Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, and in particular relates to a contour spraying fixture. Background Technology

[0002] In the aluminum alloy die-casting production process, in order to facilitate demolding and improve product quality, a release agent needs to be sprayed onto the mold surface and then dried by air blowing before die casting. Traditional spraying fixtures mostly adopt a decentralized layout, that is, the valve groups, distribution blocks, and nozzle brackets that control the air and liquid circuits are installed separately.

[0003] The existing split structure has the following drawbacks: First, the functional modules are scattered, resulting in a loose overall structure, large space occupation, low integration, and inconvenience for installation and maintenance in space-constrained die-casting machines; second, the numerous external hose connection interfaces not only increase assembly time and complexity, but also increase the risk of leakage due to too many joints, so it is urgent to improve it. Utility Model Content

[0004] The purpose of this utility model is to solve the aforementioned technical problems existing in the prior art and to provide a contour spraying fixture. This spraying fixture improves the integration of the fixture by integrating the fixed mold air control valve group, the moving mold air control valve group, the air blowing pipeline connector, and the release agent pipeline connector onto the mounting main board. It overcomes the shortcomings of the prior art, such as scattered components and redundant pipelines, resulting in a compact and reasonable overall layout. This significantly reduces the number of external connection pipelines and connectors, not only reducing the risk of leakage and improving system reliability, but also facilitating the reduction of the device size, making it easier to install and arrange in the narrow space of a die-casting machine. It also facilitates centralized maintenance and troubleshooting in the later stages.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A contour spraying fixture includes a connecting unit, a control unit, and a spraying unit. The connecting unit is connected to the control unit, the control unit is mounted on the spraying unit and communicates with the spraying unit, and the spraying unit is equipped with a plurality of release agent nozzles and air blowing nozzles. The control unit includes a main board that is mounted on the spraying unit. The main board is equipped with a fixed mold pneumatic valve group and a moving mold pneumatic valve group. The fixed mold pneumatic valve group and the moving mold pneumatic valve group are equipped with air blowing pipe connectors that are connected to air blowing nozzles. The main board is also equipped with a release agent pipe connector that is connected to a release agent nozzle.

[0006] This spraying fixture improves the integration of the fixed mold air control valve group, moving mold air control valve group, air blowing pipeline connector, and release agent pipeline connector onto the mounting main board.

This significantly reduces the number of external connection pipes and connectors, lowering the risk of leakage, improving system reliability, and reducing the size of the device. This makes it easier to install and arrange in the confined space of a die-casting machine, while also facilitating centralized maintenance and troubleshooting in the future.

[0007] Furthermore, the fixed mold air control valve group and the moving mold air control valve group are equipped with quick-release connectors, and the quick-release connectors are equipped with exhaust valves to remove residual gas in the air circuit.
