Embodiment Construction

[0035] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0036] Such as figure 1 , 2 Shown, a kind of casting method of flywheel, its process steps are as follows:

[0037] a, make the upper sand shell: make it on a core shooter, so as to obtain the upper sand shell S. In this step, the upper sand shell S is a structure of revolution, the upper part of the upper sand shell S is the gate section, and the lower part is the disk part.

[0038] b. Making the lower sand shell: make it on another core shooting machine with the same structure, so as to obtain the lower sand shell X. In this step, the lower sand shell X is a structure of revolution, and the middle part of the lower sand shell X has an annular inner cavity.

[0039] c. Make the gate: put molding sand in the gate mold, and make the gate after heating. This step is a routine step, that is: first heat the gate mold at a temperature of 200°C-350°C; then put ...

Abstract

The invention discloses a casting method for a flywheel. The casting method comprises the following steps: a, preparing an upper sand shell: manufacturing on a core shooting machine to prepare the upper sand shell; b, preparing a lower sand shell: manufacturing on another core shooting machine to prepare the lower sand shell; c, manufacturing a sprue; d, closing a die: putting the lower sand shell into a lower iron shell; covering the top of the lower sand shell with the upper sand shell; after closing the upper sand shell and the lower sand shell, forming a cavity for casting the flywheel; then covering a sprue section of the upper part of the upper sand shell with an upper iron shell; finally, tightly pressing the upper iron shell and the lower iron shell with a U-shaped clip; e, arranging the sprue; f, pouring; g, de-molding: taking out a flywheel casting blank; h, cleaning the sprue. According to the casting method for the flywheel, casting defects of sand clamping, slag clamping, air pores, loosening and the like in a traditional casting process can be effectively prevented; the casting method for the flywheel is efficient and low in cost; the effective utilization rate of molten iron is high; in a technological process, the core shooting machine is improved on the basis of outsourcing; the improved core shooting machine can be used for preventing the defect that a sand spraying nozzle is blocked by humid hardening of a sand covering film.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a casting method of a flywheel. Background technique [0002] Flywheels are widely used in the automotive field. The current production methods of flywheels mostly use casting, and the usual casting methods are as follows, that is: use tidal sand metal molds for modeling, and arrange gates and risers according to the feeding system of conventional casting. The disadvantage of this casting method is that it consumes a lot of energy, the utilization rate of molten iron is too low when the work is wasted, and there are many casting defects, such as sand inclusions, slag inclusions, pores, and looseness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency, low-cost flywheel casting method, and solve casting defects such as air holes and slag inclusions existing in the traditional casting method. [0004] ...
