Abstract
A molding method of blow-molding a hollow tank body with a built-in component is provided. The method molds the hollow tank body by molding the sheet parisons in the half molds. After the moving cooperation of the half molds, an expanding mechanism of a pre-molding template device, the template half plates and the bases, the half molds are respectively leaned against the closed template half plates, and the sheet parisons are leaned against the half molds by blowing and/or sucking so as to be pre-molded. The tank body is molded after placing the component into it. A pre-molding template device is also provided. An expanding mechanism and the template half plates are mounted on the bases, and the bases are mounted on a rail bracket, the bases are driven by a power device to move on the rail bracket.
