Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] like Figures 1-4A rapid cooling device for casting molds includes an upper mold 1, a lower mold 2, a snap-fit ​​plate 4, a liquid inlet pipe 5, a locking buckle 1 6, a locking buckle 2 61, a cooling pipe 10, an upper connecting seat 11, a lower connecting seat 12, a diversion groove 13, and a drain pipe 15. The top of the upper mold 1 and the bottom of the lower mold 2 both have receiving grooves 23 for accommodating the snap-fit ​​plate 4 and the cooling pipe 10. The front and rear sides of the bottom of the upper mold 1 and the front and rear sides of the top of the lower mold 2 both have mounting grooves 24. The snap-fit ​​plate 4 has two parts, upper and lower, and includes a sealing plate 41 and elastic arc-shaped snap-fit ​​plates 42. The sealing plate 41 seals the receiving grooves 23. Four elastic arc-shaped snap-fit ​​plates 42 for accommodating the cooling pipe 10 are connected on the sealing plate 41 from left to right at intervals. Each elastic arc-shaped snap-fit ​​plate 42 contains a snap-fit ​​plate. A cooling pipe 10 is connected to the upper mold 1. Four locking clips 6 are installed circumferentially at intervals on the top of the upper mold 1 and the bottom of the lower mold 2. The male clip of the locking clip 6 is connected to the sealing plate 41, the female clip of the upper locking clip 6 is connected to the top of the upper mold 1, and the female clip of the lower locking clip 6 is connected to the bottom of the lower mold 2. The upper and lower snap-fit ​​plates 4 are locked to the upper mold 1 and the lower mold 2 respectively by the locking clips 6. The locking clips are existing technology and will not be described in detail here. A diversion groove 13 located outside the elastic arc-shaped snap-fit ​​plate 42 is connected to the sealing plate 41 of the snap-fit ​​plate 4. Four insertion holes for the liquid inlet end of the cooling pipe 10 are spaced apart from left to right at the bottom and top of the upper and lower diversion grooves 13. The cooling pipe 10 consists of a vertical pipe and a U-shaped pipe. The U-shaped pipe is snapped into the elastic arc-shaped snap-fit ​​plate 42. Inside the clamping plate 42, a vertical tube is connected to the middle of the U-shaped tube. The liquid inlet end of the vertical tube slides through the elastic arc-shaped clamping plate 42 and is inserted into the insertion hole to communicate with the diversion groove 13. The top middle of the upper diversion groove 13 and the bottom middle of the lower diversion groove 13 are both connected to the liquid inlet pipe 5, which extends to the outside of the sealing plate 41. The mounting groove 24 of the upper mold 1 is provided with an upper connecting seat 11, which is inserted into the liquid outlet end of the upper cooling pipe 10. This allows the upper connecting seat 11 and the upper cooling pipe 10 to be easily and quickly disassembled and reinstalled when maintenance or replacement is required, thereby improving the convenience and efficiency of maintenance and replacement of the upper connecting seat 11 and the upper cooling pipe 10. The mounting groove 24 of the lower mold 2 is provided with a lower connecting seat 12, which is connected to the upper... The connector 11 and the outlet end of the lower cooling pipe 10 are connected by insertion, allowing for convenient and quick disassembly and reinstallation of the lower connector 12 and the lower cooling pipe 10 when maintenance or replacement is required. This improves the ease and efficiency of maintenance and replacement of the lower connector 12 and the lower cooling pipe 10. Sealing rings are connected to both the inlet and outlet ends of the cooling pipe 10. These sealing rings fill the tiny gaps between the cooling pipe 10 and its connecting parts, effectively preventing coolant leakage. Two locking buckles 61 are installed in the mounting groove 24. The male buckle of the upper locking buckle 61 connects to the mounting groove 24 of the upper mold 1, and the female buckle of the upper locking buckle 61 connects to the upper connector 11. The male buckle of the lower locking buckle 61 connects to the mounting groove 24 of the lower mold 2.The female buckle of the lower locking latch 61 is connected to the lower connecting seat 12. The upper connecting seat 11 and the lower connecting seat 12 are locked in the mounting groove 24 by the locking latch 61. A drain pipe 15 extending to the outside of the upper mold 1 is connected to the upper connecting seat 11.

[0027] First, connect the inlet pipe 5 to the external liquid delivery equipment, and then connect the outlet pipe 15 to the external liquid extraction equipment. When the upper mold 1 moves down to close with the lower mold 2, it drives the upper connecting seat 11 to move down and insert into the lower connecting seat 12. At this time, the lower cooling pipe 10 is connected to the upper connecting seat 11 through the lower connecting seat 12. When it is necessary to cool the upper mold 1 and the lower mold 2, control the operation of the liquid delivery equipment to inject the coolant into the distribution tank 13 through the inlet pipe 5. The coolant then enters the cooling pipe 10, and the coolant in the cooling pipe 10 is discharged from the front and rear sides. The coolant in the upper cooling pipe 10 is discharged into the upper connecting seat 11, and the coolant in the lower cooling pipe 10 is discharged into the lower connecting seat 12, and then into the upper connecting seat 11. By controlling the operation of the liquid extraction device, the coolant in the upper connecting seat 11 is extracted through the drain pipe 15, allowing the coolant to circulate within the upper and lower cooling pipes 10, the upper connecting seat 11, and the lower connecting seat 12. This ensures uniform water cooling of the upper mold 1 and the lower mold 2, reducing the risk of uneven stress distribution, deformation, or cracking within the casting and improving cooling efficiency. After cooling is complete, the liquid delivery device is stopped, while the liquid extraction device continues to extract all the coolant from the upper and lower cooling pipes 10, the upper connecting seat 11, and the lower connecting seat 12 to prevent leakage after mold opening. Once all the coolant has been extracted, the liquid extraction device is stopped, and the upper mold 1 is moved upwards to detach from the lower mold 2 for subsequent workpiece removal.

[0028] By releasing the locking plate 4 from the latch 6, the locking plate 4 can be removed from the receiving groove 23. The upper cooling pipe 10 is then pulled off the upper connecting seat 11, and the lower cooling pipe 10 is pulled off the lower connecting seat 12. The cooling pipe 10 can then be removed from the elastic arc-shaped locking plate 42 for maintenance or replacement. The cooling pipe 10 is then pulled out from the insertion hole on the diversion groove 13. The cooling pipe 10 is then snapped back into the elastic arc-shaped locking plate 42, and the liquid inlet end of the vertical tube on the cooling pipe 10 is inserted into the insertion hole on the diversion groove 13, connecting with the diversion groove 13. The maintenance and replacement of the cooling pipe 10 is simple, convenient, time-saving, and labor-saving. Loosen the locking buckle 61 to release the upper connecting seat 11 and the lower connecting seat 12, allowing them to be removed from the mounting slot 24 for maintenance or replacement. After maintenance or replacement, lock the locking buckle 61 again to lock the upper connecting seat 11 and the lower connecting seat 12. The maintenance and replacement of the upper connecting seat 11 and the lower connecting seat 12 is simple, convenient, time-saving, and labor-saving. When the snap-fit ​​plate 4 is placed back into the receiving slot 23, the liquid outlets on both sides of the upper cooling pipe 10 are inserted into the two upper connecting seats 11, and the liquid outlets on both sides of the lower cooling pipe 10 are inserted into the two lower connecting seats 12. Thus, this device achieves the effect of ensuring cooling uniformity while facilitating the maintenance and replacement of cooling pipes.

[0029] See Figures 4-5 The top of the upper diversion channel 13 and the bottom of the lower diversion channel 13 are both connected to two circular channels 16. A guide rod 17 is connected inside each circular channel 16. A movable cylinder 18 is slidably connected to the guide rod 17. A spring 19 is fitted onto the guide rod 17, and both ends of the spring 19 are connected to the cylinder 18 and the circular channel 16 respectively. The cylinder 18 has circumferentially spaced openings for liquid flow. The bottom of the upper cylinder 18 and the top of the lower cylinder 18 are both open. The cylinders 18 are connected to the baffle plates 20 located in the diversion channel 13. The baffle plates 20 are made of foam material. The baffle plates 20 have openings spaced from left to right to allow liquid to flow. The bottom of the upper baffle plate 20 and the bottom of the lower baffle plate 20 are connected to four connecting pipes 21 spaced from left to right. The connecting pipes 21 are located in the insertion holes of the diversion channel 13. The connecting pipes 21 are matched with the liquid inlet end of the cooling pipe 10. The connecting pipes 21 have liquid inlets spaced circumferentially to allow liquid to flow into them.

[0030] Initially, under the pushing action of spring 19, the baffle plate 20 blocks the insertion hole of the distribution channel 13. The connecting pipe 21 is inserted into the insertion hole of the distribution channel 13. After the coolant is injected into the distribution channel 13 through the inlet pipe 5, the coolant does not immediately flow into the cooling pipe 10. When the distribution channel 13 is full of coolant, more coolant is injected. Under the pushing action of the coolant, the cylinder 18 enters the circular groove 16, compressing the spring 19, thereby moving the baffle plate 20 away from the cooling pipe 10. The connecting pipe 21 then moves away from the cooling pipe 10. Subsequently, the coolant can flow through the opening on the baffle plate 20 to the area of ​​the distribution channel 13 near the cooling pipe 10. The foam baffle plate 20, under the pushing action of the coolant in the area of ​​the distribution channel 13 near the cooling pipe 10, remains detached from the insertion hole of the distribution channel 13. The coolant then enters the connector 21 through the inlet, and then drains from the outlet of the connector 21 into the insertion hole of the distribution channel 13, before flowing into the cooling pipes 10. This ensures that the distribution channel 13 is filled with coolant before being distributed to the cooling pipes 10, thus guaranteeing a uniform supply of coolant to all cooling pipes 10 and further improving cooling uniformity. After the inlet pipe 5 stops filling, as the coolant in the distribution channel 13 near the cooling pipes 10 is gradually discharged, the spring 19 gradually returns to its original position, pushing the cylinder 18 out of the circular groove 16, thereby pushing the baffle plate 20 to move closer to the cooling pipes 10 to block the insertion hole of the distribution channel 13.

[0031] See Figure 3 and Figure 6 The upper mold 1 has a fan-cooled radiator 7 installed on its left side. Two upper air pipes 8 are symmetrically installed on the left side of the upper mold 1, and the upper air pipes 8 are connected to the fan-cooled radiator 7 and the receiving groove 23 of the upper mold 1. Two lower air pipes 9 are symmetrically installed on the left side of the lower mold 2, and the lower air pipes 9 are connected to the receiving groove 23 of the lower mold 2. After the mold is closed, the upper air pipes 8 are inserted into the air inlets of the lower air pipes 9. The upper air pipes 8 and lower air pipes 9 are L-shaped. The U-shaped tube of the cooling pipe 10 is fitted with a sliding sleeve from front to back. The outside of the sliding sleeve is connected to the heat dissipation fins 22. The heat dissipation fins 22 are fitted on the outside of the cooling pipe 10 by the sliding sleeve, so as to facilitate the disassembly and reinstallation of the cooling pipe 10 and the heat dissipation fins 22, thereby improving the convenience and efficiency of maintenance and replacement of the cooling pipe 10 and the heat dissipation fins 22.

[0032] When the upper mold 1 moves down to close with the lower mold 2, it causes the upper air duct 8 to move down and insert into the air inlet of the lower air duct 9. When cooling is required, the air-cooled radiator 7 is controlled to operate, inputting cold air into the upper air duct 8. The upper air duct 8 then inputs cold air into the receiving groove 23 of the upper mold 1 to cool the upper mold 1. The upper air duct 8 then inputs cold air into the lower air duct 9, which in turn inputs cold air into the receiving groove 23 of the lower mold 2 to cool the lower mold 2, thereby further improving cooling uniformity and efficiency. The heat dissipation fins 22 on the outside of the upper and lower cooling pipes 10 can dissipate heat from the upper mold 1 and the lower mold 2 respectively, thereby further improving cooling uniformity and efficiency.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
