Embodiment Construction

[0017] A tool used to solve the difficulty of mold loosening of large steel casting molds, such as figure 1 As shown: it includes a main frame 2 with a column 1, the end of each column 1 is connected with a screw 3 fitted with a nut, the screw 3 is fixed with a parallel iron 4, and the middle part of the main frame 2 is fixed by a nut. Telescopic threaded screw rod 5, threaded screw rod 5 is equipped with the nut that is fixed with hook 6 at the same end with above-mentioned pad iron 4, and the other end is fixed with handle 7.

[0018] The surface of the horn 4 is covered with rubber, which has the function of height adjustment.

[0019] The main frame 2 is polygonal, and the column 1 is connected to the intersection point of each two sides.

[0020] The main frame 2 is circular, and the four endpoints of its diameter intersecting at right angles are connected with the columns 1 .

[0021] The main frame 2 is elliptical, and the four endpoints of its major and minor axes ar...

Abstract

The invention relates to a tool used in the casting process of a large-scale steel casting, in particular to a tool for solving difficult stripping of a live feed of a large-scale steel casting mould. The tool is characterized by comprising a main skeleton with upright posts; the end part of each upright post is connected with a screw rod matched with a nut; a sizing block is fixed on the screw rod; a telescopic harness screw rod is fixed in the middle of the main skeleton through a nut; and the nut on which a hook is fixed is matched with the same end of the harness screw rod as the sizing block, and a handle is fixed at the other end of the harness screw rod. The tool has the beneficial effects that the structure is special, the use is convenient, the tripping time of a loose piece can be reduced, and the quality of molding sand at the periphery of the loose piece after stripping is ensured.

Description

technical field [0001] The invention relates to a tooling used in the casting process of a large steel casting, in particular to a tool for solving the difficulty in removing the live material of the mold of the large steel casting. Background technique [0002] For the mold used for large steel castings, the main model and the loose block are both large in size. When the box is unpacked, part of the surface of the loose block is surrounded by molding sand. Due to the high friction between the molding sand and the wooden mold, during the process of taking out the loose block, very difficult. At present, on-site operations mainly use tools such as sliding joint screws. Such tools rely on vibration to take out the live blocks bit by bit. The process is time-consuming, laborious, and easy to damage the live blocks. For example, the riser neck of the guide vane casting is ejected. The live block takes about 2 hours and has some damage to the fillet and surface strength; there i...
