Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は、スラッシュ成形に用いられる金型装置の改良
に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an improvement of a mold device used for slush molding.
（従来の技術） 従来より、この種の金型装置として、例えば実開昭60-1
30015号公報に開示されているように、シェル状の金型
の裏面に熱媒体としてのオイル等の流体を通す温度調節
用配管を設けたものが一般によく知られている。(Prior Art) Conventionally, as a mold apparatus of this type, for example, the actual open sho 60-1
As disclosed in Japanese Patent No. 30015, it is generally well known that a shell-shaped mold is provided with a temperature adjusting pipe through which a fluid such as oil as a heat medium is passed on the back surface.
（考案が解決しようとする課題） ところが、上記の従来のものでは、温度調節用配管は金
型裏面にハンダ付けやロウ付けによって取り付けられて
いることから、一旦取り付けるとその後の位置変更が非
常に困難であり、したがって、その取付け作業は極めて
慎重に行われているのが現状である。しかし、温度調節
用配管を如何に慎重に取り付けたとしても、実際に流体
を流してみると、型温を金型全体に亘って均一に設定す
ることができない場合も起こり得、この場合には熱効率
が悪くなって成形性が低下することとなる。(Problems to be solved by the invention) However, in the above-mentioned conventional one, since the temperature adjusting pipe is attached to the back surface of the mold by soldering or brazing, once it is attached, the position change after that is extremely difficult. It is difficult, and therefore, the mounting work is currently extremely careful. However, no matter how carefully the temperature control pipes are attached, it may happen that the mold temperature cannot be set uniformly over the entire mold when actually flowing the fluid. The thermal efficiency is deteriorated and the formability is lowered.
また、温度調節用配管を金型に取り付けるハンダ等は、
型温度の上昇に伴う温度差と、熱膨脹率の差により外れ
ることがあり、この場合には、上記温度調節用配管が金
型から外れたり大きく位置ずれして使用に供し得なくな
り、耐久性が低下するという問題もある。Also, solder etc. that attach the temperature control pipe to the mold,
It may come off due to the temperature difference due to the rise of the mold temperature and the difference in the coefficient of thermal expansion, and in this case, the temperature control pipe may come off the mold or be misaligned so that it cannot be used and durability is improved. There is also the problem of lowering.
さらには、上述の如く温度調節用配管を一旦金型に取り
付けると、作業性等を考慮として余程の不都合がない限
り取り外すことはなく、したがって、金型毎に専用の温
度調節用配管を準備する必要があって制作費が高騰する
という問題もあった。Furthermore, once the temperature control pipes have been attached to the mold as described above, they will not be removed unless there is a great deal of inconvenience in consideration of workability, etc. Therefore, prepare a dedicated temperature control pipe for each mold. There was also the problem that production costs would rise because of the need to do so.
本考案はかかる諸点に鑑みてなされたものであり、その
目的とするところは、上述の如き不都合が生ずる温度調
節用配管に替わて適切な温度調節手段を講ずることによ

ンダ付け等の作業をなくして耐久性の向上を図り、さら
には制作費の低減化をも図らんとすることにある。The present invention has been made in view of the above points, and an object of the present invention is to improve thermal efficiency by forming an appropriate temperature adjusting means in place of the temperature adjusting pipe that causes the inconvenience described above. It is intended to improve the durability, improve the durability by eliminating the work such as soldering, and further reduce the production cost.
（課題を解決するための手段） 上記の目的を達成するため、本考案の解決手段は、シェ
ル状の金型の裏面を型温を調節する熱媒体の出入口を有
するカバー材で覆い、かつ上記熱媒体の流れ方向を可変
調整する複数の整流手段を、上記カバー材と上記金型と
の間に形成される閉空間に臨むようにカバー材に設ける
ようにする。(Means for Solving the Problem) In order to achieve the above object, the solution means of the present invention is to cover the back surface of a shell-shaped mold with a cover material having a heat medium inlet / outlet for adjusting the mold temperature, and A plurality of rectifying means for variably adjusting the flow direction of the heat medium is provided on the cover member so as to face the closed space formed between the cover member and the mold.
（作用） 上記の構成により、本考案では、カバー材の入口から該
カバー材と金型との間に形成される閉空間に流入された
熱媒体は、上記カバー材に上記閉空間に臨むように設け
られた複数の整流手段により流れ方向が適正に調整さ
れ、出口から出ていく。(Operation) According to the present invention, according to the present invention, the heat medium flowing from the inlet of the cover material into the closed space formed between the cover material and the mold faces the cover material in the closed space. The flow direction is properly adjusted by a plurality of rectifying means provided in the outlet, and the flow exits from the outlet.
このことから、実際に熱媒体を流してみて、型温が金型
全体に亘って均一に設定されていない場合であっても、
上記各整流手段を可変調整することで型温が確実かつ容
易に金型全体に亘って均一に設定され、よって熱効率が
良くなって成形性の向上が図られることとなる。From this, when actually flowing the heat medium, even if the mold temperature is not set uniformly over the entire mold,
By variably adjusting each of the rectifying means, the mold temperature can be reliably and easily set uniformly over the entire mold, so that the thermal efficiency is improved and the moldability is improved.
また、温度調節用配管を用いる必要がなくなり、よって
該温度調節用配管が熱媒体の熱作用による温度差によっ
てハンダが金型から外れ大きく位置ずれして使用に供し
得なくなることがなくなって、耐久性の向上が図られる
こととなる。Further, it is not necessary to use the temperature control pipe, and therefore the temperature control pipe is prevented from being unusably used because the solder is largely displaced from the mold due to the temperature difference due to the heat action of the heat medium. This will improve the sex.
さらには、上記カバー材を金型から外して別の金型にも
流用すれば、金型毎に専用のカバー材を用意する必要が
なくなって、制作費の低減化が図られることとなる。Furthermore, by removing the cover material from the mold and using it for another mold, it is not necessary to prepare a dedicated cover material for each mold, and the production cost can be reduced.
