Combined type intake manifold aluminum alloy lower manifold casting blank and special mold thereof

Abstract

The invention discloses a combined type intake manifold aluminum alloy lower manifold casting blank and a special mold thereof, and belongs to the technical field of automobile engines. The problem that the weight of a casting riser end of the aluminum alloy intake lower manifold casting blank in the prior art is greater than the weight of a product end, which causes the riser end to first separate from an upper mold blank casting riser cavity, so that the product end is stuck in the mold, the ejection is unbalanced, the demolding is difficult, the product end is injured, the production efficiency is low and the rejection rate is high is overcome. The combined type intake manifold aluminum alloy lower manifold casting blank is characterized in that a first riser holding column, a second riser holding column and a third riser holding column are arranged on the blank casting riser, and a first riser holding column cavity, a second riser holding column cavity and a third riser holding column cavity are arranged on an upper mold. The combined type intake manifold aluminum alloy lower manifold casting blank has the beneficial effects that the three riser holding columns penetrate into the riser holding column cavities of the upper mold, the friction forces between the casting blank risers and the mold cavities are increased, the phenomenon that the riser end first separates from thecasting riser cavities is overcome, and the purpose of ejecting balance of the aluminum alloy lower manifold casting blank is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, in particular to a combined intake manifold aluminum alloy lower manifold casting blank made of resin material and aluminum alloy material and a special mold thereof. Background technique [0002] With the development of automobile technology and drivers' keen pursuit of vehicle handling and driving pleasure, the performance improvement of the engine and its peripheral components is becoming more and more stringent. The engine intake manifold is a key component of the engine intake system, and its main function is to provide fresh intake charge to the engine evenly. Most of the intake manifold materials in the past are made of aluminum alloy. The disadvantage of the aluminum alloy intake manifold made of aluminum alloy is that it is heavy and seriously affects the fuel consumption of the engine. After the gradual development of science and technology, resin materials have become the d...

Problems solved by technology

[0004] The problem to be solved by the present invention is to overcome the deficiencies and defects of the prior art, and to provide an aluminum alloy lower manifold that can solve the problem of the riser end in the casting production process of the combined intake manifold made of resin material and aluminum alloy material. Due to the reason of gravity, the product is demoulded first, causing the product end to be stuck in the mold, causing the problem of unbalanced ejection, thereby improving the production efficiency and yield of the aluminum alloy lower manifold blank.
