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によりクランプする。
When casting an integral counter with a bowl or a molded product with an elevation made of artificial marble, the third
As shown in the figure, the lower mold 1 and the upper mold 2 are opposed to each other so as to form a molding space with a predetermined thickness, and a sealing material 3 is interposed between the peripheries of the lower mold 1 and the upper mold 2, and the clamp is Clamp with metal fittings 4.
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 through 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′をセツトする。 Further, as shown in FIG. 4, first a fixed amount of slurry 5 is supplied to the lower mold 1', and then the upper mold 2' is set on the lower mold 1' via the clamp fittings 4.
このとき、前もつて供給してあるスラリー５は
上型２′の下向き加圧力により押しげられて、成
型空間の全域に充満する。 At this time, the slurry 5 previously supplied is pushed down by the downward pressing force of the upper mold 2' and fills the entire molding space.

コストが高くなる問題があつた。
In the case of the former cast molding method, it is necessary to reduce the viscosity of the slurry in order to fill the entire molding space with 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、めのう調縞柄等の模様をつける場合が
あるが、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つた。 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, patterns such as agate-like stripes may be added, but with this method, the planar part is artificially worked. There was a problem that I couldn't solve.
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耐えるよう強度や剛性が必要
になり、特に樹脂型では、クランプ力により型に
疲労を来たし、型寿命が短かくなる問題があつ
た。 In the case of the latter cast molding method, the slurry is pushed upward by the downward pressure of the upper mold, so the mold must have strength and rigidity to withstand the pressure.Especially with resin molds, the clamping force causes the mold to This caused fatigue and shortened mold life.
また、スラリーの量も必要以上に多くなり、材
料ロスとなり、さらに前述と同様に縞柄等の模様
を平面的に作為的に作業することができない問題
があつた。 In addition, the amount of slurry is larger than necessary, resulting in material loss, and, as mentioned above, there is also the problem that it is not possible to create patterns such as stripes in a planar manner.

In order to solve the above problems, this invention fills a lower mold with slurry, then pushes it down to a predetermined position in the upper mold, first semi-cures or hardens the slurry at room temperature or by heating, and then The molding space on the vertical surface 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、ガイドピンによつて位置決め
し、また移動式の場合、下型に上型を載置し、ク
ランプ金具等でセツトする。 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 clamp fitting or the like.
上記下型１１に充填したスラリー１２は、常温
又は加熱によつて半硬化ないし硬化させる。即
ち、スラリー１２が上型１３及び下型１１の密閉
部を形成する。 The slurry 12 filled in the lower mold 11 is semi-cured or hardened at room temperature or by heating. That is, the slurry 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１１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 to the upper mold 13
A slurry 15 is filled into the molding space between the mold and the lower mold 11, and is hardened following the slurry 12.
ただし、スラリー１５は、上型１３と下型１１

が望ましい。 However, the slurry 15 is
A low viscosity is preferable so that it can easily flow down and fill the vertical surface.
なお、製品１６は、上型１３及び下型１１を取

As described above, according to the cast molding method of 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 fill the vertical molding space. Since the slurry is filled and subsequently cured, the slurry first filled in the lower mold is limited to the flat part. Therefore, the pressurizing force becomes extremely small, and the mold does not require rigidity, so a thin plate mold or a thin-walled mold can be used, and the weight and cost of the mold can be reduced.
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。 Furthermore, the slurry that is injected in advance can be used even if it has a high viscosity, resulting in cost reduction.
さらに、複雑な模様付けが可能になり、立面部
