Description

Technical Field

[0001] The utility model relates to the technical field of mold parts processing, in particular to a pickling device for automobile mold parts processing. Background Art

[0002] As an indispensable part of automobile manufacturing, the accuracy and reliability of molds directly affect the final quality of parts. The progress of mold manufacturing technology has become a key component of modern manufacturing technology, covering the essence of many modern manufacturing technologies. In the mold manufacturing process, the material selection of mold accessories is particularly important, such as tungsten steel, high-speed steel, bearing steel, stainless steel, brass, metal alloys, spring steel, carburized steel, etc. These materials ensure the high strength, high wear resistance and long life of the mold. However, after the mold parts are processed, impurities such as black skin and oxides are often attached to their surface, making the surface of the parts appear dull and gray. In order to improve the performance of mold parts, pickling treatment has become an indispensable process. Pickling can effectively remove impurities on the surface of mold parts and improve their surface finish and overall performance.

[0003] However, the pickling equipment used in the existing mold parts processing process has certain limitations. Since a large number of parts are placed in the pickling equipment for processing at the same time, the mutual contact between the parts makes it difficult for many contact surfaces to fully contact with the pickling liquid, thus affecting the pickling effect; in addition, the relative static state between the parts and the pickling liquid also makes it difficult for the corrosion products on the outer wall of the parts to be effectively peeled off. These corrosion products adhere to the outer wall of the parts, hindering the acid from deeply cleaning the parts, further reducing the pickling efficiency; more seriously, there are often many small gaps in the mold parts, which are difficult to be thoroughly cleaned by conventional pickling methods. In order to ensure the overall cleanliness of the parts, the staff have to clean them manually. However, the acidic harmful substances contained in the pickling liquid are in contact with the skin for a long time, posing a serious threat to the health of the staff's hands, and there are safety hazards that cannot be ignored.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 6 To achieve the above purpose, the utility model provides the following technical solutions:

By placing the mold parts to be pickled on the parts holder 3, the parts are ensured to be stable and evenly distributed; the liquid pump starts to work, and the pickling liquid in the liquid storage tank 8 is pumped into the pickling tank 1 through the discharge pipe 10. The pickling liquid flows into the pickling tank 1 through the liquid outlet at the top of the protective cover 2 and is sprayed on the mold parts. The pickling liquid contacts the surface of the mold parts and begins to remove the oxide layer, rust and other impurities on the surface; the worm gear reducer 7 drives the rotating shaft 5 at one end of the parts holder 3 to rotate through the coupling, thereby driving the entire parts holder 3 to rotate in the pickling tank 1. This rotation method ensures that the mold parts can be evenly pickled. Local over-pickling or under-pickling is avoided; during the pickling process, the waste liquid (i.e., a mixture containing impurities and reacted pickling liquid) will flow into the waste liquid recovery tank 4, wherein the design of the waste liquid recovery tank 4 enables the waste liquid to be stored in a centralized manner for subsequent treatment and discharge; when the oxide layer, rust, etc. on the surface of the mold parts are completely removed and the expected pickling effect is achieved, the liquid pump is turned off, the inflow of the pickling liquid is stopped, the protective cover 2 is opened, and the mold parts that have been pickled are taken out for subsequent treatment or storage; the pickling box 1 and the waste liquid recovery tank 4 are cleaned to remove the residual waste liquid and impurities to ensure the normal operation of the equipment when it is used next time.

[0026] Please refer to Figure 4 , Figure 5 As an embodiment of the utility model, a plurality of fixing clamps 9 are respectively provided on the two long sides of the part fixing frame 3, wherein a hollow mesh plate 11 is provided at the bottom of the part fixing frame 3; the fixing clamps 9 include a fixing seat 901, wherein the fixing seat 901 is fixedly connected to the outer wall of the part fixing frame 3; a handle 902 is provided on the fixing seat 901, wherein the handle 902 is movably connected to the fixing seat 901; a sliding sleeve 903 is provided on the fixing seat 901, wherein a movable rod 904 is provided inside the sliding sleeve 903; one end of the movable rod 904 is hinged to the handle 902 through a curved arm 905, wherein the other end of the movable rod 904 passes through the side wall of the part fixing frame 3, and is fixedly connected to a rubber clamp 906.

In order to ensure that the waste gas can be smoothly and completely transported to the waste gas adsorption box 19, the exhaust pipe 18 and the air outlet of the exhaust fan 17 and the inlet of the waste gas adsorption box 19 need to maintain a sealed connection; the waste gas adsorption box 19 is a device for treating harmful gases discharged from the pickling box 1, wherein the waste gas adsorption box 19 is usually filled with activated carbon or other adsorption materials, which can effectively adsorb and remove harmful substances in the waste gas; the exhaust fan 17 is installed at the top of the protective cover 2 to ensure that the gas inside the protective cover 2 can be directly extracted; during the pickling process, harmful gases, such as acidic gases or volatile organic compounds, will be generated. The exhaust fan 17 can effectively extract these harmful gases from the protective cover 2, which helps to keep the pickling environment clean and reduce the harm of harmful gases to the surrounding environment and operators. At the same time, the operation of the exhaust fan 17 can also prevent the steam or mist generated by the pickling process from accumulating inside, affecting the pickling effect and working environment.
