DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] The present invention proposes a cooling device for casting and molding cast iron pipe fittings, comprising; Workbench 1; The inner shell 2 is arranged above the workbench 1; A bearing block is fixedly mounted on the upper end surface of the workbench 1, and one end of the bearing block is fixedly connected to the outer wall surface of the inner shell 2, so that the inner shell 2 and the workbench 1 can be relatively fixed; The outer shell 3 is a pair, both of which are arranged on the outer surface of the inner shell 2, and the pair of outer shells 3 are merged; The upper ends of the pair of outer shells 3 are respectively formed with arc grooves, and the pair of arc grooves are merged with each other, which can facilitate the staff to pour the molten iron to the outside of the pair of outer shells 3 and be located outside the inner shell 2, so as to facilitate the molding; A cooling cavity 4 is formed in the side wall of the outer shell 3; The water inlet pipe 5 is fixedly mounted on the outer surface of the outer shell 3 and communicated with the cooling chamber 4; A pair of water inlet pipes 5 are metal hoses; The heat dissipation fins 6 are arranged on the upper end surface of the workbench 1; A four-way connector 7 is provided on the upper end surface of the workbench 1, and the four ends thereof are respectively connected with the water outlet end of the heat dissipation fin 6, the inner shell 2 and one end of a pair of water inlet pipes 5; A cooling water delivery mechanism is provided on the upper end surface of the workbench 1 and is used to deliver cooling water to the heat dissipation fins 6; The cooling water delivery mechanism can deliver external cooling water to the heat dissipating fins 6, and then flow from the water outlet end of the heat dissipating fins 6 to the four-way connector 7. At this time, the remaining three ends of the four-way connector 7 are respectively delivered to the inner shell 2 and a pair of water inlet pipes 5. At this time, the cooling water in the pair of water inlet pipes 5 flows into a pair of cooling boxes 4, which can cool the poured molten iron and make it quickly take shape.

[0018] Specifically, the cooling water delivery mechanism includes: A water tank 8 is arranged on the upper end surface of the workbench 1; The water tank 8 is fixedly mounted on the upper end surface of the workbench 1 and can be kept fixed. At the same time, a water filling port is provided on the water tank 8, which can facilitate the staff to add cooling water into the water tank 8; A self-priming pump 9 is arranged on the upper end surface of the workbench 1, and the water outlet end is connected with the water inlet end of the heat dissipation fin 6, and the water inlet end is connected with the water tank 8; The self-priming pump 9 is fixedly mounted on the upper end surface of the workbench 1 and can be kept fixed. At the same time, the self-priming pump 9 can pump the cooling water in the water tank 8 into the heat dissipation fins 6, so that the heat dissipation fins 6 can dissipate heat and cool the cooling water; A U-shaped tube 10 is disposed on the upper end surface of the workbench 1, and the U-shaped tube 10 is connected to the water tank 8; A water outlet pipe 11, one end of which is connected to one end of the U-shaped pipe 10, and the other end of which is fixedly connected to the upper end of the outer surface of the outer shell 3 and connected to the cooling chamber 4; A fixed tube 12, one end of which is connected to the U-shaped tube 10, and the other end of which is connected to the inner shell 2; The pair of water outlet pipes 11 are metal hoses. The cooling water in the inner shell 2 and the pair of cooling chambers 4 can flow into the U-shaped tube 10 through the pair of water outlet pipes 11 and the fixed tube 12 respectively, and then flow into the water tank 8 through the U-shaped tube 10.

[0019] Specifically, a partition plate 13 is fixedly installed in the inner shell 2, and a through hole 14 is formed on one side of the partition plate 13; The partition 13 can divide the inner space of the inner shell 2 into two spaces. At this time, the water flowing out from one end of the four-way connector 7 can first flow to the bottom of the partition 13. When the cooling water fills the space below the partition 13, the cooling water flows from the through hole 14 to the space above the partition 13 to cool the inner shell 2. After it is filled, it flows out from the fixing rod 12.

[0020] Specifically, two pairs of slide grooves 15 are formed on the upper end surface of the workbench 1, and a pair of sliders 16 are fixedly installed on the outer surface of the outer shell 3, and the sliders 16 are slidably connected with the slide grooves 15; A connecting plate 17 is fixedly installed between a pair of sliders 16. A pair of cylinders 18 are fixedly mounted on the upper end surface of the workbench 1, and the telescopic ends of the cylinders 18 are fixedly connected to one end surface of the connecting plate 17; The contraction of the telescopic ends of a pair of cylinders 18 can drive a pair of connecting plates 17 to move away from each other. At this time, the pair of connecting plates 17 can drive two pairs of sliders 16 to slide in two pairs of slide grooves 15 respectively. At this time, the sliding of the two pairs of sliders 16 can drive a pair of outer shells 3 to move away from each other, and the inner shell 2 can be opened, making it convenient for the staff to remove the formed pipe fittings on the outer surface of the inner shell 2.

[0021] Specifically, a cooling fan 19 is fixedly mounted on the outer surface of the cooling fin 6; The staff drives the cooling fan 19, and the cooling fan 19 can blow on one end surface of the cooling fin 6, so as to improve the heat dissipation efficiency of the cooling fin 6 to the cooling water.

[0022] Specifically, a limiting groove 20 is formed on one end surface of one outer shell 3, and a limiting rod 21 plugged into the limiting groove 20 is fixedly installed on one end surface of the other outer shell 3; The limiting rod 21 is plugged into the limiting groove 20, so that the position of the pair of outer shells 3 when combined can be limited, making the combination more stable.

[0023] Working principle: First, the staff applies lubricating oil to the inner surface of a pair of outer shells 3 and the outer surface of the inner shell 2, and starts a pair of cylinders 18 at the same time. The extension of the telescopic ends of the pair of cylinders 18 can drive a pair of connecting plates 17 to approach each other. At this time, the pair of connecting plates 17 can drive two pairs of sliders 16 to slide in two pairs of slide grooves 15 respectively. At this time, the sliding of the two pairs of sliders 16 can drive a pair of outer shells 3 to approach each other and merge, and the limit rod 21 is inserted into the limit groove 20, so that the outer surface of the inner shell 2 can be wrapped. At this time, a pair of arc grooves are used to pour molten iron into a pair of outer shells 3. After the pouring is completed, the staff starts the heat dissipation. The fan 19 and the self-priming pump 9 can pump the cooling water in the water tank 8 into the radiating fins 6, so that the radiating fins 6 dissipate heat and cool down the cooling water. After heat dissipation and cooling, the cooling water flows from the outlet end of the radiating fins 6 to the four-way connector 7, and then flows from the four-way connector 7 to the inner shell 2 and a pair of water inlet pipes 5 respectively. At this time, the cooling water in the pair of water inlet pipes 5 can flow into a pair of cooling chambers 4 respectively. The cooling water in the cooling chamber 4 can cool down the outer shell 3, so that the outer shell 3 can cool down the molten iron in contact with it. At this time, after the cooling water in the cooling chamber 4 is filled, the outlet pipe 11 flows into the U-shaped tube 10. At the same time, the water flowing from the four-way connector 7 into the inner shell 2 first fills the space below the partition 13, and then flows from the through hole 14 to the space above the partition 13 after filling. When the space above the partition 13 is filled, it flows from the fixed pipe 12 to the U-shaped tube 10. At this time, the cooling water in the U-shaped tube 10 flows into the vertical 8. While the self-priming pump 9 continuously pumps the water in the water tank 8, the outer shell 3 and the inner shell 2 can be cyclically cooled, so that the cast molten iron can be quickly cooled and formed as soon as possible. After the forming is completed, the self-priming pump 9 is turned off, and a pair of cylinders 18 are started at the same time. The contraction of the telescopic ends of the pair of cylinders 18 can drive a pair of connecting plates 17 to move away from each other. At this time, the pair of connecting plates 17 can drive two pairs of sliders 16 to slide in two pairs of slide grooves 15 respectively. At this time, the sliding of the two pairs of sliders 16 can drive a pair of outer shells 3 to move away from each other, and the inner shell 2 can be opened, so that the staff can remove the formed pipe fittings on the outer surface of the inner shell 2, which brings convenience to people.
