Die-casting pouring method for left engine mounting bracket and mold thereof

Abstract

The invention discloses a die-casting pouring method for a left engine mounting bracket. The die-casting pouring method comprises the following steps that (1), a mold is installed to a die-casting machine; (2) molten aluminum is poured into a molten cup tube in the mold; (3) the molten aluminum in the molten cup tube is pressed to a pouring gate in the mold at a low speed through a runner via a hammer of the die-casting machine; (4) the hammer is pressed forwards at a high speed, so that the molten aluminum in the molten cup tube is pressed into a mold cavity and a cinder ladle; (5) pressurization is performed through the hammer, so that the product in the mold cavity is solidified; (6) the die-casting machine is turned on to de-molding the product; (7) the cinder ladle and the runner on the product are removed. The die-casting pouring method has the advantages that the process is stable, production speed is high, and yield is high; by the adoption of the method for the production of the left engine mounting bracket, product quality is guaranteed, product weight is reduced, and meanwhile the oil consumption of the whole vehicle is lowered; besides, production cost is also lowered.

Description

technical field [0001] The invention relates to a die-casting pouring method and a mold thereof, in particular to a die-casting pouring method and a mold thereof for an engine left suspension bracket. Background technique [0002] At present, the existing left engine mount bracket is produced by casting. Although this method can produce the product, the method still has the following deficiencies: 1. Since the left engine mount is produced by the casting method The process of the bracket is unstable, resulting in the quality of the product cannot be guaranteed. At the same time, the process makes the production speed slower, which directly affects the yield; 2. The left engine mount bracket produced by this casting method has a high cost; 3. Because the method uses molten iron for casting, the quality of the product is relatively heavy. After being installed on the automobile, the overall weight of the automobile is increased, and the fuel consumption of the automobile i...

Since the left engine mount is produced by the casting method The process of the bracket is unstable, resulting in the quality of the product cannot be guaranteed. At the same time, the process makes the production speed slower, which directly affects the yield; 2. The left engine mount bracket produced by this casting method has a high cost; 3. Because this method uses molten iron for casting, the quality of the product is relatively heavy. After being installed on the car, the overall weight of the car is increased, and the fuel consumption of the car is improved.
