Abstract

The invention discloses a method for manufacturing an aluminum alloy casting of an electronically controlled sliding door for a high-speed train and the casting. Temperature field wall thickness; metal type low-pressure mold preparation, when preheating the mold, heat the metal type low-pressure mold in different regions, and the temperature gradually decreases from the bottom to the top from the feed inlet to create a stable field of sequential solidification; spray paint When the paint thickness is from bottom to top, the order is from thick to thin, and the heat preservation is from top to bottom, from strong to weak; determine the aluminum alloy composition, Si6.5‑7.0%, Mg0.30‑0.40%, Ti0.13 ‑0.18%, Fe≤0.19%, Cu≤0.1%, Mn≤0.1%, Zn≤0.1%, other impurities≤0.1%, others are Al; low-pressure casting, low-pressure casting according to the preset low-pressure casting process parameters; casting Heat treatment, heat treatment of castings after pouring. The casting made by the aluminum alloy casting of the electronically controlled sliding door of the high-speed train provided by the invention has low cost and good quality.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting, in particular to a method for manufacturing an aluminum alloy casting of an electronically controlled sliding door of a high-speed train and the casting. Background technique [0002] With the rapid development of the world economy and the deteriorating global energy and environmental problems, in the face of increasingly serious traffic congestion, high-speed trains are fast, large-capacity, low-energy consumption, low-emission, popular, safe, comfortable, and environmentally friendly travel transportation Tools are evolving at a rapid pace. [0003] Passenger trains have undergone 6 major speed increases successively. The speed of motor trains has ranged from 250 to 350 to the current 380. In the next few years, high-speed trains will develop rapidly. In order to improve the safety and comfort of trains, it is necessary to carry out maintenance on the doors of trains. keep impro...
