Wheel anti-gravity casting equipment with crucible heat preservation furnace

Abstract

The invention discloses wheel anti-gravity casting equipment with a crucible heat preservation furnace. The wheel anti-gravity casting equipment comprises a mold and the crucible heat preservation furnace, wherein a crucible is arranged in the crucible heat preservation furnace, a metal melt is contained in the crucible, and an electric heating device, a temperature measurement thermocouple, riserpipes on two sides and a high-pressure gas source are arranged on a furnace body; and a sprue cup and a sprue bush are connected to the upper parts of the riser pipes on the two sides, the sprue cupis in communication with the riser pipes on the two sides below, and the sprue bush corresponds to the position directly below a wheel mold rim and in communication with a cavity inlet for a pouring-in mold cavity, to deliver the rising metal melt into the cavity in a corner pouring mode. The equipment adapts to the multi-sprue side pouring mode in which a sprue is arranged directly below the wheel rim, solves the problems that a traditional large-size wheel single-riser pipe technology is poor in long-distance supplement shrink effect and the solidification temperature field is difficult to control after cooling, improves the performance and production stability of a wheel, shortens the production beat, improves the production efficiency and increases the yield of the wheel.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a wheel anti-gravity casting equipment with a crucible holding furnace. Background technique [0002] Lightweight is one of the most important ways for fuel vehicles to save energy and reduce emissions, and for new energy vehicles to reduce consumption and increase range. Replacing traditional steel materials with lightweight materials such as aluminum alloys has become an inevitable choice for vehicle design renewal. Aluminum alloys used in automobiles can be divided into cast aluminum alloys and deformed aluminum alloys. Cast aluminum alloys are mainly used to manufacture engines, clutch housings, wheels, chassis parts and other parts. With the demand for improving the quality of castings and the development of casting technology, more parts are produced by low pressure casting, differential pressure casting and pressure regulating casting, all of which are anti-gravity castin...
