Abstract
The utility model relates to casting technology field, particularly relate to a kind of drilling device, a kind of casting mould drilling device, comprise handle and drilling device main body, described drilling device main body lower end is blade, described drilling device main body is the structure of elliptical table shape, handle is arranged near blade, the fin structure that the side of described drilling device main body major axis is born in addition, best, the length of described drilling device main body elliptical table shape structure major axis is greater than 2 times of the length of minor axis, and such casting mould drilling device has the advantage using spreading range that is more convenient, hole large; The fin structure that the side of described drilling device main body major axis is born in addition, has the advantage that the spreading range in hole is larger.
Description
Technical field
The utility model relates to casting technology field, particularly relates to a kind of drilling device.
Background technology
When casting, can produce some gases in die cavity, need punch on mould with drilling device before casting, these gases are just discharged from hole, thus ensure normally carrying out of casting; In prior art, be pyramidal structure below the drilling device used, want the area increasing hole, drilling device will be made downwards to run, but the degree of depth of operation is often restricted, and has awkward shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of and uses the casting mould drilling device that spreading range that is more convenient, hole is large.
The technical solution of the utility model is achieved in that a kind of casting mould drilling device, comprise handle and drilling device main body, described drilling device main body lower end is blade, it is characterized in that: described drilling device main body is the structure of elliptical table shape, and handle is arranged near blade.
Say further, the fin structure that the side of described drilling device main body major axis is born in addition.
Best, the length of the major axis of described drilling device main body elliptical table shape structure is greater than 2 times of the length of minor axis.
The beneficial effects of the utility model are: such casting mould drilling device has the advantage using spreading range that is more convenient, hole large; The fin structure that the side of described drilling device main body major axis is born in addition, has the advantage that the spreading range in hole is larger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Wherein: 1, handle 2, drilling device main body 3, blade 4, wing;
The length of D-minor axis;
The length of L-major axis.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of casting mould drilling device, comprises handle 1 and drilling device main body 2, and described drilling device main body lower end is blade 3, it is characterized in that: described drilling device main body is the structure of elliptical table shape, and handle is arranged near blade 3.
Can press down when rotating during such use the utility model, will increase and decrease the size in hole like this, owing to being elliptical table shape structure, the size of increase is more, has advantage of the present utility model.
Say further, wing 4 structure that the side of described drilling device main body major axis is born in addition, it is more that such hole just can increase as required.
Best, the length L of the major axis of described drilling device main body elliptical table shape structure is greater than 2 times of the length D of minor axis.
Above embodiment is only section Example of the present invention, but aim of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed in the scope of the claims of the present invention.
Claims (2)
