Die thimble stuck, knock can not knock out how to do?
Should it be stuck inside the mold core?Consider the whole immersion in hot oil for a while and then try knocking again. (the thermal expansion rate of the thimble is different from that of the mold core)It is not, can consider the cut method for wire cut WE, then a larger number in the cut position of the thimble.
The space is enough, the thimble enlarges a model, re - wire cut.
You can drill it with a drill
