Abstract
A mold for producing a part, such as a turbomachine blade model, by injecting wax into a cavity, the cavity including at least two cavity elements, each of which is supported in a cavity block. The two cavity blocks are mobile relative to one another between a closed position for injecting the wax and an open position for removing the part following the injection of the wax. The two cavity blocks are mobile in a horizontal plane.
Claims8
A mold for producing a turbomachine blade model comprising:
- a cavity including at least a first cavity element and a second cavity element;
- a first cavity block supporting the first cavity element;
- a second cavity block supporting the second cavity element;
- a base plate that is fixed and forms a base for the first cavity block and the second cavity block;
- a plate that is mobile in translation relative to the base plate along a first direction;
- and
- a mechanism extending from the plate through the base plate to the first cavity block and the second cavity block in a second direction perpendicular to the first direction,
- wherein wax is injected into the cavity and the first cavity element forms an intrados face and the second cavity element forms an extrados face of a blade of the turbomachine blade model,
- wherein the first cavity block and second cavity block are mobile relatively in a horizontal movement plane between a closed position for injecting the wax and an open position for removing a part following injection of the wax, and
- wherein the mechanism drives the first cavity block and the second cavity block in the horizontal movement plane with a relative displacement between the plate and the base plate along the first direction.
