摘要
详细分析了仪表壳中6处的内侧凹(孔)的结构,设计了斜顶杆内侧抽芯机构;分析了抽芯距离、抽芯角度和顶出距离之间的关系。通过控制抽芯角度,避免了斜顶杆与塑件的干涉。对模具的其他结构进行了优化,便于模具的使用与维护。实践证明,该模具结构稳定,塑件质量高。
6 concaves （holes） in the inside structure of the instrument shell are analyzed in detail, and the inside core-pulling mechanism with the angle ejector rod is designed. The relationship of the core pulling distance, core pulling angle and the ejection distance is analyzed. By controlling the core pulling angle, the interference between the ejector rod and plastic part is avoided. The other structure of the mould is optimized, and the operation and maintenance of this mould are also improved. The practice has proved that the mould structure is stable, and the plastic part is of high quality.
