Embodiment Construction

[0022] Next, in conjunction with the accompanying drawings, the specific embodiments of the mold mouth and the casting mold of the present invention will be described in detail.

[0023] attached figure 1 Shown is a three-dimensional view of the mold opening 10 according to this specific embodiment, the mold opening is in the shape of a ring, with the attached figure 2 is attached figure 1 Sectional view along any diameter. Reference attached figure 1 and attached figure 2 , the shown mold mouth 10 includes an inner bayonet 101 with a body 100 sleeved to a ceramic sleeve and an arc-shaped opening 102 facing the filter screen, and the material of the mold mouth 10 is ceramic, not metal.

[0024] The advantage of using ceramic material for the mold pot 10 is that it has a long service life, which is generally replaced once every 30-60 days, while the existing iron pot needs to be replaced every 1-2 days. In addition, the ceramic soup mouth riser has a better effect of bre...

Abstract

The invention relates to a liquid discharge opening of a die, which comprises an internal clamping mouth sleeved to a ceramic pipe sleeve, and an arc-shaped opening towards to a filter screen, wherein the material of the liquid discharge opening is ceramic. The invention has the advantages that the usage life of the ceramic liquid discharge opening is long, the ceramic liquid discharge opening can be replaced every 30-60 days; the ceramic liquid discharge opening has good effects of riser and liquid discharge break, the core break (riser) phenomenon is not easy to generate; the phenomena of draft and aluminum viscidity generated during the casting process can be effectively reduced, the casting process is smooth; the castability is stable, the production cycle is reduced, the output is increased; the circumference of a central hole of a bottom die can be effectively protected from aluminum water corrosion, thereby the die preparation labor hour can be minimized.

Description

technical field [0001] The present invention relates to a casting improvement process, in particular to a mold pot and a casting mold. Background technique [0002] The soup mouth, also known as the feed mouth, is one of the necessary parts in the casting mold. During the casting process, the molten metal slurry needs to be poured into the mold, and the soup mouth can prevent the slurry from flowing out. [0003] The existing low pressure casting mold mouth is mainly made of iron material, and the disadvantages are as follows. [0004] 1. The iron soup mouth has a short service life and is easily corroded by metal slurries such as aluminum water. Generally, it needs to be replaced after 3-5 shifts of production, which increases the production cost and mold preparation time. [0005] 2. It is easy to stick to the metal around the soup mouth, resulting in the situation of drafting, sticking to aluminum, and breaking the core, and it is easy to break the riser when the mold i...
