One side of the raw material box 7 is connected to a feeding pipe 30, and one end of the feeding pipe 30 is connected to the inner cavity of the mold 49.

[0024] A gear 40 is rotatably provided on one side of the workbench 5, and the gear 40 is meshed with the tooth block on the outer ring of the turntable 6. A motor 7 39 is fixedly connected to one side of the workbench 5, and the output end of the motor 7 39 is fixedly connected to the gear 40.

[0025] A motor 6 28 is fixedly connected to one side of the upper end surface of the mold 49 , a threaded rod 3 29 is fixedly connected to the output end of the motor 6 28 , and the threaded rod 3 29 is threadedly connected to one side of the cover plate 27 .

[0026] Two sliding rods 33 are fixedly connected to one side of the push plate 31, and the sliding rods 33 are slidably connected to the mold 49. One end of the sliding rod 33 is fixedly connected to the connecting block 32. A fixed plate 35 is fixedly connected to one side of the workbench 5.

[0027] Specifically, in the initial state, the cover plate 27 covers the inner cavity of the mold 49, and the push plate 31 is at the edge of the inner cavity of the mold 49. At this time, the cover plate 27, the push plate 31, and the mold 49 form a complete molding cavity, and the molding cavity is a cube, and the molded plastic product is also a cube.

[0030] The clamping plate 17 is also provided with an adjustable detection mechanism for judging whether the end faces of the multiple plastic products on the receiving plate 18 are in contact with each other; The adjustable detection mechanism includes a slider 20 slidably connected to one side of a splint 17, an infrared transmitter 48 is arranged on one side of the slider 20, a threaded rod 19 is threadedly connected to one side of the slider 20, both ends of the threaded rod 19 are rotatably arranged on the splint 17, one end of the splint 17 is fixedly connected to a motor 4 21, and the output end of the motor 4 21 is fixedly connected to one end of the threaded rod 19.

[0031] The second clamping plate 22 is also provided with a sliding push corner assembly that can make the multiple plastic products on the receiving plate 18 face in the same direction; The sliding push angle assembly includes a slider 2 43 slidably connected to one side of the splint 22, one side of the slider 2 43 is plugged and slidably connected with a push angle plate 47, one side of the splint 22 is provided with a groove 41, the splint 22 can pass through the groove and contact the plastic product, one side of the slider 2 43 is threadedly connected with a threaded rod 26, both ends of the threaded rod 26 are rotatably set on the splint 22, one end of the splint 22 is fixedly connected with a motor 8 42, the output end of the motor 8 42 is fixedly connected to one end of the threaded rod 26, one side of the slider 2 43 is rotatably provided with a connecting rod 2 45, one end of the connecting rod 2 45 is rotatably provided with a connecting rod 3 46, one end of the connecting rod 3 46 is rotatably connected to one side of the push angle plate 47, one side of the slider 2 43 is fixedly connected with a motor 9 44, and the output end of the motor 9 44 is fixedly connected to one end of the connecting rod 2 45.

[0032] The receiving plate 18 is also provided with a conveying assembly; The conveying assembly includes rotating rollers 24 rotatably arranged on both sides of the receiving plate 18, and a conveying belt 25 is arranged on the rotating rollers 24. A motor 5 23 is fixedly connected to one side of the receiving plate 18, and an output end of the motor 5 23 is fixedly connected to the rotating rollers 24.

[0033] Specifically, in the prior art, after the plastic product is formed, although the ejection structure can be used to demold the plastic product, in some cases, in order to improve the molding efficiency, plastic raw materials of different colors are injected into multiple molds 49 of the same specifications at one time to achieve the purpose of molding multiple plastic products of different colors at the same time, and in order to facilitate the subsequent packaging of the multiple molded plastic products, the multiple molded plastic products need to be arranged and placed in a fixed order, and then transported to the packaging process for packaging through a conveying mechanism. After the plastic products are demolded by the ejection structure, the plastic products of different colors need to be manually sorted and placed on the conveying mechanism. The whole process is relatively cumbersome and prone to sorting errors. Therefore, in order to solve the above problems, when the present embodiment is used, the bottom plate 1 is placed next to the conveying mechanism for conveying the arranged plastic products, and then different colors of injection molding materials are added to different raw material boxes 7 respectively, and the injection molding materials of different colors enter different molds 49 at the same time. When the injection molding materials in all molds 49 are cooled and formed, the turntable 6 is driven to rotate. Whenever a mold 49 is aligned with the receiving plate 18, the cover plate 27 is driven to move upward, and then the push plate 31 is driven to move to push out the molded plastic products. The plastic products are moved to the receiving plate 18 and slide down with the receiving plate 18. By controlling the rotation of the turntable 6, multiple plastic products can be arranged in a preset order. The plastic products are placed on the receiving plate 18. After the arrangement is completed, the motor 3 14 drives the bidirectional threaded rod 15 to rotate, so that the clamping plate 17 and the clamping plate 2 22 are close to each other to clamp the multiple plastic products on the receiving plate 18. Then the motor 13 drives the connecting rod 12 to rotate, so that the displacement plate 4 moves until the displacement plate 4 is above the conveying mechanism, and the multiple plastic products are also above the conveying mechanism. Then the motor 2 12 drives the adjustment plate 13 to rotate, so that the bottom of the multiple plastic products is parallel to the top of the conveying mechanism, and then the electric push rod 1 9 drives the lifting block 11 to descend, so that the plastic products are accurately placed at the specified position of the conveying mechanism, and then the clamping plate 17 and the clamping plate 2 22 are driven to loosen the plastic products. The plastic products follow the conveying mechanism to enter the next process for packaging, so that after a plurality of plastic products of different colors are formed, they can be arranged and placed in a preset order, and can be uniformly transferred to the conveying mechanism after arrangement, and the conveying mechanism brings the plastic products to the packaging process for packaging, thereby eliminating the process of workers manually arranging the plastic products after demoulding, which is more labor-saving, is conducive to improving the subsequent packaging efficiency of plastic products, and also avoids the situation of sorting errors caused by manual sorting; Although the above method can realize automatic sorting of multiple plastic products, since each plastic product after demoulding slides along the receiving plate 18, when the friction between the plastic product and the receiving plate 18 is large, the plastic product may get stuck during the sliding process, resulting in failure to fall normally, and there will be gaps between the plastic products, which not only cannot reasonably utilize the placement space of the receiving plate 18, but also causes gaps between the plastic products transferred to the conveying mechanism, affecting the subsequent packaging efficiency. Therefore, in order to avoid this situation, after the plastic product is pushed onto the receiving plate 18, the motor 5 23 drives the rotating roller 2 on one side. 4 rotates, and under the action of the rotating roller 24 on the other side, the conveyor belt 25 is operated, and the conveyor belt 25 can drive the plastic products to move until the plastic products are attached to each other, and the plastic products that have been attached to each other will not move under the action of the conveyor belt 25, thereby avoiding the situation that when the plastic products move to the receiving plate 18, the friction between the plastic products and the receiving plate 18 is large, causing the plastic products to get stuck during the sliding process and cannot slide down normally. Not only the placement space of the receiving plate 18 is reasonably utilized, but also after the plastic products are transferred to the conveying mechanism, the adjacent plastic products are also closely attached, which is conducive to improving the subsequent packaging efficiency of the plastic products; Although the above method can make the adjacent plastic products on the receiving plate 18 fit tightly, since the plastic products are cubes, when the plastic products slide onto the receiving plate 18, the adjacent plastic products may not fit together at the end faces, but at the edges and ends. This will not only cause the first clamp 17 and the second clamp 22 to fit the edges and corners of the plastic products, but also cause the subsequent packaging to be affected due to the different orientations of the plastic products. Therefore, in order to avoid this problem, after a batch of plastic products are arranged on the receiving plate 18, the plastic products on the receiving plate 18 are arranged in a certain direction. The total number of products can be obtained to obtain the standard length when the end faces of multiple plastic products are fitted together. If the end faces of two adjacent plastic products are not fitted together, the standard length will increase because the diagonal length of a square is greater than the side length. Therefore, according to the standard length when the end faces of multiple plastic products are fitted together, the motor 21 drives the threaded rod 19 to rotate, so that the slider 20 slides on the clamping plate 17 until the distance between the emitting end of the infrared transmitter 48 and the end face of the lowermost plastic product exceeds the standard length and is within a reasonable range. At this time, the infrared transmitter 48 emits infrared rays. If no plastic products are detected, it means that the end faces of the plastic products are fitted together. If it is detected If the length of the plurality of plastic products exceeds the standard length, the motor 8 42 drives the threaded rod 26 to rotate, so that the slider 2 43 slides on the clamping plate 22, and the angle push plate 47 starts to move from the starting position of the standard length. Whenever the angle push plate 47 moves the length of a plastic product side, the slider 2 43 stops moving, and the motor 9 44 drives the connecting rod 2 45 and the connecting rod 3 46 to rotate, so that the angle push plate 47 slides on the slider 2 43 and passes through the groove 41 to contact the plastic product. If the end faces of two adjacent plastic products are not in contact, the plastic product will be deflected due to the corners being pushed. When the angle push plate 47 moves to the end of the clamping plate 22, at this time, the red If the external transmitter 48 can still detect plastic products, it still means that the end faces of adjacent plastic products are not fitted together, and then the angle plate 47 is pushed to repeat the work until the infrared transmitter 48 can no longer detect plastic products. At this time, the end faces of adjacent plastic products on the receiving plate 18 are all in a fitted state, and then the plastic products can be transferred using the clamping plate 17 and the clamping plate 22, thereby avoiding the situation where when the plastic products slide onto the receiving plate 18, the edges and corners of the adjacent plastic products fit together with the end faces, resulting in the inability of the clamping plates 17 and 22 to clamp the plastic products normally. In addition, the multiple plastic products have the same orientation, which is conducive to subsequent unified packaging.

[0034] Working principle: In the initial state, the cover plate 27 covers the inner cavity of the mold 49, and the push plate 31 is at the edge of the inner cavity of the mold 49. At this time, the cover plate 27, the push plate 31, and the mold 49 form a complete molding cavity, and the molding cavity is a cube, and the molded plastic product is also a cube. Then the raw material box 7 transports the injection molding raw material to the molding cavity through the feeding pipe 30. When the raw material is cooled and molded in the molding cavity, the motor 6 28 drives the threaded rod 3 29 to rotate to make the cover plate 27 rise, so that the molded plastic product is no longer covered. At this time, the motor 7 39 can drive the gear 40 to rotate. The turntable 6 is rotated in a moving manner until the connecting block 32 is aligned with the push block 38, and the push block 38 is driven to move by the electric push rod 2 36, so that the push block 38 squeezes the connecting block 32, so that the slide bar 33 and the push plate 31 can be moved at the same time. When the push plate 31 moves in the inner cavity of the mold 49, the molded plastic product can be pushed out, thereby realizing the automatic demoulding of the molded plastic product, which is more convenient. The bottom plate 1 is placed next to the conveying mechanism for conveying the arranged plastic products, and then different colors of injection molding materials are added to different raw material boxes 7 respectively, and the injection molding materials of different colors are At the same time, the plastic products enter different molds 49. When the injection molding materials in all the molds 49 are cooled and formed, the turntable 6 is driven to rotate. When a mold 49 is aligned with the receiving plate 18, the cover plate 27 is driven to move upward, and then the push plate 31 is driven to move to push out the formed plastic products. The plastic products are moved to the receiving plate 18 and slide down with the receiving plate 18. By controlling the rotation of the turntable 6, multiple plastic products can be arranged and placed on the receiving plate 18 in a preset order. After the arrangement is completed, the motor 3 14 drives the bidirectional threaded rod 15 to rotate, so that the clamping plate 1 7 and the second clamping plate 22 are close to each other to clamp the multiple plastic products on the receiving plate 18, and then the motor 13 drives the connecting rod 12 to rotate, so that the displacement plate 4 moves until the displacement plate 4 is above the conveying mechanism, and the multiple plastic products are also above the conveying mechanism, and then the motor 12 is used to drive the adjustment plate 13 to rotate, so that the bottoms of the multiple plastic products are kept parallel to the top of the conveying mechanism, and then the electric push rod 19 is used to drive the lifting block 11 to descend, so that the plastic products are accurately placed at the specified position of the conveying mechanism, and then the clamping plate 17 and the second clamping plate 22 are driven to loosen the plastic products, so that the plastic products follow the conveying mechanism to enter the next process for packaging, so that after the multiple plastic products of different colors are formed, they can be arranged and placed in a preset order, and can be uniformly transferred to the conveying mechanism after arrangement, and the conveying mechanism brings the plastic products into the packaging process for packaging, thereby eliminating the process of workers manually arranging the demoulding plastic products, which is more labor-saving, is conducive to improving the subsequent packaging efficiency of plastic products, and also avoids the situation of sorting errors due to manual sorting;Although the above method can realize automatic sorting of multiple plastic products, since each plastic product after demoulding slides along the receiving plate 18, when the friction between the plastic product and the receiving plate 18 is large, the plastic product may get stuck during the sliding process, resulting in failure to fall normally, and there will be gaps between the plastic products, which not only cannot reasonably utilize the placement space of the receiving plate 18, but also causes gaps between the plastic products transferred to the conveying mechanism, affecting the subsequent packaging efficiency. Therefore, in order to avoid this situation, after the plastic product is pushed onto the receiving plate 18, the motor 5 23 drives the rotating roller 2 on one side. 4 rotates, and under the action of the rotating roller 24 on the other side, the conveyor belt 25 is operated, and the conveyor belt 25 can drive the plastic products to move until the plastic products are attached to each other, and the plastic products that have been attached to each other will not move under the action of the conveyor belt 25, thereby avoiding the situation that when the plastic products move to the receiving plate 18, the friction between the plastic products and the receiving plate 18 is large, causing the plastic products to get stuck during the sliding process and cannot slide down normally. Not only the placement space of the receiving plate 18 is reasonably utilized, but also after the plastic products are transferred to the conveying mechanism, the adjacent plastic products are also closely attached, which is conducive to improving the subsequent packaging efficiency of the plastic products;Although the above method can make the adjacent plastic products on the receiving plate 18 fit tightly, since the plastic products are cubes, when the plastic products slide onto the receiving plate 18, the adjacent plastic products may not fit together at the end faces, but at the edges and ends. This will not only cause the first clamp 17 and the second clamp 22 to fit the edges and corners of the plastic products, but also cause the subsequent packaging to be affected due to the different orientations of the plastic products. Therefore, in order to avoid this problem, after a batch of plastic products are arranged on the receiving plate 18, the plastic products on the receiving plate 18 are arranged in a certain direction. The total number of products can be obtained to obtain the standard length when the end faces of multiple plastic products are fitted together. If the end faces of two adjacent plastic products are not fitted together, the standard length will increase because the diagonal length of a square is greater than the side length. Therefore, according to the standard length when the end faces of multiple plastic products are fitted together, the motor 21 drives the threaded rod 19 to rotate, so that the slider 20 slides on the clamping plate 17 until the distance between the emitting end of the infrared transmitter 48 and the end face of the lowermost plastic product exceeds the standard length and is within a reasonable range. At this time, the infrared transmitter 48 emits infrared rays. If no plastic products are detected, it means that the end faces of the plastic products are fitted together. If it is detected If the length of the plurality of plastic products exceeds the standard length, the motor 8 42 drives the threaded rod 26 to rotate, so that the slider 2 43 slides on the clamping plate 22, and the angle push plate 47 starts to move from the starting position of the standard length. Whenever the angle push plate 47 moves the length of a plastic product side, the slider 2 43 stops moving, and the motor 9 44 drives the connecting rod 2 45 and the connecting rod 3 46 to rotate, so that the angle push plate 47 slides on the slider 2 43 and passes through the groove 41 to contact the plastic product. If the end faces of two adjacent plastic products are not in contact, the plastic product will be deflected due to the corners being pushed. When the angle push plate 47 moves to the end of the clamping plate 22, at this time, the red If the infrared transmitter 48 still detects plastic products, it still means that the end faces of adjacent plastic products are not attached. Then the angle plate 47 is pushed to repeat the work until the infrared transmitter 48 cannot detect plastic products. At this time, the end faces of adjacent plastic products on the receiving plate 18 are all in a state of attachment. Then the clamping plate 17 and the clamping plate 22 can be used to transfer the plastic products, thereby avoiding the situation that when the plastic products slide onto the receiving plate 18, the adjacent plastic products are attached to the corners and end faces, resulting in the clamping plate 17 and the clamping plate 22 being unable to normally clamp multiple plastic products when clamping the plastic products. In addition, multiple plastic products are oriented in the same direction, which is conducive to subsequent unified packaging. ;
