is at the bottom and the exhaust block is at the top. Connect the external air pipe and the material pipe to penetrate through the feeding plate to ensure that the external air pipe and the material pipe can transmit nitrogen and plastic melt to the injection molding space.

[0021] Preferably, the adjusting mechanism includes:

[0022] A control assembly, the control assembly is fixedly connected to the inner wall of the support assembly;

[0023] A closing assembly, the closing assembly is fixedly connected to the inner wall of the pneumatic box through a blocking member;

[0024] The blocking member includes a fixed sliding frame fixedly connected to the inner wall of the pneumatic box, a blocking plate is slidably connected to the inner wall of the fixed sliding frame, and a second spring is fixedly connected to the inner wall of the blocking plate. One end of the second spring away from the blocking plate is fixedly connected to the inner wall of the second spring;

[0025] Wherein, after the gas inside the pneumatic box is transmitted to the inside of the injection molding space through the control assembly, if the gas cannot be effectively discharged to the external environment, at this time the blocking plate will be in an immovable state, and when the gas in the pneumatic box is directly transmitted to the external environment, the blocking plate will cause a blockage to limit the continuous flow of the gas.

[0026] Preferably, the support assembly includes a fixed block fixedly connected to the side wall of the air pressure box, and the outer wall of the fixed block is fixedly connected to the inner wall of the through hole of the bottom frame;

[0027] Among them, the air compressor injects gas into the air pressure box, and the air pressure box injects high-pressure gas into the injection space through the fixed block and the adjustment mechanism to assist the demolding process of the auxiliary equipment;

[0028] The external air pipe replenishes nitrogen into the injection space. Since the mass of nitrogen is greater than that of air, the air in the injection space will be discharged outward through the exhaust block. Subsequently, the plastic melt will enter the injection space through the feeding plate and gradually fill the internal space, and the excess plastic melt will overflow outward through the exhaust block. Then the equipment enters the cooling process to ensure that the equipment is in a static state.

[0029] Preferably, the driving assembly includes a plurality of movable mold cylinders fixedly connected to the side wall of the bottom frame, and the output ends of the plurality of movable mold cylinders are fixedly connected with movable molds;

[0030] Among them, during use, each movable mold cylinder drives the movable molds to gather together, and makes the plurality of movable molds form a circular shape, presenting a state as shown in Figure 4 Then the pressing device drives the front clamping plate and the rear mold clamping plate to approach each other, so that an injection space is formed among the hollow mold, the fixed mold one and the movable mold.

[0031] Preferably, the exhaust assembly includes a hollow mold fixedly connected to the outer wall of the fixed block, and an electric push block is fixedly connected to the side wall of the bottom frame;

[0032] Among them, after the mold is cooled, when the front clamping plate and the rear mold clamping plate are separated, and each movable mold cylinder drives the movable mold away from the side wall of the finished product, the electric push block will extend and push the material outward;

[0033] When the equipment needs to be demolded, each movable mold cylinder will drive the corresponding movable mold away from the side wall of the finished product, reducing the contact area between the movable mold and the finished product. As the pressing device forces the front clamping plate and the rear mold clamping plate to separate, at this time, the outer surface of the fixed mold one and the finished product will be separated. Through the application of the above components, when the equipment is demolded, the contact surface between the finished product and the inner wall of the mold is reduced, and the resistance effect on the fan blade during demolding is reduced.

[0034] Preferably, the inflation assembly includes an exhaust port opened on the inner wall of the air pressure box, and an exhaust through hole is opened on the inner wall of the fixed block;

[0035] Among them, the high-pressure gas blown out by the air pressure box will be transmitted to the injection space through the exhaust port and the exhaust through hole, reducing the contact surface between the finished product and the inner wall of the mold during mold demolding;

[0036] Taking advantage of the characteristic that the high-pressure gas flows outwards from the gap, a blocking plate is provided inside the device. Before use, the blocking plate is pushed by the second spring, and there will be a small gap for air to communicate between the blocking plate and the exhaust through-hole. When the high-pressure gas acts on the side wall of the product but does not circulate with the external environment, at this time, the adhesion position between the finished product and the fan blade, as well as the inner wall of the hollow mold, will be in a sealed state. At this time, the high-pressure gas only generates thrust and no flowing force. After the high-pressure gas completes the detachment of a single fan blade from the outer wall of the hollow mold, at this time, the high-pressure gas will flow outwards from the pressure box through the exhaust through-hole and Figure 9 gap G. The flowing force generated during this process will force the blocking plate to move towards the exhaust through-hole and block the exhaust through-hole. Through the application of the above components, when the high-pressure gas is used for demolding, after a single hollow mold is demolded, the corresponding blocking plate will block the exhaust through-hole, preventing the demolded hollow mold from discharging gas outwards again, and avoiding the pressure drop of the gas demolding of the remaining hollow molds due to gas loss in a single hollow mold, which affects the demolding efficiency of the remaining hollow molds.

[0037] Preferably, the control component includes a first spring fixedly connected to the top of the fixed block. One end of the first spring away from the fixed block is fixedly connected to a fixing plate. The bottom of the fixing plate is fixedly connected to a sliding block. The outer wall of the sliding block is slidably connected to the inner wall of the exhaust through-hole. An exhaust groove is opened at the bottom of the sliding block.

[0038] When the air pressure inside the pressure box increases, at this time, the high-pressure gas will force the sliding block to slide upwards along the inner wall of the exhaust through-hole and enter the inner wall of the hollow mold through the gap between the exhaust groove and the exhaust through-hole.

[0039] After all the hollow molds are demolded by air pressure, at this time, the contact surface between the side wall of the fan blade and the inner wall of the mold will be small. At this time, the power supply of the electric push block is turned on, causing the electric push block to extend, forcing the electric push block to drive the finished product to completely separate from the inner wall of the mold, completing the demolding process of the device. And at this time, the air compressor stops running, the high-pressure gas disappears, the second spring drives the blocking plate to reset, and each first spring drives the fixing plate to reset. The reset fixing plate forces the shielding arc plate to block the air outlet groove again through the inclined rod.

[0040] Preferably, the sealing component includes two air outlet grooves opened on the side wall of the hollow mold. A shielding arc plate is rotatably connected to the inner walls of the two air outlet grooves. An inclined rod is rotatably connected to the side wall of the fixing plate. One end of the inclined rod away from the fixing plate is rotatably connected to the inner wall of the shielding arc plate.

[0041] Among them, when the sliding block drives the fixing plate to move upwards, the inclined rod will drive the shielding arc plate to move a small range towards the fixing plate with the connection point as the center. At this time, the high-pressure gas will directly act on the side wall of the finished product.

[0042] When the front clamping plate and the rear die clamping plate are separated, the air compressor will generate high-pressure gas and transmit it to the inner wall of the air pressure box. At this time, as the pressure increases, the high-pressure gas will push the sliding block along the inner wall of the exhaust through-hole towards the hollow mold, forcing the sliding block to drive the fixed plate to move synchronously. As shown in Figure 9 the figure, the fixed plate drives the shielding arc plate to rotate around the connection point through the inclined rod, causing a small gap to appear between the shielding arc plate and the air outlet groove, presenting the state as shown in Figure 9 G in the figure. Through the application of the above components, the contact area between the shielding arc plate and the finished product is reduced, and the resistance suffered by the finished product during demolding is reduced;

[0043] Due to the characteristic that there is a gap between the above-mentioned shielding arc plate and the air outlet groove, when the high-pressure gas enters the interior of the hollow mold, the high-pressure gas will directly act on the side wall of the finished product through the above gap. Through the push of the high-pressure gas, the finished product adhered to the side wall of the hollow mold will receive an outward thrust, causing the outer wall of the finished product fan blade to move away from the side wall of the hollow mold, greatly reducing the contact area between the finished product fan blade and the inner wall of the mold.

[0044] The present invention has the following beneficial effects:

[0045] (1) When the equipment needs to demold, each movable die oil cylinder will drive the corresponding movable die away from the side wall of the finished product, reducing the contact area between the movable die and the finished product. As the pressing device forces the front clamping plate and the rear die clamping plate to separate, at this time, the fixed die 1 and the outer surface of the finished product will separate. Through the application of the above components, when the equipment demolds, the contact area between the finished product and the inner wall of the mold is reduced, and the resistance influence suffered by the fan blade during demolding is reduced.

[0046] (2) When the front clamping plate and the rear die clamping plate are separated, the air compressor will generate high-pressure gas and transmit it to the inner wall of the air pressure box. At this time, as the pressure increases, the high-pressure gas will push the sliding block along the inner wall of the exhaust through-hole towards the hollow mold, forcing the sliding block to drive the fixed plate to move synchronously. As shown in Figure 9 the figure, the fixed plate drives the shielding arc plate to rotate around the connection point through the inclined rod, causing a small gap to appear between the shielding arc plate and the air outlet groove, presenting the state as shown in Figure 9 G in the figure. Through the application of the above components, the contact area between the shielding arc plate and the finished product is reduced, and the resistance suffered by the finished product during demolding is reduced.

[0047] (3) Utilizing the characteristic that there is a gap between the above-mentioned shielding arc plate and the air outlet groove, when the high-pressure gas enters the interior of the hollow mold, the high-pressure gas will directly act on the side wall of the finished product through the above gap. Through the push of the high-pressure gas, the finished product adhered to the side wall of the hollow mold will receive an outward thrust, causing the outer wall of the finished product fan blade to move away from the side wall of the hollow mold, greatly reducing the contact area between the finished product fan blade and the inner wall of the mold.

[0048] (4) By taking advantage of the characteristic that the high-pressure gas flows outwards from the gap, when the high-pressure gas acts on the side wall of the product but does not circulate with the external environment, only thrust is generated by the high-pressure gas, and there is no flow force; while after the high-pressure gas completes the detachment of a single fan blade from the outer wall of the hollow mold, the flow force generated during this process will force the blocking plate to move towards the exhaust through-hole and block the exhaust through-hole. Through the application of the above components, the hollow mold that has completed demolding cannot discharge gas outwards again, avoiding the pressure drop of gas demolding of the remaining hollow molds due to gas loss in a single hollow mold, which affects the demolding efficiency of the remaining hollow molds.

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.

[0064] Embodiment 1. Please refer to Figure 1 - Figure 6 , the present invention is a one-piece forming mold for a fan blade frame, including a front clamping plate 13. A side wall of the front clamping plate 13 is fixedly connected with an upper frame 14. An outer wall of the upper frame 14 is fixedly connected with a positioning rod 16. An inner wall of the upper frame 14 is fixedly connected with a fixed mold one 15;

[0065] The mold mechanism 1, after being combined with the fixed mold one 15, an injection space will be formed inside. After the external plastic melt enters the above injection space, it will be cooled and formed;

[0066] The discharging mechanism 2 is fixedly connected to an outer wall of the mold mechanism 1, and is used for transporting the plastic melt and discharging the excess melt in the injection space to the outside;

[0067] The adjusting mechanism 3 is fixedly connected to a side wall of the mold mechanism 1, and is used for reducing the resistance when the product is demolded;

[0068] Among them, before use, first position the front clamping plate 13 and the mold mechanism 1 on the left and right and fix them inside the pressing device. Subsequently, the front clamping plate 13 and the mold mechanism 1 approach each other, so that an injection space is formed between the fixed mold 15 and the inside of the mold mechanism 1. Subsequently, the discharging mechanism 2 performs injection molding. After cooling, the adjusting mechanism 3 reduces the contact surface between the side wall of the injection space and the finished product.

[0069] The mold mechanism 1 includes:

[0070] A support assembly 11, and the support assembly 11 is arranged on the side wall of the front clamping plate 13 through a support member;

[0071] The support member includes a rear mold clamping plate 111, and an air pressure box 112 is fixedly connected to the side wall of the rear mold clamping plate 111;

[0072] A driving assembly 12, and the driving assembly 12 is fixedly connected to the side wall of the air pressure box 112 through a driving member;

[0073] The driving member includes a bottom frame 121 fixedly connected to the side wall of the air pressure box 112, and a middle frame 122 is fixedly connected to the side wall of the bottom frame 121;

[0074] Among them, after the device is cooled, the discharging mechanism 2 will generate high pressure and transmit it to the injection space through the air pressure box 112 and the adjusting mechanism 3 to complete the demolding process of the device.

[0075] The discharging mechanism 2 includes:

[0076] An exhaust assembly 21, and the exhaust assembly 21 is fixedly connected to the side wall of the middle frame 122 through an air conveying member;

[0077] The air conveying member includes a feeding plate 211 penetratingly connected to the side wall of the middle frame 122, and an exhaust block 212 is fixedly connected to the outer wall of the middle frame 122;

[0078] An inflation assembly 22, and the inflation assembly 22 is fixedly connected to the inner wall of the air pressure box 112 through an inflation member;

[0079] The inflation member includes a pneumatic machine 221 penetratingly connected to the inner wall of the air pressure box 112;

[0080] Among them, before using this device, first fixedly connect the rear mold clamping plate 111 and the front clamping plate 13 inside a left and right moving pressing device, and ensure that the feeding plate 211 is at the bottom and the exhaust block 212 is at the top. Penetratingly connect the external air pipe and the material pipe to the feeding plate 211 to ensure that the external air pipe and the material pipe can transmit nitrogen and plastic melt to the injection space.

[0081] The adjusting mechanism 3 includes:

[0082] A control assembly 31, and the control assembly 31 is fixedly connected to the inner wall of the support assembly 11;

[0083] The closing component 32 is fixedly connected to the inner wall of the air pressure box 112 through a plugging member;

[0084] The plugging member includes a fixed sliding carriage 324 fixedly connected to the inner wall of the air pressure box 112. A plugging plate 325 is slidably connected to the inner wall of the fixed sliding carriage 324. A second spring 326 is fixedly connected to the inner wall of the plugging plate 325. One end of the second spring 326 away from the plugging plate 325 is fixedly connected to the inner wall of the second spring 326;

[0085] Among them, after the gas inside the air pressure box 112 is transmitted to the injection molding space through the control component 31, if the gas cannot be effectively discharged to the external environment, at this time, the plugging plate 325 will be in a stationary state. When the gas in the air pressure box 112 is directly transmitted to the external environment, the plugging plate 325 will be blocked to limit the continuous flow of the gas.

[0086] Example two, please refer to Figure 3 - Figure 11 , the present invention is an integrally formed mold for a fan blade frame. On the basis of Example one, the support component 11 includes a fixed block 113 fixedly connected to the side wall of the air pressure box 112. The outer wall of the fixed block 113 is fixedly connected to the inner wall of the through hole of the bottom frame 121;

[0087] Among them, the air compressor 221 injects gas into the air pressure box 112. The air pressure box 112 injects high-pressure gas into the injection molding space through the fixed block 113 and the adjusting mechanism 3 to assist the demolding process of the auxiliary equipment;

[0088] The external air pipe supplements nitrogen into the injection molding space. Since the mass of nitrogen is greater than the mass of air, the air in the injection molding space will be discharged outward through the exhaust block 212. Subsequently, the plastic melt enters the injection molding space through the feed plate 211 and gradually fills the internal space. And the excess part of the plastic melt will overflow outward through the exhaust block 212. Subsequently, the equipment enters the cooling process to ensure that the equipment is in a stationary state.

[0089] The driving component 12 includes a plurality of movable mold cylinders 123 fixedly connected to the side wall of the bottom frame 121. The output ends of the plurality of movable mold cylinders 123 are fixedly connected to a movable mold 124;

[0090] Among them, during use, each movable mold cylinder 123 drives the movable molds 124 to gather together, and makes the plurality of movable molds 124 form a circular shape, presenting a state as Figure 4 . Subsequently, the pressing device drives the front clamping plate 13 and the rear mold clamping plate 111 to approach each other, so that an injection molding space is formed among the hollow mold 213, the fixed mold one 15 and the movable mold 124.

[0091] The exhaust assembly 21 includes a hollow mold 213 fixedly connected to the outer wall of the fixed block 113, and an electric push block 214 is fixedly connected to the side wall of the bottom frame 121;

[0092] Among them, after the mold is cooled, when the front clamping plate 13 is separated from the rear mold clamping plate 111, and each movable mold cylinder 123 drives the movable mold 124 away from the side wall of the finished product, the electric push block 214 will extend and push the material outwards;

[0093] When the equipment needs to demold, each movable mold cylinder 123 will drive the corresponding movable mold 124 away from the side wall of the finished product, reducing the contact area between the movable mold 124 and the finished product. As the pressing device forces the front clamping plate 13 to separate from the rear mold clamping plate 111, at this time, the fixed mold one 15 will separate from the outer surface of the finished product. Through the application of the above components, when the equipment demolds, the contact surface between the finished product and the inner wall of the mold is reduced, and the resistance effect on the fan blade during demolding is reduced.

[0094] The inflation assembly 22 includes an exhaust port 222 opened on the inner wall of the air pressure box 112, and an exhaust through hole 223 is opened on the inner wall of the fixed block 113;

[0095] Among them, the high-pressure gas blown out by the air pressure box 112 will be transmitted to the injection molding space through the exhaust port 222 and the exhaust through hole 223, reducing the contact surface between the finished product and the inner wall of the mold during mold demolding;

[0096] Utilizing the characteristic that the above high-pressure gas flows outwards from the gap, a blocking plate 325 is provided inside the equipment. Among them, before the blocking plate 325 is used, under the push of the second spring 326, there will be a small air-interconnected gap between the blocking plate 325 and the exhaust through hole 223. When the high-pressure gas acts on the side wall of the product but does not communicate with the external environment, at this time, the adhesion position between the finished product and the fan blade, as well as the inner wall of the hollow mold 213, will be in a sealed state. At this time, the high-pressure gas only generates thrust and no flow force; after the high-pressure gas completes the separation of a single fan blade from the outer wall of the hollow mold 213, at this time, the high-pressure gas will pass through the exhaust through hole 223 from the air pressure box 112 and Figure 9 flow out through the gap G. The flow force generated during this process will force the blocking plate 325 to move towards the exhaust through hole 223 and block the exhaust through hole 223. Through the application of the above components, when the high-pressure gas is used for demolding, after a single hollow mold 213 is demolded, the corresponding blocking plate 325 will block the exhaust through hole 223, preventing the demolded hollow mold 213 from discharging gas again, and avoiding the pressure drop of gas demolding in the remaining hollow molds 213 due to gas loss in a single hollow mold 213, which affects the demolding efficiency of the remaining hollow molds 213.

[0097] The control component 31 includes a first spring 311 fixedly connected to the top of the fixed block 113. One end of the first spring 311 away from the fixed block 113 is fixedly connected to a fixed plate 312. The bottom of the fixed plate 312 is fixedly connected to a sliding block 313. The outer wall of the sliding block 313 is slidably connected to the inner wall of the exhaust through-hole 223. An exhaust groove 314 is formed at the bottom of the sliding block 313.

[0098] When the air pressure inside the air pressure box 112 increases, the high-pressure gas will force the sliding block 313 to slide upward along the inner wall of the exhaust through-hole 223, and enter the inner wall of the hollow mold 213 through the gap between the exhaust groove 314 and the exhaust through-hole 223.

[0099] After all the hollow molds 213 are demolded by air pressure, the contact surface between the side wall of the fan blade and the inner wall of the mold will be smaller at this time. Then, the power supply of the electric push block 214 is turned on, so that the electric push block 214 extends, forcing the electric push block 214 to drive the finished product to completely separate from the inner wall of the mold, completing the demolding process of the equipment. At this time, the air compressor 221 stops running, and with the disappearance of the high-pressure gas, the second spring 326 drives the blocking plate 325 to reset, and each first spring 311 drives the fixed plate 312 to reset. The reset fixed plate 312 forces the shielding arc plate 323 to re-block the air outlet groove 321 through the inclined rod 322.

[0100] The closing component 32 includes two air outlet grooves 321 formed on the side wall of the hollow mold 213. A shielding arc plate 323 is rotatably connected to the inner walls of the two air outlet grooves 321. An inclined rod 322 is rotatably connected to the side wall of the fixed plate 312. One end of the inclined rod 322 away from the fixed plate 312 is rotatably connected to the inner wall of the shielding arc plate 323.

[0101] When the sliding block 313 drives the fixed plate 312 to move upward, the inclined rod 322 will drive the shielding arc plate 323 to move a small range in the direction of the fixed plate 312 with the connection point as the center. At this time, the high-pressure gas will directly act on the side wall of the finished product.

[0102] When the front clamping plate 13 is separated from the rear mold clamping plate 111, the air compressor 221 will generate high-pressure gas and transmit it to the inner wall of the air pressure box 112. At this time, with the increase of pressure, the high-pressure gas will push the sliding block 313 to move along the inner wall of the exhaust through-hole 223 towards the hollow mold 213, forcing the sliding block 313 to drive the fixed plate 312 to move synchronously. As Figure 9 shown, the fixed plate 312 drives the shielding arc plate 323 to rotate with the connection point as the center through the inclined rod 322, so that a small gap appears between the shielding arc plate 323 and the air outlet groove 321, presenting the state of G as shown in Figure 9 By applying the above components, the contact surface between the shielding arc plate 323 and the finished product is reduced, and the resistance received by the finished product during demolding is reduced.

[0103] The feature that there is a gap between the above-mentioned shielding arc plate 323 and the air outlet groove 321 is that when high-pressure gas enters the interior of the hollow mold 213, the high-pressure gas will directly act on the side wall of the finished product through the above gap. Through the pushing of the high-pressure gas, the finished product adhered to the side wall of the hollow mold 213 will receive an outward thrust, causing the outer wall of the finished product fan blade to move away from the side wall of the hollow mold 213, greatly reducing the contact area between the finished product fan blade and the inner wall of the mold.

[0104] A specific application of this embodiment is: before using the device, first fixedly connect the rear mold clamping plate 111 and the front clamping plate 13 inside the left-right moving pressing device, and ensure that the feeding plate 211 is at the bottom and the exhaust block 212 is at the top. Connect the external air pipe and the material pipe to penetrate through the feeding plate 211 to ensure that the external air pipe and the material pipe can transmit nitrogen and plastic melt to the injection space;

[0105] Subsequently, during use, each movable mold cylinder 123 drives the movable molds 124 to gather together with each other, and makes the plurality of movable molds 124 form a circular shape, presenting a state as Figure 4 shown in, and then the pressing device drives the front clamping plate 13 and the rear mold clamping plate 111 to approach each other, so that an injection space is formed among the hollow mold 213, the fixed mold one 15 and the movable molds 124;

[0106] Subsequently, the external air pipe replenishes nitrogen into the injection space. Since the mass of nitrogen is greater than the mass of air, the air in the injection space will be discharged outward through the exhaust block 212. Subsequently, the plastic melt enters the interior of the injection space through the feeding plate 211 and gradually fills the internal space, and the excess part of the plastic melt will overflow outward through the exhaust block 212. Subsequently, the device enters the cooling process to ensure that the device is in a stationary state;

[0107] When the device needs to demold, each movable mold cylinder 123 will drive the corresponding movable mold 124 away from the side wall of the finished product, reducing the contact area between the movable mold 124 and the finished product. As the pressing device forces the front clamping plate 13 and the rear mold clamping plate 111 to separate, at this time, the fixed mold one 15 will separate from the outer surface of the finished product. Through the application of the above components, when the device demolds, the contact area between the finished product and the inner wall of the mold is reduced, and the resistance effect on the finished product during demolding is reduced.

[0108] Among them, when the front clamping plate 13 and the rear mold clamping plate 111 separate, the air compressor 221 will generate high-pressure gas and transmit it to the inner wall of the air pressure box 112. At this time, as the pressure increases, the high-pressure gas will push the sliding block 313 to move along the inner wall of the exhaust through hole 223 towards the direction of the hollow mold 213, forcing the sliding block 313 to drive the fixing plate 312 to move synchronously, as Figure 9As shown, the fixed plate 312 drives the shielding arc plate 323 to rotate around the connection point through the tilt rod 322, so that a small gap appears between the shielding arc plate 323 and the air outlet groove 321, showing as Figure 9 In the state of middle G, the contact area between the shielding arc plate 323 and the finished product is reduced through the application of the above components, thereby reducing the resistance encountered by the finished product during demolding.

[0109] By utilizing the gap between the shielding arc plate 323 and the gas outlet groove 321, when the high-pressure gas enters the hollow mold 213, the high-pressure gas will directly act on the side wall of the finished product through the gap. The high-pressure gas pushes the finished product adhering to the side wall of the hollow mold 213 to receive an outward thrust, so that the outer wall of the finished fan blade is away from the side wall of the hollow mold 213, greatly reducing the contact surface between the finished fan blade and the inner wall of the mold;

[0110] Taking advantage of the characteristic that the high-pressure gas flows outward from the gap, a blocking plate 325 is arranged inside the equipment. Before use, the blocking plate 325 is pushed by the spring 2 326, and there will be a gap for air communication between the blocking plate 325 and the exhaust hole 223, and the gap is small. When the high-pressure gas acts on the side wall of the product but does not circulate with the external environment, the adhesion position of the finished product and the fan blade, as well as the inner wall of the hollow mold 213, will be in a closed state. At this time, the high-pressure gas only generates thrust, and there is no flow force. After the high-pressure gas completes the separation of a single fan blade from the outer wall of the hollow mold 213, the high-pressure gas will flow out from the air pressure box 112 through the exhaust hole 223 and Figure 9 The gas flows outward from the gap G. The flow force generated in this process will force the blocking plate 325 to move toward the exhaust through hole 223 and block the exhaust through hole 223. Through the application of the above components, when the high-pressure gas is demoulded, after a single hollow mold 213 is demoulded, the corresponding blocking plate 325 will block the exhaust through hole 223, so that the hollow mold 213 that has been demoulded cannot discharge gas outward again, avoiding the gas loss of a single hollow mold 213, causing the pressure of gas demoulding of the remaining hollow molds 213 to drop, affecting the demoulding efficiency of the remaining hollow molds 213;

[0111] After all hollow molds 213 have completed air pressure demolding, the contact area between the side wall of the fan blade and the inner wall of the mold will be smaller. At this time, the power of the electric ejection block 214 is turned on, so that the electric ejection block 214 is extended, forcing the electric ejection block 214 to drive the finished product to completely separate from the inner wall of the mold, completing the demolding process of the equipment. At this time, the air compressor 221 stops running, the high-pressure gas disappears, the spring 2 326 drives the blocking plate 325 to reset, and each spring 1 311 drives the fixed plate 312 to reset, and the reset fixed plate 312 forces the shielding arc plate 323 to re-block the air outlet groove 321 through the tilting rod 322.
