Embodiment 1

[0026] Embodiment one, see figure 1 , a car roof mold, including an upper mold base 1, a movable push plate 2, a sunroof puncher 3, a suspension bolt 31 and a binder plate 4.

[0027] The upper mold base 1 is provided with a second gas spring 11 extending vertically. There are three second gas springs 11 . The upper mold base 1 is also provided with a positioning protrusion 12 .

[0028] The plane where the movable push plate 2 is located extends along the horizontal direction. The left end of movable push plate 2 is connected with switching cylinder 21. The switching cylinder 21 extends in the left-right direction. The lower surface of the movable push plate 2 is provided with a first jacking projection 22 . The first lifting protrusions 22 have three rows and are distributed along the left and right directions. There are five first jacking bumps in each row of first jacking bumps 22 . The first lifting bump 22 is provided with a strip-shaped via hole 23 extending alon...

Embodiment 2

[0034] Embodiment two, the difference with embodiment one is:

[0035] see Figure 4 , On the upper mold base 1, a push rod 5 is also worn. The push rod 5 can move forward and backward (perpendicular to the paper direction) and left and right. A connecting block 24 is arranged between the movable push plate 2 and the push rod 5 . The connecting block 24 connects the movable push plate 2 and the push rod 5 together.

[0036] The sunroof punch 3 comprises an upper half 36 and a lower half 37 . The upper half 36 and the lower half 37 are overlapped together in the vertical direction.

[0037] see Figure 5 , the first jacking bump 22 and the second jacking bump 34 are elongated structures. The first jacking bump 22 and the second jacking bump 34 are parallel. The extending direction of the first lifting protrusion 22 is perpendicular to the telescoping direction of the switching cylinder.

[0038] The connecting hole 35 is composed of an upper section 351 (the upper secti...

Abstract

The invention relates to equipment for automobile production, in particular to an automobile top cover die which comprises an upper die seat and a skylight puncher. A movable pushing plate and a switching cylinder driving the movable pushing plate to move in the horizontal direction are further arranged on the upper die seat, the skylight puncher is connected under the upper die seat in a lifting mode, the movable pushing plate is located between the upper die seat and the skylight puncher, a first jacking convex block is arranged on the lower surface of the movable pushing plate, and a second jacking convex block matched with the first jacking convex block is arranged on the upper end face of the skylight puncher. The automobile top cover die can meet production requirements of top covers with skylights and top covers without skylights, and solves the problem that two sets of dies are needed for top covers with skylights and top covers without skylights of the same automobile type.
