Description

浇铸模具 说明书
浇铸模具
技术领域
本发明涉及一种成型用模具，尤其是一种用于混凝土成型的浇铸模具。
背景技术
混凝土在建筑行业广泛应用，例如用于做腔体、柱体或其他有特定形状的混凝土制品。其中，有些混凝土制品在成型时需要用到模具。
一般来说，混凝土浇铸模具包括内模与外模，内模与外模之间形成有浇铸腔。制作混凝土制品时，将混凝土浆料灌注在浇铸腔内，待混凝土浆料硬化后即可形成混凝土浇铸成品。
然而，现有的浇注模具脱模时容易影响混凝土制品的质量，有时甚至会损坏混凝土制品。
发明内容
鉴于上述状况，有必要提供一种浇铸模具，其易于使产品脱模且可避免影响混凝土质量。
一种浇铸模具，包括内模与外模，该浇铸模具还包括保温材料层、固定板及脱出杆，其中该内模包括第一壳体，该第一壳体具有第一侧壁及与该第一侧壁相对的第二侧壁，且该第一壳体还具有第一开口、容纳腔及第二开口，该第一开口、该容纳腔及该第二开口之间相互连通用于允许流体通过；该保温材料层设于该第一侧壁上，该外模位于该第二侧壁外且与该第二侧壁间隔从而与该内模之间形成有一个浇注腔；该外模包括第二壳体以及位于该第二壳体内的加热元件；该固定板位于该内模与该外模的一端；该拉动元件设于该内模上。
该流体为液体或气体。
该液体为油或水。
该流体为温度低于室温的液体。
该加热元件为热电阻。
该加热元件与该第二壳体之间还填充有导热介质。
上述浇铸模具可通过外模与内模的热胀冷缩作用，对外模进行加热而在内模注入过冷流体，使得外模因过热而膨胀、内模因过冷而收缩进而与混凝土成品剥离，不会产生如现有技术中因拆解模具而伤害到混凝土成品的问题从而可提升产品的质量，并且不会影响混凝土成品的精度，混凝土成品脱模速度快又简单，因此还可降低成本。
附图说明
图 1 是本发明实施例的浇铸模具的剖面示意图。
图 2 是图 1 所示浇铸模具使用时的示意图。
图 3 是图 1 所示的浇铸模具的混凝土成品脱模时的示意图。
具体实施方式
下面将结合附图及实施例对本发明的浇铸模具作进一步的详细说明。
请参见图 1 ，本发明实施例的浇铸模具 10 包括外模 11 、内模 12 、保温材料层 13 、固定板 14 及脱出杆 15 。内模 12 为中空腔体结构。内模 12 内模具有容纳腔 122 、第一开口 124 与第二开口 126 。容纳腔 122 、第一开口 124 与第二开口 126 之间相互连通用于允许流体 18 从第一开口 124 进入内模 12 的容纳腔 122 而后再从第二开口 126 排出，如图 2 所示。内模 12 还包括第一侧壁 127 及与第一侧壁 127 相对的第二侧壁 128 。保温材料层 13 设于内模 12 的第一侧壁 127 上。外模 11 位于内模第二侧壁 128 外且与第二侧壁 128 间隔从而与内模 12 之间形成有一个浇注腔 16 。外模 11 包括第二壳体 112 以及位于第二壳体 112 内的加热元件 114 。固定板 14 位于内模 12 与外模 11 的一端。脱出杆 15 设于内模 12 上。
具体在本实施例中，流体可为温度低于室温的液体或气体，并且当流体为液体时，其可为水或油。流体在脱模产品时，用于冷却内模 12 ，以使内模 12 收缩与产品分离。第一开口 124 与第二开口 126 均可靠近固定板 14 ，并穿过固定板 14 与外部相接。
加热元件 114 可为热电阻，其用于加热外模 11 。较佳的，第二壳体 112 内还具有导热介质 116 ，而加热元件 114 则浸入在导热介质 116 中。第二壳体 112 可将导热介质 116 与加热元件 114 封闭在其中。导热介质 116 可由导热系数较高的材料构成。加热元件 114 在脱模产品时，用于加热外模 11 ，以使外模 11 膨胀。为使加热元件 114 具有较好的加热效果，加热元件 114 可均匀分布在导热介质 116 内。
请参见图 2 ，使用时，将混凝土浆料注入到浇注腔 16 ，待混凝土浆料硬化形成混凝土成品 17 后；将温度低于混凝土成品 17 的流体 18 从第一开口 124 注入容纳腔 122 ，让内模 12 过冷收缩而与混凝土成品 17 相分离；而在外模 11 内，加热元件 114 通电加热，让外模 11 过热膨胀而与混凝土成品 17 相分离；然后，通过脱出杆 15 将内模 12 取出，再将混凝土成品 17 取出，如图 3 所示。
由上可见，本发明实施例的浇铸模具 10 可通过外模 11 与内模 12 的热胀冷缩作用，对外模 11 进行加热而在内模 12 中注入过冷流体，使得外模 11 因热而膨胀、内模 12 因过冷而收缩进而与混凝土成品 17 相剥离，不会产生如现有技术中因拆解模具而伤害到混凝土成品 17 的问题从而可提升了产品的质量，并且不会影响混凝土成品 17 的精度，混凝土成品 17 脱模速度快又简单，因此还可降低成本。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明 , 任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
