摘　　要：以某空调器壳体为例,分析了该塑料制品的成型工艺,从浇注系统、成型零件、脱模机构、冷却系统设计等方面,详细阐述了该三板式注塑模具结构设计要点,通过采用典型的多滑块与大角度斜顶相结合的抽芯结构、多油缸顶出复位系统,该注塑模具的使用寿命和稳定性得到了较大的提升,同时采用CAE软件进行了模具结构开发设计,最终获得了一套切合实际的浇注系统方案,在该基础上对模具结构进行优化,使注塑模存在的潜在风险显著降低,模具品质大幅提升,试模次数显著减少。实验结果表明,该模具设计合理,工作稳定,注塑生产的塑料制品的质量较好,具有较强的实用价值,可以为类似大角度斜抽芯注塑模具的结构设计提供理论指导。Taking an air conditioner shell as an example,the molding process of the plastic product was analyzed.From the aspects of gating system,molding parts,demoulding mechanism and cooling system design,the key points of the structure design of the three plate injection mold were elaborated in detail.By using the typical core pulling structure combined with multi slide block and large angle inclined top and multi cylinder ejection reset system,the service life of the injection mold was improved Stability had been greatly improved,at the same time,development and design of die structure by using CAE simulation analysis software and finally got a set of suit the actual gating system solutions,on the basis of optimizing the mold structure,reduced the potential risk of the existence of injection moulds,improved the quality of the mould and reduced test times.The practice showed that the mold design was reasonable,the work was stable,the quality of plastic products produced by injection molding was good,and it had strong practical value,which could provide great guidance for the structural design of similar inclined core pulling injection mold.
