The invention belongs to the technical field of automobile parts, and particularly relates to an integrated two-cavity type fuel urea tank and a forming process thereof.The integrated two-cavity type fuel urea tank comprises a fuel urea tank body, the fuel urea tank body is divided into two closed cavities of a fuel tank body and a urea tank body through a sealing partition plate arranged inside the fuel urea tank body, and the edge of the sealing partition plate is provided with a T-shaped structure; the T-shaped structures of the top face and the bottom face of the sealing partition plate are each provided with at least one fixing hole. The sealing partition plate is installed in the rotational molding mold through the connecting piece in the fixing hole, the installation structure can be repeatedly used and is easy to disassemble and assemble, and feeding and rotational molding are conducted at the two ends of the rotational molding mold at the same time. The two closed cavities of the fuel tank body and the urea tank body are formed through integral rotational molding, the problem that in the prior art, the wall thickness of the joint of the two tank bodies is overlapped is solved, the overall structure is lighter, the forming technological process is simple, and operation is convenient.
Description
technical field [0001] The invention belongs to the technical field of auto parts, in particular to an integrated two-cavity fuel urea tank and its forming process. Background technique [0002] With the rapid development of the automobile industry and the improvement of automobile environmental protection requirements, automobile fuel tanks and automobile urea tanks are important safety and regulatory parts in automobile parts, and their structure optimization and performance improvement have become the major automobile manufacturers. solved problem. [0003] The fuel tank and the urea tank are two independent boxes, usually the fuel tank is blow molded, and the urea tank is blow molded or rotationally molded. How to combine the two independent unit designs of the fuel tank and the urea tank is very critical. In the prior art, the method adopted is to simply combine the fuel tank and the urea tank together, which will cause the problem of overlapping wall thickness at the...
