その雄型の新規な構造に関する。[Detailed description of the invention] [Field of industrial application] The present invention is a vacuum-pressure air system that gives a desired shape to a sheet material using a male mold equipped with an assist plug and a female mold (mold) equipped with a vacuum means. This invention relates to molding, and in particular to a novel structure of its male mold.

To explain the structure of the conventional male mold used in the above-mentioned type of molding method, Figs.
As shown in the figure, a hollow assist plug 2 having a desired external shape is fixed onto a frame 1 using epoxy resin. A large number of through holes 3 are distributed and provided on the surface of the assist plug 2, and each hole 3 is
It communicates with a common metal pipe 5 through a synthetic resin pipe 4. One end of this metal pipe 5 communicates with the outside through a cold air supply hole 6 provided in the bottom wall of the frame 1. Further, a compressed air opening 7 for supplying or discharging compressed air to the hollow portion of the assist plug 2 is provided in the bottom wall of the frame body 1, and a compressed air opening 7 for supplying or discharging compressed air to the hollow portion of the assist plug 2 is provided at the periphery of the assist plug 2. A blowout opening 8 is provided for blowing out the air.

保持し、これを適当な加熱手段によつて加熱して
可塑化しておく（第５図ａ）。 An outline of the vacuum-pressure forming method using such a male mold will be described based on FIG. 5. Male type 1 with the above configuration
A sheet material 13 to be molded is placed between a female mold 11 having a recess shaped approximately complementary to that of the assist plug 2 and a vacuum box 12 for applying a vacuum to the recess. It is held by a clamp 14 and heated by a suitable heating means to plasticize it (FIG. 5a).
次いで、両型１０，１１を合体させ、同時に雄

ラグ２の表面形状に沿つて押し上げる（第５図
ｂ）。 Next, both molds 10 and 11 are combined, and at the same time, with the cold air supply hole of the male mold 10 closed, compressed air is blown from the compressed air opening 7 to push up the sheet material 13 along the surface shape of the assist plug 2 (Fig. 5). b).

されている（第５図ｃ）。 While maintaining this state, the vacuum box of the female mold 11 is operated to bring the sheet material 13 into close contact with the wall surface of the recess of the female mold. Incidentally, the dimensional relationship is such that when the two molds are combined, a predetermined gap is created between the surface of the male assist plug 2 and the wall surface of the female recess (FIG. 5c).

なお、図において矢印は圧空の流れを示す。 Next, cooling air is introduced into the molding space through the cold air supply hole 6 to cool the assist plug 2 and the sheet material 13, and the air in the system is exhausted through the compressed air opening 7 (FIG. 5d). Molded sheet material 13
Once it has cooled down enough, open the mold and take it out.
Note that in the figure, arrows indicate the flow of compressed air.

隔が保たれるように作製される必要がある。又、
全工程を通じて雌型の方はその内部にはりめぐら
された冷却パイプを通じて冷媒を流すことによつ
て常に冷却されている。 As is clear from the above explanation, the shape of the molded product is determined by the shape of the recess in the female mold (mold), and the assist plug does not have to be manufactured as precisely as the female mold. It is necessary to manufacture the assist plug so that when the two molds are combined, a constant distance is maintained between the entire surface of the assist plug and the recess of the female mold. or,
Throughout the entire process, the female mold is constantly cooled by flowing refrigerant through cooling pipes placed inside it.
上述の従来型の雄型のアシストプラグは、エポ

The conventional male-type assist plug mentioned above is a hollow body made of epoxy resin, and it is difficult to install strong cooling means like in the case of the female type, so it is necessary to perform continuous molding work. In some cases, heat builds up and reaches very high temperatures, making it difficult to cool the molded product quickly. Furthermore, due to this heat accumulation, the sheet material tends to stick to the assist plug during the forming operation, and smooth stretching during forming is inhibited, resulting in variations in the thickness of the product.
又、アシストプラグの全表面を雌型の凹部から
所定の距離例えば20mmの間隔を保つように作製す
る必要があるため、多くの製造工数を要しコスト
高となる欠点がある。 Furthermore, since it is necessary to manufacture the entire surface of the assist plug so as to maintain a predetermined distance, for example, 20 mm, from the recess of the female mold, there is a drawback that a large number of manufacturing steps are required and the cost is high.
本考案は上に述べた従来技術の欠点を解決する
ことを目的とし、冷却が容易でしかも製作が簡単
なアシストプラグを提供することを目的とする。
The present invention aims to solve the above-mentioned drawbacks of the prior art, and aims to provide an assist plug that is easy to cool and easy to manufacture.
この目的は、熱伝導性の良好な棒状又は平板状
材料を用いて、格子状に成形表面を形成した真空
圧空成形用アシストプラグによつて達成すること
ができる。 This objective can be achieved by an assist plug for vacuum-pressure molding in which a rod-shaped or plate-shaped material with good thermal conductivity is used and a molding surface is formed in a lattice shape.
この熱伝導性の良好な材料としては金属製のパ
イプやストリツプが望ましい。 A metal pipe or strip is preferable as the material with good thermal conductivity.
又、このアシストプラグの外形を構成するパイ

とが望ましい。 Further, it is desirable that the surface of the pipe constituting the outer shape of the assist plug is subjected to a surface treatment using a resin to control the sliding state of the sheet material to be molded.
図面に示す好適実施例に基づいて本考案を更に
詳細に説明する。
The present invention will be explained in more detail on the basis of preferred embodiments shown in the drawings.

グ２２が作られている。 FIG. 1 is a perspective view of a male mold equipped with an assist plug of the present invention. On a frame 21, rod-shaped materials 20 with good thermal conductivity such as steel pipes are combined in a lattice pattern, and the female mold ( The assist plug 22 is made to have an outer shape corresponding to the shape of a molding recess (not shown).
型枠２１には前述の第３，４図に示す従来型の
アシストプラグ２の場合と同様に、スチールパイ
プ製のアシストプラグ２２の中空内部に対する圧
空開口２７と冷風供給孔２６が設けられている。
又、従来型の装置に設けられていた冷却風供給用
のパイプ４，５は撤去されている。 The formwork 21 is provided with a pressurized air opening 27 and a cold air supply hole 26 for the hollow interior of the steel pipe assist plug 22, as in the case of the conventional assist plug 2 shown in FIGS. 3 and 4 described above. .
Furthermore, the pipes 4 and 5 for supplying cooling air, which were provided in the conventional device, have been removed.

ーテイングすれば、シート材料の滑りがよくなつ
て成形の際によく延伸されるようになり、これに
よつて成形品の肉厚を任意に制御することが可能
となる。 The surface of the steel pipe constituting this assist plug 22 is subjected to surface treatment at appropriate locations 29 as required. That is, if the sheet material is coated with a resin having a large coefficient of friction, such as a heat-resistant urethane resin, the elongation of the sheet material in the portions that come into contact with this during molding will be restricted.
On the other hand, if the sheet material is coated with a material with excellent lubricity, such as a fluororesin, the sheet material will slip better and be stretched better during molding, thereby allowing the thickness of the molded product to be controlled as desired. It becomes possible to do so.
本考案の雄型の使用法は、前述の従来型の場合

隙間２３を通つて均等にシート材料を持ち上げる
のにも使用している。 The method of using the male type of the present invention is substantially the same as that of the conventional type described above, so detailed steps will be omitted.
I will only mention the different points. The gap 23 between the steel pipe grids is filled with a conventional assist plug 2.
However, whereas the through hole 3 was provided only for the purpose of supplying cooling air from the cold air supply hole 6 into the system, in the present invention, the cooling air is supplied from the compressed air opening 27 into the system. The compressed air is also used to evenly lift the sheet material through the gaps 23 in these grids.
成形に際し、シート材料はアシストプラグ２２

れ、所望の板厚の製品を得ることが可能となる。 During molding, the sheet material is used as an assist plug 22.
The steel pipe is deformed when it comes into contact with the surface of the steel pipe, but the stretching state is controlled by the presence of resin-treated areas 29 on the surface of the steel pipe, making it possible to obtain a product with the desired thickness. becomes.
なお、アシストプラグの製作に使用される金属
としては、前述の例に上げたスチールの他にアル
ミニウムやステンレス等の好適に利用可能であ
る。 Note that, in addition to the steel mentioned above, aluminum, stainless steel, and the like can be suitably used as the metal used for manufacturing the assist plug.
以上詳述した通り、本考案のパイプ製アシスト

てすみコストが低減できる。
As detailed above, the male type equipped with the pipe-made assist plug of the present invention has fewer attached structures than the conventional assist plug made of a hollow body made of epoxy resin, and also has materials such as pipes along the outer shape. Since the desired shape can be created by bending, the number of manufacturing steps can be reduced and costs can be reduced.
又、アシストプラグを構成する材料として熱伝
導性が良好なものを選んでいるので、冷却が迅速
に行われ、たとえ連続的に成形を繰り返したとし
ても熱が蓄積して高温になることが避けられる。 In addition, since we have selected a material that has good thermal conductivity for the assist plug, cooling occurs quickly, and even if molding is repeated continuously, heat will not accumulate and reach high temperatures. It will be done.
更に、パイプの表面の適宜個所にシート材料の
延伸を制御できる表面処理を施したので、所望の
板厚の製品を効率よく得ることができる。 Furthermore, since the surface of the pipe is subjected to a surface treatment that can control the stretching of the sheet material, it is possible to efficiently obtain a product with a desired thickness.
