ABSTRACT:
A clam shell rotational moulding machine of a type including a housing having a base portion with a flat base and four upstanding sides and a cover portion with a top and four depending sides can be moved from a fully closed position in which the top and base co-operate to form an enclosed housing to an open position in which the cover portion is lifted and a front one of the side walls of the base is opened to a horizontal position above a pivot axis across the bottom of the front wall. A spindle arm assembly normally mounted during the moulding process within the housing and extending into the housing through the side walls can be moved from the normal position to an unloading position. The spindle arm assembly is mounted upon a cantilever arrangement carried by a rigid frame mounted on the front door. Opening of the front door thus moves the spindle arm assembly and attached moulds to the unload position substantially vertically above the horizontal surface of the front door.
