Abstract
An apparatus for forming an article by forging. The apparatus has at least one die having a die cavity to receive material, said material being at least partially molten, and at least one punch to slidably engage the die cavity and to exert a forming pressure on material disposed in the cavity. There is also at least one pin for forming an article feature. The pin is to slidably engage the die and to contact the material, the pin being further to recede upon exertion of the forming pressure and to exert a feature forming pressure when receded and thereby form the article having the article feature when the material solidifies under the forming pressure.
Claims6
A method of forming an article having an article feature, the method comprising:
- (a) locating at least one pin at a first position relative to a die cavity;
- (b) inserting into the die cavity a molten material to be used to form the article;
- (c) moving at least one punch relative to the die cavity to contact the molten material to form the article;
- and
- (d) moving the at least one pin to a second position relative to the die cavity, the movement of the at least one pin being prior to solidification of the molten material,
- wherein the movement of the at least one pin is a consequence of the movement of the at least one punch;
- and
- wherein the at least one punch contacts the at least one pin prior to the at least one punch contacting the molten material.
