どの問題がある。 On the other hand, with the recent trend towards more upscale living, washbowls made of artificial marble and washbowls with counters in which the counter top and washbowl are integrally formed of artificial marble have been in the spotlight. In order to provide the above-mentioned water return part on such an artificial marble bowl, it is necessary to split the mold, and the parting line of the split mold remains on the surface of the product. Therefore, in addition to requiring complicated work such as smooth finishing in the subsequent process, the appearance of the finished part will be different from other parts, so conventionally, artificial marble bowls with a water return part were not manufactured in the same way. do not have. Therefore, conventional artificial marble bowls have problems such as water splashing due to water pressure when the faucet is suddenly opened, or water splashing during use, which can wet clothes.
なお陶器製のカウンタ付きボウルは製作後の歪
（とくに反り）が大きいので製作が困難なうえ、
高価であるという問題がある。 It should be noted that ceramic bowls with counters are difficult to manufacture as they are subject to large distortions (especially warping) after manufacture.
The problem is that it is expensive.

The undercut portion is heated above the deformation temperature of the thermoformed product. In this case, the thermoformed product tends to return to its pre-molding state, that is, to its plate shape, based on the so-called shape memory effect. Therefore, it is extremely easy to remove the bowl from the bowl after returning the deformation to a state where it can be removed. In that case, the removed thermoformed product can be reused by thermoforming it again.

のばあいはたとえばアンダーカツト部は熱成形品
と共に離型しうるように割型にしておく。 Further, when a male mold is used as the mold for thermoforming, the male mold A having a protrusion corresponding to the water return portion 4 fixed to the core portion 2 can be used. In that case, for example, the undercut portion is made into a split mold so that it can be released together with the thermoformed product.
前述の方法で一旦熱成形された樹脂板３は、以

向するようにセツトする。なおセツトする前に樹
脂板３の表面および雌型Ｂの内面にはそれぞれシ
リコン系などの離型剤を塗布しておく。 First, as shown in FIG. 1, the resin plate 3 is set so as to face the male die A. Before setting, the surface of the resin plate 3 and the inner surface of the female mold B are coated with a mold release agent such as silicone.
ついで樹脂板３と雌型Ｂの間に形成されるキヤ
ビテイ５内に注型用樹脂が注入される。 Next, a casting resin is injected into the cavity 5 formed between the resin plate 3 and the female mold B.
注型用樹脂としては従来公知の人工大理石用の
樹脂、すなわちアクリル樹脂、ポリエステル樹
脂、エポキシ樹脂などの液状樹脂に各種の無機質
粒子を充填材として含有させたものが用いられ
る。 As the casting resin, conventionally known resins for artificial marble, ie, liquid resins such as acrylic resins, polyester resins, and epoxy resins, containing various inorganic particles as fillers are used.
無機質粒子としては水酸化アルミニウム、水酸
化マグネシウム、炭酸カルシウム、珪砂などの粉
粒、あるいはそれらを含む天然岩の粉粒が多く用
いられる。 As the inorganic particles, powder particles of aluminum hydroxide, magnesium hydroxide, calcium carbonate, silica sand, etc., or powder particles of natural rocks containing these are often used.
なお注型用樹脂には適切な時期に重合開始剤な
どの触媒その他の添加剤が入れられる。 Note that a catalyst such as a polymerization initiator and other additives are added to the casting resin at an appropriate time.
雄型Ａのコア部２と樹脂板３とは水返し部４の

できる。しかし内圧による水返し部４の変形を少
なくするため、注型用樹脂が重合固化するときの
温度は50〜60℃以下にしておくのが好ましい。 The core part 2 and resin plate 3 of the male type A are separated from each other at the water return part 4, and a cavity 6 is formed there, but the projected area of the cavity with respect to the core part is small, and the resin temperature is not so high. Because it is not expensive (about 40-60
℃), and can sufficiently withstand pressure during casting. However, in order to reduce deformation of the water return part 4 due to internal pressure, the temperature at which the casting resin polymerizes and solidifies is preferably kept at 50 to 60°C or lower.
注型用樹脂が固まつたのち、まず雌型Ｂおよび
雄型Ａから製品Ｃと樹脂板３とを一緒に取り出

すると、アンダーカツトが小さくなるので、樹脂
板３の取りはずしが容易になる。 If the undercut is large and cannot be easily removed by elastic deformation alone, as shown in FIG.
When heated above the deformation temperature, the resin plate 3 tends to return to its thermoformed shape, that is, the flat plate shape.
By utilizing the so-called shape memory effect of such a thermoformed plate, the undercut becomes smaller, so that the resin plate 3 can be easily removed.
弾性変形のみを利用して取りはずした樹脂板３
はそのままつぎの形成作業に用いることができ
