A rigid connecting device for connecting the upper and lower surfaces inside an oil tank includes a connecting rod. The upper and lower sides of the connecting rod are each provided with a connecting end surface. The connecting end surface is provided with material-passing hole. The outer surface of the rigid connecting device is covered with high-density polyethylene. The upper and lower surfaces of the oil tank are connected by a connecting rod, and such arrangement is locally applied to areas where the rigidity of the oil tank is poor, so there are more effective space. The part of the rigid connecting rod contacting with the oil fuel is made of high-density polyethylene, so the requirements of strength and anti-corrosion can be satisfied.

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.
