RESIN SEALING DEVICE

PROBLEM TO BE SOLVED: To provide a resin sealing device, wherein an ejector pin and a body sealed with resin, do not core into contact regardless of the thickness of a frame. SOLUTION: A resin sealing device 21 has a movable die 22 and fixed die 23. The movable die 22 has a tubular recess part 24a, wherein a frame 29 mounting a body, which is sealed with resin can be movably coupled, a frame block 24, which is held so as to move back and forth, so as to face the fixing die 23, a frame holder 25 mounting the frame and an elastic body 26 inserted between the frame block 24 and a frame holder 25. The fixed die 23 has a cavity block 23, a drive pin 39, where the tip that appears and disappears at the edge part deviated from a cavity 34, an ejector pin 35, which is inserted so as to appear and disappear in the cavity, and and ejector plate 36, which is located at the back-surface side of the cavity block 33 and exposes and fixes the tips of both the drive pin 39 and the ejector pin 35.
