Abstract
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.
Claims4
A mold clamping apparatus for a die casting machine, comprising:
- a base;
- a fixed die plate standing fixedly on an end of an injection side of the base, the fixed die plate having a mold mounting surface defining a cavity therein and having a clamp cylinder formed at a portion in the fixed die plate;
- a moving die plate arranged so as to proceed and retract on the base facing the fixed die plate, the moving die plate having a mold mounting surface defining a cavity therein and having a fastening member fixedly fastened at a side face of the moving die plate;
- guide means arranged on the base in order to guide proceeding and retracting movement of the moving die plate;
- first drive means for allowing the moving die plate to proceed and retract on the guide means, the first drive means including the fastening member;
- tie bars passing through portions neighboring corners of each die plate and holding a clamping of the die plates;
- second drive means for producing a clamping force between the fixed die plate and the moving die plate through the tie bars, the second drive means including the clamp cylinder;
- a first versatile main mold disposed in the cavity of the fixed die plate and constructed and arranged to receive any of a plurality of insert dies having a range of different sizes, each insert die defining a cavity corresponding to the shape of an article to be molded;
- and
- a second versatile main mold disposed in the cavity of the moving die plate and constructed and arranged to receive any of a plurality of insert dies having a range of different sizes, each insert die defining a cavity corresponding to the shape of an article to be molded;
- wherein the distance between the mold mounting surface of the fixed die plate and the mold mounting surface of the moving die plate is substantially zero at a mold closing position.
