[0023] When producing the structural parts of the notebook computer, the staff installed the two-color mold on the injection molding machine. The installation method adopts the existing technology and is not described in detail. When the injection molding of one mold 201 is completed, it is necessary to rotate to another mold 201 position to change the position. The controller sends a signal to start the main control board. After receiving the signal, the main control board starts the driving source in the ejection component 6. The driving source drives the execution end of the ejection component 6 to move upward and drives the vertical rod 7 to rotate, pushing the plug-in block 503 at the terminal of the arc groove 101, so that the plug-in block 503 moves upward. The plug-in block 503 stretches the contraction spring 502 through the lower pressure plate 501 until the plug-in block 503 moves to the top of the arc groove 101. At this time, the telescopic baffle 1012 is extended and located between the top of the execution end of the ejection component 6 and the bottom of the plug-in block 503, and contacts with the first ball 5031; Then the driving source of the ejection assembly 6 works in the reverse direction, so that the execution end moves downward, while the plug-in block 503 does not move downward due to the telescopic baffle 1012, and the vertical rod 7 rotates in the reverse direction to drive the transmission shaft 8 to rotate through the clamping structure, and the transmission shaft 8 drives the shaft rod 1041 to rotate through the transmission structure, so that the shaft rod 1041 drives the turntable 2 to rotate, and the turntable 2 drives the contracted plug-in block 503 to move, and the first ball 5031 is completely moved out of the arc groove 101 under the action of the telescopic baffle 1012 and the first chamfer 1011; Finally, when the plug-in block 503 on the other side moves to the starting end of the arc groove 101 with the rotation of the turntable 2, the contraction spring 502 releases the pressure, so that the plug-in block 503 is inserted into the arc groove 101 and contacts with the pressure sensor 105. The pressure sensor 105 detects the pressure and sends a signal to the main control board, which controls the driving source of the ejection assembly 6 to slow down until it stops, until the plug-in block 503 moves along the arc groove 101 to the terminal, and the side wall of the plug-in block 503 pushes the telescopic baffle 1012 to shrink and encounters resistance after moving to the groove wall. At this time, the driving source stops working, and the positions of the two molds 201 are interchanged to complete the positioning. Therefore, the present application does not need to worry about the refraction of light and the reduction of brightness caused by lubricating oil. The structure can ensure the positioning accuracy of the rotation and the injection molding efficiency of the laptop computer structural parts.

[0024] See also Figure 4-8As shown, a driving cavity 102 is provided inside the lower base 1 below the terminal end of the arc groove 101, and the ejection assembly 6 is arranged in the driving cavity 102. The ejection assembly 6 includes a driving motor 601 arranged in a mounting block 107, and the output end of the driving motor 601 is inserted into the driving cavity 102 and fixed with a rotating shaft 602. A screw rod 603 is installed on the top of the rotating shaft 602 through a magnetic coupler 606. A sleeve 604 is sleeved on the screw rod 603. The top of the sleeve 604 passes through the driving cavity 102 and extends into the arc groove 101. The top of the sleeve 604 matches the plug-in block 503 provided in the plug-in assembly 5. Slide rods 60 are fixed on both sides of the driving cavity 102. 5. A movable plate 6041 is fixed to the outer wall of the bottom end of the sleeve 604. Both ends of the movable plate 6041 are slidably sleeved on the slide bar 605. A cavity 103 is opened inside the lower base 1 on one side of the driving cavity 102. The cavity 103 is connected to the driving cavity 102 through a square through hole. The vertical rod 7 and the transmission shaft 8 are rotatably installed on the bottom and top of the driving cavity 102 respectively. The outer wall of the vertical rod 7 and the outer wall of the rotating shaft 602 are fixed with a first transmission wheel 702. The two first transmission wheels 702 are connected by a first transmission chain 7021. The first transmission chain 7021 slides along the hole wall of the square through hole. The top outer wall of the vertical rod 7 is provided with two telescopic clamping blocks 9. The outer wall of the vertical rod 7 is provided with two upper and lower movable grooves 701, and movable plates 901 are movably installed in the two movable grooves 701. One end of the two clamping blocks 9 is inserted into the movable groove 701 and welded to the movable plate 901. The other side of the two movable plates 901 is provided with a support spring 902. The two ends of the two support springs 902 are respectively fixedly connected to the plate surface of the movable plate 901 and the groove wall of the movable groove 701. The end faces of the two clamping blocks 9 are embedded with second balls 903. The diameter of the transmission shaft 8 is larger than the diameter of the vertical rod 7.

The two second transmission wheels 801 are connected through a second transmission chain 8011, and the second transmission chain 8011 slides along the hole wall of the square through hole.

[0025] When the two molds 201 are rotating, the driving motor 601 in the ejection assembly 6 is working, and its output end drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the screw rod 603 to rotate, and at the same time drives the vertical rod 7 to rotate through the first transmission wheel 702 and the first transmission chain 7021. The screw rod 603 causes the sleeve 604 to move upward under the restriction of the moving plate 6041 and the sliding rod 605. The sleeve 604 that moves upward pushes the first ball 5031, and then pushes the plug-in block 503 to move upward. When the vertical rod 7 rotates in the slot 803, the two clamping blocks 9 will be driven to move, and under the action of the second chamfer 10, the two clamping blocks 9 will move out of the clamping slot 802, and the two clamping blocks 9 will move into the movable slot 701 and push the movable plate 901, the movable plate 901 will squeeze the support spring 902, and the two clamping blocks 9 will move along the slot 803 through the second ball 903 as the vertical rod 7 rotates, thereby preventing the transmission shaft 8 from rotating with the vertical rod 7 when the sleeve 604 moves upward; Then the driving motor 601 works in the reverse direction and drives the rotating shaft 602 to rotate in the reverse direction. At this time, the sleeve 604 follows the rotation of the screw rod 603 and descends, and the vertical rod 7 drives the contracted clamping block 9 to rotate in the reverse direction in the slot 803, so that when the clamping block 9 passes through the clamping slot 802, the supporting spring 902 pushes the movable plate 901 to insert the clamping block 9 into the clamping slot 802, so that the right-angle end of the clamping block 9 and the clamping slot 802 contacts, and as the vertical rod 7 rotates in the reverse direction, the transmission shaft 8 is driven to rotate through the clamping block 9 and the clamping slot 802, and the transmission shaft 8 is driven to rotate through the second transmission wheel 801 and the second transmission sprocket 8011, so that the shaft 1041 drives the turntable 2 to rotate on the lower base 1, and under the action of the magnetic coupler 606, the sleeve 604 will not hinder the rotation of the rotating shaft 602 and the shaft 1041 after it moves down and resets.

[0026] The working principle of the present invention is: When producing the structural parts of the notebook computer, the staff installed the two-color mold on the injection molding machine. The installation method adopts the existing technology and is not described in detail. When the injection molding of one mold 201 is completed, it is necessary to rotate to another mold 201 position to change the position. The controller sends a signal to start the main control board. After receiving the signal, the main control board starts the drive motor 601 in the ejection component 6. The output end drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the screw rod 603 to rotate. At the same time, it also drives the first transmission wheel 702 and the first transmission wheel 703 to rotate. The movable chain 7021 drives the vertical rod 7 to rotate, and the screw rod 603 causes the sleeve 604 to move upward under the restriction of the movable plate 6041 and the sliding rod 605. The upward-moving sleeve 604 pushes the first ball 5031, and then pushes the plug-in block 503 to move upward. The plug-in block 503 stretches the contraction spring 502 through the lower pressure plate 501 until the plug-in block 503 moves to the top of the arc groove 101. At this time, the telescopic baffle 1012 is extended and located between the top of the sleeve 604 and the bottom of the plug-in block 503, and contacts with the first ball 5031. When the vertical rod 7 rotates in the slot 803, the two clamping blocks 9 will be driven to move, and under the action of the second chamfer 10, the two clamping blocks 9 will move out of the clamping slot 802, and the two clamping blocks 9 will move into the movable slot 701 and push the movable plate 901, the movable plate 901 will squeeze the support spring 902, and the two clamping blocks 9 will move along the slot 803 through the second ball 903 as the vertical rod 7 rotates, thereby preventing the transmission shaft 8 from rotating with the vertical rod 7 when the sleeve 604 moves upward; Then the driving motor 601 works in the reverse direction to drive the rotating shaft 602 to rotate in the reverse direction. At this time, the sleeve 604 follows the rotation of the screw rod 603 and descends, and the vertical rod 7 drives the contracted clamping block 9 to rotate in the reverse direction in the slot 803, so that when the clamping block 9 passes through the clamping slot 802, the supporting spring 902 pushes the movable plate 901 to insert the clamping block 9 into the clamping slot 802, so that the right-angle end of the clamping block 9 and the clamping slot 802 contacts, and as the vertical rod 7 rotates in the reverse direction, the transmission shaft 8 is driven to rotate through the clamping block 9 and the clamping slot 802, and the transmission shaft 8 is driven to rotate through the second transmission wheel 801 and the second transmission sprocket 8011, so that the shaft 1041 drives the rotating disk 2 to rotate on the lower base 1, and the rotating disk 2 drives the contracted plug-in block 503 to move, and is completely moved out of the arc slot 101 through the first ball 5031 on the telescopic baffle 1012 and the first chamfer 1011. Finally, when the plug-in block 503 on the other side moves to the starting end of the arc groove 101 with the rotation of the turntable 2, the contraction spring 502 releases the pressure, so that the plug-in block 503 is inserted into the arc groove 101 and contacts with the pressure sensor 105. The pressure sensor 105 detects the pressure and sends a signal to the main control board, which controls the driving source of the ejection component 6 to slow down until it stops, until the plug-in block 503 moves to the terminal along the arc groove 101. The side wall of the plug-in block 503 pushes the telescopic baffle 1012 to contract and receives resistance after moving to the groove wall. At this time, the driving source stops working, and the positions of the two molds 201 are interchanged to complete the positioning.
