Abstract

The invention provides an integrative sprue cup for aluminum alloy casting and a manufacturing method. According to the integrative sprue cup, a lower socket and a lower sprue are formed in the lower part of a cup body; a rotating handle is arranged at the upper part of the cup body; an upper socket is formed in the cup body wall of the upper part of the rotating handle; an upper sprue is formed in the upper part of an inner cavity of the cup body; a shoulder is arranged on the cup body wall of the lower part of the upper sprue; a filter piece is placed on the shoulder to form the integrative sprue cup. The integrative sprue cup is manufactured through the steps of raw material preparing, raw material compounding and integrative sprue cup manufacturing. The integrative sprue cup manufactured by adopting the manufacturing method has the characteristics of being high-temperature resistant, corrosion-resistant, thermal-shock resistant, slagging-free, fatigue-resistant, free from sticking to aluminum, good in air tightness, long in service life and suitable for the application of manufacturing the integrative sprue cup for aluminium alloy casting.

Description

technical field [0001] The invention provides a component used in the casting field, in particular a method for manufacturing an integrated sprue cup for aluminum alloy casting. Background technique [0002] Aluminum alloy casting must use a sprue cup to inject aluminum alloy liquid into the mold. The existing sprue cup usually adopts a two-body plug-in structure, so there is a problem of liquid leakage at the interface, and it is inconvenient to use. Contents of the invention [0003] In order to integrate the sprue cup, the present invention proposes a method for manufacturing an integrated sprue cup for aluminum alloy casting. In the method, the integrated sprue cup is produced through the steps of raw material preparation, raw material batching and integrated sprue cup manufacturing. Solve the technical problems of the structure and manufacture of the integrated sprue cup. [0004] The scheme that the present invention solves technical problem adopts is: [0005] In...
