Abstract
本实用新型公开了一种提高HDPE结构壁管表面光泽度的模具，属于高分子材料加工领域。其为采用内压法的管坯挤压成型模具，其挤出模具部分包括芯棒、芯棒外套有外口模，在芯棒与外口模端部共同安装有一个外模板法兰，外模板法兰与外口模、芯棒之间镶嵌安装有一个与芯棒同心的聚四氟乙烯套，聚四氟乙烯套在芯棒外置处与外模板法兰之间安装有与芯棒同轴的内模压板。本实用新型优点在于：其通过在挤出模具前镶嵌一块同心的聚四氟乙烯套来提高HDPE结构壁管表面光泽度，统一产品外观色度，结构简单、使用方便、成本投入低。
Description
技术领域
[0001] 本实用新型涉及高分子材料加工领域，具体为一种提高HDPE结构壁管表面光泽度的模具。
背景技术
[0002] HDPE双壁波纹管，是一种具有环状结构外壁和平滑内壁的新型管材，现有的HDPE双壁波纹管具有抗外压能力强、工程造价低、摩擦系数小、流量大、耐低温抗冲击性能良好等优点，由于其优异的性能和相对经济的造价，其越来越普遍的被推广和应用。
[0003] 在塑料加工业中，产品的光泽度主要是通过模具和高分子材料共同作用，高分子塑料在挤出过程中料丕表面会产生气孔，会影响产品的光泽度和外观色度，因而影响产品外观。
[0004] 本实用新型属于高分子材料加工领域，更具体来讲是在高分子塑料在挤出过程中消除料丕表面气孔从而提高产品的光泽度。
实用新型内容
[0005] 本实用新型用于解决的技术问题为提供一种提高HDPE结构壁管表面光泽度的模具，其通过在挤出模具前镶嵌一块同心的聚四氟乙烯套来提高HDPE结构壁管表面光泽度，统一产品外观色度。
[0006] 本实用新型解决技术问题采用如下技术方案:
[0007] 提供一种提高HDPE结构壁管表面光泽度的模具，其为采用内压法的管坯挤压成型模具，其挤出模具部分包括芯棒、芯棒外套有外口模，在芯棒与外口模端部共同安装有一个外模板法兰，其特征在于:所述的外模板法兰与外口模、芯棒之间镶嵌安装有一个与芯棒同心的聚四氟乙烯套，聚四氟乙烯套在芯棒外置处与外模板法兰之间安装有与芯棒同轴的内模压板。
[0008]作为优选实例，所述的外模板法兰上均布有定位销。
[0009] 本实用新型与现有技术相比，其有益效果为:其通过在挤出模具前镶嵌一块同心的聚四氟乙烯套来提高HDPE结构壁管表面光泽度，统一产品外观色度，结构简单、使用方便、成本投入低。
附图说明
[0010]图1是本实用新型的结构示意图。
[0011]图中编号:I为定位销，2为内模压板，3为聚四氟乙烯套，4为外模板法兰，5为外口模，6为芯棒。
具体实施方式
[0012] 为了使本实用新型实现的技术手段、创新特征、达成目的与功效易于明白了解，下面结合具体图示，进一步阐述本实用新型。
[0013] 一种提高HDPE结构壁管表面光泽度的模具，其为采用内压法的管坯挤压成型模具，其挤出模具部分包括芯棒6、芯棒6外套有外口模5，在芯棒6与外口模5端部共同安装有一个外模板法兰4，外模板法兰4与外口模5、芯棒6之间镶嵌安装有一个与芯棒6同心的聚四氟乙烯套3，聚四氟乙烯套3在芯棒6外置处与外模板法兰4之间安装有与芯棒6同轴的内模压板2。
