发明名称 OUTER PERIPHERY HOLDING STRUCTURE OF DISK MOLDING STAMPER
摘要 PURPOSE:To reduce labor at exchanging a stamper and improve safety. CONSTITUTION:An outer periphery pressing member 18 for holding an outer periphery of a stamper serves also as a spacer between dies, and is constituted of a ring member 20 for sealing an outer peripheral area of a cavity and a stamper holder 22 integrally formed on the inner periphery of the ring member 20. On both sides of the ring member 20, tapped holes 20a are formed so as to be optionally attached exchangeably to either a fixed side mold 4 or a moving side mold 6 by a through bolt 24 as an attachment exchange member which passes through the fixed side mold 4 or the moving side mold 6, without requiring manual holding operation.
