塑料模具脱螺纹机构自动控制方案的设计

The Design of the Automatic Control on Plastic Mold Thread Demoulding Mechanism

很多塑料产品中存在内、外螺纹,解决塑件螺纹脱模问题是这类产品模具设计的关键。本文研制了一种用伺服电机驱动的新型模具脱螺纹同步机构,该机构采用机电一体化技术,能自动适应制件不同螺距和不同塑料材料性能的变化,很好地解决目前由于脱螺纹时不同步所造成的各种质量问题。对于模具行业来说这是一种重大改进,有良好的应用价值和市场前景。

Many products' plastic work piece has the internal screw thread and external screw thread,and the key of this kind of mold design is how to solve the problem of thread demoulding.This paper introduces a design of automatic control mechanism for the plastic mold thread demoulding.This mechanism uses the Electromechanical technology,can adapt to the work pieces with different pitch and different material performance automatically.This system solves various quality question caused by the asynchronous thread demoulding,it is a major improvement for mold industry and has great application value.
