Description

Technical Field

[0001] The present invention relates to the technical field of mold cooling, and specifically relates to a rapid cooling device for plastic molds. Background Art

[0002] A plastic mold is a short name for a combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. Coordinated changes in the convex and concave molds of the mold and the auxiliary molding system can process a series of plastic parts with different shapes and sizes. During the injection molding process, cooling water needs to be introduced into the cooling pipeline to timely discharge the heat generated by the mold, preventing the plastic from deforming and fading due to high temperature, thereby ensuring the surface finish and dimensional accuracy of plastic products.

[0003] The cooling pipelines of most molds are usually connected in series with each other through elbow joints. During the process of processing more than two thousand plastic molds, water can only enter from the water inlet end. After flowing to the water outlet end, the liquid level can slowly rise, and then the pipeline can be filled with water. Moreover, the replacement rate of the cooling water is relatively slow. When part of the pipeline is blocked, the entire pipeline needs to be cleaned or replaced. Summary of the Invention

Detailed implementation manners

[0027] Please refer to Figures 1 - 3 In an embodiment of the present invention, a rapid cooling device for a plastic mold includes a plastic mold 1. A cooling groove for burying pipelines is provided on the side wall of the plastic mold 1. Symmetric connecting blocks 10 are arranged in the inner cavity of the cooling groove. A flow-stabilizing pipe 7 and a cooling pipe 6 for cooling are arranged between the symmetric connecting blocks 10. The cooling pipe 6 is located above the flow-stabilizing pipe 7. A plurality of uniformly distributed flow-through holes 9 are provided at the upper end of the cooling pipe 6. The space in the inner cavities of the cooling pipe 6 and the flow-stabilizing pipe 7 is connected through the opened flow-through holes 9. The water flow will enter the cooling pipe 6 through the flow-through holes 9 only after entering the flow-stabilizing pipe 7 and filling the inner cavity of the flow-stabilizing pipe 7. The water flow enters the inner cavity of the cooling pipe 6 evenly through a plurality of flow-through holes 9, so that the water flow can quickly fill the inside of the cooling pipe 6, and then cool the mold. Moreover, through the cooperation of the cooling pipe 6 and the flow-stabilizing pipe 7, while ensuring the cooling area of the outer wall of the cooling pipe 6, the inner cavity space of the cooling pipe 6 is compressed internally, so that the water flow in the inner cavity of the cooling pipe 6 can flow quickly, thereby improving the cooling effect on the mold, and achieving the purpose of rapid cooling in this way. A positioning mechanism for installing and fixing the connecting block 10 in the inner cavity of the cooling groove is arranged on the side of the connecting block 10 away from the cooling pipe 6. When the side of the positioning mechanism away from the connecting block 10 rotates clockwise, the side wall of the positioning mechanism approaches the inner cavity side wall of the cooling groove.

[0028] Please refer to Figure 4, The positioning mechanism includes a housing 5. A fixed ring 24 is fixedly connected to the middle of the housing 5. Symmetrical flow dividing pipes 2 are fixedly connected to the outer wall of the plastic mold 1. A plurality of connecting pipes 4 are fixedly connected above the symmetrical flow dividing pipes 2. The number and positions of the connecting pipes 4 correspond to those of the housing 5. A water pipe 3 is fixedly connected to the middle of the lower end of the flow dividing pipe 2. Water is injected into the flow dividing pipe 2 through the water pipe 3. A through hole for the insertion of the connecting pipe 4 is provided in the middle of the fixed ring 24. One end of the connecting pipe 4 away from the flow dividing pipe 2 is inserted into the through hole and is communicated with the inner cavity of the flow stabilizing pipe 7. Through the cooperation of the flow dividing pipe 2 and the connecting pipe 4, water is evenly delivered into the inner cavity of the flow stabilizing pipe 7 and finally enters the cooling pipe 6 through the flow through holes 9. One side of the connecting pipe 4 is communicated with the inner cavity of the flow stabilizing pipe 7, while the other side of the connecting pipe 4 is communicated with the inner cavity of the cooling pipe 6. Thus, water flows from the inner cavity of the flow stabilizing pipe 7 into the inner cavity of the cooling pipe 6 and flows out under the action of the connecting pipe 4 connected to the cooling pipe 6, thereby completing the water circulation of flowing into the cooling pipe 6 from the flow stabilizing pipe 7.

[0029] For plastic products of different shapes, the shapes of the molds provided in the inner cavity of the plastic mold are also different. When cooling the inner cavity of an arc-shaped or "concave"-shaped mold, the positions of the cooling pipes also need to be changed accordingly, so as to ensure that during the injection molding process, plastic products of different shapes can be cooled evenly and quickly, thereby ensuring the quality of the plastic products. In this solution, a plurality of separate flow stabilizing pipes 7 are connected in parallel with the flow dividing pipe 2 through the connecting pipes 4, so that when the shape of the mold changes, the positions of the flow stabilizing pipes 7 can also change accordingly. The connecting pipe 4 is composed of a hard pipe and a flexible pipe. That is, the part of the connecting pipe 4 inserted into the through hole is a hard pipe, and the rest of the part is composed of a flexible pipe. Even if the distance between the flow stabilizing pipe 7 and the flow dividing pipe 2 increases, it will not affect the connection function of the connecting pipe 4. The position of the flow stabilizing pipe 7 can be changed accordingly according to the change in the position of the cooling groove provided on the side wall of the plastic mold 1. Since a plurality of flow stabilizing pipes 7 exist in a parallel connection form, the change in the position of a single or several flow stabilizing pipes 7 will not affect other flow stabilizing pipes 7. And by changing the position of the flow stabilizing pipe 7, it is also possible to enable each surface of the plastic product to be cooled quickly and evenly during the injection molding process, thereby improving the quality of the injection molding while increasing the injection molding efficiency.

[0030] Please refer to Figure 4 , Figure 5 and Figure 8, a ratchet wheel 11 is rotatably connected to the middle of the inner cavity of the housing 5. A wedge block 29 is vertically and slidably connected to one side of the inner cavity of the housing 5 close to the cooling pipe 6. The lower end of the wedge block 29 is engaged with the outer wall of the ratchet wheel 11. The upper part of the wedge block 29 is elastically connected to the side wall of the inner cavity of the housing 5 close to the cooling pipe 6 by a spring. An inclined surface is provided on one side of the lower part of the wedge block 29. That is, when the ratchet wheel 11 rotates clockwise, the teeth of the ratchet wheel 11 contact the inclined surface, thereby jacking up the wedge block 29. After the teeth of the ratchet wheel 11 are separated from the wedge block 29, the wedge block 29 resets under the action of the elastic force, thereby restricting the counterclockwise rotation of the ratchet wheel 11. A driven ring 18 is fixedly connected to the middle of one side of the ratchet wheel 11 away from the cooling pipe 6. A driving ring 17 is sleeved on the outer wall of the driven ring 18. One end of the driving ring 17 away from the ratchet wheel 11 extends out of the side wall of the housing 5 away from the cooling pipe 6. The driving ring 17 is movably connected to the housing 5. An arc-shaped block 22 is fixedly connected to one side of the ratchet wheel 11 away from the driving ring 17. An arc-shaped groove 23 slidably matched with the arc-shaped block 22 is provided on the side wall of the inner cavity of the housing 5. The side wall of the arc-shaped block 22 is elastically connected to the side wall of the inner cavity of the arc-shaped groove 23 by a spring. That is, when the ratchet wheel 11 loses the limit of the wedge block 29, the arc-shaped block 22 resets under the action of the elastic force, thereby driving the ratchet wheel 11 to reset. By rotating the driving ring 17 clockwise, the ratchet wheel 11 can be driven to rotate clockwise through the driven ring 18, and the counterclockwise rotation of the ratchet wheel 11 is restricted by the wedge block 29. Cavities 12 are provided in the middle of both sides of the ratchet wheel 11. Symmetric cross bars 14 are attached to the side walls of the inner cavities of the cavities 12. The symmetric cross bars 14 are fixedly connected together at one end away from the cavities 12. A silica gel block 13 is horizontally slidably connected to the side wall of the housing 5. One end of the cross bar 14 away from the silica gel block 13 is fixedly connected to a driven rod 15. A guide groove 16 slidably matched with the outer wall of the driven rod 15 is provided on the side wall of the inner cavity of the cavity 12. When the ratchet wheel 11 has not rotated yet, at this time, the end of the guide groove 16 close to the driven rod 15 is closer to the center position of the ratchet wheel 11. When the ratchet wheel 11 rotates clockwise with the driving ring 17, under the sliding cooperation of the guide groove 16 and the driven rod 15, the silica gel block 13 can be driven to move horizontally until the silica gel block 13 contacts the inner wall of the cooling groove, thereby fixing the housing 5 in the cooling groove, and further completing the installation and fixation of the cooling pipe 6 and the flow stabilizing pipe 7.

[0031] Please refer to Figure 6, a ring groove 26 is formed on the outer wall of the fixed ring 24. On one side of the inner cavity of the active ring 17 close to the fixed ring 24, symmetric extrusion plates 25 are fixedly connected. The side of the extrusion plate 25 away from the active ring 17 is in contact with the bottom of the inner cavity of the ring groove 26. The horizontal width of the ring groove 26 is greater than the horizontal width of the extrusion plate 25. Symmetric grooves are formed on the side wall of the inner cavity of the ring groove 26. The position of the grooves is close to the position where the extrusion plates 25 are located. A U-shaped block 27 is slidably connected to the inner cavity of the groove. A spring is elastically connected between the bottom of the inner cavity of the groove and the top of the inner cavity of the U-shaped block 27. After one end of the connecting pipe 4 away from the shunt pipe 2 is inserted into the inner cavity of the through hole, the active ring 17 is rotated to drive the extrusion plate 25 to move along the ring groove 26, so that the side wall of the extrusion plate 25 contacts the side wall of the U-shaped block 27, and thus the U-shaped block 27 is squeezed toward the center of the through hole, so that the lower end of the U-shaped block 27 contacts the outer wall of the hard pipe, thereby clamping and fixing the hard pipe. As the pipeline continuously cools the plastic mold, water continuously flows between the steady flow pipe 7 and the cooling pipe 6. After long-term use, in order to ensure the cooling effect of the pipeline, the fouled or blocked pipeline needs to be cleaned and maintained. Since multiple cooling pipes 6 and steady flow pipes 7 are connected in parallel, the fouling conditions inside multiple cooling pipes 6 and steady flow pipes 7 may be different. When only some pipelines are fouled, for the cooling pipelines connected in series, the blockage or fouling of some pipelines will affect the overall water flow. However, when the cooling pipelines are connected in parallel, only the cooling effect of the blocked pipeline will be affected, and there are no bends between the parallel pipelines, so the cleaning is faster. When cleaning, only the position of the active ring 17 corresponding to the blocked pipeline needs to be found, and then the extrusion plate 25 is driven by the active ring 17 to move away from the position where the U-shaped block 27 is located, so that the connecting pipe 4 can be disassembled, and the cleaning pipeline can be connected to the through hole, so as to flush the blocked steady flow pipe 7 and cooling pipe 6. By increasing the pressure to increase the flow rate of the cleaning liquid, the cleaning of the blocked pipeline can be quickly completed. When the whole needs to be cleaned, only the cleaning pipeline needs to be connected to the water pipe 3.

[0032] Please refer to Figure 7, on one side of the inner cavity of the active ring 17 close to the ratchet wheel 11, symmetric driving rods 21 are fixedly connected. On the outer wall of the driven ring 18, balance grooves 19 that are centrosymmetric about the center of the driven ring 18 are provided. At one end of the balance groove 19 close to the driving rod 21, a fitting groove 20 is provided. The outer wall of the end of the driving rod 21 away from the active ring 17 is slidably connected in the fitting groove 20 and the balance groove 19. When it is necessary to separately release the fixation of the U-shaped block 27 on the hard pipe, the active ring 17 is pulled in the direction away from the flow stabilizer pipe 7, thereby driving the driving rod 21 to move from the inner cavity of the fitting groove 20 into the balance groove 19. At this time, the active ring 17 is rotated counterclockwise, and the pressing plate 25 can be driven to rotate counterclockwise, so that the pressing plate 25 is separated from the U-shaped block 27. The U-shaped block 27 moves away from the position where the hard pipe is located under the action of elastic force, and the driving rod 21 will move along the inner cavity of the balance groove 19. During this process, the ratchet wheel 11 and the driven ring 18 remain stationary. And when the active ring 17 is rotated clockwise again, after the driving rod 21 moves to the connection between the fitting groove 20 and the balance groove 19, the active ring 17 is pushed in the direction of the flow stabilizer pipe 7, so that the driving rod 21 is located in the inner cavity of the fitting groove 20. After the active ring 17 fits with the side wall of the ratchet wheel 11, the U-shaped block 27 can be driven again to fix the hard pipe.

[0033] Please refer to Figure 9 and Figure 10When the cooling pipeline is aged and needs to be replaced, it is necessary to remove the shell 5 and the flow-stabilizing tube 7 from the cooling tank. Since the ratchet 11 is limited by the wedge block 29, the silicone block 13 cannot be reset by rotating the active ring 17 counterclockwise. A transverse groove 28 is provided on the outer wall of the shell 5 near the flow-stabilizing tube 7. The inner cavity of the transverse groove 28 is slidably connected with a driven block 30. The inner cavity of the driven block 30 is slidably connected with a symmetrical moving rod 32. A symmetrical elastic rod 31 is fixedly connected to the outer wall of one side of the driven block 30. A side of the moving rod 32 close to the elastic rod 31 is fixedly connected with an inclined block 33. The symmetrical moving rod 32 is fixedly connected to a sliding block 35 at one end away from the moving rod 32. The sliding block 35 is fixedly connected to a push plate 36 at one side away from the flow-stabilizing tube 7. By pulling the push plate 36, the sliding block 35 is fixedly connected to the push plate 36. The plate 36 can drive the sliding block 35 to move horizontally, and the sliding block 35 will drive the symmetrical elastic rod 31 to move horizontally. The elastic rod 31 will drive the moving rod 32 to approach the position of the driven block 30, and push the driven block 30 to move horizontally through the moving rod 32. A rope is fixedly connected to the middle part of the upper end of the wedge block 29, and the end of the rope away from the wedge block 29 passes through the inner cavity of the shell 5 and is fixedly connected to the middle part of the driven block 30, so that the wedge block 29 is driven away from the position of the ratchet 11 through the movement of the driven block 30, and the limit of the ratchet 11 is released, thereby completing the disassembly of the separate shell 5, and the elastic force of the spring acting on the wedge block 29 will also prevent the driven block 30 from moving due to the friction caused by the movement of the moving rod 32. When multiple shells need to be disassembled When the disassembly is completed synchronously, it is necessary to synchronously drive multiple push plates 36 to move. A coil spring is connected to the middle of the inner cavity of the driven block 30, and one end of the coil spring is fixedly connected to a traction rope 34. The traction rope 34 is flexible. Through the cooperation of the traction rope 34 and the coil spring, when the traction rope 34 is pulled, the traction rope 34 will continuously move outward from the inner cavity of the driven block 30. When the traction rope 34 loses its tension, it will automatically reel in the inner cavity of the driven block 30 under the action of the coil spring (the same as the working principle of the tape measure commonly used in the prior art). The end of the traction rope 34 away from the driven block 30 is fixedly connected to a clamping block 8. The outer wall of the sliding block 35 is provided with a clamping groove that is clamped and matched with the clamping block 8. When it is necessary to disassemble multiple shells 5 at the same time, it is only necessary to clamp the multiple clamping blocks 8 in sequence. The plurality of sliding blocks 35 are connected in series with each other through the cooperation of the card block 8 and the adjacent card slots, and then the push plate 36 at the edge is pushed to drive the sliding block 35 to move. At the same time, in order to avoid the relative movement of the driven block 30 at the edge and the traction rope 34, which causes the driven block 30 to move and the traction rope 34 to be relatively stretched, and cannot drive the adjacent sliding block 35 to move, when the moving rod 32 approaches the driven block 30, the moving rod 32 presses the elastic rod 31 downward, and the symmetrical elastic rod 31 is in close contact with the outer wall of the traction rope 34, so that the traction rope 34 is clamped and fixed by the elastic rod 31, thereby avoiding the situation that the driven block 30 moves and the traction rope 34 is relatively stretched.When the driven block 30 moves, since the traction rope 34 is clamped by the elastic rod 31 and cannot be further stretched, the traction rope 34 will move synchronously with the driven block 30 at this time. Furthermore, it can drive the adjacent sliding blocks 35 to move, thus achieving the effect of synchronous movement of multiple sliding blocks 35, and synchronously releasing the fixing effect between the housing 5 and the cooling groove. Then, the disassembly of multiple pipelines can be completed simultaneously, which is convenient for maintaining or replacing the pipelines. Moreover, the traction rope 34 is made of flexible material, so even if multiple housings 5 are not in the same horizontal plane, it does not affect the traction effect of the traction rope 34 on the adjacent sliding blocks 35.
