Embodiment Construction

[0032] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0033] Such as figure 1 As shown, a double-supplement interrupted anti-gravity pouring system for aluminum alloy castings according to the present invention includes a cavity, a riser 13 and a chilled iron assembly. The cavity includes several body sprues 5, and the The upper side of the cavity is provided with a number of risers 4 directly above the body sprues 5 one by one, and the lower side of the cavity is provided with a number of base plate straights directly below the body sprues 5 one by one. The runner 3, the riser 13 is located below the cavity, and communicates with several bottom sprues 3 through the bottom runner 2 respectively, and the cold iron assembly divides the cavity into several regions. The location of the vertical reinforcing rib on the aluminum alloy casting 1 is its thick and large part, and the riser 4 i...

Abstract

The invention discloses a double-compensation interruption type anti-gravity pouring system and a pouring method for an aluminum alloy casting, and belongs to the technical field of metal casting. The pouring system comprises a cavity, a riser tube and a chilling block assembly, the cavity comprises a plurality of body sprues, a plurality of risers are arranged on the upper side of the cavity and right above the body sprues in a one-to-one correspondence mode, and a plurality of bottom plate sprues are arranged on the lower side of the cavity and right below the body sprues in a one-to-one correspondence mode. The riser tube is positioned below the cavity and communicates with the plurality of bottom plate sprues through the bottom plate cross gate, and the chilling block assembly divides the cavity into a plurality of areas. And in the pouring process, bidirectional metal liquid feeding is carried out on the body sprue through a dead head and the bottom plate sprue, the defects of looseness, bubbles, slag inclusion and insufficient pouring are avoided, and the qualified rate of products is greatly increased.

Description

technical field [0001] The invention relates to a double-supplement interrupted anti-gravity pouring system and a pouring method for aluminum alloy castings, belonging to the technical field of metal casting. Background technique [0002] At present, the gating system of flat bracket castings mostly uses annular runners to connect uniform inner runners on the outside of the castings to pour them. This gating system has uniform metal liquid feeding and stable filling, and is suitable for some castings with simple structures. The rate is higher, and it has better process realizability. However, for flat bracket castings with relatively complex structures, the feeding capacity and slag discharge capacity of the ring runner system are not satisfactory. [0003] The Chinese patent document with the publication number CN104308081A discloses a method for anti-gravity pouring of aluminum alloy castings using the V method. When it is used for pouring aluminum alloy castings with fl...
