Description

一种镶嵌式模具定位组件及其定位方法 技术领域
本发明涉及一种镶嵌式模具定位组件及其定位方法，属于导向件技术领域。
背景技术
目前模具定位组件是模具冲压过程中的一个重要零件，它的作用就是导向，支撑以及定位作用。对安全生产来说有着极大作用，也是保证模具生产精度的重要一环。
目前普通型导向组件法兰和导柱采用分开式的结构，这样的设计减弱了导向组件的强度，影响模具的使用寿命。普通型导向组件加工采用金属材料，冲压过程中金属的撞击对模具及导向件损害极大。普通型导向件结构复杂，安装繁琐，这样会降低模具的安装效率，不利于模具装配，维修。普通型导向件均采用螺丝固定锁紧设计，在长时间冲压工作中，螺丝容易松脱，这样会影响模具的安全生产，在实际生产中技术人员需要频繁的检查螺丝是否松脱，降低了模具生产效率。
综上目前普通型导向组件使用中有很多问题及不便需要改善，同时不少问题点对正常的模具冲压会有不良影响。
发明内容
针对现有技术存在的不足，本发明目的是提供一种镶嵌式模具定位组件及其定位方法，结构简单强度高，使用寿命长，安装使用方便快捷，导向精度好。
为了实现上述目的，本发明是通过如下的技术方案来实现：
