Abstract
The utility model relates to a casting aluminum cylinder block sand core structure suitable for supporting a hot cylinder sleeve. A casting mould comprises a crank case sand core, a front end face core, a rear end face core, a cylinder sleeve supporting core and a top cover core and is characterized in that by taking the crank case sand core as the positioning base, the front end face core is placed at the left side of the crank case sand core, and the rear end face core is placed at the right side of the crank case sand core; a cylinder sleeve to be heated is placed on a boss of the crank case sand core to be prepositioned; the cylinder sleeve supporting core is arranged in the cylinder sleeve; the cylinder sleeve and the cylinder sleeve supporting core are tightly fit; and casting is started after the top cover core is placed. By adopting the structure, the placement precision of the hot cylinder sleeve on the sand core is improved, and the operation is simple and convenient. The structure is suitable for producing an aluminum cylinder block on which the cylinder sleeve is inlaid and cast.
Description
Technical field
The utility model relates to the casting aluminum cylinder sand core structure of the hot cylinder sleeve of a kind of suitable support, belongs to the technical field of casting aluminum cylinder castingin cylinder sleeve.
Background technology
Many castingins of aluminum cylinder cylinder sleeve, high-pressure casting and metal-mold low-pressure casting, metal mold gravity casting adopt manipulator that cylinder sleeve is placed on and pour into a mould after mould supports the cylinder sleeve position, and multiple-core casting utilizes the special construction core of design to support cylinder sleeve more.
Summary of the invention
The utility model purpose provides the casting aluminum cylinder sand core structure of the hot cylinder sleeve of a kind of suitable support, has improved the precision that hot cylinder sleeve is placed on core, and is easy and simple to handle, is fit to the aluminum cylinder production of castingin cylinder sleeve.
The technical solution of the utility model is achieved in that the casting aluminum cylinder sand core structure that is fit to support hot cylinder sleeve, casting mold is made up of crankcase core, front end face core, rear end face core, cylinder sleeve supporting-core, top cover core, it is characterized in that: with the crankcase core is the basis, location, the front end face core is placed in the left side, the rear end face core is placed on the right side, the cylinder sleeve of heating is placed on pre-determined bit on the crankcase core boss, the cylinder sleeve supporting-core is placed in the cylinder sleeve, cylinder sleeve and cylinder sleeve supporting-core fit tightly, place the top cover core then, begin cast.
Gapped between described crankcase core boss and cylinder sleeve, cylinder sleeve does not contact with boss.
Described cylinder sleeve supporting-core 4 is four, and its stage casing does not contact with cylinder sleeve.
Good effect of the present utility model is to have improved the precision that hot cylinder sleeve is placed on core, and is easy and simple to handle, is fit to the aluminum cylinder production of castingin cylinder sleeve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, be fit to support the casting aluminum cylinder sand core structure of hot cylinder sleeve, casting mold is made up of crankcase core 1, front end face core 2, rear end face core 3, cylinder sleeve supporting-core 4, top cover core 5, it is characterized in that: with crankcase core 1 is the basis, location, front end face core 2 is placed in the left side, rear end face core 3 is placed on the right side, the cylinder sleeve of heating is placed on pre-determined bit on crankcase core 1 boss, cylinder sleeve supporting-core 4 is placed in the cylinder sleeve, cylinder sleeve 6 fits tightly with cylinder sleeve supporting-core 4, place top cover core 5 then, begin cast.
Gapped between described crankcase core boss and cylinder sleeve, when placing cylinder sleeve, cylinder sleeve does not contact with boss, again cylinder sleeve supporting-core 4 is put into cylinder sleeve, and cylinder sleeve 6 coolings are shunk, and are close to cylinder sleeve supporting-core 4 surfaces.
Described cylinder sleeve supporting-core 4 is four, and its stage casing does not contact with cylinder sleeve, slows down the heat conduction of cylinder sleeve to the cylinder sleeve supporting-core, reduces the cylinder sleeve cooling rate, and the top cover core is a benchmark with front end face core 2 and rear end face core 3, puts into other cylinder sleeve 6 and cylinder sleeve supporting-core 4 successively.
The position of the position of fine-tuning crankcase core 1 core print seat and adjustment top cover core 5 during work, the position of fine-tuning cylinder sleeve; Adjust the diameter of cylinder sleeve supporting-core 4, can guarantee that cylinder sleeve supporting-core 4 can insert in the cylinder sleeve 6 smoothly under hot cylinder sleeve state, and cylinder sleeve 6 suitably is close on the cylinder sleeve supporting-core 4 after the cooling.
Claims (3)
1. be fit to support the casting aluminum cylinder sand core structure of hot cylinder sleeve, casting mold is made up of crankcase core, front end face core, rear end face core, cylinder sleeve supporting-core, top cover core, it is characterized in that: with the crankcase core is the basis, location, the front end face core is placed in the left side, the rear end face core is placed on the right side, and the cylinder sleeve of preheating is placed on pre-determined bit on the crankcase core boss, and the cylinder sleeve supporting-core is placed in the cylinder sleeve, cylinder sleeve and cylinder sleeve supporting-core fit tightly, and begin cast behind the placement top cover core.
2. the casting aluminum cylinder sand core structure of the hot cylinder sleeve of suitable support according to claim 1 is characterized in that between described crankcase core boss and cylinder sleeve gappedly, and cylinder sleeve does not contact with boss.
