[0014] See also Figures 1 to 7 A casting machine mold turning device is shown, in which a motor 30 is fixedly connected to a frame 1, one end of a first swing arm 10 is connected to an output shaft of the motor 30, and the other end is rotatably connected to a second swing arm 20 via a pin 11, a hook mouth at one end of the second swing arm 20 away from the first swing arm 10 forms a hook-type connection with a columnar ear A1 fixed on the outer side of a groove wall of a casting mold A, a rotating shaft A2 is provided at the bottom of the casting mold A, and a column core of the columnar ear A1, an axis core of the rotating shaft A2, a pin 11, and a rotating axis of the first swing arm 10 are arranged in parallel, when the motor 30 drives the first swing arm 10 to rotate, the casting mold A can be respectively in a casting position with the mold opening facing upward and a dumping position with the mold opening facing downward as the first swing arm 10 and the second swing arm 20 are driven.
[0015] In the above scheme, a blanking area B is provided at the lower side of the casting mold A. Figure 1As shown, a rotating shaft A2 is provided on one side of the bottom of the casting mold A near the blanking area B. When the casting mold A is in the casting position, the opening on the top of the casting mold A is vertically facing upward, and the plate surface of the alloy part M cast in the casting mold A is in a horizontal posture. Figures 5 to 7 As shown, the hook of the second swing arm 20 is first hooked on the cylindrical lug A1 on the outer side of the groove wall of the casting mold A. After the motor 30 drives the first swing arm 10 to rotate, the end of the first swing arm 10 away from the motor 30 drives the second swing arm 20 to move. The hook of the second swing arm 20 rotates around the cylindrical surface of the lug A1 under the movement of the second swing arm 20, and at the same time pulls the mold to rotate around the rotation axis A2, and the casting mold A flips to the dumping position with the mold opening facing downward. At this time, the alloy part M in the mold falls from the opening to the blanking area B below, and the mold flipping is completed. In the above movement process, the casting mold A realizes its own automatic conversion between the casting position and the dumping position with the movement of the first swing arm 10 and the second swing arm 20, and the whole process can be automatically controlled, which frees up the manual labor required for traditional mold flipping, and can prevent workers from being hit by the alloy part M when flipping the mold, and the mold flipping efficiency is higher.
[0016] After the casting machine's mold turning device flips the casting mold A from the casting position to the tipping position to make the alloy part M fall, in order to drive the casting mold A to return from the tipping position to the casting position, the opening width of the hook mouth 21 of the second swing arm 20 facing the side of the support ear A1 is greater than or equal to the diameter of the columnar support ear A1, and a blocking member 22 is provided on the second swing arm 20. When the blocking member 22 is displaced, it is respectively located at a position where it blocks the opening of the hook mouth 21 or avoids the opening of the hook mouth 21. When the blocking member 22 blocks the opening of the hook mouth 21, the column of the support ear A1 is within the hole area enclosed by the blocking member 22 and the hook mouth 21.
[0017] When the mold is turned over, since the movement direction of the support ear A1 is always away from the open direction of the hook mouth 21, the hook mouth 21 does not need to be closed to complete the mold turning action; on the contrary, since the movement direction of the support ear A1 is toward the open direction of the hook mouth 21 when the mold is returned, the support ear A1 will fall off from the hook mouth 21 when the second swing arm 20 moves. Therefore, it is necessary to provide a sealing member 22 that can close the hook mouth 21, so that the support ear A1 is always in the hole area enclosed by the sealing member 22 and the hook mouth 21 during the mold turning and mold returning actions.
[0018] The specific scheme is that the blocking member 22 is in the shape of a rod and is arranged on the side of the second swing arm 20. The end of the blocking member 22 close to the hook opening 21 is in an "L" shape or a crescent shape, and the opening side of the "L" shape or the crescent shape faces the hook opening 21 of the second swing arm 20. The blocking member 22 is driven by the second cylinder 24 fixed on the second swing arm 20 to block or avoid the opening of the hook opening 21. In the above scheme, after the blocking member 22 is driven by the second cylinder 24 to move to the open blocking position of the hook opening 21, the "L"-shaped or crescent-shaped opening at its end and the hook opening 21 together form a hole area for the support ear A1 to be inserted; after the second cylinder 24 drives the blocking member 22 to move to the open avoiding position of the hook opening 21, the first swing arm 10 and the second swing arm 20 are reset.
[0019] Preferably, Figure 2 , 3 As shown, the middle part of the second swing arm 20 is hinged by the pin shaft 11, and a pin connection hole 23 is provided on the end of the second swing arm 20 away from the hook mouth 21. When the pin connection hole 23 is directly opposite to the pin hole 14 on the first swing arm 10, a plug 41 is inserted and connected. The plug 41 is arranged parallel to the pin shaft 11. When the plug 41 is inserted into the pin hole 14 and the pin connection hole 23 at the same time, the posture of the second swing arm 20 relative to the first swing arm 10 can be maintained, so that the motor 30 can drive the hook mouth 21 of the second swing arm 20 to hook or detach from the lug A1 of the casting mold A.
[0020] In a more specific solution, a first cylinder 40 is provided on the first swing arm 10 or the second swing arm 20 , and a piston rod of the first cylinder 40 serves as a latch 41 to be plugged into and matched with the pin connection hole 23 and the pin hole 14 .
[0021] In order to limit the swing angle of the second swing arm 20, the lower end of the arc rod 12 in the shape of a strip whose plate surface is located in the plumb plane is fixedly connected to the frame 1 and its upper end is in a free state, the curvature center of the outer convex edge of the arc rod 12 is located at a coaxial position of the output shaft of the motor 30 or the curvature center of the outer convex edge of the arc rod 12 is close to the output shaft of the motor 30, and the rotation path of the end of the second swing arm 20 away from the hook mouth 21 is coplanar with the arc rod 12. When the second swing arm 20 swings to an angle where its own rod length direction is close to the colinear angle with the rod length direction of the first swing arm 10, the upper end surface of the arc rod 12 abuts against the end of the second swing arm 20 away from the hook mouth 21. After the two abut against each other, the second swing arm 20 is limited, so that it cannot continue to swing around the pin shaft 11 in the direction away from the casting mold A. The matching relationship between the second swing arm 20 and the arc rod 12 can be arranged in the following two preferred schemes: the end of the second swing arm 20 away from the hook mouth 21 and the upper end of the arc rod 12 are located on the same side of the first swing arm 10, or both are inserted into the notch 15 of the end of the first swing arm 10 away from the motor 30.
[0022] In order to limit the swing angle of the first swing arm 10, at least one arc-shaped limit hole 131 concentric with the axis of the output shaft of the motor 30 is provided on the limit plate 13 fixedly connected to the frame 1, and a corresponding retractable convex pin which can be inserted into the arc-shaped limit hole 131 is provided on the arm surface of the first swing arm 10 facing the limit plate 13. When the convex pin of the first swing arm 10 is inserted into the arc-shaped limit hole 131, the swingable angle range of the first swing arm 10 is consistent with the angle corresponding to the arc length of the arc-shaped limit hole 131. After the first swing arm 10 is limited by the arc-shaped limit hole 131, the impact on the casting mold A during the mold turning and returning actions can be reduced. Different limit angles can be adjusted by inserting the convex pin into different arc-shaped limit holes 131, and the limit can be cancelled when the convex pin retracts and disengages from the arc-shaped limit hole 131.
[0023] See also Fig. 9 An alloy plate conveying and stacking system including a casting machine mold turning device is shown, a blanking area B is provided below the casting mold A of the disc casting machine, a casting machine mold turning device is arranged beside the blanking area B, and a pre-stacking plate 50, a stacking robot 60, a drilling and milling machine 70 and a conveying plate chain 80 are respectively provided on the other side of the blanking area B relative to the disc casting machine. The receiving end of the conveying plate chain 80, the drilling and milling machine 70 and the pre-stacking plate 50 are all within the travel range of the mechanical arm 61 of the stacking robot 60, and a weighing and counting mechanism 90 is arranged in the side area of the unloading end of the conveying plate chain 80.
[0024] In the above scheme, the alloy part M falls into the blanking area B after being turned over by the mold turning device of the casting machine. The stacking robot 60 clamps the alloy part M in the blanking area B and stacks it on the pre-stacking tray 50. Then the stacking robot 60 clamps the alloy part M from the pre-stacking tray 50 and transports it to the drilling and milling machine 70 for drilling and removing burrs. After completing the above operations, the stacking robot 60 clamps the alloy part M and places it at the receiving end of the conveyor plate chain 80. It is transported to the weighing and counting mechanism 90 beside its unloading end through the conveyor plate chain 80 for weighing and counting, and finally stacked into the finished product container through the truss mechanism. Through the above integrated technical scheme, the alloy part M is automatically completed from the line, conveyed and stacked.
