低壓射蠟快速模具研製與應用

Fabrication and Application of Low-Pressure Wax Injection Rapid Toolings

摘要


本研究提出一個快速與低製造成本之射蠟模具製造技術,並運用田口方法探討低壓射蠟之較適製程參數。研究發現,影響低壓射蠟之蠟溢出量的最大影響因子為射蠟時間,其次是射蠟壓力。較適低壓射蠟製程參數為射蠟溫度82℃、射蠟時間2秒、射蠟壓力0.6 kgf/cm2以及矽膠模具預熱溫度60℃。

This paper proposed a method for fabricating silicone rubber molds for low-pressure wax injection molding. The wax spilling is one of the most troublesome problems during wax injection molding process. From the point of view of green manufacturing, the optimal processing conditions in the wax injection molding process were investigated using Taguchi method. The experimental results revealed that the most influential factor affecting the weight of spilled wax during wax injection molding process is the injection time. The optimal processing conditions in the wax injection molding process are injection temperature of 82 ℃, injection time of 2 sec, injection pressure of 0.6 kgf/cm2 and mold temperature of 60℃.
