Abstract
A die casting machine has a carousel and a plurality of molds disposed around the carousel. The carousel rotates about a central axis, such that each of the plurality of molds comes into a position for casting in turn. Each mold has a toggle mechanism and extraction pins. A gripping mechanism may extend up through a hole in the carousel table to couple the toggle mechanism to an actuator. At least one of the pins may have a pin brake such that the pins remain in position when the mold is opened, suspending a newly cast metal part in mid-air, when the brake is activated. When the brake is deactivated, the pins may retract, and the part may be removed without damaging the cast part.
Claims20
A die casting apparatus for casting a part including an inserted component, the die casting apparatus comprises:
- a plurality of molds, each comprising a first portion and a second portion and forming a cavity wherein the inserted component is inserted, such that the inserted component is embedded and integrated within the part, and a first toggle mechanism coupled to the first portion and arranged such that the first toggle mechanism opens and closes the first portion of the mold;
- a rotary carousel, wherein the plurality of molds are disposed on the carousel, and the carousel comprises a drive for rotating the carousel and a rotary table, wherein the rotary table comprises at least one through hole, the at least one through hole being disposed under the first toggle mechanism of one of the plurality of molds, when the one of the plurality of molds is positioned in a casting position;
- and
- a first mold opening actuator comprises a grip arranged at one end of a linear actuator, such that the grip is capable of extending through the at least one through hole of the rotary table, when the first mold opening actuator is arranged under the first toggle mechanism of the one of the plurality of molds, when the one of the plurality of molds is positioned in a casting position on the rotary carousel;
- and
- wherein the grip of the first mold opening actuator temporarily couples the opening actuator with the first toggle mechanism of the one of the plurality of molds, when the one of the plurality of molds is positioned in a casting position by extending through the at least one through hole and gripping the first toggle mechanism of one of the plurality of molds, when the one of the plurality of molds is positioned in a casting position, and the first toggle mechanism activates the closing and opening of the first mold portion of the mold, when the first mold opening actuator is activated for closing and opening of the first portion of the mold.
