摘 要
介紹了當(dāng)今塑料模具工業(yè)發(fā)展的狀況,分析了充電器蓋板的結(jié)構(gòu)工藝性,研究了模具的整體結(jié)構(gòu),首先應(yīng)用Moldflow軟件對塑件進(jìn)行澆口位置和填充分析,然后應(yīng)用UG軟件設(shè)計模具的三維模型,最后應(yīng)用Moldflow軟件對塑件進(jìn)行流動、冷卻和翹曲分析。發(fā)現(xiàn)通過設(shè)計合理的側(cè)向抽芯機(jī)構(gòu)、澆注系統(tǒng)、推出機(jī)構(gòu),冷卻系統(tǒng)和排氣槽,可以有效的減少塑件上氣穴、熔接痕、翹曲及凹陷等成型缺陷。結(jié)果表明,本文設(shè)計的模具結(jié)構(gòu)較合理,可有效減少塑件的成型缺陷,得到高品質(zhì)的塑件產(chǎn)品。

The Injection Mold Design of a Plastic Charger Cover
Abstract
This article reports the current development situation of the plastic molds industry. Analyze the structural processability of charger's cover. Study the overall structure of the mold. First, apply Moldflow to analyze the gate location and filling of the parts. Second, apply UG NX to design the 3D model of the injection mold. Final, apply Moldflow to analyze the flow, cool and warp of parts. Discover that through rational design of side core pulling, runner system, ejection mechanisms, cooling System and vents, the mold can effectively reduce the molding defects of air traps, weld lines, wrap and sinking on the parts. The result shows that, the rational mould structure of this article designs can effectively reduce the molding defects, and obtain high-quality plastic products.
