Spraying device used for rotational molding

The invention provides a spraying device used for rotational molding, belongs to the technical field of rotational molding and solves the problems that the conventional rotational mold is poor in quality after being formed and the manufacturing is more troublesome. The spraying device used for rotational molding comprises a machine frame; a spraying workbench is mounted at the middle of the machine frame; a female mold is fixedly mounted on the upper end surface of the spraying workbench; the spraying device further comprises a control cabinet, a guide block, a slide block and a spray gun; a slide rail device I and a slide rail device II are arranged on two sides of the upper end of the machine frame respectively; the guide block and the slide block are arranged on the slide rail device I and the slide rail device II respectively; a slide bar is fixedly connected between the guide block and the slide block; a spray gun seat is sleeved on the slide bar and can slide to and fro along the slide bar; the spray gun is mounted on the spray gun seat and is positioned above the female mold; and the control cabinet is electrically connected with the spray gun. The spraying device used for rotational molding has the advantage that the formed mold is good in quality, simple in manufacturing and low in cost.
