[0019] Furthermore, a card slot 8 is provided on the upper side wall of the base 1, one side of the base 1 is fixedly connected to the support frame plate 4, the upper end of the support frame plate 4 is fixedly connected to the cylinder 5, one end of the side wall of the support frame plate 4 is fixedly connected to a fixing rod 65, and the lower end of the fixing rod 65 is fixedly connected to the pressure sensor 64; the push assembly 2 also includes a push rod 21 and a telescopic spring 22, one end of the push rod 21 is fixedly connected to the push plate 27, the other end of the push rod 21 passes through the side wall of the support frame plate 4 and is fixedly connected to the baffle 25, the telescopic spring 22 is sleeved on the outer wall of the push rod 21, and the two ends of the telescopic spring 22 are respectively fixedly connected to the side wall of the push plate 27 and the side wall of the baffle 25, and the push plate 27 is slidably connected to the base 1; an electromagnetic block 23 is provided on one side of the baffle 25 And the magnetic block 26, the magnetic block 26 is fixedly connected to the side wall of the baffle 25, the electromagnetic block 23 is fixedly connected to the side wall of the support frame plate 4, and buffer columns 24 are provided on both sides of the electromagnetic block 23, and the buffer columns 24 are fixedly connected to the side walls of the support frame plate 4; the reset assembly 3 includes a vertical rod 31 and a reset spring 32, the lower end of the vertical rod 31 is fixedly connected to the base 1, and the upper end of the vertical rod 31 is fixedly connected to the limiting plate 33; the two ends of the lower mold 7 are fixedly connected with ear plates 71, and the ear plates 71 are slidably connected to the vertical rod 31, and the lower side wall of the lower mold 7 is fixedly connected with a sealing strip 72 matched with the card groove 8; the reset spring 32 is sleeved on the outer wall of the vertical rod 31, and the two ends of the reset spring 32 are respectively fixedly connected to the side walls of the limiting plate 33 and the side walls of the ear plate 71.

[0020] It should be noted that: in the process of injection molding the power cord, the cylinder 5 is first started to drive the moving plate 61 to move downward. In the initial state, the moving plate 61 squeezes the pressure sensor 64, and the pressure sensor 64 is electrically connected to the electromagnetic block 23. Therefore, when the moving plate 61 moves downward and separates from the pressure sensor 64, the pressure sensor 64 is no longer squeezed. At this time, the electromagnetic block 23 starts to be energized, and the magnetism of the end of the electromagnetic block 23 away from the support frame plate 4 after charging is the same as the magnetism of the end of the magnetic block 26 close to the support frame plate 4. Therefore, after the electromagnetic block 23 is energized, the baffle 25 will quickly move away from the support frame due to the effect of like-charge repulsion. The plate 4 is moved downwards by the baffle plate 25, and the push rod 21 is driven to slide on the support frame plate 4, and the telescopic spring 22 is compressed. At this time, the push plate 27 is also moving rapidly to the side of the support frame plate 4, and no longer affects the downward movement of the lower mold 7. In the process of the moving plate 61 moving downwards, the upper mold 63 is driven to move synchronously, and after the upper mold 63 contacts the lower mold 7, the lower mold 7 is gradually squeezed and moved downwards. In this process, the lower mold 7 can not only limit the moving position of the lower mold 7 through the sliding of the ear plate 71 on the vertical rod 31 and the stretching of the reset spring 32, but also ensure the stability during movement, thereby reducing In the case of shaking, the sealing strip 72 under the lower mold 7 is finally inserted into the card slot 8 to achieve the sealing effect of the bottom end of the lower mold 7, and the upper end of the lower mold 7 is sealed by the upper mold 63. At this time, injection molding can be started into the mold cavity through the injection tube connected to the upper mold 63 and the movable plate 61. After the injection molding is completed, the movable plate 61 is driven upward by the cylinder 5, which will first drive the upper mold 63 and the lower mold 7 to move up one end distance synchronously. After the lower mold 7 is returned to its position by the reset spring 32, the upper mold 63 continues to move up. When the movable plate 61 squeezes the pressure sensor 64, the cylinder 5 stops working, and the electromagnetic block 23 is disconnected at this time. The magnetic block 26 loses its force, and the telescopic spring 22 drives the push plate 27 away from the support frame plate 4 through elastic recovery, thereby pushing the finished power cord that falls on the surface of the base 1 down. In addition, a collection frame can be set on one side of the base 1 to directly collect the pushed-down power cord, reduce manual picking, and improve work efficiency. In order to avoid the electromagnetic block 23 and the magnetic block 26 from colliding with each other during the rebound process of the telescopic spring 22, the baffle 25 can be buffered by the buffer column 24 to avoid the contact between the magnetic block 26 and the electromagnetic block 23, thereby ensuring the use effect of both. The buffer column 24 can be made of rubber material, which can effectively absorb external impact force.

[0021] Reference Figure 7-Figure 8, further; the upper end of the movable plate 61 is fixedly connected to the cylinder 5, the lower end of the movable plate 61 is fixedly connected to the upper mold 63, the upper mold 63 is located directly above the lower mold 7, the upper side wall of the movable plate 61 is fixedly connected to the telescopic airbag 62, the upper end of the telescopic airbag 62 is fixedly connected to the support frame plate 4, and a blowing slot 66 is opened between the movable plate 61 and the upper mold 63, and one end of the blowing slot 66 is connected to the telescopic airbag 62.

[0022] It should be noted that: during the downward movement of the movable plate 61, the telescopic airbag 62 is stretched, and the outside air enters the interior of the telescopic airbag 62 through the blowing slot 66 for storage. After the injection molding is completed, the movable plate 61 moves upward, and the telescopic airbag 62 is squeezed, and the air inside it is compressed. At this time, the compressed gas is discharged from the blowing slot 66, and then blown into the interior of the lower mold 7, thereby cooling the temperature inside the lower mold 7. At the same time, the impact force generated can effectively promote the falling of the power cord to improve the pushing effect.

[0023] The working principle of the semi-finished power cord injection mold is as follows: in the process of injection molding the power cord, the cylinder 5 is first started to drive the moving plate 61 to move downward. In the initial state, the moving plate 61 squeezes the pressure sensor 64, and the pressure sensor 64 is electrically connected to the electromagnetic block 23. Therefore, when the moving plate 61 moves downward and separates from the pressure sensor 64, the pressure sensor 64 is no longer squeezed. At this time, the electromagnetic block 23 starts to be energized, and after the electromagnetic block 23 is charged, the magnetism of the end away from the support frame plate 4 is the same as the magnetism of the end of the magnetic block 26 close to the support frame plate 4. Therefore, after the electromagnetic block 23 is energized, the baffle will be repelled due to the effect of like charges. 25 quickly moves away from the support frame plate 4, and at the same time, the baffle plate 25 drives the push rod 21 to slide on the support frame plate 4, and the telescopic spring 22 is compressed. At this time, the push plate 27 also moves quickly to the side of the support frame plate 4, and no longer affects the downward movement of the lower mold 7. During the downward movement of the moving plate 61, the upper mold 63 is driven to move synchronously, and after the upper mold 63 contacts the lower mold 7, the lower mold 7 is gradually squeezed and moved downward. In this process, the lower mold 7 can not only limit the moving position of the lower mold 7 through the sliding of the ear plate 71 on the vertical rod 31 and the stretching of the reset spring 32, but also ensure the stability during movement. The sealing strip 72 under the lower mold 7 is finally inserted into the card slot 8 to achieve the sealing effect at the bottom of the lower mold 7, and the upper end of the lower mold 7 is sealed by the upper mold 63. At this time, the injection molding tube connected to the upper mold 63 and the movable plate 61 can be used to start injection molding in the mold cavity. After the injection molding is completed, the movable plate 61 is driven upward by the cylinder 5, which will first drive the upper mold 63 and the lower mold 7 to move up one end distance synchronously. After the lower mold 7 is returned to its position by the reset spring 32, the upper mold 63 continues to move up. When the movable plate 61 squeezes the pressure sensor 64, the cylinder 5 stops working, and at this time the electromagnetic block 23 is powered off, the magnetic block 26 loses its force, and the telescopic spring 22 drives the push plate 27 away from the support frame plate 4 through elastic recovery, thereby pushing the finished power cord that has fallen on the surface of the base 1 down. In addition, a collection frame can be set on one side of the base 1 to directly collect the pushed-down power cord, reduce manual picking, and improve work efficiency. In order to avoid the electromagnetic block 23 and the magnetic block 26 from colliding with each other during the rebound process of the telescopic spring 22, the baffle 25 can be buffered by the buffer column 24 to avoid the contact between the magnetic block 26 and the electromagnetic block 23, thereby ensuring the use effect of both. The buffer column 24 can be made of rubber material, which can effectively absorb external impact force.
