Mold device for a rotational molding device

A mold device configured for use in a rotational molding device configured to perform a rotational molding process is performed by rotating the mold device with a robot arm, the mold device comprising:

• a connector part for connecting the mold device to the robot arm of the rotational molding device;
• at least a first mold part and a second mold part comprising thermally conductive material and configured to assemble to each other and enclose a mold cavity in an assembled state, each of the first and second mold parts comprising an interior face facing towards the mold cavity and an exterior face facing away from the mold cavity;
• attachment means for releasably attaching the first and second mold parts to each other;
• heating elements arranged in first grooves positioned in the exterior face of at least one of the first and second mold parts, the heating elements configured to heat the respective mold part;
• and
• cooling elements arranged in second grooves positioned in the exterior face of the at least one of the first and second mold parts in between the first grooves, the cooling elements configured to cool the respective mold part.
