Abstract: In order to prevent the molded part from sticking to the slider block, an ejection mechanism was set in the slider block. Taking the molded part of feeding bottle handle as an example, an injection mould was designed according to the analysis of the structure characteristics and processing technology of this part. The mould structure and its working process were introduced. The ejection mechanism set in half slider blocks, the forced demoulding mechanism and the cooling system were illustrated in detail. It was proved that the ejection mechanism set in slider was adequate for demoulding and was helpful to the quality of molded parts.

Key words: feeding bottle handle, injection mould, half slider block, ejection mechanism, forced demoulding
