Molding apparatus for stator of rotary electric machine

A molding apparatus for a stator of an electric rotary machine comprising:

• a first mold member enclosing one coil end of the stator including a stator core and a coil wound thereon with a clearance therebetween and positioned against one end surface of the stator core disposed outwardly of said one coil end;
• a second mold member set on the inner periphery of the stator core and enclosing the other coil end of the stator with a clearance therebetween while being positioned against the other end surface of the stator core disposed outwardly of said the other coil end, said second mold member being prevented from coming into direct contact with the first mold member when the stator core is held between the two mold members;
• and
• at least one of runner formed along the surface of said second mold member and opening at the inner peripheral surface of the stator core for communicating a first space formed between the first mold member and said one coil end with a space formed between the second mold member and said the other coil end.

• a second mold member set on the inner periphery of the stator core and enclosing the other coil end of the stator with a clearance therebetween while being positioned against the other end surface of the stator core disposed outwardly of said the other coil end, said second mold member being constructed such that when the stator core is held between the first mold member and the second mold member in a closed mold position a portion of the second mold member fitted to the inner periphery of the stator core is prevented from striking the first mold member with a force higher than a mold clamping force applied to the closed mold;
• and
• at least one of runner formed along the surface of said second mold member and opening at the inner peripheral surface of the stator core for communicating a first space formed between said first mold member and said one coil end with a second space formed between said second mold member and said the other coil end.
