Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figures 1-6 In this embodiment of the utility model, a material dispensing injection molding machine includes a base 1, a fixed rod 2 fixedly connected to the base 1, a fixed seat 3 fixedly connected to the fixed rod 2, a mounting seat 4 fixedly connected to the top of the fixed rod 2, a hydraulic telescopic cylinder 6 fixedly connected to the mounting seat 4, a punch 7 fixedly mounted on the mounting seat 4 through the output shaft of the hydraulic telescopic cylinder 6, and a die 5 fixedly mounted on the upper surface of the fixed seat 3, the punch 7 and the die 5 cooperating with each other, an injection pipe 14 communicating with the die 5 fixedly connected to the bottom of the fixed seat 3, an opening and closing control component installed inside the injection pipe 14, and a fixed connection at the bottom of the injection pipe 14. A material distribution valve 16 is rotatably connected to a material distribution head 17. Multiple sets of connectors 20 are provided on the outer wall of the material distribution valve 16. Each set of connectors 20 is connected to a set of injection molding components. The connectors 20 are connected to the injection pipe 14 through the material distribution valve 16. The material distribution head 17 is rotatably installed at the connection between the material distribution head 17, the material distribution valve 16, and the injection pipe 14. A discharge groove 19 is provided inside the material distribution head 17. The discharge groove 19 connects the connectors 20 and the injection pipe 14. A servo motor 18 is fixedly installed on the material distribution valve 16. The output shaft of the servo motor 25 is fixedly connected to the material distribution head 17.

[0021] This invention first heats different raw materials by setting up multiple sets of injection molding components. Then, when different types of raw materials need to be injected, the servo motor 25 drives the dispensing head 17 to rotate precisely within the dispensing valve 16, thereby precisely controlling the position of the discharge trough 19. At this time, the discharge trough 19 can be connected to the injection molding component of the required raw material. The molten raw material enters the discharge trough 19 along the connector 20, and then enters the injection tube 14 from the discharge trough 19, finally entering between the cavity mold 5 and the punch mold 7. At the same time, when another raw material needs to be injected, the servo motor 25 drives the dispensing head 17 to rotate, thereby adjusting the position of the discharge trough 19, so that the injection molding component connected to the discharge trough 19 can be replaced, thus realizing the rapid replacement of injection molding raw materials.

[0022] In one instance of this embodiment, please refer to Figures 1-6 The injection molding assembly includes an injection tube 21 fixedly installed on the base 1. A sealing plug 22 is installed at the discharge end of the injection tube 21. The sealing plug 22 and the connector 20 are sealed to each other. A feeding hopper 23 is fixedly connected to the tail of the injection tube 21. A screw 24 is rotatably connected inside the injection tube 21. A motor 25 is installed at the tail of the injection tube 21. The output shaft of the motor 25 is fixedly connected to the drive end of the screw 24.

[0023] The injection molding assembly holds the raw material through the feeding hopper 23 and drives the screw 24 to rotate through the motor 25. The screw 24 then rotates and squeezes the raw material in the feeding hopper 23. At the same time, the raw material is heated through the injection tube 21. The heated raw material is injected into the dispensing valve 16 along the sealing plug 22 and the connector 20.

[0024] In one instance of this embodiment, please refer to Figures 1-6 The opening and closing control assembly includes a switching valve 15 rotatably installed in the injection tube 14, a drive rod 12 rotatably connected to the bottom of the die 5, one end of the drive rod 12 being fixedly connected to the switching valve 15, and the other end of the drive rod 12 being fixedly connected to a drive gear 13. A spring groove is provided on the edge of the die 5, and a sliding connecting rod 8 is slidably connected in the spring groove. A rack 11 is fixedly connected to the bottom of the sliding connecting rod 8, and the rack 11 meshes with the drive gear 13. A contact 9 is fixedly connected to the top of the sliding connecting rod 8, and the contact 9 cooperates with the edge of the punch 7. A stop block is fixedly connected to the sliding connecting rod 8 in the spring groove, and a return spring 10 installed in the spring groove is provided on the side of the stop block away from the contact 9.

[0025] When the die 5 and the punch 7 are closed, the punch 7 compresses the contact 9, thereby compressing the contact 9 into the spring groove. The contact 9 drives the sliding connecting rod 8 to press down, and compresses the return spring 10 through the stop block. The sliding connecting rod 8 drives the rack 11 to slide and extend. The rack 11 drives the drive gear 13 to rotate through mutual meshing with the drive gear 13. The drive gear 13 drives the switching valve 15 to rotate through the drive shaft. At this time, the switching valve 15 opens, and the injection pipe 14 is connected. Then, when the die 5 is raised, the return spring 10 releases its elastic potential energy, thereby controlling the switching valve 15 to reset, thus closing the switching valve 15.
