RESIN MOLD

摘要

PROBLEM TO BE SOLVED: To achieve the reduction of a mold manufacturing time and cost and the increase of the proportion of the general-purpose member in a resin mold which have been incapable heretofore in conventional technique by performing independent replacement of a cavity unit by further finely dividing the members constituting a chase. SOLUTION: This mold is constituted so that a chase 7 is detachably supported on a mold base 18. In this case, a cavity unit consisting of a cavity body 2 having a cavity 1 for molding a resin mold formed thereto and an ejector plate 4 is detachably supported on the chase 7 and the center unit 6 for driving the ejector plate 4 is disposed between the chase 7 and the mold base 18. The center unit 6 is driven by the ejector unit 14 disposed in the mold base 18.
