Abstract (en)
[origin: WO03097318A2] The invention relates to a double-walled mould that can be heated for producing moulded plastic skins in a rotational moulding process. According to the invention, the wall (1) of the device, which is responsible for shaping the skins is mounted in a guideway (10) so that it can be displaced in relation to an additional wall (2) of the housing, in order to compensate for thermal expansion. In addition, flow channels for a cooling/heating medium are arranged in the cavity between the housing walls (1, 2), said channels inducing a forced flow of the medium inside the cavity. The channels are preferably formed by struts (7), which are not connected to the shaping wall (1). The arrangement of the channels prevents to a great extent the intermingling of hot and cold medium during a temperature change.
