【発明の詳細な説明】
この発明は、絶縁物を製作するために、合成樹脂が注入
される注型金型装置に関するもので、樹脂の注入完了チ
ェックを行なうことを目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a casting mold device in which synthetic resin is injected to manufacture an insulator, and its purpose is to check the completion of resin injection.
第１図は従来の注型金型装置の一例を示すもので、第１

金型（１）に注入される樹脂の注入スピードが非常に重
要になってくる。ところが第１図に示したような従来の
金型においては、樹脂の注入完了チェックを行なうこと
ができず、よって適切な注入スピードが選択できひかっ
た。In such a casting mold, the resin injected from the injection port (4) passes through the molding part (8) and reaches the air pocket (2). Then, the resin that is insufficient due to curing shrinkage is forcibly replenished under pressure from the injection port (4), and the resin is cured through gelation. By the way, in this type of casting method, in order to prevent the generation of voids and internal stress during curing,
The injection speed of the resin into the mold (1) is very important. However, in the conventional mold shown in FIG. 1, it is not possible to check the completion of resin injection, and therefore it is difficult to select an appropriate injection speed.
また、注入時にトラブルがあって注入不良が発生してい
ても、それをチェックすることができなかった。Furthermore, even if there was a problem during injection and an injection failure occurred, it could not be checked.
コノ発明は、このような欠点を解消するためになされた

を行なうようにしたものである。Kono's invention was made to eliminate these drawbacks, and uses glass plates placed on the left and right sides of the air pocket and a photoelectron tube switch that detects the shielding of light between the glass plates. The system is designed to check the completion of resin injection into the mold.

(7Hst is the light emitting part and the light receiving part of the photoelectron tube switch arranged on the side of the through hole (5) in t), (9) is the signal processing and display part. (IQ(lυ indicates the mounting base.

), the light emitted from the light emitting part (7) of the photoelectron tube switch and reaching the light receiving part (8) K is blocked. Become. This displacement signal is then processed by the signal processing/display section [9] to display the completion of S injection.
以上のように本発明によれば、注入完了チェックが確実
に行なえるので、適切な注入スピードを選択することが
できる効果を有する。As described above, according to the present invention, since the completion of injection can be checked reliably, it is possible to select an appropriate injection speed.
なお容量の大きなものについては、上記検出装置を空気
溜り部だけでなく、成型部にも数が新増設することによ

とができる。For large-capacity molds, the state of resin injection into the mold can be continuously measured by installing additional detection devices not only in the air pocket but also in the molding part.
また、金型を直接真空引きして注入するような場合は、
遮へい機構と連動させて使用することにより、真空配管
及び真空ポンプへの樹脂の流れ込みを防止することがで
きる。In addition, when injecting by directly vacuuming the mold,
By using it in conjunction with a shielding mechanism, it is possible to prevent resin from flowing into the vacuum piping and vacuum pump.
なお光電子管スイッチの透過能力は高く、ガラス板が傷
ついたり、１〜２闘稈度の樹脂が付着しても誤動作する
こともない。Note that the photoelectron tube switch has a high transmission ability, and will not malfunction even if the glass plate is scratched or a resin of 1 to 2 degrees of hardness adheres to it.
