Description
Technical Field
[0001] The utility model relates to the technical field of ductile iron casting, in particular to a ductile iron casting device. Background Art
[0002] Ductile iron is an iron-carbon alloy containing a large amount of spheroidal graphite. Ductile iron has the advantages of high plasticity and toughness, good wear resistance, and the ability to absorb heat and reduce shock. Due to its excellent mechanical properties and heat treatment properties, it is widely used in various fields, such as automobile manufacturing, machinery manufacturing, construction, etc. One of the most critical links in the production process of ductile iron workpieces is the casting process. In the production of existing ductile iron workpieces, the mold is first matched, the two molds are fixed by bolts, and then poured. The molten iron is transferred through the ladle to the pouring port of the mold, and then the internal molten iron is injected into the mold through the pouring port. After cooling, the mold is manually demolded to obtain a ductile iron workpiece. When pouring traditional ductile iron workpieces, a large number of bolts are needed to fix the mold to ensure the tightness and accuracy of the mold fit, which is very cumbersome. When demolding precision workpieces, manual demolding often causes uneven force on the mold, which makes demolding difficult or even damages the workpiece. For this reason, we propose a ductile iron casting device. Utility Model Content

[0024] The working principle of a ductile iron casting device provided by the utility model is as follows: when casting ductile iron, the ductile iron is melted into high-temperature molten iron by the furnace. During this period, the molds are first matched, and the left and right molds are respectively placed in the front and rear mold frames 2. The hand wheel 48 is turned forward, and the adjusting screw 47 also rotates and moves to the left, pressing the sliding frame 42 to move to the left synchronously, and the spring 46 is compressed by force. At this time, the limit groove 43 also moves to the left synchronously, and at the same time presses the extrusion block 44, and the extrusion block 44 moves to the middle of the mold frame 2. The inclined surface of the extrusion block 44 continuously presses the mold, so that the two molds move inward synchronously, so that the mold fixing effect is optimal, and the single piece The machine 8 controls the motor 492 to operate, and the output shaft of the motor 492 drives the bidirectional screw 493 to rotate forward. Because the middle of the inner lower end of the mold frame 2 is threadedly connected to the outer surface of the bidirectional screw 493, the two mold frames 2 move inward synchronously with the rotation of the bidirectional screw 493. The two guide columns 491 play a stabilizing and guiding role for the movement of the mold frame 2. The mold is embedded in the mold frame 2. The mold is driven to move by moving the mold frame 2. The two molds fit more closely and more accurately. At this time, the high-temperature molten iron is transferred by the steel ladle to the top of the mold group where the two molds are matched, and the molten iron is sequentially passed through the pouring bucket 7, The pouring port 6 and the feed port are injected into the interior of the mold group, and the air inside the mold group is discharged through the exhaust hole and the air hole 5. After the molten iron in the mold group is cooled, the mold frame 2 and the outer surface of the mold group are gently tapped to initially separate the mold group from the internal workpiece. The single-chip microcomputer 8 controls the operation of the motor 492, and the output shaft of the motor 492 drives the bidirectional screw 493 to reverse, and the two mold frames 2 move outward synchronously, and the two molds are also separated synchronously, which improves the guiding effect of the guide column 491, and the mold frame 2 moves more evenly and smoothly, and demoulding is easier, which minimizes the damage to the workpiece in the mold group until the two mold frames 2 move to When the workpiece is at a suitable distance, it can be taken out. When a different mold needs to be replaced, the hand wheel 48 needs to be reversed, and the adjusting screw 47 will also rotate and move to the right. The spring 46 will expand without force, driving the sliding frame 42 to move to the right, and the extrusion block 44 will also move synchronously in the direction away from the middle of the mold frame 2. The extrusion block 44 leaves the mold surface, and the mold loses its restriction, so the new mold can be quickly replaced. Different molds can be quickly fixed and matched, while ensuring the tightness and accuracy of the mold fit, and can automatically and evenly perform demolding to prevent demolding difficulties or even damage to the workpiece due to uneven force.
