摘 要
在塑料工業(yè)中，注塑模是一種應(yīng)用廣泛，實(shí)用性強(qiáng)的塑料成形技術(shù)。本文作者主要研究了旅行餐碗的注塑模的設(shè)計(jì)。本文結(jié)合大量資料研究了塑料的成形工藝，模具的制造。對(duì)制品進(jìn)行了工藝分析、收縮率的計(jì)算等。根據(jù)制品的重量等因素確定了注塑機(jī)的型號(hào)。在模具結(jié)構(gòu)設(shè)計(jì)時(shí)，結(jié)合現(xiàn)有的資料，對(duì)模具結(jié)構(gòu)進(jìn)行了綜合考慮。對(duì)模具的各模板及各零部件進(jìn)行了設(shè)計(jì)與計(jì)算。在本文中使用了三板式單型腔模具，對(duì)模具的各部分零件進(jìn)行了設(shè)計(jì)與計(jì)算，以及對(duì)水道的設(shè)計(jì)與安放位置等。對(duì)于脫澆口本文提出了一種方案，既應(yīng)用鋼球與彈簧，并對(duì)模具的保養(yǎng)與維護(hù)提出了幾點(diǎn)要求。本文在結(jié)合了大量的資料進(jìn)行分析與研究的基礎(chǔ)上，對(duì)本設(shè)計(jì)提出了多種設(shè)計(jì)方案，并對(duì)它們進(jìn)行了分析與比較，確定了最佳的方案。在設(shè)計(jì)時(shí)，結(jié)合大量的數(shù)據(jù)，并通過(guò)計(jì)算，確定各重要的尺寸。使設(shè)計(jì)方案得到進(jìn)一步的完善。

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
