Abstract
Among plastics industry, the note moulding to be one extensive application, practibility strong plastics take shape technology. Author of this text main research travel meal design that note moulded of bowl. This text combines the craft of taking shape of studying plastics of a large amount of materials, the manufacture of the mould . Have carried on calculation of craft analysing, shrinking rate,etc. to the products. Factor confirmed the type of the moulding plastics machine according to weight of products,etc.. In the structure design of mould , combine the existing materials, has considered the structure of the mould synthetically. Every template and all spare part in mould designed and calculates. In use three modes in Chinese operatic music form s of mould in the article originally, all part of part in mould designed and calculates, And the design and laying position,etc. of the water course . For take off runner this text get a kind of scheme out of, already used steel ball and spring, And the maintenance and maintaining some requests of proposition to the mould . This text is on the basis of analysedding and study after combining a large amount of materials, To originally designed and put forward many kinds of plans of designing, and analyse and compare them, Have confirmed the best scheme. In the design, combine a large amount of data, and pass and calculate, Confirm the each important size. Make the plan of design get further perfection.
Keywords: Traveling meal bowl The note moulding three modes Single type Water course
