摘要： PROBLEM TO BE SOLVED: To provide a method for preventing leaking of molten metal from a nozzle of an injection apparatus for metal forming with a plunger therein by operation of the plunger without installing a control system for a nozzle temperature or a valve mechanism.
SOLUTION: This injection apparatus for metal forming is equipped with the plunger movable in cylinder body having the nozzle on its tip and a furnace for melting and holding metallic material provided above a feeding port drilled at the upside of the cylinder body. In the apparatus, the plunger is forcibly set back from its advance limit position to its retreat position located at the rear of the feeding port, while maintaining nozzle touch after completion of injection process. Then molten metal in the melting/holding furnace is flowed into the cylinder body and measured. After completion of measuring, the plunger is moved forward at low speed from its retreat position to waiting position located at the front of the feeding port to close the feeding port. Consequently molten metal between the cylinder body and the melting/holding furnace is blocked off to prevent molten metal leakage from the nozzle.

摘要： PURPOSE:To shorten the time of unit cycle by a method in which the projection of an ejector pin for the first time is mace by usual stroke, and the projection of the projector pin in and after the second time is made by short retracting stroke. CONSTITUTION:A projector pin 3 is provided through a projection plate 6 to a projection pin 5 reciprocally moving inside a cylinder 4 fixed to the movable plate 1 of an injection molding machine. The projector pin 3 is contacted with adjacent switches 9-11 by retraction of a position detecting dock 8 in such a way as to enable it to be regulated from th maximum projection position to the final retraction position (the projection start position). In a sequential action to advance and retract the projector pin 3 plural times, the retracting stroke of the projector pin 3 for the first time is made shorter than the retracting stroke in and after the second time.

摘要： PURPOSE:To make it possible to inspect foreign matters between mold register surfaces in either die plate, by a method wherein a movable die plate and an intermediate die plate are at first closed at the time of mold closing by low mold closing force and the intermediate die plate and the fixed die plate are subsequently closed by mold closing force larger than spring force. CONSTITUTION:In starting inspection, a movable platen 13 is advanced at first and a hydraulic circuit is changed over when a position detector 15 for starting inspection is closed to advance the said movable platen 13 at a low speed under low pressure while a movable die plate 11 is moved with the advance of said platen 13 to push the cores 12 thereof into the cavities 9 of an intermediate die plate 7 and stopped when foreign matters are present on the mold register surface thereof. On the other hand, when foreign matters are absent, a mold closing completion confirmation detector 16 is closed to change over the hydraulic circuit and, at this time, the moval die plate 11 is advanced by mold closing force capable of advancing against the force of a spring 8 and stopped when foreign matters are present between a fixed die plate 2 and the intermediate die plate 7 while a mold closing completion confirmation detector 17 is closed when foreign matters are absent. By this mechanism, inspection of foreign matters on mold register surfaces can be performed by min. mold closing force.
