Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and in particular to an injection molding device and its injection molding process. Background Technology

[0002] Injection molding, also known as injection stamping, is a method of producing molded parts by injecting fully molten plastic material, stirred by a screw at a specific temperature, into a mold cavity under high pressure, and then allowing it to cool and solidify. This method is suitable for the mass production of complex-shaped parts and is one of the important processing methods. Injection molding typically involves steps such as mold closing, injection, pressure holding, cooling, mold opening, and product assembly. During the injection molding process, the injection molding machine generates waste material, which is usually processed and reused as injection molding material.

[0003] Currently, workers manually collect the waste generated during the injection molding process, then shred it using a shredder, and finally pour the shredded waste into a feeding hopper. After being picked up by a suction machine, the waste is returned to the injection molding machine for reprocessing.

[0004] When sucking up shredded waste from the feeding box, the staff holds the suction head of the suction machine and sucks it up according to the height of the waste in the feeding box. The staff needs to observe and operate it at all times, which wastes a lot of the staff’s time and is an area that needs to be improved. Summary of the Invention

[0005] In order to better absorb waste materials, make injection molding equipment more automated, and save workers a lot of time, this application provides an injection molding equipment and its injection molding process.

[0006] This application provides an injection molding equipment and injection molding process, which adopts the following technical solution:

[0007] An injection molding machine includes an injection molding apparatus and further includes...

[0008] A conveyor belt is mounted on the injection molding device;

[0009] A cutting device located below the conveyor belt, the cutting device being used to cut waste material;

[0010] A feeding box, located below the discharge port of the cutting device;

[0011] A material suction device that sucks waste material from the loading box into the injection molding device;

[0012] The material suction block is hollow, and several suction holes are opened through the side wall of the material suction block. The suction holes are all located near the bottom wall of the feeding box.

[0013] A pusher plate, which is slidably connected to the feeding box, slides toward the suction block;

[0014] A drive assembly is disposed on the feeding box and is used to drive the pusher plate to slide.

[0015] By adopting the above technical solution, the waste generated by the injection molding unit falls onto the conveyor belt, which transports the waste to the top of the cutting device. The waste falls into the cutting device, which cuts the waste. After cutting, the waste enters the feeding box. The suction block of the suction device is connected to the suction block. The suction device picks up the waste, which is sucked into the suction block and then transferred to the injection molding unit. During the suction process, the drive component is activated, which drives the pusher plate to slide, pushing the waste in the feeding box to a position close to the suction block, so that the suction block comes into contact with the waste. This reduces the possibility that the suction block will not pick up the waste, and eliminates the need for operators to support the suction head of the suction device for a long time, thus improving the automation level of the injection molding equipment.

[0016] Optionally, the drive assembly includes a drive frame that slides on the loading box and a drive rod that slides on the loading box. The drive rod is fixedly connected to the drive frame. The pusher plate is slidably connected to the drive frame. A lead screw is threaded onto the pusher plate. A gear is coaxially fixed to the end of the lead screw. A rack is fixed to the inner wall of the loading box. The gear can mesh with the rack. The rack is located at one end of the loading box. The gear has a pawl. The loading box is provided with a power component for driving the drive rod to slide.

[0017] By adopting the above technical solution, during the process of the suction device absorbing shredded waste, the power component is activated, which drives the drive rod to slide, the drive rod drives the drive frame to slide, and the drive frame drives the pusher plate to slide towards the suction block. The pusher plate pushes some of the waste to move, transporting the waste to a position close to the suction block for easy absorption. After one waste push is completed, the drive rod drives the drive frame to move away from the suction block. When the gear and rack are engaged, the end of the pawl slides on the gear, at which point the gear idles. When the drive rod slides towards the suction block again, the gear and rack mesh, and the pawl abuts against the gear, causing the gear to drive the lead screw to rotate together. The pusher plate slides a distance along the height direction of the drive frame, thus facilitating the pushing of waste in the feeding box.

[0018] Optionally, a rotating disk is fixed on the lead screw, and the rotating disk is located on the side of the gear opposite to the lead screw.

[0019] By adopting the above technical solution, after the waste material in the feeding box is sucked up, the operator turns the rotating disc, which drives the lead screw to rotate and causes the pusher plate to slide away from the bottom wall of the feeding box, making it easier to push the waste material in the feeding box next time.

[0020] Optionally, the discharge port of the suction device is connected to a discharge pipe, and the discharge port of the discharge pipe is connected to two feed pipes. A guide plate is hinged to the inner wall of the discharge pipe, and the guide plate is used to block the discharge pipe. One of the discharge pipes is connected to a mixing chamber at its discharge port, and the discharge port of the other discharge pipe is connected to the feed port of the injection molding device. The discharge port of the mixing chamber is connected to the feed port of the injection molding device. A driving component is provided on the discharge pipe to drive the guide plate to rotate.

[0021] By adopting the above technical solution, the waste material sucked up by the suction device enters the feed pipe through the discharge pipe, and the feed pipe supplies the waste material to the injection molding device. When the product color requirement is black, the drive unit is activated, which drives the guide plate to rotate. The guide plate blocks the inlet of the feed pipe corresponding to the mixing chamber, and the color powder is heated and mixed. When the product color requirement is not black, the drive unit is activated, which drives the guide plate to rotate. The guide plate blocks the inlet of the feed pipe away from the mixing chamber. At this time, the waste material is sucked into the mixing chamber, and the raw material mixed with pigment is poured into the mixing chamber for mixing. The mixed injection molding material is then poured into the injection molding device for injection molding, thus facilitating the production of products with different color requirements.

[0022] Optionally, a window slidably connected to the side wall of the mixing chamber, the window being transparent.

[0023] By adopting the above technical solution, the staff can pull the window sash to put the pigment into the mixing chamber and observe the mixing of the raw materials and pigments in the mixing chamber through the window sash, which provides convenience for the staff to observe the mixing of materials in the mixing chamber.

[0024] Optionally, a snap-fit ​​groove is provided on the side wall of the suction block, and the feed inlet of the suction device is located in the snap-fit ​​groove.

[0025] By adopting the above technical solution, the staff inserts the suction end of the suction device into the snap-fit ​​groove. After the waste enters the suction block, it is directly sucked into the inner cavity of the suction device, reducing the collision between the waste and the end of the pipe, making the connection between the suction device and the suction block more convenient.

[0026] Optionally, a magnetic block is fixed on the side wall of the suction block, and the inner wall of the feeding box is magnetically set, so that the suction block is adsorbed onto the inner wall of the feeding box.

[0027] By adopting the above technical solution, before loading the waste material after cutting into the feeding box, the suction block is moved to different positions on the inner wall of the feeding box. The operator only needs to remove the suction block and attach it to different positions on the inner wall of the feeding box, which makes it easier to fix the suction block and to pick up waste material from different positions in the feeding box.

[0028] Optionally, the raw material is supplied by placing it on the conveyor belt, which transports it to the cutting device, and the cut raw material enters the feeding box.

[0029] The raw material is picked up by connecting the suction port of the suction device to the suction block, and the suction device transfers the raw material into the injection molding unit.

[0030] The raw material is pushed by the power component, which drives the drive rod to slide, the drive rod drives the drive frame to slide, and the drive frame drives the pusher plate to slide, transporting the waste material to a position close to the suction block;

[0031] Waste disposal: Waste generated during the injection molding process by the injection molding device falls onto the conveyor belt, and the waste is transported to the cutting device for chopping and then poured into the feeding box.

[0032] Waste material utilization: The suction device picks up the waste material from the feeding box and sends it into the injection molding device.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. During the injection molding process, the waste material generated by the injection molding unit falls onto the conveyor belt. The conveyor belt transports the waste material to the cutting device, which cuts the waste material. The cut waste material enters the feeding box from the outlet of the cutting device. Under the suction of the suction device, the waste material passes through the suction block and enters the suction device. The suction device delivers the waste material to the injection molding unit for injection molding. During the process of suctioning the waste material, the drive component of the suction device drives the pusher plate to slide. The pusher plate pushes the waste material in the feeding box towards the suction block, making it easier for the suction block to pick up the waste material in the feeding box.

[0035] 2. As the power component drives the drive rod to slide towards the suction block, it drives the drive frame to slide, which in turn drives the pusher plate to slide, pushing the waste material in the loading box towards the suction block. At the beginning of the drive rod's sliding motion, the gear and rack mesh, causing the lead screw to rotate, which makes the pusher plate tend to slide downwards, making it easier to push away more waste material. When the drive rod retracts, the pawl slides when the gear and rack mesh, and the lead screw is stationary, preventing the pusher plate from retracting again.

[0036] 3. When producing black products, the guide plate blocks the corresponding feed pipe of the mixing chamber, allowing waste material to enter the injection molding device from another feed pipe. During this process, only heating and pigment mixing are required. When producing products that do not require black, the guide plate blocks the feed pipe of the original mixing chamber, allowing waste material to enter the mixing chamber. The operator adds the pigment to the mixing chamber and mixes it. After the raw materials and pigment are evenly mixed, they are fed into the injection molding device, making it easier to produce products of different colors. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0045] This application discloses an injection molding equipment and its injection molding process.

[0046] Reference Figure 1An injection molding machine includes an injection molding device 1, a cutting device 3, and a material suction device 5. The injection molding device 1 is used for product processing. The cutting device 3 is used to cut the waste material generated by the injection molding device 1. The material suction device 5 is used to pick up the shredded waste material and resupply the picked-up waste material to the injection molding device 1. The injection molding device 1 reuses the cut waste material to inject products.

[0047] Reference Figure 1 A conveyor belt 2 is wound around the side wall of the injection molding device 1 via a rotating shaft. The conveyor belt 2 is located below the waste outlet of the injection molding device 1. The waste generated by the injection molding device 1 during the injection process falls through the waste outlet onto the upper surface of the conveyor belt 2 for easy transport by the transmission belt.

[0048] Reference Figure 1 The injection molding equipment also includes a feeding box 4, which is located below the discharge port of the cutting device 3. The waste material falling into the cutting device 3 is cut and then falls into the feeding box 4. The feeding box 4 is designed to hold the waste material after cutting. The end of the suction tube of the suction device 5 is located in the feeding box 4, and the waste material in the feeding box 4 is transferred to the injection molding unit 1 for reuse.

[0049] Reference Figure 2 and Figure 3 The inner wall of the feeding box 4 is equipped with a suction block 6, which is set along the height of the feeding box 4. A fixing groove is opened on the side wall of the suction block 6, and a magnetic block 23 is fixed on the inner wall of the fixing groove. The inner side wall of the feeding box 4 is magnetically set. The operator attaches the suction block 6 to the inner wall of the feeding box 4. Before loading waste into the feeding box 4, the operator fixes the suction block 6 at different positions on the inner wall of the feeding box 4 as needed.

[0050] Reference Figure 2 and Figure 3 In this application, the suction block 6 is preferably hollow. Several suction holes 7 are provided on the side wall of the suction block 6. The suction holes 7 are all connected to the inner cavity of the suction block 6. The suction holes 7 are all located at one end of the suction block 6 near the bottom wall of the feeding box 4. A snap-fit ​​groove 22 is provided at the end of the suction block 6 away from the suction holes 7. In this application, the snap-fit ​​groove 22 is coaxially arranged with the inner cavity of the snap-fit ​​block. The operator inserts the suction port of the suction device 5 into the snap-fit ​​groove 22 to fix the suction head of the suction device 5 to the suction block 6. The snap-fit ​​groove 22 facilitates the fixing of the suction head of the suction device 5 to the suction block 6. The suction device 5 sucks up the waste material in the feeding box 4 through the suction block 6.

[0051] Reference Figure 2A pusher plate 8 slides inside the inner cavity of the feeding box 4. The pusher plate 8 is set to push the waste material in the feeding box 4 to a position close to the suction block 6. The feeding box 4 is provided with a drive component 9 for driving the pusher plate 8 to slide. During the suction process, the drive component 9 intermittently drives the pusher plate 8 to slide towards the suction block 6, so as to facilitate the suction device 5 to pick up the waste material.

[0052] Reference Figure 2 and Figure 4 The drive assembly 9 includes a drive frame 91 that slides along the length of the feed box 4 and a drive rod 92 that slides along the length of the feed box 4. The drive rod 92 is fixedly connected to the drive frame 91 by screws. A gear 11 is rotatably connected to the drive frame 91 via a rotating shaft. A lead screw 10 is rotatably connected to the side wall of the gear 11. The push plate 8 is threadedly connected to the lead screw 10. A pawl 13 with a torsion spring is hinged to the outer wall of the lead screw 10. Several limiting grooves are provided on the side wall of the gear 11. The end portion of the pawl 13... Within the limiting groove; a rack 12 is fixed to the inner wall of the feeding box 4 by screws. The rack 12 is located at the end of the feeding box 4. A power component 14 for driving the drive rod 92 to slide is provided on the side wall of the feeding box 4. In this application, the power component 14 is preferably an electric cylinder. The piston rod of the power component 14 is fixedly connected to the drive rod 92 by a connecting rod. When the power component 14 is turned on, the piston rod of the power component 14 slides, driving the drive rod 92 to slide. The drive rod 92 drives the drive frame 91 to slide, thereby driving the push plate 8 to slide.

[0053] Reference Figure 2 and Figure 4 The initial position of the drive rod 92 is close to the rack 12. During the sliding process of the drive rod 92 driven by the power component 14, the drive frame 91 is also driven to slide. The drive frame 91 drives the gear 11 to move. The gear 11 meshes with the rack 12. At this time, the end of the pawl 13 abuts against the inner wall of the limiting groove. The gear 11 drives the lead screw 10 to rotate synchronously. The pusher plate 8 slides a distance towards the bottom wall of the upper material box 4, which facilitates the pusher plate 8 to push the waste material to move. When the power component 14 drives the drive rod 92 to retract the gear 11 and mesh with the rack 12, the pawl 13 slides on the inner wall of the limiting groove. At this time, the gear 11 rotates and the lead screw 10 is stationary, preventing the pusher plate 8 from sliding away from the bottom wall of the upper material box 4.

[0054] Reference Figure 4 A rotating disk 15 is coaxially fixed to the end of the lead screw 10. The rotating disk 15 is located on the side of the drive frame 91 away from the lead screw 10. After the waste material is pushed, the rotating disk 15 is manually turned. The rotating disk 15 drives the lead screw 10 to rotate, so that the pusher plate 8 slides on the outer wall of the lead screw 10. The pusher plate 8 slides away from the bottom wall of the feeding box 4, reducing the impact on the waste material loaded into the feeding box 4, and making it easier to push the waste material in the feeding box 4 to move again.

[0055] Reference Figure 2 and Figure 5 The discharge port of the suction device 5 is connected to a discharge pipe 16, and two feed pipes 17 are connected to the discharge port of the discharge pipe 16. The waste material sucked by the suction device 5 enters the feed pipe 17 through the discharge pipe 16. The feed pipe 17 is set to load waste material into the injection molding equipment. A guide plate 18 is rotatably connected to the inner wall of the discharge pipe 16. The guide plate 18 is set to block the feed pipe 17, so that the waste material sucked by the suction device 5 each time passes through one of the feed pipes 17.

[0056] Reference Figure 5 The discharge pipe 16 is provided with a drive component 20 for driving the guide plate 18 to rotate. In this application, the drive component 20 is preferably a drive cylinder. The rotating shaft of the drive component 20 is fixedly connected to the side wall of the guide plate 18 through a connecting rod. When the drive component 20 is started, the rotating shaft of the drive component 20 rotates, thereby driving the guide plate 18 to rotate. The guide plate 18 is located near the inlet of the two feed pipes 17.

[0057] Reference Figure 1 and Figure 2 One of the feed pipes 17 is equipped with a mixing chamber 19. The outlet of the feed pipe 17 corresponding to the mixing chamber 19 is connected to the inlet of the mixing chamber 19. The outlet of the mixing chamber 19 is connected to the inlet of the injection molding device 1 through a conduit. The mixing chamber 19 is designed to facilitate the mixing of incoming waste materials. When only black products are produced, the drive unit 20 drives the guide plate 18 to block the feed pipe 17 corresponding to the mixing chamber 19. If there are other colors on the waste materials, they can be mixed by heating the color powder. If the product color requirement is not black, the guide plate 18 blocks the feed pipe 17 away from the mixing chamber 19, allowing the waste materials to enter the mixing chamber 19. The operator adds the color powder into the mixing chamber 19, and the mixing chamber 19 mixes the raw materials and color powder inside. The mixture is then fed into the injection molding device 1 through the feed pipe 17, thus facilitating the production of products of different colors.

[0058] Reference Figure 1 and Figure 2 A window sash 21 is slidably connected to the side wall of the mixing chamber 19. The window sash 21 slides along the circumference of the mixing chamber 19. In this application, the window sash 21 is preferably made of transparent material. The operator puts color powder into the mixing chamber 19 by opening the window sash 21. Under the stirring of the mixing chamber 19, the color powder and waste material in the mixing chamber 19 are fully mixed. The mixed raw material color powder enters the injection molding device 1 through the feeding pipe 17, which is convenient for producing products whose color requirement is not black.

[0059] According to Embodiment 1 of this application, the implementation principle of an injection molding equipment is as follows: During the injection molding process of the injection molding device 1, the waste material generated falls onto the conveyor belt 2. The conveyor belt 2 transports the waste material to the top of the loading box 4. The waste material falls into the loading box 4 along the moving direction of the conveyor belt 2. The power component 14 is activated, and the power component 14 drives the drive rod 92 to slide. The drive rod 92 drives the drive frame 91 to slide. The drive frame 91 drives the pusher plate 8 to move. The pusher plate 8 transfers the waste material in the loading box 4 towards the suction block 6. The suction device 5 sucks up the waste material in the loading box 4 through the suction block 6 and supplies the waste material in the loading box 4 into the injection molding device 1. The injection molding device 1 processes the waste material to produce the required product. The staff only needs to insert the suction head of the suction device 5 into the snap-fit ​​slot 22 to connect the suction head of the suction device 5 to the suction block 6, which makes it easy to suck up the waste material in the feeding box 4. The push plate 8 pushes the waste material in the feeding box 4 towards the suction block 6, thereby avoiding the need for the staff to manually move the suction head of the suction device 5 to suck up the waste material in the feeding box 4, saving the staff a lot of time.

[0060] Example 2,

[0061] Example 2 discloses an injection molding machine, comprising the following steps:

[0062] Reference Figure 1 and Figure 6 The raw material supply involves workers pouring the raw materials to be processed onto the conveyor belt 2 or into the feeding box 4. The raw materials on the conveyor belt 2 are poured into the feeding box 4 as the conveyor belt 2 is running. The raw materials in the feeding box 4 are used to supply the injection molding device 1, which is used to produce the required products.

[0063] Reference Figure 1 and Figure 6 The process involves the worker inserting the suction head of the suction device 5 into the suction block 6. Under the suction of the suction device 5, the raw material enters the suction block 6 and then enters the suction device 5 to supply the injection molding device 1.

[0064] Reference Figure 2 and Figure 6 The material pushes the power component 14, which drives the drive rod 92 to slide. The drive rod 92 drives the drive frame 91 to slide. Driven by the drive frame 91, the pusher plate 8 moves. The pusher plate 8 pushes the material on the top layer of the feeding box 4 toward the suction block 6. The drive component 20 drives the drive rod 92 to reciprocate, thereby transporting the material in the feeding box 4 to the vicinity of the suction block 6.

[0065] Reference Figure 1 and Figure 6Waste disposal: During the injection molding process, the injection molding device 1 generates waste material. The waste material falls from the outlet of the injection molding device 1 into the cutting device 3. The cutting device 3 cuts the waste material, and the cut waste material falls from the outlet of the cutting device 3 onto the conveyor belt 2. Under the transport of the conveyor belt, it falls into the loading box 4 as raw material for subsequent injection molding of the injection molding device 1.

[0066] Reference Figure 1 and Figure 6 The raw materials are processed, and the waste material after cutting is put into the feeding box 4. The suction device 5 picks up the waste material in the feeding box 4 and supplies the waste material to the injection molding device 1. The injection molding device 1 re-injects the waste material generated during the injection molding process into the product.

[0067] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
