Description

Technical Field

[0001] This utility model relates to a vehicle headlight pressing device, and in particular to a dual-station pressing device for automotive headlights. Background Technology

[0002] During the manufacturing process of automotive lights, the lamp cover and lamp housing need to be assembled into one piece through gluing and pressing. During the pressing process, glue may overflow onto the mold on which the lamp cover or lamp housing is placed, causing the mold to be contaminated. When cleaning the mold, the pressing machine needs to be stopped, which reduces the efficiency of the automotive light pressing. Moreover, the existing pressing machine has a one-to-one correspondence between the upper and lower mold bases. The lamp cover and lamp housing can only be placed after the automotive light is removed after pressing is completed, which is inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-station pressing device for automotive headlights that improves the pressing efficiency of headlights.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A dual-station pressing device for automotive headlights includes a worktable, a frame fixed on the worktable, a top plate fixed on the frame, and a lifting cylinder fixed on the top plate. The cylinder has a vertically extendable cylinder shaft, a lifting plate fixed to the lower end of the cylinder shaft, and an upper mold base fixed to the lower surface of the lifting plate. A work plate is provided on the worktable, a guide rail is provided on the work plate, a movable plate is provided on the guide rail, and a sliding block is provided at the lower end of the movable plate that can slide on the guide rail. A first lower mold base and a second lower mold base are fixed on the movable plate. A lifting cylinder is fixed to the lower surface of the work plate, and the lifting cylinder has a vertically movable lifting cylinder shaft. A connecting plate is provided at the upper end of the lifting cylinder shaft, and a first positioning plate, a second positioning plate, and a third positioning plate are fixed on the connecting plate. A first positioning groove and a second positioning groove are provided on the movable plate.

[0006] With the above structure, the second lower mold base is initially positioned below the upper mold base. When the upper mold base presses the lamp housing in the second lower mold base, the operator can first place the lamp housing to be pressed onto the first lower mold base. After the lamp housing is pressed onto the second lower mold base, the lifting cylinder raises the upper mold base. At this time, the lifting cylinder simultaneously lifts the first positioning plate, the second positioning plate, and the third positioning plate through the connecting plate. The first positioning plate disengages from the first positioning groove, and the second positioning plate disengages from the second positioning groove. The operator pushes the moving plate to align the first lower mold base with the upper mold base. The lifting cylinder lowers the first positioning plate, the second positioning plate, and the third positioning plate. At this time, the second positioning plate falls into the first positioning groove, and the third positioning plate falls into the second positioning groove. The operator then places the lamp housing to be pressed onto the upper mold base to begin the lamp pressing work. During the lamp pressing process, the operator can clean the second lower mold base and place the lamp housing, etc. This utility model improves the efficiency of cleaning the lower mold base and the efficiency of lamp pressing.

[0007] Preferably, in order to facilitate the positioning of the moving plate after movement, a limit block is provided on the working plate.

[0008] Preferably, in order to facilitate the positioning of the movable plate after it has been moved, the movable plate is provided with a first positioning mark and a second positioning mark. Attached Figure Description

[0014] like Figures 1 to 4As shown, the dual-station pressing device for automotive headlights of this utility model includes a worktable 1, a frame 2 fixed on the worktable, a top plate 3 fixed on the frame, and a lifting cylinder 4 fixed on the top plate. The cylinder has a cylinder shaft 5 that can extend and retract vertically. A lifting plate 6 is fixed to the lower end of the cylinder shaft. An upper mold base 7 is fixed to the lower surface of the lifting plate. A work plate 8 is provided on the worktable. A guide rail 9 is provided on the work plate. A moving plate 10 is provided on the guide rail. A sliding block 11 that can slide on the guide rail is provided at the lower end of the moving plate. A first lower mold base 12 and a second lower mold base 13 are fixed on the moving plate. A lifting cylinder 14 is fixed to the lower surface of the work plate. The lifting cylinder has a lifting cylinder shaft 15 that can move vertically. A connecting plate 16 is provided at the upper end of the lifting cylinder shaft. A first positioning plate 17, a second positioning plate 18, and a third positioning plate 19 are fixed on the connecting plate. A first positioning groove 20 and a second positioning groove 21 are provided on the moving plate.

[0015] In some embodiments, such as Figures 1 to 3 Limiting blocks 22 are provided on the working plate.

[0016] In some embodiments, such as Figure 1 and Figure 3 As shown, the movable plate is provided with a first positioning mark 23 and a second positioning mark 24.

[0017] With the above structure, the second lower mold base is initially positioned below the upper mold base. When the upper mold base presses the lamp housing in the second lower mold base, the operator can first place the lamp housing to be pressed onto the first lower mold base. After the lamp housing is pressed onto the second lower mold base, the lifting cylinder raises the upper mold base. At this time, the lifting cylinder simultaneously lifts the first positioning plate, the second positioning plate, and the third positioning plate through the connecting plate. The first positioning plate disengages from the first positioning groove, and the second positioning plate disengages from the second positioning groove. The operator pushes the moving plate to align the first lower mold base with the upper mold base. The lifting cylinder lowers the first positioning plate, the second positioning plate, and the third positioning plate. At this time, the second positioning plate falls into the first positioning groove, and the third positioning plate falls into the second positioning groove. The operator then places the lamp housing to be pressed onto the upper mold base to begin the lamp pressing work. During the lamp pressing process, the operator can clean the second lower mold base and place the lamp housing, etc. This utility model improves the efficiency of cleaning the lower mold base and the efficiency of lamp pressing.
