Abstract: 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.
