Abstract
The utility model discloses an air exhaust plug with a central hole. The air exhaust plug comprises an air exhaust plug cylinder body (1) and a filter screen cover (2), wherein the filter screen cover (2) is fixed at one end of the filter screen cover (2). The air exhaust plug is characterized in that a central hole (3) is arranged at the center of the filter screen cover (2). The utility model has the advantages that the air exhaust plug is arranged in a mandril hole of a mould (4); a mandril (5) can pass through the central hole (3) of the air exhaust plug to support a sand core (6); and meanwhile, the air of the sand core (6) also can be discharged by filter meshes on the periphery of the central hole (3) of the air exhaust plug. The air exhaust plug better solves the problems that if the air exhaust plug is arranged at any position, no position of the mandril exists, and if the mandril is arranged, no position of the air exhaust plug exists.
Description
Technical field:
Supporting apparatus when the utility model relates to metal type dies system core, venting plug when relating in particular to make core specifically is a kind of venting plug with centre bore.
Background technology:
In sand mo(u)ld casting industry, when making the core of core box, because the shape of core and the restriction of area, if arranged venting plug, just there is not the position of push rod at some position, if arranged that push rod does not just have the position of venting plug, make the core producer be in the dilemma, because there is not push rod will cause core to be scrapped,, might cause the impaired waste product that becomes of foundry goods again if there is not venting plug.
The utility model content:
The technical problems to be solved in the utility model is that when making the core of core box, because the shape of core and the restriction of area, the needs to the core of these privileged sites is made provide a kind of venting plug with centre bore at above-mentioned.
Technical solution of the present utility model is:
The venting plug of band centre bore comprises venting plug cylindrical shell and filtering screen, and filtering screen is fixed on an end of cylindrical shell, it is characterized in that: described filtering screen center is provided with centre bore.
After adopting above structure, compared with prior art, the utlity model has following advantage: the venting plug that this band centre bore has been arranged, this venting plug is arranged in the jogger hole of mould, the centre bore that push rod can pass venting plug supports core, simultaneously, filtration mesh around the venting plug centre bore can be discharged core " getting angry " in the same old way, solved some special position preferably if arranged that venting plug does not just have the position of push rod, if arranged that push rod does not just have the double-barreled question of the position of venting plug.
Description of drawings:
Accompanying drawing is the venting plug user mode schematic diagram of the utility model band centre bore.
Shown in the figure: 1, venting plug cylindrical shell, 2, filtering screen, 3, centre bore, 4, mould, 5, push rod, 6, core.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Shown in the accompanying drawing, the venting plug of the utility model band centre bore comprises venting plug cylindrical shell 1 and filtering screen 2, and filtering screen 2 is fixed on an end of cylindrical shell 1, it is characterized in that: described filtering screen 2 centers are provided with centre bore 3.
When installing and using, this venting plug is arranged in the jogger hole of mould 4, the centre bore 3 that push rod 5 can pass venting plug supports core 6, simultaneously, filtration mesh around the venting plug centre bore 3 can be discharged core 6 " getting angry " in the same old way, solved some special position preferably if arranged that venting plug does not just have the position of push rod, if arranged that push rod does not just have the double-barreled question of the position of venting plug.
