AI Technical Summary
Technical Problem
对于具有深骨位结构的轴流风轮，开模时产品骨位与模具镶件间产生的真空吸附力和包紧力易导致产品变形，后续顶出过程中因受力不均进一步放大叶尖跳动偏差
Benefits of technology
[0016]由上可知，本申请提供的一种轴流风扇叶尖跳动控制模具及其开模顶出机构，通过第一顶杆与第二顶杆同步顶出轴套与叶片尖端，结合分阶段开模抽芯及复位机构，有效平衡脱模应力，避免产品局部变形，从而显著提升叶尖跳动精度，具有结构稳定、成本可控的优点。

Abstract
The utility model relates to injection molding mold technical field especially, relate to a kind of axial flow fan blade tip runout control mould.The axial flow fan blade tip runout control mould provided in the present application, including panel, A plate, B plate, bearing plate, thimble plate and center shaft insert, A plate and B plate mold form axial flow fan mold cavity, center shaft insert is fixed in bearing plate and extends into mold cavity and forms shaft hole.Thimble plate is equipped with multiple first ejector rods and multiple second ejector rods, first ejector rod top end is used to simultaneously eject axial flow fan wheel sleeve lower end surface, second ejector rod top end is used to simultaneously eject blade tip, and first ejector rod and second ejector rod are fixed in the synchronous action of same thimble plate.The scheme is simultaneously ejected sleeve and blade tip to realize uniform stress, can effectively inhibit product deformation, improve blade tip runout precision.
