車体生産用プレス型の製造方法、特にマスク、モデル粗
型材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of manufacturing a press mold for car body production, particularly a method of manufacturing a mask and a model rough shape material.
車体の生産工程ではプレス型等実物大のモデル（以下マ
スタモデルと称する）を製造し繰返し使用される。In the car body production process, a full-size model (hereinafter referred to as a master model) such as a press mold is manufactured and used repeatedly.

た後、エポキシ樹脂等硬化性のある樹脂液を流し込んで
パイプ枠４等で枠組みし、乾燥してエポキシ樹脂が固化
するとパイプ枠４も固定されて一体となり。As shown in Figure 6, the conventional method for manufacturing a master model is generally to use styrene foam, which is a foam material that is inexpensive and easy to work with, and cut the material to a specified length with a saw, and then inject epoxy resin 3.
A rough model 1 is manufactured by machining the part where a mold is made by pouring a resin liquid with equal hardening properties, and after pasting masking tape 2 on the surface of the rough model 1 to facilitate mold release, epoxy resin etc. A hardening resin liquid is poured in and framed with a pipe frame 4, etc., and when it dries and the epoxy resin solidifies, the pipe frame 4 is also fixed and integrated.
ラフモデル１から離型されてマスタモデル粗型材５とな

る。The rough model 1 is released from the mold to become a master model rough material 5. The surface 5a of this master model rough profile material 5 is cut by a cutter 6.
Then, the production of the master model rough material 5 is completed.

と発泡スチロールが溶は出し、ラフモデル１の製品形状
をくずす欠点があるため、発泡スチロールを溶かさない
材質のマスキングテープ２を使用する状況にあった。When the epoxy resin hardens, it is necessary to use a mold release agent to prevent the cured epoxy resin from sticking to the rough model 1, but the mold release materials that are commonly used are powder-like. For example, wax 1.
The products dissolved in step 1.1 are all dissolved in organic solvents, and when applied to rough model 1 made of styrofoam, the styrofoam will dissolve and the product shape of rough model 1 will be destroyed. I was in a situation where I was using masking tape 2 made of a different material.
ラフモデルにマスキングテープを貼って硬化性を有する
樹脂液を注入すると、樹脂が硬化する際に発生する硬化
熱でマスキングテープが溶融して粘着性を増し、ラフモ
デルと樹脂の硬化物とが接着して離型性が非常に悪くな
っていた。When masking tape is applied to a rough model and a curable resin liquid is injected, the curing heat generated when the resin hardens melts the masking tape and increases its stickiness, causing the rough model and the cured resin to adhere. The mold releasability was extremely poor.
更に離型後のマスタモデル粗型材の表面に半溶融したマ

低下をきたしている。Furthermore, the semi-molten masking tape sticks to the surface of the master model rough material after being released from the mold, and when machining the surface 5a of the master model rough material, it becomes entangled with the cutter 6, resulting in a decrease in workability.
本発明の目的は、上記問題点を消除した、離型性の良好

。An object of the present invention is to provide a method for manufacturing a master model rough mold material with good mold releasability, which eliminates the above-mentioned problems.

提供することにより達成される。[Means for Solving the Problems] The object of the present invention is to provide a master model rough mold material for manufacturing a press mold by pouring a curable resin liquid onto the mold surface of a rough model made of a foam material. This is achieved by providing a method for manufacturing a master model rough mold material, characterized in that a powder layer is formed on the mold surface of the rough model, and then a film layer is formed, and then a resin liquid is poured and hardened. Ru.

を容易にすると共に、粉体層上に形成された皮膜層は硬
さを有してラフモデルの型上の粉体層の剥離を防ぐので
、その上に流し込まれた樹脂を型表面に一様に分布させ
る。The powder layer formed on the surface of the rough model facilitates the introduction of air from the outside when removing the master model rough shape from the rough model, and the film layer formed on the powder layer has hardness. This prevents the powder layer on the rough model mold from peeling off, so the resin poured over it is evenly distributed over the mold surface.
本発明の実施例について図により説明する。第１図に示

スタモデル粗型材５とは、乾燥して粉体状になった砥粒
層８の層に空気が導入されやすいので容易に離型される
。Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a powder layer 8 is formed as a release layer between a rough model 1 made of styrene foam and a resin 3, that is, a cured product of epoxy resin.
That is, by forming an abrasive grain layer and a film layer 9 made of a water-soluble adhesive, the rough model 1 and the master model rough profile material 5 are made of abrasive powder that has dried and become powder, as shown in FIG. Since air is easily introduced into the grain layer 8, the mold can be easily released.

ると容易に水に溶けるか又は懸濁するので、この溶液を
第３図に示すように刷毛等でラフモデル１に塗布すると
均一な砥粒Ｍ８が形成される。Regarding the procedure for forming the release layer, a suitable powder for the powder layer 8 is abrasive grains. The abrasive grains are natural silica stones whose main component is aluminum silicate containing iron, and if the powder is mixed with water or hot water at a weight ratio of 2:1, it will dissolve easily in water or Since it is suspended, when this solution is applied to the rough model 1 with a brush or the like as shown in FIG. 3, uniform abrasive grains M8 are formed.
この砥粒層８を乾燥したままでエポキシ樹脂３を流し込

層８ではがれて丸まって形がくずれるので、本発明では
第５図に示すように砥粒層８上に、水溶性接着剤を適度

い。このエポキシ樹脂３にパイプ枠４等を取付け、乾燥
するとエポキシ樹脂３が固化するので、この固化物は砥
粒層８で容易に離型できてマスタモデル粗型材５が出来
上る。If the epoxy resin 3 is poured into the abrasive layer 8 while it is dry, the epoxy resin 3 will flow as shown in FIG. 4, peel off from the abrasive layer 8, curl up, and lose its shape. As shown in the figure, when a water-soluble adhesive is diluted with an appropriate amount of water and applied with a brush on the abrasive grain layer 8 and allowed to air dry, an extremely thin and hard film layer 9 is formed which retains its shape. Because of this, it does not lose its shape even when poured with epoxy resin. When the pipe frame 4 and the like are attached to this epoxy resin 3 and dried, the epoxy resin 3 solidifies, and this solidified product can be easily released from the mold by the abrasive grain layer 8, thereby completing the master model rough shape material 5.
離型後のマスタモデル粗型材５の表面に付着している物
質は水溶性接着剤の硬化した皮膜層と砥粒の粉体物であ
るから、マスタモデル粗型材５の表面を機械加工すると
きカッターに絡み付くこともなく容易に加工でき、従っ
て加工能率も向上する。The substances adhering to the surface of the master model rough material 5 after release are a hardened film layer of water-soluble adhesive and a powder of abrasive grains, so when machining the surface of the master model rough material 5, It can be easily machined without getting tangled with the cutter, thus improving machining efficiency.
発泡材からなるラフモデルの型表面上に形成された粉体

きその間に空気を導入し易くするので容易に離型できる
。粉体層上に形成された皮膜は硬さを有しそれ自体の形
状を保持するので、その上に樹脂を流し込んでも樹脂の
形をくずすことがない。The powder layer formed on the mold surface of the rough model made of foam material makes it easy to introduce air between the rough model material and the rough model material when the rough model material is released from the mold, so that the powder layer can be easily released from the mold. The film formed on the powder layer has hardness and maintains its shape, so even if resin is poured onto it, the resin will not lose its shape.
離型後のマスタモデル粗型材に付着している硬化した皮

すく、マスタモデル粗型材からマスタモデルを成形する
際にもマスタモデル粗型材の機械加工を阻害する物質で
はないので機械加工を精密且つ能率よく行うことができ
る。The hardened film layer and powder that adhere to the master model rough material after release from the mold are easily dissolved in water, so they can be easily removed by washing with water, etc., and when molding the master model from the master model rough material. Since it is not a substance that inhibits machining of the rough model material, machining can be performed precisely and efficiently.
また、付言すれば本発明による粉体層と皮膜層とからな

。Additionally, the number of man-hours required to produce a release layer consisting of a powder layer and a film layer according to the present invention is approximately one-sixth that of the conventional masking tape method, resulting in a significant reduction in man-hours.
