Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy die-casting molds, in particular to an aluminum alloy casting die-casting mold. Background Art

[0002] Aluminum alloy die casting is a common casting process used to produce aluminum alloy parts with complex shapes. Die casting involves injecting liquid aluminum alloy into a metal mold under high pressure, where it solidifies and cools to produce the desired aluminum alloy casting.

[0003] After the existing gasoline vehicle water pump aluminum alloy accessories are die-cast through the die-casting mold, an ejection mechanism is needed to first eject the water pump aluminum alloy accessories from the inside of the fixed mold, and then a robot is used to take them away. During this process, the water pump aluminum alloy accessories are very likely to fall directly onto the machine base below and collide with it, which is not conducive to the subsequent robot taking them up, and will also cause certain damage to the surface of the water pump aluminum alloy accessories; and, since the temperature of the water pump aluminum alloy accessories is still high and higher than the temperature of the indoor air when they are ejected from the mold, if the robot is in direct contact with the outside of the water pump aluminum alloy accessories with a high temperature for a long time and multiple times, it is very easy to damage the coating on the surface of the robot accessories, thereby affecting the subsequent normal use of the robot.

After die-casting, the aluminum alloy liquid becomes an aluminum alloy casting 10. After subsequent cooling and demolding, the servo motor 39 is started. The servo motor 39 drives the screw rod 13 to rotate, and the screw rod 13 then drives the movable mold base 4 and the movable mold 6 to move to one side until the movable mold die-casting cavity is separated from one side of the aluminum alloy casting 10.

[0033] like Figure 2-6 and Figure 8 As shown, a moving support mechanism is provided on the inner side of the moving port 7, and the moving support mechanism includes a sliding rod 8, and two support members 9 are movably provided on both sides of the sliding rod 8.

The first pull rope 22 is arranged inside the sliding rod 8 and near the upper side. The two sides of the connecting piece 23 are respectively fixedly connected to the second pull ropes. The outer ends of the two second pull ropes 24 pass through the two sides of the sliding rod 8 and are fixedly connected to the inner sides of the two support members 9. The drive motor 40 is started, and the drive motor 40 drives the connecting shaft 28 to rotate in the opposite direction. The connecting shaft 28 then pays out the first pull rope 22 mounted on its outer surface, so that the two second pull ropes 24 connected to the upper ends of the first pull rope 22 pay out the two support members 9. The two support members 9 are supported by the elastic support force of the arc spring 20 arranged on the inner side, and rotate outward to expand, thereby effectively supporting the middle of the inner side of the aluminum alloy casting 10.

[0035] The rear side of the movable base 26 is fixedly connected to the telescopic ends of a first telescopic cylinder 29 and a guide rod 30. The rear ends of the first telescopic cylinder 29 and the guide rod 30 are fixedly mounted to the rear side of the movable mold base 4 via a fixing member 31. When the first telescopic cylinder 29 and the second telescopic cylinder 34 are activated, the first telescopic cylinder 29 drives the sliding rod 8 and the two supporting members 9 provided on the outside of the sliding rod 8 to move forward to the middle of the inner side of the aluminum alloy casting 10.

[0036] like Figure 5 、 Figure 6 、 Figure 9 and Figure 10As shown, the interior and upper end of the sliding rod 8 are jointly provided with an end face cooling mechanism, and the end face cooling mechanism includes a moving box 11 and a fixed box 41, the moving box 11 and the fixed box 41 are slidably arranged on the inner side of the moving opening 7, and the inner sides of the moving box 11 and the fixed box 41 are respectively provided with a ring array of outward inclined air outlet holes 12, and the end face cooling mechanism also includes a moving rod 32, one end of the moving rod 32 is fixedly connected to the middle of the rear side of the moving box 11, and the outer surface of the moving rod 32 slides with the interior of the sliding rod 8 near the upper end, and the rear side of the moving box 11 is fixedly connected with a ventilation rod 33, and the outer surface of the sliding rod 8 is fixedly sleeved with a fixed box 41 near the middle, and the inner side of the fixed box 41 is fixedly connected with a telescopic tube 38, and the upper end of the telescopic tube 38 passes through the interior of the sliding rod 8 and is fixedly connected to the bottom side of the ventilation rod 33, and the bottom end of the ventilation rod 33 passes through the interior of the moving rod 32, the mounting seat 25 and the moving seat 26 in sequence and is fixedly connected to the extension of the second telescopic cylinder 34 The second telescopic cylinder 34 is fixedly mounted on the outer surface of the second telescopic cylinder 34 and near the rear side thereof, and the upper end of the sliding frame 35 is fixedly connected to the bottom end of the ventilation rod 33. The rear end of the second telescopic cylinder 34 is fixedly mounted on the rear side of the movable seat 26 through the mounting bracket 36. One side of the ventilation rod 33 and near the bottom end thereof is fixedly connected to the ventilation hose 37. The second telescopic cylinder 34 is then started to drive the ventilation rod 33 and the movable box 11 connected to the front end of the ventilation rod 33 to move forward to move out of the interior of the aluminum alloy casting 10. At the same time, the air outlet 12 opened on one side of the movable box 11 faces the other end face of the aluminum alloy casting 10; the cold air is transported to the interior of the ventilation rod 33 through the ventilation hose 37, and the cold air is then transported to the telescopic tube 38 and the movable box 11 respectively through the ventilation rod 33. The telescopic tube 38 then transports the cold air to the fixed box 41. The air outlet 12 set at the inner side of the movable box 11 and the fixed box 41 then performs a rapid blowing of cold air to cool down the two end faces of the aluminum alloy casting 10.

[0037] A control unit is fixedly installed on the rear side of the movable mold base 4. When the aluminum alloy casting 10 is moved out of the fixed mold 5 and needs support, the control unit controls the first telescopic cylinder 29 to cooperate with the drive motor 40, so that the two support members 9 move and expand to the inner side of the aluminum alloy casting 10 for effective support and demolding. At the same time, the control unit controls the first telescopic cylinder 29 to move the air outlet 12 opened on one side of the fixed box 41 to the end face close to one side of the aluminum alloy casting 10. The control unit controls the second telescopic cylinder 34 to drive the mobile box 11 to move out of the inner side of the aluminum alloy casting 10. At the same time, the air outlet 12 opened on one side of the mobile box 11 faces the other side end face of the aluminum alloy casting 10, so that the fixed box 41 and the mobile box 11 can quickly blow cold air to cool down the end faces on both sides of the aluminum alloy casting 10.

[0038] During use, aluminum alloy liquid is pressure-injected into the fixed die casting cavity in the fixed mold 5 and the movable die casting cavity in the movable mold 6 through the injection pipe 15. The aluminum alloy liquid is die-cast to become an aluminum alloy casting 10. After subsequent cooling and demoulding, the servo motor 39 is started. The servo motor 39 drives the screw rod 13 to rotate, and the screw rod 13 then drives the movable mold base 4 and the movable mold 6 to move to one side until the movable die casting cavity is separated from one side of the aluminum alloy casting 10. At the same time, the first telescopic cylinder 29 and the second telescopic cylinder 34 are started. The first telescopic cylinder 29 drives the sliding rod 8 and the two support members 9 arranged on the outside of the sliding rod 8 to move forward to the middle of the inner side of the aluminum alloy casting 10. At the same time, the fixed box 41 set in the middle of the outer surface of the sliding rod 8 is moved out of the interior of the movable die casting cavity and close to the aluminum alloy. On one side of the aluminum casting 10, and the air outlet 12 opened on one side of the fixing box 41 faces one end surface of the aluminum alloy casting 10, and then the driving motor 40 is started, and the driving motor 40 drives the connecting shaft 28 to rotate in the opposite direction, and the connecting shaft 28 then performs a pay-off operation on the first pull rope 22 set on its outer surface, so that the two second pull ropes 24 connected to the upper end of the first pull rope 22 perform a pay-off operation on the two support members 9. The two support members 9 are supported by the elastic support force of the arc spring 20 provided on the inner side, and rotate outward to expand, thereby effectively supporting the inner middle of the aluminum alloy casting 10. After that, the first telescopic cylinder 29 is started again, and the first telescopic cylinder 29 drives the sliding rod 8 and the support member 9 on the sliding rod 8 to drive the aluminum alloy casting 10 to move out of the fixed die casting cavity;

[0039] Afterwards, the second telescopic cylinder 34 is started to drive the ventilation rod 33 and the mobile box 11 connected to the front end of the ventilation rod 33 to move forward to move out of the interior of the aluminum alloy casting 10, and at the same time, the air outlet 12 opened on one side of the mobile box 11 faces the other end face of the aluminum alloy casting 10; cold air is transported to the interior of the ventilation rod 33 through the ventilation hose 37, and the cold air is then transported to the telescopic tube 38 and the mobile box 11 respectively through the ventilation rod 33, and the telescopic tube 38 then transports the cold air to the fixed box 41, and the air outlet 12 set on the inner side of the mobile box 11 and the fixed box 41 then performs a rapid blowing of cold air to cool down the two end faces of the aluminum alloy casting 10. When the subsequent manipulator picks up the aluminum alloy casting 10, it only picks up the two end parts of the aluminum alloy casting 10 that have been rapidly cooled, thereby reducing to a certain extent the direct contact between the manipulator and the surface of the aluminum alloy casting 10 with a higher temperature, and the damage caused to the surface coating of the manipulator accessories.
