<p>A system for continuously monitoring the temperature of a rotational mold (M) mounted to a rotational molding apparatus (10), the apparatus including a base (50), a drive device (11) supported on the base for 360 degree rotation thereon, a mold (M) and a rotatable shaft (13s) extending from the drive device (11) for supporting the mold, the mold being rotatable through a 360 degree axis of rotation with respect to the shaft, and the shaft being rotatable through a 360 degree axis of rotation with respect to the drive device. The system comprises a heat sensor (14) mounted in the mold; a series of first (16), second (26), and third (36) slip ring assemblies, each including a pair of slip rings and a contact device (21, 29, 39), the assemblies maintaining continuous electrical contact during rotation of the mold, the shaft and the drive device; and a control device (40) receiving electrical signals from the heat sensor through the first, second and third slip ring assemblies for continuously monitoring the temperature of the rotational mold. A method for controlling a rotational molding apparatus is also disclosed.</p> |
