A method for molding a two-piece blow molded hollow tank by using auxiliary male molds includes the following steps: 1) blanking two parisons; 2) closing mold halves of a mold and a pre-molding template; 3) pre-stretching the molten parisons by using auxiliary male molds in the pre-molding template; 4) performing internal high-pressure blow molding, and pre-molding two housing portions; 5) opening the mold, and withdrawing the pre-molding template; 6) moving in a component built-in mechanism to perform built-in component connection; 7) moving out the component built-in mechanism; 8) closing the mold for the second time and finally blow molding a hollow tank; and 9) opening the mold and taking out the product.

Method for molding two-piece blow molded hollow tank by using auxiliary male molds

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.
