The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0055] See also Figures 1 to 8 The utility model provides a multi-station wire injection molding device with automatic reversing positioning, which is used for injection molding structural parts on wires, including an injection molding machine, a sliding base frame 2, a sliding table 3, a wire pay-off frame 4 and a sliding drive mechanism 5. The injection molding machine includes two injection mold blocks 1 arranged opposite to each other up and down, and the two injection mold blocks 1 can be close to or away from each other. The injection mold block 1 has an injection molding cavity for injection molding structural parts on the wire. The sliding table 3 can be installed on the sliding base frame 2 in a straight line sliding manner left and right. The sliding table 3 is provided with a wire pay-off frame positioning position, and the wire pay-off frame 4 is installed on the wire pay-off frame positioning position of the sliding table 3. The wire pay-off frame 4 can clamp multiple wires, and the wires are installed on the wire pay-off frame 4 and straightened in the left and right directions. The sliding drive mechanism 5 drives the sliding table 3 to slide left and right, driving the wire pay-off frame 4 to enter or leave between the two injection mold blocks 1. The injection molding machine, the sliding base frame 2, the sliding table 3, the wire pay-off frame 4 and the sliding drive mechanism 5 can all be existing designs.

[0056] The special feature of the utility model is that it also includes a rotation reversing device, which includes a load mechanism 6, a lifting mechanism 8 and a rotating mechanism 7. The sliding table 3 is provided with a reversing parking position for the sliding table 3 to park. The load mechanism 6 is arranged above the reversing parking position and can be fixedly connected to the pay-off frame 4. The lifting mechanism 8 is connected to the load mechanism 6 by transmission and can drive the load mechanism 6 to rotate horizontally 180°. The rotating mechanism 7 is connected to the load mechanism 6 by transmission and is used to drive the load mechanism 6 to move vertically in a straight line. When the sliding table 3 is parked at the reversing parking position, the center of the pay-off frame 4 is located directly below the rotation axis 71 line of the load mechanism 6.

[0057] The main working principle of the wire multi-station injection molding equipment of the utility model is as follows: before the injection molding work, the sliding table 3 and the wire pay-off frame 4 are located outside the two injection mold blocks 1; after the wire is installed on the wire pay-off frame 4, the wire pay-off frame 4 is square, and during installation, multiple wire pay-off frames 4 are symmetrically distributed on the front and back sides of the center of the wire pay-off frame 4. The sliding drive mechanism 5 drives the sliding table 3 to slide straight to the left toward the injection mold block 1, driving the wire pay-off frame 4 to enter between the two injection mold blocks 1, and using the two injection mold blocks 1 to inject mold on the wire to obtain multiple injection molded structures in the same direction. When there are injection molded structures in the opposite direction on the wire, after completing the injection molding of the injection molded structures in one direction, the sliding table 3 drives the wire pay-off frame 4 to move to the right and stop at the reversing stop position. At this time, the center of the wire pay-off frame 4 is located directly below the axis of horizontal rotation of the load mechanism 6. Then the rotary reversing device starts to work, and the load mechanism 6 is vertically lowered to the specified position through the lifting mechanism 8. The load mechanism 6 is fixedly connected to the pay-off frame 4 by clamping or adsorption, and then the load mechanism 6 is vertically raised for a distance through the lifting mechanism 8, and then the load mechanism 6 is driven by the rotating mechanism 7 to rotate 180° horizontally, and the load mechanism 6 drives the pay-off frame 4 to rotate 180° horizontally, thereby completing the reverse reversing operation of the wire in the pay-off frame 4. Then the lifting mechanism 8 allows the load mechanism 6 to descend vertically, and the pay-off frame 4 is repositioned downward to the pay-off frame positioning position of the sliding platform 3, and the load mechanism 6 releases the pay-off frame 4. Then the pay-off frame 4 is driven by the sliding platform 3 to enter between the two injection mold blocks 1 for injection molding again. Therefore, by setting the rotary reversing device, the direction of the wire in the pay-off frame 4 can be automatically changed to reverse, so that a set of injection molds can be used to realize the injection molding of injection molding structural parts with opposite directions on the wire, saving mold costs, and no need to re-clamp the wire during the injection molding process, saving employees' clamping time, thereby improving work efficiency.

[0058] In this embodiment, as a preferred design, the wire multi-station injection molding equipment includes a control system, and the control system can preferably use a PLC controller. The control system is connected to the sliding drive mechanism 5 to control the movement of the sliding drive mechanism 5. The control system is also connected to the load mechanism 6, the lifting mechanism 8 and the rotating mechanism 7 of the rotary reversing device to control the clamping, lifting and rotating movements of the rotary reversing device. In this way, by setting the corresponding control program in the control system, the injection molding work of the entire wire multi-station injection molding equipment and the reversing work of the wire pay-off frame 4 can be automatically controlled by the control system.

[0059] In this embodiment, see Figure 1 , Figure 5 and Figure 6 As a preferred design, the load mechanism 6 of the rotary reversing device includes a clamping frame 61 and an electromagnet 62 mounted on the clamping frame 61. The electromagnet 62 can be magnetically fixed on the pay-off frame 4 when powered on. The control mechanism controls the power on and off of the electromagnet 62, thereby controlling the load mechanism 6 to be fixedly connected to the pay-off frame 4, or to put down the pay-off frame 4. The method of using the electromagnet 62 to magnetically fix the pay-off frame 4 is convenient and quick to operate, and only needs to contact the upper surface of the pay-off frame 4. Among them, the number of electromagnets 62 is set to be multiple, and the outer side of the pay-off frame 4 has a square frame. The electromagnet 62 is adsorbed at different positions of the square frame of the pay-off frame 4, thereby ensuring the stability of the pay-off frame 4. In other embodiments, the load mechanism 6 can also adopt other structural forms and be fixedly connected to the pay-off frame 4 by other methods such as clamping.

[0060] In this embodiment, see Figure 1 , Figure 5 and Figure 6As a preferred design, the load mechanism 6 also includes an elastic buffer assembly 63 installed on the clamping frame 61, and the electromagnet 62 is installed at the bottom of the elastic buffer assembly 63, wherein the elastic buffer assembly 63 includes an upper connecting plate 631, a lower connecting plate 632, a guide column 633 and a buffer spring 634, the upper connecting plate 631 is fixedly connected to the clamping frame 61, the upper end of the guide column 633 is fixedly connected to the upper connecting plate 631, and the lower end passes through the guide through hole on the lower connecting plate 632, the buffer spring 634 is sleeved on the guide column 633, and the upper and lower ends of the buffer spring 634 are respectively connected to the upper connecting plate 631 and the lower connecting plate 632, and the electromagnet 62 is fixed to the bottom of the lower connecting plate 632. When the lifting mechanism 8 drives the load mechanism 6 to descend, the electromagnet 62 first contacts the pay-off frame 4, and the electromagnet 62 is subjected to upward pressure, and moves a short distance upward relative to the upper connecting plate 631 together with the lower connecting plate 632, and the buffer spring 634 is compressed. By providing the elastic buffer component 63, on the one hand, a buffering effect is played to avoid damage caused by a hard collision between the pay-off frame 4 and the electromagnet 62, and at the same time, a certain contact pressure can be ensured between the electromagnet 62 and the pay-off frame 4. In other embodiments, the elastic buffer component 63 can also adopt other structural forms.

[0061] In this embodiment, see Figure 5 , Figure 7 and Figure 8 As a preferred design, the lifting mechanism 8 of the rotary reversing device includes a fixed seat frame 81, a lifting frame 82 and a lifting drive assembly. The fixed seat frame 81 is fixedly arranged at the positioning position of the wire pay-off frame of the sliding base frame 2. The lifting frame 82 is installed on the fixed seat frame 81 and can move vertically linearly. The lifting drive assembly is installed on the fixed seat frame 81 and connected to the lifting frame 82. The lifting mechanism 8 and the rotating mechanism 7 are both installed on the lifting frame 82 and are lifted and lowered synchronously with the lifting frame 82. The lifting drive assembly includes a vertically arranged telescopic power cylinder 83. The telescopic power cylinder 83 can be an air cylinder, an oil cylinder or an electric cylinder. The piston rod of the telescopic power cylinder 83 is connected to the lifting frame 82. Two telescopic power cylinders 83 are arranged, which are respectively connected to the front and rear sides of the lifting frame 82. The lifting frame 82 is driven to move up and down by the telescopic movement of the piston rod of the telescopic power cylinder 83, thereby driving the lifting mechanism 8 and the rotating mechanism 7 thereon to move vertically. Furthermore, the lifting mechanism 8 also includes a vertical guide rail 84 fixedly mounted on the fixed seat frame 81 and a vertical slider 85 mounted on the vertical guide rail 84 . The vertical slider 85 is fixedly connected to the lifting frame 82 . The vertical slider 85 slides vertically and linearly on the vertical guide rail 84 to stably guide the movement of the lifting frame 82 .

[0062] In this embodiment, see Figure 5 , Figure 7 and Figure 8As a preferred design, the rotating mechanism 7 includes a rotating shaft 71, a rotating motor 73, and a transmission belt assembly 72 connecting the rotating shaft 71 and the rotating motor 73. The transmission belt assembly 72 is a conventional structure, including two pulleys and a belt connecting the two pulleys, and the pulleys are respectively connected to the output shaft of the rotating motor 73 and the rotating shaft 71. The rotating shaft 71 is vertically arranged and rotatably installed in the lifting frame 82, and the load mechanism 6 is fixedly installed at the lower end of the rotating shaft 71; when the sliding platform 3 is parked at the reversing parking position, the center of the pay-off frame 4 is located directly below the axis of the rotating shaft 71. The rotating motor 73 drives the rotating shaft 71 to rotate through the transmission belt assembly 72, and the rotating shaft 71 drives the load mechanism 6 to rotate. In this way, the 180° rotation of the product pay-off frame 4 can be well achieved, and the axis of the horizontal rotation of the pay-off frame 4 is stable.

[0063] As a preferred design, in this embodiment, see Figure 1 and Figure 4 The sliding drive mechanism 5 includes a conveyor belt 51 extending in the left-right direction, a transmission wheel 52 driving the conveyor belt 51 to move, and a stepper motor 53 driving the transmission wheel 52 to rotate. The sliding platform 3 is fixed to the conveyor belt 51. The stepper motor 53 drives the conveyor belt 51 to move left and right, thereby driving the sliding platform 3 to move left and right in a straight line. With the above design, the conveyor belt 51 can make the sliding platform 3 have a large moving stroke, and the stepper motor 53 can well control the displacement of the sliding platform 3, so that it can be well parked at the reversing parking position, and well positioned and parked in the injection mold block 1 of the injection molding machine.

[0064] As can be seen from the above, the wire multi-station injection molding equipment of the utility model has the following beneficial effects:

[0065] 1. By setting a rotary reversing device, the direction of the wire in the pay-off frame 4 can be automatically changed to reverse, so that a set of injection molds can be used to realize the injection molding of injection molded structural parts in opposite directions on the wire, saving mold costs. During the injection molding process, there is no need to re-clamp the wire, saving employees' clamping time, thereby improving work efficiency.

[0066] 2. The load mechanism 6 of the rotating reversing device uses the electromagnet 62 to instantly power on and off, and controls the adsorption capacity of the electromagnet 62 to achieve fixed connection and release of the pay-off frame 4, which is easy to operate; and by setting the elastic buffer component 63, the electromagnet 62 is controlled to fit closely with the pay-off frame 4 to avoid damage.
