The present disclosure provides a self-tapping plastic bump for injection molding a part. A molded part includes a plurality of surfaces and a projection extending from one of the plurality of surfaces. The projection includes a body and an aperture extending through a central portion of the body. The projection also includes a first pocket extending through a sidewall of the body and into the aperture and a second pocket extending through an opposing sidewall of the body and into the aperture. The first pocket and the second pocket each define an inwardly tapered wall. The first pocket and the second pocket are axially spaced apart along the body and diametrically opposed.
本公开提供了“用于注塑成型零件的自攻塑料凸起”。一种模制零件包括多个表面以及从所述多个表面中的一个表面延伸的凸起。所述凸起包括主体以及延伸穿过所述主体的中心部分的孔。所述凸起还包括延伸穿过所述主体的侧壁并进入所述孔中的第一凹穴以及延伸穿过所述主体的相对侧壁并进入所述孔中的第二凹穴。所述第一凹穴和所述第二凹穴各自限定向内锥形壁。所述第一凹穴和所述第二凹穴沿着所述主体轴向地间隔开并且在直径上相对。
