The invention discloses a precision casting for an agricultural harvesting and bundling machine in the technical field of precision casting processing. A mold adopted by the precision casting comprises an upper template mold and a lower template mold, and the upper template mold comprises an upper moulding flask and an upper sand mold in the moulding flask, and two sprue gates and two risers are formed in the upper sand mold. The process of the precision casting comprises the following steps that S1, a mold process design; S2, feeding inspection; S3, sand mold preparation and molding; S4, smelting and cleaning; S5, simulation machining design; and S7, casting machining. The situation that sand is attached to the surface of the casting can be reduced, and deslagging agents are added into molten metal before pouring; a slag collecting bag and a slag blocking device are arranged at the sprue gates, and the situation of slag inclusion can be effectively reduced; the internal and external defects of the casting can be detected, and the internal and external defects of a product can be effectively detected; and the casting quality is further guaranteed, and the use performance is improved.
Description
technical field [0001] The invention relates to the technical field of precision casting processing, in particular to precision castings for agricultural harvesting and bundling machines. Background technique [0002] As a big country in casting production, my country's casting output has ranked first in the world for many years, accounting for more than 40% of the global total output. In recent years, my country's large-scale foundry enterprises have generally invested heavily in foundry equipment in the process of new project construction and technological transformation, and even the overall equipment level of a few domestic large-scale foundry enterprises has reached the level of foreign industrially developed countries. With the improvement of technology and equipment level of my country's foundry enterprises, the quality of my country's casting products has steadily improved. The dimensional accuracy, surface quality and internal quality of some castings have reached t...
