The copper inner cylinder 2 is cooled quickly by water cooling to ensure rapid solidification of the casting. The copper inner cylinder 2 is in direct contact with the high-temperature molten metal. The high thermal conductivity of copper is used to quickly transfer heat to the inside of the stainless steel outer water-cooling jacket 1. At the same time, the split design facilitates disassembly and replacement, solving the problem of being unable to repair after the one-piece mold is damaged.

A support pad 53 is provided on one side of the copper heat-conducting column 52, and the support pad 53 supports the sealing ring 42.

The sealing ring 42 expands and moves with the inner copper cylinder 2, dynamically maintaining the sealing pressure. The limiting sealing mechanism 4 also includes a connecting frame 47 set on the surface of the stainless steel outer water cooling jacket 1. The connecting frame 47 is fixedly connected to the fixed shell 43. A flange 48 is fixedly connected to one side of the sealing ring 42. The flange 48 is fixedly connected to the movable plate 45 by a third bolt. The flange 48 fixes the position of the sealing ring 42 and enhances the overall stability of the structure. A base 6 is fixedly connected to the bottom of the connecting frame 47 by a second bolt. The top of the copper heat-conducting plate 51 is fixedly connected to the copper cover 3. A copper heat-conducting column 52 is fitted with a... The base 6 has an elastic sealing gasket 41, and a copper heat-conducting column 52 extends through to the bottom. A groove matching the elastic sealing gasket 41 is provided on the top of the base 6. The elastic sealing gasket 41 is in close contact with the base 6 to ensure its airtightness. The bottom of the support pad 53 is fixedly connected to the base 6. The base 6 integrates a coolant channel. The first and second bolts allow for the disassembly of components such as the copper heat-conducting plate 51 and the connecting bracket 47, facilitating maintenance or replacement of damaged parts. A water inlet pipe 7 is connected to one side of the base 6, and a first connecting pipe 8 is connected to the other side. A second connecting pipe 8 is connected to one side of the stainless steel outer water-cooling jacket 1. Connecting pipe 9, the other side of the stainless steel outer water cooling jacket 1 is connected to drain pipe 10, the surface of water inlet pipe 7, first connecting pipe 8, second connecting pipe 9 and drain pipe 10 are all provided with connecting threads, water inlet pipe 7, first connecting pipe 8, second connecting pipe 9 and drain pipe 10 form a coolant circulation path, water inlet pipe 7 injects coolant, drain pipe 10 discharges hot water, spring 46 is sleeved on the surface of guide rod 44, spring 46 is fixedly connected to fixed shell 43, elastic sealing gasket 41 and sealing ring 42 are in close contact with copper inner cylinder 2, and the top of support pad 53 is in contact with sealing ring 42.

[0029] The working principle of this utility model is as follows: The copper inner cylinder 2 is installed inside the stainless steel outer water-cooling jacket 1. A tight seal between the copper inner cylinder 2 and the stainless steel outer water-cooling jacket 1 is achieved through the elastic sealing gasket 41 and sealing ring 42 of the limiting sealing mechanism 4. The copper heat-conducting plate 51 of the support mechanism 5 is fixedly connected to the copper cover 3, and the support pad 53 contacts the sealing ring 42 to enhance stability. Coolant is injected into the base 6 from the inlet pipe 7, flows through the first connecting pipe 8 and the second connecting pipe 9 into the stainless steel outer water-cooling jacket 1, and forms a circulation with the drain pipe 10. The coolant absorbs the heat transferred by the copper inner cylinder 2, accelerating the solidification of the casting.

[0030] After the high-temperature molten metal is injected into the copper inner cylinder 2, the inner cylinder 2 expands due to heat, compressing the elastic sealing gasket 41 and causing the sealing ring 42 to move. The spring 46 stretches accordingly to dynamically maintain the sealing pressure and prevent leakage. The heat from the copper cover 3 is evenly conducted to the copper heat-conducting column 52 through the copper heat-conducting plate 51, and then transferred to the coolant in the base 6. The stainless steel outer water-cooling jacket 1 simultaneously dissipates heat from the side wall of the copper inner cylinder 2 through water cooling, achieving all-round rapid cooling. After casting is completed, the sealing plate, copper inner cylinder 2, and other components can be removed to take out the casting. If a component is damaged, it can be replaced individually without discarding the entire mold, significantly reducing costs. Through the synergistic effect of the split structure, dynamic sealing, and efficient cooling system, the problems of difficult manufacturing and high maintenance costs of traditional one-piece molds are solved, while improving heat dissipation efficiency and casting quality, demonstrating significant practicality and economy.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
