PROBLEM TO BE SOLVED: To provide a low cost press device capable of cooling a mold efficiently.SOLUTION: First and second annular cooling bodies 7 and 8 having flow passages 7a and 8a, in which water can flow, are so mounted that they individually contact over the whole areas of the outer circumferences of an upper die 6 and a lower die 5. To the first and second annular cooing bodies 7 and 8, there is connected a pump 12 for circulating water in the flow passages 7a and 8a to perform heat exchange with a mold 4.SELECTED DRAWING: Figure 1 |
