Abstract

It the utility model is related to mould applications, disclose a kind of left outside core of engine cylinder-body, including core and running gate system, described running gate system includes sprue and sprue cup, funnel shaped sprue cup endoporus is provided with sprue cup, sprue cup endoporus is communicated with sprue, and described sprue cup is integrally formed with core, and its sprue cup is shaped as up-narrow and down-wide trapezoidal stage body.Because sprue cup and core are integrally formed, reduce the process and the bonding process of core and sprue cup for making sprue cup, improve the yield rate of casting, reduce production cost and cost of labor.And integrally formed sprue cup uses up-narrow and down-wide cylinder, adds the contact area of sprue cup and core, increases the stability of sprue cup and core junction, ensure that in casting process, sprue cup is not turned over by molten iron punching, improves production efficiency.

Description

A kind of left outside core of engine cylinder-body
Technical field
It the utility model is related to mould applications, and in particular to a kind of left outside core of engine cylinder-body.
Background technology
The left outside core of traditional engine cylinder-body separates with sprue cup, in cast, by manually smearing bonding Agent bonds together core and sprue cup, occurs that bonding agent smearing is more in bonding process, causes bonding agent to overflow, Bonding agent carries out die cavity by sprue during cast, causes casting to scrap;Either bonding agent is smeared less, and sprue cup is viscous loosely Gu or cast gate and the bottom misalignment of sprue cup endoporus in bonding, in cast, sprue cup is turned over by molten iron punching, causes casting can not Shaping;And when bonding compresses sprue cup, friction that sprue cup or core are also easy to produce makes molding sand fall into sprue, caused Product rejection.
In summary, the sprue cup of traditional separate type is cumbersome in use, and product is easily scrapped, and increases Sprue cup production process and core and sprue cup bonding process.
Utility model content
The purpose of this utility model is:For above-mentioned separate type sprue cup existing technical problem in use, The utility model provides a kind of left outside core of engine cylinder-body.
The technical solution adopted in the utility model is as follows:A kind of left outside core of engine cylinder-body, including core and cast system System, described running gate system includes sprue and sprue cup, is provided with funnel shaped sprue cup endoporus on sprue cup, in sprue cup Hole is communicated with sprue, and described sprue cup is integrally formed with core, and its sprue cup is shaped as up-narrow and down-wide trapezoidal stage body.
By adopting the above-described technical solution, the beneficial effects of the utility model are:Described sprue cup uses with core It is integrally formed, the endoporus of sprue cup is communicated with sprue, and the process and type for making sprue cup are reduced while realizing and pouring into a mould The bonding process of core and sprue cup, the yield rate of casting is improved, reduces production cost and cost of labor.And it is integrally formed Sprue cup use up-narrow and down-wide trapezoidal stage body, add the contact area of sprue cup and core, increase sprue cup and type The stability of core junction, ensure that in casting process, and sprue cup is not turned over by molten iron punching, improves production efficiency.
Brief description of the drawings
Fig. 1 is the utility model structure diagram;
Fig. 2 is the utility model section schematic diagram;
Marked in figure:1- cores, 2- sprues, 3- sprue cups, 4- sprue cup endoporus.
Embodiment
All features disclosed in this specification, can be with any in addition to mutually exclusive feature and/or step Mode combines.
The utility model is elaborated below in conjunction with the accompanying drawings.
The utility model is a kind of left outside core of engine cylinder-body, including core 1 and running gate system, described cast system System, including sprue 2 and sprue cup 3, are provided with funnel shaped sprue cup endoporus 4, sprue cup endoporus on described sprue cup 3 4 are communicated with sprue 2, and sprue cup 3 is integrally formed with core 1, and its sprue cup 3 is shaped as up-narrow and down-wide trapezoidal stage body.
In casting process, liquid metal enters from sprue cup 3, enters running gate system by sprue cup endoporus 4, realization is poured Note process.Compared with traditional core, the utility model reduces the making of sprue cup 3 and the bonding work of sprue cup 3 and core 1 Sequence, the yield rate of casting is improved, reduces production cost and cost of labor.And integrally formed sprue cup 3 for it is upper it is narrow under Wide trapezoidal stage body, adds the connectivity of sprue cup 3 and core 1, ensure that in casting process, sprue cup is not rushed by molten iron Turn over, reduce casting scrappage, improve production efficiency.
It is embodiment of the present utility model as described above.The utility model is not limited to above-mentioned embodiment, anyone The structure change made under enlightenment of the present utility model should be learnt, it is every that there is same or like skill with the utility model Art scheme, each falls within the scope of protection of the utility model.
