Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as Figure 1-Figure 2 As shown, the disc casting molding device includes an inner gate 1 communicating with the casting cavity 9 of the disc casting. The top of the casting cavity 9 is provided with an air outlet riser 10 communicating with the inside, which can increase the production rate of the casting process produced by the casting of disc castings, and there will be no sand holes, slag holes, and pores on the top surface of the casting cavity. Surface casting defects, production efficiency and quality can meet its requirements. The air outlet riser 10 is a truncated cone-shaped structure penetrating up and down, and the top of the truncated cone-shaped structure is larger than the bottom. The upper and lower through structure of the truncated cone-shaped structure is also a truncated truncated through-hole structure with the top part larger than the...

Abstract

A disk type casting molding device comprises an inner gate communicating with a casting cavity of a disk type casting; and an air outlet riser runner communicating with the interior of the casting cavity is formed in the top of the casting cavity. The air outlet riser runner is of a vertically-through circular truncated cone structure, and the top of the circular truncated cone structure is largerthan the bottom of the circular truncated cone structure. One end of the inner gate communicates with the casting cavity, and the other end of the inner gate communicates with a scum riser. The scumriser is of a hollow arch-shaped flat-bottom structure. A scum feeder head communicates with the top of the scum riser. A filter net is arranged between the scum riser and the scum feeder head. The filter net is a ceramic filter net of a cylinder structure. By combining other structures, the defects that in the prior art, the process yield of castings produced by disk type casting molding is about50%, the top planes of casting cavities easily have the surface casting defects of sand holes, scum holes and gas holes, and the production efficiency and quality cannot meet the requirements easilyare effectively overcome.

Description

Technical field [0001] The invention relates to the technical field of small and medium-sized castings, in particular to a disc casting moulding device, in particular to a disc casting moulding production device. Background technique [0002] In the casting production process of disc castings, core assembly is a very critical process. The accuracy of the castings and the economic effect of the entire production process mainly depend on this process. Specifically, the molding production process of disc castings is usually flat molding, plane pouring, and the riser position is placed in the center of the casting cavity of the disc casting, or the riser position is placed in the casting mold of the disc casting At the rim of the cavity, the casting process yield rate is about 50%, and the top surface of the casting cavity is prone to surface casting defects such as sand holes, slag holes, and pores. The production efficiency and quality are difficult to meet its requirements. Summa...
