【発明の詳細な説明】
〈産業上の利用分野〉
本発明は、ダイカスト鋳造機やプラスチック□ 成型
機などに使用される成型用金型に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a mold for use in die casting machines, plastic molding machines, and the like.
〈従来の技術〉
ダイカスト鋳造やプラスチックの射出成型では、製品の
品質を安定させ且つ生産性を向上させる為に金型の温度
（以下、型温と略称する）を常時最適の範囲に維持させ
なければならない。<Conventional technology> In die casting and plastic injection molding, the temperature of the mold (hereinafter referred to as mold temperature) must always be maintained within an optimal range in order to stabilize product quality and improve productivity. Must be.
この型温は、本来ならば射出直前のキャビティ表面の温
度を測定したものを言うが、従来では製品取出し直後の
キャビティ表面の温度を測定して代用しているのが現状
である。Originally, this mold temperature refers to the temperature measured on the surface of the cavity immediately before injection, but in the past, the temperature on the surface of the cavity immediately after the product was taken out has been measured and used as a substitute.
しかし乍ら、従来のような型温検知方法では、製品取出
し直後のキャビティ表面の温度経時変化が著しく且つ金

ける温度が著しく異なるために、的確な型温を測定し管
理することは不可能であり、多分に経験と勘に頼ってい
るのが現況である。However, with conventional mold temperature detection methods, the temperature of the cavity surface changes significantly over time immediately after the product is taken out, and the temperature at each measurement point varies markedly depending on the shape and size of the mold (cavity). Currently, it is impossible to measure and control mold temperature, and we rely largely on experience and intuition.
そこで、例えば特公昭５３−２６０９号公報に開示され
た如き、金型の鋳壁面下に熱電対を埋設させた鋳物冷却
時間の制御装置が考えられた。しかし乍ら、この装置で

して金型の鋳壁面下に熱電対を埋設する為の穴を加工形
成することは非常に難しく、しかも金型の強度及び精度
保持のためにも金型の鋳壁面下に穴を穿つことは好まし
くない。Therefore, a device for controlling the cooling time of a casting was devised, for example, as disclosed in Japanese Patent Publication No. 53-2609, in which a thermocouple is embedded under the casting wall of a mold. However, with this device, special processing must be performed on the mold, and as a practical matter, it is extremely difficult to process and form a hole for embedding a thermocouple under the casting wall of the mold. In order to maintain the strength and precision of the mold, it is not preferable to drill holes under the casting wall of the mold.
〈発明が解決しようとする問題点〉

自体の変換が簡便に行なえる金型を提供せんとするもの
である。<Problems to be solved by the invention> The present invention was made in view of the current situation, and it is possible to measure the temperature of the cavity surface immediately before injection, that is, the mold temperature, in real time, and to accurately determine the mold temperature. To provide a mold that can be controlled, does not require special processing on the mold itself, and can easily change the installation location of the thermocouple or convert the thermocouple itself. It is something.

いことは理解されるべきである。Thermocouples (5) for measuring the mold temperature are built into the pins at desired locations among the large number of extrusion pins (4) or core pins. That is, the inside (6) of the required extrusion pin (4) or core pin is formed into a hollow shape, and the thermocouple (5) is housed and installed in the inside (6). A long extrusion pin (4) or core pin is formed so that it can be divided into a tip part (4a) and the other part (4b), and a thermocouple (5) is stored inside it (6). You are free to make it easier to install.Also, thermocouples (
The number and location of the extrusion pins (4) or core pins in which the cavity (3) is incorporated are appropriately selected depending on the shape and size of the cavity (3). In addition to the extrusion pin (4) or the core pin, a pin specially formed in order to achieve the purpose of the present invention is installed in the cavity (3) by the same means as the core pin, and the pin is It should be understood that a thermocouple (5) may be incorporated inside.
