Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

As shown in fig. 1 to 2, the utility model relates to a delayed demolding mechanism for a slider, which comprises an upper mold 1 and a lower mold 2, wherein an inclined guide post 11 is arranged on the upper mold 1, a slider 21, a slider limit screw 22, a first insert fixing plate 24 and a second insert fixing plate 25 are arranged on the lower mold 2, the slider 21 can move back and forth on the lower mold 2 without departing from the lower mold 2, an inclined hole is arranged on the slider 21, the inclined guide post 11 passes through the upper mold 1, extends into the inclined hole, extends out of the inclined hole and extends into the lower mold 2, the inclined guide post 11 is used for following the upper mold 1 to move and further drive the inclined guide post 11 to move left and right, the slider limit screw 22 passes through the slider 21, extends out of the slider 21 and is fixed on the second insert fixing plate 24, the slider limit screw is used for limiting the distance between the second insert fixing plate 25 and the slider 21, in order to perform the delayed demolding operation, a limit screw spring 223 is disposed between the second insert fixing plate 25 and the slide block 21, the limit screw spring 223 is sleeved on the slide block limit screw 22, the limit screw spring 223 is used for buffering the distance between the second insert fixing plate 25 and the slide block 21, so that the slide block 21 and the second insert 27 are in close contact after mold opening is performed, one side of the first insert fixing plate 24 is fixed to one side of the slide block 21, the first insert fixing plate 24 is used for fixing the first insert 21, and the second insert fixing plate 25 is used for fixing the second insert 27.
