For example, it is possible to selectively produce according to different production needs within an effective space, and it can effectively reduce the investment cost of equipment. In the field of railway transportation, many types and large quantities of prefabricated parts are required. For example, laying railways requires sleepers and some other small prefabricated parts (such as covers, fences, square bricks, etc.), which are not only of many types, but also used in large quantities. How to develop a production line that can meet the needs of a variety of prefabricated parts is a technical problem that needs to be solved urgently by those skilled in the art.

[0080] Combine the following Figures 1 to 11 The invention introduces the rollover demoulding equipment, prefabricated parts production line and rollover demoulding method provided by the invention.

[0081] The flip demoulding device provided in the present application includes a first end wall 1, a second end wall 2, a first conveying device and a second conveying device 4. Among them, the first end wall 1 is provided with a first opening 11 penetrating the first end wall 1; the second end wall 2 is opposite to the first end wall 1, and the second end wall 2 is provided with a second opening 21 penetrating the second end wall 2, and the second opening 21 is directly opposite to the first opening 11. The first conveying device is located between the first end wall 1 and the second end wall 2, wherein the conveying path of the first conveying device extends from the first opening 11 to the second opening 21. In a specific implementation, the first conveying device includes a first conveying drive motor 32 and a first conveying unit, the first conveying unit and the first conveying drive motor 32 can be transmission-connected, and the first conveying drive motor 32 is electrically connected to the control unit and controlled by the control unit. The present application arranges the first conveying device between the first end wall 1 and the second end wall 2, and extends the conveying path of the first conveying device from the first opening 11 to the second opening 21. Thus, under the action of the first conveying device, the undemolded preform can be transferred from one of the first opening 11 and the second opening 21 to the flipping station of the flip demolding device, and the demolded mold or the mold table 100 installed with the mold can be transferred out of the flip demolding device from the other of the first opening 11 and the second opening 21.

[0082] like Figures 1 to 3 As shown, the second conveying device 4 is connected to the first end wall 1 and the second end wall 2 respectively and is located between the first end wall 1 and the second end wall 2. Fig.10 As shown, the second conveying device 4 includes a second conveying drive motor 4123 and a second conveying unit 41 directly opposite to the first conveying device, the second conveying unit 41 is transmission-connected to the second conveying drive motor 4123, and the second conveying unit 41 is configured to be able to move toward or away from the first conveying device as a whole. In a specific implementation, the second conveying drive motor 4123 is electrically connected to the control unit and is controlled by the control unit.
