確な温度測定が可能となる。Next, the operation of the temperature sensor 64 will be described. As shown in FIG. 5, when the fixed die 14a of the insert die 14 is mounted in the fixed die body 10 having the temperature sensor 64 attached to the positioning member 18b from the direction of arrow A, the fixed die 1
4a is fixed to the positioning member 18b before the fixed mold 14a
The bottom of the measurement hole 88 provided as a temperature measurement part and the heat sensitive part 56 are in contact with each other. The coil spring 82 is in the most contracted state until the bottom of the measurement hole 88 and the heat-sensitive portion 56 come into contact with each other. Further, the temperature measuring portion is usually formed in a hole toward the cavity as in this embodiment so as to be as close as possible to the cavity where the resin is injected. Due to the contact with the bottom of the measurement hole 88, the heat-sensitive part 56 is fixed to the fixed mold 1.
Although it is pressed in the direction of arrow A by 4a, the pressing force is applied to the coil spring 82 arranged between the movable portion 72 and the fixing means 84 via the cable 66. Then, the coil spring 82 is extended in the direction of arrow B as shown in FIG. 6, so that the heat-sensitive portion 56 moves inside the attachment portion 54 until the fixed die 14a comes into contact with the positioning member 18b as the fixed die 14a moves. Is pushed into. Therefore, the heat-sensitive portion 56
The heat-sensitive portion 56 will not be damaged due to excessive force applied to the heat-sensitive portion 56. Further, the heat sensitive portion 56 is constantly repelled in the direction of the fixed die 14a by the coil spring 82, and the heat sensitive portion 56 is surely in contact with the inner wall surface of the measurement hole 88 of the fixed die 14a, so that accurate temperature measurement can be performed. .

可能となる。Further, even when the fixed mold 14a is replaced and the depth of the measurement hole 88 is changed by the above structure,
Since the amount of protrusion of the heat-sensitive portion 56 automatically changes according to the depth of the measurement hole 88, it is not necessary to remove the temperature sensor 64 every time the fixed mold 14a is replaced and change the amount of protrusion as in the conventional case. It is possible to quickly perform the replacement work of the child mold 14.
