Drawings

FIG. 1 is a schematic cross-sectional view of an embodiment of the present invention;

fig. 2 is a partially enlarged view of a portion a in fig. 1.

Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means, and to fully understand and implement the technical effects of the present invention.

Examples

Referring to fig. 1 and 2, a take liquid nitrogen refrigerated aluminium alloy mould, include frame 1, extrusion die mechanism 2, rack-mounted liquid nitrogen jar 3, output hose 31 and be located the shower nozzle 4 of output hose 31 free end, extrusion die mechanism 2 locates on frame 1, and mould body 5 of compriseing last mould 51, lower mould 52 is installed to its output, mould pad 6 is installed to mould body 5 and the relative one side of extrusion die mechanism 2, annular cooling ring groove 61 has been seted up at the center of mould pad 6, and the outside of mould pad 6 is equipped with the support piece that is used for fixed mould pad 6 and mould body 5, mould body 5 and the upper and lower both ends of mould pad 6 are fixed with lower fixed plate 8 through upper fixed plate 7 respectively, an embedding hole 71 that is used for installing shower nozzle 4 has been seted up on upper fixed plate 7, embedding hole 71 lower extreme opening with mould pad 6, A through groove 9 is formed by communicating gaps between the mold bodies 5, the through groove 9 is communicated with the cooling ring groove 61, a fixing seat 72 is arranged outside the upper fixing plate 7 at the periphery of the embedding hole 71, the spray head 4 is arranged in the fixing seat 72 in a penetrating manner, a clamping block 41 is arranged on the spray head 4, and a spring 73 is arranged outside the spray head 4 between the clamping block 41 and the fixing seat 72.
