[0017] The present invention provides a casting mold for a CNC machine tool casting, which has the following beneficial effects:

[0018] (1) The present invention uses a circular frame, a sub-cavity block, a mother block, a U-shaped pull frame, a pouring pipe, an axis plate, a cross plate, a U-shaped groove plate, an arc-shaped elastic strip, an electric telescopic rod, a square block, a magnetic column and a round iron block.

[0019] (2) The present invention arranges a stabilizing device so that the L-shaped plate, roller, arc-shaped bridge plate, square plate, semi-arc plate, sliding column and disc cooperate with the spring. When the sub-cavity block is merged with the mother block, the roller rolls on the arc-shaped bridge plate, so that the sub-cavity block and the mother block can be stably merged, and the sub-cavity block and the mother block are prevented from shaking when they are merged, causing damage to the mud and sand molds of the sub-cavity block and the mother block. Moreover, under the elastic force of the spring, when the sub-cavity block and the mother block are merged, the sliding column rests on the square plate, so that the sub-cavity block and the mother block will not collide with each other when they are merged, and the mold is prevented from being damaged by collision when the sub-cavity block and the mother block are merged.

[0020] (3) The present invention arranges a heat-conducting device so that the U-shaped rod, the ring plate, the circular plate, the semiconductor refrigeration plate, the short column and the arc-shaped spring piece cooperate with the connecting block, and the semiconductor refrigeration plate cools the heat discharged from the exhaust hole groove of the sub-cavity block, so that heat will not accumulate above the exhaust hole groove of the sub-cavity block, thereby preventing the accumulation of heat above the exhaust hole groove of the sub-cavity block, which will cause the three-dimensional casting cooling molding of the CNC machine tool in the equipment to be poor. In addition, when the semiconductor refrigeration plate in the circular plate rotates upward, the semiconductor refrigeration plate on the circular plate will not vibrate, thereby preventing the semiconductor refrigeration plate from being damaged by vibration during displacement, which will cause poor equipment operation effect.

The semiconductor refrigeration plate 94 is located on the left side of the exhaust hole groove of the sub-cavity block 4. The semiconductor refrigeration plate 94 cools the heat discharged from the exhaust hole groove of the sub-cavity block 4, so that heat will not accumulate above the exhaust hole groove of the sub-cavity block 4, so as to avoid the accumulation of heat above the exhaust hole groove of the sub-cavity block 4 when the casting mold is in use, resulting in poor cooling and molding effect of the three-dimensional casting of the CNC machine tool in the equipment.

[0040] When the sub-cavity block 4 and the mother block 5 drive the L-shaped plate 81 to rotate upward, the L-shaped plate 81 drives the square plate 84 to rotate upward. At the same time, the L-shaped plate 81 drives the semi-arc plate 85 to rotate upward, and the semi-arc plate 85 drives the sliding column 86 to rotate upward, and the sliding column 86 drives the disc 87 to rotate upward, and the disc 87 drives the spring 88 to rotate upward. In the process of the sliding column 86 rotating upward, the sliding column 86 contacts the square plate 84. Under the action of the extrusion force, the sliding column 86 moves to the right in the sliding hole of the semi-arc plate 85, and the sliding column 86 drives the disc 87 to move to the right. The spring 88 on the disc 87 begins to stretch. Under the elastic force of the spring 88, when the sub-cavity block 4 and the mother block 5 are merged, the sliding column 86 is against the square plate 84, so that the sub-cavity block 4 and the mother block 5 will not collide with each other when they are merged, so as to prevent the sub-cavity block 4 and the mother block 5 from colliding with each other when the equipment is in use, thereby avoiding the problem of damage to the casting mold caused by the collision when the sub-cavity block 4 and the mother block 5 are merged when in use.

[0041] When the L-shaped plate 81 drives the square plate 84 to rotate upward, the square plate 84 drives the U-shaped rod 91 to rotate upward, the U-shaped rod 91 drives the ring plate 92 to rotate upward, the ring plate 92 drives the round plate 93 to rotate upward, and the round plate 93 drives the semiconductor refrigeration plate 94 to rotate upward. When the sub-cavity block 4 is merged with the mother block 5, the semiconductor refrigeration plate 94 stays above the exhaust hole slot of the sub-cavity block 4, the semiconductor refrigeration plate 94 is started, and the semiconductor refrigeration plate 94 begins to refrigerate. When the metal liquid enters the mud sand mold of the sub-cavity block 4 and the mother block 5, the heat of the metal liquid is discharged from the exhaust hole slot of the sub-cavity block 4, so that the semiconductor refrigeration plate 94 cools the heat discharged from the exhaust hole slot of the sub-cavity block 4, so that heat will not accumulate above the exhaust hole slot of the sub-cavity block 4, thereby preventing heat from accumulating above the exhaust hole slot of the sub-cavity block 4 when the equipment is in use, thereby avoiding the accumulation of heat above the exhaust hole slot of the sub-cavity block 4 when the casting mold is in use, resulting in poor cooling and molding effect of the three-dimensional casting of the CNC machine tool in the equipment.

[0042] While the ring plate 92 drives the circular plate 93 to rotate upward, the circular plate 93 drives the short column 95 to rotate upward, the short column 95 drives the arc-shaped spring piece 96 to rotate upward, and the arc-shaped spring piece 96 drives the connecting block 97 to rotate upward. Under the elastic force of the arc-shaped spring piece 96, the semiconductor refrigeration plate 94 in the circular plate 93 does not vibrate during the upward rotation process, thereby avoiding the problem of poor equipment operation effect caused by vibration damage of the semiconductor refrigeration plate 94 during displacement of the casting mold when in use.
