Abstract

一种方形单壁波纹管的成型模具，采用分体式模具结构，在模具体1上铣出方孔1a，车出半圆环槽1b，再用压块3将加工好的镶环2压装在模具体1的半圆环槽1b内，组成了方形单壁波纹管的外形。这种分体式结构与现在的整体式结构相比，加工工艺更简单，生产工期更短，适合批量生产。在模具体1上还设置有真空通道，密封装置，敞开式淋水冷却通道，来实现对方形单壁波纹管的真空定型，冷却。使用了此种结构的成型模具，真空定型好，冷却速度快，生产出的方形单壁波纹管各项向能稳定，外观品质好，耗能低，节省生产成本。

Description

方形单壁波纹管成型模具
技术领域
本发明涉及一种波纹管成型模具，尤其涉及一种方形单壁波纹管成型模具。
背景技术
随着我国的城市化建设的不断推进，对城市使用的高压电缆埋地的需求不断加大，方形单壁波纹管作为高压电缆埋地的防护管，不仅耐温、耐压、防水、防老化，还能够多根电缆集中铺设，减少占地，节省施工成本。方形单壁波纹管适合多组管路集中铺设，管子之间接触紧密，抗压能力强，开挖空间小，施工操作简单，经济效益可观。目前生产方形单壁波纹的模具采用的整体式加工，加工难度大，真空通道狭窄，生产出的产品外观质量差，因此需要设计一种加工成本低，真空定型稳定，冷却快的新模具。
发明内容
本发明的目的在于设计一种结构简单，真空定型稳定，冷却快，加工工艺性好的方形单壁波纹管成型模具。
本发明的技术方案是：在模具体上铣出方孔，车出半圆环槽，再用压块将加工好的镶环压装在模具体的环槽内，组成了方形单壁波纹管的外形。在模具体加工出真空通道，在镶环上开出真空槽共同组成了真空系统，实施容易，真空通道空间大，真空效果好，使挤出的料胚在真空下定型饱满。而整体式模具的真空通道是用片铣刀加工出来的，只有0.5mm宽，5mm深的一个环槽，真空通道狭小，真空效果不如分体式模具。在模具体的正面和侧面加工密封槽，镶上密封胶条，进一步保证了真空度。利用模具体背面和水板组成的冷却空腔，将冷却水淋在空腔内，对模具进行冷却，水碗保证模具之间不漏水
这种分体式结构与现在的整体式结构相比，加工工艺更简单，生产工期更短，适合批量生产。此种结构的方形单壁波纹管成型模具，真空定型好，冷却速度快，生产出的方形单壁波纹管各项向能稳定，外观品质好，耗能低，节省生产成本。
附图说明
图1是方形单壁波纹管的外形图
图2是本发明方形单壁波纹管成型模具的结构示意图；
图3是本发明方形单壁波纹管成型模具的另一方向的结构示意图；
图4是本发明模具体的结构示意图；
图5是本发明镶环的结构示意图。
具体实施方式
下面结合附图对本发明作进一步说明。
如图2和图3所示为本发明方形单壁波纹管成型模具结构形式。采用分体式模具结构，在模具体1上铣出方孔1a，车出半圆环槽1b（参看图4）再用压块3将加工好的镶环2（参看图5）压装在模具体1的半圆环槽1b内，组成了方形单壁波纹管的外形。这种分体式结构与现在的整体式结构相比，加工工艺更简单，生产工期更短，适合批量生产。在模具体1加工出真空通道，在镶环2上开出真空槽共同组成了真空系统，此模具的真空系统实施容易，真空通道空间大，真空效果好，使挤出的料胚在真空下定型饱满，而整体式模具的真空通道是用片铣刀加工出来的，只有0.5mm宽，5mm深的一个环槽，真空通道狭小，抽真空效果不如分体式模具。在模具体的正面和侧面加工密封槽，镶上密封胶条，进一步保证了方形单壁波纹管成型时的真空度。利用模具体1背面和水板6组成的冷却空腔，将冷却水淋在空腔内，对模具进行冷却，水碗5保证模具之间不漏水。与现在普遍采用的密闭水冷相比，敞开式临水冷却是在常压下进行的，结构简单，不易漏水，能将模块的温度控制在适合生产的温度，同时降低了模具的加工成本。
这种分体式结构与现在的整体式结构相比，加工工艺更简单，生产工期更短，适合批量生产。此种结构的方形单壁波纹管成型模具，真空定型好，冷却速度快，生产出的方形单壁波纹管各项向能稳定，外观品质好，耗能低，节省生产成本。
最后应说明的是：虽然以上描述了本发明的具体实施方式，但是本技术领域的普通技术人员应当理解，这些仅是举例说明，可以对这些具体实施方式做出多种变更或修改，而不背离本发明的原理和实质，本发明的保护范围由权利要求书限定。
