Problems solved by technology

During injection molding, if the inner ring 102 and the outer ring 103 use conventional sliders to distribute the demoulding, then because the size is too small, there is no space for installing the sliders, so normal demoulding cannot be achieved

Abstract

The invention discloses an injection mold for secondary demoulding at the side ribs of a movable mold, comprising a front template (1), a rear template (2), a movable mold core (3), a static mold core (4) and a supporting plate (5 ), the moving mold kernel (3) is fixed with the back template (2), the static mold kernel (4) is fixed with the front template (1), the supporting plate (5) is fixed with the back template (2), and its It is characterized in that it also includes a mandrel (6), a mandrel fixing sleeve (7), a mandrel fixing block (8), a spring (9) and a draw hook (10). The injection mold for the secondary demoulding of the side ribs of the movable mold adopts two-step mold opening, which can ensure the normal demoulding of the barbs of the inner ring and the outer ring, and has a simple structure and good reliability.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with secondary demoulding at the side ribs of a movable mold. Background technique [0002] Such as figure 1 As shown, there is currently a plastic product comprising a body disc 101, an inner ring 102 and an outer ring 103, the inner ring 102 and the outer ring 103 are located at the bottom of the body disc 101, and the inner ring 102 is located in the outer ring 103 and between the two There is a gap, and the side wall of the inner ring 102 is provided with a plurality of notches, so that the inner ring is divided into several sections, and the outer sides of the bottoms of the inner ring 102 and the outer ring 103 have barbs 104 . During injection molding, if the inner ring 102 and the outer ring 103 adopt conventional sliders to distribute the demoulding, since the size is too small, there is no space for installing the sliders, so normal demoulding...
