Mold for casting metal floor block

Abstract

The invention relates to a mold for casting a metal floor block. The mold is formed by integrally welding a mold bottom plate and a mold frame plate into a whole, and further comprises a lower half mold and an upper half mold, wherein a drill hole of the lower half mold is a positioning hole; a positioning pin of the upper half mold is matched with the positioning hole, so that the upper and lowermolds are prevented from deviating; a drawing slot is further processed on the upper half mold and is used for drawing to open the upper and lower molds; a trapezoid hole is processed in the center of an upper mold plate and is used for installing a pouring gate sand mold piece; four trapezoid holes are processed on the edge part of the upper mold plate and are used for installing feeder head sand mold pieces; and finally, a sand mold pressing plate at the uppermost end of the mold is used for pressing the five sand mold pieces, and molten iron is injected into a cavity formed by the upper and lower molds from a center hole in the sand mold pressing plate through a middle hole of the pressed pouring gate sand mold piece, and is upwards fully injected from the cavity through middle holes of the four feeder head sand mold pieces, so that after cooling, the metal floor block is formed. The metal floor block produced through casting can achieve the aims of high quality, high efficiency and energy conservation of products.

Description

Technical field: [0001] The invention relates to a mold, in particular a mold for casting metal floorboards. Background technique: [0002] At present, the known metal castings mostly adopt the traditional method. At first, the wooden mold of the casting is processed. When making the wooden mold, the size of each part of the wooden mold should be increased. On the one hand, the shrinkage coefficient of molten iron when casting the workpiece is considered; The second is to consider the mechanical processing of castings to increase the machining allowance. This casting process is to put the processed wooden mold into the sand box to manufacture the sand mold of the casting workpiece. When manufacturing the sand mold, it is divided into the upper sand box and the sand box. The lower sand box, the upper and lower sand boxes are integrated to form the sand cavity of the casting. In the center of the upper sand box, there is a casting port for the sand mold. The molten iron is inj...

Problems solved by technology

Some large-scale machine tool bed parts, some large-scale equipment mechanical parts, it is necessary to apply traditional technology, but at present, small-scale castings are cast all over the country, especially mass-produced castings, and the traditional old technology cannot keep up with the times The requirements of technological development, the production method of this old craft of foundry casting, low efficiency, low product qualification rate, large amount of casting processing, waste of machine tool processing time, waste of machine tool processing time, is the lack of waste of electric energy
