Description

Technical Field

[0001] This utility model relates to the field of mold cleaning technology, specifically to a dust removal device for the inner surface of a casting mold. Background Technology

[0002] Casting molds are core tools in metal casting processes, used to form precise cavities for castings. They are typically made of steel, cast iron, or aluminum alloys and must possess high temperature resistance, high strength, and wear resistance. Mold design must consider parameters such as shrinkage rate and draft angle to ensure dimensional accuracy of the castings. Based on the process, they can be divided into sand molds and metal molds, the latter mostly used for mass production. Dust removal from the inner surface of casting molds directly affects casting quality and production efficiency. Residual dust can lead to defects such as rough surface, porosity, and inclusions in the castings, affecting dimensional accuracy. Traditional methods of dust removal from the inner surface of casting molds involve workers using a handheld high-pressure gas spray gun to spray high-pressure air onto the inner surface of the mold. This method generates a large amount of dust in the workspace during mold cleaning, polluting the air within the work area. Utility Model Content

[0003] The purpose of this utility model is to provide a dust removal device for the inner surface of casting molds, in order to solve the problem mentioned in the background art that the traditional method of dust removal for the inner surface of casting molds involves workers holding a high-pressure gas spray gun and spraying high-pressure airflow onto the inner surface of the casting mold to treat the dust adhering to the inner surface of the casting mold. This method results in a large amount of dust being generated in the work space when cleaning the mold, causing air pollution in the work space.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for the inner surface of a casting mold, comprising a body, the upper end of which is connected to a cover via a hinge, the lower end of which is open, a partition at the upper interior of the body, a sealing ring at the middle of the partition, a collection hood at the lower end of the partition, a load-bearing frame between the front and rear sides of the collection hood and below the sealing ring, a dust collection channel connected to the lower end of the collection hood, a dust collection box at the lower end of the dust collection channel, a suction pipe connected to one side of the dust collection channel, a filter end at one end of the suction pipe inside the dust collection channel, and air jet pipes penetrating the inner sides of all four sides of the collection hood, with air supply pipes connecting the input ends of the four air jet pipes.

[0005] Preferably, an annular diversion pipe is provided on the outer side of the collection hood and between the lower ends of the four jet pipes. The gas supply pipe is connected to one side of the annular diversion pipe. A connecting seat is provided on the inner side of the annular diversion pipe at the position corresponding to the four jet pipes. The four jet pipes are respectively fixedly connected to the four connecting seats by threads. A nozzle is provided at the upper end of each of the four jet pipes.

[0006] Preferably, the collection hood is a hollow trapezoidal structure, the dust collection channel is a cuboid structure with dimensions corresponding to the smaller side of the trapezoidal surface of the collection hood, and the dust collection box is a cylindrical structure connected to the lower wall of the dust collection channel by threads.

[0007] Preferably, the outer end of the suction pipe is connected to a suction fan, and the output end of the suction fan extends to the outside of the machine body.

[0008] Preferably, a through groove is provided at the middle position of the lower end of each of the four side walls of the machine body.

[0009] Compared with the prior art, the beneficial effects of this utility model are: it replaces the traditional method of cleaning the inner surface of the casting mold by having workers hold a high-pressure gas spray gun to clean the inner surface of the casting mold, and maintains the method of treating the dust attached to the inner surface of the casting mold by high-pressure airflow. Through the overall structural design of the dust removal device, dust is avoided in the work space when cleaning the mold, thus avoiding pollution of the air in the work space.
