Description

Technical Field

[0001] This utility model relates to the field of injection molds, and in particular to a high-efficiency two-color one-piece injection mold. Background Technology

[0002] Two-color injection molds are a special type of injection mold that allows two different colors of plastic to be injected on the same injection molding machine. Through two molding processes, the final product is ejected from the mold only once. This process is typically used to produce products with two colors or different materials.

[0003] Existing two-color one-piece high-efficiency injection molds do not have an automatic mold release agent spraying structure. The mold release agent cannot be automatically sprayed before injection molding, which easily leads to sticking during injection molding, affecting work efficiency and production costs.

[0004] Therefore, to address the issue that existing two-color one-piece high-efficiency injection molds lack an automatic mold release agent spraying structure, resulting in mold sticking during injection and impacting work efficiency and production costs, a two-color one-piece high-efficiency injection mold can be designed. By incorporating a drive motor, the output end of the motor rotates a screw during operation. The screw's rotation drives a threaded moving seat to reciprocate left and right. This moving seat then moves the mounting plate and mold release agent tank synchronously. When the push-type discharge head on the left side of the mold release agent tank contacts the left side wall of the mounting groove, it is compressed, drawing the mold release agent from the tank through a hose into the spray nozzle and spraying it out in a mist form, thus completing the automatic spraying of the mold release agent. Utility Model Content

[0005] To overcome the problem that existing two-color one-piece high-efficiency injection molds do not have an automatic mold release agent spraying structure, and cannot automatically spray mold release agent before injection, resulting in sticking during injection, affecting work efficiency and production costs.

[0006] The technical solution of this utility model is as follows: a dual-color integrated high-efficiency injection mold, including a first mounting plate; it also includes a mounting groove, a drive motor, a screw, a movable seat, a mounting plate, a mold release agent tank, a press-type discharge head, a hose, a fixing groove, and a spray head. Two main molds are provided on the front surface of the first mounting plate. The top surface of the two main molds is provided with mounting grooves. A drive motor is embedded in the left front position of the inner surface of the mounting groove. One end of the screw is provided at the output end of the drive motor. The other end of the screw is rotatably connected to the right side of the inner surface of the mounting groove. The outer surface of the screw is threadedly connected to the movable seat. A mounting plate is provided on the rear surface of the movable seat. A mold release agent tank is provided on the upper surface of the mounting plate. A press-type discharge head is provided on the left side surface of the mold release agent tank. One end of the hose is provided on the front surface of the press-type discharge head. A positioning groove is provided on the front surface of the main mold. A fixing groove is provided on the upper side of the inner surface of the positioning groove. A spray head is provided inside the fixing groove. The other end of the hose is connected to the spray head.

[0007] Preferably, by setting a drive motor, its output end will drive the screw to rotate during operation. When the screw rotates, it will drive the moving seat that is threaded with it to move back and forth. The moving seat will drive the mounting plate and the mold release agent tank to move synchronously. When the press-type discharge head on the left side of the mold release agent tank contacts the left side wall of the mounting groove, the press-type discharge head is squeezed, thereby introducing the mold release agent inside the mold release agent tank into the spray head through the hose and spraying it out in a mist form, thus completing the automatic spraying of the mold release agent. This solves the problem that the existing two-color one-piece high-efficiency injection mold itself does not have an automatic mold release agent spraying structure when in use. It cannot automatically spray the mold release agent before injection, which easily leads to mold sticking during injection, affecting work efficiency and production costs.

[0008] Preferably, the upper surface of the mounting plate is provided with two symmetrical annular clips, and the release agent can is connected to the mounting plate through the annular clips.

[0009] Preferably, mounting screw holes are provided at the rear corners of the inner surface of the positioning groove.

[0010] Preferably, a drain plate is provided at the bottom of the positioning groove inside the main mold, and a recycling box is provided on the lower side of the drain plate inside the main mold.

[0011] Preferably, a baffle is inserted inside the drain plate, and a slot is opened at the lower position of the right side surface of the main mold. A servo motor is set at the top front position of the inner surface of the slot, and a gear is set at the output end of the servo motor. The right side surface of the baffle is set with meshing teeth, and the gear meshes with the meshing teeth.

[0012] Preferably, a sealing door is provided on the front surface of the main mold corresponding to the position of the recycling box, and the sealing door is rotatably connected to the main mold via a hinge.

[0013] Preferably, positioning holes are provided at the corners of the front surface of the main mold, and the front side of the main mold is connected to the auxiliary mold through the positioning holes. The front surface of the auxiliary mold is provided with a second mounting plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a drive motor, its output end will drive the screw to rotate during operation. When the screw rotates, it will drive the moving seat that is threaded with it to move back and forth. The moving seat will drive the mounting plate and the mold release agent tank to move synchronously. When the press-type discharge head on the left side of the mold release agent tank contacts the left side wall of the mounting groove, the press-type discharge head is squeezed, thereby introducing the mold release agent inside the mold release agent tank into the spray head through the hose and spraying it out in a mist form, thus completing the automatic spraying of the mold release agent. This solves the problem that the existing two-color one-piece high-efficiency injection mold itself does not have an automatic mold release agent spraying structure when in use. It cannot automatically spray the mold release agent before injection, which makes it easy for the mold to stick during injection, affecting work efficiency and production costs.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a two-color integrated high-efficiency injection mold, including a first mounting plate 1; it also includes a mounting groove 3, a drive motor 4, a screw 5, a movable seat 6, a mounting plate 7, a mold release agent tank 8, a press-type discharge head 9, a hose 10, a fixing groove 11, and a spray head 12. Two main molds 2 are provided on the front surface of the first mounting plate 1. The top surfaces of both main molds 2 are provided with mounting grooves 3. A drive motor 4 is embedded in the left front position of the inner surface of the mounting groove 3. One end of a screw 5 is provided at the output end of the drive motor 4. The other end of the screw 5 is rotatably connected to the right side of the inner surface of the mounting groove 3. A movable seat 6 is threaded through the outer surface of the screw 5. A mounting plate 7 is provided on the rear surface of the movable seat 6. A mold release agent tank 8 is provided on the upper surface of the mounting plate 7. A press-type discharge head is provided on the left side surface of the mold release agent tank 8. 9. A hose 10 is provided on the front surface of the press-type discharge head 9. A positioning groove 14 is provided on the front surface of the main mold 2. A fixing groove 11 is provided on the upper side of the inner surface of the positioning groove 14. A spray head 12 is provided inside the fixing groove 11. The other end of the hose 10 is connected to the spray head 12. By setting a drive motor 4, its output end will drive the screw 5 to rotate during operation. When the screw 5 rotates, it will drive the moving seat 6 that is threaded with it to move back and forth. The moving seat 6 will drive the mounting plate 7 and the mold release agent tank 8 to move synchronously. When the press-type discharge head 9 on the left side of the mold release agent tank 8 contacts the left side wall of the mounting groove 3, the press-type discharge head 9 is squeezed, thereby introducing the mold release agent inside the mold release agent tank 8 into the interior of the spray head 12 through the hose 10 and spraying it out in a mist form, thereby completing the automatic spraying of the mold release agent.

[0025] Please see Figures 2-6In this embodiment, the upper surface of the mounting plate 7 is provided with two symmetrical annular buckles 13. The release agent tank 8 is connected to the mounting plate 7 through the annular buckles 13. The annular buckles 13 allow workers to quickly disassemble and assemble the release agent tank 8, facilitating daily replacement. The inner surface of the positioning groove 14 is provided with mounting screw holes 15 at the rear corners. The mounting screw holes 15 facilitate the replacement of different mold plates by workers, making the operation relatively simple. The main mold 2 is provided with a drain plate 16 at the bottom of the positioning groove 14. The main mold 2 is provided with a recycling box 17 below the drain plate 16. By providing the drain plate 16 and the recycling box 17, the excess release agent sprayed can flow into the recycling box 17 under the action of gravity through the drain plate 16, thereby reducing waste.

[0026] Please see Figures 1-6 In this embodiment, a baffle 18 is inserted inside the drain plate 16. A slot 19 is provided on the lower right side surface of the main mold 2. A servo motor 21 is provided at the top front of the inner surface of the slot 19. A gear 22 is provided at the output end of the servo motor 21. A meshing tooth 20 is provided on the right side surface of the baffle 18. The gear 22 meshes with the meshing tooth 20. By providing the servo motor 21, its output end will drive the gear 22 to rotate during operation. When the gear 22 rotates, it cooperates with the meshing tooth 20 to drive the baffle 18 to move. Thus, after the release agent is sprayed, the top of the recycling box 17 can be closed to prevent the first mounting plate 1 from rotating. During the changeover, if the release agent spills, a sealing door 23 is provided on the front surface of the main mold 2 corresponding to the position of the recycling box 17. The sealing door 23 is rotatably connected to the main mold 2 via a hinge. By setting the sealing door 23, the recycling box 17 can be limited while achieving a good sealing effect, preventing the release agent inside the recycling box 17 from solidifying. Positioning holes 24 are provided at the corners of the front surface of the main mold 2. The front side of the main mold 2 is connected to the auxiliary mold 25 through the positioning holes 24. The front surface of the auxiliary mold 25 is provided with a second mounting plate 26. By setting the positioning holes 24, the docking accuracy between the main mold 2 and the auxiliary mold 25 can be improved, thereby improving the injection molding quality.

[0027] During operation, the ring buckle 13 allows workers to quickly disassemble and assemble the release agent can 8, facilitating daily replacement. The mounting screw hole 15 allows workers to easily change different mold plates, making operation simple. The drain plate 16 and recycling box 17 allow excess release agent sprayed out to flow into the recycling box 17 under gravity, reducing waste. The servo motor 21 drives the gear 22 to rotate during operation. The gear 22, when rotating, engages with the meshing gear 20 to move the baffle 18, closing the top of the recycling box 17 after spraying the release agent, preventing leakage of release agent when the first mounting plate 1 rotates. The sealing door 23 limits the position of the recycling box 17 while providing a good seal, preventing the release agent inside the recycling box 17 from solidifying. The positioning hole 24 improves the docking accuracy between the main mold 2 and the auxiliary mold 25, thereby improving injection molding quality.

[0028] Through the above steps, by setting the drive motor 4, its output end will drive the screw 5 to rotate during operation. When the screw 5 rotates, it will drive the moving seat 6, which is threaded with it, to move back and forth. The moving seat 6 will drive the mounting plate 7 and the mold release agent tank 8 to move synchronously. When the press-type discharge head 9 on the left side of the mold release agent tank 8 contacts the left side wall of the mounting groove 3, the press-type discharge head 9 is squeezed, thereby introducing the mold release agent inside the mold release agent tank 8 into the spray head 12 through the hose 10 and spraying it out in a mist form, thus completing the automatic spraying of the mold release agent. This solves the problem that the existing two-color one-piece high-efficiency injection mold itself does not have an automatic mold release agent spraying structure when in use, and cannot automatically spray the mold release agent before injection, which easily leads to mold sticking during injection, affecting work efficiency and production costs.
