[0046] Example 2

[0047] Please refer to Figure 1 and Fig.14As shown, the melting mechanism 7 includes a melting tube 701, which is rotatably connected to the inside of the fixed plate 102, and the outer surface of the melting tube 701 is fixedly connected to a passive gear 702.

[0048] It can be understood by those skilled in the art that the discarded plastic substrate in the 3D printing process is recycled, a heating plate is installed on the inner wall of the melting cylinder 701, and an automatic opening and closing door is provided at the right end of the melting cylinder 701. The discarded plastic substrate is put into the melting cylinder 701, and the heating plate melts the discarded plastic substrate. The output end of the transmission motor 703 drives the driving gear 704 to rotate, so that the driven gear 702 and the melting cylinder 701 rotate as a whole, so that the discarded plastic substrate is melted more fully.

[0049] Example 3

[0050] Please refer to Figure 4 As shown, the clamping mechanism 2 includes a first screw rod 201 and a first guide rod 202. The first screw rod 201 is rotatably connected to the inside of the frame 101, and the first guide rod 202 is fixedly installed in the inside of the frame 101. A first servo motor 203 is arranged on the outside of the frame 101. The first screw rod 201 is provided with a plurality of thread groups with opposite thread rotation directions, and both ends of each thread group are threadedly connected to a first movable plate 204, and a clamping block is fixedly connected to the first movable plate 204. One end of the first screw rod 201 is fixedly connected to the output end of the first servo motor 203, and a plurality of first movable plates 204 are slidably connected to the first guide rod 202.

[0051] Personnel in the technical field can understand that, by driving the first screw 201 to rotate through the output end of the first servo motor 203, the two groups of first movable plates 204 connected to the same thread group are moved closer to or farther away from each other, thereby the two groups of blocks fixedly connected to the two groups of first movable plates 204 are moved closer to or farther away from each other.

[0052] Example 4

[0053] Please refer to Figure 8-Figure 10As shown, the mold mechanism 3 includes a mold base 301, and second card slots 309 are provided on both sides of the mold base 301, and the second card slots 309 are adapted to the card blocks. The lower mold 302 is fixedly connected to the top of the mold base 301, and through slots 304 are provided on the lower mold 302 and the mold base 301. A sealing groove 303 is also provided at the bottom end of the lower mold 302. A lifting member 305 is slidably connected inside the through slot 304. A top plate 307 is fixedly connected to the top of the lifting member 305, and a bottom end of the top plate 307 is provided. A sealing ring matched with the sealing groove 303 is installed, and first card grooves 306 are opened on both sides of the outside of the lifting member 305. A fixed column 308 is fixedly connected to the middle of the bottom end of the lifting member 305, and electric push rods 310 are installed on both sides of the top of the mold base 301. The output end of the electric push rod 310 is fixedly installed with an upper mold 311, and the middle of the top of the upper mold 311 is provided with an injection port 312. A limit rod 313 is installed at the bottom of the mold base 301, and the lifting member 305 is slidably connected with the limit rod 313.

[0054] It can be understood by those skilled in the art that in real life, a factory produces more than one type of plastic product, so the inner cavity of the mold mechanism 3 in the present invention can be of the same type or of different types. The plastic base material liquid formed by the melting mechanism 7 can be used to produce plastic products well. The upper mold 311 and the lower mold 302 are connected by an electric push rod 310 to control the opening and closing of the mold mechanism 3. In the production of plastic products, the replacement and transfer of different mold mechanisms 3 are all performed by the grabbing mechanism 4, that is, the grabbing mechanism 4 grabs the external mold mechanism 3. And placed on the top of the frame 101, under the action of the first servo motor 203, the two groups of blocks are close to each other and respectively clamped in the second slots 309 to achieve the installation and fixation of the mold mechanism 3. In addition, a top plate 307 is also provided inside the mold mechanism 3. The top plate 307 is used to eject the plastic product after molding. Since the top plate 307 and the lower mold 302 are not fixedly connected, during the process of the grasping mechanism 4 grasping and transferring the mold mechanism 3, the lifting member 305 and the top plate 307 as a whole can easily fall off to the inside of the mold mechanism 3. Therefore, the present invention also provides a limiting rod 313 to limit the lifting member 305.

[0055] Example 5

[0056] Please refer to Figure 6As shown, the pull-down mechanism 5 includes an electric lifting rod 501 and a second movable plate 506. The electric lifting rod 501 is fixedly installed on the left side of the frame 101. The output end of the electric lifting rod 501 is fixedly connected to the connecting frame 502. The second screw rod 503 is rotatably connected inside the connecting frame 502. The threads at both ends of the second screw rod 503 are rotated in opposite directions. The second movable plate 506 is provided with two groups and is respectively threadedly connected to the two ends of the outer surface of the second screw rod 503. A third guide rod 504 is also welded inside the connecting frame 502. The second movable plate 506 is slidably connected to the third guide rod 504. The two groups of second movable plates 506 are fixedly connected to a clamping plate 507 on the side close to each other. The clamping plate 507 is adapted to the first clamping groove 306. One end of the second screw rod 503 is fixedly connected to the output end of the second servo motor 505. The second servo motor 505 is installed on the outside of the connecting frame 502.

[0057] Personnel in the technical field can understand that after the mold mechanism 3 is fixed by the clamping mechanism 2, the lifting member 305 is still sleeved on the limit rod 313, and the height of the two groups of second movable plates 506 and the card plate 507 is adjusted by extending and retracting the output end of the electric lifting rod 501, so that the height is adapted to the height of the first card slot 306, and the second screw 503 is driven to rotate by the output end of the second servo motor 505, so that the two groups of second movable plates 506 and the card plate 507 are close to each other as a whole, and the two groups of card plates 507 are respectively stuck in the inside of the first card slot 306 on both sides, and then the lifting member 305 is driven downward by the output end of the electric lifting rod 501, so that the top plate 307 moves downward, and the sealing ring at its bottom end is stuck in the sealing groove 303, thereby ensuring the sealing of the connection between the lower mold 302 and the top plate 307, and the melted plastic substrate liquid will not flow out of the mold mechanism 3.

[0058] Example 6

A limit plate 809 is installed on the top of the cylinder 805, and a through hole is opened on the limit plate 809 for the hose 808 to pass through.

[0060] It can be understood by those skilled in the art that the liquid base material liquid in the melting cylinder 701 is sucked through the liquid inlet pump 810, so that it enters the interior of the mold mechanism 3 through the liquid inlet pipe 811 and the hose 808; and the third screw rod 801 is driven to rotate by the output end of the third stepper motor 803, so that the movable part 804 slides back and forth along the outer surface of the fifth guide rod 802, so that the connector 807 can be moved to the top of the injection port 312 in each group of mold mechanisms 3, and then the connector 807 is driven downward by the output end of the cylinder 805, so that the connector 807 can be connected to each group of injection ports 312, and a sealing pad structure is also provided between the injection port 312 and the connector 807 to ensure the sealing of the connection; and the hose 808 is prevented from being entangled by providing a limit plate 809.

[0064] It is understood by those skilled in the art that, since the molding speeds of different plastic products are different during production, they cannot be ejected at the same time. In order to improve production efficiency, after the plastic products in a certain group of mold mechanisms 3 are molded, the second screw rod 601 is driven to rotate by the output end of the second stepping motor 603, so that the movable block 604 moves to the bottom of the mold mechanism 3, and then the mounting plate 606 is driven to move upward by the output end of the electric telescopic rod 605, so that the fixing column 308 is located inside the mounting plate 606, and then the driving gear 611 is driven by the output end of the driving motor 614. Rotation causes the outer gear 609, the rotating circle 607 and the inner gear 608 to rotate as a whole, and then all the driven gears 610 rotate synchronously, driving all the tooth plates 613 to move toward the center of the mounting plate 606, so that all the clamping members 612 also move toward the center of the mounting plate 606, clamping and fixing the fixed column 308, and finally the pull-down mechanism 5 releases the clamping of the lifting member 305, the mold mechanism 3 opens the mold, and the output end of the electric telescopic rod 605 continues to move upward, thereby driving the lifting member 305 to move upward, so that the top plate 307 ejects the molded plastic product.

[0065] Example 8

[0066] Please refer to Figure 2As shown, the grabbing mechanism 4 includes a fixed block 401, which is provided with two groups and are respectively welded to the front and rear sides of the top of the base plate 1, a second guide rod 403 is fixedly installed between the two groups of fixed blocks 401, a mechanical arm 405 is slidably connected to the second guide rod 403, the internal rotation of the two groups of fixed blocks 401 is connected to the first screw rod 402, the mechanical arm 405 is threadedly connected to the first screw rod 402, one group of fixed blocks 401 is fixedly connected to the outer side of the first stepper motor 404, and one end of the first screw rod 402 is fixedly connected to the output end of the first stepper motor 404.

[0067] It can be understood by those skilled in the art that the first screw 402 is driven to rotate by the output end of the first stepper motor 404, so that the robot arm 405 as a whole slides back and forth along the outer surface of the second guide rod 403, so that the robot arm 405 can move to the left side of each group of mold mechanisms 3, so as to facilitate the accurate placement of the mold mechanisms 3 at the installation position.

[0068] Example 9

[0069] Please refer to Figure 3 and Figure 4 As shown, the material guiding mechanism 9 includes a fourth screw rod 901 and a movable frame 904. The right side of the frame 101 is rotatably connected to the fourth screw rod 901, and the movable frame 904 is threadedly connected to the fourth screw rod 901. A sixth guide rod 902 is also fixedly installed on the right side of the frame 101, and the movable frame 904 is slidably connected to the sixth guide rod 902. One end of the fourth screw rod 901 is fixedly connected to the output end of the fourth stepper motor 903, and the fourth stepper motor 903 is fixedly installed on the outside of the frame 101. The inside of the movable frame 904 is rotatably connected to a material guiding frame 905, and a motor 906 for driving the fourth stepper motor 903 to rotate is arranged on the outside of the movable frame 904.

[0070] It can be understood by those skilled in the art that after the molded plastic product of the mold mechanism 3 is ejected by the top plate 307 at a certain point, the fourth screw 901 is driven to rotate by the output end of the fourth stepper motor 903, so that the movable frame 904 moves to the right side of the molded plastic product, and the guide frame 905 is driven to rotate close to the lower mold 302 by the output end of the motor 906, and the robotic arm 405 pushes the molded plastic product into the guide frame 905, slides it onto the conveyor 105, and transmits it to the next process.

[0071] Working principle and use process of this device: In real life, factories do not only produce one kind of plastic products. The inner cavity of the mold mechanism 3 in the present invention can be of the same type or of different types. The plastic base material liquid formed by the melting mechanism 7 can be well used to produce plastic products, so that resources are effectively and fully utilized. According to the production needs in the factory, the type of mold mechanism 3 is determined, and the mechanical arm 405 grabs the external mold mechanism 3. Under the action of the output end of the first stepper motor 404, the mechanical arm 405 moves to the installation position of each mold mechanism 3 in turn, and places the determined mold mechanism 3 on the top of the frame 101. The output end of the first servo motor 203 drives the first screw 201 to rotate, so that the two groups of first movable plates 204 connected to the same thread group are close to each other, and the two groups of clamping plates 507 are respectively clamped in the inside of the first clamping grooves 306 on both sides, so that all mold mechanisms 3 are installed;

[0072] Since the mold mechanism 3 is clamped by the clamping mechanism 2, the lifting member 305 is still sleeved on the limit rod 313. The output end of the electric lifting rod 501 is extended and retracted to adjust the height of the two groups of second movable plates 506 and the card plate 507 so that the height is adapted to the height of the first card slot 306. The output end of the second servo motor 505 drives the second screw 503 to rotate so that the two groups of second movable plates 506 and the card plate 507 are closer to each other as a whole. The two groups of card plates 507 are respectively stuck in the inside of the first card slots 306 on both sides. Then, the lifting member 305 is driven downward by the output end of the electric lifting rod 501 to move the top plate 307 downward. The sealing ring at the bottom end is stuck in the sealing groove 303, thereby ensuring the sealing of the connection between the lower mold 302 and the top plate 307, and the melted plastic substrate liquid will not flow out of the mold mechanism 3.

[0073] Then, the melting mechanism 7 melts the waste plastic substrate collected in the factory into liquid, and the liquid is added to the mold mechanism 3 through the feeding mechanism 8. Since the molding speeds of different plastic products are different during production, they cannot be ejected at the same time. In order to improve production efficiency, after the plastic products in a certain group of mold mechanisms 3 are formed, the second screw 601 is driven to rotate through the output end of the second stepper motor 603, so that the movable block 604 moves to the bottom of the mold mechanism 3, and then the mounting plate 606 is driven to move upward through the output end of the electric telescopic rod 605, so that the fixed column 308 is located inside the mounting plate 606, and then the driving gear 611 is driven to rotate through the output end of the driving motor 614, so that the outer gear 609, the rotating circle 607 and the inner gear 608 rotate as a whole, and then all the driven gears 610 rotate synchronously, driving all the tooth plates 613 to move toward the center of the mounting plate 606. , so that all the clamping members 612 also move toward the center of the mounting plate 606, clamp and fix the fixing column 308, and finally the two groups of clamping plates 507 release the clamping of the lifting member 305, and the mold mechanism 3 opens the mold, and the output end of the electric telescopic rod 605 continues to move upward, thereby driving the lifting member 305 to move upward, so that the top plate 307 ejects the molded plastic product, and the output end of the fourth stepper motor 903 drives the fourth screw rod 901 to rotate, so that the movable frame 904 moves to the right side of the molded plastic product, and the output end of the motor 906 drives the guide frame 905 to rotate close to the lower mold 302, and the robot arm 405 pushes the molded plastic product into the guide frame 905, and slides it onto the conveyor 105, and transmits it to the next process, and the mold mechanism 3 continues to close the mold and continue to inject liquid. Through this processing method, the production efficiency of plastic products is accelerated and the needs of the staff are met.
