METAL MOLD AND PRESS DEVICE

摘要

Engaging surfaces A1-A4 for engaging with each other during a pressing operation and a pressing surface 12 are provided in a mold that is composed of an upper mold part 10 and a lower mold part. A guide channel 20 is formed in the engaging surface A1 provided by an inner surface 16a of a side wall 16. When the upper mold part 10 and the lower mold part engage with each other, the guide channel 20 is covered by the engaging surface of the lower mold part to form a tunnel like passage. Lubricant that is introduced from a first aperture 21a is recovered from a second aperture 21b through the guide channel 20. Part of the lubricant that flows through the guide channel 20 is supplied to the engaging surfaces A1-A4.
