Description

塑料壳体侧孔斜导柱内滑抽芯机构
技术领域
[0001] 本实用新型涉及一种塑料壳体侧孔斜导柱内滑抽芯机构,适用于所有制有侧孔的壳体状塑料制品,属于塑料模具领域。
背景技术
[0002] 采用塑料模具生产塑料制品,例如壳状塑料制品,壳状塑料制品的壳体上侧孔,因此,在脱模时,需要先对侧孔进行抽芯,才能将塑料制品脱出。现有技术的侧孔抽芯一般采用油缸带动外滑块外滑抽芯机构或者斜顶内抽机构,外滑抽芯机构的缺点是壳体外壁有分型线,外型不美观;斜顶内抽机构的缺点是壳体高度高,斜顶不好设计,稳定性差。
发明内容
[0003] 本实用新型的目的是为了克服已有技术的缺点,提供一种采用斜导柱内滑抽芯方式,结构简单,动作稳定,加工容易,壳体外型美观的塑料壳体侧孔斜导柱内滑抽芯机构。
[0004] 本实用新型塑料壳体侧孔斜导柱内滑抽芯机构的技术方案是:包括模具上复板和下复板,上复板连接垫板,垫板连接定模板,下复上安装模脚,模脚之间设置上顶针板和下顶针板上顶针板上连接顶针,模脚上安装动模板,动模板与定模板之间有成型的塑料壳体, 塑料壳体上制有侧孔,其特征在于所述的动模板内制有内滑槽,内滑槽中设置内滑块,所述的定模板下连接内斜导柱,内斜导柱穿过内滑块,在内滑块的内侧制有抽芯块,抽芯块与侧孔相配合。
[0005] 本实用新型的塑料壳体侧孔斜导柱内滑抽芯机构,脱模时,首先由注塑机动力带动动模板与定模板开模,开模时,动模板向下运动,相当于是定模板向上运动,使连接在定模板下的内斜导柱带动内滑块在内滑槽中向内滑动,使内滑块内侧的抽芯块从侧孔中抽出,开模结束,上、下顶针板带动顶针将塑料壳体顶出模具外,脱模完成。本方案结构简单, 抽芯动作稳定、可靠,加工容易,成本省。并且塑料壳体外型美观,质量好,档次高。
附图说明
[0006] 图1是本实用新型塑料壳体侧孔斜导柱内滑抽芯机构结构示意图。 具体实施方式
[0007] 本实用新型涉及一种塑料壳体侧孔斜导柱内滑抽芯机构,如图1所示,包括模具上复板1和下复板9,上复板1连接垫板2,垫板2连接定模板3,下复板9上安装模脚6,模脚之间设置上顶针板7和下顶针板8上顶针板7上连接顶针5,模脚6上安装动模板4,动模板4与定模板3之间有成型的塑料壳体10,塑料壳体1上制有侧孔11,其特征在于所述的动模板4内制有内滑槽12,内滑槽12中设置内滑块13,所述的定模板3下连接内斜导柱 15,内斜导柱15穿过内滑块13,在内滑块的内侧制有抽芯块14,抽芯块14与侧孔11相配合。脱模时,首先由注塑机动力带动动模板4与定模板3开模,开模时,动模板4向下运动,相当于是定模板3向上运动,使连接在定模板3下的内斜导柱15带动内滑块13在内滑槽 12中向内滑动,使内滑块13内侧的抽芯块14从侧孔11中抽出,开模结束,上、下顶针板7、 8带动顶针5将塑料壳体10顶出模具外,脱模完成。本方案结构简单,抽芯动作稳定、可靠, 加工容易,成本省。并且塑料壳体外型美观,质量好,档次高。
