Patent ID: 8342837

Claim:
A resin sealing apparatus comprising a first mold, and a second mold that can be brought into and released from contact with the first mold, wherein at least one substrate provided in both the molds and mounted with electronic components is subjected to resin sealing and molding by filling with molten resin material of cavities formed by both the molds, the second mold placed on a base plate so as to be capable of horizontally reciprocating, and comprising a cavity block that can be brought into and released from contact with the first mold and that is a part of the area opposed to the first mold, containing the cavity, and a mold clamping mechanism that brings and releases the cavity block into and from contact with the first mold so as to perform mold clamping, the base plate provided with a horizontal actuation mechanism for moving the second mold to a facing position where the second mold faces the first mold and to a non-facing position where the second mold has been moved sideways from the facing position, wherein the base plate comprises a vertical actuation mechanism that actuates the cavity block independently from the mold clamping mechanism so as to bring and release the cavity block into and from contact with the first mold at speeds higher than the mold clamping mechanism, and wherein the vertical actuation mechanism and the second mold comprise joints that become linked status in the facing position and that become unlinked status in the non-facing position.
