摘要
结合某带内圆环槽密封盖产品注塑成型脱模的需要,设计了一副可对内圆环槽脱模的六滑块差速侧抽芯机构及模具,构建了该机构运动的数学模型。从运动几何关系、驱动力学等方面对机构运动的原理、可行性等进行了数学几何关系分析和论证,介绍了能可靠执行该机构功能的相应的模具结构。该机构基于数学建模分析进行设计,构思巧妙,对同类塑料制品脱模机构的设计有较大参考价值。
According to the needs of injection molding and ejection of the sealing ring cover product in an inner belt, a six speed differential side core pulling mechanism and a die for stripping the inner ring groove was designed. A mathematical model of the mechanism motion was constructed. The mathematical geometry relation of the mechanism movement was analyzed and demonstrated from the aspects of motion, geometry and drive mechanics. The corresponding die structure that can reliably perform the function of the mechanism was introduced. The design of the mechanism is based on mathematical modeling and analysis, and it is ingeniously conceived. It is of great reference value to the design of the demoulding mechanism of the similar plastic products.
