Abstract: In a control device of an injection molding machine, an operation mode of a resin purge operation is adjusted so that a plasticization amount index related to a plasticization amount of resin per unit time in the resin purge operation is approximately accorded with a target plasticization amount index which is set. Accordingly, thermal degradation of resin can be prevented, active time from start of a molding operation to completion of a non-defective molded article can be shortened, and production efficiency can be enhanced. Further, the plasticization amount index is not necessarily set by an operator, so that a load on the operator can be reduced as well.

Abstract: An injector for a plastic material injection molding apparatus whose cylindrical pin-shaped valve that is axially displaceable between an advanced fully closed position and a retracted position of maximum opening, is provided in proximity to a distal end thereof with a reduced diameter cylindrical portion which delimits with the outlet end of the tip of the nozzle terminal an annular passage having a constant cross-section. When the pin valve is between fully closed and maximum opening positions, the reduced diameter cylindrical portion can be selectively positioned in intermediate positions so as to vary the axial extension of the annular passage to adjust the pressure drop of the injected plastic material.

Abstract: A method for producing a clamping member of a hair clip includes filling a plastic material into a cavity defined by a fixed mold and a movable mold, forming a clamping member. The plastic material in rectilinear passages and grooves in the movable mold form teeth on a clamping portion of the clamping member. Then, the movable mold disengages from the fixed mold with the clamping member remaining on the movable mold. Next, the clamping member is moved away from the movable mold by a distance. The plastic material in each groove becomes an elongated section. Before the plastic material completely cures, the clamping member completely disengages from the movable mold. The elongated section of each tooth bends downwards due to gravitational force and completely cures to form a hooked section. The remaining portion of each tooth forms a rectilinear section interconnected between the hooked section and the clamping portion.
