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
An apparatus for forming an article, said apparatus comprising:
- (a) at least one die having a die cavity to receive material to be used for forming the article, said material being at least partially molten;
- (b) at least one punch adapted to slidably engage the die cavity and to exert a forming pressure on the material when in the die cavity;
- and
- (c) at least one pin for forming an article feature, the pin being adapted to slidably engage the die and to contact the material, the at least one pin being further adapted to move upon exertion of the forming pressure between a first position and a second position, prior to solidification of the at least partially molten material, 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;
- and
- 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.
