Description

PU扶手发泡模成型模具 技术领域
本实用新型涉及PU扶手发泡模成型领域，具体涉及一种PU扶手发泡模成型模具。
背景技术
以往PU扶手发泡模成型模具是两片式，上模具和下模具，水平开模，这样模具在制造PU扶手时产生的气泡会集中在产品上表面，质量就会达不到设计要求，不能满足客户需求。
发明内容
为了解决上述发明问题，本实用新型提出了一种PU扶手发泡模成型模具，设计简单，使用方便，解决了气泡问题，提高了产品质量，满足了客户要求。
为了达到上述发明目的，本实用新型提出了以下技术方案：
PU扶手发泡模成型模具，它包括底座、下模具、斜模具、上模具，底座上面装有下模具，下模具的型腔是倾斜状，下模具侧上方装有斜模具，下模具和斜模具上端装有上模具。
所述的下模具一侧装有气缸，气缸下端固定在下模具一侧，气缸上端连接在斜模具中间一侧。
所述的斜模具下端设计有销管，下模具一侧上端装有U型状销管，斜模具的销管插在下模具的U型状销管中间且通过转轴插接一起。
所述的上模具一端装有销孔，下模具一侧上端装有销孔，上模具的销孔与下模具的销孔通过转轴连接一起。
所述的上模具的背面设计有加热水管。
所述的下模具型腔背面设计有加热水管。
所述的斜模具型腔背面设计有加热水管。
本实用新型的优点是设计简单，使用方便，模具型腔倾斜设计，气泡全部上升到产品右上角位置，气泡全部集中在一起，对产品影响降低到最低，产品质量大大提高，符合客户要求。
附图说明
图1是本实用新型的示意图。
图2是本实用新型的剖视图。
图3是本实用新型的爆炸示意图。
具体实施方式
为了对本实用新型进一步说明，下面结合说明书附图来介绍：
参照附图，PU扶手发泡模成型模具，它包括底座1、下模具2、斜模具3、上模具4，底座1上面装有下模具2，下模具2的型腔是倾斜状，下模具2侧上方装有斜模具3，下模具2和斜模具3上端装有上模具4。
所述的下模具2一侧装有气缸5，气缸5下端固定在下模具2一侧，气缸5上端连接在斜模具3中间一侧。气缸设计用来打开斜模具的。
所述的斜模具3下端设计有销管6，下模具2一侧上端装有U型状销管7，斜模具的销管6插在下模具的U型状销管7中间且通过转轴8插接一起。此设计是为了斜模具在油缸推动下，可以通过转轴翻转打开。
所述的上模具4一端装有销孔9，下模具一侧上端装有销孔10，上模具的销孔9与下模具的销孔10通过转轴8连接一起。这样设计上模具可以通过转轴翻转打开。
所述的上模具4的背面设计有加热水管11。
所述的下模具2型腔背面设计有加热水管12。
所述的斜模具3型腔背面设计有加热水管14。
本实用新型使用时，本装置外侧装有一个上模具开模机架，用来把上模具打开，首先上模具开模机架把上模具打开，通过气缸把斜模具也打开，然后向上模具、下模具、斜模具中喷洒脱模剂，气缸把斜模具也闭合后向型腔内投放发泡剂，再把上模具关闭，加热水管内通入65度热水开始加热，发泡剂开始膨胀发泡，由于气体轻，所以气体都上升到型腔右上角，其他地方就不会分布有气泡，这样产品总体质量就会上升，符合客户要求，等发泡剂发泡结束后，停止加热，打开上模具，气缸把斜模具打开取出产品13进行自然冷却。
