Description

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1 to 10 As shown, the present invention provides a technical solution: an integrated rubber sole production injection mold, comprising an injection platform 1, a cooling box 2 is provided on one side above the injection platform 1, a fixing frame 3 is fixedly connected to the top of the cooling box 2, an injection structure 5 is fixedly installed above the fixing frame 3, and a hydraulic cylinder 4 is fixedly connected to the output end of the injection structure 5, a lower mold 7 is provided on one side of the cooling box 2, the lower mold 7 is slidably connected to the injection platform 1, a middle mold 6 is slidably connected above the lower mold 7, a hinge seat 9 is fixedly connected to the top of the lower mold 7, an upper mold 8 is hinged to the inner wall of the hinge seat 9, the upper mold 8 is located above the middle mold 6, and driving components for driving the middle mold 6 to slide repeatedly along the top of the injection platform 1 are provided on both sides of the middle mold 6, a pushing component is provided on one side of the middle mold 6, and the pushing component includes two pushing blocks 16, which are used to push the plastic body out, and mold opening components are provided on both sides of the upper mold 8, and the mold opening component is used to drive the upper mold 8 to rotate with the shaft of the hinge seat 9 as the center point.

[0034] During operation: in the initial state, the hydraulic cylinder 4 is driven to descend by driving the injection structure 5, so that the hydraulic cylinder 4 is close to the two middle molds 6, and the internal molten rubber liquid is injected into the cavity of the middle mold 6. After the injection is completed, the middle mold 6, the lower mold 7 and the upper mold 8 are merged together to form a complete injection mold; start the driving component, the driving component will drive the middle mold 6 to move toward the inside of the cooling box 2, and when the middle mold 6 moves toward the inside of the cooling box 2, since one end of the middle mold 6 is in contact with one end of the lower mold 7, the middle mold 6 can drive the lower mold 7 and the upper mold 8 to move toward the inside of the cooling box 2 together. After the complete mold consisting of the entire middle mold 6, the lower mold 7 and the upper mold 8 moves to the inside of the cooling box 2, it can be cooled inside the cooling box 2 to form a solid rubber plastic body. After completion, the driving component drives the entire mold to move in the opposite direction and reset. After resetting, the driving component continues to drive the middle mold. 6 moves, at this time the lower mold 7 and the upper mold 8 remain in their original positions and do not move with the middle mold 6, so that the middle mold 6 can be pulled out from between the lower mold 7 and the upper mold 8 alone, and at this time the plastic body can not adhere to the inner walls of the lower mold 7 and the upper mold 8, but will remain alone in the internal cavity of the middle mold 6. After the middle mold 6 is completely pulled out, it will touch the pusher assembly to move, and the pusher assembly drives the two push blocks 16 to move to push out the internal plastic body, thereby achieving the effect of taking the material; after the material is taken out, the driving assembly drives the middle mold 6 to reset to between the lower mold 7 and the upper mold 8, and in this process drives the mold opening assembly to move, and the mold opening assembly drives the upper mold 8 to rotate with the shaft of the hinge seat 9 as the center point, so that the upper mold 8 is opened, and the hydraulic cylinder 4 is driven to descend by driving the injection structure 5 to perform the next round of injection work, and the sole production injection work is repeated in this way;

[0035] Through the above embodiment, the middle mold 6 slides along the injection table 1 through the driving component to realize the mold closing and opening actions with the lower mold 7 and the upper mold 8, and drives the complete closed mold as a whole into the cooling box 2 for cooling and solidification. After the mold is reset, the middle mold 6 is continued to be driven to move alone, so that it is pulled out from the mold closing gap between the lower mold 7 and the upper mold 8, completing the separation of the plastic body and the mold. The whole process of mold closing, cooling and demoulding is realized through a single driving source, reducing manual intervention; through the pushing component, after the middle mold 6 is completely pulled out, the pushing component is triggered to move. The push block 16 slides along the inner wall of the cavity of the middle mold 6 to push out the solidified rubber plastic body. Mechanical pushing replaces manual material removal to avoid plastic body adhesion or operator contact with high-temperature molds, thereby improving safety and production efficiency. Through the mold opening assembly, during the resetting process of the middle mold 6, the upper mold 8 is driven to rotate around the shaft of the hinge seat 9 to realize automatic opening of the upper mold 8. After the upper mold 8 is opened, a cavity entrance is provided for the next round of injection, ensuring that the hydraulic cylinder 4 can smoothly inject the molten rubber into the mold 6, replacing manual mold opening, reducing labor intensity and operation risks, and shortening the production cycle.

[0036] like Figure 3 and Figure 5 As shown, the drive assembly includes two electric slide rails 11, both of which are fixedly installed on the top of the injection table 1, and the interior of the electric slide rails 11 is slidably connected to an electric slider 12, and the top of the electric slider 12 is fixedly connected to a side connecting plate 10, and the two side connecting plates 10 are respectively fixedly connected to the middle position of both sides of the two middle molds 6.

[0037] During operation: the electric slider 12 slides synchronously along the electric slide rail 11 toward the cooling box 2, and drives the middle mold 6 to move through the side plate 10. One end of the middle mold 6 fits with the end of the lower mold 7, pushing the lower mold 7 to move synchronously. When the lower mold 7 moves, the upper mold 8 is driven to move synchronously through the hinge seat 9 to achieve the overall closure of the three-part mold and entry into the cooling box 2. The middle mold 6, the lower mold 7 and the upper mold 8 maintain a tight fit to form a closed cavity. After the entire mold completely enters the cooling box 2, the rubber plastic body is solidified and formed.

[0038] like Figure 3 and Figure 5 As shown, the bottoms of the two middle molds 6 are fixedly connected with sliders 14, the inner walls of the two lower molds 7 are symmetrically provided with slide grooves 13, the end of the slide groove 13 close to the cooling box 2 is in a closed state, the sliders 14 are respectively slidably connected to the inner walls of the slide groove 13 and adapted to each other, and the top of the injection station 1 is symmetrically fixedly connected with a limit block 15, which is located on one side of the lower mold 7 and has the same height as the lower mold 7.

[0039] During operation: Since the end of the slide 13 close to the cooling box 2 is in a closed state in the initial state, when the driving component drives the middle mold 6 to move toward the inside of the cooling box 2, under the restriction of the slide 13 and the slider 14, the middle mold 6 can drive the lower mold 7 and the upper mold 8 to enter the inside of the cooling box 2 together with it in a complete mold state for cooling; and after the middle mold 6, the lower mold 7 and the upper mold 8 are reset to their original positions, when the driving component continues to drive the middle mold 6 to move, under the restriction of the limit block 15, the lower mold 7 and the upper mold 8 remain in the current position and do not move, and the middle mold 6 will be pulled out separately, and the middle mold 6 is separated from the lower mold 7 and the upper mold 8. The plastic body remains in the cavity of the middle mold 6 due to adhesion, providing space for the subsequent pushing action of the pushing component.

[0040] like Figures 6 and 7 As shown, the pushing assembly also includes a clamping member 19, which is fixedly installed on the top of the injection platform 1. The inner wall of the clamping member 19 is rotatably connected to the rotating shaft 18, and an arc rod 17 is fixedly connected above the rotating shaft 18. The end of the arc rod 17 away from the rotating shaft 18 is fixedly connected to one side of the pushing block 16. A rotating assembly is provided below the rotating shaft 18, and the rotating assembly is used to drive the rotating shaft 18 to rotate.

[0041] During operation: When the middle mold 6 is pulled out from the lower mold 7 and the upper mold 8 alone, the rotating shaft 18 will be driven to rotate through the rotating assembly. The rotating shaft 18 drives the arc rod 17 to rotate about the axis, and the push block 16 at the end of the arc rod 17 moves synchronously. When the cavity of the middle mold 6 just moves to the bottom of the push block 16, the push block 16 just completes the rotation and enters the cavity. There is no interference between the two in the vertical direction. After the push block 16 enters the cavity, it continues to apply thrust along the extension direction of the arc rod 17 to eject the plastic body adhered to the cavity of the middle mold 6. The clamping part 19 is fixed on the injection table 1 or the frame to provide rigid support for the rotating shaft 18 to ensure the stability of the push block 16 when entering the cavity.

[0042] like Figures 6 and 7 As shown, the rotating assembly includes a connecting plate 20, which is fixedly connected to the bottom of the rotating shaft 18. Connecting blocks 21 are fixedly connected to both sides of the connecting plate 20, and a fixed push rod 37 is fixedly connected to one side of the side connecting plate 10. The fixed push rod 37 is located on one side of the connecting block 21.

[0043] During operation: the driving assembly drives the middle mold 6 to be withdrawn from the mold gap between the lower mold 7 and the upper mold 8, and the side connecting plate 10 moves synchronously with the middle mold 6. The fixed push rod 37 fixed on one side of the side connecting plate 10 gradually approaches the connecting blocks 21 on both sides of the connecting plate 20 below the rotating shaft 18. When the end of the fixed push rod 37 contacts the connecting block 21, the linear motion of the fixed push rod 37 is converted into a lateral thrust on the connecting block 21. After the connecting block 21 is subjected to the thrust, the rotating shaft 18 is driven by the connecting plate 20 to rotate around the bearing on the inner wall of the clamping member 19. The stroke of the fixed push rod 37 is precisely matched with the rotation angle of the connecting block 21, ensuring that the push block 16 accurately enters the cavity of the middle mold 6 under the drive of the arc rod 17. When the rotating shaft 18 rotates, the arc rod 17 drives the push block 16 to move along a predetermined arc. When the cavity of the middle mold 6 moves to just below the push block 16, the push block 16 just enters the cavity vertically and ejects the plastic body adhered to the cavity.

[0044] like Figures 6 and 7 As shown, the side of the clamping member 19 is fixedly connected to a receiving plate 22, and the sides of the two arc-shaped rods 17 and the connecting plate 20 are fixedly connected to a torsion spring 23, and one end of the torsion spring 23 away from the arc-shaped rod 17 and the connecting plate 20 is fixedly connected to the side of the receiving plate 22.

[0045] During operation: in the initial state, the torsion spring 23 is in a natural state, the arc rod 17 and the push block 16 are in the initial position, and when the end of the fixed push rod 37 contacts the connecting block 21, the linear motion of the fixed push rod 37 is converted into a lateral thrust on the connecting block 21. After the connecting block 21 is subjected to the thrust, it drives the rotating shaft 18 to rotate around the bearing on the inner wall of the clamping member 19 through the connecting plate 20; at this time, the arc rod 17 and the connecting plate 20 rotate together with the rotating shaft 18, and the torsion spring 23 is stretched to store elastic potential energy. After completing the pushing action, the driving assembly drives the middle mold 6 to reset, and the fixed push rod 37 gradually moves away from the connecting block 21. The torsion spring 23 releases the stored elastic potential energy, driving the arc rod 17, the push block 16 and the connecting plate 20 to rotate in the opposite direction and return to the initial position, preparing for the next pushing action.

[0046] like Figures 8 and 9 As shown, the mold opening assembly includes two gears 24, which are respectively fixedly connected to the two ends of the shaft of the hinge seat 9. A rack rod 25 is provided on one side of the gear 24. The teeth of the gear 24 can engage with the teeth of the rack rod 25. One end of the rack rod 25 is fixedly connected to a fixed plate 26, and a reverse thrust assembly is provided below the fixed plate 26. The reverse thrust assembly is used to drive the rack rod 25 to move toward the gear 24.

[0047] During operation: After the middle mold 6 is withdrawn and the material is discharged, it moves in the opposite direction to reset. During the reset process, it drives the fixed plate 26 to move toward the gear 24. During the movement, the teeth of the rack rod 25 can mesh with the teeth of the gear 24. Due to the certain gap between the teeth of the rack rod 25, the gear 24 will intermittently rotate during the continuous movement of the rack rod 25. During the rotation, the gear 24 will drive the upper mold 8 to gradually rotate around the shaft of the hinge seat 9 through the shaft of the hinge seat 9, thereby realizing the automatic opening of the upper mold 8, providing a cavity entrance for the next round of injection, and ensuring that the hydraulic cylinder 4 can smoothly inject the molten rubber into the mold 6.

[0048] like Figures 8 and 9 As shown, the reverse thrust assembly includes two hinged parts 29, which are respectively fixedly connected to the top of the two side plates 10, and the inner wall of the hinged part 29 is hinged with a hinged rod 28, the top of the hinged rod 28 is fixedly connected to the movable plate 27, and one side of the hinged rod 28 is fixedly connected to a torsion spring 230, and one end of the torsion spring 230 is fixedly connected to one side of the hinged part 29.

[0049] During operation: when the middle mold 6 is pulled out and moved to blank, it will drive the side plate 10 to move, and then drive the hinged rod 28 and the movable plate 27 to move together through the hinge 29; during the movement, the movable plate 27 moves along the bottom of the fixed plate 26, and at this time the torsion spring 2 30 is in a squeezed state; when the movable plate 27 moves to the side of the fixed plate 26, under the elastic reaction force of the torsion spring 2 30, the hinged rod 28 rotates, driving the movable plate 27 to lift a position, so that the side end of the movable plate 27 is against the side end of the fixed plate 26; then, when the electric slider 12 drives the middle mold 6 to reset in the opposite direction, the movable plate 27 will push the fixed plate 26 and the rack rod 25 to move together, so that the teeth of the rack rod 25 and the teeth of the gear 24 engage with each other.

[0050] like Figure 8 and Figure 10 As shown, one side of the movable plate 27 is fixedly connected to an inclined slide 1 31, one side of the inclined slide 1 31 is provided with an inclined slide 2 32, one side of the inclined slide 2 32 is fixedly connected to a support frame 33, and the support frame 33 is fixedly installed on the outer wall of the injection table 1.

[0051] During operation: when the middle mold 6 is reset to its original position, the upper mold 8 is fully opened, making full preparations for the subsequent injection of molten liquid; then, the driving assembly is started again to drive the complete mold composed of the middle mold 6, the lower mold 7 and the upper mold 8 to move toward the cooling box 2 to start a new round of cooling process; during the overall movement of the mold, the movable plate 27 moves synchronously, and the inclined slide 1 31 on its side gradually approaches and is squeezed by the inclined slide 2 32; because the inclined surfaces of the inclined slide 1 31 and the inclined slide 2 32 fit each other, under the action of the extrusion force, the movable plate 27 is forced to push downward, thereby driving the hinge rod 28 to rotate and the torsion spring 2 30 to be compressed; this series of actions enables the movable plate 27 to break away from the contact and squeezing state with the fixed plate 26, creating conditions for the reverse movement and reset of the rack rod 25; after the rack rod 25 moves in the reverse direction, it drives the gear 24 to rotate in the reverse direction, thereby causing the upper mold 8 to rotate in the reverse direction around the shaft of the hinge seat 9, preparing for the upper mold 8 to reclose and enter the interior of the cooling box 2.

[0052] like Figure 8 and Figure 10 As shown, one side of the cooling box 2 is symmetrically fixedly connected with an inner slide groove seat 35, the inner wall of the inner slide groove seat 35 is slidably connected with an inner slider 34, the bottom of the inner slider 34 is respectively fixedly connected to the top of the fixed plate 26, and one side of the inner slider 34 is fixedly connected with a return spring 36, and one end of the return spring 36 is fixedly connected to the inner wall surface of the inner slide groove seat 35.

[0053] During operation: when the middle mold 6 completes the extraction and blanking and reverse reset, the movable plate 27 pushes the fixed plate 26 and the rack rod 25 to move under the action of the reverse thrust assembly, and the teeth of the rack rod 25 engage with the gear 24 to drive the gear 24 to rotate, thereby gradually opening the upper mold 8; in this process, the fixed plate 26 drives the inner slider 34 to slide in the inner slide groove seat 35, and the inner slider 34 will squeeze the return spring 36 when sliding, so that the return spring 36 produces elastic deformation and stores elastic potential energy. When the fixed plate 26 is pushed, the inner slider 34 slides along the inner slide groove seat 35 and squeezes the return spring 36. After the movable plate 27 is released from contact and pushing, the return spring 36 pulls the inner slider 34 to slide in the reverse direction and reset.
