The mavable module core in injection mold and fixed mold core are often heated to a higher temperature, wherein, it is contemplated that in thimble and forming cavity
Plastic cement contact area it is smaller, the flowing of plastic cement will not be impacted substantially, therefore thimble is not heated, also
It is to say, the thimble temperature of itself does not have too big change.
Because the temperature of thimble itself is basically unchanged, the size of the thimble is also basically unchanged, when the temperature of mavable module core raises
When, the mavable module core can produce dilatancy so that the aperture of the through hole coordinated on the mavable module core with thimble reduces, that is to say, that
The hole wall of this through hole can excessively expand to the direction where thimble, so as to cause the hole wall of the through hole with thimble being bonded tightly,
Although the Wen Duxiajiang of follow-up mavable module core can be such that the hole wall of through hole is inside contracted to the direction away from thimble, this inside contracts amplitude much
Less than its expansion amplitude, therefore, the hole wall of the through hole being bonded tightly still with thimble, increase in thimble ejection process with hole
Frictional resistance between wall, easily cause the stuck damage of thimble.
