Multiple upper cover plates 1 can be provided, so as to ensure that the mold connection is more stable. The upper die base 2 can be used to connect and install the shell punching module 7, the lock core head forming module 8 and the shell forming module 9. Multiple lower pads 4 can be used to support the lower die base 3. The setting of the lower die base 3 can be used to support and install the shell punching module 7, the lock core head forming module 8 and the shell forming module 9. The setting of the outer guide sleeve 5 and the outer guide column 6 can ensure that when the upper and lower molds are closed, the mold closing is accurate and there is no deviation, so that the material strip punched into the mold has higher precision and the product yield is higher. The shell punching module 7 can punch and shell the material strip so that the material strip forms a basic lock core shell shape. The lock core head forming module 8 can expand and form the head of the shell punched in the previous process to complete the process of expanding the lock core head. The shell forming module 9 can further punch the lock core shell after the head is expanded, complete the functions of shaping, side punching and grooving, and complete the lock core shell forming process.

The lower end of the lock core head punch 84 passes through the first upper clamping plate 81, the first stop plate 82 and the first upper stripping plate 83 in sequence and extends out of the bottom of the first lower stripping plate 88, and the first lower pad 89 is fixedly installed on the top of the lower die seat 3. The first lower stripping plate 88 is mounted on the upper part of the first lower pad 89 so as to be movable up and down, the two slider seats 85 are mounted on the top of the first lower stripping plate 88 in a front-to-back arrangement, and the two lower sliders 86 are mounted on two corresponding slider seats 85. The bottoms of the two lower inserting knives 87 are mounted on the top of the first lower pad 89 in a front-to-back arrangement, respectively. When the first lower stripping plate 88 moves down and up, the two lower inserting knives 87 can drive the two corresponding lower sliders 86 to move inward and contact and move outward and separate, respectively. The inner sides of the two lower sliders 86 are both provided with a semi-cylindrical forming groove 10, and the upper inner wall of the forming groove 10 is provided with a semi-circular ring groove.

[0022] Reference Figures 1 to 3 and Figure 6 The first upper clamping plate 81 can be connected to the upper die seat 2 to play a role of connection and fixing. The first stopper plate 82 can stop the first upper stripping plate 83 with paper and has a stopper function. The first upper stripping plate 83 can separate the lock core head punch 84 from the material strip when the mold is separated. The lock core head punch 84 can form and expand the top of the lock core housing in the previous process. The two slider seats 85 can be used to install the two corresponding lower sliders 86 in front and behind, so that the lower sliders 86 can move inward or outward. The two lower sliders 86 can approach inward, and at the same time, the middle molding groove 10 forms a cylindrical inner groove after the inner part approaches. At the same time, the annular grooves of the two lower sliders 86 contact to form a semicircular groove of an annular ring, so that the top of the lock core housing can expand into the annular groove after the mold is closed, forming the expanded part of the lock core head. The two lower inserts 87 can drive the two lower sliders 86 to move inward and outward, and have a driving and matching function. The first lower stripping plate 88 can lift the material strip and has a stripping function. The first lower pad 89 has a connecting and fixing function.
