Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all involve the protection scope of the present invention.

[0041] Such as Figure 1 to Figure 12 As shown, this embodiment proposes a novel sprue bushing for centrifugal casting aluminum, including:

[0042] Sprue sleeve body 1;

[0043] The first filter screen 2 is set in the sprue sleeve body 1 and is used to filter impurities in the aluminum water. The cross section of the first filter screen 2 is perpendicular to the axis of the sprue sleeve body 1;

[0044] The deflectors 3 are multiple and are all arranged on the bottom surf...

Abstract

The invention relates to the technical field of centrifugal casting, and proposes a novel sprue bushing for centrifugal casting aluminum, which includes a sprue bushing body; The axes are perpendicular to each other; the deflector is set on the bottom surface of the first filter net, and the mesh of the deflector and the first filter net are misplaced; the connecting self-locking component is set on the sprue sleeve body to connect the sprue sleeve body In the feeding pipe of the sand box; the opening and closing assembly is arranged at the opening of the sprue sleeve body and includes a rotating shaft, a baffle and a coil spring. The body of the sprue sleeve is rotatably connected, and the coil spring is arranged on the body of the sprue sleeve. Through the above technical solution, the problem in the related art that the opening size of the sprue sleeve cannot be changed is solved.

Description

technical field [0001] The invention relates to the technical field of centrifugal casting, in particular to a novel sprue sleeve for centrifugal casting aluminum. Background technique [0002] Centrifugal casting is a method of pouring molten metal into a high-speed rotating cavity and solidifying under the action of centrifugal force to obtain castings. It is often used to manufacture sleeve-type composite metal castings. In conventional centrifugal casting methods, the filling of the cavity of the hollow mold is based on the rotation of the hollow mold about a rotational axis. Due to this rotational action, a corresponding centrifugal force acts on the liquid molten casting material during pouring, thereby pressing the casting material into the mold cavity and ensuring complete filling. During the use of the centrifugal aluminum casting site, the high-temperature aluminum water enters the sprue sleeve, but the flow rate of the aluminum water will change with the capacity...
