The invention discloses a refrigerator foaming mould series design system and method thereof. Foaming mould components are reasonably classified and then parametric operation is performed on the components so that the three-dimensional model of a new product and the engineering drawing thereof can be rapidly obtained through cooperation of series operation on the final assembly, and the attributes in the product component engineering drawing can be rapidly added. The new product can be rapidly obtained by modifying the numerical value of the active dimension according to the drawn model, and the parts and the components of the new product and the corresponding engineering drawing can also be obtained. The practice proves that the production efficiency can be greatly enhanced and the design cost of the new product can be reduced.
