In addition, the appearance of the automobile part is required to be complex, and the casting molding of the product can be completed only by a plurality of sliding blocks for core pulling. Referring to fig. 1, a casting mold of such an automobile part includes a fixed mold and a movable mold; the structure of the fixed die comprises a fixed die core, upper, lower, left and right fixed die vacuum valves and a fixed die frame, and the structure of the movable die comprises upper, lower, left and right movable die slide blocks, upper, lower, left and right 4 movable die vacuum valves, a movable die core and a movable die frame. The fixed die core of the fixed die and the 4 movable die vacuum valves need to be sprayed and demoulded, but the depth of the fixed die core on the fixed die and the depth of the 4 movable die vacuum valves are different, so that the spraying difficulty is high. In addition, the core of 4 movable mould sliding blocks, the movement of 4 movable mould vacuum valves and the movable mould core of the movable mould need to be sprayed and demoulded, but the depths of the 4 movable mould sliding blocks, the movement of 4 movable mould vacuum valves and the movable mould core are different, so the difficulty of the spray head is larger.

Referring to fig. 2, regarding the spraying of a large slide casting mold for automobile parts, the prior art adopts a plurality of spray heads arranged in a matrix to perform a release agent spray head and a blowing spray head, the plurality of spray heads have the same length, and the plurality of spray heads can only be opened and closed at the same time. When the existing spraying system is adopted for spraying heads, the spraying system is driven by a manipulator to rotate around the plane where the vacuum valves (4 movable mould vacuum valves or 4 fixed mould vacuum valves) are located for one circle, the vacuum valves (4 movable mould vacuum valves in sequence or 4 fixed mould vacuum valves in sequence) are sprayed, and then the manipulator drives the spraying system to walk to the middle part to spray the fixed mould core, the 4 movable mould slide blocks, the core pulling and the movable mould core. And then spraying the mould for a plurality of times by using the travelling path, and blowing the mould by using a blowing nozzle after spraying. But it has the following problems:

1. the four-angle four-die vacuum valve is required to be sequentially sprayed by rotating the four-angle four-die vacuum valve for one circle, then the fixed die core is sprayed at the position of walking to the center, after the fixed die is sprayed, the movable die is sprayed, and the movable die is sprayed by rotating the periphery for one circle and then walking to the middle position, so that the spraying time is long, and the spraying efficiency is low;

2. in addition, all spray heads are uniformly controlled to be closed and opened, but the area of the vacuum valve is relatively large in difference with the areas of the fixed die core and the movable die core, and all vacuum valves are opened when the vacuum valve, the fixed die core and the movable die core are sprayed by the existing spraying system, so that the spraying quantity is excessive and the spraying material is wasted when the vacuum valve is sprayed; in addition, the depth of the fixed die vacuum valve is different from that of the fixed die core, and the lengths of the spray heads are equal, so that the same spraying pressure is used for spraying the coating on the spraying surfaces of the fixed die vacuum valve and the fixed die core, and the spraying is uneven;

3. secondly, the part setting of blowing is in the bottom of this system, only can blow locally, can't blow clean, influences product quality.
