Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0026] Such as Figure 1 to Figure 2 Shown, a kind of multilayer die-casting washing impregnation process of the present invention;
[0027] Assembly process: Put the multi-layer die-casting parts into the iron cage and place them in sequence according to the number of layers, cover the lid, and lock the bottom and upper parts of the iron cage with the T-shaped locking bolt 8 at the bottom and the T-shaped locking bolt 9 at the upper part;
[0028] Impregnation process: place the iron cage that has completed the assembly process in the impregnation tank filled with impregnation liquid until the die-casting product fully absorbs the impregnation liquid;
[0029] Recycling...

The invention provides a washing-infiltration technological process for multilayer laminated castings. The washing-infiltration technological process comprises the following procedures: a casting placement procedure of putting the multilayer laminated castings in an iron cage and sequentially placing the multilayer laminated castings according to a layer number, covering a lid, and locking the bottom and the top of the iron cage through a T-shaped bottom locking bolt and a T-shaped top locking bolt separately, an infiltration procedure of placing the iron cage completing the casting placementprocedure in an infiltration pool fully filled with an infiltration solution until die-casting products adequately absorb the infiltration solution, a recovery procedure of thoroughly recovering and extracting the infiltration solution in the infiltration procedure, and taking out the iron cage filled with the die castings, a washing procedure of placing the iron cage filled with the die castingsin a washing device and washing the iron cage for five to ten times, and a curing procedure of heating water in the washing device to achieve 95 DEG C and boiling the die castings in the iron cage with water.
Description
technical field [0001] The invention relates to the technical field of die casting, in particular to a water washing and impregnation process for multilayer die castings. Background technique [0002] Due to the many pores and small cracks inside the die-casting products produced by the die-casting process, the impregnation process is required to ensure the sealing of the die-casting products; however, some impregnating liquid will remain on the product after impregnation, and the traditional method is to use water to wash it. The impregnating liquid product remaining on the surface of the product, the impregnating liquid in the thread is usually difficult to clean and dissolve; and in order to improve production efficiency, multiple products are generally stacked together and impregnated intensively, so that the impregnation between products The seepage remains, and the traditional method cannot wash and dissolve it well, and the soaking solution of the traditional washing ...
