Title: Temperature control method for injection mold
Inventor: NAKAGAWA TATSUJI
IPC: B29C45/73
Filed: 1992-07-17
Abstract: PURPOSE:To allow a mold temperature at the time of injection charging a molten resin into a mold to rapidly converge to a target temperature without fluctuating to accomplish a high-accuracy molded article. CONSTITUTION:At the time of injection charging a molten resin, a mold temperature is raised to a target temperature by passing a steam to a mold 1. After the injection molding, the mold temperature is lowered to a molded article removal temperature by passing a cooling fluid to the mold 1. In this mold temperature control method, the heating of the mold 1 is started by supplying a steam through steam lines 12-14, and the pressure of the steam to be supplied to the mold 1 is lowered by a pressure reducing valve 10 when the mold temperature approximates the target temperature. In this manner, the reduction of the steam temperature allows the mold temperature to converge to the target temperature.

IPC: F16H57/02
Filed: 1983-10-14
Abstract: PURPOSE:To increase the air suction speed by fixing a member having a convergence part at one edge into an air bleed passage. CONSTITUTION:During high-clutch operation, the operation pressure reaches an air bleed passage 2 and presses a ball 5 onto a convergence part 4a. Therefore, the cut of a high clutch operation pressure from the center hole of a member 4 is prevented, and the high-clutch operation is not influenced by an air bleed apparatus consituted of an air bleed passage 2, member 4, ball 5, and a pin 6. When the high clutch operation is suspended by the dissipation of the high clutch operation pressure, the ball 5 is separated from the convergence part 4a and dropped onto the pin 6 by the gravity. Then, air is drawn into the air bleed passage 2, and the high clutch operation pressure sharply dissipates.
