s3: when die-casting, circulating pump (1107) start, circulating pump (1107) are through the low temperature condensate suction heliciform heat exchange tube (1104) inner chamber of pipeline with condensate tank (1108) inner chamber, cool down the air of shell (1101) inner chamber, make air discharge fan (1102) blow to the air of shaping groove body (1401) be the low temperature state, then low temperature condensate enters into cavity (1403) inner chamber through condensate pipeline (1105) and cools down shaping groove body (1401), then enter into condensate tank (1108) inner chamber through the pipeline backward flow and carry out cooling once more.
