Method of manufacturing die
First Claim
1. A method of manufacturing a die having batch supply holes arranged at a batch supply side thereof, slits arranged at a batch discharge side thereof for forming the batch, and batch hold portions made of lateral holes, which are arranged at least at intersecting portions between the batch supply holes and the slits and are arranged corresponding to the slits, said method comprising the steps of:
- (a) preparing a die main body;
(b) performing batch supply hole machining with respect to one principal plane of the die main body to form the batch supply holes;
(c) using a cutting apparatus to perform slit machining with respect to the other principal plane of the die main body to form the slits;
(d) without removing the cutting apparatus from the die main body, continuously performing lateral hole machining to form the batch hold portions, which are arranged at least at intersecting portions in the die main body between the batch supply holes and the slits and are arranged corresponding to the slits; and
(e) thereafter removing the cutting apparatus from the die main body to thereby form an integral die.

Abstract
The method includes the steps of preparing a die main body; performing batch supply hole machining with respect to one principal plane of the die main body to form batch supply holes; using a cutting apparatus to perform slit machining with respect to the other principal plane of the die main body to form slits; without removing the cutting apparatus from the die main body, continuously performing lateral hole machining to form the batch bold portions, which are arranged at least at intersecting portions in the die main body between the batch supply holes and the slits and are arranged corresponding to the slits; and there after removing the cutting apparatus from the die main body to thereby form an integral die. Alternatively, the above slit machining and continuously performing lacteral hole machining steps can be performed first and followed by performing the batch supply hole machining step.
