Abstract
Based on the structural feature of feeding frames of printers and rheological characteristics of thermoplastic resins used,a three-plate mould with single cavity and three core pulling mechanisms were designed.The design skills were carefully analyzed,which include mould forming parts,gating system,fixed distance parting mechanism,side-core pulling mechanism,temperature control system,demoulding system and guiding positioning system.The deformation problem of side-core pulling plastic parts under a large tight force was solved by using a horizontal push rod.The precision of the injection-molded product reached MT3,the molding cycle was shortened by 8 ％ to 35 s compared with other same type of plastic parts.关键词
