Embodiment 1

[0042] Such as Figure 1-7 As shown, this embodiment provides a single-mode casting machine for pouring aluminum piston blanks by tilting 90°, including a frame 1, a workbench 2, a tilting cylinder 10, a pouring system 5, a hydraulic system 3 and an electrical system 4, wherein , a workbench 2 is set on the frame 1, and a pouring system 5 is set on the workbench 2, and the piston blank is poured by passing aluminum liquid into the pouring system 5, and tilting cylinders 10 are respectively set on both sides of the bottom of the frame 1, and the tilting cylinders The other end of 10 is connected to the workbench 2, the tilting cylinder 10 and the pouring system 5 are both connected to the hydraulic system 3, and the hydraulic system 3 is connected to the electrical system 4.

[0043] The workbench 2 includes an upper base plate and a lower base plate, the upper base plate and the lower base plate are connected by four columns 8, the two sides of the lower base plate are connect...

Embodiment 2

[0061] A single-mode casting machine for pouring aluminum piston blanks with a tilt of 90°. The structure is as described in Embodiment 1. The difference is that temperature sensors are respectively set on the upper tooling, lower tooling, left tooling and right tooling, and the temperature sensors are connected to The electrical system detects the pouring temperature through the temperature sensor, and gives an alarm when the temperature is not up to standard, so as to ensure the solidified grain structure of the piston blank.

Embodiment 3

[0063] A single-mode casting machine for pouring aluminum piston blanks by tilting 90°, the structure is as described in Embodiment 1, the difference is that a suction device 6 is arranged on the frame 1, and the suction device 6 is connected to a salt core support rod 18 , absorb the gas generated by the heating of the salt core through the suction device, and reduce the porosity of the piston blank.

Abstract

The invention relates to a single-mold casting machine capable of tilting at 90 degrees to form aluminum piston workblanks through pouring and a use method of the single-mold casting machine capable of tilting at 90 degrees to form the aluminum piston workblanks through pouring. The casting machine comprises a rack, a workbench, tilting oil cylinders, a pouring system, a hydraulic system and an electric system, wherein the workbench is arranged on the rack, the pouring system is arranged on the workbench, aluminum liquid is introduced into the pouring system to form the piston workblanks through pouring, the tilting oil cylinders are arranged at two sides of the bottom of the rack respectively, the other end of each tilting oil cylinder is connected with the workbench, the tilting oil cylinders and the pouring system are all connected with the hydraulic system, and the hydraulic system is connected with the electric system. According to the single-mold casting machine capable of tilting at 90 degrees to form the aluminum piston workblanks through pouring and the use method of the single-mold casting machine capable of tilting at 90 degrees to form the aluminum piston workblanks through pouring, the single-mold casting machine capable of tilting at 90 degrees to form the aluminum piston workblanks through pouring tilts at 90 degrees to form the piston workblanks through pouring, thus the aluminum liquid is subjected to inertia pouring under the action of gravity, a pouring cavity is filled with the aluminum liquid from bottom to top, thus air gap effects of flat pouring are avoided, and meanwhile, feeding positions of the piston workblanks are adjusted to side surfaces, so that effects on the performance of a piston combustion chamber are avoided, and the mechanical performance and the thermal fatigue resistance performance of the piston workblanks are improved.

Description

technical field [0001] The invention relates to a single-mode casting machine for pouring aluminum piston blanks by tilting 90° and a method for using the same, belonging to the technical field of piston casting. Background technique [0002] At present, the aluminum piston blank casting machine mainly used in the market includes the machine body, electrical system, hydraulic system and cooling system. The piston blank cast by the machine is a vertical structure, that is, the head is on the top and the skirt is on the bottom, but the cast blank piston head There will be a thick feeding port on the top surface of the combustion chamber, and it is difficult to achieve rapid cooling after forming. This will result in coarse grain structure, poor metallographic structure, and prone to pores and sand holes. After installation, the piston has to withstand high temperature and high temperature. Burst pressure, poor metallographic structure and pores and sand holes will affect the m...
