Description

technical field [0001] The invention relates to an injection mold, in particular to a combined core-pulling mechanism in the horizontal and vertical directions of the injection mold. Background technique [0002] If one side of the plastic part is formed with horizontal undercut and vertical undercut at the same time, the existing technology is to make the vertical undercut into an arc-shaped groove, set a slide block on the core, and be shaped on the slide block. Side core pulling and upper core pulling, so that when the mold is opened, the power drives the slider to be drawn out horizontally. If the inner wall of the direction undercut is made into a sharp angle or a right angle, it will not be able to come off, and if it is forced to come off, the plastic part may be broken, which will affect the product quality. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and to provide a kind of inclined gu...

[0002] If one side of the plastic part is formed with horizontal undercut and vertical undercut at the same time, the existing technology is to make the vertical undercut into an arc-shaped groove, set a slide block on the core, and be shaped on the slide block. Side core pulling and upper core pulling, so that when the mold is opened, the power drives the slider to be drawn out horizontally. If the inner wall of the undercut is made into a sharp angle or a right angle, it will not be able to come out, and if it is used forcibly, it may cause the plastic parts to be broken and affect the product quality
