    摘要： A mold clamping apparatus for a die casting machine is provided. The apparatus can include a base, a fixed die plate standing fixedly on an end of an injection side of the base and defining a cavity therein, and a moving die plate arranged so as to proceed and retract on the base facing the fixed die plate and defining a cavity therein. A first versatile main mold can be disposed in the cavity of the fixed die plate and adapted to receive an insert die. Further, a second versatile main mold can be disposed in the cavity of the moving die plate and adapted to receive an insert die.

    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： There is provided a mold clamping apparatus which has a space-saving apparatus construction and can easily carry out mold replacement. The mold clamping apparatus includes: a base; a fixed die plate, fixed on the base, for mounting a fixed mold thereto; a movable die plate, disposed opposite the fixed die plate and movably on the base, for mounting a movable mold thereto; a mold opening/closing means for moving the movable die plate closer to and away from the fixed die plate; a plurality of mold clamping cylinders provided in the fixed die plate; mold clamping pistons fit in the mold clamping cylinders; a plurality of tie bars, each detachably mountable at one end to each mold clamping piston and penetrating the movable die plate and extending; a coupling means for releasably coupling each tie bar to the movable die plate at a position as determined depending on the sum of the thickness of the fixed mold and the thickness of the movable mold; and a tie bar retreating means which, when the movable die plate is in a backward position to form a space for mold replacement operation, moves at least one of the plurality of tie bars, which obstructs the mold replacement operation, backward to a retreat position.

    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.
