Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following description of the present invention with reference to the accompanying drawings and specific embodiments is provided for clarity and completeness.

As shown in fig. 1 to 4, a mold for casting a ladle liner includes: the tire membrane comprises a tire membrane body 1 and a support rib 2 arranged inside the tire membrane body 1; the fetal membrane body 1 comprises a first part body 3 and a second part body 4 positioned below the first part body 3, wherein the first part body 3 is in a hollow circular truncated cone shape with a wide upper part and a narrow lower part, and the second part body 4 is in a bowl shape with an open top; the brace rod 2 includes horizontal muscle 5 of a plurality of and erects muscle group 6, horizontal muscle 5 is the ring form, a plurality of horizontal muscle 5 is in by lower supreme evenly distributed on the inner wall of fetal membrane body 1, horizontal muscle quantity is four, erect muscle group 6 one end with second part body internal connection upwards extends along vertical direction. Further, the first part body 3 and the second part body 4 are integrally formed, and the support rib 2 is welded on the inner wall of the membrane body 1.

The bottom of the tire membrane is combined with the flat bottom, so that the problem that the bottom of the liner is easy to leak steel and pass through a bag after pouring by using a flat bottom mold only containing the flat bottom is avoided, the problem that the thickness of the molded liner is uneven due to the fact that the round bottom mold only containing the flat bottom is not easy to fix and incline is solved, and the problem that a honeycomb cavity is formed due to the fact that the round bottom mold is not easy to vibrate in place is solved. The supporting ribs 2 are arranged, so that the strength and rigidity of the mould are enhanced, the mould is not easy to damage, the service life is prolonged, and the mould is convenient to fix.

As shown in fig. 1, the membrane body 1 further includes a third body part 7 located above the first body part 3, the third body part 7 is in a hollow truncated cone shape, and sidewalls of two ends of the third body part are in a splayed shape, so that when a casting material is constructed, the material flows to a position between the mould and the ladle shell of the third body part 7. Further, the first part body 3, the second part body 4 and the third part body 7 are integrally formed, and the height of the support rib 2 is slightly lower than the upper plane of the third part body 7. The mould also comprises a plurality of hanging lugs 8, wherein the hanging lugs 8 are arranged on the side wall of the upper part of the third part body 7 and used for lifting and placing the mould.

The composition of the vertical rib group 6 includes, but is not limited to, the following two types:

the first kind, it includes the first perpendicular muscle 9 that a plurality of height equals, a plurality of to erect muscle group 6 the one end of first perpendicular muscle 9 with the axis of fetal membrane body 1 is the center, the other end evenly to the inner wall radiation of fetal membrane body 1, and with the inner wall of fetal membrane body 1 perhaps horizontal muscle 5 is connected, first perpendicular muscle 9 is ten, as shown in fig. 2. During construction, the vibrating rods can reach the center of the bottom of the tire membrane through the space between the adjacent vertical ribs 6, and the bottom of the tire membrane can also vibrate in place, so that a honeycomb cavity is prevented from being formed.

The second kind, erect muscle group 6 and include that the second that a plurality of edge first direction parallel arrangement and height equal erects muscle 10 and a plurality of along second direction parallel arrangement and height equal second and erect muscle 11, a plurality of muscle 10 and a plurality of are erected to the second erects 11 two liang of intersections of muscle, forms the cross, and a plurality of muscle 10 and a plurality of are erected to the second the both ends that the muscle 11 was erected to the second all with the inner wall of fetal membrane body 1 perhaps horizontal muscle 5 is connected. Further, the first distance between two adjacent second vertical ribs 10 is equal, the second distance between two adjacent second vertical ribs 11 is equal, and the first distance and the second distance are equal, as shown in fig. 3. During construction, the vibrating rod can vibrate the bottom of the tire membrane in place through a cavity between the second vertical rib 10 and the second vertical rib 11 of two adjacent vertical ribs.

When the casting material compacting device is used, firstly, casting material is placed in a ladle shell to form a ladle bottom, then a mould is placed on the upper portion of the ladle bottom through the hanging lugs 8, the mould can be easily fixed due to the fact that the bottom of the mould is a plane, after the mould is fixed, the casting material is poured between the mould and the ladle shell, the casting material is compacted through a vibrator or a vibrating rod, and then the casting material is molded. And demolding after pouring and forming. The demolded ladle shell was lined with an inner liner as shown in fig. 4.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
