Abstract

The present invention provides a rotary compression molding machine capable of efficiently manufacturing small batches of compression molded products of various types. It is equipped with an operating mechanism for selectively operating a plurality of lower pestles to be fixed at the top dead center regardless of the revolution of the lower pestle, and to be able to move up and down according to the revolution of the lower pestle. . The operating mechanism is, for example, an operating member provided corresponding to each of the plurality of lower punches. The operating member can take a fixed position where it engages with the corresponding lower pestle to fix the lower pestle at the top dead center, and an operating position where it disengages the lower pestle.

Description

technical field [0001] The present invention relates to a rotary compression molding machine for compression molding a material to be molded such as powder. Background technique [0002] A rotary compression molding machine comprising a rotating body that is horizontally driven around a vertical rotation axis and has a plurality of sockets in the circumferential direction, and an upper punch that is movably inserted up and down from the upper and lower openings of the sockets, respectively. The upper and lower punches are used in various fields such as the molding of epoxy resin for sealing semiconductors by compressing and molding the material to be molded such as powder filled in the aforementioned socket. [0003] However, the conventional rotary compression molding machine has the problem of being unsuitable for the production of small quantities of multiple shapes because the existing socket, upper punch, and lower punch have to be replaced when the outer diameter of th...
