Abstract

A machine for manufacturing a hollow elastic ball includes a base, an X-direction driving device, a Y-direction driving device and a molding device. The X-direction driving device is installed on the base; an outer frame is driven by an X-direction motor to rotate about an X-direction rotation shaft. The Y-direction driving device is installed on the outer frame; a Y-direction motor fastened on the outer frame drives an inner frame to rotate about a Y-direction rotation shaft. The molding device includes a carrying plate fastened in the inner frame and a mold fastened with the carrying plate. When the mold is filled with liquid material, the outer frame and the inner frame simultaneously rotate about the X-direction rotation shaft and the Y-direction rotation shaft, such that the material is uniformly distributed over the inner wall of the mold so as to form a hollow elastic ball.
