Abstract
The utility model discloses a cylinder water jacket core. The cylinder water jacket core comprises a cold core body, wherein multiple cylinder cup cavities for casting cylinder cups are formed in the cold core body side by side; the axes of the cylinder cup cavities are positioned on a same line; every two adjacent cylinder cup cavities are separated from each other through a sheet hot core; the sheet hot cores are fixedly arranged on the cold core body. The cylinder water jacket core disclosed by the utility model has the advantages of high cold core size accuracy, small deformation and high efficiency and also has the advantages that the hot core strength is high and deformation of a sheet area can be avoided. By virtue of the cylinder water jacket core, the problem that a cylinder water jacket core is large in thickness difference is effectively solved, the advantages of a cold core process and a hot core process are brought into full play, the technical limitation is avoided, and the production efficiency is not influenced by a water jacket core structure.
Description
Technical field
The utility model relates to the core using in a kind of cast blocks technology, relates to specifically a kind of cold core jacket core.
Background technology
At present, the jacket core section thickness of engine cylinder-body is between 6-10mm, and jacket core all adopts cold core process to produce, highly efficient in productivity and casting quality is very stable.But be only the engine cylinder-body of 3mm for some jacket cores thickness between two cylinder cups, if produced with cold core process, in coremaking process, due to thinner herein, sand core strength is inadequate, core will produce top and split or crackle in the time ejecting core box, occurs that the probability thrusting will be very large, and then have a strong impact on casting quality in the casting process of molten metal.
To the mould of jacket core thinner thickness, generally all adopt hot core explained hereafter, to ensure that core has the impact of larger intensity opposing from high-temperature liquid metal, but for some jacket core more complicated, and core box need to design the cylinder body of four opening structures, the layout of its heating tube is very difficult, and the deflection of hot core is larger than cold core, production efficiency is slower, therefore only adopts hot core mold still can not meet casting composite request.
Utility model content
Technical problem to be solved in the utility model is: existing cylinder body cold core core box can not be used for the jacket core that cast thickness is thinner, and hot core core box mould is produced difficulty, and deflection is large, production efficiency is low.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of cylinder body water jacket core, it comprises cold core body, and described cold core body is provided with several for casting the cylinder cup die cavity of cylinder cup, and described cylinder cup die cavity is arranged side by side, and the axle center of described cylinder cup die cavity is located along the same line; Described in two, between cylinder cup die cavity, separate by the hot core of thin slice, the hot core of described thin slice is fixedly installed on described cold core body.
Preferably, the hot core of described thin slice is one-body molded on described cold core body.
Preferably, the both sides that are connected with described cold core body of the hot core of described thin slice are respectively equipped with the enhancing portion for strengthening described cold core body and the hot core bonding strength of described thin slice.
Preferably, described enhancing portion is the groove being arranged on the hot core of described thin slice, and the length direction of described groove is consistent with the axial direction of described cylinder cup die cavity, and described groove is embedded in described cold core body interior.
Preferably, the both sides, end that are connected with described cold core body of the hot core of described thin slice are respectively arranged with a described groove, and described in two, groove is arranged symmetrically with.
Adopt technique scheme, the utility model at least comprises following beneficial effect:
Cylinder body water jacket core described in the utility model, adopt the hot core of thin slice and the combination of cold core body, and directly hot thin slice core one is solidificated in to jacket core inside in the time making cold core body, make like this jacket core of the present utility model both had cold core dimensional accuracy high, be out of shape the advantage little, efficiency is high, there is again hot core intensity high, can avoid the advantage of thin slice district distortion.
brief description of the drawings
Fig. 1 is the structural representation of cylinder body water jacket core described in the utility model;
Fig. 2 is the structural representation of the hot core of thin slice in cylinder body water jacket core described in the utility model.
Wherein: 1. cold core body, the 2. hot core of thin slice, 21. grooves, 3. cylinder cup die cavity.
detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 to Figure 2, for meeting a kind of cylinder body water jacket core of the present utility model, it comprises cold core body 1, and described cold core body 1 is provided with several for casting the cylinder cup die cavity 3 of cylinder cup, described cylinder cup die cavity 3 is arranged side by side, and the axle center of described cylinder cup die cavity 3 is located along the same line; Described in two, between cylinder cup die cavity 3, separate by the hot core 2 of thin slice, the hot core 2 of described thin slice is one-body molded on described cold core body 1.
In the present embodiment, the both sides that are connected with described cold core body 1 of the hot core 2 of described thin slice are respectively equipped with the enhancing portion for strengthening described cold core body 1 and hot core 2 bonding strengths of described thin slice, described enhancing portion is the groove 21 being arranged on the hot core 2 of described thin slice, the length direction of described groove 21 is consistent with the axial direction of described cylinder cup die cavity 3, and described groove 21 is embedded in described cold core body 1 inside.And the both sides, end that are connected with described cold core body 1 of the hot core 2 of described thin slice are respectively arranged with a described groove 21, and described in two, groove 21 is arranged symmetrically with, the top view of the position being connected with described cold core body 1 of the hot core 2 of described thin slice is " work " character form structure substantially, and " work " character form structure of the hot core 2 of described thin slice is molded over the body interior of described cold core body 1.
Because cylinder body water jacket core of the present utility model is combined also one-body molded by the hot core 2 of thin slice and cold core body 1, and hot thin slice core 2 is arranged on to the boundary of two cylinder cup die cavities 3, this cylinder body water jacket core both had cold core dimensional accuracy high, be out of shape little, efficiency is a little high, there is again hot core large in thin slice district intensity simultaneously, the advantage that high-temperature liquid metal impacts can be resisted, cylinder block casting quality can be improved.
Above embodiment of the present utility model is had been described in detail, but the preferred embodiment that described content is only created for the utility model can not be considered to the practical range of creating for limiting the utility model.All equalization variation and improvement etc. of doing according to the utility model creation application range, within all should still belonging to patent covering scope of the present utility model.
