[0042] like figure 1 and Image 6 Among them, the first bumps 3 are evenly distributed on the second mold 4, and the second mold 4 forms a disassembly structure on the first mold 2 through the first bumps 3, and the first bumps 3 play a positioning role, increasing the second The accuracy of the connection position of the second mold 4 and the first mold 2, such as figure 1 The minimum distance between the outside of the third mold 6 and the second mold 4 is equal to the minimum distance between the outside of the third mold 6 and the first mold 2, and the third mold 6 is connected to the first mold through the second bump 5. 2 and the second mold 4 are connected by slots, so that the finished product is relatively uniform, and the third mold 6 can be positioned through the second bump 5, increasing the accuracy of the connection position between the third mold 6 and the first mold 2 and the second mold 4 sex;
[0043] like figure 1 The longitudinal section shape of the first connecting rod 9 is "T" shape, and the first connecting rod 9 is connected with the feeding port 8 by threaded connection, so the position of the first connecting rod 9 can be controlled to ensure the first connection. When the top of the rod 9 is in contact with the upper surface of the blanking port 8, the lower surface of the first connecting rod 9 is parallel to the upper surface of the second mold 4, thereby ensuring the smoothness of the upper surface of the finished product; figure 1 The bottom of the middle heating rod 11 has a spiral structure, and the distance between the four sides of the bottom of the heating rod 11 and the inner wall of the water tank 10 is equal, so that the water in the water tank 10 is heated evenly, thereby achieving the effect of uniform heating for the raw materials;
[0044] like Figure 7 The first heat dissipation device 15 includes a first heat pipe 1501, a first spring 1502, a first heat conduction block 1503 and a rubber block 1504. The left side of the inner wall of the first heat pipe 1501 is fixedly connected with a first The heat conduction block 1503, the right side of the first heat conduction block 1503 is pasted with a rubber block 1504, such as Figure 7 The first heat conduction block 1503 forms a telescopic structure on the first heat conduction tube 1501, and the right outer side of the first heat conduction block 1503 has a porous structure, so the heat can be dissipated rapidly through the holes on the first heat conduction block 1503, and the first spring 1502 The elastic effect of the first heat conduction block 1503 can be easily moved out of the device, so as to achieve the purpose of heat dissipation;
[0045] like figure 1 and figure 2 Among them, two first heat sinks 15 and two first motors 18 are arranged symmetrically with respect to the vertical central axis of the third mold 6, and the vertical central axis of the first heat sink 15 and the vertical central axis of the first motor 18 are located at On the same vertical plane, the fan 19 can specifically increase the air circulation velocity around the first heat dissipation device 15, thereby achieving the purpose of rapid heat dissipation;
[0046] like Figure 4 and Figure 8 The third connecting plate 2003 forms a rotating structure on the third connecting rod 2005, and the third connecting plate 2003 forms a telescopic structure on the second connecting plate 2001. The rotation of the third connecting plate 2003 can drive the rubber hammer 2004 to hit the first A mold 2 and a second mold 4, and the rubber hammer 2004 can swing back and forth through the elastic action of the second spring 2002, thereby achieving the effect of discharging the gas in the raw material through impact, such as Figure 4 and Figure 8 The middle rubber rod 23 forms a rotating structure on the table frame 1 through the connecting plate 22, and the distance between the side of the rubber rod 23 away from the connecting plate 22 and the connecting plate 22 is greater than the distance between the bottom of the third connecting plate 2003 and the connecting plate 22 size, the rotation of the third connecting plate 2003 can be powered by the rubber rod 23 .
[0047] Working principle: When using the casting production device for preventing cavities in castings, first connect the second mold 4 with the groove of the first mold 2 through the first bump 3, and the first bump 3 acts to connect the second The role of the positioning of the mold 4 makes the connection position between the first bump 3 and the first mold 2 more accurate, and then the first connecting plate 12 is respectively connected with the second mold 4 and the slot of the first bump 3, and then the second bolt 13 successively pass through the first connecting plates 12 on the left and right sides and then threadedly connect with the nut 14. Turning the nut 14 clockwise can reduce the gap between the two first connecting plates 12, so that the second mold 4 and the first connecting plate 12 can be connected One mold 2 is firmly fixed, and then the third mold 6 is connected with the second mold 4 and the first mold 2 through the second bump 5, and then the first bolt 7 is inserted through the third mold 6 and the first mold 2 and the first mold 2. The first bump 3 is threaded to fix the third mold 6, thereby completing the assembly work of the mold;
[0048] Then the heating rod 11 is switched on to heat the water in the water tank 10, and then the raw material is poured into the first mold 2 and the first bump 3 through the discharge port 8, and the heat in the water tank 10 will pass through the third mold 6 to Raw material transmission can increase the fluidity of raw materials, and ensure that the gaps in the first mold 2, the second mold 4, and the third mold 6 can be filled, and after filling, the power supply of the second motor 21 whose model is Y90S-2 When the switch is turned on, the second motor 21 will drive the rubber rod 23 to rotate through the connecting plate 22. When the rubber rod 23 rotates and contacts the third connecting plate 2003, it will push the third connecting plate 2003 to rotate on the third connecting rod 2005, so that The rubber hammer 2004 bumps into the first mold 2 and the second mold 4, and when the rubber rod 23 leaves the surface of the third connecting plate 2003, the rubber hammer 2004 will move toward the second connecting plate 2001 due to the elasticity of the second spring 2002. Return to the original position, through the rotation of the rubber rod 23, the rubber hammer 2004 can be driven to continuously hit the first mold 2 and the second mold 4, and the air in the raw material can be discharged through the discharge port 8 after being hit;
[0049] After the exhaust is completed, the second motor 21 and the heating rod 11 are turned off, and then the first connecting rod 9 is rotated so that the top of the first connecting rod 9 is in contact with the upper surface of the feeding port 8, and the feeding port 8 Closed to prevent the device from vibrating due to the operation process during the cooling process, thereby sticking to the feeding port 8, causing the blocking of the feeding port 8 or causing the finished product to be uneven here, and then the fixing plate 17 is connected to the second connection. After the rod 16 rotates 90° and leaves the surface of the first heat sink 15, the first heat conduction block 1503 will move outward due to the elastic action of the first spring 1502, and the heat in the raw material will be transferred to the first heat conduction block through the first heat conduction pipe 1501 1503, through the first heat conduction block 1503, then turn on the power switch of the first motor 18 of model Y90S-2, and the first motor 18 drives the fan 19 to rotate, thereby driving the air circulation around the first heat conduction block 1503, And the first heat conduction block 1503 has a porous structure, so the heat dissipation speed is faster. At the same time, the rotation of the rubber handle connection block 2403 drives the second heat conduction block 2402 to turn out of the third mold 6, and the heat in the water tank 10 will pass through the second heat conduction block. The tube 2401 is transferred to the second heat conduction block 2402 and discharged outwards, so as to increase the cooling speed, and the right side of the first heat conduction block 1503 and the top of the second heat conduction block 2402 are respectively provided with rubber blocks 1504 and rubber handles to connect Block 2403, when the rubber block 1504 is in contact with the first mold 2 or the second mold 4, the heat cannot be dissipated outwards and does not affect the pouring process. When the rubber handle connection block 2403 contacts the third mold 6, the heat in the water tank 10 also cannot be distributed;
[0050] After cooling and solidifying, unscrew the nut 14 from the second bolt 13 and extract it from the first connecting plate 12, then turn the first bolt 7 counterclockwise to take it off from the third mold 6, and then the third mold 6 1. When the first mold 2 and the second mold 4 are separated, the finished product can be easily taken out, which is the whole process of using the production device for castings to prevent cavities from being produced in the castings.
