Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an automobile door stamping die, includes lower mould 1 and, goes up mould 2 and bottom plate 5, go up 2 for the bolt mounting in the downside of upper die base 4 of mould, 1 for the bolt mounting in the upside of die holder 3 of lower mould, be equipped with die cavity 11 in the lower mould 1, 11 sliding connection in die cavity have push pedal 10, the downside fixedly connected with push rod 7 of push pedal 10, the lower extreme fixedly connected with connecting plate 9 of push rod 7, be connected with spring 8 between the bottom side of connecting plate 9 and die holder 3, spring 8 cup joints on push rod 7, go up mould 2 and 1 phase-match joint of lower mould.
Specifically, guide pillars 12 are fixedly mounted at four corners of the lower die holder 3, guide sleeves 13 are fixedly mounted at four corners of the lower side of the upper die holder 4, the upper ends of the guide pillars 12 are inserted into an inner cavity of the guide sleeves 13, the upper die 2 is a movable die, and the guide pillars 12 play a role in guiding and positioning the movement of the upper die 2.
