Problems solved by technology

The riser can prevent defects to a certain extent, but cutting the riser requires a lot of energy consumption, and it is difficult to polish and clean the riser, which increases the labor intensity of the staff
At the same time, during the pouring process, due to poor exhaust or external air entering the mold cavity through the riser, the pattern is burned and gasified at high temperature, and the gas is involved to cause choking, resulting in large-area holes and irregular cracks in the profile. Trachoma, resulting in low casting pass rate

Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see figure 1 , a resin sand ductile iron riserless casting mold, including a mold 1 integrally formed to form a casting cavity and a plurality of air outlet needles 2 arranged on the mold, the mold 1 is used to live on the base of an elevator motor The gas outlet needle 2 is used for exhausting during the solidification shrinkage and graphitization expansion process of the module, so as to reduce the gas pressure in the cavity and improve the filling capacity of the molten metal.

[0020] The invention adopts...

Abstract

The invention provides a resin sand ductile iron feederless casting mould which comprises a section mould integrally molded to form a casting cavity, and multiple air outlet needles arranged on the section mould. The multiple air outlet needles are arranged along the direction perpendicular to a horizontal plane on which the section mould is located. Compared with the prior art, according to the resin sand ductile iron feederless casting mould provided by the invention, the production efficiency is improved, the product quality is improved, and the acceptability is high.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a resin sand ductile iron riserless casting mold. Background technique [0002] The gating system is the channel opened to introduce the molten metal into the pattern during pouring, mainly including the sprue and the inner sprue. The top of the sprue is connected to the outside world, and the bottom is vertically connected to the runner. The runner is arranged near the pattern. The runner and the pattern are connected through the inner runner. The riser is a cavity used to store molten metal. It can replenish molten metal during the casting forming process, prevent shrinkage and shrinkage defects of the casting, and play the role of exhaust and slag collection. The riser prevents the generation of defects to a certain extent, but the energy consumption required for cutting the riser is large, and it is difficult to polish and clean the riser, which increases the labor i...
