隔震橡胶支座模具与加工工艺设计.doc

1、隔震橡胶支座模具设计和加工工艺摘 要：目前应对地震灾害，提高建筑抗震性能的结构设计理念，可以归纳为“抗震”和“隔震”两种思路。以前为了个抗震就是使建筑物加强他的构建强度。因此，允许结构和构件在地震中出现一定程度的损坏，程度往往难以控制。但是使用隔震技术后，就能够减少建筑物在地震中的摇动，使得建筑不至于损坏严重。结构比较复杂，模具重量比较大，尤上、中、下三模组成来制出支座，压模分为开放式，封闭式，半封闭式。由于模具质量要求比较高，所以上下模采用 45#钢，中模采用锻钢。因为其性能在中上等，制造这种模具很适合。应该切入点余胶槽，手柄，型腔尺寸，收缩率,各种零件规格等等！我的设计内容是：橡胶支座系列

3、ngs construction. Therefore, it allows acertain degree of damage in structure and components affected by earthquake and it is oftendifficult to control. However, seismic isolation technology can reduce the shaking ofbuildings during the earthquake and make sure that buildings arent badly damaged. Th

4、econstruction is complex and the weight of mode is relatively large. The ultimate mold isconsists of upper, middle and lower mould and molding-die is divided into open, closed,half closed style. Because of the high quality requirements, the upper and lower moldsmade of 45# steel and middle mold made

These designs takes glue tank, handle cavitydimensions, shrinkage, parts specifications as a starting point, designs a mold based onbearing series- type of lead.Key words: Disasters；Seismic isolation rubber
