[0030] like Figure 1-6As shown, the present invention provides a locking mold protection device for a vertical injection molding machine for data line processing, including a mounting shell 1. By setting the mounting shell 1, both sides of the mounting shell 1 are provided with assembly holes, and then the position of the mounting shell 1 can be fixed by inserting bolts into the assembly holes. The upper surface of the mounting shell 1 is fixedly connected to the lower surface of the lower mold 2, and the upper surface of the mounting shell 1 is fixedly connected to the bottom end of the injection molding mechanism 3. The outer surface of the injection molding mechanism 3 is provided with two clamping plates 9, and the two clamping plates 9 are respectively arranged in one of the intervals of the two limit plates 4.

The limiting support point and the limiting plate 4 are provided with a plurality of intervals. An alarm 8 is provided on one side of the limiting plate 4, and a second switch 20 is provided on the lower surface of the limiting plate 4. By setting the second switch 20 and the alarm 8, the second switch 20 can control the alarm 8 to make an audible and visual alarm, so that the staff can discover and deal with it in time, avoiding the problem that the staff are unaware and cause the upper mold 31 to fall directly and injure the staff. The lower surface of the limiting plate 4 is fixedly connected to the top of the two elastic structures 6. By setting the elastic structure 6, the elastic structure 6 can support the limiting plate 4. The bottom ends of the two elastic structures 6 are fixedly connected to the upper surface of the I-plate 18.

[0031] The upper surface of the I-type plate 18 is fixedly connected to the bottom end of the touch rod 19. By providing the touch rod 19, the top of the touch rod 19 is convenient for contacting the second switch 20, thereby avoiding the problem that the elastic structure 6 shrinks to the maximum and cannot touch the second switch 20. The lower surface of the I-type plate 18 is fixedly connected to the upper surface of the threaded seat 13. The two threaded seats 13 are both threadedly connected to the outer surface of the screw 11. By providing the screw 11 and the threaded seat 13, the rotation of the screw 11 can drive the threaded seat 13 to move. The outer surface of the screw 11 is provided with two torsion springs 16. By providing the torsion springs 16, the torsion force of the torsion springs 16 can control the reverse rotation of the screw 11, thereby facilitating the control of the two threaded seats 13 to move closer to each other. The middle part of the outer surface of the screw 11 is fixedly connected to the inner surface of the gear 15, and the gear 15 is engaged with the control structure 5. The control structure 5 is provided inside the mounting shell 1. The first switch 14 is provided on the rear side of the inner wall of the mounting shell 1. By providing the first switch 14, the start of the lifting mechanism 32 can be controlled by the first switch 14.

[0032] like Figure 2 and Figure 6As shown, the injection molding mechanism 3 includes two lifting mechanisms 32. By setting the lifting mechanisms 32, the lifting mechanisms 32 can control the up and down movement state of the upper mold 31. The bottom ends of the two lifting structures are fixedly connected to the upper surface of the upper mold 31. By setting the upper mold 31 and the lower mold 2, and the top of the upper mold 31 is provided with an injection port, it is convenient to add injection molding material, and the upper mold 31 and the lower mold 2 are provided with multiple mold cavities, which is convenient for batch injection molding of data line terminals and improves injection molding efficiency. The two sides of the outer surface of the upper mold 31 are respectively fixedly connected to the opposite surfaces of the two card plates 9. The lifting mechanism 32 is fixedly installed inside the fixing seat 33. By setting the fixing seat 33, the fixing seat 33 can fix the lifting mechanism 32 to prevent the lifting mechanism 32 from falling. The lower surface of 33 is fixedly connected to the top of the two support columns 34. By setting the support columns 34, the support columns 34 can fix the position of the fixed seat 33, and at the same time it is convenient to set the height of the lifting mechanism 32. At the same time, the support columns 34 can guide the card plate 9, so that the card plate 9 can slide up and down smoothly. The bottom ends of the two support columns 34 are fixedly connected to the upper surface of the mounting shell 1. The lower sides of the four support columns 34 are fixedly mounted inside the lower mold 2. The card plate 9 is slidably connected to the outer surfaces of the two support columns 34. Two through holes 7 are provided on both sides of the upper surface of the mounting shell 1. By setting the I-type plate 18 and the through hole 7, the through hole 7 can provide a movable space for the I-type plate 18, so that the I-type plate 18 can slide smoothly. The two I-type plates 18 are slidably connected to the inside of the two through holes 7 respectively.

[0033] like Figure 4 、 Figure 5 and Figure 6As shown, the control structure 5 includes a support sleeve 52, which is fixedly mounted on the front side of the outer surface of the mounting shell 1. By setting the support sleeve 52, the support sleeve 52 can guide the handle 53, so that the handle 53 can slide smoothly inside the support sleeve 52. The handle 53 is connected to the inner sliding of the support sleeve 52. By setting the handle 53, the T-shaped structure of the handle 53 can provide an operating point for the staff, thereby facilitating the staff to control the movement of the gear rod 51 from the outside. The rear side of the outer surface of the handle 53 is fixedly connected to the front end of the outer surface of the gear rod 51. By setting the gear rod 51 and the gear 15, the gear rod 51 can be moved. The control gear 15 rotates, and then the screw 11 can be controlled to rotate through the meshing transmission of the gear rod 51 and the gear 15. The gear rod 51 is meshed with the gear 15, and the outer surface of the screw 11 is fixedly connected to the inner surface of the two circular sleeves 17 respectively. By providing the circular sleeve 17, the circular sleeve 17 can provide a fixed point for one end of the torsion spring 16. The opposite surfaces of the two circular sleeves 17 are fixedly connected to one end of the two torsion springs 16 respectively. The front and rear sides of the inner wall of the mounting shell 1 are fixedly connected to the front and rear sides of the outer surface of the two fixing plates 10 respectively. By providing the fixing plate 10, the fixing plate 10 can support and fix the bearing 12. The two fixed Bearings 12 are fixedly installed on the left and right sides of the interior of the fixed plate 10 and the outer surface of the mounting shell 1. By setting the bearings 12, the bearings 12 can support the screw 11. At the same time, the bearings 12 can ensure the smooth sliding of the screw 11. The screw 11 is rotatably connected to the inside of the four bearings 12, and the opposite back surfaces of two bearings 12 are respectively fixedly connected to the other end of the torsion spring 16. The elastic structure 6 includes a telescopic rod 61. By setting the telescopic rod 61, the telescopic rod 61 can guide the spring 62 to ensure that the spring 62 can be smoothly extended and retracted up and down. The top of the telescopic rod 61 is fixedly connected to the lower surface of the limit plate 4, and the bottom end of the telescopic rod 61 is fixedly connected to the I-type plate 18. The upper surface is fixedly connected, and the outer surface of the telescopic rod 61 is sleeved with a spring 62. By setting the spring 62, the elastic force of the spring 62 can not only support the limit plate 4, but also when the limit plate 4 applies gravity downward, the spring 62 can be deformed, so that the touch rod 19 can smoothly touch the second switch 20. The top of the spring 62 is fixedly connected to the lower surface of the limit plate 4, and the bottom end of the spring 62 is fixedly connected to the upper surface of the I-type plate 18. The threads on both sides of the outer surface of the screw 11 are set oppositely. By setting the threads on both sides of the screw 11 oppositely, the rotation of the screw 11 can realize the control of the two threaded seats 13 to move closer to or away from each other.

[0034] Working principle of the present invention:

[0035] S1. First, push the handle 53 to move, so that the handle 53 slides inside the support sleeve 52, so that the handle 53 pushes the gear rod 51 to move, so that the gear rod 51 and the gear 15 are meshed and transmitted, so that the gear 15 drives the screw rod 11 to rotate, so that the torsion spring 16 is twisted, so that the screw rod 11 drives the two threaded seats 13 to move away from each other, so that the two threaded seats 13 drive the two I-shaped plates 18 to slide in the two through holes 7, so that the two I-shaped plates 18 move away from each other, so that the I-shaped plates 18 drive the limit plate 4 to move through the elastic structure 6, so that the interval between the limit plate 4 and the clamping plate 9 is separated;

[0036] S2. At this time, the gear rod 51 moves backward and touches the first switch 14, so that the first switch 14 controls the lifting mechanism 32 to operate, so that the lifting mechanism 32 controls the upper mold 31 to move downward, so that the upper mold 31 is pressed downward against the lower mold 2, and then the injection molding material is injected through the injection port at the top of the upper mold 31. At this time, the injection molding material fills the mold cavities of the upper mold 31 and the lower mold 2 for injection molding, and the handle 53 is released, so that the torsion spring 16 can drive the screw 11 to reverse and reset, so that the screw 11 drives the two threaded seats 13 to move closer to each other, so that the two threaded seats 13 drive the two I-type plates 18 to move closer to each other, so that the two limit plates 4 move closer to each other, and then the two clamping plates 9 are respectively clamped into the two gaps of the limit plates 4;

[0037] When the upper mold 31 is in the state of being moved upward, the upper mold 31 and the lower mold 2 are separated. When the upper mold 31 reaches the appropriate height, the handle 53 is released, and the torsion spring 16 drives the screw 11 to reverse the movement, so that the two limit plates 4 are close to each other, so that the two limit plates 9 are respectively stuck in the gap between the two limit plates 4, and then the staff can take the material from the bottom. If the lifting mechanism 32 is damaged during the material taking process and the upper mold 31 loses its supporting force, the gravity of the upper mold 31 acts on the card plate 9, so that the limit plate 4 provides supporting force, so that the limit plate 4 squeezes the elastic structure 6 downward to produce deformation, so that the touch rod 19 touches the second switch 20. At this time, the second switch 20 controls the alarm 8 to sound an alarm, so that the staff can know in time that the upper mold 31 has fallen off.
