Title: Method for ejecting molded article in injection molding machine
Inventor: KAMIGUCHI MASAO
IPC: B22D17/32
Filed: 1994-10-26
Abstract: PURPOSE: To provide an ejector device, with which a molded article can be surely released from a mold in a short period of time without developing deformation even when the article bites the mold severely. CONSTITUTION: A mold release work is carried out under the condition that an ejector pin 6 is projected and vibrated so as to give vibration to a molded article 7. Since the mold release is carried out by gradually peeling the molded article 7 from a movable mold 8 without applying impact force several times to the molded article 7, no deformation such as plucking and the plunging-in of the ejector pin 6 develops even when the molded article 7 bites the mold severely and sure mold release work can be carried out in a short period of time. In addition, since the inertial applying to the molded article 7 at its mold release is finally small, the molded article 7 after the completion of mold release is prevented from scattering.
