A machine for rotational molding of products comprises means (12, 14, 16, 17) for driven rotation of a mold around perpendicular axes (13, 15), means (22) for direct heating of the mold and means (21) for commanded opening of the mold in half molds. The machine further comprises combined means (23, 24, 25) for arresting in a predetermined position of the rotating means of the mold disengageable retaining means (26, 27) for retaining the product in a preset half mold, and evacuating means (28, 50) for evacuating the product that are suitable for being introduced between the open half molds when the rotating means is stopped in said predetermined position and which is suitable for receiving the product discharged from said preset half mold upon the release of the retaining means.
