摘要:
A method of ejecting a first molded article (102) from a first stack portion (110, 210, 310) of a first mold stack (106A, 206A, 306A). The method comprising the steps of holding a stripper plate (116) immobile with the first molded article (102A) in supporting contact therewith, and retracting an inner core (112) relative to the stripper sleeve (116).
摘要:
The present invention provides a ceramic green sheet with a thin flat plate shape obtained by molding and solidifying a ceramic slurry, which contains a ceramic powder, dispersion medium, and gelling agent, into a thin flat plate. The ceramic green sheet partially includes a body that is obtained by molding and solidifying a conductor paste, which becomes a conductor later, and the body is exposed on a part of each of the both surfaces of the sheet. Plural ceramic green sheets described above are produced. The plural ceramic green sheets are successively stacked and press-bonded in the thickness direction in such a manner that the bodies included in the respective sheets are connected to each other for all combinations of the adjacent two sheets. As a result, a ceramic green sheet laminate is formed, which includes one body that is obtained by connecting the bodies included in the respective sheets.
