Abstract

The utility model discloses an integrated casting core of an automobile engine flywheel casing, and belongs to the technical field of casting. The core comprises a core body; the core body is formed by a power steering pump hole core, a gear room cavity core, a flywheel observing port core and a starter mounting hole core, which are connected sequentially, in a surrounding manner; the core body adopts an integrated structure, and is provided with a cavity in the middle; and the cavity forms an external profile of the automobile engine flywheel casing. The integrated casting core of the automobile engine flywheel casing decreases cast parting surfaces, and reduces polishing workload; and the appearance of the cast flywheel casing is beautiful.

Description

The monoblock type mo(u)ld core of automobile engine flywheel shell

Technical field

The utility model relates to a kind of monoblock type mo(u)ld core of automobile engine flywheel shell, belongs to casting technology field.

Background technology

At present, the bell housing accessory presentation quality of automobile engine directly affects the presentation quality of whole engine, and 6DL originally, 6DN bell housing castings production are to use outer die cast, puts into four loam cores and piece together whole die cavity in die cavity.Casting flywheel blank somatotype out is many, and burr is large, and presentation quality is just can reach certain standard, but be difficult to meet client's appearance requirement by polishing, polishing.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of die joint that reduces casting is provided, and reduces the polishing workload, and the monoblock type mo(u)ld core of the automobile engine flywheel shell of the bell housing appearance looks elegant of casting.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of monoblock type mo(u)ld core of automobile engine flywheel shell, comprise the loam core body, the loam core body is surrounded by the loam core, power steering pump hole, gear chamber loam core, flywheel observation panel loam core and the starter installing hole loam core that connect successively, the loam core body is the integral type structure, and the middle part of loam core body has the die cavity that forms automobile engine flywheel shell exterior contour.

After having adopted technique scheme, by the process modification to the bell housing mo(u)ld core, a whole loam core is made in four split type loam cores, reduce the die joint of mo(u)ld core, make the die joint of foundry goods all be placed on the machined face, reduce the workload of polishing, and the outward appearance of foundry goods is very attractive in appearance, and the roughness of surperficial casting plane is basically identical, makes the appearance and size of foundry goods unified, solve the bad casting dimension error that causes in lower position, loam core, guaranteed the presentation quality of foundry goods.

Description of drawings

Fig. 1 is the structural representation in the split type loam core of prior art;

Fig. 2 is the structural representation of the monoblock type mo(u)ld core of automobile engine flywheel shell of the present utility model.

The specific embodiment

Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,

As shown in Figure 2, a kind of monoblock type mo(u)ld core of automobile engine flywheel shell, comprise the loam core body, the loam core body is surrounded by the loam core, power steering pump hole 1, gear chamber loam core 2, flywheel observation panel loam core 3 and the starter installing hole loam core 4 that connect successively, the loam core body is the integral type structure, and the middle part of loam core body has the die cavity 5 that forms automobile engine flywheel shell exterior contour.

By the process modification to the bell housing mo(u)ld core, a whole loam core is made in four split type loam cores, reduce the die joint of mo(u)ld core, the die joint of foundry goods all is placed on the machined face, reduce the workload of polishing, and the outward appearance of foundry goods is very attractive in appearance, the roughness of surface casting plane is basically identical, make the appearance and size of foundry goods unified, solve the bad casting dimension error that causes in lower position, loam core, guaranteed the presentation quality of foundry goods.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims

1. the monoblock type mo(u)ld core of an automobile engine flywheel shell, comprise the loam core body, the loam core body is surrounded by the loam core, power steering pump hole (1), gear chamber loam core (2), flywheel observation panel loam core (3) and the starter installing hole loam core (4) that connect successively, it is characterized in that: the loam core body is the integral type structure, and the middle part of loam core body has the die cavity (5) that forms automobile engine flywheel shell exterior contour.
