Abstract

The invention discloses an inside race on a slip flask, belonging to a slip flask and comprising an upper inside race, a flange and a blade, wherein the inside race on the slip flask is in a circle, hexagon or square shape, the excircle at the bottom of the circular upper inside race (2) is provided with the circular flange (1), the inner wall of the bottom is provided with the blade (3) or not provided with the blade; the hexagon flange (4) is arranged outside the hexagon upper inside race (5), and the inner wall of the bottom is provided with the blade (3) or not provided with the blade; and the square flange (6) is arranged outside the square upper inside race (7), and the inner wall of the bottom is provided with the blade (3) or not provided with the blade. The invention has the advantages of good compactness of moulding sand after sliding out of the slip flask, firmness, no deformation, no mould raising when casting products, no water leakage, less scrapped products and high profit.

Description

Inside race on slip flask

Technical field: the present invention relates to the sand fallout case of living, particularly a kind of inside race on slip flask.

Background technology: in China's foundry industry, all be to adopt outer casing, it is an encased again case after having made type, belongs to the secondary casing, finish moulding, casting with secondary like this, product is easily lifted case, swell, and the product burr is many, product thickens, processing take a lot of work, time-consuming, waste energy.China all adopts artificial bedded-in moulding, the development that fetters the productive forces in most areas.

Summary of the invention: the object of the present invention is to provide a kind of inside race on slip flask, utilize the die casting simultaneously of cope inside race and molding sand can become top box integral body, product is not lifted case during casting, and is water-tight, reaches the low and high purpose of casting efficient of percent defective.

Formation of the present invention: be made up of last inside race, flange and blade, inside race on slip flask has circle, hexagon or square, is round flange on inside race bottom cylindrical on the circle, and blade or on-bladed are arranged on the bottom interior wall; On hexagon, outside the inside race bottom hex flange is arranged, blade or on-bladed are arranged on the bottom interior wall; On square, outside the inside race bottom square flange is arranged, blade or on-bladed are arranged on the bottom interior wall.

On the circle inside race upper-thin-lower-thick coning, the inside race upper-thin-lower-thick becomes the hexagon taper on the hexagon, the inside race upper-thin-lower-thick becomes four limit tapers on the square.

Blade is distributed in the circular inside race and square gone up on inside race, the hexagon and goes up inside race inwall below, and the bottom is concordant with last inside race bottom, and the top is by the inwardly below inclination of last inside race inwall, upper-thin-lower-thick, free end wedgewise.

Compared with the prior art, the present invention is provided with cope inside race and drag box inside race respectively in the sand fallout case of living up and down, drag box inside race and molding sand die casting simultaneously in the utilization can become up and down integral body separately, and the degree of packing of molding sand is good behind the drawing, be difficult for destroyed, indeformable, product is not lifted case during pouring, and is water-tight, product rejection rate is low, the efficient height.The present invention adds the disposable operation of inside race on slip flask with machine moulding and finishes the case of moulding and count quality and can both be doubled at double, this invention development of liberating the productive forces again like this, and innovation achievement is remarkable.In the last inside race blade is set, can be the time with the sand molding delivery, molding sand is difficult for loosening, is difficult for the case that collapses when removing case, is difficult for lifting case, swell during the molten iron casting, and the burr of product is still less like this.

Description of drawings: Fig. 1 is vaneless circular inside race on slip flask structure chart, Fig. 2 is vaned circular inside race on slip flask structure chart, Fig. 3 is the A-A cutaway view of Fig. 2, Fig. 4 is vaneless hexagon inside race on slip flask structure chart, Fig. 5 is vaned hexagon inside race on slip flask structure chart, Fig. 6 is the B-B cutaway view of Fig. 5, Fig. 7 is vaneless square inside race on slip flask structure chart, Fig. 8 is vaned square inside race on slip flask structure chart, and Fig. 9 is the C-C cutaway view of Fig. 8.

1. round flanges among the figure, 2. circular last inside race, 3. blade, 4. hex flange, 5. inside race on the hexagon, 6. square flange, the 7. last inside race of square.

The specific embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Figure 9, form by last inside race, flange and blade, inside race on slip flask has circle, hexagon or square, on the 2 bottom cylindricals of inside race on the circle is round flange 1, and blade 3 or on-bladed are arranged on the bottom interior wall; On hexagon, outside inside race 5 bottoms hex flange 4 is arranged, blade 3 or on-bladed are arranged on the bottom interior wall; On square, outside inside race 7 bottoms square flange 6 is arranged, blade 3 or on-bladed are arranged on the bottom interior wall.

On the circle inside race 2 upper-thin-lower-thicks coning, inside race 5 upper-thin-lower-thicks become the hexagon taper on the hexagon, inside race 7 upper-thin-lower-thicks become four limit tapers on the square.

Blade 3 is distributed in the circular inside race 5 and square gone up on inside race 2, the hexagon and goes up inside race 7 inwalls below, and the bottom is concordant with last inside race bottom, and the top is by the inwardly below inclination of last inside race inwall, upper-thin-lower-thick, free end wedgewise.
