一种用于金属制品塑料包边垫圈注塑成型的紧固方法
本专利技术涉及一种塑料垫圈,特别涉及一种用于金属制品塑料包边垫圈注塑成型的紧固方法。
技术介绍
在使用金属制品的过程中,若金属制品的外沿尖锐则可能会伤手,若金属制品的表面坚硬则可能会磨损与其直接接触的其他物体的表面。为此,人们往往需要为此类金属制品加装塑料包边垫圈。塑料包边垫圈加工时,可将金属制品嵌入专用模具,利用注塑机专用设备进行注塑成型。在使用过程中,现有的金属制品塑料包边垫圈容易出现上下松动、左右滑动、内外移动甚至破损等现象,会影响金属制品塑料包边垫圈的使用寿命。为此,本专利技术的目的就是提供一种用于金属制品塑料包边垫圈注塑成型的紧固方法。
技术实现思路
本专利技术提供了一种用于金属制品塑料包边垫圈注塑成型的紧固方法,其特征在于在金属制品外边沿的内侧开有一个或一个以上的注塑成型紧固孔;所述注塑成型紧固孔位于金属制品外边沿与塑料包边垫圈内边沿之间;所述注塑成型紧固孔包含注塑成型紧固孔头部与注塑成型紧固孔颈部;所述注塑成型紧固孔头部通过所述注塑成型紧固孔颈部与所述金属制品外边沿连通,并进一步与塑料包边垫圈外边沿连通;所述注塑成型紧固孔颈部的粗细尺寸不大于注塑成型紧固孔头部的粗细尺寸;所述塑料包边垫圈外边沿位于所述金属制品外边沿的外侧。优选地,所述注塑成型紧固孔头部为圆孔,所述圆孔的直径大于所述注塑成型紧固孔颈部最细处的粗细尺寸。优选地,所述塑料包边垫圈注塑成型的材料为聚丙烯塑料。本专利技术与现有技术相比,具有以下优点和效果:结构合理、加工简单、不易脱落、紧固耐用。附图说明图1为根据本专利技术在金属制品外边沿的内 ...
