Description

Technical Field

[0001] This utility model relates to the field of mold cooling, and in particular to a novel rapid mold cooling device. Background Technology

[0002] A novel rapid cooling device for molds is a device used to achieve rapid cooling during mold processing. It typically utilizes an efficient cooling medium circulation system to reduce the mold temperature. The cooling medium, such as water, oil, or a special coolant, circulates within the device and rapidly removes heat from the mold through heat exchange. Some advanced cooling devices may also employ special cooling structure designs, such as optimized layout of internal cooling channels, to improve cooling efficiency.

[0003] In existing technologies, some mold cooling devices only cool certain areas of the mold, which can lead to significant temperature differences between different parts of the mold. This can result in uneven shrinkage stress in the product during the cooling process, causing defects such as warping and deformation. It can also generate residual stress inside the mold, affecting the product's strength, toughness, and other performance indicators. Therefore, a new type of rapid mold cooling device is proposed to solve the above problems. Utility Model Content

[0030] 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.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of a novel mold rapid cooling device, comprising a connecting block 1, a cylinder 2 fixedly connected to the outer top of the connecting block 1, a fixed column 3 slidably connected to the inner bottom of the connecting block 1, a connecting plate 4 fixedly connected to the bottom of the fixed column 3, and multiple telescopic rods 5 fixedly connected to the outer bottom of the connecting plate 4. During the operation of the device, the telescopic rods 5 can be flexibly extended and retracted according to the height of different molds and cooling requirements, thereby precisely controlling the position of the sealing cover 8 and the degree of fit with the mold. The setting of multiple telescopic rods 5 ensures the stability and parallelism of the sealing cover 8 during the descent and ascent, preventing the sealing cover 8 from tilting or shaking, and ensuring the uniformity and reliability of the cooling effect.

[0032] A liquid nitrogen tank 6 is fixedly connected to the outer top of the connecting block 1. A bellows 7 is fixedly connected to the outside of the liquid nitrogen tank 6. During the operation of the device, the bellows 7 can freely extend and retract with the extension and retraction of the telescopic rod 5 and the movement of the sealing cover 8, ensuring that liquid nitrogen can be smoothly transported from the liquid nitrogen tank 6 to the cooling plate 9 inside the sealing cover 8. The bellows 7 has good sealing performance and can effectively prevent liquid nitrogen leakage, ensuring the safe operation of the device. A sealing cover 8 is fixedly connected to the outer bottom of multiple telescopic rods 5. During the operation of the device, the sealing cover 8 can accurately descend under the drive of the telescopic rods 5 and tightly cover the mold, forming a cooling space.

[0033] The outer bottom end of the bellows 7 is fixedly connected to the inner top end of the sealing cover 8. The outer side of the bellows 7 is slidably connected to the inside of the connecting block 1. Cooling plates 9 are fixedly connected to both sides of the inner wall of the sealing cover 8, which can quickly transfer the low temperature of liquid nitrogen to the mold to achieve a rapid cooling effect. A sealing ring 10 is fixedly connected to the outer bottom end of the sealing cover 8. Multiple support columns 11 are fixedly connected to the outer bottom end of the connecting block 1. Support blocks 12 are fixedly connected to the bottom ends of the multiple support columns 11. Portable components for movement are fixedly connected to the bottom ends of the support blocks 12.

[0034] Reference Figure 2 , Figure 4The outer top of the support block 12 is fixedly connected to the demolding box 13. The inside of the demolding box 13 is slidably connected to the tray 14. The bottom of the inside of the demolding box 13 is slidably connected to the sliding block 15. The outside of the sliding block 15 is slidably connected to the sliding block 16. The sliding block 16 is slidably connected inside the demolding box 13. The inside of the sliding block 16 is slidably connected to the connecting rod 17. The top of the inside of the demolding box 13 is fixedly connected to the fixing block 18. The outer top of the connecting rod 17 is fixedly connected to the bottom of the inside of the fixing block 18. The inside of the fixing block 18 is fixedly connected to the fixing rod 19. The inside of the fixing rod 19 is slidably connected to the sliding rod 20. The outside of the sliding block 16 is in contact with the bottom of the outside of the sliding rod 20. The movement of the sliding block 16 can push the sliding rod 20 to move upward, thereby causing the tray 14 to rise.

[0035] A spring 21 is fixedly connected to the outside of the sliding rod 20, and a baffle 22 is also fixedly connected to the outside of the sliding rod 20. The baffle 22 slides inside the fixed rod 19 as the sliding rod 20 moves, which limits the stroke of the spring 21 and prevents the sliding rod 20 from moving excessively. When the spring 21 is compressed, the baffle 22 can prevent the sliding rod 20 from moving excessively upward, ensuring the safety and stability of the demolding operation. The top end of the spring 21 is fixedly connected to the inside top end of the fixed rod 19, and the bottom end of the spring 21 is fixedly connected to the outside top end of the baffle 22. The outside of the baffle 22 is slidably connected to the inside of the fixed rod 19. A support plate 14 is fixedly connected to the top end of the sliding rod 20. The sealing ring 10 plays a sealing role to prevent the cooling medium from leaking. During the rising process, the support plate 14 is in close contact with the sealing ring 10, ensuring the sealing of the cooling space and improving the cooling effect and the safety of demolding.

[0036] The outer bottom end of the sealing ring 10 contacts the outer top end of the tray 14. The outer side of the tray 14 is slidably connected to the inside of the demolding box 13. An electric push rod 23 is fixedly connected to the outer bottom end of the demolding box 13. The portable component includes a fixing plate 24. The outer top end of the fixing plate 24 is fixedly connected to the outer bottom end of the support block 12. Multiple casters 25 are fixedly connected to the outer bottom end of the fixing plate 24.

[0037] Working principle: First, cylinder 2 is activated. The drive end of cylinder 2 moves the fixed column 3 downward, which in turn moves the connecting plate 4 downward, then the telescopic rod 5, and finally the sealing cover 8. The processed mold is supplied with liquid nitrogen through the liquid nitrogen tank 6 to the bellows 7, which then delivers it to the inner wall of the sealing cover 8. This liquid nitrogen, in conjunction with the cooling plate 9, cools the mold. The sealing ring 10 seals the liquid nitrogen within the inner wall of the sealing cover 8, ensuring comprehensive cooling. After cooling, cylinder 2 retracts, causing the connecting plate 4 to retract upward, which in turn retracts the telescopic rod 5, causing the sealing cover 8 to retract upward.

[0038] After cooling, the electric push rod 23 is activated. The drive end of the electric push rod 23 pushes the sliding block 15 to slide, which in turn drives the sliding block 26 to slide in the movement groove of the sliding block 15. Then, the sliding block 26 slides along the trajectory of the connecting rod 17, and then the sliding block 26 contacts the bottom end of the fixed block 18, which in turn pushes the sliding rod 20 to slide. When the sliding rod 20 slides, the baffle 22 limits the sliding rod 20, which in turn drives the support plate 14 to push upward, and demolds the mold after cooling.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
