Injection mold is an important tooling for industry products,it is the core of the modern manufacturing industry and in most countries injection mold design and manufacturing technology have become the keywords of measuring it is production technology.
This design through analysed the process and material of chemical instrument cover,choosed the proper injection machine,and roughcast reasonable injection mold design scheme.In the design process,it used the configuration of two cavityin one plate.And through designing the parting line,running gate system,modeling parts,ejection stripping mechanism,cooling system,choosing adaptive standard mould base and standard parts,it finised the whole mold design scheme for the chemical instrument cover.
