本発明はマイクロ波硬化用鋳型の模型に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pattern for a microwave curing mold.
本出願人は先に樹脂材より成る模型材料で模型

製造法を出願した。 The applicant first makes a model using a model material made of a resin material, fills the model with a mold material made of a thermosetting resin or a thermoplastic resin and a refractory material containing a microwave-resistant dielectric material, and then We have filed an application for a mold manufacturing method in which the mold material is hardened by self-heating by irradiation with microwaves, and after hardening, the mold is cut out to manufacture the mold.
この鋳型の製造法における模型材料としてはシ
リコンゴム又はフツ素ゴムが用いられている。 Silicone rubber or fluorine rubber is used as the model material in this mold manufacturing method.
しかしこれ等の模型材料はマイクロ波エネルギ
ー損失が大きく繰り返し使用すると、熱変形が起
り、硬化鋳型の寸法精度が得られなくなるおそれ
がある。又、これ等の模型材料は高価であるた
め、肉厚を極力薄くしたいが、剛性が不足し変形
し易いので肉薄化は困難であるとの不具合を有す
る。 However, when these model materials have a large microwave energy loss and are used repeatedly, thermal deformation may occur, and the dimensional accuracy of the hardened mold may not be obtained. Furthermore, since these model materials are expensive, it is desirable to make the wall thickness as thin as possible, but the problem is that it is difficult to make the wall thickness thinner because the material lacks rigidity and is easily deformed.
本発明は上記の事情に鑑みなされたものであ
り、その目的は熱変形が少なく、剛性のある安価
なマイクロ波硬化用鋳型の模型を提供することで
ある。 The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a rigid and inexpensive mold model for microwave curing with little thermal deformation.
すなわち、シリコンゴム又はフツ素ゴムを表面

キシ樹脂にガラス繊維又はセラミツク質の混合物
を裏打ちした模型構造とすることで熱変形が少な
く、剛性のある安価な模型を得る事が出来た。 In other words, by using silicone rubber or fluorine rubber on the surface and lining the model with a mixture of glass fiber or ceramic material and styrene resin, acrylic resin, or epoxy resin, which has insulation properties, rigidity, and low microwave energy loss, We were able to obtain a rigid and inexpensive model with little thermal deformation.
以下図面を参照して実施例を説明する。 Examples will be described below with reference to the drawings.
模型1はシリコンゴムより成る表面層2(厚さ
10mm)の裏面にエポキシ樹脂90部とガラス繊維10
部の混合物より成る裏面層3を裏打ちした構造と
なつている。 Model 1 has a surface layer 2 made of silicone rubber (thickness
10mm) 90 parts epoxy resin and 10 parts glass fiber on the back side
It has a structure in which it is lined with a back layer 3 made of a mixture of
4は鋳型となる誘電物質1%を含有したシエル
砂である。 4 is shell sand containing 1% of a dielectric material which serves as a mold.
このような模型とすることで、シリコンゴムの
使用量を1/5に節減でき安価となると共に、模型
表面層2の熱変形が最小限に抑えることができ、
さらには中子取り模型の剛性が向上された。 By making such a model, the amount of silicone rubber used can be reduced to 1/5, making it cheaper, and the thermal deformation of the model surface layer 2 can be minimized.
Furthermore, the rigidity of the core model was improved.
第2図は他の実施例を示すもので、表面層2を
3mm、裏面層3をセラミツク質成型物とし、シエ
ル砂4を炭化砂50%を含有したシエル砂とした。
本発明は前述のように構成したので、熱変形が少
なく、剛性のある安価なマイクロ波硬化用鋳型の
模型を得ることができる。 FIG. 2 shows another example in which the surface layer 2 was 3 mm, the back layer 3 was a ceramic molded product, and the shell sand 4 was shell sand containing 50% carbonized sand.
Since the present invention is constructed as described above, it is possible to obtain a rigid and inexpensive microwave curing mold model with little thermal deformation.
