Press die

Abstract

A press die comprises an upper die and a lower die each including a molding surface and a die main body; at least one first guide post attached to at least one of the die main bodies of the upper die and the lower die from its molding surface side; and at least one product pressing member mounted to the die main body to which the first guide post is attached so as to be slidable along the first guide post, at least one first guide hole into which the first guide post is to be inserted being formed in the product pressing member from its molding surface side. The die main body and the product pressing member mounted to the die main body undergo an alignment for each other through the first guide post.

What is claimed is:  
     
         1 . A press die comprising: 
 an upper die and a lower die each including a molding surface and a die main body;    at least one first guide post attached to at least one of the die main bodies of the upper die and the lower die from its molding surface side; and    at least one product pressing member mounted to the die main body to which the first guide post is attached so as to be slidable along the first guide post, at least one first guide hole into which the first guide post is to be inserted being formed in the product pressing member from its molding surface side;    the die main body and the product pressing member mounted to the die main body undergoing an alignment for each other through the first guide post.    
     
     
         2 . A press die according to  claim 1  wherein one product pressing member is mounted to only one of the die main bodies of the upper die and the lower die.  
     
     
         3 . A press die according to  claim 1  wherein one product pressing member is mounted to each of the die main bodies of the upper die and the lower die.  
     
     
         4 . A press die according to  claim 1  further comprising a bearing member fitted into the first guide hole of the product pressing member on its molding surface side for slidably receiving the first guide post.  
     
     
         5 . A press die according to  claim 1  further comprising a cap member for closing the first guide hole of the product pressing member, the cap member forming the same surface as the molding surface.  
     
     
         6 . A press die according to  claim 1  further comprising at least one second guide post projected on one of the upper die and the lower die for being inserted into a second guide hole formed in the other of the upper die and the lower die to align the upper die and the lower die.  
     
     
         7 . A press die according to  claim 1  further comprising spring means for elastically supporting the product pressing member with respect to the die main body.  
     
     
         8 . A press die according to  claim 1  further comprising a stopper pin for regulating a stroke of slide of the product pressing member.
