Example Embodiment

[0026] Example 1, see figure 1 , An automobile roof mold, including an upper mold base 1, a movable push plate 2, a sunroof punch 3, a suspension bolt 31 and a pressing plate 4.

[0027] The upper mold base 1 is provided with a second gas spring 11 extending in the vertical direction. There are three second gas springs 11. The upper mold base 1 is also provided with positioning protrusions 12.

[0028] The plane on which the movable push plate 2 is located extends in the horizontal direction. A switching cylinder 21 is connected to the left end of the movable push plate 2. The switching cylinder 21 extends in the left-right direction. The lower surface of the movable push plate 2 is provided with a first lifting bump 22. The first jacking bumps 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 jacking bump 22 is provided with a bar-shaped via 23 extending in the left-...

Example Embodiment

[0034] The second embodiment is different from the first embodiment:

[0035] See Figure 4 , The upper mold base 1 is also provided with a push rod 5. The push rod 5 can move in the front and rear (perpendicular to the paper direction) and left and right directions. A connecting block 24 is provided 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 includes an upper half 36 and a lower half 37. The upper half 36 and the lower half 37 are stacked together in the vertical direction.

[0037] See Figure 5 , The first jacking bump 22 and the second jacking bump 34 are both elongated structures. The first jacking bump 22 and the second jacking bump 34 are parallel. The extension direction of the first jacking block 22 is perpendicular to the expansion and contraction direction of the switching cylinder.

[0038] The connecting hole 35 is composed of an upper section...

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.
