Injection Mould Design of Mobile Phone Back Shell

Abstract:

This article introduces the injection mould design of mobile phone back shell. The mould adopts 3-plate mold structure, pin-point gate for feeding in the glue, ejector pin and pieces for stripping. The under-cut at the side edge adopts 3-side sliding block molding, and the cooling system adopts “U”-shape coolant gallery. It is proved by production practice that the mould structure is reasonable, stripping smoothly and the plastic parts quality meets the design requirements.
