Example Embodiment

[0021] The technical solutions of the present invention are further described below, but the claimed scope is not limited to the description.

[0022] like figure 1 Shown is the structural schematic diagram of the present invention:

[0023] The present invention provides a composite pouring system, which includes a bottom box 1, a middle box, and an upper box 4 stacked in sequence. The bottom box 1, the middle box, and the upper box 4 form a cavity 5 inside. There is a downwardly open main runner 6, the upper part of the main runner 6 is connected with a bottom runner 7 and a conformal runner 8, and the conformal runner 8 is arranged along the bottom of the cavity 5; A first vertical runner 9 and a bottom casting runner 10 are provided. The two ends of the bottom casting runner 10 are respectively connected to the cavity 5 and the conformal runner 8, and the lower end of the first vertical runner 9 is connected to the bottom runner 7. The side surface of the first vertical ...

Abstract

The invention provides a composite casting system which comprises a bottom box, a middle box and an upper box which are sequentially stacked. A cavity is formed in the bottom box, the middle box and the upper box, a main pouring gate with a downward opening is arranged in the middle of the bottom box, the upper portion of the main pouring gate is connected with a bottom plate transverse pouring gate and a shape follow-up transverse pouring gate, and the shape follow-up transverse pouring gate is arranged along the bottom of the cavity; and a first vertical pouring gate and a bottom pouring gate are arranged in the middle box, the two ends of the bottom pouring gate are communicated with the cavity and the shape follow-up transverse pouring gate respectively, the lower end of the first vertical pouring gate is communicated with the bottom plate transverse pouring gate, the side face of the first vertical pouring gate is communicated with the cavity through a pouring gap, and an air hole is formed in the upper box. According to the composite casting system, the advantages of vertical cylinder gap type casting, bottom pouring type casting and differential pressure casting are combined, the feeding effect of a thick and large part at the bottom of a casting is good, and the defects of large-area looseness, shrinkage cavities and even insufficient pouring are overcome. For frame and barrel type castings with thick and large parts at the bottoms of the castings, one-time forming of the castings is guaranteed, and the quality is reliable.

Description

technical field [0001] The invention relates to the technical field of casting systems, in particular to a compound pouring system suitable for frames and cylindrical castings with thick and large parts at the bottom. Background technique [0002] The inner sprue of the bottom injection gating system is located at the bottom of the casting, the molten metal enters the cavity smoothly, the impact force on the mold and the core is small, and the oxidation of the molten metal is small, which is beneficial to the removal of gas in the cavity; the vertical gap gating system fills the mold smoothly, Through reasonable optimization of the gating system, the sequential solidification of castings can be realized; differential pressure casting technology can artificially control the filling and solidification of molten metal, and the filling of molten metal is stable, which is conducive to the removal of gas and effectively improves the mechanical properties of castings. [0003] Nowa...
