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

A kind of for solving the large-scale steel-casting mould instrument that material is difficult to molding of living

Technical field

The present invention relates to the frock used in a kind of large-scale steel-casting casting process, especially relate to a kind of for solving the large-scale steel-casting mould instrument that material is difficult to molding of living.

Background technology

The mould that large-scale steel-casting uses, the equal size of agent model and loose piece is larger, and when unpacking, the loose piece part surface is surrounded by molding sand, and is because frictional force between molding sand and the wooden model is large, in the process of taking out loose piece, very difficult.At present, execute-in-place mainly adopts the instruments such as sliding connection screw rod, and this type of instrument relies on vibrations that loose piece is bit by bit taken out, consuming time in the process, effort, easily damage loose piece, such as the molding of guide vane casting pressing port neck, each loose piece probably needs 2 hours, and fillet and surface strength are destroyed to some extent; The way that does not also address this is that at present.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of structure unique, easy to use, can reduce loose piece stripping time, guaranteed after the molding molding sand quality around the loose piece a kind of for solving the large-scale steel-casting mould instrument that material is difficult to molding of living.

In order to realize goal of the invention, the present invention realizes in the following way:

A kind of for solving the large-scale steel-casting mould instrument that material is difficult to molding of living, it is characterized in that: it comprises the main framing with column, the end of each column all is connected with the screw rod that is combined with nut, be fixed with parallels on the screw rod, the middle part of main framing is fixed with a harness cord screw rod that can stretch by nut, the harness cord screw rod is combined with the nut that is fixed with hook at the same end with above-mentioned parallels, and the other end is fixed with handle;

The surface of described parallels is covered with rubber;

Described main framing is polygon, is connected with described column on the intersection point on its every both sides;

Described main framing is circular, is connected with described column on four end points of the diameter that it intersects at a right angle;

Described main framing is oval, is connected with described column on four end points of its major and minor axis.

The present invention has following effect:

1) structure is unique: it comprises that it comprises main framing with column device provided by the invention, the end of each column all is connected with the screw rod that is combined with nut, be fixed with parallels on the screw rod, the middle part of main framing is fixed with a harness cord screw rod that can stretch by nut, the harness cord screw rod is combined with the nut that is fixed with hook at the same end with above-mentioned parallels, and the other end is fixed with handle.

2) easy to use: as when device provided by the invention uses the parallels screw rod to be placed on the molding sand, nut ring and loose piece are hung nose link to each other; Reach molding sand situation on every side according to the loose piece position, adjust the length of parallels screw rod, make harness cord screw rod direction and loose piece number of unmolulding directions be in a line; Simultaneously, hold-down nut is fastened to rational position, prevents that the harness cord screw rod from moving up and down; Swing handle, the nut that the harness cord screw rod reaches with hook moves up, and the drive loose piece hangs nose and loose piece is outwards mobile, thereby loose piece is taken out from molding sand.

3) can reduce loose piece stripping time: device solves provided by the invention loose piece long problem stripping time in the past, such as the molding of guide vane casting pressing port neck, early stage, each probably needed 2 hours, use this instrument after, only need about 15 minutes;

4) guaranteed after the molding molding sand quality around the loose piece: dress man provided by the invention has solved the problem of damaging loose piece fillet, loose piece edge and internal soundness after the in the past loose piece molding.

Description of drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is that the present invention uses view.

The specific embodiment

A kind of for solving the large-scale steel-casting mould instrument that material is difficult to molding of living, as shown in Figure 1: it comprises the main framing 2 with column 1, the end of each column 1 all is connected with the screw rod 3 that is combined with nut, be fixed with parallels 4 on the screw rod 3, the middle part of main framing 2 is fixed with a harness cord screw rod 5 that can stretch by nut, harness cord screw rod 5 is combined with the nut that is fixed with hook 6 at the same end with above-mentioned parallels 4, the other end is fixed with handle 7.

The surface of described parallels 4 is covered with rubber, and the height of adjustment function is arranged.

Described main framing 2 is polygon, is connected with described column 1 on the intersection point on its every both sides.

Described main framing 2 is circular, is connected with described column 1 on four end points of the diameter that it intersects at a right angle.

Described main framing 2 is oval, is connected with described column 1 on four end points of its major and minor axis.

As shown in Figure 2: use procedure is as follows:

Prepare draw arm;

Parallels 4 is placed on the molding sand 10, the nut that is fixed with hook 6 is hung nose 9 with loose piece link to each other;

Reach molding sand situation on every side according to the loose piece position, adjust the length of parallels 4, make harness cord screw rod 5 directions and loose piece 8 number of unmolulding directions be in a line; Simultaneously, with being fixed with hook 6 fastening nuts to rational position, prevent that harness cord screw rod 5 from moving up and down;

Swing handle 7, harness cord screw rod 5 and be fixed with hook 6 nut and move up drives that loose piece hangs nose 9 and loose piece 8 is outwards mobile, thereby loose piece 8 is taken out from molding sand.
