The fixed plate 12 is fixed to the bottom surface of the upper die base 11, the punch 13 and the plurality of positioning posts 14 are connected to the fixed plate 12 and their lower ends extend downward to the bottom of the fixed plate 12. Specifically, there are two punches 13 for punching the trimming waste 101 of the lock 100. The two punches 13 are respectively located on opposite sides of the fixed plate 12 and are arranged oppositely in the length direction of the upper die 1. The plurality of positioning posts 14 surround the outer side of the punch 13 and are close to the outer side wall of the fixed plate 12 relative to the punch 13. The stripper plate 15 is located below the fixed plate 12 and is connected to the lower ends of the plurality of positioning posts 14 so as to move up and down driven by the plurality of positioning posts 14.
[0022] The stripping plate 15 is provided with a stripping hole 151 which runs through it from top to bottom. The stripping hole 151 is slidably matched with the lower end of the punch 13. Specifically, there are two stripping holes 151, and one stripping hole 151 is clearance-matched with one punch 13. The outer wall of the stripping plate 15 is also provided with a cooling channel 152 for conveying coolant. The cooling channel 152 surrounds the outer side of the stripping hole 151 and is connected to the outside of the other outer wall of the stripping plate 15, wherein the coolant is cooling water. A spring 16 is sleeved on a positioning column 14 and abuts against the stripping plate 15 to drive the stripping plate 15 to reset. When the forging (lock 100) is trimmed, the coolant in the cooling channel 152 cools the stripping plate 15, which can prevent the stripping plate 15 from transferring high heat to the spring 16 and causing the spring 16 to fail due to high temperature, thereby extending the service life, and can simplify the container lock trimming mold structure and further reduce costs.
[0023] Specifically, the cooling channel 152 surrounds the outer side of the two stripping holes 151, and the cooling channel 152 is close to the outer side wall of the stripping plate 15 relative to the stripping holes 151 to help reduce the temperature at the corresponding position of the stripping plate 15 and the spring 16, further improve the cooling effect, and achieve the purpose of protecting the spring 16; in this embodiment, in order to further improve the cooling effect, the cooling channel 152 corresponds to a plurality of positioning columns 14, that is, the cooling channel 152 corresponds to a plurality of springs 16. The cooling channel 152 is formed with an input port 1521 and an output port 1522 located on one side of the input port 1521 on the outer side wall of the stripping plate 15. Specifically, the input port 1521 and the output port 1522 are located on the same outer side wall of the stripping plate 15 to facilitate external water pipe connection, wherein the input port 1521 is used to connect the water inlet pipe, and the output port 1522 is used to connect the water outlet pipe. The two adjacent outer walls of the stripping plate 15 are also provided with an opening 17 inwardly connected to the cooling channel 152. The opening 17 is detachably connected to a sealing plug 18 for closing it. Specifically, the sealing plug 18 is threadedly connected to the opening 17. By providing multiple openings 17 and sealing plugs 18, the cooling channel 152 can be flexibly opened or closed according to actual needs.

Specifically, the plurality of equal-height columns 19 are located outside the stripper hole 151 on opposite sides along the length direction of the upper template 122 and are arranged along the length direction of the upper template 122. By providing a plurality of equal-height columns 19, when the lock head 100 is trimmed, the stripper plate 15 can be prevented from being unable to demould due to tilting, thereby ensuring smooth demoulding of the trimmed waste 101 of the lock head 100.

A spring 16 is clearance-matched with a receiving hole 1211 and a through hole 1221 to improve its motion accuracy, and The top surface of the spring 16 abuts against the top surface of the accommodating hole 1211; the upper ends of multiple positioning columns 14 are slidably connected to the pad 121, specifically, the positioning columns 14 and the sliding holes (unnumbered) of the pad 121 are clearance-matched to enable them to slide up and down; the lower ends of multiple positioning columns 14 extend downward and pass through the upper template 122, the upper end of the punch 13 is fixed to the upper template 122 by bolts, and the lower end of the punch 13 extends downward and passes through the upper template 122 to clearance-match with the stripping hole 151.
[0026] The lower die 2 includes a lower die base 21 and a lower die plate 22 fixed to the top surface of the lower die base 21 by bolts. A concave die 221 corresponding to the convex die 13 is provided downwardly on the top surface of the lower die plate 22. There are multiple concave die 221, one concave die 221 corresponds to one convex die 13. In this embodiment, there are two concave die 221. A blanking hole (not numbered) penetrating downwardly through the lower die plate 22 is formed at the lower end of each concave die 221. A through hole (not numbered) penetrating upwardly through the lower die base 21 is provided on the bottom surface of the lower die base 21 corresponding to each blanking hole. When the upper die 1 and the lower die 2 are closed, the convex die 13 cooperates with the concave die 221 to cut off the trimming waste 101 on the lock head 100. At this time, the trimmed lock head 100 falls from the blanking hole through the hole to the outside of the lower die 2.
[0027] The container lock trimming die of the utility model is provided with a cooling channel for conveying coolant on the outside of the stripping hole of the stripping plate. When the forging (lock) is trimmed, the coolant in the cooling channel cools the stripping plate, which can prevent the stripping plate from transferring high heat to the spring and causing the spring to fail due to high temperature, thereby extending the service life. The container lock trimming die of the utility model has the characteristics of simple structure and low cost.
