Embodiment 1

[0040] Such as Figure 1-8 As shown, this embodiment provides a double-mode casting machine for casting aluminum piston blanks by lateral core pulling, including a pouring system 1, a truss picking manipulator 5, a joint pouring robot 6, a hydraulic system 7, an electrical operating system 3, and a quenching and cooling box 2, of which,

[0041]The truss pick-up manipulator 5 is set above the pouring system 1, and the joint pouring robot 6 is set on the truss pick-up manipulator 5. The joint pouring robot 6 picks up molten aluminum and pours it into the pouring system 1. A quenching cooling box 2 is set under one side of the truss pick-up manipulator 5. The truss pick-up manipulator 5 clamps the piston blank 4 poured by the pouring system to the quenching cooling box 2, the pouring system 1 is connected to the hydraulic system 7, and the hydraulic system, the truss pick-up manipulator and the joint pouring robot are all connected to the electrical operating system.

Embodiment 2

[0048] A double-mold casting machine for pouring aluminum piston blanks with lateral core pulling, the structure is as described in Embodiment 1, the difference is that the left mold 12 includes mold A34, mold B35, mold C36 and mold D34, and mold A34 and mold B are fixed Set on the outer mold base 8, the outer mold base is connected to the external mold telescopic oil cylinder through the cylindrical guide rail, the outer mold base connected to the mold A is fixed on the frame, and the mold C36 is connected to the central core telescopic oil cylinder through the central core mold base and the cylindrical guide rail. Mold D37 is connected to top mold telescopic oil cylinder 16 by cylindrical guide rail, and the pouring cavity shape after mold A34, mold B35, mold C36 and mold D34 are closed is a piston shape, and right mold 13 is identical with left mold 12 structures.

[0049] A gate 38 is set on one side of the mold D37, and the gate 38 is connected to the casting cavity throug...

Embodiment 3

[0055] A double-mode casting machine for pouring aluminum piston blanks by pulling the core horizontally. The structure is as described in Embodiment 1, the difference is that a suction device 11 is arranged on the base 18, and the suction device 11 is connected to the left mold 12 and the right mold respectively. 13. The gas generated by the heating of the salt core is absorbed by the suction device to reduce the porosity of the piston blank.

Abstract

The invention relates to a double-mold casting machine for transverse core-pulling pouring of an aluminum piston blank and a using method of the double-mold casting machine, and belongs to the technical field of piston manufacturing. The double-mold casting machine comprises a pouring system, a truss part taking mechanical arm, a joint pouring robot, a hydraulic system, an electrical operating system and a quenching cooling box, wherein the truss part taking mechanical arm is arranged above the pouring system, the joint pouring robot is arranged on the truss part taking mechanical arm, and molten aluminum is extracted by the joint pouring robot to be poured into the pouring system; and the quenching cooling box is arranged below one side of the truss part taking mechanical arm, the truss part taking mechanical arm clamps the piston blank poured by the pouring system to the quenching cooling box, the pouring system is connected to the hydraulic system, and the hydraulic system, the truss part taking mechanical arm and the joint pouring robot are all connected to the electrical operating system. Automatic operation of pouring and quenching of the piston blank is achieved, the production efficiency is improved, and meanwhile the mechanical performance and the thermal fatigue resistance of a piston are improved.

Description

technical field [0001] The invention relates to a double-mode casting machine for pouring aluminum piston blanks by transverse core pulling and a method for using the same, belonging to the technical field of piston manufacturing. Background technique [0002] As the engine explosion pressure exceeds 20MPa and the gas temperature exceeds 400°C, the high temperature and high pressure working environment has more stringent requirements on the internal combustion engine, and the improvement of the overall performance of the internal combustion engine mainly depends on the improvement of key components. The piston is the heart of the internal combustion engine. It plays a vital role in the whole engine working process and exhaust emission. [0003] At present, the piston casting machines on the market mainly include the machine body, electrical system, hydraulic system and cooling system. The pouring mode is that the operator manually pours the aluminum liquid, manually takes th...
