Abstract: A two-cavity, two-component injection mould with turn plate adiabatic extension nozzle was designed for production of two-color handled cup. The key issues of the design, structure and working process of the mould were introduced. The inner of the cup was molded in a whole cavity and the outer was molded in half-type cavity. The half split blocks were moved by hydraulic mechanism. The half split sliding blocks were used to shorten the height of cavity of semi product and the blocks were moved by slanted guide pillar core pulling mechanism. It was proved that the movement of the mold was reliable with low cost and the quality of the products was good.

Key words: design, injection mould, cup with a handle, two-color
