Description

发泡结构件、树脂制面板
本申请是申请日为2013年11月21日、发明名称为“发泡结构件、树脂制面板、树脂制面板的制造方法”、申请号为201380063558.8(PCT/JP2013/081431)的中国发明专利申请的分案申请。
技术领域
本发明涉及发泡结构件、以及用表皮材料片覆盖该发泡结构件的树脂制面板及其制造技术。
背景技术
以往，树脂制面板被用于汽车、航空器等运输机械用、建材用、电气设备的外壳用、运动/娱乐用等多个用途。虽然树脂制面板是用表皮材料片覆盖芯件的树脂制面板，但是，存在用表皮材料片仅覆盖芯件的一个面的树脂制面板、和用表皮材料片覆盖芯件的两个面的树脂制面板。用表皮材料片仅覆盖芯件的一个面的树脂制面板例如被用于建材用等由于不会被使用者看到而无需用表皮材料片覆盖芯件的另一个面的用途等。用表皮材料片覆盖芯件的两个面的树脂制面板也被称作夹层面板。树脂制面板具有：两张表皮材料片和夹在两张表皮材料片之间的芯件。即，在树脂制面板中，表皮材料片、芯件和表皮材料片的层叠结构是基本形式。
以往，已知有将金属制的加强件嵌入到作为芯件的树脂发泡体的树脂制面板。例如，在日本特开2010-174577号公报中公开了如下树脂制面板：将内装件内装在中空双层壁结构的中空部中，从而，能够准确地进行内装的内装件的定位，不会引起由于防止松动或成型收缩导致的变形，其中，该内装件将加强件嵌合到由热塑性树脂构成的芯件而使芯件与加强件成为一体，该芯件被预成型为与中空部内的空间大致相同的形状。
发明内容
发明所要解决的问题
芯件与加强件成为一体的现有的树脂制面板用内装件(发泡结构件)是将加强件嵌合到作为芯件的2个发泡体之间的结构，该2个发泡体使用基本上相同的成型装置进行成型。但是，即使在该情况下，有时也会发生以不同批次、或者不同状况(装置的动作状态或装置内以及周围的环境条件)成型的情况，从成型装置中取出后的各个发泡体的体积变化不同。如果各个发泡体的体积变化不同，则其后在将2个发泡体嵌合到加强件时，由于仅一个与加强件之间的间隙相对增大等，导致制作成树脂制面板时的美观性变差。美观性变差的情况的一例是树脂制面板的面并不在整个区域内平坦，而是局部隆起等的情况。
本发明正是鉴于上述方面而完成的，其目的在于：在制造芯件与加强件成为一体的发泡结构件和树脂制面板时，相比以往提高将芯件嵌合到加强件时的精度；以及提供提高了精度的发泡结构件以及树脂制面板。
用于解决问题的手段
本发明的第1观点是发泡结构件。
该发泡结构件包括：第1芯件和第2芯件，该第1芯件和第2芯件是将设置有直线形的槽部的发泡体在所述槽部处割断而成的，该槽部用于嵌合加强件；以及加强件，第1芯件和第2芯件分别从所述加强件的一侧和另一侧嵌合于该加强件。
本发明的第2观点是用表皮材料片覆盖上述发泡结构件的树脂制面板。
本发明的第3观点是用表皮材料片覆盖发泡结构件的树脂制面板的制造方法。
该树脂制面板用的制造方法包括如下工序：将设置有直线状的槽部的发泡体在所述槽部处割断而分割成第1芯件和第2芯件，其中，该槽部用于嵌合加强件；将第1芯件和第2芯件分别从所述加强件的一侧和另一侧嵌合到该加强件，组装芯件与加强件成为了一体的发泡结构件；以及将作为表皮材料片的树脂片熔敷到所述发泡结构件。

具体实施方式
以下，说明本发明的树脂制面板、树脂制面板用内装件以及它们的制造方法的一个实施方式。
(1)树脂制面板以及树脂制面板用内装件
如图1所示，实施方式的树脂制面板1的外形由正面1a和背面1b、以及介于在正面1a和背面1b之间的侧壁面1c构成。正面1a、背面1b以及侧壁面1c由热塑性树脂的树脂片SA、SB构成，在它们内部内装有内装件10。即，树脂制面板1是由热塑性树脂的树脂片SA、SB夹入内装件10的夹层结构。内装件10是发泡结构件的一例。
虽然在实施方式的树脂制面板1中，作为表皮材料片的树脂片SA、SB未对该树脂材料进行限定，但是为了确保树脂制面板1的刚性，优选由非发泡树脂形成。例如，考虑成型性，树脂片SA、SB也可以在作为主材料的聚丙烯(PP)中混合聚苯乙烯(PS)和苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物树脂(SEBS)。
如图2所示，内装件10是如下的复合结构体：分别将作为树脂发泡体的芯件21、22嵌合到加强件30的一侧和另一侧，使芯件21、22与加强件30成为一体。加强件30是与芯件21、22的端部同等程度的长度的长条状的部件。本实施方式的加强件30的截面形状为H形的部件(所谓的H形挤压加固件)，但是加强件30的形状不限于此。加强件30的截面形状例如可以是C形、コ字形、方管状或者圆管状等，只要是能够与芯件21、22嵌合为一体的形状就适合。加强件30优选是铝等金属制或者硬质的塑料制的。
芯件21、22的厚度根据作为树脂制面板1的目标厚度、进而根据用于确保树脂制面板1的目标刚性的树脂片的厚度进行适当确定，并没有特别限定。
在实施方式的树脂制面板1中，芯件21、22使用例如热塑性树脂成型。虽然未限定该树脂材料，但是，例如包括：聚丙烯、聚乙烯等聚烯烃、或聚酰胺、聚苯乙烯、聚氯乙烯等丙烯酸衍生物的任意一个、或者两种以上的混合物。芯件21、22占树脂制面板1的体积的比例大，为了轻量化，优选是使用发泡剂进行发泡的发泡树脂，但是发泡倍率没有特别限定。
在实施方式的树脂制面板1中，作为能够用于芯件21、22的发泡剂，可以举出公知的物理发泡剂、化学发泡剂及其混合物。例如，作为物理发泡剂，能够使用空气、二氧化碳、氮气等无机系物理发泡剂；以及丁烷、戊烷、己烷、二氯甲烷、二氯乙烷等有机系物理发泡剂。此外，作为化学发泡剂，例如，可以举出偶氮二甲酰胺(ADCA)、N，N’-二亚硝基五亚甲基四胺、4，4’-氧双(苯磺酰肼)、二苯砜-3，3’-二磺酰肼、对甲苯磺酰基氨基脲、三肼基三嗪或偶氮二异丁腈等有机发泡剂；作为无机发泡剂可以举出柠檬酸、草酸、富马酸、邻苯二甲酸、苹果酸、酒石酸、环己烷-1，2-二羧酸、樟脑酸、乙二胺四乙酸、三亚乙基四胺六乙酸、次氮基三乙酸等多元羧酸、和碳酸氢钠、碳酸氢钠铝、碳酸氢钾、碳酸氢铵、碳酸铵等无机碳酸化合物的混合物、柠檬酸二氢钠、草酸钾等多元羧酸的盐。
树脂片SA、SB和芯件21、22以增加刚性和强度为目的，可以使用混入了玻璃填料的树脂材料进行成型。
作为玻璃填料，可以举出玻璃纤维、玻璃布或玻璃无纺布等玻璃纤维布、玻璃珠、玻璃薄片、玻璃粉末、磨碎玻璃等。作为玻璃的种类，可以举出E玻璃、C玻璃、A玻璃、S玻璃、D玻璃、NE玻璃、T玻璃、石英、低介电常数玻璃、高介电常数玻璃等。
另外，不限于玻璃填料，也可以混入用于提高刚性的滑石、碳酸钙、硅灰石(Wollastonite)、镁系材料等无机填料、碳纤维等。
(2)内装件10及其制造方法
接着，参考图3～图10，说明本实施方式的内装件10及其制造方法。
图3是实施方式的内装件10的作为芯件21、22的发泡体20的立体图。图4A和图4B是用于依次说明成型图3所示的发泡体20的工序的图。图5是实施方式的内装件10的作为芯件21、22的发泡体20的俯视图。图6示出图5所示的A-A、B-B、C-C、D-D的剖面。图7是图5所示的E部的放大立体图。图8是示出对实施方式的内装件10进行组装的工序的图。图10是实施方式的内装件10的与图5的B-B相应的位置处的剖面图。
(2-1)作为芯件的坯料的发泡体
本实施方式的芯件21、22是通过对作为一体件被成型出的发泡体20进行割断而制作而成的。如图3所示，发泡体20的外形由正面20a和背面20b、以及夹在正面20a和背面20b之间的侧壁面20c构成。
如图3所示，在发泡体20的正面20a从一端到另一端形成有直线状的槽部230。另外，在发泡体20的背面20b也与正面20a相同地形成有槽部230。槽部230是为了对发泡体20进行割断并且在割断后嵌合加强件30而设置的。关于槽部230之后将详细叙述。
(2-2)作为芯件的坯料的发泡体的成型
发泡体20使用图4A和图4B所示的成型装置50通过珠(baeds)法模内发泡成型法成型。如图4A的S1所示，在成型装置50上设置有对置配置的模具51、52。模具51、52分别构成空室53、54的一部分。在空室53、54中配设有冷却管41、42。
当从图4A的S1所示的状态关闭模具51、52时，如图4A的S2所示，形成型腔50a，该型腔50a是由模具51、52构成的密闭空间。在关闭了模具51、52的状态下，通过加料器43、44填充发泡珠。被填充的发泡珠的量例如为型腔50a的容积的105～110％。接着，如图4B的S3所示，从蒸汽注入口55、56向空室53、54注入蒸汽(例如蒸汽压力为3.0kgf/cm2～3.5kgf/cm2)例如10秒～30秒。蒸汽从被形成在模具上的微孔进入到发泡珠内的气泡及彼此之间的空隙，使珠彼此热粘。其后，如图4B的S4所示，从冷却水注入口57、58向冷却管41、42注入冷却水，对模具51、52进行喷雾而使模具51、52和发泡体20冷却，从而使发泡体20固化。接下来，如图4B的S5所示，打开模具并取出发泡体20。然后，发泡体20被放置在例如50℃～70℃的房间中12～24个小时来进行养护从而促进固化，防止收缩(ヒケ)、变形。
(2-3)作为芯件的坯料的发泡体的详细形状的一例
接着，参考图5～7说明发泡体20的槽部230的详细形状。以下，虽然仅说明正面20a侧的槽部230，但是背面20b侧的槽部230也是相同的形状。另外，在本实施方式中，在假设了处于槽部230的中央的与正面20a垂直的面时，槽部230成为关于该面而对称的结构。
在槽部230中，以发泡体20的正面20a为基准，以规定的阶梯差量形成有卡合面211、221。如图5所示，卡合面211、221从发泡体20的正面20a的一端到另一端而形成在槽部230的整个区域。卡合面211、221是为了供截面形状为H形的加强件30(H形挤压加固件)卡合而由此将芯件21、22与加强件30嵌合为一体而设置的。只要在芯件21、22与加强件30嵌合为一体的状态下，正面20a与加强件30的上表面大致在同一平面上，则可以适当设定正面20a与卡合面211、221之间的阶梯差量。此外，卡合面211、221的宽度只要确保至少能够将加强件30卡合的长度即可。
如图5所示，沿着卡合面211、221所延伸的方向，分别形成有6处突起211a、221a，但是，突起211a、221a的个数只不过是一例，也不限于图示的个数。突起211a、221a以如下目的设置：在截面形状为H形的加强件30(H形挤压加固件)卡合时，提高在加强件30与卡合面211、221之间产生的面压，从而增大芯件21、22与加强件30的嵌合力。即，通过设置突起211a、221a，从而能够在将芯件21、22嵌合到加强件30之后，使芯件21、22很难在与卡合面211、221所延伸的方向垂直的方向上从加强件30脱离。
另外，虽然在图5和图6中示出了突起211a、221a在各处被设置在对置的位置的情况，但也不限于该情况。突起211a和突起221a也可分别设置在卡合面211和卡合面221上的相互独立的位置处。
突起211a、221a的高度、沿着卡合面211、221所延伸的方向的长度以及各突起的个数考虑下述内容而被适当设定：组装芯件21、22和加强件30时的作业性(即，进行嵌合时的力)、将芯件21、22嵌合到加强件30之后的脱离力。
在图5和图6所示的例子中示出了突起211a、221a分别形成在卡合面211、221的端部，但是，也不限于该例子。只要是在加强件30与卡合面211、221卡合的范围内，就能够提高在加强件30与卡合面211、221之间产生的面压，所以突起211a、221a即使没有形成在卡合面211、221的端部也没关系。
如图6中清晰可见，优选的是，在卡合面211、221之间，形成有槽深比较浅的浅槽230a以及槽深比较深的深槽230b而作为用于割断发泡体20的槽。在图5和图6所示的例子中，设置有11处浅槽230a和10处深槽230b。设置浅槽230a和深槽230b来作为用于割断发泡体20的槽的理由如下。即，在假设仅设置了深槽的情况下，在之后的工序中割断发泡体20的力较小即可，作业性得到提高，但是，在对发泡体20进行成型的工序中，由于与深槽相应的位置处的模具的型腔的通道窄，导致很难从加料器向型腔的整个区域填充发泡珠。另一方面，在假设仅设置了浅槽的情况下，在对发泡体20进行成型的工序中容易从加料器填充发泡珠，但是，在之后的工序中，割断发泡体20的力增大，作业性变差。因此，出于兼顾成型性和作业性的观点，设置浅槽230a和深槽230b。
另外，如图5所示，优选浅槽230a和深槽230b分别交替设置多个。这是因为：兼顾成型性和作业性，同时多个浅槽的位置沿着卡合面211、221所延伸的方向分散，所以发泡体20的割断位置的精度变得良好。
如图7所示，优选在图5的E部分、即槽部230的一端形成有用于在对内装件10进行组装之后防止加强件30的脱落的止挡部212、222。
另外，在图7所示的例子中，止挡部212、222与正面20a构成了同一平面，但不限于此。由于只要能够防止加强件30沿着其长度方向移动并脱落即可，所以，止挡部212、222无需必须与正面20a在同一平面，只要与加强件30所卡合的卡合面211、221相比向正面20a侧突出即可。
(2-4)发泡体的割断以及内装件的组装
接着，说明成型出发泡体20之后的工序。
在成型出发泡体20后，将发泡体20在槽部230的浅槽230a和深槽230b处进行割断，并分割成作为第1芯件和第2芯件的芯件21、22。接下来，如图8所示，分别从加强件30的一侧和另一侧嵌合芯件21、22，组装芯件21、22与加强件30成为了一体的内装件10。如图9所示，在内装件10上形成有突起211a、221a的部位处，芯件21、22相对于加强件30的面压升高，并且即使在芯件21、22分别向图中的右方向或左方向移动的情况下，加强件30的突起30a与芯件21、22的突起211a、221a抵接，芯件21、22不会从加强件30脱离。另外，如图10所示，也可以使用没有突起30a的加强件30。即使在该情况下，由于在芯件21、22的设置有突起211a、221a的位置处，与加强件30之间的面压会升高，所以芯件21、22也很难分别向图中的右方向或左方向脱离。
在本实施方式中，由于作为芯件21、22的坯料的发泡体20是使用同一成型装置而一体地成型的，所以即使由成型装置的动作状态、或成型装置内和周围的环境条件等导致产生了成型时的发泡体20的体积变化，对于以该发泡体20为坯件进行割断所得到的芯件21、22，等同于不存在与加强件30嵌合的部位的形状的差异。因此，在使芯件21、22与加强件30嵌合时，不易产生仅一个芯件与加强件30之间的间隙相对增大等由芯件的形状的不一致导致的问题。因此，在通过后述的树脂制面板的成型工序制作树脂制面板1时，不易产生例如树脂制面板的面并不在整个区域平坦而是局部隆起等美观性变差的情况。
(3)树脂制面板的成型方法
接着，参照图11～17，说明使用模具成型实施方式的树脂制面板1的装置和方法。
首先，说明实施方式的树脂制面板1的成型装置。
如图11所示，实施方式的成型装置90具有：挤压装置60、和配置在挤压装置60的下方的合模装置70。被从挤压装置60挤压出的熔融状态的树脂片P被送至合模装置70，将熔融状态的树脂片P在合模装置70中成型。另外，在图11中，在剖面图中仅示出合模装置70和熔融状态的树脂片P。
挤压装置60具有：T模(die)61A、61B、加压器81A、81B、柱塞82A、82B、挤压器83A、83B以及树脂加料斗84A、84B。在挤压装置60中，使用挤压器使树脂原料可塑化熔融，该熔融树脂被T模61A、61B挤压到模外。在挤压装置60中，挤压器83A、83B的挤压能力能够根据树脂制面板1的尺寸来适当选择，但是，从缩短树脂制面板1的成型周期的观点出发，优选为50kg/小时以上。
在挤压装置60中，树脂片的挤压速度由T模61A、61B和加压器81A、81B设定。此外，从防止刮涂的方面考虑，T模61A、61B中的树脂片的挤压优选在40秒以内完成，更优选在30秒以内完成。因此，储存在加压器81A、81B中的熔融树脂材料以平均1cm2为50kg/小时以上、优选60kg/小时以上的速度被从T模61A、61B中挤压。此时，与树脂片的挤压速度相应地改变T模61A、61B的模末端的缝隙，从而能够进一步抑制刮涂的影响。即，从开始挤压起慢慢扩大T模61A、61B的缝隙的间隔，在挤压结束时，达到最大，从而抑制由于树脂片的自重导致的壁厚变化，使树脂片在上下方向的大范围内形成均匀的厚度。由此，能够在使后述的一对分割模具从打开位置移动至关闭位置的时刻，使树脂片的厚度均匀。
再次参照图11，合模装置70具有一对分割模具71A、71B，该一对分割模具71A、71B在与熔融状态的树脂片P的供给方向大致垂直的方向上，在打开位置与关闭位置之间移动。一对分割模具71A、71B在使各自对应的形成面72A、72B对置的状态下配置。在形成面72A、72B的表面，也可以与树脂制面板1的大致外形相应地设置有凹凸部。
在一对分割模具71A、71B各自中，在各自对应的形成面72A、72B的上下端附近形成有夹断部74A、74B。该夹断部74A、74B分别绕形成面72A、72B形成为环形，并朝向对置的分割模具71B、71A突出。由此，在对一对分割模具71A、71B进行合模时，各自的夹断部74A、74B的前端部抵接，从而在熔融状态的树脂片P的周缘形成分型线PL。
在一对分割模具71A、71B中，在形成面72A、72B的周围，以能够从形成面72A、72B突出的方式设置有滑动部75A、75B。滑动部75A、75B被设置成，在从形成面72A、72B突出的状态下，其端面与树脂片P接触，由此，在树脂片P与一对分割模具71A、71B的形成面72A、72B之间形成密闭空间(型腔)。
在一对分割模具71A、71B中内置有真空腔室73A、73B。真空腔室73A、73B与真空泵和真空罐(均未图示)连接。在真空腔室73A、73B与形成面72A、72B之间设置有进行连通以用于型腔的真空抽吸的连通通道(未图示)。
一对分割模具71A、71B被模具驱动装置(未图示)驱动而能够在打开位置与关闭位置之间移动。在打开位置处，在一对分割模具71A、71B之间能够相互隔开间隔地配置有2张熔融状态的连续的树脂片P。2张树脂片P在成型后，成为树脂制面板1的树脂片SA、SB。在关闭位置处，一对分割模具71A、71B的夹断部74A、74B抵接，由此在一对模具71A、71B分别从打开位置移动至关闭位置时，在2个熔融状态的树脂分割模具71A、71B内形成型腔。另外，一对模具71A、71B被驱动而分别以朝向一对分割片P的中心线的位置移动。
接着，说明树脂制面板1的成型方法。
首先，如图11所示，从挤压装置60中，从各模缝隙向铅直下方挤出熔融状态的树脂片P。该被挤出的树脂片P分别通过辊65A、65B，而供给到一对分割模具71A、71B之间。在该时刻，一对分割模具71A、71B处于打开位置。
另外，在将装饰片(例如布制的装饰片)附加到树脂制面板1的表面的情况下，能够利用辊65A、65B将垂下的树脂片P和装饰片彼此压接。此时，虽然装饰片的内表面是布状，但是在加强与树脂片P的熔敷方面是优选。辊65A、65B在表面用氟薄膜实施涂布，并加热到70℃～100℃左右，这在防止树脂的附着和提高熔敷强度方面是优选。
此外，也可以预先将装饰片设置在分割模具的形成面，在树脂片P的成型的同时，使树脂片P熔敷到装饰片。
另外，作为布制的装饰片，优选无纺布。特别是，使用针刺无纺布在提高熔敷强度方面是优选，该针刺无纺布是刺入倒刺针而使纤维机械地结合而成的。
接着，如图12所示，使位于形成面72A、72B的周围的滑动部75A、75B突出，并使其端面与树脂片P接触。由此，在树脂片P与一对分割模具71A、71B的形成面72A、72B之间形成型腔。而且，利用设置在真空腔室73A、73B与形成面72A、72B之间的连通通道(未图示)，抽吸型腔内的空气。通过该抽吸，2张树脂片P分别被按压到一对分割模具71A、71B的形成面72A、72B上，如图13所示，被形成为沿着形成面72A、72B的形状、即，树脂制面板1的大致外形。
另外，构成为能够从位于形成面72A、72B的周围的滑动部75A、75B的前端抽吸树脂片P侧的空气，从而能够在与滑动部75A、75B接触的状态下牢固地保持树脂片P。此外，在抽吸型腔而将树脂片P形成为沿着形成面72A、72B的形状时，能够抑制发生褶皱。
接着，使用机械手(未图示)在一对分割模具71A、71B之间对内装件10进行定位，并如图14所示，以从侧方按压至一个分割模具(在图14中为分割模具71B)的方式进行插入。由此，内装件10熔敷到树脂片P。另外，虽然也由树脂材料构成，但是，树脂片P经过成型后的冷却而前后收缩1％。分割模具71A、71B的形成面72A、72B的形状是将该收缩估计在内而设定的。即，形成面72A、72B被设定为稍微大于树脂片的成型后的目标尺寸。因此，能够带余裕地将常温状态的内装件10插入到分割模具内。
接着，如图15所示，使一对分割模具71A、71B从打开位置移动至关闭位置而进行合模。由此，被熔敷到一个树脂片P(附图右侧)的内装件10也被熔敷到另一个树脂片P(附图左侧)。并且，在一对分割模具71A、71B的夹断部74A、74B处，一对树脂片P的周缘被熔敷起来而形成分型线PL。另外，在进行合模时，将预成型的常温状态的内装件10熔敷到熔融状态的树脂片P，所以，内装件10本身被预先定位而避免由于合模发生变形。
最后，使一对分割模具71A、71B再度移动至打开位置，使成型后的树脂制面板1从形成面72A、72B离开，通过切割器等对绕分型线PL形成的毛刺切断并去除。另外，也可以构成为在合模的同时由夹断部74A、74B切断毛刺。综上所述，层叠了树脂片SA、内装件10、树脂片SB的树脂制面板1完成。
另外，如上所述，以增加刚性和强度为目的，也可以在树脂片P中混入玻璃填料、无机填料或碳填料。
如上所述，根据在被挤出的熔融状态的树脂片固化之前被分割模具夹入并熔敷到内装件的方法，能够降低成型成本。这是由于，例如，与再次对固化了的树脂片进行加热而使其熔融并熔敷到内装件的方法相比，不需要再加热工序，能够降低成型成本。
此外，通过形成向铅直下方挤出熔融状态的树脂片的结构，能够减少制造装置的占有面积。这是由于，例如，在沿水平方向挤压并成型的情况下，另行需要用于使树脂片在水平方向上移动的输送装置，并且，需要在水平方向上与挤压装置并列设置该输送装置和模具。
另外，上述的实施方式的树脂制面板的成型方法也可以适当变形。以下，说明实施方式的树脂制面板的成型方法的变形例。
(变形例1)
在上述的树脂制面板的成型方法中，说明了一对T模挤压出熔融状态的树脂片的情况，但是，也能够通过对圆筒状的模坯进行切断并挤压来获得树脂片。
(变形例2)
在上述的树脂制面板的成型方法中，说明了在使一对分割模具71A、71B移动至关闭位置之前，在树脂片P与一对分割模具71A、71B的形成面72A、72B之间形成型腔的情况，但是不限于此。也可通过使一对分割模具71A、71B移动至关闭位置来形成型腔。
(变形例3)
在上述的树脂制面板的成型方法中，说明了为了将树脂片P按压到一对分割模具71A、71B的形成面72A、72B而抽吸型腔内部的空气的情况，但是不限于此。也可以通过向树脂片P吹送空气等流体来将树脂片P按压到一对分割模具71A、71B的形成面72A、72B(吹塑成型)。
(变形例4)
在上述的树脂制面板的成型方法中，说明了将熔融状态的树脂片的外层按压到分割模具的形成面的工序使用了从型腔进行抽吸的方法、或者吹塑成型的方法，但是不限于这些方法。也可以应用不形成腔室而是使用内装件10将熔融状态的树脂片按压至分割模具的腔室的方法。参照图16和图17对该方法进行说明。
图16是示出将内装件10按压至熔融状态的树脂片之前的状态的图。图17是示出相对于熔融状态的树脂片将内装件10按压至到达了分割模具的形成面之后的状态的图。
在本变形例的方法中，首先，如图16所示，在从挤压装置60向铅直下方挤出了熔融状态的树脂片P的状态(与图11相同的状态)下，由机械手120保持的内装件10被定位在隔着树脂片P与分割模具71B对置的位置。在内装件10被定位后，保持内装件10的机械手120朝向分割模具71B的形成面72B移动。于是，内装件10与熔融状态的树脂片P接触，内装件10与树脂片P熔敷。在与内装件10接触时，熔融状态的树脂片P由于未与热传导率高的分割模具71B接触，所以被保持在比较高的温度。这样，内装件10与树脂片P良好地进行熔敷。
当机械手120进一步移动使得树脂片P的外层到达分割模具71B的形成面72B时，成为图17所示的状态。此时，借助机械手120经由内装件10将树脂片P的外层按压至形成面72B。然后，从内装件10卸下机械手120。
以后的工序如上所述。
即，如图15所示，使一对分割模具71A、71B从打开位置移动至关闭位置而进行合模。由此，被熔敷到一个树脂片P(附图右侧)的内装件10也被熔敷到另一个树脂片P(附图左侧)。而且，一对树脂片被按压到分割模具71A、71B的形成面72A、72B，如图13所示，被形成为沿着形成面72A、72B的形状、即，树脂制面板1的大致外形。并且，在一对分割模具71A、71B的夹断部74A、74B处，一对树脂片P的周缘被熔敷而形成分型线PL。最后，使一对分割模具71A、71B再度移动到打开位置，使成型后的树脂制面板1从形成面72A、72B离开，用切割器等对绕分型线PL形成的毛刺进行切断并去除。综上所述，层叠了树脂片SA、内装件10、树脂片SB的树脂制面板1完成。
以上，详细说明了本发明的实施方式，但是，本发明的发泡结构件及其制造方法、以及树脂制面板及其制造方法不限于上述实施方式，当然能够在不脱离本发明主旨的范围内进行各种改良和变更。
例如，本发明的发泡结构件不限于用作树脂制面板的内装件的情况，能够不用树脂片覆盖发泡结构件，而是在原本的状态下用作增强部件、缓冲部件、隔热部件等。具体地说，也可以固定在由木材等形成的板材，或者通过该板材夹层来使用。
