The member 45 does not slide and move on the inclined surface 28b, and the inclined surfaces 28a and 42b contact each other only after the movable die 30 and the fixed die 20 are clamped. As described above, since the inclined surfaces 28a and 42b are formed not as sliding surfaces but as pressure-bonding surfaces, problems such as abrasion and cutting of the seal member 45 due to sliding can be prevented. Further, since the structure for moving the sealing member back and forth is unnecessary, the structure of the entire mold can be simplified, and the step of moving the sealing member back and forth is also unnecessary, and the number of steps required for mold clamping can be suppressed. be able to.

ことができる。Further, the seal between the slide core and the movable die can be realized simply by crimping the slide core to the movable die,
Similarly, since the seal between the slide core and the fixed die can be realized only by crimping the slide core to the fixed die, it is not necessary to separately provide a cylinder or the like for advancing and retracting the seal ring, and the entire die can be provided. The configuration can be simplified and the number of mold clamping steps can be minimized.
Further, since the seal member is provided so as to make one round continuously with the flat surface and the inclined surface of the slide core, the seal member can completely seal between the slide core and the movable mold or the fixed mold. it can.

きる。According to the die seal structure of the second aspect, since the convex portion of the slide core is clamped in a state where the convex portion of the slide core is accommodated in the stationary accommodating portion, the slide core moves due to the casting pressure. Can be prevented. Therefore, in the mold closed state, the seal ring is kept in a static state, and its fatigue deterioration can be prevented.
