摘　　要：提出了一种适用于注射模成型制品局部薄壁的成型装置,由液压缸机构、型芯定位机构、限位机构和型芯组成,该装置解决了带有局部薄壁特征的制品成型时填充不满或成型质量较差的问题,通过设置可移动的型芯,实现了塑料熔体填充完成后再调整局部壁厚,避免填充不满现象的发生,提高了制品的成型质量。A local thin-walled forming device that suitable for an injection mould was pro- posed. The device was composed of a cylinder mechanism, a core positioning mechanism, a limiting mechanism and a core. During forming a local thin-walled feature product, the problems such as filling insufficiently and worse forming quality were solved by using the device. Through installing a removable core, the problem of poor forming quality could be resolved after the completion of the plastic melt to adjust the local wall thickness. The phe- nomenon of filling insufficiently was avoided and the quality of products was improved.
