【発明の詳細な説明】
本発明は型枠内で注型硬化した水硬性塑造材料を効率よ
く脱型分離する方法に関するものである，一般に水硬性
塑造材料は硬化後も含水状態では未だ充分な強度を発現
しておらず、このような強度の弱い状態で、しかも繊細
な凹凸模様や垂直に近い角度のシャープな凹凸模様を形
成した型枠から、破損することなく、効率よく脱型分離
することは極めてむつかしいことであった。[Detailed Description of the Invention] The present invention relates to a method for efficiently demolding and separating a hydraulic plastic material that has been cast and hardened in a mold. Efficiently removes and separates molds without damage, from formwork that has not developed any strength and has a delicate uneven pattern or a sharp uneven pattern with a nearly vertical angle. This was extremely difficult.
この種の脱型分離方法として、本出願人は、先に、特公
昭５２−４２８２号公報に示されているように、泥漿物
を型枠に注型硬化後、塑造材料の裏面を上側にした状態
で連続的に吸着搬送しながら、下側にある型枠を連続的
に離脱させる方法について提案した。As a demolding separation method of this type, the present applicant previously proposed a method in which, after pouring and hardening a slurry into a mold, the back surface of the plastic material was turned upward, as shown in Japanese Patent Publication No. 52-4282. We proposed a method to continuously remove the formwork at the bottom while continuously suctioning and transporting the mold in a state that is
しかし、この方法では、脱型後、塑造材料の化粧面が下
側となり、後工程への搬送、規定寸法に切断すること、
更には化粧面を上側にして乾燥するための反転といった
操作で屡々化粧面を傷付けたり、破損したりする欠点が
あった。However, in this method, after demolding, the decorative surface of the plastic material is on the lower side, and it is difficult to transport it to the subsequent process, cut it to specified dimensions,
Furthermore, there is a drawback that the decorative surface is often scratched or damaged by operations such as inversion for drying with the decorative surface facing up.
本発明は、この欠点を解決することを目的としてなされ
たものであって、その要旨とする所は、可撓性物質製の
型枠内で注型硬化させた水硬性塑造材料を該型枠と共に
反転し、下側となった該塑造材料の面を吸引力によって
固定してから、つぎに上記型枠をその両端から凹形状に
屈曲させつつ徐々に上方に引き上げることにある。The present invention was made with the aim of solving this drawback, and the gist of the present invention is to use a hydraulic plastic material that has been cast and hardened within a mold made of a flexible material. The molding material is turned over at the same time, and the lower surface of the plastic material is fixed by suction force, and then the mold is gradually pulled upward while being bent into a concave shape from both ends.
本発明の方法を実施するに好適な装置を示した図示の実
施例により詳述すると、つぎのとおりである。The method of the present invention will now be described in more detail with reference to illustrative embodiments showing apparatus suitable for carrying out the method of the invention.
本発明で使用される型枠１は、シリコン樹脂、ポリウレ
タン樹脂等のエラストマーといった可撓性物質でもって
、所望する凹凸模様を形成した母型盤面部分１ａも厚み
規正用枠部分１ｂも一体に成型されてなるものである。The formwork 1 used in the present invention is made of a flexible material such as an elastomer such as silicone resin or polyurethane resin, and the mother plate surface portion 1a, which has a desired uneven pattern, and the thickness regulating frame portion 1b are integrally molded. It is something that has been done.
該型枠１内で注型硬化させる水硬性塑造材料２としては
、補強用の各種短繊維を適宜量混和した石膏泥漿物が挙
げられるが、これに限られないことは勿論である。The hydraulic plastic material 2 to be cast and hardened within the mold 1 may include, but is not limited to, gypsum slurry mixed with an appropriate amount of various reinforcing short fibers.
型枠１内で注型硬化させた水硬性塑造材料２を型枠１と
共に反転する機構としては、前記特公昭５２−４２８２
号公報に詳記されており、本発明の場合も同様な吸着反
転機を使用して反転させることができる。A mechanism for inverting the hydraulic plastic material 2 cast and hardened in the formwork 1 together with the formwork 1 is disclosed in the above-mentioned Japanese Patent Publication No. 52-4282.
It is described in detail in the above publication, and in the case of the present invention, a similar adsorption/inversion machine can be used for inversion.
反転により型枠１が上側に、塑造材料２が下側となる。By reversing, the formwork 1 is on the upper side and the plastic material 2 is on the lower side.
下側となった塑造材料２の面を吸引力によって固定する
には、第１図に示すように、下部はターボファン等の排
気装置５と連結した吸引函３の通気可能な多孔上面４に
直接載置するとか、或いは図示するを省略したが、吸引
函３の上面と接して走行する多孔無端帯で吸引函３上部
に搬送することによって達成される。In order to fix the lower surface of the plastic material 2 by suction force, as shown in FIG. This can be achieved by placing it directly or, although not shown, by conveying it to the upper part of the suction box 3 using a porous endless belt that runs in contact with the top surface of the suction box 3.
つぎに上記型枠１をその両端から凹形状に屈曲させつつ
徐々に上方に引き上げるのであるが、それにはつぎのよ
うな型枠分離機６によって行なうことができる。Next, the formwork 1 is bent into a concave shape from both ends and gradually pulled upwards, which can be done by a formwork separator 6 as described below.

２，１２を回動自在に枢着する。That is, a threaded rod 10 with opposite left and right threads driven by a motor 9 is rotatably held on a support member 8 attached to the rod end of the cylinder 7 and can be moved up and down.
The hook arms 1 are attached to the sliders 11 and 11 screwed together on the left and right sides of the
2 and 12 are pivotably attached.

離され、やがて全体に及んで完全に脱型分離される。Now, suppose that after operating the cylinder 7 to bring it from the raised position to the lowered position shown in FIG. As can be seen from FIGS. 2 and 3, especially from FIG. 3, the mold 1 is bent into a concave shape from both ends and peeled off, and then the entire mold is completely removed and separated.
第４図はモーター９を逆転することによって脱型分離し
た型枠１を真直ぐにした状態を示す。FIG. 4 shows a state in which the demolded and separated formwork 1 is straightened by rotating the motor 9 in the reverse direction.

無理な力をかけないで脱型でき、該個所に欠けを生じさ
せることがない点で甚だ優れている。As described above, according to the method of the present invention, the lower surface of the plastic material is firmly fixed by suction force, and the flexibility of the mold is used to bend the mold into a concave shape from both ends. Since it is gradually pulled upward and peeled off, it can be removed even in places where the cast-hardened plastic material adheres like an anchor along the uneven surface of the formwork.
It is extremely superior in that it can be removed from the mold without applying excessive force and does not cause chipping at the location.
