然而当塑件有内部形状时,在它冷却下来将会包紧型芯并且有必要采取一些脱模方法。
However, when the molding has internal form, the molding, as it cools, will shrink onto the core and some positive type of ejection is necessary.
此系统主要解决了四个难点:浇注系统设计、冷却系统分析、型腔、型芯的曲面造型设计、装配图和零件工作图的设计绘制。
With this system, the runner gate system design, mold cooling analysis, surface modeling, and automatic drawing could all be well carried out on microcomputer.
针对热轧带钢因卷取后钢卷内外圈与芯部的冷却速度不同,导致带钢成品头尾强度高、塑性低的问题,提出了卷取温度凹型控制模式。
U-shaped control model for coiling temperature was put forward to improve the high strength and low plasticity of head and tail of hot rolled strip.
