摘要： A die clamping apparatus including a movable plate which is in connection with a pushing-out pin which is projected from and retracted to a moving die and which is held movably with respect to a moving die plate, a clamp member for obtaining a constraint of the movable member, an air cylinder and a hook member. Only a movement of the movable member is constraint by the air cylinder with respect to the moving die plate when the latter is moved in a die opening direction from a die opening limit position, so that a resultant relative movement between the movable plate and the moving die plate, which causes the pushing-out pin to be projected from the moving die, resulting in a removal of a molded product, while the constraint of the movable member prevents the moving die plate from being moved in the die closing direction when the moving die plate in the die opening limit position is under non clamping condition.

摘要： A new clamping machine is disclosed, which can perform a straight-hydraulic mold clamping and a tie-bar drawing-out operation in a reduced working space, and enables a shortened mold exchanging time, by effecting retraction of a movable die plate and a tie-bar drawing-out operation simultaneously. In order to draw out tie bars 18 from a fixed die plate 10 only when molds are exchanged, annular pistons 36, which construct mold clamping cylinders in the fixed die plate, are provided. Abutting each piston, a pair of half nuts 48A, 48B are arranged and driven to engage with an engagement portion 18A provided at one end of each tie bar on the side of the fixed die plate, usually, other than during the drawing out operation. A relative position of each tie bar to the half nuts is set to be able to engage with the half nuts when a right end face of the tie bar contacts with the stopper plate 46. When pressure for clamping molds is increased during such engagement, the annular pistons are driven to transmit a force, for performing an initial operation, to the tie bars.

摘要： The present invention provides a die plate and a mold clamping apparatus equipped with the die plate for a die casting machine and so on capable of reducing dimensions of die length as small as possible.A fixed die plate FXPL and a moving die plate MVPL of a mold clamping apparatus on a base BS place a versatile main mold inside, respectively. A pair of insert dies FINS and MINS is carried in to a mold opened space without disturbing tie bars TBU or TBD located in an upper portion or a side portion. The pair of insert dies are separated and fastened to each of the versatile main mold. The die length becomes zero or very small when the moving die plate positions at a mold closing position, and as the result dimension of the mold clamping apparatus in the direction of mold opening and closing can be shortened. Also, particularly the moving die plate can be avoided to tilt.
