In the docked state, at least a portion of the transition rail 620 is received in the gap between the two transport rails 200 and is docked with the two transport rails 200, respectively. It is understood that the transition rail 620 can fill the gap between the two transport rails 200 so that the rollers 420 smoothly move between the two transport rails 20 through the transition rail 620. And the driver 610 can drive the transition rail 620 to rotate to interface between two transport rails 200 if desired. Specifically, the transition rail 620 is provided with a transition groove 621 in a penetrating manner, when the transition rail 620 is in a butt joint state, two ends of the transition rail 620 are respectively in butt joint with the end surfaces of the two transportation rails 200, and two ends of the transition groove 621 are respectively aligned and communicated with the track grooves 220 on the two transportation rails 200, so that the roller 420 smoothly enters the transition groove 621 from the track groove 220, or smoothly enters the track groove 220 from the transition groove 621.

Specifically, the docking assembly 60 is mounted on the transport rail 200 of the first transport rail 21. In other embodiments, it may also be mounted on the transport rail 200 of the second transport track 22.

Specifically, in the present embodiment, a damper 240 is built in one end of the track groove 220, a buffer 250 is mounted on the damper 240, and the buffer 250 is disposed toward the other end of the track groove 220. Through the arrangement of the baffle 240, the roller 420 cannot be separated from the end of the track groove 220 in the process of moving along the transportation guide rail 200, and the buffer 250 is further arranged on the baffle 240, so that the roller 420 can be buffered and braked when the roller 420 approaches the baffle 240, and the roller 420 is prevented from being damaged due to severe collision between the roller 420 and the baffle 240. For the first transportation rail 21, the baffle 240 and the buffer member 250 are arranged at one end of the rail groove 220 far away from the second transportation rail 22, so that the baffle 240 and the buffer member 250 can form buffer brake on the mold conveying vehicle 40 in the process that the mold conveying vehicle 40 moves from the second transportation rail 22 to the first transportation rail 21.

Further, at an end of the track groove 220 far from the buffer 250, a stopper 260 is rotatably disposed on the transportation rail 200. The stopper 260 can extend into the track groove 220 and cooperate with the buffer 250 to lock the roller 420 in the track groove 220. It can be understood that when the stopper 260 does not extend into the track groove 220, the roller 420 can move away from the buffer 250 and transfer to another transportation track 20; when the limit block 260 extends into the track groove 220, the limit block 260 and the buffer 250 limit the roller 420 from both ends of the mold transporting carriage 40, so as to lock the mold transporting carriage 40 on the transporting track 20.

Specifically, in this embodiment, the stop block 260 is fixedly connected to the transition rail 620 so as to rotate with the transition rail 620 relative to the transport rail 200. When the transition guide rail 620 is in a lifted state, the two transportation rails 20 do not need to be butted, and the limiting block 260 just extends into the rail groove 220, so that the limiting block is matched with the buffer piece 250 to lock the mold conveying vehicle 40; when the transition guide rail 620 is in a butt joint state, the two transportation rails 20 are in butt joint through the transition guide rail 620, and at this time, the limiting block 260 does not extend into the rail groove 220, so that the rail grooves 220 on the two transportation rails 20 are communicated, and the mold conveying vehicle 40 is transferred between the two transportation rails 20.

Furthermore, the limiting block 260 is connected to the transition guide rail 620, the transportation guide rail 200 is provided with an avoiding groove 270 communicated with the rail groove 220, the avoiding groove 270 can avoid the limiting block 260 when the limiting block 260 rotates along with the transition guide rail 620, and the inner wall of the avoiding groove 270 can abut against the limiting block 260 to limit the rotation angle of the transition guide rail 620. The installation manner of the limiting block 260 will be described by taking the transition rail 620 rotatably connected to the transportation rail 200 in the first transportation rail 21 as an example. Transition rail 620 rotates and connects in the upper surface of transportation rail 200, and stopper 260 fixed connection is on transition rail 620, and protrusion in connecting portion 622 and transportation rail 200's rotation junction. The avoiding groove 270 is located at a side of a joint of the transportation rail 200 and the connecting portion 622 away from the second transportation rail 22, and in a process that the transition rail 620 is changed from the butt joint state to the lifting state, the limiting block 260 can extend into the rail groove 220 from the side of the upper surface of the transportation rail 200 along with the rotation of the transition rail 620 through the avoiding groove 270. Thus, the driving of the transition guide rail 620 and the limiting block 260 can be realized simultaneously through the driving part 610, and the dual control of whether the two transportation rails 20 are butted or not and whether the mold conveying vehicle 40 is locked in the rail groove 220 or not is realized, so that the whole structure is simpler and the adjustment is more convenient.

Further, in the process that the transition rail 620 is changed from the butt-joint state to the lifting state, the limiting block 260 can extend into the rail groove 220 from the upper surface side of the transportation rail 200 along with the rotation of the transition rail 620 through the avoiding groove 270, and when the transition rail 620 reaches the lifting state, the limiting block 260 just abuts against the inner wall of the avoiding groove 270, and supports and protects the transition rail 620 in the lifting state.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
