PURPOSE:To automate separation of a mold after molding is completed, by attaching one specific vibrating lever to a press molding apparatus for press- molding a rubber material. CONSTITUTION:When a pushing-up member 6 and 25 is moved upward, each guide member 8 and 26 is moved upward while being kept in horizontal state. Mold platens 4a and 4b are separated from a bottom force platen 4c while being kept in horizontal state. Further upward movement is continued, the pushing-up member 25 is inclined in centering around a roller 28 and comes eventually into a vertical state where a top force platen 4a of the mold platen is in an open state to the bottom force platen 4c by 90 deg., and the middle force platen 4b is in an open state to the bottom force platen 4c by 60 deg.. Before the top force platen 4a takes a vertical position, a nail member 33 is worked and the top force platen 4a is thereby pinched and fixed on a guide member 26 and positional deviation between the guide member 26 and the top force platen 4a is prevented. These serial movements are done by the vibrational movement of a common vibrational lever 10. |
