Problems solved by technology

[0003] In order to make up for the shortcomings of the existing technology, most of the production process in the piston casting industry adopts traditional manual casting or semi-automatic casting. In the entire production process, a large amount of work needs to be done manually, which is dangerous, labor-intensive, and energy-consuming. 1. The utilization rate of aluminum water is low, the production efficiency is low, and the consistency and stability of product quality cannot be effectively controlled. At the same time, the piston will splash aluminum water when the casting equipment pours aluminum water during the casting process, resulting in waste of aluminum water and safety. Hidden danger problem, a kind of piston automatic casting process that the present invention proposes

Embodiment approach

[0032] As an embodiment of the present invention, the wedge 17 is an upwardly protruding arc structure, and the arc wedge 17 reduces the impact on the movement of the casting trolley 13, and reduces the overflow of aluminum water from the aluminum pool 2; through the arc The wedge 17 makes the casting trolley 13 slowly and steadily push the wedge 17 and the ejector rod 16 to move downward during the movement, thereby reducing the impact of the wedge 17 on the speed of the casting trolley 13, reducing the sudden change in the speed of the casting trolley 13, and reducing the aluminum The overflow of the aluminum water in the pool 2 further increases the utilization rate of the aluminum water and increases the casting efficiency of the piston.

[0033] As an embodiment of the present invention, the communication hole 22 is lower than the liquid level of the aluminum water in the aluminum water pool 2; a chute 23 is provided at a position corresponding to the communication hole 22...

Abstract

The invention belongs to the technical field of piston casting, and specifically relates to a piston automatic casting process. The casting device used in the casting process includes a mold; the bottom of the mold is hinged to the workbench; There is a transfer platform on the casting trolley, and the transfer platform is hinged with the casting trolley; there is an aluminum pool on the transfer platform, and a casting nozzle is arranged on the top of the aluminum pool, and the casting nozzle is connected with the aluminum pool through a communication hole; the side of the aluminum pool away from the mold is provided with The cylinder is arranged obliquely, one end of the cylinder is hinged with the aluminum pool, and the other end is hinged with the casting trolley; there is an L-shaped ejector rod slidingly connected under the slide rail, and the ejector rod slides in the vertical direction; a wedge is provided on the top of the ejector rod, and the bottom of the casting trolley A top block is provided at the position corresponding to the wedge block; the invention uses the top block to push the wedge block, and the mold is tilted by the transmission of the ejector rod, so as to reduce the spilling of aluminum water during pouring into the casting riser, and increase the casting efficiency of the piston.

Description

technical field [0001] The invention belongs to the technical field of piston casting, in particular to a piston automatic casting process. Background technique [0002] The piston is a reciprocating part in the cylinder block of an automobile engine. It forms a piston group with piston rings, piston pins and other parts, and forms a combustion chamber with the cylinder head. It bears the force of gas and transmits power through piston pins and connecting rods. To the crankshaft to complete the working process of the internal combustion engine. At present, the pistons of modern engines are generally cast from aluminum alloy. Most of the production process in the piston casting industry adopts traditional manual casting or semi-automatic casting. There is a lot of work that needs to be done manually in the entire production process, which is dangerous and labor-intensive. High, high energy consumption, low utilization rate of aluminum water, low production efficiency, and th...
