Description

A kind of dismounting copper bar vent plug instrument without damaging venting plug hole

Technical field

This utility model relates to casting tool field, more specifically, it relates to a kind of without damaging venting plug hole Dismounting copper bar vent plug instrument.

Background technology

At present, in the copper bar vent plugs such as the mould external form of foundry enterprise, core box are removed and are changed, its traditional tearing open Except method is first to dig rotten copper bar vent plug with " yi word pattern chisel ", then put into copper bar vent plug hole with chisel, Utilize venting plug bore edges as fulcrum, copper bar vent plug remainder is prized.But, due in dismounting During, when using venting plug bore edges to make fulcrum, venting plug bore edges pressure can be collapsed, the core produced Also can highlight fleshiness, increase the workload of core finishing operation；There is also die quality hidden danger, core is uneven simultaneously Whole, the problems such as the visual quality of casting is poor, the serious foundry goods that even results in is scrapped.Another method for dismounting is First dig rotten copper bar vent plug, then with screw tap tapping on copper bar vent plug, utilize screw tap to extract copper bar vent plug.But It is that due to a part of copper bar vent plug tension, or the not reason such as upper tooth attacked by copper bar vent plug, thus causes copper bar Vent plug cannot be removed；Further, from digging rotten copper bar vent plug, to screw tap tapping on copper bar vent plug, silk is utilized Cone extracts copper bar vent plug, and it spends the time long, inefficiency, and inconvenient operation.

Utility model content

The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, it is provided that a kind of structure Simply, easy to make, can rapidly and efficiently realize without damage venting plug hole dismounting copper bar vent plug instrument.

The technical solution of the utility model is such that a kind of dismounting copper bar vent plug work without damaging venting plug hole Tool, including handle, is provided with the chisel suitable with copper bar vent plug in described handle one end, described chisel Each limit is equipped with the edge of a knife that can cut through copper bar vent plug.

As improving further, described chisel is equilateral triangle chisel, and the described edge of a knife lays respectively at The side on this equilateral Atria limit.

Further, the outside diameter that three summits of described equilateral triangle chisel are constituted is less than copper bar gas The outside diameter of plug.

Further, the outside diameter that three summits of described equilateral triangle chisel are constituted and copper bar vent plug The difference of outside diameter be 0.2mm.

Further, described handle is T-type structure.

Beneficial effect

This utility model compared with prior art, has the advantage that

1, by arranging triangle chisel, triangle chisel side edge of a knife operation principle is utilized, by copper bar vent plug Dig into the fragment of one dividing into three, it is achieved remove copper bar vent plug fast and efficiently, effectively save the dismounting time；

2, this chisel outside diameter is than the copper bar little 0.2mm of vent plug outside diameter, can be prevented effectively from removal tool pair Aerofluxus consent causes damage, it is ensured that the quality of mould；

3, this utility model simple in construction, processing and manufacturing is simple, cost is relatively low, volume is little, light weight, and Flexible to operation, practical.

Accompanying drawing explanation

Fig. 1 is the part sectioned view of this utility model front view；

Fig. 2 is the part sectioned view of this utility model top view.

Wherein: 1-handle, 2-copper bar vent plug, 3-chisel, 4-mould.

Detailed description of the invention

This utility model is described further by the specific embodiment in below in conjunction with the accompanying drawings.

Refering to Fig. 1 and Fig. 2, a kind of dismounting copper bar vent plug instrument without damaging venting plug hole of the present utility model, Including handle 1, its handle 1 is set to T-type structure, including cross bar and the montant that is perpendicular to cross bar, it is simple to Operator operate, and can increase handle 1 and weight etc. simultaneously and tap the contact area of thing, make handle 1 stress Evenly；One end of its handle 1 is provided with the chisel 3 suitable with copper bar vent plug 2, and this chisel 3 is in equilateral three Dihedral is fixed on the montant end of handle 1, and is equipped with on each limit of this chisel 3 and can cut through copper bar The edge of a knife of vent plug 2, this edge of a knife lays respectively at the side on this equilateral Atria limit, taps thing at weight etc. Active force under, can quickly cut through copper bar vent plug 2, be effectively improved the dismounting efficiency of copper bar vent plug 2；By such The outside diameter that triangle chisel 3 three summits in limit are constituted is less than the outside diameter of copper bar vent plug 2, and More than the diameter of mould 4 steam vent, can prevent removal tool from copper bar vent plug 2 hole is caused damage, it is ensured that mould Tool 4 quality, specifically, the outside diameter that three summits of this equilateral triangle chisel 3 are constituted with The difference of the outside diameter of copper bar vent plug 2 is 0.2mm, in use, copper bar vent plug 2 can be dug into one and be divided into The fragment of three, thus copper bar vent plug 2 can be extracted easily.This utility model simple in construction, processing and manufacturing be simple, Cost is relatively low, and volume is little, light weight, and flexible to operation, practical.

In the present embodiment without damage venting plug hole dismounting copper bar vent plug instrument, in use, first etc. Limit triangle chisel 3 is put into above the copper bar vent plug 2 of mould 4 and positions；Then, hands is tapped with hammer Handle 1, until 3 copper bar vent plugs 2 of equilateral triangle chisel dig into three parts, then rotary handle 1 loosens triangle Shape chisel 3 also takes out chisel 3, or upwards taps handle 1 with hammer and get chisel 3；Finally, blow with airduct Go out or the copper bar vent plug 2 of one dividing into three chosen by instrument.

Above-described is only preferred implementation of the present utility model, it should be pointed out that for the technology of this area For personnel, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement, These are all without affecting effect and the practical applicability that this utility model is implemented.
