出される。[Description] A temperature sensor such as a thermocouple can be used as the extruded resin detector. That is, since the filling resin has a high temperature, it is detected by the detector 5 of the temperature sensor.
When it reaches 1,52 ---, etc., it is immediately detected.
また、充填樹脂は高い圧力で押出されるから、圧力計も
検知器５１，５２−−−−として用いることができる。Moreover, since the filling resin is extruded at a high pressure, a pressure gauge can also be used as the detectors 51, 52.
要するに、絶縁樹脂４０が到達する前と後の状態の変化
を検出できるものであれば、検知器５１，５２−−−−
として用いることができる。In short, if it is possible to detect a change in state before and after the insulating resin 40 arrives, the detectors 51, 52 -----
Can be used as
検知器は、少なくとも金型内に送り込まれた樹脂の到達
が最も遅い箇所に、取り付けるようにする。The detector should be installed at least at the position where the resin sent into the mold reaches the latest.
樹脂の到達が最も遅い位置は、従来の実験から分かって
おり、第１図のように、樹脂の入口が金型の中央にある
場合は、金型内面の左右両端の上部、すなわち、検知器
５１，５２の位置である（後記参照）。The position where the resin arrives the slowest is known from a conventional experiment. When the resin inlet is at the center of the mold as shown in Fig. 1, the upper part of the left and right ends of the inner surface of the mold, that is, the detector. The positions are 51 and 52 (see later).
ただし、第１図の場合は、さらに左右両端の下部にも、
検知器５３，５４を設けている。However, in the case of FIG.
Detectors 53 and 54 are provided.
当然に、金型の端から注入する場合は、樹脂の到達の最
も遅い箇所は金型の他端になる。As a matter of course, in the case of injecting from the end of the mold, the place where the resin reaches the latest is the other end of the mold.
［作用］ 押出された樹脂が、金型２０の端部に到達すると、検知

できる。[Operation] When the extruded resin reaches the end of the mold 20, the detectors 51 to 54 detect the temperature and pressure of the resin, and the instruction changes. Therefore, the completion of filling can be detected.
なお、押出された樹脂は、必ずしも金型２０内面の左右
