Abstract
The utility model discloses a sand core mold. The sand core mold comprises an overturning-side core box body, a fixed-side core box body, an overturning-side mold frame, a fixed-side mold frame, an overturning-side top core plate, a fixed-side top core plate and an exhaust block, wherein the overturning-side core box body and the fixed-side core box body are distributed at the left side and the right side and abut against each other; the overturning-side mold frame abuts against the outer side of the overturning-side core box body; the fixed-side mold frame abuts against the outer side of the fixed-side core box body; the overturning-side top core plate is arranged on the overturning-side core box body; the fixed-side top core plate is arranged on the fixed-side core box body; a cavity extending from top to bottom is arranged between the overturning-side core box body and the fixed-side core box body; and a nozzle is arranged above the cavity; the exhaust block is positioned below the cavity. The sand core mold disclosed by the utility model has the advantages that since the cavity extending from top to bottom is arranged, sand is ejected into the cavity for molding by the nozzle positioned above the cavity, and the exhaust block positioned below the cavity is used for exhausting gas, so that the gas in the cavity is conveniently exhausted under the sand-ejecting pressure, the ejected sand can be compact, the curing is reliable and further the sand-core yield is improved.
Description
Technical field
The utility model relates to a kind of core mold, especially a kind of core mold with improvement structure.
Background technology
In the existing automobile engine cylinder-body oil passage sand core to thin-long and structure complicated development, this type of loam core is elongated and crooked, changes of section is bigger, is difficult to moulding, it is higher to adopt present mould to make core-breaking rate.Can not mass production.
So, need a kind of new technical scheme to address the above problem.
The utility model content
The purpose of the utility model is the deficiency that exists to prior art, and a kind of core mold of producing elongated type of core yield that improves is provided.
For realizing above-mentioned purpose, the utility model core mold can adopt following technical scheme:
A kind of core mold, arrange about comprising and each other against upset side core box body and fixation side core box body, be resisted against the external side of upset side core box upset side form frame, be resisted against the external side of fixation side core box the fixation side mould bases, be installed on upset side plunger tip plate on the upset side core box body, be installed on fixation side plunger tip plate and exhaust piece on the fixation side core box body; Have the die cavity that extends between said upset side core box body and the fixation side core box body from top to bottom, the top of said die cavity is provided with nozzle, and said exhaust piece is positioned at the below of die cavity.
Compare with background technology; The utility model core mold is penetrated sand through the nozzle that is positioned at the die cavity top and is gone into mold cavity forming through the die cavity that extends from top to bottom is set, and is provided with the exhaust piece that is positioned at the die cavity below and carries out exhaust; Make the gas in the die cavity penetrate discharge under the effect of sand pressure; Can make and penetrate the sand consolidation, solidify reliably, to improve the core yield.
Description of drawings
Fig. 1 is the structural representation of the utility model core mold.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
Shown in accompanying drawing 1; The utility model discloses a kind of core mold 100, arrange about comprising and each other against upset side core box body 20 and fixation side core box body 30, be resisted against upset side core box body 20 outsides upset side form frame 21, be resisted against fixation side core box body 30 outsides fixation side mould bases 31, be installed on upset side plunger tip plate 22 on the upset side core box body 20, be installed on fixation side plunger tip plate 32 and exhaust piece 40 on the fixation side core box body 30.Have the die cavity 50 that extends between said upset side core box body 20 and the fixation side core box body 30 from top to bottom, the top of said die cavity 50 is provided with nozzle 51, and said exhaust piece 40 is positioned at the below of die cavity 50.This core mold 100 also is provided with the some plunger tip posts 61 that are installed on upset side plunger tip plate 22 and the fixation side plunger tip plate 32, also is provided with plunger tip bar 62, return guide rod 63 and plunger tip plate limited post 64 on upset side plunger tip plate 22 and the fixation side plunger tip plate 32.The method for using of the utility model core mold 100 is; In die cavity 50, penetrate sand from nozzle 51, up to reaching die cavity 50 lower bank air parcels 40, the gases in the die cavity 50 are accompanied by penetrates sand pressure through 40 discharges of exhaust piece to sand under the promotion of air pressure; Thereby guiding sand consolidation solidifies reliable; And then in die cavity 50, inject chemical gas from nozzle 51 sand solidified, further improve the intensity of moulding core, can exhaust except the exhaust piece below, other zones seal.Adopt the utility model core mold 100 can significantly improve the core yield,, compare prior art and can significantly improve yield especially to elongated, baroque core.
