Problems solved by technology

For sand casting, the general gating system is formed by molding sand. Due to the long-term erosion of high-temperature molten iron, it is easy to cause sand inclusion defects in castings.
[0003] The prior art provides a ceramic pouring pipe system, which adopts a main pouring pipe composed of multiple pipe fittings and a secondary pouring pipe connected with the main pouring pipe, and effectively avoids stress concentration by arranging the multiple pipe fittings of the main pouring pipe in different diameters. It brings the problem of uneven air pressure that leads to the decline of casting quality, but at the same time it brings the following disadvantages: the pipe fitting joint is inconvenient in actual use, and the inside of the pipe fitting cannot be cleaned after molding; there are many sizes and specifications, and for the production of large castings, multiple interiors are required In the runner, the connection is complicated, difficult to control, and the efficiency is low; the slag blocking and slow flow effect of the gating system itself is not obvious, and the gating system cannot reduce the problem of slag inclusion

Abstract

The invention discloses a casting all-ceramic pouring mechanism. The casting all-ceramic pouring mechanism comprises a sprue pipeline, sprue bases, a cross gate pipeline, a slag collection base, sprue passing plates and ingate pipelines. The sprue pipeline is connected to through holes of the sprue bases. The cross gate pipeline is connected to the slag collection base. The ingate pipelines are connected to the cross gate pipeline through the sprue passing plates.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to an all-ceramic pouring mechanism for casting. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. The pouring mechanism is a channel opened in the mold for introducing liquid metal into the mold cavity. The function of the pouring mechanism is to control the speed of filling the mold with the molten metal and the time required to fill the mold; to make the molten metal enter the mold smoothly. Type, avoid turbulence and flushing of the mold; prevent slag and other inclusions from entering the cavity; do not involve gas when pouring, and try to make the casting conform to the principle of sequential solidification when cooling. For sand casting, the general gating system is formed b...
