Through the arrangement of the first upper clamping die 101, the second upper clamping die 103 and the lower cover plate 109, the cooling die 100 can be quickly disassembled and assembled. Meanwhile, a cavity 104 formed between the first upper die assembly 101 and the second upper die assembly 103 can be directly used for containing molten metal to be cooled, and when the molten metal is completely contained and is not solidified, the whole die is rapidly immersed into cooling media such as water and liquid nitrogen, so that rapid cooling can be realized.

Preferably, in this embodiment, the first fastening member 115 may be a fastening bolt, and the first upper mold 101 and the second upper mold 103 are detachably connected by the fastening bolt. The first upper die 101 and the second upper die 103 are connected through the fastening bolts, so that the first upper die and the second upper die can be conveniently disassembled and assembled, and can be simply matched in the using process, and the working efficiency can be effectively improved. In the present embodiment, the number of the fastening bolts is four, and the fastening bolts are arranged in a rectangular array on the first upper mold 101 and the second upper mold 103, and pass through the inner contact smooth folding surfaces of the first upper mold 101 and the second upper mold 103 perpendicular to the bolt axial direction. Through the arrangement of the fastening bolts arranged in the four arrays, after the first upper die assembly 101 and the second upper die assembly 103 are connected, the fastening force is distributed uniformly and stably, and the sealing performance is improved.

Referring to fig. 1 to 3 again, in the present embodiment, the sum of the total depths of two annular knife-edge grooves 111 formed on the contact surfaces of the lower cover plate 109 and the first upper mold half 101 and the second upper mold half 103 is greater than the thickness of the gasket 113. The arrangement is such that the two annular knife-edge recesses 111 can completely accommodate the washer 113, the assembly is convenient, and the accommodation requirement can be met when the washer 113 is plastically deformed under the fastening action of the second fastening member 117. It should be noted that the annular knife-edge groove 111 is arranged coaxially with the cavity 104. An annular knife edge groove 111 is formed in two contact surfaces of the first upper die 101, the second upper die 103 and the lower cover plate 109, and the gasket 113 is pressed through the annular knife edge groove 111, so that a sealing structure similar to an ultrahigh vacuum sealing structure can be formed to reach a sealing standard, and the sealing performance of the assembled die in a cooling medium can be guaranteed.

The depth of the single annular knife edge groove 111 is 1.7mm, and the vertical distance between the knife tip of the annular knife edge groove 111 and the contact surface is 0.5 mm. The thickness of the gasket 113 is 2 mm. By limiting the slope and back of the annular knife-edge groove 111 and the depth, the gasket 113 can be tightly fitted with the annular knife-edge groove 111 under the compression of the second fastener 117, thereby providing good sealing performance. Of course, in other embodiments of the present invention, various parameters of the annular knife-edge groove 111 may be adjusted according to requirements, and the present invention is not limited thereto.

Of course, in other embodiments of the present invention, the number of the second fastening members 117 is not limited to six, and may be more or less, so as to provide good sealing performance, and the embodiments of the present invention are not limited thereto.
In the present embodiment, the hardness of the material of the first upper mold 101, the second upper mold 103, and the lower cover plate 109 is higher than the hardness of the gasket 113. This is designed so that the washer 113 can be plastically deformed by the fastening action of the second fastening member 117.
Alternatively, the material of the first upper clamping die 101, the second upper clamping die 103 and the lower cover plate 109 is austenitic chromium nickel stainless steel 310S, the gasket 113 is a copper gasket, and the material of the copper gasket is 1/4 hard oxygen-free copper OFHC. The steel material of the die can meet the requirement of sufficient heat conduction while providing sufficient hardness, and the heat conduction efficiency is improved. On the one hand, the copper gasket can ensure that the copper gasket can provide a normal use function under the heating condition when being acted by a molten metal medium, on the other hand, the hardness of the copper gasket is smaller than that of austenitic chromium nickel stainless steel 310S, and the copper gasket can generate plastic deformation under the fastening force action of the second fastening piece 117, so that the processing defects and tiny gaps of the annular knife edge groove 111 are filled, and the sealing capability similar to a vacuum level is achieved. Of course, in other embodiments of the present invention, the materials of the gasket 113 and the mold may also be selected according to the requirement, and the embodiments of the present invention are not limited.
