Referring to fig. 9 and 11, since the first elbow 210a is an aluminum alloy profile, and the bottom side structure of the first elbow 210a is relatively complex, in order to achieve the attachment of the first elbow 210a and the first curved wall 21a, the first curved wall 21a is divided into three sections along the first direction, correspondingly, the first profiling mold 20a is divided into three sections along the first direction, the three sections of the first profiling mold 20a are sequentially attached along the first direction, the first mold frame 100 is disposed on a side of the first profiling mold 20a away from the second profiling mold 20b, the first mold frame 100 is vertically mounted on the base 10, and the three sections of the first profiling mold 20a are sequentially attached and locked to the first mold frame 100 by fasteners. In addition, one side of the first mold frame 100, which is away from the base 10, extends to the first pressing mold 50a and is attached to the first pressing mold 50a along the first direction, so that the first mold frame 100 covers the left side of the first mold cavity 70a, and the first mold frame 100 can also be used as a left side limit of the first elbow 210 a. The second copying die 20b is constructed in the same manner as the first copying die 20a, and since the width of the second bend 210b is smaller than that of the first bend 210a, the number of the second copying dies 20b is two, and the others are the same as the first copying dies 20a, and will not be described again here.

Referring to fig. 10, the rotating frame 30 includes a mounting plate 32 and two rotating arms 31, the two rotating arms 31 are disposed at intervals along a first direction and are respectively rotatably connected to the base 10, the two rotating arms 31 are respectively disposed at the outer sides of the first profiling mold 20a and the second profiling mold 20b, the mounting plate 32 is connected to one end of the two rotating arms 31 departing from the base 10, and the mounting block 40 is mounted on the mounting plate 32. In operation, the first driving member 130 drives the two rotating arms 31 to rotate, so as to drive the mounting plate 32, the mounting block 40, the first die 50a, the second die 50b, the first die core 60a and the second die core 60b to rotate.

Referring to fig. 10, two rotating shaft seats 110 are disposed on the base 10, a rotating shaft is disposed on the rotating shaft seats 110, slots 111 are disposed on the rotating shaft seats 110, the rotating shaft penetrates the slots 111, one end of the rotating arm 31 away from the mounting plate 32 is inserted into the slots 111 and sleeved on the rotating shaft, and the first driving member 130 is connected to the rotating shaft, so that when the first driving member 130 drives the rotating shaft to rotate, the rotating arm 31 can be driven to rotate around the rotating shaft. This application is through setting up slot 111 on pivot seat 110, then can reduce the center of rotation axis, and the rotation axis coincides with the central axis of curved surface wall 21 to can reduce the height of curved surface wall 21, and then make whole sunroof rail's elbow former occupation space little.

In the embodiment, the first mold core 60a, the second mold core 60b, the first profiling mold 20a and the second profiling mold 20b are all made of steel, and the hardness is HRC 56-58 degrees, so that the hardness and the wear resistance of the first mold core 60a, the second mold core 60b, the first profiling mold 20a and the second profiling mold 20b are improved, and the service life of the elbow forming equipment of the sunroof guide rail of the automobile is further prolonged.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
