[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0026] An integrated extrusion injection molding machine is characterized by comprising an extruder body, with machine neck channels 2 connected to both sides of the extruder body outlet, and a three-way piston 3 connected to the other end of the machine neck channel 2. One outlet of the three-way piston 3 is connected to a storage cylinder 4, and the other end of the storage cylinder 4 is connected to a storage hydraulic cylinder 5, with the output piston of the storage hydraulic cylinder 5 extending into the storage cylinder 4 and sliding with a clearance fit against the inner wall of the storage cylinder 4. Another outlet of the three-way piston 3 is connected to an extrusion die 6, with a conveyor 13 located on one side of the lower part of the extrusion die 6, and a robotic arm 14 and a hydraulic press 7 located on one side of the conveyor 13. This integrated extrusion injection molding machine utilizes the conveyor 13 to transport the molten material extruded from the extruder body, and then uses the robotic arm 14 to place the molten material onto the hydraulic press 7 for molding. This can meet the production and processing needs of various raw materials, especially high-filling raw materials for clothing fibers, improving the yield rate and reducing processing time. Simultaneously, by setting up a storage cylinder for material storage, it ensures that the extruder is always working, further reducing waiting time and improving work efficiency.

[0027] Specifically, the main body of the extruder includes a main motor 1, a gearbox 17, a screw, and a barrel with a feed inlet. The output shaft of the main motor 1 is connected to the input shaft of the gearbox 17, the output shaft of the gearbox 17 is connected to the screw, and the barrel is sleeved on the outside of the screw. The barrel and the gearbox 17 are connected in a fixed structure.

[0028] It should be noted that a melt distributor 15 is connected to the outlet of the barrel, and three flow regulating valves 16 are connected to the rear of the melt distributor 15. Each of the three flow regulating valves 16 is connected to an extrusion die 6. By connecting the three extrusion dies 6 with the distributor, the purpose of diverting the flow is achieved, and the molten material can be directly distributed into each extrusion die 6, thereby increasing the output.

[0029] It should be noted that an installation platform 8 is provided on one side of the extrusion die 6, and a cutting device is fixedly installed on the installation platform 8 for cutting the molten material. The cutting device includes a cutting cylinder 9 and a cutter 10. The installation platform 8 is fixedly connected to the cutting cylinder 9, and the output shaft of the cutting cylinder 9 is fixedly connected to the cutter 10.

[0030] Specifically, the mounting platform 8 is provided with a fixed seat 11 for mounting the cutting cylinder 9. The fixed seat 11 is provided with a guide post 12 in a sliding structure. The guide post 12 is fixedly connected to the cutter 10 to ensure that the correct direction of movement is maintained during the cutting process.

[0031] To ensure the cutting effect, the cutter 10 is designed with a serrated structure.

[0032] The working principle and process of this utility model are as follows:

[0033] After the raw materials are uniformly mixed by the forced mixer, they are pushed into the forced feeder by the feeding screw, which forces the loose and lumpy fibrous material into the barrel. The main motor 1 drives the screw to rotate through the gearbox 17. An electric heater on the outside of the barrel melts and plasticizes the material. The plasticized raw material is extruded into the neck channel 2. The three-way piston 3 has positions A and B. When it is in position A, the extruder and the storage cylinder 4 are connected. The molten material enters the storage cylinder 4. After the storage is completed, the electronic ruler on the storage cylinder feeds back to the control system. The control system controls the three-way piston 3 to switch to position B. The storage cylinder 4 is connected to the extrusion die 6. The storage hydraulic cylinder 5 is driven by the servo hydraulic system to push the piston at the output end and inject the stored raw material into the extrusion die 6.

[0034] There are two sets of storage cylinders 4. When one set is finished storing material, the control system automatically switches to the other set to continue storing material. That is, when one set is injecting material, the other set is storing material. The two alternate, and the extruder continues to plasticize and extrude.

[0035] After the molten plasticized raw material is ejected from the extrusion die 6, it falls onto the conveyor belt 13. After the injection is complete, the cutting cylinder 9 drives the cutter 10 to cut it. The conveyor belt 13 then transports it to a designated position, where the robot arm 14 grabs the blank and places it into the die-casting mold of the hydraulic press 7 for die-casting. After cooling and molding, the mold of the hydraulic press 7 is opened, and the robot arm 14 removes the molded product from the mold and stacks it. At the same time, the extruder and the storage cylinder 4 continue to extrude and store material, operating continuously.
