この発明は、人造大理石や注型レジンコンクリートの注
型成形方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cast molding method for artificial marble or cast resin concrete.
人造大理石でボールのついた一体形カウンターや立面を
有する成型品を注型成形する場合、第３図で示したよう
に所定肉厚の成形空間を形成するよう下型１に上型２を
対向させると共に、上記下型１と上型２との周縁間にシ
ール材３を介在させ、そしてクランプ金具４によシフラ
ンデする。When casting an integral counter with a ball or a molded product with an elevation made of artificial marble, the upper mold 2 is placed on the lower mold 1 to form a molding space with a predetermined wall thickness, as shown in Figure 3. While facing each other, a sealing material 3 is interposed between the peripheral edges of the lower mold 1 and the upper mold 2, and the clamp fittings 4 are used to clamp the molds.
次いで、上型２の注入口５から成型空間にスラリー５を
充填する。Next, the slurry 5 is filled into the molding space from the injection port 5 of the upper mold 2.
また、第４図で示したようにまず下型１′に定量のスラ
リー５を供給したのち、上記下型１′にクランプ金具４
を介し上型２をセットする。In addition, as shown in FIG. 4, after first supplying a certain amount of slurry 5 to the lower mold 1', the clamp fitting 4 is placed on the lower mold 1'.
Set the upper mold 2 through the .
このとき、前もって供給しであるスラリー５は上型２゛
の下向き加圧力により押し上げられて、成型空間の全域
に充満する。At this time, the slurry 5 supplied in advance is pushed up by the downward pressing force of the upper mold 2 and fills the entire molding space.
前者の注型成形方法の場合、成形空間にくまなくスラリ
ーを充填させるためて、スラリーの粘度を低粘度化する
必要があり、しかも全体積にわたシ低粘度化されたスラ
リーであることが必要であるので、スラリーの樹脂比率
が高くなり、原材料コストが高くなる問題があった。In the case of the former cast molding method, in order to fill the entire molding space with slurry, it is necessary to reduce the viscosity of the slurry, and the slurry needs to have a low viscosity throughout the entire volume. Therefore, there was a problem that the resin ratio of the slurry was high and the cost of raw materials was high.
また、成形物のスケールが大きい場合、注入口が狭いた
め注入時間が長くなり、さらに、人造大理石では、めの
う調縞柄等の膜様をつける場合がおるが、この方法では
平面部に作為的に作業することができない問題があった
。In addition, if the scale of the molded product is large, the injection time will be longer because the injection port is narrow.Furthermore, with artificial marble, a film pattern such as an agate-like striped pattern may be added, but this method artificially creates a pattern on the flat surface. There was a problem that made it impossible to work.
後者の注型成形方法の場合、上型の下向き加圧力により
スラリーを上向き方向き方向に押し上げるために型が加
圧に酎えるよう強度や剛性が必要になシ、特に樹脂型で
は、フラング力によυ型に疲労を来たし、型寿命が短か
くなる問題があった。In the case of the latter cast molding method, the slurry is pushed up in the upward direction by the downward pressure of the upper mold, so the mold needs strength and rigidity to handle the pressure. This caused fatigue in the υ mold and shortened the life of the mold.
また、スラリーの量も必要以上に多くなシ、材料ロスと
なシ、さらに前述と同様に編柄等の膜様を平面的に作為
的に作業することができない問題があった。Further, there are problems in that the amount of slurry is larger than necessary, material loss occurs, and, as mentioned above, it is not possible to intentionally create a film pattern such as a knitted pattern in a two-dimensional manner.
上記の問題点を解決するために、この発明は下型にスラ
リーを充填させたのち、上型の所定の位置まで押し下げ
て上記のスラリーを先に常温或は加熱によシ半硬化ない
し硬化させ、次いで立面の成型空間にスラリーを充填し
て追随硬化させるようにしたものである。In order to solve the above problems, this invention fills the lower mold with slurry, then pushes it down to a predetermined position in the upper mold, and first semi-cures or hardens the slurry at room temperature or by heating. Then, the vertical molding space is filled with slurry and cured accordingly.
以下、この発明に係る注型成形方法を添付図面に基づい
て説明する。Hereinafter, the cast molding method according to the present invention will be explained based on the accompanying drawings.
まず、第１図で示したように下型１１にスラリー１２を
充填したのち、上型１３を所定の位置まで降下させる。First, as shown in FIG. 1, the lower mold 11 is filled with slurry 12, and then the upper mold 13 is lowered to a predetermined position.
上記上型１３は、定置式の場合、シリンダ等を用いて降
下させ、ガイドピンによって位置決めし、また移動式の
場合、下型に上型を載置し、クヲンデ金具等でセットす
る。In the case of a stationary type, the upper mold 13 is lowered using a cylinder or the like and positioned by guide pins, and in the case of a movable type, the upper mold is placed on the lower mold and set with a bracket or the like.
上記下型１１に充填したスラリー１２は、常温又は加熱
によって半硬化ないし硬化させる。The slurry 12 filled in the lower mold 11 is semi-cured or hardened at room temperature or by heating.
即ち、スラＩＪ −１２が上型１３及び下型１１の密閉
部を形成する。That is, the slurry IJ-12 forms a sealed portion of the upper mold 13 and the lower mold 11.
次に、上型１３の注入口１４から上記上型１３と下型１
１との成型空間にスラリー１５を充填し、スラリー１２
に追随して硬化させる。Next, from the injection port 14 of the upper mold 13, the upper mold 13 and the lower mold 1 are
The molding space between slurry 12 and slurry 12 is filled with slurry 15.
to harden.
ただし、スラリー１５は、上型１３と下型１１との立面
部に容易に流下充填するよう低粘度の方が望ましい。However, it is preferable that the slurry 15 has a low viscosity so that the slurry 15 can easily flow down and fill the vertical surfaces of the upper mold 13 and the lower mold 11.
なお、製品１６は、上型１３及び下型１１を取υ外して
得る。Note that the product 16 is obtained by removing the upper mold 13 and the lower mold 11.
また、製品１６は、図示の場合、ボールの付いたカウン
ターを示したが、その池の形状、即ちスラリー１５の注
入空間が上方に突出してスラリー１２が下方に流下しな
いものであればよい。Further, although the product 16 is shown as a counter with a ball in the illustrated case, it may be any shape as long as the pond shape, that is, the injection space for the slurry 15 protrudes upward and the slurry 12 does not flow downward.
以上のように、この発明に係る注型成形方法によれば、

量化やコストダウンをはかることができる。As described above, according to the cast molding method according to the present invention,
After filling the lower mold with slurry, the upper mold is pushed down to first semi-cure or harden the slurry, and then the vertical molding space is filled with slurry and cured accordingly, so the slurry filled in the lower mold first is limited to flat areas. Therefore, the pressurizing force becomes extremely small, and the mold does not require rigidity, making it possible to use a thin-walled plate or a thin-walled mold, thereby making it possible to reduce the weight and cost of the mold.
また、先行注入するスラリーは、高粘度でも使用するこ
とができるので、コストダウンになる７
さらに、複雑な模様付けが可能になシ、立面部の多少高
低に対応することができる。In addition, the slurry that is injected in advance can be used even if it has a high viscosity, resulting in cost reduction.7 Furthermore, it is possible to create complex patterns, and it is possible to adapt to the height of the elevation.
