As shown in fig. 3, when the workpiece is removed from the mold, the retainer plate 31 needs to be moved toward the mold so that the suction cups 33 contact the workpiece, which tends to cause the accommodating tube 21 to collide with the mold. Therefore, the fixed plate 11 is connected with a material taking cylinder 34 for driving the material taking plate 31 to move along the axis of the accommodating tube 21, and a piston rod of the material taking cylinder 34 is fixed with the end surface of the material taking plate 31 far away from the suction cup 33 by using a bolt. When utilizing extracting mechanism 3 to take out the work piece from the mould in, utilize and get material cylinder 34 to promote to get flitch 31 and remove towards the mould, make sucking disc 33 and work piece butt, later get material cylinder 34 and drive the work piece and remove towards the direction of keeping away from the mould, make work piece and mould break away from the connection, no longer need make base 1 and the whole mould of getting flitch 31 remove towards the mould at this moment in getting the material in-process, hold the difficult and mould production collision of pipe 21 when getting the material.
As shown in fig. 1 and fig. 3, since the material taking plate 31 is located at the lower end of the base 1 when taking the material and embedding the embedded nut, the base 1 and the material taking plate 31 are required to move downward when finishing taking the material and embedding the embedded nut, and the position of the mold is low, so that the situation that the material taking plate 31 collides with the injection molding machine is likely to occur. Therefore, the base 1 is hinged with the rotating plate 35 at a position close to the material taking plate 31, one end of the rotating plate 35 far away from the fixed plate 11 is connected with the connecting plate 352 through a bolt, and the cylinder body of the material taking cylinder 34 is fixed on the end face of the connecting plate 352 far away from the rotating plate 35 through a bolt.

The end face, far away from the mounting plate 13, of the fixed plate 11 is provided with two rotating cylinders 36 for driving the rotating plate 35 to rotate, the cylinder bodies of the rotating cylinders 36 are hinged to the position, far away from the rotating plate 35, of the fixed plate 11, the position, far away from the material taking plate 31 and close to the fixed plate 11, of the rotating plate 35 is fixedly connected with two rotating seats 351 through bolts, and the piston rods of the rotating cylinders 36 are hinged to the positions, far away from the rotating plate 35, of the rotating seats 351 respectively. After the workpiece is taken out from the mold by the material taking mechanism 3, the piston rod of the rotary cylinder 36 is contracted to rotate the material taking plate 31 to be perpendicular to the fixed plate 11, and at this time, the material taking plate 31 is not easy to collide with the injection molding machine when the base 1 moves downward.
As shown in fig. 3, when the workpiece is taken out of the mold and moved to the outside of the injection molding machine, the workpiece needs to be separated from the suction cup 33, and when the vacuum pump stops sucking air into the suction cup 33, the air in the suction cup 33 is not communicated with the outside and still has a negative pressure, and at this time, the workpiece cannot be directly separated from the suction cup 33, and the workpiece needs to be manually moved to separate the suction cup 33 from the workpiece. Therefore, the end face, far away from the suction cup 33, of the material taking plate 31 is connected with a blanking cylinder 37 for driving the workpiece to be separated from the suction cup 33, the cylinder body of the blanking cylinder 37 is connected with the cylinder body of the material taking cylinder 34 through a bolt, the piston rod of the blanking cylinder 37 penetrates through the material taking plate 31 and is connected with a blanking block 371 through a bolt, and the end face, far away from the blanking cylinder 37, of the blanking block 371 can be abutted to the workpiece. At this time, when the workpiece needs to be separated from the suction cup 33, the piston rod of the blanking cylinder 37 pushes the blanking block 371 to move towards the direction away from the material taking plate 31, so that the workpiece is separated from the suction cup 33, and at this time, the workpiece does not need to be separated from the suction cup 33 manually, and the labor intensity of workers is reduced.
As shown in fig. 3, since the shape of different workpieces is different, the suction cups 33 need to be attached to the flat surface of the workpiece, and the positions of the suction cups 33 distributed on the surface of the material taking plate 31 need to be adjusted. Therefore, a plurality of waist-shaped grooves 313 penetrate through the end surface of the material taking plate 31 close to the suction cup 33, the waist-shaped grooves 313 are parallel or vertical to each other, and the suction pipes 32 penetrate through the waist-shaped grooves 313 and slide along the length direction of the waist-shaped grooves 313. Each suction pipe 32 is in threaded connection with two limiting nuts 321 for limiting the positions of the suction pipes 32, and the two limiting nuts 321 connected with the same suction pipe 32 clamp the material taking plate 31 simultaneously. The position of the suction pipe 32 can be adjusted by arranging the waist-shaped groove 313, so that workpieces in different shapes can be sucked and moved, and the application range of the material taking mechanism 3 is wider.
As shown in fig. 2, when the position-limiting member 221 is not in contact with the embedded nut, it still receives the elastic force applied by the elastic member 222 toward the axis of the accommodating tube 21, and falls into the accommodating tube 21. Therefore, the diameter of the limiting hole 211 close to the axis of the accommodating tube 21 is smaller than the diameter of the limiting piece 221, and at this time, when the limiting piece 221 is subjected to the elastic force applied by the elastic piece 222 towards the axis of the accommodating tube 21, the limiting piece 221 cannot fall into the accommodating tube 21, so that the using process of the limiting mechanism 22 is more stable.
As shown in fig. 1, when the push-out rod 23 is used to push out the nut block from the containing pipe 21, the push-out rod 23 still needs to be pushed manually to move, which is troublesome. Therefore, the end face, far away from the accommodating tube 21, of the mounting plate 13 is fixed with a plurality of mounting frames 14 through bolts, the end face, far away from the mounting plate 13, of the mounting frame 14 is connected with an ejection cylinder 15 for pushing the ejection rod 23 to move, the cylinder body of the ejection cylinder 15 is fixedly connected with the mounting frame 14 through bolts, and the piston rod of the ejection cylinder penetrates through the mounting frame 14 and is connected with one end, far away from the accommodating tube 21, of the ejection rod 23 through bolts. The ejection cylinder 15 is used for pushing the ejection rod 23 to move, and at the moment, the ejection rod 23 does not need to be pushed manually to move, so that the labor intensity of workers is reduced.
As shown in fig. 2, since the outer wall of the nut is attached to the inner wall of the accommodating tube 21, if the axes of the nut and the accommodating tube are not overlapped when the nut is placed on the placing rod 43, the nut will abut against the end surface of the accommodating tube 21 away from the mounting plate 13, and the nut cannot be placed in the accommodating tube 21. Therefore, the edge of one end of the inner wall of the accommodating tube 21, which is far away from the mounting plate 13, is provided with an accommodating wedge-shaped surface 212, and one end of the accommodating wedge-shaped surface 212, which is far away from the axis of the accommodating groove, inclines towards the mounting plate 132. The movement of the nut is guided by the accommodating wedge-shaped surface 212, so that the nut is not easy to abut against the end surface of the accommodating tube 21 far away from the mounting plate 13 when entering the accommodating tube 21, and the process of putting the nut into the accommodating tube 21 is more convenient.
As shown in fig. 1 and 4, when the embedded nuts are placed in the accommodating tube 21, the nuts need to be manually placed one by one, and at the moment, the mold needs to stop working for a period of time, so that the production efficiency of the product is reduced. Therefore, the placing mechanism 4 for placing the embedded nuts is further arranged, and the placing mechanism 4 comprises a fixing frame 41 arranged on the ground, a placing frame 42 sliding on the upper end of the fixing frame 41 and a placing rod 43 for placing the embedded nuts.
