The invention discloses a preparation method of a precoated sand modeling and core making casting motorcycle steering column connecting plate. The preparation method comprises the following steps thatS1, a casting drawing is drawn; S2, a mold is manufactured, and a steel mold of a product is manufactured according to the casting drawing; S3, models are manufactured through sand injection, and after precoated sand is injected into the heating steel mold through air pressure, the models are taken out after pressure maintaining and heating; S4, model combining is carried out, wherein the taken-out upper model and lower model are combined together; S5, model pressing is carried out, wherein the mold obtained after model combining is placed in a casting area and then is inserted into a castingcup and a riser cup, and finally the models are pressed by an iron block; S6, casting is carried out, wherein molten iron obtained after melting is poured into the mold in mould assembling to achievecasting; S7, clearing is carried out, wherein sand on a casting after forming is cleared away; and S8, heat treatment is carried out, wherein the formed casting is subjected to annealing treatment. The method has the beneficial effects that the traditional motorcycle steering column casting technology is simplified, product quality is improved, production cost is reduced, the technological process is optimized, and the method is suitable for large-batch production.
Description
technical field [0001] The invention relates to the field of casting technology, in particular to a method for preparing a motorcycle steering column connecting plate for core casting with coated sand molding. Background technique [0002] Casting is the process of pouring smelted metal liquid into the mold, cooling and solidifying to obtain the required shape and performance of the parts. Casting is a commonly used manufacturing method with low manufacturing cost and high process flexibility, and complex shapes and large castings can be obtained. Due to the improvement of casting quality, casting precision, casting cost and casting automation, casting technology is developing in the direction of precision, large-scale, high-quality, automation and cleaning. Casting technology, special casting technology, casting automation and casting molding simulation technology have developed rapidly. [0003] At present, casting the steering column connecting plates of motorcycles, tr...
