Problems solved by technology

[0005] (1) The flow adjustment is not uniform, resulting in inconsistent spraying thickness on the mold surface;
[0006] (2) The flow channel is easy to block and difficult to clean;
[0007] (3) The atomization is uneven and easy to form drops;
[0009] (5) The response delay of the flow control mechanism is high, and the opening and closing are not timely;
[0010] (6), spraying and air blowing are carried out by two independent components, the cost is higher and the equipment is more complicated

Abstract

The invention discloses a multi-point separate-control spraying system. The system comprises a manipulator; a spraying material frame is arranged on the manipulator; at least two nozzles are arrangedon the spraying material frame; each nozzle comprises a coating channel and an atomizing channel; an outlet of each coating channel is connected into the corresponding atomizing channel; a pneumatic blocking piece is further arranged on each coating channel; an inlet of each coating channel is connected with a feeding part through a coating pipe; a proportional valve is arranged on each coating pipe; an inlet of each atomizing channel is connected with a high-pressure air blowing part through an air blowing pipe; an air blowing valve is arranged on each air blowing pipe; and each pneumatic blocking piece is connected with a blocking piece control part. By the aid of the system, mold coating spraying can be performed stably, the flow regulation is uniform, and the spraying thickness of thesurface of a mold is uniform; a runner is not prone to blockage, and the runner and a flow regulating valve are convenient to clean; uniform and quick atomization is realized; the spraying direction and angle can be regulated manually; a flow control mechanism is quick in response and can be opened and closed timely; and spraying and air blowing are integrated, the production cost is reduced, andthe equipment is simplified.

Description

technical field [0001] The invention relates to mold spraying, in particular to a multi-point sub-control spraying system. Background technique [0002] The die-casting process uses high pressure to hydraulically inject metal into the mold cavity, and the molten metal is cooled and solidified under pressure to form a casting. The die-casting process can manufacture metal parts with complex shapes, clear outlines, thin walls and deep cavities, and the utilization rate of materials is high. Spraying is an important link in the die-casting process. It can effectively prevent the die-casting from welding with the die-casting mold, reduce the frictional resistance when the die-casting is ejected, prevent the mold from sticking, and play a cooling role; after spraying, the mold needs to be blown dry. [0003] Since the latent heat of crystallization of magnesium alloy is smaller than that of aluminum alloy, the solidification time is faster, and it is more sensitive to the mold ...
