Abstract
The utility model discloses a closing plug comprising a steel ball and a plug body. A cavity is formed in hollow of the plug body; external diameter of the steel ball is larger than diameter of the plug body cavity. When the steel ball plugs into the cavity, sidewall of the plug body is pressed and connected with holes requiring blocking. During application of the closing plug, firstly the plug body is plugged into the hole of the model, then the steel ball is plugged into the cavity of plug body, at the time side wall will expand and communicate firmly with blocking hole and gap between the closing plug and the hole is sealed, therefore the hole is completely blocked. The structure is simple ands easy for application with good seal effect.
Description
Technical field
The utility model relates to a kind of sealing plug.Especially a kind of sealing plug that in mould, is used to stop up the cooling liquid hole.
Background technique
In some Mould design are made, cooling water or oil groove can be set, be provided with a plurality of water or oily holes that are used to discharge or carry cooling usefulness in the water or the oil groove position of mould accordingly, these holes can be selected according to the needs of actual mould installation or cooling, then need to carry out shutoff if any unnecessary hole.For these holes of shutoff, generally be tap out on the hole at present, screw in screw with the screw sealing plug that is tied with leakproof glue then.But there is certain problem in said method, and the tapping of screw bothers on the one hand, and the hole that more especially has tapering can't be adopted, and sealing effect is also bad, and after long-term the use, leakproof glue may cause seepage because of wearing out on the other hand.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing plug, and is simple in structure, easy to use, and good sealing effect.
The utility model is to realize above-mentioned purpose like this:
Sealing plug is characterized in that comprising cock body and steel ball, and described cock body hollow shape becomes cavity, and the external diameter of steel ball is greater than the diameter of cock body cavity, and after steel ball was filled in cavity, the sidewall of cock body was extruded and expands and the hole clamping that needs to stop up.
As improvement of the technical scheme, the outer surface of cock body is provided with ring tooth.
The beneficial effects of the utility model are: the sealing plug in use, earlier cock body is filled in the hole of mould, then steel ball is squeezed in the cock body cavity by force, the sidewall of cock body was extruded expansion and needed the hole of obstruction to be connected together firmly and the sealing that the gap between sealing plug and the hole is tight this moment, realized the shutoff in this hole.This structure is very simple, use also very convenient, and good sealing effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is that the utility model is placed on the schematic representation in the hole;
Fig. 3 is the schematic representation after the utility model and hole clamp.
Embodiment
Referring to figs. 1 through Fig. 3, sealing plug comprises cock body 1 and steel ball 2, and described cock body 1 hollow shape becomes cavity 11, and the external diameter of steel ball 2 is greater than the diameter of cock body cavity 11.Sealing plug in use, earlier cock body 1 is filled in the hole 3 of needs obstruction of mould, then steel ball 2 is squeezed in the cavity 11 of cock body 1 by force, the sidewall of cock body 1 is connected together firmly by the internal surface in the hole 3 of steel ball 2 extrusion expansions and needs obstruction and with the tight sealing in gap between sealing plug and the hole 3, realizes the shutoff in this hole 3 at this moment.This structure is very simple, uses also very conveniently, has removed troubles such as needing tapping in the prior art from, and good sealing effect, uses safelyr, does not have the sorrow of aging seepage.
In order further to make sealing plug be more prone to use, the outer surface of cock body 1 is provided with ring tooth 12.Compare with the sealing plug that does not have ring tooth, the position of ring tooth 12 was more prone to distortion, caves in when steel ball 2 was squeezed into, and sealed to be more prone to.
In addition, for the ease of steel ball 2 easier being driven in the cavity 11, the diameter of described cavity 11 open-mouths is big than the diameter in the cavity 11, form shoulder position 13, earlier steel ball 2 is placed on cavity 11 than the major diameter place during use, beat steel ball 2 exposed parts then with strength, steel ball 2 impels the sidewall distortion to realize sealing with regard to being squeezed into the less part of cavity 11 diameters.
