Description

汽车安全座椅的制造方法
技术领域
本发明涉及一种汽车安全座椅的制造方法，尤其涉及一种无需在本体上设置座布或垫体的制造方法。
背景技术
汽车安全座椅也称为儿童安全座椅，是幼儿在乘车时所必须使用的安全保护装置。现有技术中，汽车安全座椅的制造方法是先成型好本体，然后在本体上设置座布或垫体。其中，本体是利用聚丙烯(PP)等热塑性塑料以射出成型方式在一射出模中形成，其成型后质地较硬，因此需加设座布或垫体来提高汽车安全座椅的舒适性与安全性，以供幼儿乘坐。但是，为了将座布或垫体固定在本体上，本体需增设相关固定机构，这种配置存在增加成本与组装时间的问题。
为解决上述问题，有必要提供一种无需设置座布或垫体，同时又能够保障舒适性与安全性的汽车安全座椅制造方法。
发明内容
本发明的目的在于提供一种无需设置座布或垫体，同时又能够保障舒适性与安全性的汽车安全座椅制造方法。
为了实现上述目的，本发明提供了一种汽车安全座椅的制造方法，包括以下步骤：提供一模具，将汽车安全座椅的本体放入模具中，在模具的型腔中注入发泡材料进行发泡，使本体上一体成型一包覆本体的可挠性层，发泡时型腔内的压力为1.5-5.0bar。
与现有技术相比，由于本发明的制造方法将本体放入模具之中并利用发泡成型直接在本体上形成可挠性层，由可挠性层来保障汽车安全座椅的舒适性与安全性，无需在本体上设置固定机构与座布或垫体，能够节省成本与组装时间。另外，在省去固定机构后，汽车安全座椅的整体重量得以减小。
较佳地，发泡时型腔内的压力为2.0-4.0bar。
较佳地，发泡后的的平均发泡颗粒直径为1-10mm。
较佳地，本体的壁厚为1.5mm。
较佳地，注入发泡材料后，向型腔中通入蒸汽，利用温度与压力使发泡材料结合。
较佳地，可挠性层成型后，先进行冷却，然后将模具开模，利用顶针顶出或人工取出包括本体与可挠性层的汽车安全座椅。
具体地，取出汽车安全座椅后，对其进行烘干与冷却。
更具体地，冷却汽车安全座椅后，对其进行削除毛边处理。
更具体地，在烘干汽车安全座椅前，先将定型治具放入汽车安全座椅，以协助定型。
较佳地，在将本体放入模具之前，在本体上放入封闭治具，以封闭本体上的孔或槽。

具体实施方式
下面结合给出的说明书附图对本发明的较佳实施例作出描述。
如图1、图2所示，本实施例提供了一种汽车安全座椅的制造方法，针对已经成型好的PP本体11进行二次成型，从而制造出汽车安全座椅1，无需在本体11上设置座布或垫体，本制造方法包括以下两个主要步骤：提供一模具，将本体11放入模具中并合模；在模具的型腔中注入发泡材料进行发泡，使本体11上一体成型一包覆本体11的可挠性层12。
将发泡材料注入型腔中后，向型腔内通入高温蒸汽，使型腔中具有一定温度与压力，在温度与压力的共同作用下发泡材料能够发泡并结合到本体11上。发泡时型腔中的压力应在1.5-5.0bar的范围内，较佳地，可设定为2.0-4.0bar。发泡成型完成后，需使汽车安全座椅1在模具中冷却一定时间，然后才可将汽车安全座椅1从模具中取出。本体11的壁厚大致为1.5mm，在将本体11放入模具中时，应确保本体11与模具的内壁之间的间隙不可过大，以免本体11变形。
在发泡过程中，主要的制程条件有四个：压力、蒸汽温度、发泡倍率以及冷却时间。通过设定不同的制程条件，得到以下表格中9个不同的发泡成型样品。
由以上表格可以看出，当型腔中压力过小(低于1.5bar)时，材料无法发泡，而当型腔中压力过大(高于6bar)时，则发泡过度，颗粒萎缩，且同时会造成本体11过压变形。因此本实施例中采用的压力范围值在1.5-5.0bar之间，取2.0-4.0bar更佳。
另外，发泡倍率与平均发泡颗粒直径这两个参数会影响到成型后汽车安全座椅1的质量。当发泡倍率低于30时会使整体成品的质量过重，而如果发泡倍率高于50，则整体成品质量轻但耐冲击性能太差。如需制造轻量型汽车安全座椅1，平均发泡颗粒直径应当在1-10mm的范围内。这一平均发泡颗粒直径是取1立方厘米内每个发泡颗粒进行直径测量后得到的平均值。具体的，本实施例中采用的发泡材料为聚丙烯塑料发泡材料(EPP)。
如图3所示，本发明汽车安全座椅的制造方法的详细步骤如下：
提供一模具，将本体11放入模具中并合模；
在模具的型腔中注入发泡材料；
向型腔中通入高温蒸汽，利用温度与压力使发泡材料结合到本体11上，形成包覆于本体11的可挠性层12；
冷却；
模具开模，利用顶针顶出或人工取出汽车安全座椅1；
对汽车安全座椅1进行烘干，然后冷却；
对汽车安全座椅1进行削除毛边处理。
完成上述步骤后，汽车安全座椅1的制造完成，可进行包装。
本体11上存在有许多孔或槽，如将本体11直接放入模具中进行发泡成型，则该些孔或槽将会被发泡材料填满。为避免发泡材料填入，可先使用封闭治具将本体11上希望保留的孔或槽暂时封闭，然后才将本体11放入到模具中进行发泡。封闭治具是形状与孔或槽的形状对应的塞子。
在汽车安全座椅1出模后的烘干步骤中，受热量影响，本体11可能出现一些变形，而本体11上的孔、槽或沟等凹陷处是较容易变形的位置。为避免此种情况，可在烘干前先使用定型治具插入这些凹陷处以对这些位置进行辅助定型，然后才对汽车安全座椅1进行烘干。烘干过程中由于定型治具支撑、定型于凹陷处，能够有效避免变形。定型治具是形状与凹陷处的形状对应的塞子。
与现有技术相比，由于本发明的制造方法将本体11放入模具之中并利用发泡成型直接在本体11上形成可挠性层12，由可挠性层12来保障汽车安全座椅1的舒适性与安全性，无需在本体11上设置固定机构与座布或垫体，能够节省成本与组装时间。另外，在省去固定机构后，汽车安全座椅的整体重量得以减小。
以上所揭露的仅为本发明的较佳实例而已，其作用是方便本领域的技术人员理解并据以实施，当然不能以此来限定本发明之权利范围，因此依本发明申请专利范围所作的等同变化，仍属于本发明所涵盖的范围。
