摘要： An injection molding machine having a simple structure and adapted to quickly operate for injection molding without taking in air bubbles is provided. The injection molding machine comprises a plunger and a nozzle for injecting the molten metal fed from the plunger into a metal mold. The plunger has a cylinder section with a through hole bored through an upper portion of its lateral wall for introducing the molten metal, and a piston for slidingly reciprocating within the cylinder section. A communication hole is bored through the piston and communicates with the through hole at a predetermined position. The communication hole runs from the lateral wall of the piston through the inside thereof and has a non-return valve arranged therein to allow only a flow from the lateral wall of the piston.

摘要： A method and apparatus for controlling the die-retaining force of an extruder is disclosed. In the operation of an extruder adapted to retain a die with a container actuated by a container cylinder and effect extrusion of a billet readied for use in the container by forcing the billet through the die, to keep the die-retaining force of the extruder constant, the control of the die-retaining force of the extruder is carried out by causing the container cylinder to impart to the container a force directed away from the die so as to be sequentially decreased during the first half period of the extrusion and causing the container cylinder to impart to the container a force directed toward the die so as to be sequentially increased during the last half period of the extrusion.

摘要： A hydraulic cylinder mounted on a frame assembly is communicated with a hand operated pump for actuation thereby. A plurality of punch-die assemblies, to be selectively mounted in the frame assembly for perforating, notching clipping or like operations, each comprise a punch or punches carried by a punch holder constrained to up-and-down motion relative to a die. When placed in the frame assembly, any selected punch-die assembly has its punch holder disposed under a ram connected to the piston of the hydraulic cylinder, so that upon manual activation of the pump, the punch or punches can be forced down to perform a desired operation in cooperation with the die. The punch and die assembly has a presser which urges the workpiece against a lateral side of the punch, and the workpiece can be acted upon at two locations at the same time, one location being directly above the other.
