【発明の詳細な説明】 技術分野 本発明は、熱可塑性材料の製品、特に試作部分（ｐｒｏｔｏｔｙｐｅ ｐｉｅｃ ｅｓ）を成形する方法に関する。[Detailed description of the invention] Technical field The present invention relates to products of thermoplastic materials, especially prototype parts. es).
背景技術 強化プラスチック材料シートのような熱可塑性材料は、最初この材料を軟化温度 に加熱し、次いで型（ｍｏｕｌｄ）へ移して押圧し凝固（ｓｅｔ）させることに より製品に成形される。型は通常機械加工または鋳造された金属型である。Background technology Thermoplastic materials, such as sheets of reinforced plastic material, are initially heated to a softening temperature of this material. The mixture is heated to , then transferred to a mold and pressed to set. molded into products. The mold is usually a machined or cast metal mold.
従って、試作部品の製作は特に困難かつ高価であり時間を要するものであった。Therefore, the production of prototype parts has been particularly difficult, expensive, and time consuming.
発明の開示 本発明の目的は、熱可塑性材料で成形される製品の製造、特に試作部品の製作が 従来より速くかつ高価でない方法を提供することにある。Disclosure of invention The purpose of the invention is to manufacture products molded from thermoplastic materials, in particular to manufacture prototype parts. The objective is to provide a method that is faster and less expensive than conventional methods.
本発明の方法によれば、熱可塑性材料のシートは加熱されてから塁に移され、こ の梨に対して押圧により成形される。本発明の特徴は、この型か裏打ち材料（ｂ ａｃｋｉｎｇＩｌｌａｔｅｒｉａｌ）によって平坦な型台に対して裏打ちされた モデル（ｂａｃｋｅｄ ｍｏｄｅｌ）であることである。According to the method of the invention, a sheet of thermoplastic material is heated and then transferred to the base; It is formed by pressing against the pear. A feature of the present invention is that this mold or backing material (b backed against a flat mold base by ackingIllatterial) It is a backed model.
本発明が採用されれば従来のような型を製作する必要はなくなる。所望の形状の モデルが型として使用出来る。If the present invention is adopted, there will be no need to manufacture conventional molds. of desired shape The model can be used as a mold.
モデルの下面、すなわち型台に対向する面が平面である必要はない。モデルは、 例えば上下逆にした皿の形状でもよく、金属の薄板で作られていてもよい。本発 明によってモデルは、型台上に置かれる前に、例えば発泡ポリウレタンを充填さ れて平面状の下面を育することになる。The lower surface of the model, that is, the surface facing the mold table, does not need to be flat. The model is For example, it may be in the shape of an upside-down dish, or it may be made of a thin metal plate. Main departure Depending on the model, the model may be filled with e.g. foamed polyurethane before being placed on the mold table. This results in the growth of a flat lower surface.
表面を平面に形成するのか容易な材料が裏打ち材料として使用するのに適してい る。この種類の材料は、例えばポリウレタンのような発泡性の凝固可能な（ｓｅ ｔｔａｂｌｅ）物質、または石膏のような成形可能な（ｃａｓｔｉｎｇ）材料で ある。モデルを型台上に置く前に、裏打ち材料かモデルの下面を型台に対して置 かれる平坦な表面を形成するように成形される。Materials that can be easily formed into a flat surface are suitable for use as backing materials. Ru. Materials of this type are e.g. a ttatable substance, or a casting material such as plaster be. Before placing the model on the mold table, place the backing material or the underside of the model against the mold table. molded to form a flat surface.
本発明の方法によれば、既知の方法により製作された製品のような対応する特性 、例えば外観、絶縁能力、剛性などをもつ試作部分を迅速かつ安価に製作するこ とが可能である。本方法は大きい形状変化範囲のモデルを使用することを可能に している。種々の形状のモデルに対して同じ平面型台が使用出来るので、工具の 費用は高くはならない。モデルは、例えば木、合板、金属の薄板、またはポリエ ステルのシートなどのような種々の材料により作られ得る。高温の熱可塑性シー トにより変形されないことかモデル材料の必要条件である。According to the method of the invention, corresponding properties like products made by known methods For example, it is possible to quickly and inexpensively produce prototype parts with good appearance, insulation ability, rigidity, etc. is possible. This method allows the use of models with a large shape variation range. are doing. The same flat table can be used for models of various shapes, making it easier to use tools. The cost will not be high. The model can be made of e.g. wood, plywood, sheet metal or polyester. It can be made of a variety of materials, such as sheets of stell, etc. high temperature thermoplastic sheet It is a necessary condition for the model material that it is not deformed by the material.
図面の簡単な説明 本発明はさらに例として付図を参照して説明され、付図は本発明の方法による試 作部品の製作を示す断面略図である。Brief description of the drawing The invention will be further explained by way of example with reference to the accompanying drawings, which illustrate experiments by the method of the invention. FIG. 3 is a schematic cross-sectional view showing the production of the workpiece.
本発明を実施する最良の形態 図においてモデル２が裏打ち材料ｌにより支持され、平坦な頂面をもつ型台６上 に置かれる。炉中て加熱された熱可塑性材料の完全に柔軟で曲げ易いシート３が 型（ｌおよび２）へ移される。圧力値（ｂｅｌｌ）５の弾性膜４が当てられ、熱 可塑性材料を圧力鑵内の圧力により型に対して緊密に押圧している。同時に空気 が成形されるシートの領域から通路７を通り排出される。シート３が冷却によっ て凝固されると、型から外される。BEST MODE FOR CARRYING OUT THE INVENTION In the figure, a model 2 is supported by a backing material l and placed on a mold table 6 with a flat top surface. placed in A completely flexible and pliable sheet 3 of thermoplastic material is heated in a furnace. Transferred to molds (l and 2). An elastic membrane 4 with a pressure value (bell) of 5 is applied, and heat is applied. The plastic material is pressed tightly against the mold by pressure within the pressure lock. air at the same time is discharged through a passage 7 from the region of the sheet to be formed. Sheet 3 is cooled Once solidified, it is removed from the mold.
０．１ＭＰａ以下の圧力が大抵の場合押圧するのに適当である。しかし特に裏打 ち材料の密度が増大すると、より高い圧力が使用可能である。Pressures below 0.1 MPa are suitable for pressing in most cases. But especially the back As the density of the material increases, higher pressures can be used.
工業的適用性 本発明の方法は、繊維成分とプラスチック成分とが一緒にされた、多孔性シート 状の繊維強化された、圧縮されない粒状（ｐａｒｔｉＣｌ−ｆｏｒｍ）のプラス チック材料の試作部品を成形するのに最もよく適用され得る。勿論本発明によっ て、例えば織物により被覆された強化プラスチック半製品、または種々の繊維含 有量の層を積層して構成された半製品を成形することもまた可能である。industrial applicability The method of the present invention comprises a porous sheet in which a fiber component and a plastic component are combined. fiber-reinforced, incompressible granular (partiCl-form) plus It can be best applied for molding prototype parts of tick materials. Of course, the present invention For example, reinforced plastic semi-finished products covered with textiles or various fiber-containing It is also possible to form semi-finished products made up of a number of stacked layers.
