| 摘要 |
<p>The invention relates to an electronic counter (1) or counter, which is excited by the electric signals it receives from a switch, said switch (4) being a pressure switch, preferably a piezoelectric switch that is housed inside the molding chamber (5) in such a way that said switch is not activated by the mechanical closing of the counter mold (6) on the mold (2). Instead, activation of said switch occurs when the molding chamber (5) is flooded with the injection material and the pressure generated by said material on the switch reaches a preset level corresponding to correct injection. Thus, the counter does not count the empty cycles of the mold nor other cycles in which the piece produced is defective due to insufficient injection of material.</p> |
