Abstract

The invention discloses a casting process of a clay cylinder. The casting process of the clay cylinder includes following steps: manufacturing a metal mould of the clay cylinder; preparing a manufacturing tool; arranging a sprue gate, a riser and an air outlet on the mould; placing resin sand into the metal mould to mould the resin sand; patching the molded resin sand mould and painting the surface of the mould; arranging and assembling the resin sand mould; lifting a box of the resin sand mould; placing a sprue cup on the sprue gate of the mould, and placing a riser cup on the riser of the mould; and casting melted iron into a cavity of the resin sand mould by the aid of a crane ladle for grey chiller casting. The casting process of the clay cylinder has the advantages of high accuracy, saving in materials, simple steps, and improved production efficiency.

Description

Technical field: [0001] The invention relates to a casting process of clay cylinders. Background technique: [0002] At present, the production process of clay cylinders is to first use sand molds for gray iron casting, and then carry out a series of machining on the cast blanks with machining allowances, including planing the reference plane, milling both ends, boring the inner wall, scribing Wire drilling, deburring, etc. This process is more complicated, the investment in equipment is large, the production efficiency is low, and the cost of the clay cylinder is high, the surface hardness is low, and the service life is short. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a clay cylinder casting process with high precision, material saving, simple steps and high production efficiency. [0004] The object of the present invention is achieved through the following technical solutions: a casting process ...
