Problems solved by technology

However, this product is a large-volume and heavy-weight product that requires high pressure during the pouring process, and cannot effectively fill the cavity when the temperature of the molten iron is lowered, resulting in a high product rejection rate
In order to improve the fluidity of molten iron, it is necessary to increase the pouring temperature, but when the temperature is too high, it is easy to have pores and shrinkage porosity, which will increase the production cost of the enterprise

Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing:

[0009] Such as figure 1 As shown, a large-scale aluminum water vessel casting device consists of an upper sand mold 1, a metal positioning cone 2, a fastening bolt 3, a sprue 4, an inner runner 5, a riser 6, an upper part of the lower sand mold 7, and a lower sand mold. Part 8, cold iron 9, composition, characterized in that: the bottom of the lower part 8 of the lower sand mold is covered with cold iron 9, and the upper sand mold 1 and the lower sand mold 7, 8 should be heated to 70 o-80 o in the oven before they are combined. After positioning the box with the metal positioning cone 2, it is connected with the fastening bolt 3. The sprue 4 and the inner runner 5 are composed of ceramic tubes with a diameter of 120mm. The height difference between the upper and lower runners 5 is 700mm, and they are designed at an angle of 135° to the casting body. The riser 6 adopts 8 h...

Abstract

The invention relates to a casting device and in particular to a large-scale casting device for an aluminum-water utensil. The large-scale casting device consists of an upper sand mould, a metal positioning cone, a fastening bolt, a straight pouring gate, inner pouring gates, a dead head, a lower part of the lower sand mould, an upper part of the lower sand mould and cold iron. The large-scale casting device is characterized in that the straight pouring gate is perpendicular to the ground, the upper and the lower inner pouring gates are in angled design; molten water forms two different pressure differences in the inner pouring gates to ensure that the molten iron can fill up a utensil mould cavity within the shortest time; the straight pouring gate and the inner pouring gates consist of ceramic tubes with inner wall diameter of 120 mm; the upper sand mould and the lower sand mould are positioned through the metal positioning cone, and are connected through the fastening bolt after being closed; the dead head is a heating thermal-insulation dead head with diameter of 180 mm; feeding for casting pieces is relatively sufficient, and a self-utilization rate of the molten iron is greatly increased. The large-scale casting device has the advantages of being simple in structure, reasonable in design, time-saving and labor-saving, high in molten iron utilization rate, high in efficiency, good in casting piece surface quality, and the like.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting device for a large aluminum water vessel. technical background [0002] Due to the large size and heavy quality of the current casting utensils, the casting process generally adopts the bottom pouring method. The molten iron flows smoothly, and impurities and gases in the molten iron are easily removed from the body of the casting. But this product needs very high pressure in the pouring process for the heavy product of volume, can not effectively fill cavity in the molten iron temperature reduction process, and product reject rate is higher. In order to improve the fluidity of molten iron, it is necessary to increase the pouring temperature, but when the temperature is too high, pores and shrinkage porosity are prone to occur, which increases the production cost of the enterprise. Contents of the invention [0003] The technical problem to be solved by the present invention...
