Abstract
An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.
Claims5
A method for producing encapsulated structural parts, comprising the steps of:
- providing an injection mold having a molding tool which has an arrangement of mold segments, wherein the arrangement forms a cavity;
- positioning a first structural part in the cavity and encapsulating with a material;
- removing and/or inserting at least one mold segment in order to alter a size of the cavity;
- and
- positioning a second structural part in the cavity for encapsulation,
- wherein the step of removing and/or inserting at least one mold segment includes using an exchange unit to rotate the at least one mold segment into or out of the molding tool in a direction perpendicular to a longitudinal axis of the molding tool.
