I 塑料水壺外殼注塑模設計 摘要 本課題主要是針對塑料水壺外殼的模具設計。塑料水壺外殼具有質量輕、
易于清潔、強度高、使用壽命長、價格低廉、制品美觀等特點。通過對塑件進
行工藝分析和比較?根據(jù)制品的性能及特點?最終設計出一副注塑模。該課題
從產(chǎn)品結構工藝性、具體模具結構特點出發(fā)?對產(chǎn)品的三維造型?分型面?模
具的澆注系統(tǒng)、其成型部分的結構、冷卻系統(tǒng)、脫模機構?注塑機的選擇及有
關參數(shù)的校核都有詳細的設計?同時簡單的說明了該模具的加工工藝。通過整
個設計過程表明此模具能夠達到塑件所要求的加工工藝。

關鍵詞?注塑模具? 塑料水壺外殼?聚丙烯



Abstract mold design for the plastic kettle shell Abstract The main topic is covred in mold design for the plastic kettle shell with a light weight?easy
to clean, high strength , long service life, low prices, good apperance quality and so on . Through
the process of plastic parts for analysis and comparison, in the light of the performance and
feature of the product, we design an injection mold finally. Process from the product structure
of the project, specific mold structure starting on the casting mold system, there are detialed
design wit,h the thre-dimensional modeling, binary type surface, gating system, the mould
stucture, cooling system, demoulding mechanism, the choice of the injection molding machine,
and the check of some related parameter, and introduce the mold processes simply. Through the
entire design process that can be achieved in the mold plastic parts required in this process.
Based on the volume and determine the process performance of plastic injection molding
method using plastic parts production. The product is desighned for mass production, so the
design of the mold requires a high injection efficiency, and the gating system to be able to
automatic mold ejection., in addition to use site gate according to product structural feature, so
we choose a single sub serface injection mold, site gate automatic ejection structure. Mold cavity
one-cavity mold, gating system using site gate forming, introdued extrusion device to complete
sixth putting the introduction of plastic parts. In consideration of the factors such as the
performance and so on, use circulating cooling system to cool products.
Key words: injietion mould?Plastic kettle shell?Polypropylene
