Aluminum pressure casting with good pressure resistance

Abstract

The invention discloses an aluminum pressure casting with good pressure resistance. The bottom end of an aluminum pressure casting body is fixedly connected with a threaded steel pipe, the surface ofthe threaded steel pipe is sleeved with a convex nut, the convex nut is of a convex structure, the horizontal section of the convex nut is of an eccentric circle structure, and the convex nut and thethreaded steel pipe are of a threaded connection structure; the inner wall of the aluminum pressure casting body is fixedly connected with fixed blocks, and each fixed block is of a fan-shaped structure, so that the internal stress of the casting can be evenly distributed; and the bottom end of the aluminum pressure casting body is fixedly connected with a rubber ring, and the cross section of therubber ring is of a rectangular structure. The aluminum pressure casting is provided with the convex nut and a concave nut, the left side of the bottom end of the convex nut can apply transverse acting force to the right side to prevent loosening, the interior of the aluminum pressure casting body is composed of the six fixed blocks, and a fixed plate is connected between every two fixed blocks,so that internal stress distribution of the casting is more uniform, and the pressure resistance of the casting is higher.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to an aluminum die casting with good compression resistance. Background technique [0002] In daily production and life, the machinery used by people is composed of various parts through castings, and the more commonly used aluminum die castings are smelted liquid aluminum, which is poured into the pre-heated aluminum alloy by pouring, pressing or other casting methods. In the prepared mold, after cooling and subsequent processing such as grinding, the metal formed object obtained. [0003] The tensile and compressive strength of the traditional aluminum pressure fittings are relatively brittle, the structure of the casting is not stable, it is easy to cause cracks in the casting, the compression performance is poor, and the castings are connected by screws, long-term vibration will make the The screws are loose, resulting in unstable connection between the castings. The...
