[0002] In the design process of die castings, it is necessary to consider the casting fillet, demoulding angle, wall thickness of die castings and other aspects, which will have an important impact on the subsequent production of die castings. In the design process of die castings, it is necessary to improve the local quality of the castings or some structures on the castings are too complex to be demolded.
[0003] In the related art, in order to solve the above problems, a solution of an oil pipe embedded aluminum alloy die-cast shell (Announcement No. CN216938347U) was discovered. During die-casting, the position of the embedded oil pipe inside it is not easy to shift under the fixation of the fixed structure, and a channel structure such as an installation groove will be generated in the area of the embedded oil pipe. The interior of the shell is opened up by embedding the embedded oil pipe, which is convenient for the later use of the workpiece, thereby improving the practicality of the shell.
[0004] However, in the above scheme, the die-cast shell body is directly surrounded by the embedded oil pipe during die-casting. Since the embedded oil pipe is U-shaped, when the aluminum alloy die-cast shell needs to be inspected and maintained, the embedded oil pipe cannot be disassembled, and the embedded oil pipe and the die-cast shell can only be replaced as a whole. In addition, when cleaning oil stains, the bent shape of the embedded oil pipe makes cleaning difficult. Utility Model Content
