Full-automatic casting equipment for aluminum pistons of gasoline engines

Abstract

The invention provides full-automatic casting equipment for aluminum pistons of gasoline engines. The full-automatic casting equipment comprises at least two main casting machines; and each main casting machine comprises a bed body support, a bed body mounted on the bed body support, a central core mechanism, a slewing mechanism, an outer mold mechanism, a top mold mechanism and a casting taking,casting and quenching manipulator. The full-automatic casting equipment for the aluminum pistons of the gasoline engines further comprises at least two filtering net conveying devices, at least two casting and quenching mechanisms, at least two molten aluminum temperature holding furnaces, a pouring robot and a hydraulic station; each filtering net conveying device is connected with one side of the corresponding main casting machine; each casting and quenching mechanism is connected with the other side of the corresponding main casting machine and is opposite to the corresponding filtering netconveying device; the molten aluminum temperature holding furnaces are adjacent to the main casting machines; the pouring robot is arranged between the two main casting machines and is adjacent to the molten aluminum temperature holding furnaces; and the hydraulic station is adjacent to the filtering net conveying devices. According to the technical scheme, full-automatic casting of four molds inone machine is realized, the production efficiency is high, the production cost is reduced, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of casting production line equipment, in particular to a fully automatic casting equipment for aluminum pistons of gasoline engines. Background technique [0002] With the strict control of engine emission requirements and the improvement of the strengthening degree, major automobile companies and engine factories continue to increase the engine's burst pressure and liter power in design, and ordinary aluminum pistons are increasingly unable to meet the growing design requirements. Under this background, high-strength materials and lightweight aluminum pistons were produced. [0003] Lightweight aluminum piston refers to the use of new high-strength aluminum alloy materials in the design and manufacture of pistons, and the design of weight reduction chambers on the basis of traditional pistons to reduce weight while ensuring quality. [0004] At present, this kind of piston is becoming more and more common ...

AI Technical Summary

Problems solved by technology

[0004] At present, this kind of piston is becoming more and more common with the development of the automobile industry, and the demand is extremely high. However, the commonly used production method is the production mode of manual mold casting, which has low production efficiency and low yield.

[0005] In related technologies, some companies use a two-mold casting machine for aluminum pistons. This casting machine adopts the method of manual pouring, manipulators take the blanks, and one casting to produce two piston blanks. The following technical defects exist: (1) Casting process action It is done manually by the operator. Due to the heavy aluminum liquid, the operation time is long, the labor intensity of the workers is high, the equipment cycle is long, the equipment is one machine with two molds, and the production efficiency is low.

(2) The pouring is manual pouring, which is greatly affected by human factors, the weight of molten aluminum cannot be stably controlled, the pouring speed is fast and slow, the product size is unstable, and the quality is unstable

(3) Two people are required to cooperate to operate the equipment, the labor cost per unit output is high, one machine has two models, the efficiency is low, the manufacturing cost is expensive, the follow-up processing allowance is large, and the cost is high
