Technical Field

The invention belongs to the technical field of die-casting spraying, and particularly relates to an integrated die-casting large-scale box-type spraying device and a using method thereof.

Background

The large die casting is formed by one-step die casting through the die, and the workpiece has higher structural strength and better tightness. The die casting mold is generally divided into a movable mold and a fixed mold, the fixed mold is fixed, and the movable mold is driven by a driving mechanism to perform mold closing or mold opening. After each production is completed, the mold release agent needs to be sprayed to the fixed mold cavity and the movable mold cavity, the prior art generally sprays the fixed mold cavity and the movable mold cavity respectively through the operation of a manipulator grabbing spray head, and the technical scheme adopts the automatic operation of the manipulator, but because the internal structure of the mold cavity is complex, the spraying area is large, the spraying angle range is large, the spraying time is long, the inside of the mold cavity is difficult to spray uniformly, and the production efficiency of the cylinder body is influenced. For example, the rear frame of an automobile is formed by adopting secondary processing such as sectional die casting, welding, screw connection and the like. The prior art adopts an integrated die-casting process, can be molded in sequence, improves the processing efficiency and the structural strength of the frame, and reduces the cost. However, when the die for one-time die casting is in spraying operation, the areas needing to be sprayed respectively are more because of large inner area of the die, and the existing spraying device is difficult to meet the requirement of high-efficiency flow line production. Applicant discloses in the patent of publication number CN218360190U a modular in-mold spray device that can be assembled by selecting the corresponding modular units as required to accommodate different mold internals. The spray device is disassembled and reassembled after die changing to form a shape matched with the inner structure of the new die, and the nozzle is arranged at the corresponding position, so that only a small number of parts are required to be processed during reassembling, and idle waste of the spray device after die changing is avoided. However, the in-mold spraying device is found in the later use process, when the in-mold spraying device is applied to large-scale integrated die-casting formed workpieces such as the rear frame, a large number of modules are required to be added for combination, so that the whole weight of the in-mold spraying device is heavy, the existing robots, mechanical arms and other difficult and easy effective loads have hidden dangers in the use process. Accordingly, there is a need for further improvements to the in-mold spray device.
