Device for demolding negatives in thermoplastic injection molds

Abstract

The device for demolding negatives in thermoplastic injection molds includes an ejector (3), which comprises an ejector profile (5) for the fastening thereof to an ejector plate (2), and a figure insert (6) with a profile that is complementary to the piece (4) to be molded, wherein said ejector (3) further comprises a flexible element (7) arranged between the ejector profile (5) and the figure insert, which pushes said figure insert (6) in order to demold the negative by means of angular displacement and stretches said figure insert (6) so as to return the ejector (3) to the injection position thereof. It makes it so molding sliders are no longer necessary, hence, these spaces, the costly sliders, and the painstaking machining processes for the installation thereof in the molds are no longer required.
