Abstract
PURPOSE: To reduce the number of parts of the molding die and the number of processing steps and lower the cost of the mold by embedding an ejector pin in a cavity unit, in the mold die provided with a number of cavities.
CONSTITUTION: In a mold provided with cavities 2 corresponding to the outer contour of a molding for an IC element, for example, a runner block 5 is interposed in the intermediate in the longitudinal direction of upper and lower cavity units 3 and 4, and base units 8 and 9 holding the cavity units from both upper and lower sides, are provided. In the lower cavity 4, there is embedded the ejector pin 12 so that it can project into the cavity 2. For this reason, in the case of producing moldings of different kinds, parts to be replaced may be only those held between the upper and lower base units 3 and 4 such as runner block 5, ejector pin 12, ejector pin holder 14, ejector spring 15 and the like, and therefore the number of parts is reduced.
