Description

Technical Field

[0001] The utility model belongs to the technical field of spraying, and in particular relates to an integrated die-casting large-scale box-type spraying device. Background Art

[0002] Large die-casting parts are formed by die casting in one step through the mold, and the workpiece has higher structural strength and better sealing. The die-casting mold is generally divided into a movable mold and a fixed mold. After each production is completed, the mold cavity of the fixed mold and the mold cavity of the movable mold need to be sprayed with a mold release agent. The existing process generally uses a manipulator to grab the nozzle to spray the fixed mold cavity and the movable mold cavity separately. Although this technical solution uses a manipulator to automatically operate, due to the complex internal structure of the mold cavity, the area required to be sprayed is large, and the spray angle range is large, resulting in a long spraying time, and it is difficult to spray evenly inside the mold cavity, affecting the production efficiency of the cylinder body. The applicant disclosed a modular mold spraying device in the patent with publication number CN218360190U, which can select the corresponding module units for assembly as needed to adapt to different mold internal structures. However, it was found in the later use of this modular mold spraying device that when it is applied to large integrated die-casting workpieces such as the above-mentioned rear frame, a large number of modules need to be added for combination, resulting in a heavy overall weight of the mold spraying device, and existing robots, robotic arms, etc. are difficult to effectively load, and there are hidden dangers during use. Then the applicant disclosed an integrated die-casting large-scale box-type spraying device and its use method in the utility model patent with application number CN202311629464.4. By combining the spray box frame and the modularly arranged spray strips, a large spraying area can be made, and nozzles and blowing nozzles that can adapt to the internal structure of the die-casting mold can be assembled at will. At the same time, the overall weight of the spraying device can be effectively controlled, so as to meet the needs of automatic internal spraying operations of large integrated die-casting die-casting molds. However, a large number of pipes still need to be connected to the inside of the spray box frame of this spray device. Due to the limited internal space of the spray box frame, it is difficult for maintenance personnel to perform corresponding operations inside the spray box frame when maintenance or addition and subtraction of nozzles are required. Therefore, it is necessary to further improve the spray device inside the mold. Utility Model Content
