Description

Technical Field

[0001] The utility model relates to a 3D printing sand mold transport and flipping tool, belonging to the technical field of sand mold printing equipment. Background Art

[0002] In recent years, with the development of 3D printing technology, many samples and small batch castings are developed and trial-produced using 3D printed sand molds, which greatly saves the development cycle and mold opening costs. The largest sand mold that can be printed is 2000*1000*1000mm, and the quality of the printed sand mold can reach 200-500Kg.

[0003] After the sand mold is printed, it needs to be taken out from the printing sand box, and later it needs to be transported, turned over, and boxed; however, in the prior art, the taken out sand mold is not fixed by the traditional sand box, and there are great inconveniences in the later transportation and turning process. For example, the sand mold is easily damaged during transportation, and it is not easy to turn over, which makes the operation difficult.

[0004] Therefore, we proposed a 3D printing sand mold handling and flipping tool. Utility Model Content

[0005] The purpose of the utility model is to provide a 3D printing sand mold handling and flipping tooling to solve the 3D printing sand mold handling and flipping problems, reduce production costs, and improve production efficiency.

The two lower ends of the hanging rod are rotatably installed with connecting rods through corresponding support shafts. A support rod is arranged between the two connecting rods, and the support rod is used to support and fix the sand mold, and the connecting rod can rotate along the support shaft.

[0007] In the aforementioned 3D printing sand mold handling and turning tooling, two support rods are provided, and the two support rods are provided at both ends of the connecting rod. The two support rods can support and fix the sand mold more stably.

[0008] The aforementioned 3D printing sand mold handling and turning tooling also includes a sand mold, and the side wall of the sand mold is provided with a through hole, and the through hole corresponds to the support rod. When the sand mold is printed, two through holes are reserved, and the support rod is passed through the through holes of the sand mold to support the sand mold.

[0009] The aforementioned 3D printing sand mold handling and turning tooling has a hanging device on the top of the boom, which is convenient for connection and handling by machinery such as lifting equipment and hoisting equipment.

[0010] The aforementioned 3D printing sand mold handling and flipping tooling. A locking device corresponding to the connecting rod is provided on the outer side of the end of the hanging rod. The locking device can fixedly lock the connecting rod to prevent the sand mold from flipping during handling. When flipping is required, only the locking device needs to be opened.

[0011] The aforementioned 3D printing sand mold handling and flipping tooling. The locking device includes an ear plate. Ear plates are provided on both sides of the end of the hanging rod. The ear plates are arranged parallel to the connecting rod. The ear plate is provided with an installation hole, and a limiting rod is inserted into the installation hole. A limiting hole is provided on the side wall of the connecting rod, and the end of the limiting rod is inserted into the corresponding limiting hole.

[0012] The aforementioned 3D printing sand mold handling and flipping tooling. A sliding groove is provided on the bottom side wall of the limiting rod. A moving slider is slidably installed in the sliding groove. A jack corresponding to the moving slider is provided on the side wall of the installation hole. There are at least two jacks.
