Abstract

The invention discloses a large aluminum-magnesium alloy vibration reduction device casting system which comprises a first vibration reducer cavity, a second vibration reducer cavity and a casting system body. The first vibration reducer cavity and the second vibration reducer cavity have a same structure; the casting system body comprises a filter, a straight pouring gate, a first transverse pouring gate, a first straight-edge inner pouring gate, a first arc-edge inner pouring gate, a second transverse pouring gate, a second straight-edge inner pouring gate and a second arc-edge inner pouring gate; one end of the first arc-edge inner pouring gate is connected with the first transverse pouring gate, the other end of the first arc-edge inner pouring gate communicates with an arc-edge cavity wall of the first vibration reducer cavity, one end of the second arc-edge inner pouring gate is connected with the second transverse pouring gate, and the other end of the second arc-edge inner pouring gate communicates with an arc-edge cavity wall of the second vibration reducer cavity. According to the large aluminum-magnesium alloy vibration reduction device casting system, two castings are adopted to be symmetrically cast and share one casting system, therefore, technological waste generated by at least one straight pouring gate is reduced, and the molding sand using amount is at least decreased by half.

Description

technical field [0001] The invention relates to the technical field of casting large-scale aluminum-magnesium alloy castings, in particular to a casting system and a casting method for a large-scale aluminum-magnesium alloy vibration damping device. Background technique [0002] The anti-serpentine shock absorber seat is a device used to control serpentine motion on rail vehicles, and has guiding and vibration-damping effects on the operation of rail vehicles. The anti-serpentine shock absorber seat is a stressed part, which requires high density and good mechanical properties. However, due to the existence of a large hot spot with a thickness of 110mm, loose defects are prone to occur during the casting and solidification process. [0003] Traditional gravity casting systems and casting methods mostly use single-piece castings. During single-piece casting, the waste of molding sand is serious, the yield rate of the process is low, and the casting cost is high, and the dens...
