摘 要
本設(shè)計(jì)說明書在在對(duì)塑料模具及塑料成型模具技術(shù)進(jìn)行系統(tǒng)研究的基礎(chǔ)上，對(duì)塑料水槽及其模具的設(shè)計(jì)做了全面的敘述。本設(shè)計(jì)design采用UG軟件作為開發(fā)平臺(tái)，不用草圖sketch，可以在建模狀態(tài)state下隨心at your will得到所需要的結(jié)構(gòu)形狀form，提高improve了建模的精確性accuracy，加快了建模的速度。塑料水槽的設(shè)計(jì)的內(nèi)容包括制品的材料選擇，壁厚的確定，收縮率的確定以及用UG軟件繪制的過程。塑料水槽的模具的設(shè)計(jì)，包括型腔數(shù)目的確定，型腔分形面及澆注系統(tǒng)的選擇，注射成型模具零部件的設(shè)計(jì)及其它輔助結(jié)構(gòu)件。在型腔數(shù)目的選擇中，采用了一模四腔的設(shè)計(jì)方案，成型費(fèi)用達(dá)到了最佳。

ABSTRACT
On the basis of the systemic study of plastic mould and technology of the mould for plastics, this paper makes a depiction of the designs of the plastic flume and its mould. In my design, UG is used as a modeling tool. Without sketch, UG can set up the model at your will to improve the modeling accuracy and speed the modeling. The flume’s design includes the selection of the material, thickness, contractibility and how to use UG to plot it. The mould’s design includes the selection of the cavity’ number, the cavity’ fractal face and moulding system; in addition, this design includes the designs of injecting mould’ accessory and other parts. Especially, in the selection of the cavity’ number, I adopt the plan of four cavities in a mould in order to make the charge least.
Key words: mould ¨ UG system; plastic flume; mould for plastics; mould’ design
