Description

Technical Field

[0001] The utility model relates to the technical field of squeeze casting machines, and particularly relates to a protective door of a horizontal squeeze casting machine. Background Art

[0002] Chinese Patent Document No. CN213794156U disclosed a horizontal direct-pressure liquid die forging casting machine on July 27, 2021, which includes a shot mechanism having a shot structure, a shot oil circuit assembly, and a tilting assembly. The fixed template is an integrally cast forming part. The shot structure is hinged to the rear side of the fixed template. The shot structure is respectively matched with the shot oil circuit assembly and the servo motor pump group. The tilting assembly includes a tilting oil cylinder hinged to the rear side and the bottom of the frame. The oil delivery part of the tilting oil cylinder is communicated with the shot oil circuit assembly. The shot oil circuit assembly is communicated with the fuel tank through the servo motor pump group. The control part of the shot oil circuit assembly is connected to the operation electric box. The piston rod part of the tilting oil cylinder is hinged to the shot structure. The protective door of this casting machine is the same as that of a conventional casting machine and is manually controlled. Since the protective door is relatively heavy, it will greatly increase the labor intensity of workers. In addition, the protective doors of some existing casting machines are electrically controlled. Although it can reduce the labor intensity of workers, the protective door is easy to collide with other components when opening or closing, resulting in easy occurrence of accidents.
