Patent JP-S63203312-A (JP)
Title: Control method for pour finish in injection molding
Inventor: ISHIKAWA SHUZO
IPC: B29C45/76
Filed: 1987-02-20
Abstract: PURPOSE:To achieve highly accurate control by a method in which an injection pressure sensor is provided on the tip of an extruder, thereby measuring the resin pressure during injection by the sensor, and when the resin pressure reaches a resin pressure at injection finish which has been measured beforehand, a pouring valve is closed by the signal from the injection pressure sensor, and the pour is finished. CONSTITUTION:A resin 8 extruded from an extruder 2 at a constant pressure is supplied into a mold 1 through an injection pressure sensor 3. The resin pressure detected by the sensor 3 is successively raised as the resin is supplied into the mold 1. The pressure detected by the injection pressure sensor 3 is converted into electric signal in a transducer 4. The electric signal is transferred to a pressure control setting device 6 into which the preliminarily measured, resin pressure at injection finish has been inputted. Here, the pressure of the injection pressure sensor 3 is compared with the resin pressure at injection finish, and when the pressure detected by the sensor 3 reaches the resin pressure of injection finish, a signal is sent to an electromagnetic valve 7 from the pressure setting control device 6, and simultaneously, a valve 5 is closed by the electromagnetic valve 7, thereby stopping the supply of the resin.
