[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 9 In this embodiment, a one-time molding die dedicated to the side plate of a safe is provided, comprising an upper die 1 and a lower die 2, wherein the upper die 1 comprises a top plate 11, an upper molding template 12 is fixedly connected below the top plate 11, and a punching groove 14 is provided on one side of the upper molding template 12;

[0036] The lower mold 2 includes a base 21, a lower molding template 22 is fixedly connected to the top of the base 21, a punching hole 221 is opened on one side of the lower molding template 22, the punching hole 221 can be connected to the punching groove 14, a moving rod 223 for punching is slidably connected to the bottom of the lower molding template 22, a punching column 2231 is fixedly connected to one end of the moving rod 223, and a slope 2232 is provided on the other end of the moving rod 223, and the slope 2232 is located on the lower side of the frame of the upper molding template 12.

[0037] When in use, the embryonic plate is placed on the lower die 2, and the upper die 1 and the lower die 2 are combined for stamping. The shape of the safe side plate is formed between the upper forming template 12 and the lower forming template 22, so that the embryonic plate is formed. When the embryonic plate is formed, the punching groove 14 is connected with the punching eye 221. At the same time, the upper forming template 12 continues to descend through the stamping equipment after the safe side plate is formed. After the frame of the upper forming template 12 descends, the inclined surface 2232 of the moving rod 223 is pressed to make one end of the moving rod 223 move to one side, and the punching column 2231 at the other end of the moving rod 223 is moved out of the punching eye 221, and the rotating shaft hole is punched out on the formed embryonic plate through the punching column 2231.

[0038] In further embodiments, see Figures 2 to 5 The top plate 11 and the upper molding template 12 are fixedly connected with a plurality of guide sleeves 13 on their circumferences, and the base 21 is fixedly connected with a plurality of guide pillars 23 on its circumferences.

[0039] The guide sleeve 13 is lowered and sleeved on the outer side of the guide pillar 23 , thereby limiting the stamping process of the upper die 1 and the lower die 2 , so that the upper die 1 and the lower die 2 are accurately positioned.

[0040] In further embodiments, see Figure 4 A pressing plate 15 is slidably connected inside the upper forming template 12 , and the pressing plate 15 is elastically connected to the upper forming template 12 .

[0041] A connecting column is provided at the upper end of the pressing plate 15, and a connecting sleeve is provided between the top plate 11 and the upper forming template 12. The connecting column passes through the upper forming template 12 and is located inside the connecting sleeve. Springs are provided inside the connecting column and the connecting sleeve, so that the pressing plate 15 and the upper forming template 12 are elastically slidably connected. During stamping, the pressing plate 15 inside the upper forming template 12 presses the embryo plate to further ensure the accuracy during stamping, and the peripheral side of the embryo plate is bent by pressing down the frame of the upper forming template 12.

[0042] In further embodiments, see Figure 6 A mounting block 222 is installed above the base 21 , and two moving rods 223 are slidably inserted below the mounting block 222 , and springs are provided between the moving rods 223 and the mounting block 222 .

[0043] The mounting block 222 allows the moving rod 223 to only slide on the base 21, and a spring is provided between the moving rod 223 and the mounting block 222, so that the moving rod 223 compresses the spring after moving and stamping, so that the moving rod 223 can be pushed to move and reset by the spring reset after the upper forming template 12 is removed, thereby ensuring that subsequent stamping continues.

[0044] In further embodiments, see Figures 6 to 9The lower molding template 22 is internally connected with a lifting plate 225 for sliding up and down, and the lifting plate 225 can extend out of the lower molding template 22. The lower molding template 22 is internally fixedly connected with a fixing rod 227 below the lifting plate 225. The fixing rod 227 is symmetrically slidably connected with a moving block 226. A spring 228 is arranged between the moving blocks 226. A connecting rod 224 is fixedly connected above the moving rod 223. One end of the connecting rod 224 is inserted into the lower molding template 22 and is fixedly connected with a pushing block 2241. The pushing block 2241 is located on one side of the moving block 226 and is connected to the fixing rod 227. Sliding connection, the interior of the lower forming template 22 is fixedly connected with a fixed seat 229 on both sides of the fixed rod 227, a pushing plate 210 is slidably connected above the fixed seat 229, the pushing plate 210 is located below the lifting plate 225, a movable plate 211 is slidably connected below the pushing plate 210, a spring 212 is provided between the movable plate 211 and the pushing plate 210, one end of the moving block 226 is located between the fixed seats 229 and below the movable plate 211, the upper end height of the moving block 226 is higher than the upper end height of the fixed seat 229, and the end of the moving block 226 close to the movable plate 211 is an inclined plane.

[0045] The moving rod 223 drives the connecting rod 224 to move during the movement. When the connecting rod 224 moves, the pushing block 2241 is driven to move on the fixed rod 227. The pushing block 2241 pushes the moving block 226 to move. The two moving blocks 226 move close to each other to the bottom of the movable plate 211. The moving block 226 compresses the spring 228. The movable plate 211 is lifted by the inclined plane at one end of the moving block 226. The formed embryo plate and the upper forming template 12 are arranged above the lifting plate 225 and cannot rise, so the pushing plate 210 cannot rise either. The spring 212 between the movable plate 211 and the pushing plate 210 is compressed. After the spring 212 is compressed, the pushing plate 210 can be pushed upward after the upper forming template 12 is moved away. The pushing plate 210 thereby lifts the lifting plate 225, thereby lifting the embryo plate formed on the lower forming template 22, thereby facilitating its removal from the upper mold 1 and the lower mold 2, and facilitating the addition of subsequent embryo plates.

[0046] In further embodiments, see Figures 8-9 A limiting hole 2261 is provided on one side of the moving block 226, and a plurality of fixed limiting plates 24 are fixedly connected to the lower forming template 22 above the base 21. A movable limiting plate 25 is installed on one side of the lower forming template 22, and a limiting rod 253 is fixedly connected to one side of the movable limiting plate 25. One end of the limiting rod 253 is inserted into the lower forming template 22 and located on one side of the moving block 226, and one end of the limiting rod 253 can be inserted into the limiting hole 2261.

[0047] After the moving block 226 moves, the limiting hole 2261 moves to the side of the limiting rod 253, and one end of the limiting rod 253 is inserted into the limiting hole 2261 under the action of external force, so that the moving block 226 is restricted below the movable plate 211. After the upper forming template 12 is removed, the moving rod 223 is reset, and the connecting rod 224 is reset with the pushing block 2241, the moving block 226 is always located below the movable plate 211, so that the movable plate 211 remains in the raised position, so that the pushing plate 210 is lifted when the spring 212 is restored and extended.

[0048] The embryo plate placed on the lower molding template 22 can be limited by multiple fixed limiting plates 24 and movable limiting plates 25, and the movable limiting plates 25 can be moved. When placing the embryo plate, first insert one side of the embryo plate between the fixed limiting plates 24, push the movable limiting plate 25 away from the lower molding template 22 through one end of the embryo plate, and the other end of the embryo plate directly falls between the multiple limiting plates under the action of gravity. After the movable limiting plate 25 is reset under the action of external force, the embryo plate is automatically clamped and positioned between the multiple limiting plates. This makes it convenient for users to place the embryo plate on the lower molding template 22. After the embryo plate is tilted, the embryo plate will not be unable to fall from the top of the limiting plate to the top of the lower molding template 22 due to its thickness.

[0049] At the same time, when the movable limiting plate 25 moves away from the lower forming template 22, it also pulls the limiting rod 253 to disengage from the limiting hole 2261, so that the moving block 226 can be reset under the elastic force of the spring 1 228. The lifting plate 225, the pushing plate 210 and the movable plate 211 are also reset under the action of gravity after losing the support of the moving block 226, so that the upper end of the lower forming template 22 is flush so that the embryo plate can be placed.

[0050] In further embodiments, see Figure 8 A second fixing rod 252 is fixedly connected to the base 21 , and the second fixing rod 252 passes through the movable limiting plate 25 . A third spring 251 is connected between the movable limiting plate 25 and the lower forming template 22 .

[0051] By fixing the second rod 252, the movable limit plate 25 can only slide away from the lower molding template 22. At the same time, when the movable limit plate 25 moves away from the lower molding template 22, the movable limit plate 25 stretches the spring three 251, thereby ensuring that the movable limit plate 25 can be reset under the action of the spring three 251 when the external force is lost. At the same time, the pulling state of the movable limit plate 25 by the spring three 251 also provides a state that when the limit hole 2261 moves to one side of the limit rod 253, one end of the limit rod 253 can be inserted into the limit hole 2261.

[0052] In a further embodiment, the rising height of the lifting plate 225 is greater than the thickness of the side plate of the safe.

[0053] Ensure that the lifting plate 225 can completely lift the safe side plate and separate it from the lower forming template 22 when it is raised.

[0054] In a further embodiment, the space between the fixed limiting plate 24 , the movable limiting plate 25 and the lower forming template 22 can accommodate the upper forming template 12 .

[0055] It is ensured that the upper forming template 12 can be lowered for stamping, and at the same time, the lowest height of the upper forming template 12 must also be higher than the height of the second fixing rod 252 and the third spring 251.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
