Abstract
This passage focus on the design of the rear bumper mould hot runner system.As a new technology of the mould industry, compare with the cold runner system which has many advantages such as higher efficiency,higher quality of the plastic part and save material.As a important compent of the plastic mould,the design & manufacturing of the hot runner system affect the quality of the part and the peried of the mould.In order to reduce the risk&cost of the mould,the advenced country such as Germany,America and Janpan,they would use proffesinal software to analyze the process of the injection before design and manufacturing,so that they can preview the probably flaw of the injection process.With this we can modify the dimention of the runner to get a better injection condition.
In this passage,I take the rear bumper of the car as a example.According to the customer file,I measure the dimention of the rear bumper mould to give a analyze of the injection process.According to the structure of the mould and the relation of the parts,I finally give the procedure of the analyze and design With the software Solidworks I designed 3D model of the hot runner system.Also I give rear bumpers of the car some analysis, comparison, optimization and improvement according to the size and structure of the hot runner system , so that the design of injection mould to achieve its best work status and the expected life cycle.
