Abstract

The utility model discloses a composite sand core exhaust needle which is provided with exhaust needles (2), and is characterized in that the plurality of exhaust needles (2) are connected by a connecting plate (5) provided with a handle (6); and the connecting plate (5) is provided with magnet (4). The composite sand core exhaust needle can be used for pricking exhaust holes on a plurality of sand cores at the same time, so that the working efficiency is improved; and the composite exhaust needles are fixed on a mould by the adsorption force of the magnet, so that the composite sand core exhaust needle is time-saving, labor-saving, fast and convenient when being installed.

Description

The compound exhaust needle of core
Technical field:
The present invention relates to be used in a kind of casting industry on core, pricking the exhaust needle in hole.
Background technology:
In Foundry Production, when adopting core shooter to make core, often to prick the hole to core with exhaust needle.Especially a mould multicore need be used a plurality of exhaust needles simultaneously, and exhaust needle in the past is independently single, and is difficult for fixing, and causes its installation effectiveness very low.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of convenience the fixing compound exhaust needle of core.
Technical solution of the present invention is: the compound exhaust needle of a kind of core, be provided with exhaust needle, and a plurality of exhaust needles connect by the connecting plate with handle, are provided with magnet on connecting plate.
The bottom of described exhaust needle is provided with baffle plate, and magnet places between baffle plate and the connecting plate.
The present invention has realized a plurality of cores are pricked steam vent simultaneously, increases work efficiency, and utilizes the absorption affinity of magnet that compound exhaust needle is fixed on the mould, and it is time saving and energy saving, efficient and convenient to install.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Further specify embodiments of the invention below in conjunction with accompanying drawing.
The compound exhaust needle of a kind of core is provided with three exhaust needles 2, and these three exhaust needles 2 connect side by side by the connecting plate 5 with handle 6, and the bottom of each exhaust needle 2 is provided with baffle plate 3, is provided with magnet 4 between baffle plate 3 and connecting plate 5.
Hand-held handle 6 is inserted in core box mould 1 bottom with compound exhaust needle during coremaking, and magnet 4 is adsorbed on the mould, and then compound exhaust needle is fixed; After penetrating sand in a direction indicated by the arrow and making core, exhaust needle is extracted out, made the inner steam vent that forms of core.
