[0003] In the patent of the sprue basin whose application number is CN201020675816.1, it includes a basin body and a sprue. The inner wall of the sprue is provided with a support step, and a filter is arranged on the support step. The sprue in this patent is only for The fixed filter does not have the function of pressurization, and the filter can only filter impurities or scum in the molten metal. When used as a channel component connecting the ladle and the pouring system, it cannot prevent air entrainment and prevent Due to the effect of siphon, the molten metal entering the sprue from the gate still has the problems of entraining gas and siphoning slag. The sprue basin with the filter is only suitable for pouring small castings, and cannot meet the pouring requirements of large castings, for example Pouring liquid reaches one ton to ten tons

Embodiment Construction
[0025] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. Ordinary technicians can also obtain other drawings based on these drawings on the premise of not paying creative work.
[0026] see Figure 1 to Figure 4 , the embodiment of the present invention provides a supercharged anti-slagging sprue basin, including a basin body 10, a pressurization nest 20 arranged at the bottom of the basin body 10, and a gate assembly 30 arranged in the pressurization nest 20. The socket 20 is close to the cup wall of the basin body 10. The pressurization socket 20 is a hollow cylinder or a hollow prism extending downwardly from the bottom of the basin body 10. A gate assembly is arranged at the bottom of the pressurization so...

Abstract
The invention relates to a pressurizing slag absorption resistant pouring basin. The pressurizing slag absorption resistant pouring basin comprises a basin body, a pressurizing nest and a pouring assembly, wherein the pressurizing nest is arranged at the bottom of the basin body, the pouring assembly is arranged in the pressurizing nest, the pressurizing nest is close to the cup wall of the basin body, the pouring assembly is arranged at the bottom of the pressurizing nest, the pouring assembly comprises a ceramic pouring seat, a pouring plug and a connecting rod, the ceramic pouring seat is a hollow cylinder, and the pouring plug covers an upper opening of the ceramic pouring seat, so that the upper opening of the ceramic pouring seat is plugged. According to the pressurizing slag absorption resistant pouring basin, the pressurizing nest is arranged at the bottom of the pouring basin, the pouring assembly is arranged in the pressurizing nest, the pouring assembly is filled with molten metal in the pressurizing nest, the molten metal enters a sprue through the pouring assembly, and the molten metal which enters the pressurizing nest is far from siphon action by the pouring assembly, so that scum and oxides on the upper part of the molten metal are adhered to the bottom of the pouring basin and the side wall of the pressurizing nest or float above the sprue, and clean molten metal can be flushed into a casting mold.
Description
technical field [0001] The invention relates to the technical field of gravity casting, in particular to a supercharged slag-absorbing anti-slag sprue basin. Background technique [0002] Casting molten metal pouring system is usually composed of sprue basin, sprue, runner, ingate, and gas outlet. The pouring system should make the molten metal clean and fill the mold with the minimum rising speed to obtain a clean For castings, the sprue basin is used to receive the molten metal from the ladle and connect with the sprue to form a channel for the molten metal to enter the mold, and it can reduce the impact of the molten metal on the mold and prevent slag and debris , The effect of gas entering the cavity. [0003] In the patent of the sprue basin whose application number is CN201020675816.1, it includes a basin body and a sprue. The inner wall of the sprue is provided with a support step, and a filter is arranged on the support step. The sprue in this patent is only for Th...
