Description

Technical Field

[0001] The invention relates to the technical field of injection molding equipment, in particular to an injection molding machine for plastic processing with an auxiliary demoulding structure. Background Art

[0002] Injection molding machines are widely used processing machines in the plastic processing industry. Not only can a large number of products be directly produced by injection molding machines, but they are also key equipment in the injection stretch blow molding process. Injection molding machines are also known as injection molding machines or injection machines. They are the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machines can be divided into vertical, horizontal, and vertical-horizontal composite types according to the arrangement of the injection device and the clamping device. Injection molding machines can heat plastics and apply high pressure to molten plastics to make them ejected and fill the mold cavity. With the continuous development of science and technology, the rapid progress of society, and the trend of integrated molding, the demand for injection molding machines is also increasing, and the use of injection molding machines is also increasing.

[0003] At present, the existing plastic processing injection molding machines are easily affected by external forces and vibrations during use, which makes the injection barrel on the injection molding machine and the gate sleeve on the mold unstable. Moreover, after the injection molding is completed, there is still material at the discharge port of the injection barrel, which makes demolding inconvenient. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an injection molding machine for plastic processing with an auxiliary demoulding structure, comprising: A frame, the frame having a supporting frame body, and an injection mold and a hydraulic cylinder are respectively installed at two ends of the top of the frame; The plastic processing injection molding machine with auxiliary demoulding structure also includes: An injection molding mechanism, which is used to inject raw materials, and is installed on the top of the frame, and is installed just above the hydraulic cylinder; Wherein, the injection mechanism comprises an injection mainframe and a circular groove, the injection mainframe is slidably mounted on the top of the frame, the circular groove is opened on the outside of the injection mold, an injection barrel is mounted in the middle of the outside of the injection mainframe, a right-angle frame is fixedly mounted on the discharge end of the outside of the injection barrel, a positioning block is slidably mounted on the top of the right-angle frame, a clamping ball is fixedly mounted on the end of the positioning block away from the right-angle frame, a diamond-shaped elastic frame is fixedly mounted between the outside of the positioning block and the top of the right-angle frame, a push rod is fixedly mounted on the side of the outside of the positioning block, and an auxiliary component is mounted on the outside of the right-angle frame, and the injection mainframe can be driven to move to the left as a whole by contracting the output end of the hydraulic cylinder, so that the injection barrel moves with the injection mainframe, and under the support of the right-angle frame, the positioning block continuously moves to the side close to the circular groove, and the clamping ball is embedded in the circular groove, so that the positioning block is further positioned; As the injection molding barrel continues to move to the left, the diamond-shaped elastic frame is compressed, and is symmetrically installed along the injection molding barrel in combination with two right-angle frames, so that the injection molding barrel is supported, and the injection molding barrel is not easily affected by external forces and vibrations. The injection molding barrel and the sprue sleeve on the injection mold have good overall stability, which facilitates the cooperation between the two, thereby facilitating accurate injection molding; The auxiliary component includes a sliding bar, which is slidably installed in the middle of the right-angle frame, and a U-shaped rod is fixedly installed on the top of the sliding bar, and a baffle is fixedly installed on the side of the outer side of the sliding bar through a bent rod, and the baffle is installed at the discharge port of the injection molding barrel, and a round tube is fixedly installed on the side of the outer side of the baffle, and an air channel is opened inside the baffle, and the top of the air channel is connected with the air outlet end of the round tube, and a right-angle elastic strip is fixedly installed between the outer side of the sliding bar and the outer side of the injection molding barrel. When the right-angle frame is moved to the left by the injection molding barrel, and the positioning block is subjected to the reverse force of the injection mold, and is tilted by using the push rod, the push rod applies an upward pulling force to the U-shaped rod, so that the sliding bar slides upward, and the right-angle elastic strip is stretched. At this time, the two baffles blocked at the discharge port of the injection molding barrel move outward, thereby opening the discharge port of the injection molding barrel and facilitating the insertion of the discharge port of the injection molding barrel into the gate sleeve on the injection mold.

[0005] Preferably, the position of the locking ball corresponds to the position of the circular groove, which facilitates the cooperation between the locking ball and the circular groove. The positioning block and the circular groove are installed at the same height, and the push rod is installed at an angle to facilitate the application of force.

[0006] Preferably, the air ducts are evenly distributed inside the baffle, there are two right-angle elastic strips, and the two right-angle elastic strips are symmetrically installed along the sliding bar. The two symmetrical right-angle elastic strips can be used together to elastically support the sliding bar so that the sliding bar is subjected to balanced force.

[0007] The output end of the hydraulic cylinder is extended, and the output end of the hydraulic cylinder pushes the injection main unit and the injection barrel to the right. At this time, the positioning block moves to the side away from the injection mold, and the reverse force of the injection mold on the positioning block disappears. Under the elastic force of the diamond elastic frame, the push rod moves to the side away from the U-shaped rod. At this time, the force of the push rod on the U-shaped rod disappears. At this time, the right-angle elastic bar will exert a downward elastic pulling force on the sliding bar, so that the sliding bar drives the baffle to move in the opposite direction for reset. At this time, the two symmetrical baffles merge to cut off the molten plastic raw material at the discharge port of the injection barrel, and the discharge port of the injection barrel is blocked, which makes it less likely for the raw material to be pulled by wire drawing, thereby assisting the demolding of the injection barrel and the injection mold.

[0008] The cylinder is installed on the surface of the injection molding barrel to form a hollow layer between the injection molding barrel and the cylinder, thereby insulating the injection molding barrel and reducing the injection molding barrel's insulation of the molten plastic, reducing heat dissipation, and reducing temperature differences, making it less likely for the temperature difference to be too large and cause solidification.

[0009] Preferably, a heat preservation component is installed in the middle of the outer side of the injection molding barrel, and the heat preservation component includes a cylinder and a heat conductive sheet. The cylinder is sleeved on the outer side of the injection molding barrel, and the cylinder is fixedly installed between the cylinder and the injection molding barrel. The heat conductive sheet is fixedly installed on the outer side of the injection molding barrel, and the heat conductive sheet is installed inside the cylinder. A hair dryer is installed at the bottom of the cylinder, and the air outlet end of the hair dryer extends to the inside of the cylinder. A guide plate is fixedly installed in the middle of the outer side of the heat conductive sheet. The top and bottom of the cylinder and the position close to the discharge port of the injection molding barrel are connected with a connecting pipe. The end of the connecting pipe away from the cylinder is connected with the air inlet end of the round pipe. The heat conductive sheet can be used for heat transfer to heat the air in the cylinder. At the same time, a hair dryer is used as the power to blow air into the cylinder through the air outlet of the hair dryer. Combined with the spiral shape of the heat conducting plate, the hot air moves to the left along the surface of the injection molding barrel under the swirl guiding effect of the heat conducting plate. The guide plate is tilted to make the hot air close to the surface of the injection molding barrel, further promoting the insulation of the injection molding barrel.

[0010] Preferably, the heat conducting sheet is spiral-shaped, which can make the hot air flow in a spiral manner and increase the flow time. The guide plates are installed at an angle and are evenly distributed on the outside of the heat conducting sheet.

[0011] As the hair dryer blows, the hot air in the cylinder moves to the left, and under the transportation of the connecting pipe, the hot air enters the round tube and flows out through the airway, thereby making the air flow fluid. At this time, the heat of the hot air is transferred to the baffle, which makes the baffle rise steadily, and can reduce the temperature difference between the baffle and the raw material at the discharge port of the injection barrel, so that the raw material is not easy to solidify on the surface of the baffle, so that the heat is fully recovered and reused, and the structure is connected together.

[0012] Preferably, the cylinder is a closed cylindrical cylinder, the connecting pipe is a hose, and the hair dryer is installed directly below the cylinder.

[0013] Preferably, a feeding mechanism is installed at the feed port at the top of the injection molding barrel, and the feeding mechanism includes a storage bin, the storage bin is installed at the feed port at the top of the injection molding barrel, a hopper is installed at the side of the outer side of the storage bin, a servo motor is installed in the middle of the top of the storage bin, and a connecting roller is rotatably installed in the middle of the inside of the injection molding barrel, the top of the connecting roller and the output end of the servo motor are fixedly installed through a coupling, a toggling blade is fixedly installed at the bottom of the connecting roller, a square rod is fixedly installed at the bottom of the toggling blade, and a strong magnetic block is fixedly installed at the bottom of the square rod, and a sorting module is installed inside the storage bin and near the bottom, and the connecting roller is driven to rotate by the rotation of the output end of the servo motor. At this time, the toggling blade will rotate with the connecting roller and put the plastic raw material from the hopper into the storage bin. At this time, the rotating toggling blade will toggle the falling plastic raw material, so that the plastic raw material has a splash, and it is not easy to have uneven material dispersion.

[0014] Preferably, the moving blades are evenly distributed at the bottom of the connecting roller, and the square rod is installed at an angle.

[0015] Preferably, the sorting module comprises a disc and a triangular swing plate, the outer edge of the disc is fixedly mounted on the inner wall of the storage bin, the outer side of the triangular swing plate is rotatably mounted between the inner wall of the storage bin, a leakage hole is provided on the top of the disc, a V-shaped rod is fixedly mounted on the bottom end of the triangular swing plate, a spring is fixedly mounted between the bending part of the outer side of the V-shaped rod and the outer side of the triangular swing plate, a magnetic ball is fixedly mounted in the middle of the outer side of the spring, the magnetic ball and the strong magnetic block are opposite poles, an elastic reset part is fixedly mounted between the outer side of the triangular swing plate and the inner wall of the storage bin, after the plastic raw materials are evenly spread on the disc, the plastic raw materials will leak down through the leakage hole, and the bulk materials will be sorted out; At the same time, the rotating toggle blade is connected through the square rod. At this time, the strong magnetic block will exert a toggle force on the triangular swing plate, so that the triangular swing plate rotates to adjust the angle, and the elastic reset part is compressed, so that the V-shaped rod is driven to move together, and the magnetic ball and the strong magnetic block are combined as opposite magnetic poles. The two meet to generate magnetic attraction, so that the magnetic ball is sucked upwards, and the spring is stretched; As the toggle blades continue to rotate, the strong magnetic block separates from the triangular swing plate. At this time, the magnetic attraction between the magnetic ball and the strong magnetic block disappears, and under the elastic pulling force of the spring, the magnetic ball moves downward, knocks the disc, causing the disc to vibrate, and combined with the elastic thrust of the elastic reset part, the triangular swing plate rotates in the opposite direction to drive the V-shaped rod to reset, thereby prompting the material to leak from the leakage hole, and it is not easy to get blocked.

[0016] Preferably, the triangular swing plate is installed directly above the disc, and the leakage holes are evenly distributed on the top of the disc.

[0017] The present invention provides an injection molding machine for plastic processing with an auxiliary demoulding structure. It has the following beneficial effects: 1. The plastic processing injection molding machine with auxiliary demoulding structure utilizes the contraction of the output end of the hydraulic cylinder to drive the injection host and the injection barrel to move to the left, so that the card ball can be embedded in the circular groove, so as to position the positioning block. As the injection barrel continues to move to the left, it is combined with two right-angle frames symmetrically installed along the injection barrel, so that the injection barrel is supported, and the injection barrel is not easily affected by external force and vibration. The injection barrel and the gate sleeve on the injection mold have good overall stability, which is convenient for the two to cooperate with each other, thereby facilitating accurate injection molding.

[0018] 2. The plastic processing injection molding machine with auxiliary demoulding structure uses a push rod for tilted installation. At this time, the push rod applies an upward pulling force to the U-shaped rod, so that the sliding bar slides upward and the right-angle elastic bar is stretched. At this time, the two baffles blocking the discharge port of the injection barrel move outward, thereby opening the discharge port of the injection barrel and facilitating the insertion of the discharge port of the injection barrel into the gate sleeve on the injection mold.

[0019] 3. The plastic processing injection molding machine with auxiliary demoulding structure can reset the push rod under the elastic force of the diamond elastic frame, and the right-angle elastic strip will apply a downward elastic pulling force to the sliding bar, so that the sliding bar drives the baffle to move in the opposite direction for reset. At this time, the two symmetrical baffles merge to cut off the molten plastic raw material at the discharge port of the injection molding barrel, and the discharge port of the injection molding barrel is blocked, which makes it less likely for the raw material to be pulled by wire drawing, thereby assisting the demoulding of the injection molding barrel and the injection mold.

[0020] Fourth, the plastic processing injection molding machine with auxiliary demoulding structure uses a cylinder installed on the surface of the injection molding barrel, so that a hollow layer is formed between the injection molding barrel and the cylinder, thereby insulating the injection molding barrel, reducing the injection molding barrel to keep the molten plastic warm, reducing heat dissipation, and reducing temperature differences, making it less likely to solidify due to excessive temperature differences.

[0021] 5. The plastic processing injection molding machine with auxiliary demoulding structure can transfer heat by using the heat conducting sheet to heat the air in the cylinder. At the same time, under the blowing of the hair dryer and combined with the spiral shape of the heat conducting sheet, the hot air moves to the left along the surface of the injection barrel under the swirl guiding effect of the heat conducting sheet, and the guide plate is inclined so that the hot air is close to the surface of the injection barrel, further promoting the insulation of the injection barrel.

[0022] 6. The plastic processing injection molding machine with auxiliary demoulding structure, with the blowing of the hair dryer, makes the hot air in the cylinder move to the left side, and under the transportation of the connecting pipe, the hot air enters the round tube and flows out through the airway, thereby making the air flow fluid. At this time, the heat of the hot air is transferred to the baffle, so that the baffle is stably raised, which can reduce the temperature difference between the baffle and the raw material at the discharge port of the injection barrel, thereby making it difficult for the raw material to solidify on the surface of the baffle, and fully recovering the heat for reuse.

[0023] 7. The plastic processing injection molding machine with auxiliary demoulding structure uses the output end of the servo motor to drive the connecting roller to rotate. At this time, the shifting blades will rotate with the connecting roller and put the plastic raw materials from the hopper into the storage bin. At this time, the rotating shifting blades will shift the falling plastic raw materials, so that the plastic raw materials can be spread and uneven material dispersion is not likely to occur.

[0024] 8. In the plastic processing injection molding machine with auxiliary demoulding structure, the magnetic ball and the strong magnetic block meet and generate magnetic attraction, so that the magnetic ball is sucked up by the upward magnetic force. As the paddle blades continue to rotate, the strong magnetic block is separated from the triangular swing plate. At this time, the magnetic attraction between the magnetic ball and the strong magnetic block disappears, and under the elastic tension of the spring, the magnetic ball moves downward and knocks the disc, causing the disc to vibrate. Combined with the elastic thrust of the elastic reset part, the triangular swing plate rotates in the opposite direction to drive the V-shaped rod to reset, thereby prompting the material to leak from the leakage hole, and it is not easy to be blocked.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. The first embodiment, as Figure 1-Figure 5 As shown, the present invention provides a technical solution: an injection molding machine for plastic processing with an auxiliary demoulding structure, comprising: A frame 1, the frame 1 having a supporting frame body, and an injection mold 2 and a hydraulic cylinder 3 are respectively installed at both ends of the top of the frame 1; The plastic processing injection molding machine with auxiliary demoulding structure also includes: An injection molding mechanism 4, which is used for injecting raw materials, is mounted on the top of the frame 1, and is mounted just above the hydraulic cylinder 3; The injection mechanism 4 includes an injection main unit 41 and a circular groove 42. The injection main unit 41 is slidably mounted on the top of the frame 1. The circular groove 42 is opened on the outside of the injection mold 2. An injection barrel 43 is installed in the middle of the outside of the injection main unit 41. A right-angle frame 44 is fixedly installed at the discharge end of the outside of the injection barrel 43. A positioning block 45 is slidably mounted on the top of the right-angle frame 44. A card ball 46 is fixedly installed at one end of the positioning block 45 away from the right-angle frame 44. A diamond-shaped elastic frame is fixedly installed between the outside of the positioning block 45 and the top of the right-angle frame 44. 47, a push rod 48 is fixedly installed on the side of the outer side of the positioning block 45, and an auxiliary component 49 is installed on the outer side of the right-angle frame 44. The staff turns on the hydraulic cylinder 3 to work, and the output end of the hydraulic cylinder 3 is contracted to drive the injection host 41 to move to the left as a whole, so that the injection barrel 43 moves with the injection host 41, and under the support of the right-angle frame 44, the positioning block 45 is continuously moved to the side close to the circular groove 42, and the ball 46 is embedded in the circular groove 42, so that the positioning block 45 is positioned; As the injection molding barrel 43 continues to move to the left, the diamond-shaped elastic frame 47 is compressed, and is symmetrically installed along the injection molding barrel 43 in combination with the two right-angle frames 44, so that the injection molding barrel 43 is supported, and the injection molding barrel 43 is not easily affected by external forces and vibrations. The injection molding barrel 43 and the sprue sleeve on the injection mold 2 have good overall stability, which facilitates the cooperation between the two, thereby facilitating accurate injection molding; The position of the locking ball 46 corresponds to the position of the circular groove 42, which facilitates the matching of the locking ball 46 and the circular groove 42. The positioning block 45 and the circular groove 42 are installed at the same height, and the push rod 48 is installed at an angle to facilitate the application of force.

[0028] The auxiliary component 49 includes a sliding bar 491, which is slidably mounted in the middle of the right-angle frame 44, a U-shaped rod 492 is fixedly mounted on the top of the sliding bar 491, a baffle 493 is fixedly mounted on the side of the outer side of the sliding bar 491 through a bending rod, the baffle 493 is mounted at the discharge port of the injection molding barrel 43, a round tube 494 is fixedly mounted on the side of the outer side of the baffle 493, an air duct 495 is opened inside the baffle 493, the top of the air duct 495 is connected to the air outlet end of the round tube 494, and the outer side of the sliding bar 491 is connected to the outer side of the injection molding barrel 43. A right-angle elastic strip 496 is fixedly installed in the middle. When the right-angle frame 44 is moved to the left by the injection barrel 43 and the positioning block 45 is subjected to the reverse force of the injection mold 2, and the push rod 48 is used to install it tilted, the push rod 48 applies an upward pulling force to the U-shaped rod 492, so that the sliding bar 491 slides upward, and the right-angle elastic strip 496 is stretched. At this time, the two baffles 493 blocking the discharge port of the injection barrel 43 move outward, thereby opening the discharge port of the injection barrel 43 and facilitating the insertion of the discharge port of the injection barrel 43 into the gate sleeve on the injection mold 2.

[0029] The air passage 495 is evenly distributed inside the baffle 493. There are two right-angle elastic strips 496, and the two right-angle elastic strips 496 are symmetrically installed along the sliding bar 491. The two symmetrical right-angle elastic strips 496 can be used together to elastically support the sliding bar 491, so that the sliding bar 491 is balanced in force.

[0030] When the injection is completed, the output end of the hydraulic cylinder 3 is extended. At this time, the output end of the hydraulic cylinder 3 pushes the injection host 41 and the injection barrel 43 to the right together. At this time, the positioning block 45 moves to the side away from the injection mold 2, and the reverse force of the injection mold 2 on the positioning block 45 disappears, and under the elastic force of the diamond elastic frame 47, the push rod 48 moves to the side away from the U-shaped rod 492. At this time, the force of the push rod 48 on the U-shaped rod 492 disappears. At this time, the right-angle elastic bar 496 will exert a downward elastic pulling force on the sliding bar 491, so that the sliding bar 491 drives the baffle 493 to move in the opposite direction for reset. At this time, the two symmetrical baffles 493 merge to cut off the plastic molten raw material at the discharge port of the injection barrel 43, and the discharge port of the injection barrel 43 is blocked, thereby assisting the demolding of the injection barrel 43 and the injection mold 2.

[0031] The cylinder 51 is installed on the surface of the injection barrel 43, so that a hollow layer is formed between the injection barrel 43 and the cylinder 51, so that the injection barrel 43 can be kept warm, reducing the injection barrel 43 to keep the molten plastic warm.

[0032] The second embodiment, as Figure 1-Figure 7 As shown, based on the first embodiment: A heat preservation component 5 is installed in the middle of the outer side of the injection molding barrel 43. The heat preservation component 5 includes a cylinder 51 and a heat conductive sheet 52. The cylinder 51 is sleeved on the outer side of the injection molding barrel 43 and is fixedly installed between the cylinder 51 and the injection molding barrel 43. The heat conductive sheet 52 is fixedly installed on the outer side of the injection molding barrel 43 and installed inside the cylinder 51. A hair dryer 53 is installed at the bottom of the cylinder 51. The air outlet end of the hair dryer 53 extends to the inside of the cylinder 51. A guide plate 54 is fixedly installed in the middle of the outer side of the heat conductive sheet 52. The top and bottom of the cylinder 51 and the position close to the discharge port of the injection molding barrel 43 are connected with a connecting pipe 55. The end of the connecting pipe 55 away from the cylinder 51 is connected with the air inlet end of the circular pipe 494. The heat conductive sheet 52 is installed inside the cylinder 51. At this time, the heat conductive sheet 52 can transfer heat to heat the air in the cylinder 51. At the same time, the hair dryer 53 is used as the power to blow air into the cylinder 51 through the air outlet end of the hair dryer 53, and the heat conducting plate 52 is spirally shaped. Under the swirl guiding effect of the heat conducting plate 52, the hot air moves to the left along the surface of the injection barrel 43, and the guide plate 54 is inclined to make the hot air close to the surface of the injection barrel 43, further promoting the heat preservation of the injection barrel 43.

[0033] The heat conducting sheet 52 is spiral-shaped, which can make the hot air flow in a spiral manner and increase the flow time. The guide plates 54 are installed at an angle, and the guide plates 54 are evenly distributed on the outside of the heat conducting sheet 52 .

[0034] As the hair dryer 53 blows, the hot air in the cylinder 51 moves to the left, and under the transportation of the connecting pipe 55, the hot air enters the circular tube 494 and flows out through the air duct 495, thereby making the air flow fluid. At this time, the heat of the hot air is transferred to the baffle 493, so that the baffle 493 is stably raised, which can reduce the temperature difference between the baffle 493 and the raw material at the discharge port of the injection barrel 43, thereby making it difficult for the raw material to solidify on the surface of the baffle 493.

[0035] The cylinder 51 is a closed cylindrical cylinder, the connecting pipe 55 is a hose, and the blower 53 is installed just below the cylinder 51 .

[0036] The third embodiment, as Figure 1-Figure 5 and Figure 8-Figure 9 As shown, based on the first embodiment: A feeding mechanism 6 is installed at the feeding port on the top of the injection molding barrel 43. The feeding mechanism 6 includes a storage bin 61. The storage bin 61 is installed at the feeding port on the top of the injection molding barrel 43. A hopper 62 is installed on the side of the outer side of the storage bin 61. A servo motor 63 is installed in the middle of the top of the storage bin 61. A connecting roller 64 is rotatably installed in the middle of the inside of the injection molding barrel 43. The top of the connecting roller 64 is fixedly installed with the output end of the servo motor 63 through a coupling. A toggle blade 65 is fixedly installed at the bottom of the connecting roller 64. The toggle blade A square rod 66 is fixedly installed at the bottom end of 65, and a strong magnetic block 67 is fixedly installed at the bottom end of the square rod 66. A sorting module 68 is installed inside the storage bin 61 and near the bottom. The staff turns on the servo motor 63 to work, and uses the rotation of the output end of the servo motor 63 to drive the connecting roller 64 to rotate. At this time, the stirring blade 65 will rotate with the connecting roller 64, and put the plastic raw material from the hopper 62 into the storage bin 61. At this time, the rotating stirring blade 65 will stir the falling plastic raw material.

[0037] The moving blades 65 are evenly distributed at the bottom of the connecting roller 64, and the square rod 66 is installed at an angle.

[0038] The sorting module 68 includes a disc 681 and a triangular swing plate 682. The outer edge of the disc 681 is fixedly installed on the inner wall of the storage bin 61, and the outer side of the triangular swing plate 682 is rotatably installed between the inner wall of the storage bin 61. A leakage hole 683 is opened on the top of the disc 681. A V-shaped rod 684 is fixedly installed on the bottom end of the triangular swing plate 682. A spring 685 is fixedly installed between the outer bending part of the V-shaped rod 684 and the outer side of the triangular swing plate 682. A magnetic ball 686 is fixedly installed in the middle of the outer side of the spring 685. The magnetic ball 686 and the strong magnetic block 67 are opposite magnetic poles. An elastic reset member 687 is fixedly installed between the outer side of the triangular swing plate 682 and the inner wall of the storage bin 61. After the plastic raw materials are evenly spread on the disc 681, the plastic raw materials will leak down through the leakage hole 683, and large pieces of materials will be sorted out.

[0039] The triangular swing plate 682 is installed just above the disc 681, and the leakage holes 683 are evenly distributed on the top of the disc 681. The rotating toggle blade 65 is connected through the square rod 66. At this time, the strong magnetic block 67 will apply a toggle force to the triangular swing plate 682, so that the triangular swing plate 682 rotates to adjust the angle, and the elastic reset member 687 is compressed, and the V-shaped rod 684 is driven to move together. The magnetic ball 686 and the strong magnetic block 67 are opposite magnetic poles, and the two meet to generate magnetic attraction, so that the magnetic ball 686 is sucked upward, and the spring 685 is stretched; As the paddle 65 continues to rotate, the strong magnetic block 67 separates from the triangular swing plate 682. At this time, the magnetic attraction between the magnetic ball 686 and the strong magnetic block 67 disappears, and under the elastic tension of the spring 685, the magnetic ball 686 moves downward, knocking the disc 681, causing the disc 681 to vibrate. Combined with the elastic thrust of the elastic reset member 687, the triangular swing plate 682 rotates in the opposite direction to drive the V-shaped rod 684 to reset, thereby causing the material to leak from the leakage hole 683.

[0040] When in use, the staff first turns on the servo motor 63 to work, and uses the rotation of the output end of the servo motor 63 to drive the connecting roller 64 to rotate. At this time, the toggling blade 65 will rotate with the connecting roller 64, and put the plastic raw material from the hopper 62 into the storage bin 61. At this time, the rotating toggling blade 65 will toggle the falling plastic raw material, and the rotating toggling blade 65 is connected through the square rod 66. At this time, the strong magnetic block 67 will apply a toggling force to the triangular swing plate 682, so that the triangular swing plate 682 rotates to adjust the angle, and the elastic reset member 687 is compressed, and the V-shaped rod 684 is driven to move together, and the magnetic ball 686 and the strong magnetic block 67 are combined with opposite magnetic poles. The two meet to generate magnetic attraction, so that the magnetic ball 686 is sucked up, and the spring 685 is stretched; As the toggle blade 65 continues to rotate, the strong magnetic block 67 separates from the triangular swing plate 682. At this time, the magnetic attraction between the magnetic ball 686 and the strong magnetic block 67 disappears, and under the elastic tension of the spring 685, the magnetic ball 686 moves downward to knock the disc 681, causing the disc 681 to vibrate. Combined with the elastic thrust of the elastic reset member 687, the triangular swing plate 682 rotates in the opposite direction to drive the V-shaped rod 684 to reset, thereby causing the material to leak from the leakage hole 683. At this time, the material leaking from the leaking hole 683 enters the injection main unit 41, and then the material is heated and melted; At this time, the staff starts the hydraulic cylinder 3 to work, and the output end of the hydraulic cylinder 3 is contracted to drive the injection main unit 41 to move to the left as a whole, so that the injection barrel 43 moves with the injection main unit 41, and under the support of the right-angle frame 44, the positioning block 45 is continuously moved to the side close to the circular groove 42, and the positioning ball 46 is embedded in the circular groove 42, so that the positioning block 45 is further positioned; When the right-angle frame 44 is moved to the left by the injection barrel 43, and the positioning block 45 is subjected to the reverse force of the injection mold 2, and the push rod 48 is used for tilting installation, the push rod 48 applies an upward pulling force to the U-shaped rod 492, so that the sliding bar 491 slides upward, and the right-angle elastic bar 496 is stretched. At this time, the two baffles 493 blocking the discharge port of the injection barrel 43 move outward, thereby opening the discharge port of the injection barrel 43, so that the discharge port of the injection barrel 43 is inserted into the gate sleeve on the injection mold 2; At the same time, as the injection barrel 43 continues to move to the left, the diamond-shaped elastic frame 47 is compressed, and combined with the two right-angle frames 44, it is symmetrically installed along the injection barrel 43, so that the injection barrel 43 is supported, so that the injection barrel 43 and the sprue sleeve on the injection mold 2 have good overall stability, which is convenient for the two to cooperate with each other. At this time, the molten material is injected into the sprue sleeve on the injection mold 2 through the injection barrel 43 through the injection host 41; The heat conducting sheet 52 is installed inside the cylinder 51. At this time, the heat conducting sheet 52 can transfer heat to heat the air in the cylinder 51. The hair dryer 53 is used as the power to blow air into the cylinder 51 through the air outlet of the hair dryer 53. In addition, the heat conducting sheet 52 is spiral-shaped. Under the swirl guiding effect of the heat conducting sheet 52, the hot air moves to the left along the surface of the injection barrel 43. The guide plate 54 is inclined so that the hot air is closely attached to the surface of the injection barrel 43, further promoting the heat preservation of the injection barrel 43. The cylinder 51 is installed on the surface of the injection barrel 43, so that a hollow layer is formed between the injection barrel 43 and the cylinder 51, so that the injection barrel 43 can be kept warm, and the injection barrel 43 can be reduced in the process of keeping the molten plastic warm. When the injection is completed, the output end of the hydraulic cylinder 3 is extended. At this time, the output end of the hydraulic cylinder 3 pushes the injection host 41 and the injection barrel 43 to the right together. At this time, the positioning block 45 moves to the side away from the injection mold 2, and the reverse force of the injection mold 2 on the positioning block 45 disappears, and under the elastic force of the diamond elastic frame 47, the push rod 48 moves to the side away from the U-shaped rod 492. At this time, the force of the push rod 48 on the U-shaped rod 492 disappears. At this time, the right-angle elastic bar 496 will exert a downward elastic pulling force on the sliding bar 491, so that the sliding bar 491 drives the baffle 493 to move in the opposite direction for reset. At this time, the two symmetrical baffles 493 merge to cut off the molten plastic raw material at the discharge port of the injection barrel 43, and the discharge port of the injection barrel 43 is blocked, thereby assisting the demolding of the injection barrel 43 and the injection mold 2; As the blower 53 blows, the hot air in the cylinder 51 moves to the left, and under the transport of the connecting pipe 55, the hot air enters the circular tube 494 and flows out through the air channel 495, thereby making the air flow fluid. At this time, the heat of the hot air is transferred to the baffle 493, so that the baffle 493 is stably raised, which can reduce the temperature difference between the baffle 493 and the raw material at the discharge port of the injection barrel 43, thereby making it difficult for the raw material to solidify on the surface of the baffle 493; After the injection molding is finally completed, the servo motor 63 can be stopped, and the cover plate outside the storage bin 61 can be opened to take out and process the bulk materials screened by the disc 681 so that they can be used next time.
