The invention relates to a hollow casting type rubber bushing assembly which comprises a joint ball pin, the joint ball pin comprises a ball pin body, the two ends of the ball pin body are integrally connected with ball pin ends correspondingly, connecting holes penetrating through the ball pin ends are formed in the ball pin ends, a hollow cavity is formed in the ball pin body, the two ends of the hollow cavity communicate with the connecting holes correspondingly, and the outer side of the ball pin body is sleeved with a lining shell. An operator firstly pulls the two ends of the end portion of the ball pin, stretches the two ends of the end portion of the ball pin and extrudes the ball pin body at the same time, the ball pin body is directly installed in the lining shell, the use frequency of an adhesive is reduced in the production process, therefore, independent components are independently produced, then the components are assembled through stretching and extruding methods, and the production procedures are reduced. Through communication between the hollow cavity and the connecting hole, the hollow casting process of the rubber joint ball pin is achieved through sand core casting, the self weight of the whole joint ball pin is reduced, and the effect that the whole lining assembly is light in weight is remarkably achieved.

    本申请涉及一种中空铸件式橡胶衬套总成,其包括关节球销,关节球销包括球销本体,球销本体的两端分别一体化连接有球销端部,球销端部上开设有贯穿球销端部的连接孔,球销本体内开设有中空腔,中空腔的两端分别与连接孔相互连通,球销本体的外侧套设有衬套壳。操作员先拉住球销端部的两端并向两端拉伸,同时对球销本体进行挤压,将球销本体直接装进衬套壳内,在生产的过程中减少胶粘剂的使用次数,从而对单独的部件进行单独生产,之后再通过拉伸、挤压的方法进行组装,减少了生产的工序,通过中空腔与连接孔的连通,用砂芯浇铸实现橡胶关节球销的中空浇铸过程,减少了关节球销整体的自重,本申请具有显著实现衬套总成整体轻量化的效果。
