[0023] Example 1

[0024] like Figures 1-3 As shown, a maintenance and mold-changing structure for a wire-embedding mold includes a mold-changing trolley 1 and a turntable. The turntable is equipped with a wire-embedding mold, and a lifting mechanism 2 is provided below the turntable. The lifting mechanism 2 is used to lift the wire-embedding mold, so that the wire-embedding mold is separated from the turntable. The lifting mechanism 2 includes a lifting plate 21 coaxially arranged with the wire-embedding mold, and the lifting plate 21 is equipped with multiple ball bearings. The mold-changing trolley 1 is located at the mold-changing station of the turntable and includes a trolley body 11. A transfer push plate 3 is provided above the trolley body 11. The bottom of the transfer push plate 3 is equipped with rollers and is movably connected to the trolley body 11. A positioning component for positioning the wire-embedding tool is provided on its top. When a mold needs to be changed, the turntable rotates to the mold changing station, the mold changing trolley 1 docks with the turntable, the lifting mechanism 2 is activated, the wire inserting mold rises and disengages from the turntable, and then the intermediate push plate 3 on the mold changing trolley 1 is pushed onto the turntable and inserted above the lifting plate 21. Then the lifting mechanism 2 is reset, the intermediate push plate 3 carries the middle of the wire inserting mold, and the handle of the intermediate push plate 3 is pulled to pull the intermediate push plate 3 and the wire inserting mold to be repaired back onto the mold changing trolley 1, thus completing the disassembly and replacement of the wire inserting mold.

[0025] like Figure 1 , 2As shown, the top of the transfer push disc 3 is provided with a handle, the positioning member includes a quick clamp 31, the top of the transfer push disc 3 is provided with a U-shaped positioning hole 32, and the positioning hole 32 is provided with the quick clamp 31 on both sides. When the transfer push disc 3 is inserted above the jacking disc 21, the U-shaped positioning hole 32 is sleeved into the outside of the embedded wire mold, then the jacking mechanism 2 is lowered, the transfer push disc 3 bears the middle part of the embedded wire mold and is completely separated from the rotating disc, and then the quick clamp 31 is started to automatically clamp the embedded wire mold.

[0026] As shown in Figure 1 , the jacking mechanism 2 further includes a first jacking device 22, the first jacking device 22 is arranged at the top of the support 23, the output end of the first jacking device 22 is connected with the bottom of the jacking disc 21, and two symmetrical guide rods 24 are further arranged at the two sides of the first jacking device 22, the top of the guide rod 24 is connected with the jacking disc 21, and the lower end of the guide rod 24 is slidably connected with the support 23.

[0027] As shown in Figure 1 , the jacking disc 21 is a circular disc body, a plurality of balls are uniformly arranged along a plurality of concentric circles on the bottom surface of the disc body, and the balls are alternately arranged on adjacent concentric circles, so that the friction is small during jacking, and the embedded wire mold is uniformly stressed.

The two side plates of the opening end of the opening groove are equipped with guide slopes, and the opening end of the opening groove is also equipped with a stop plate 54 to block the opening. The stop plate 54 is detachably connected to the mobile trolley. With the setting of the mobile trolley 5, the replacement inlay mold can be transported to the maintenance area, and the mold-changing trolley does not need to move, reducing the number of positioning times during mold changing, providing good flexibility, and making operation more convenient.

[0033] The working principle of this utility model is as follows: When a mold needs to be changed, the turntable rotates to the mold changing station, the mold changing trolley 1 connects with the turntable, the lifting mechanism 2 and the lifting mechanism 4 start synchronously, the wire embedding mold rises and disengages from the turntable, the lifting platform 42 is flush with the turntable, the intermediate push plate 3 rises, and then the intermediate push plate 3 on the lifting platform 42 is pushed and inserted above the lifting plate 21. Then the lifting mechanism 2 is reset, the intermediate push plate 3 carries the middle part of the wire embedding mold, and the handle of the intermediate push plate 3 is pulled to pull the intermediate push plate 3 and the wire embedding mold to be repaired back to the mold changing trolley 1, disengaging it from the wire embedding equipment; finally, the limiting plate 45 and the stop plate 54 are disassembled in sequence, the intermediate push plate 3 on the mold changing trolley 1 is pushed into the moving trolley 5, the stop plate is installed, and the moving trolley 5 is pulled out and moved to the repair area; when a new wire embedding mold needs to be installed, the process is reversed. In summary, this utility model has a simple structure, and the use of a mold-changing trolley and a mobile trolley greatly reduces the difficulty of maintenance and mold changing, while also ensuring high operational safety.
