Description

Technical Field

[0001] The invention relates to the technical field of injection molding machine equipment, in particular to a quick mold changing device for an injection molding machine and a use method thereof. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity;

[0003] When the waste from injection molding needs to be crushed before recycling, the general crushing method is to apply pressure to the material through the crushing roller, so that the material is crushed due to the gradually increasing pressure. This crushing method mainly relies on a single force application method, which can easily lead to local accumulation of waste when pressure is applied to the waste for crushing. When pressure is applied to the waste, the waste is easy to jump, making it difficult to crush the waste evenly. It takes a long time to crush the waste, and it is easy to cause uneven particle size of the crushed waste, affecting the subsequent recycling and the crushing efficiency of the waste.

[0016] Furthermore, a method for using a quick mold changing device for an injection molding machine, the quick mold changing device for an injection molding machine, the method comprising the following steps:

[0017] S1: First, connect the pipe with the exhaust fan to the discharge pipe at the bottom of the discharge box, then start the motor, and then transport the waste generated after injection molding through the discharge box to the working box through the external conveying equipment;

[0018] S2: When the waste is transported into the working box, the motor drives the two fixed rings 2 to drive multiple intermediate shafts to rotate. When the fixed rings 2 rotate, multiple obtuse-angle rods are driven to rotate synchronously, and the waste is sheared by the tool during the rotation.

[0019] S3: When the obtuse-angle rod rotates, the connecting plate and the middle rod will drive the arc-shaped cutting plate to rotate back and forth and perform extrusion shearing and crushing on the waste. After that, the crushed waste will be transported to the heating and melting device through a pipe connected to the discharge pipe for recycling.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the motor drives the transmission roller to rotate, the rotation of the transmission roller will drive the two fixed rings to rotate synchronously. When the two fixed rings rotate, they will also drive multiple intermediate shafts to rotate synchronously. Then, when the fixed ring rotates, the rotation of the fixed ring will drive multiple obtuse-angle rods to rotate synchronously. When the fixed ring drives multiple obtuse-angle rods to rotate synchronously, the long rods on the multiple obtuse-angle rods will be squeezed by the protrusions on the T-shaped rods and move relative to each other. When the two obtuse-angle rods rotate relative to each other, the relative rotation of the obtuse-angle rods will drive the tool to shear the waste. At the same time, when the obtuse-angle rods rotate relative to each other, the rotation of the obtuse-angle rods will drive multiple arc cutting plates through the intermediate rods to deflect them on the surface of the intermediate rods. Then, when the fixed ring drives multiple intermediate shafts to rotate, the rotation of the intermediate shafts will contact the inner wall of the fixed ring through the rotating wheel and drive the intermediate shafts to rotate through friction when the fixed ring rotates. When the wheel rotates, the rotation of the wheel will reciprocally squeeze the arc block on the rotating disk through the raised rod. When the raised rod squeezes the rotating disk, the rotating disk will deflect on the surface of the wheel. When the rotating disk deflects reciprocally, the deflection of the rotating disk will drive the connecting frame 1 and the connecting frame 2 to slide back and forth in an alternating manner through the intermediate plate. When the connecting frame 2 and the connecting frame 1 slide back and forth in an alternating manner, the sliding of the connecting frame 1 and the connecting frame 2 will drive multiple arc-shaped cutting plates to deflect each other. When multiple arc-shaped cutting plates are deflected, the deflection of the arc-shaped cutting plates will reciprocally squeeze the waste, and at the same time, it will cut again to evenly crush the waste. Compared with the traditional crushing method, the relative rotation of the obtuse-angle rod and the reciprocating movement and swinging of the arc-shaped cutting plates can make the waste subject to multi-directional crushing in the working box, which can not only accelerate the crushing of the waste, but also change the uniformity of the waste crushing, thereby improving the crushing effect and stability.

[0022] 2. In the present invention, when the arc cutting plate moves back and forth, the reciprocating movement of the arc cutting plate will squeeze the arc plate, so that the arc plate expands and contracts with the movement of the arc cutting plate. When the arc plate expands and contracts, the movement of the arc plate will drive the empty slot plate through the piston box to move the empty slot plate up and down. Then, when the arc plate contracts and expands, it will also drive the elastic plate to shake. When shaking, the elastic plate will drive the rotating frame to shake synchronously. When the rotating frame shakes, the shaking of the rotating frame will drive the rotating block to shake synchronously through the rotating block. When shaking, the toothed disc will drive the jet pipe to hit the bottom of the empty slot plate. The empty slot plate vibrates after being hit. The vibration of the empty slot plate can break and disperse the waste accumulation or pushing between the two arc cutting plates. Through the up and down movement and vibration of the flexible plate, the pushing of the waste during crushing is reduced, so that the waste can be effectively crushed and dispersed during crushing, thereby being easier to be crushed and dispersed, thereby improving the crushing efficiency.

[0023] 3. In the present invention, when the arc plate expands and contracts, the contraction of the arc plate will push the piston rod so that the piston rod slides on the inner wall of the piston box and squeezes the gas inside the piston box. When the gas inside the piston box is squeezed, it will enter the jet pipe through the connecting pipe. At the same time, when the piston rod slides in the piston box, the sliding of the piston rod will drive the flexible joint to rotate synchronously through friction. When the flexible joint rotates, it will drive the toothed disc to rotate through the bevel gear at the extension end. When the toothed disc rotates, it will drive the jet pipe to rotate synchronously. When the toothed disc drives the jet pipe to rotate, the shaking of the elastic plate will drive the two rotating frames to move back and forth relative to each other. When the rotating frames move relatively, the movement of the rotating frames will push the toothed disc through the rotating block so that the two toothed discs move relatively. When the two toothed discs move relatively, the movement of the toothed disc will push the piston rod to rotate. The second piston rod squeezes the gas inside the second piston box. When the gas in the second piston box is squeezed, it will enter into the multiple jet pipes through the crushing mechanism. When the gas inside the piston box and the second piston box enters into the jet pipe, the squeezing of the second piston rod will cause the gas to be ejected through the multiple toothed discs and form a jet flow. At this time, the jetted airflow can blow the waste pushed on the empty slot plate, which can further disperse the distribution of the waste. At the same time, when the airflow blows upward, the blowing of the gas can make the waste that has been broken into smaller particles blow upward, and the larger particles of waste remain on the surface of the empty slot plate, so that the arc cutting plate can reciprocate and crush it, and can also wash away the waste particles attached to the surface of the arc cutting plate or the empty slot plate, further reducing the blockage and pushing of the waste, and improving the crushing efficiency.

When the fixed ring 203 drives the multiple obtuse-angle rods 301 to rotate synchronously, the long rods 302 on the multiple obtuse-angle rods 301 will be squeezed by the protrusions 103 and the protrusions on the T-bar 102 to move relative to each other. When the two obtuse-angle rods 301 rotate relative to each other, the relative rotation of the obtuse-angle rods 301 will drive the cutter to shear the waste. At the same time, when the obtuse-angle rods 301 rotate relative to each other, the rotation of the obtuse-angle rods 301 will drive the multiple arc-shaped cutting plates 505 through the intermediate rods 304 to deflect on the surface of the intermediate rods 304. Then, when the fixed ring 203 drives the multiple intermediate shafts 401 to rotate, the rotation of the intermediate shafts 401 will contact the inner wall of the fixed ring 104 through the rotating wheel 402 and drive the intermediate shafts 401 through the friction force when the fixed ring 203 rotates. When the rotating wheel 402 rotates, the rotation of the rotating wheel 402 will reciprocately squeeze the arc block on the rotating disk 501 through the protruding rod 404. When the protruding rod 404 squeezes the rotating disk 501, the rotating disk 501 will deflect on the surface of the rotating wheel 402. When the rotating disk 501 deflects back and forth, the deflection of the rotating disk 501 will drive the connecting frame 1 503 and the connecting frame 2 504 to slide back and forth through the middle plate 502. When the connecting frame 2 504 and the connecting frame 1 503 slide back and forth, the connecting frame 1 503 and the connecting frame 2 504 will slide back and forth. The sliding of frame 2 504 will drive multiple arc-shaped cutting plates 505 to deflect relative to each other. When multiple arc-shaped cutting plates 505 are deflected, the deflection of the arc-shaped cutting plates 505 will reciprocately squeeze the waste, and at the same time, they will cut again to evenly crush the waste. Compared with the traditional crushing method, the relative rotation of the obtuse-angle rod 301 and the reciprocating movement and swinging of the arc-shaped cutting plates 505 can make the waste subject to multi-directional crushing in the working box 101, which can accelerate the crushing of the waste and change the uniformity of the waste crushing, thereby improving the crushing effect and stability.

[0055] When the arc cutting plate 505 moves back and forth, the reciprocating movement of the arc cutting plate 505 will squeeze the arc plate 602, so that the arc plate 602 expands and contracts with the movement of the arc cutting plate 505. When the arc plate 602 expands and contracts, the movement of the arc plate 602 will drive the empty slot plate 605 through the piston box 604, so that the empty slot plate 605 moves up and down. Then, when the arc plate 602 contracts and expands, it will also drive the elastic plate 701 to shake. When the elastic plate 701 shakes, it will drive the rotating frame 702 to shake synchronously. When the rotating frame 702 shakes When the rotating frame 702 moves, the shaking of the rotating block 704 will drive the rotating block 704 to shake synchronously through the rotating block 704. When the toothed disc 705 shakes, it will drive the jet pipe 803 to hit the bottom of the empty slot plate 605. The empty slot plate 605 vibrates after being hit. The vibration of the empty slot plate 605 can break and disperse the waste accumulation or pushing between the two arc-shaped cutting plates 505. The up and down movement and vibration of the flexible plate can reduce the pushing of the waste during crushing, so that the waste can be effectively crushed and dispersed during crushing, making it easier to be crushed and dispersed, thereby improving the crushing efficiency.

[0056] When the arc plate 602 expands and contracts, the contraction of the arc plate 602 pushes the piston rod 603 so that the piston rod 603 slides on the inner wall of the piston box 604 and squeezes the gas inside the piston box 604. When the gas inside the piston box 604 is squeezed, it enters the injection pipe 803 through the connecting pipe 706. At the same time, when the piston rod 603 slides in the piston box 604, the sliding of the piston rod 603 drives the flexible joint 703 to rotate synchronously through friction. When the toothed disc 705 rotates, the bevel gear at the extended end will drive the toothed disc 705 to rotate. When the toothed disc 705 rotates, the jet tube 803 will rotate synchronously. When the toothed disc 705 drives the jet tube 803 to rotate, the shaking of the elastic plate 701 will drive the two rotating frames 702 to move back and forth relative to each other. When the rotating frames 702 move relatively, the movement of the rotating frames 702 will push the toothed disc 705 through the rotating block 704 so that the two toothed discs 705 move relatively. When the two toothed discs 705 move relatively, the toothed disc 705 The movement of the disc 705 will push the piston rod 802 so that the piston rod 802 squeezes the gas inside the piston box 801. When the gas inside the piston box 801 is squeezed, it will enter the multiple jet pipes 803 through the 80 crushing mechanism 5. When the gas inside the piston box 604 and the piston box 801 enters the inside of the jet pipe 803, the squeezing of the piston rod 802 will cause the gas to be ejected through the multiple toothed discs 705 and form a jet flow. At this time, the jetted airflow can Blowing the waste pushed on the empty slot plate 605 can further disperse the distribution of the waste. At the same time, when the airflow blows upward, the blowing of the gas can make the already broken smaller waste blow upward, and the larger particles of waste remain on the surface of the empty slot plate 605, so that the arc cutting plate 505 can reciprocate and crush it for the second time, and can also wash away the waste particles attached to the surface of the arc cutting plate 505 or the empty slot plate 605, further reducing the blockage and pushing of the waste and improving the crushing efficiency.
