玩具小車上蓋注塑模具設計與工藝分析【一模兩腔】

摘  要

本文是針對玩具小車上蓋的注塑模具設計與工藝分析。首先對玩具小車上蓋進行三維設計，并且對其進行結構分析。然后根據玩具車上蓋的結構分析其工藝特點，主要包括材料工藝特性、制件的工藝結構特點，然后根據工藝選擇注射機，并對注射機的參數進行校核。接著進行注塑模工藝設計，主要包括分型面設計、型腔數量和布局設計、澆注系統(tǒng)設計、模架選擇、推出機構設計和冷卻系統(tǒng)設計，其中分型面設計和澆注系統(tǒng)設計是重點設計內容，其設計結果需要進行模流分析驗證。最后對所設計的零件進行裝配并給出最終設計結果。

本文設計過程中主要使用UG NX 8.5/ MOLDWIZARD經行設計，用到的設計內容包括三維造型、模具設計、分型面設計、澆注系統(tǒng)設計和冷卻系統(tǒng)設計，最終結果由UG裝配完成。

Abstract

This article is the injection mold design and process analysis for the cover of toy car, first designs three-dimensional toy car shell, and then analyzes its technological features which includes material properties, structural features of parts of the process and select the injection machine. Then article design injection molding process which includes sub-surface design, the number and layout of the cavity designing, gating system design, mold selection, launches mechanism design and cooling system design, checking the process parameters of mold design.

In this article, the design is mainly used UG NX 8.5 / MOLDWIZARD. The content of the design includes three-dimensional modeling, mold design, parting surface design, gating system design and cooling system design, the final result is done by UG assembly.
