Problems solved by technology

[0007] Aiming at the problems that ceramic sprue cups are easy to crack and hot metal splashes when pouring high-temperature molten iron, the present invention designs a high-temperature-resistant foam sprue cup and its processing technology. By improving the shape of the sprue cup, the When the molten iron is poured, it can prevent the molten iron from swirling and sputtering in the main body of the sprue cup, and by coating the outer wall of the sprue cup with a layer of high-temperature resistant layer, it can prevent the problem of cracking when the molten iron is poured, and the material for preparing the high-temperature resistant layer is cheap , reducing production costs

Embodiment

[0033] A kind of high temperature resistant foam sprue cup and its processing technology of the present embodiment, such as Figure 1 to Figure 3 As shown, the sprue cup 1 is made of foam and includes a sprue cup body 11 and a sprue channel 12 connected thereunder. The diameter of the sprue cup 1 gradually decreases from top to bottom. The sprue cup body 11 The cross-section of the sprue cup body 11 is asymmetrically elliptical, and the cross-sectional area of ​​the sprue cup body 11 is larger than that of the gate channel 12, and the gate channel 12 is circular or square; The entrance of the cup 1 is pasted with a cloth film seal 3, and the outer wall of the sprue cup 1 is coated with a high temperature resistant layer 2.

[0034] The shape design of the main body 11 of the sprue cup is compared with the sprue cup 1 of the positive taper. When the molten iron is poured, it can prevent the molten iron from spinning and splashing out in the sprue cup 1, causing harm to the work...

Abstract

The invention discloses a high-temperature-resistant foam pouring cup and a processing technology thereof, and belongs to the field of lost foam casting. The pouring cup is made of foam and comprisesa pouring cup body and a pouring channel connected to the lower portion of the pouring cup body, and the cross section area of the pouring cup body is larger than that of the pouring channel. A clothfilm seal is attached to an inlet of the pouring cup, and the outer wall of the pouring cup is coated with a high-temperature-resistant layer. The outer wall of the foam pouring cup is coated with thehigh-temperature-resistant layer, the pouring cup is made of foam, and the high-temperature-resistant layer can be better bonded to the outer wall of the pouring cup so that the problem of cracking due to molten iron pouring can be solved, the price of materials for preparing the high-temperature-resistant layer is low, and the production cost is reduced; and the shape of the pouring cup is improved so that molten iron can be prevented from swirling and splashing in the pouring cup during molten iron pouring, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of lost foam casting, in particular to a high temperature resistant foam sprue cup and its processing technology. Background technique [0002] The casting process is inseparable from the sprue cup. The traditional sprue cup manufacturing process is: using green mold sand in a thin iron film to make it by hand. However, the sprue cup produced by this process tends to show unevenness in the lower part and the upper part is thin, and the surface quality is poor, and the thermal strength of the molding sand is low. It is easy to cause sand holes in the casting during the pouring process, so the quality of the casting produced is stable. Poor performance and high reject rate. And for green mold sand manual molding production process: on the one hand, the production efficiency of this process is low, the amount of sand used is large, and the human factors in the operation are greatly affected; Otherwise, the sprue cup wi...
