Title: Method and apparatus for controlling first molding transition in injection molder
Inventor: EGI TADAO
IPC: B29C45/77
Filed: 1986-10-28
Abstract: PURPOSE:To prevent a mold from breaking by a method wherein the predetermined number of shots of molding are continuously done by the preset filling pressure for preforming when the detected filling pressure reaches the predetermined value and, after that, molding under normal molding conditions is restored. CONSTITUTION:When an actual filling pressure reaches the pressure limit value set at a pressure limit value setter 46, a controller 48 changes over by means of the command issued by a comparator 26 from normal molding conditions to preforming conditions, and set values issued by a pressure setter 54 for preforming and by a number-of-shot setter 56 for preforming are inputted to a servo amplifier 24. Thus, no shots, the number of which is set at the number-of-shot setter 56 for preforming, of injection filling are performed by the filling pressure for preforming, which is set at the pressure setter 54 for preforming. After the completion of n times of injection filling, the controller 48 is changed over so as to perform molding under normal molding conditions, which are set by a speed setter 50 for normal molding and by a pressure setter 52 for normal molding. Thus, since no excessively large abnormal filling pressure develops, a mold can be prevented from breaking.
