Problems solved by technology

[0003] At present, when pouring aluminum pistons, it is easy to cause bubbles in the aluminum water due to the difference in the flow rate when pouring aluminum water, which will lead to air bubbles in the piston after casting, and air bubbles in the piston will affect the hardness and service life of the piston.

Abstract

The invention discloses a pouring mold for an aluminum piston. The pouring mold comprises an upper mold plate and a lower mold plate, wherein a pouring pipe is arranged at the top of the upper mold plate, a slurry storage barrel is fixedly connected to the inner surface of the pouring pipe, a top cover is coupled to the top of the slurry storage barrel, and a flow blocking assembly is arranged in the slurry storage barrel. By arranging the slurry storage barrel to store molten aluminum, a top cover and a baffle plate on a rotating rod are matched to seal the slurry storage barrel, and gas is then injected into the slurry storage barrel through a spring pipe on an inflator pump, so that the internal pressure can be increased; the flow blocking assembly is opened, molten aluminum can flow down uniformly under the action of gravity and pressure, and meanwhile, by controlling the inflation speed of the inflator pump, the flowing speed of the molten aluminum can be controlled, so that the possibility of generating bubbles during pouring can be reduced as much as possible.

Description

technical field [0001] The invention relates to the technical field of aluminum pistons, in particular to a casting mold for aluminum pistons. Background technique [0002] A mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. With the increasing development of the machinery manufacturing industry, such as the continuous improvement of the engine piston manufacturing technology, the mold is an important process equipment for casting aluminum pistons when producing pistons. The method of pouring in the mold. [0003] At present, when pouring aluminum pistons, it is easy to cause bubbles in the aluminum water due to the difference in the flow rate when pouring the aluminum water, which will lead to bubbles in the piston after casting, and the bubbles in the piston wil...
