Abstract

The invention belongs to the field of die control devices, and particularly relates to a die ejector plate forcible returning structure. During die feeding, the end portion of an injection molding machine ejector rod is connected with a connecting piece, a die is moved through a crane, and the connecting piece is pushed into an ejection hole of a movable die bottom plate and is inserted in an installing hole of an ejector plate. The connecting piece is limited in the installing hole in the width direction of the ejector plate through a limiting mechanism, the injection molding machine ejector rod and the ejector plate are connected into a whole, and the ejector rod force directly acts on the ejector plate so that the ejector plate can be ejected. Pull force is provided through the injection molding machine ejector rod to pull the ejector plate back, and the returning action is reliable. During die discharging, only the limiting mechanism needs to be dismounted. By utilization of the die ejector plate forcible returning structure, during die feeding and discharging, the injection molding machine ejector rod does not need to be dismounted or mounted, operation is convenient, the consumed time is short, and the production efficiency is high.

Description

Technical field [0001] The invention belongs to the field of mold control devices, and particularly relates to a strong return structure of a mold ejector plate. Background technique [0002] The injection molding process uses an injection molding machine to inject thermoplastics into a matching mold cavity to process plastic products. After injection molding, the ejector pin is returned by the forced ejection mechanism of the mold ejector plate to prepare for the next injection. The existing mold ejector plate forced return mechanism includes an injection molding machine ejector pin, ejector plate and a movable mold bottom plate with ejector holes. In the upper mold, the ejector pin of the injection molding machine is screwed to the ejector plate, the upper mold is aligned with the hole, and then the ejector pin of the injection molding machine is fixed to the injection molding machine and the mold is closed. The disadvantage of this solution is that the ejector rod of the inj...
