A method of laying a pouring system

Abstract

The invention discloses a pouring system paving method, which comprises: (1) drawing: drawing a two-dimensional picture by using CAD software, wherein the drawing contents comprise a mold placement position border, a gate positioning border, a mold inner gate position size border, a horizontal runner position border and a straight runner position border. According to the present invention, the two-dimensional picture is drawn through the CAD software, the two-dimensional picture is projected onto a working table through a projector, a horizontal runner porcelain tube, a mold, an inner gate porcelain tube and a straight runner porcelain tube are paved, a first pneumatic rod drives an ultrasonic wave sensor to detect the paving of the horizontal runner porcelain tube and the inner gate porcelain tube, the influence of the leakage caused by the non-flat paving on the pouring is avoided, a second pneumatic rod stably inserts the bundled horizontal runner porcelain tube into the inner gateporcelain tube, the whole process is rapid, efficient and stable, different two-dimensional pictures can be replaced according to different molds, the operation can be performed without professionals,the working efficiency is high, and the pouring error cannot be easily generated.

Description

technical field [0001] The invention relates to the field of pouring system laying methods, in particular to a pouring system laying method. Background technique [0002] When designing the casting process of large steel castings, considering the impact on the core and cavity and reducing the oxidation of molten steel, a bottom pouring gating system is generally used to allow molten steel to flow from the bottom of the casting into the cavity of the mold, and through process calculation In order to ensure the smoothness of the molten steel during the filling process and reduce the entrainment and splash caused by turbulent flow, the runners must be laid flat; due to the size and size of large castings and The tonnage is large, and the static pressure head of the molten steel is very large during the pouring process. If the strength of the pouring system is low, it is easy to cause sand washing or fire escape. In the actual molding process, the pouring system is laid during ...

AI Technical Summary

Problems solved by technology

Due to the large number of gates in large steel castings, the gating system is complicated, and the available time of resin sand is only 40 minutes, which will largely lead to imprecise laying operations of the gating system

It directly leads to the problems that the runners are not on the same plane and the loose sand flows into the runners during the laying process of the pouring system, which affects the surface quality of the castings and the fluidity of the molten steel during the pouring process.
