Patent ID: 7186106

Claim:
A molding machine comprising: a fixed platen which is disposed at one end of a base plate and which supports a fixed die; a movable platen which supports a movable die; a supporting mount which supports respective end portions of four tie bars which are inserted through the movable platen; the movable platen and the supporting mount being disposed on the front and rear of the base plate so as to be capable of advancing/retreating with respect to the fixed platen, die opening/closing means which causes the movable platen and the supporting mount to advance/retreat so as to carry out die opening/closing by the movable die in relation to the fixed die, and which causes the supporting mount to retreat from the movable platen after opening the die; and a lock mechanism which is provided in the fixed platen, and which, in relation to the fixed platen, locks/unlocks the other end portion of each tie bar which is inserted in the fixed platen when closing the die; and die clamping means which is disposed between the movable platen and the supporting mount, and which causes the movable platen to travel toward the fixed platen side in a die closed state so as to generate a clamping force between the fixed die and the movable die.
