Specific embodiments

[0027] Please refer to Figures 1-3 , in an embodiment of the present invention, a rapid cooling and temperature reduction device for a mold includes a fixed mold 1. A movable mold 2 is attached to the upper end surface of the fixed mold 1. An injection port is provided in the middle of the upper end of the movable mold 2. Symmetric mounting grooves 6 are provided in the middle of the side walls of the fixed mold 1 and the movable mold 2. A condensate pipe 5 is fixedly connected to the inner cavity of the mounting groove 6. A number of uniform cooling water tanks 8 are provided on one side of the inner cavity of the mounting groove 6 near the connection between the movable mold 2 and the fixed mold 1. That is, when the mold product has an arc-shaped surface, at this time, it is difficult for the condensate pipe 5 to fit the inner and outer surfaces of the product, resulting in a part of the product being closer to the condensate pipe 5 during injection molding, resulting in inconsistent cooling speeds of the product and affecting the quality of the product. By providing the cooling water tank 8, the water flow in the condensate pipe 5 can be made as close as possible to the outer wall of the injection product. The depth of the cooling water tank 8 can be adaptively changed according to the shape of the product, so that when the product is cooled, the cooling speeds of each part are as close as possible, improving the injection efficiency of the product and avoiding quality problems such as defects caused by uneven cooling of the product. A through groove 35 corresponding to the cooling water tank 8 is provided on the outer wall of the condensate pipe 5. A flow conversion mechanism is provided in the inner cavity of the condensate pipe 5. A driving mechanism is provided at the bottom of the inner cavity of the condensate pipe 5. When the driving mechanism moves horizontally, the flow conversion mechanism moves towards the inner cavity of the cooling water tank 8.

[0028] Please refer to Figures 4-5, the driving mechanism includes symmetric mounting blocks 3, the mounting blocks 3 are fixedly connected to both ends of the condensing pipe 5, water pipes 4 are respectively fixedly connected to the middle parts of the symmetric mounting blocks 3, symmetric threaded rods 7 are threadedly connected to the lower parts of the mounting blocks 3 on one side, the bottom of the inner cavity of the condensing pipe 5 is fixedly connected with a housing 12, symmetric adjusting plates 13 are slidably connected to the outer wall of the housing 12, and one end of the threaded rod 7 away from the mounting block 3 is rotatably connected to the middle part of the adjusting plate 13. When the threaded rod 7 is rotated, since the mounting block 3 is threadedly connected to the threaded rod 7 and the mounting block 3 cannot move, the threaded rod 7 will move horizontally towards the center position of the moving mold 2, thereby driving the adjusting plate 13 to move horizontally.

[0029] Please refer to Figure 5 and Figure 10 , the commutation mechanism includes a sleeve 10, a sealing ring 11 is fixedly connected to the outer wall of the lower part of the sleeve 10, the outer wall of the sleeve 10 is attached to the inner cavity side wall of the through groove 35, and the diameter of the sealing ring 11 is greater than the diameter of the sleeve 10. Therefore, when the sleeve 10 and the sealing ring 11 move towards the inner cavity of the cooling water tank 8, the sleeve 10 will enter the inner cavity of the cooling water tank 8 through the through groove 35, while the sealing ring 11 cannot pass through the through groove 35, so that the outer wall of the sealing ring 11 is attached to the top of the inner cavity of the condensing pipe 5. A sealing gasket is fixedly connected to the outer wall of the sealing ring 11, so that the inner cavities of the condensing pipe 5 and the cooling water tank 8 are communicated through the sleeve 10 and the sealing ring 11, and the sealing ring 11 will prevent the water flow in the condensing pipe 5 from flowing out through the gap between the through groove 35 and the cooling water tank 8.

[0030] Please refer to Figures 5-6 , symmetric driven rods 14 are fixedly connected to the lower end of the sealing ring 11, the positions of the driven rods 14 correspond to the positions of the adjusting plates 13, the distance between the symmetric driven rods 14 is greater than the distance between the symmetric adjusting plates 13, and the outer walls of the driven rods 14 are attached to the outer walls of the adjusting plates 13. A guide rod 15 is fixedly connected to the middle part of the lower end of the driven rod 14 close to the adjusting plate 13. A guide groove 16 slidably matched with the guide rod 15 is formed in the outer wall of the adjusting plate 13, and the outer wall of the end of the guide rod 15 away from the driven rod 14 is slidably connected to the inner cavity of the guide groove 16. The guide groove 16 is inclined towards the position where the threaded rod 7 is located. When the threaded rod 7 drives the adjusting plate 13 to move horizontally, at this time the guide groove 16 will move synchronously with the adjusting plate 13. Through the sliding fit between the guide groove 16 and the guide rod 15, the guide rod 15 and the driven rod 14 can be driven to move synchronously towards the inner cavity of the cooling water tank 8, thereby driving the sealing ring 11 and the sleeve 10 to move towards the inner cavity of the cooling water tank 8, and facilitating the water flow in the condensing pipe 5 to enter the cooling water tank 8 through the sleeve 10.

[0031] Please refer to Figures 7-8 and Figure 10The upper end surface of the sleeve 10 is fitted with a movable block 9, and the upper end of the movable block 9 is fixedly connected with a heightening ring. By setting the heightening ring, when the movable block 9 moves toward the inner cavity of the cooling water tank 8, the heightening ring can make a gap between the movable block 9 and the top of the inner cavity of the cooling water tank 8. Symmetrical through holes 31 are opened on the upper end of the movable block 9. A transmission member is arranged between the middle part of the lower end of the movable block 9 and the outer shell 12. The transmission member includes an inner rod 17 and a bottom rod 18. The upper end surface of the inner rod 17 is fixedly connected to the movable block 9, and the lower outer wall of the bottom rod 18 is fixedly connected to the outer shell 12. The inner rod 17 and the bottom rod 18 are transmission-connected by a plurality of sleeve rods 19, and the inner rod 17, the sleeve rod 19 and the bottom rod 18 are slidably connected by a sliding member. The moving parts include symmetrical sliders 23, and the lower ends of the outer walls of the inner rod 17 and the sleeve rod 19 are fixedly connected with symmetrical sliders 23. The inner cavity side walls of the sleeve rod 19 and the bottom rod 18 are provided with slide grooves 24 that slidably cooperate with the sliders 23, that is, the bottom rod 18 and the sleeve rod 19 are slidably connected through the slider 23 on the outer wall of the sleeve rod 19 and the slide groove 24 in the inner cavity of the bottom rod 18, and several sleeve rods 19 are also slidably connected through the slider 23 and the slide groove 24, the inner rod 17 and the adjacent sleeve rod 19 are slidably connected through the slider 23 on the outer wall of the inner rod 17 and the slide groove 24 in the inner cavity of the adjacent sleeve rod 19, and the inner rod 17, the sleeve rod 19 and the bottom rod 18 are sealed by a sealing gasket to prevent water from entering the inner cavity of the inner rod 17 and the sleeve rod 19.

[0032] See also Figure 7 The middle part of the lower end of the inner rod 17 and the middle part of the lower end of the plurality of sleeve rods 19 are provided with a movable hole 22, a spring 20 is fixedly connected between the inner cavity top of the inner rod 17 and the inner cavity bottom of the bottom rod 18, the diameter of the movable hole 22 is larger than the horizontal width of the spring 20, a cavity 25 is provided in the inner cavity of the outer shell 12, a driving plate 26 is slidably connected to the middle part of the lower side of the inner cavity of the cavity 25, a plurality of grooves 27 are provided at the upper end of the driving plate 26, the grooves 27 are located on the side of the lower part of the bottom rod 18 close to the threaded rod 7, a traction rope 21 is fixedly connected to the middle part of the inner cavity upper end of the inner rod 17, and the traction rope 21 is fixedly connected to the traction rope 21. One end of the rope 21 away from the inner rod 17 passes through a plurality of movable holes 22 and the middle part of the lower end of the bottom rod 18, and is fixedly connected to the side of the inner cavity of the groove 27 away from the threaded rod 7. The middle part of the inner cavity of the cavity 25 is transmission-connected to the side away from the threaded rod 7. The end of the electric push rod 28 close to the threaded rod 7 is transmission-connected to the drive plate 26, so that the drive plate 26 can be driven away from the position of the threaded rod 7 by the electric push rod 28, thereby driving the traction rope 21 to move toward the position of the drive plate 26, thereby pulling the inner rod 17 and the sleeve rod 19 to retract into the inner cavity of the bottom rod 18.

[0033] See also Figure 7 and Figure 9, during the downward movement of the inner rod 17, the movable block 9 will be driven to move downward synchronously. By opening the groove 27, when the traction rope 21 enters the inner cavity of the cavity 25 from the inner cavity of the bottom rod 18, the traction rope 21 can have sufficient moving space. When the condensate pipe 5 is installed into the inner cavity of the installation groove 6, at this time, the movable block 9 and the sleeve 10 are located in the inner cavity of the condensate pipe 5. Then, rotating the threaded rod 7 can drive the adjusting plate 13 to move horizontally. Through the sliding fit of the guiding groove 16 and the guiding rod 15, the driven rod 14, the sealing ring 11 and the sleeve 10 are driven to move into the inner cavity of the cooling water tank 8. Then, the electric push rod 28 drives the driving plate 26 to approach the position where the threaded rod 7 is located, so that the traction rope 21 loses the traction and pulling effect of the driving plate 26. At this time, under the action of the spring 20, the movable block 9 can be driven to move upward synchronously to the top of the inner cavity of the cooling water tank 8. By the way of driving the movable block 9 to move towards the inner cavity of the cooling water tank 8 by elastic force, when the depths of the inner cavities of several cooling water tanks 8 are different, it will not affect the movement of several movable blocks 9 to the tops of their corresponding cooling water tanks 8 respectively. And through the one-way transmission of the traction rope 21, the traction rope 21 will only affect the process of the movable block 9 moving away from the cooling water tank 8, that is, the traction rope 21 will only pull the movable block 9 away from the cooling water tank 8 and will not affect the process of the movable block 9 approaching the cooling water tank 8.

[0034] Please refer to Figures 1-3 and Figure 9 , and for the cooling water tanks 8 opened in the inner cavities of the fixed mold 1 and the movable mold 2, several cooling water tanks 8 in the fixed mold 1 are all located above the condensate pipe 5, while the cooling water tank 8 in the movable mold 2 is located below the condensate pipe 5. After the sleeve 10 enters the inner cavity of the cooling water tank 8, when water flow is added to the condensate pipe 5 through the water pipe 4, the water flow in the movable mold 2 can naturally enter the cooling water tank 8. At this time, the electric push rod 28 drives the driving plate 26 to move horizontally back and forth, which can drive the movable block 9 to move vertically back and forth in the inner cavity of the cooling water tank 8. And by opening through holes 31 in the movable block 9, it is convenient for the water flow or air flow to pass through the movable block 9 when the movable block 9 moves. Then, during the movement of the movable block 9, it will not drive the water flow in the inner cavity of the cooling water tank 8 in the movable mold 2 to move, but only stir the water flow, promote the heat exchange rate between the water flow in the inner cavity of the cooling water tank 8 and the water flow in the inner cavity of the condensate pipe 5, and improve the cooling effect on the mold product.

[0035] Since the cooling water tank 8 located in the inner cavity of the moving mold 2 is above the condensing pipe 5 and the inner cavity of the cooling water tank 8 is enclosed, the water flow in the condensing pipe 5 will not automatically enter the cooling water tank 8 in the inner cavity of the moving mold 2, which affects the cooling effect of the mold. To enable the water flow in the inner cavity of the condensing pipe 5 in the moving mold 2 to smoothly enter the cooling water tank 8, an air pipe 36 is fixedly connected to the upper end of the movable block 9. The lower end of the air pipe 36 passes through the outer shell 12 and enters the cavity 25. A connecting pipe 29 is fixedly connected to one side of the inner cavity of the cavity 25. A pneumatic pump 30 is fixedly connected to the middle of one side of the connecting pipe 29. The end of the air pipe 36 away from the movable block 9 is fixedly connected to the connecting pipe 29. By turning on the pneumatic pump 30, the gas in the inner cavity of the cooling water tank 8 can be pumped away through the connecting pipe 29 and the air pipe 36, thereby forming a negative pressure in the inner cavity of the cooling water tank 8, and then promoting the water flow in the condensing pipe 5 to enter the inner cavity of the cooling water tank 8 through the sleeve 10, so as to facilitate the cooling treatment of the injection molded product.

[0036] Please refer to Figure 10 , the lower end of the movable block 9 is elastically connected with a sliding rod 33. The lower ends of the symmetric sliding rods 33 are fixedly connected together with a floating plate 34. The floating plate 34 is circular, and the diameter of its inner cavity is larger than the outer diameter of the inner rod 17, so that the floating plate 34 is elastically connected with the movable block 9. The upper end of the floating plate 34 is fixedly connected with symmetric blocking plates 32. The position and size of the blocking plates 32 correspond to the through holes 31. The upper end surface of the air pipe 36 is lower than the upper end surface of the height increasing ring. And during the process of the pneumatic pump 30 pumping air through the air pipe 36, the air flow in the inner cavity of the cooling water tank 8 will enter the air pipe 36 through the through holes 31. The water flow will gradually enter the cooling water tank 8 from the condensing pipe 5. During the upward movement of the water flow, the water flow will gradually approach the floating plate 34 and push the floating plate 34 closer to the position where the movable block 9 is located, so that the blocking plate 32 gradually approaches the through hole 31. When the blocking plate 32 enters the inner cavity of the through hole 31, the blocking plate 32 blocks the through hole 31. Then at this time, the air flow will no longer enter the air pipe 36 through the through hole 31, thereby preventing the water flow from entering the air pipe 36 through the through hole 31. When the pneumatic pump 30 blows air into the inner cavity of the cooling water tank 8 through the air pipe 36, at this time the air flow will push the water flow in the inner cavity of the cooling water tank 8 back into the condensing pipe 5 again, so as to continuously pump air and blow air to complete the entry or exit of the water flow in the condensing pipe 5 into or out of the inner cavity of the cooling water tank 8, thereby completing the cooling of the product. At the same time, it is convenient to continuously replace the water flow in the cooling water tank 8 to ensure the cooling effect, ensure the quality of the product while passing the cooling rate of the product, and the floating plate 34, the blocking plate 32, the air pipe 36, the connecting pipe 29 and the pneumatic pump 30 are all arranged only in the outer shell 12 located in the fixed mold 1.
