Abstract

本实用新型涉及挤塑机装备领域，尤其涉及一种提高管材整形度的挤塑机出料模具，包括外层口模及设于口模内与其配合的芯棒，所述芯棒前端水平延伸到与口模同齐位置，在芯棒的水平延伸段设有包裹水平延伸段的隔温套，所述隔温套壁厚为0.3mm-0.5mm。由于在芯棒的水平延伸段设有包裹水平延伸段的隔温套，所述隔温套壁厚为0.3mm-0.5mm，在原料以熔融状态通过口模与芯棒之间时，在管材的定径阶段，即芯棒自口模内部缩径至所需输出内径后，管材内径通过与隔温套摩擦提高管材内径的整形度，且当使用隔温套包裹芯棒的水平延伸段时，能够使管材逐渐的降温，并有效的提高出管效率。

Description

一种提高管材整形度的挤塑机出料模具
技术领域
本实用新型涉及挤塑机装备领域，尤其涉及一种提高管材整形度的挤塑机出料模具。
背景技术
挤塑机是生产塑料管材的必要设备，其作用是将原料融化后挤出，而后通过挤塑机出料模具及冷却设备，将产品定型。现有的挤塑机出料模具包括外层口模及设于口模内与其配合的芯棒，芯棒为半径逐渐减小的，并至口模同齐位置保持小内径挤出的内径定型模具，目前芯棒自口模内部缩径至所需输出内径后保持水平延伸的平滑状态，此种芯棒不能做到管材内径的良好整形。
实用新型内容
本实用新型所要解决的技术问题是克服现有技术中存在的不足，提供一种提高管材整形度的挤塑机出料模具。
本实用新型是通过以下技术方案予以实现：
一种提高管材整形度的挤塑机出料模具，包括外层口模及设于口模内与其配合的芯棒，所述芯棒前端水平延伸到与口模同齐位置，在芯棒的水平延伸段设有包裹水平延伸段的隔温套，所述隔温套壁厚为0.3mm-0.5mm。
本实用新型的有益效果是：
由于在在芯棒的水平延伸段设有包裹水平延伸段的隔温套，所述隔温套壁厚为0.3mm-0.5mm，在原料以熔融状态通过口模与芯棒之间时，在管材的定径阶段，即芯棒自口模内部缩径至所需输出内径后，管材内径通过与隔温套摩擦提高管材内径的整形度，且当使用隔温套包裹芯棒的水平延伸段时，能够使管材逐渐的降温，并有效的提高出管效率。
附图说明
图1是本实用新型的主视结构示意图。
图2是本实用新型的侧视结构示意图。
图中：1.挤塑机，2.口模，3.隔温套，4.芯棒，5.水平延伸段。
具体实施方式
为了使本技术领域的技术人员更好地理解本实用新型的技术方案，下面结合附图和最佳实施例对本实用新型作进一步的详细说明。
如图1所示，本实用新型安装在挤塑机1前端，包括外层口模2及设于口模内与其配合的芯棒4，所述芯棒前端水平延伸到与口模同齐位置，在芯棒的水平延伸段5设有包裹水平延伸段的隔温套3，所述隔温套壁厚为0.3mm-0.5mm。
由于在在芯棒的水平延伸段设有包裹水平延伸段的隔温套，所述隔温套壁厚为0.3mm-0.5mm，在原料以熔融状态通过口模与芯棒之间时，在管材的定径阶段，即芯棒自口模内部缩径至所需输出内径后，管材内径通过与隔温套摩擦提高管材内径的整形度，且当使用隔温套包裹芯棒的水平延伸段时，能够使管材逐渐的降温，并有效的提高出管效率。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
