An upper mold assembly is installed on the lifting end of the press body 1, and a lower mold assembly adapted to the upper mold assembly is installed at the bottom of the press body 1. The press body 1 includes a lifting plate and a base. Multiple guide rods are connected between the lifting plate and the base. A connecting hole for connecting hydraulic rods is provided on the top of the lifting plate. The lifting plate can be connected to existing ordinary punch presses, pneumatic punch presses, electric pressing machines, and hydraulic presses to achieve mold closing with the lower mold assembly. The upper mold assembly includes an upper mold fixing plate 2 fixed to the bottom of the lifting plate. An upper mold pressing head 3 is fixed to the bottom of the upper mold fixing plate 2. A pressing groove adapted to the metal part 13 is opened at the bottom of the upper mold pressing head 3. The upper mold pressing head 3 can move downward under the drive of the press body 1. The pressing groove can cooperate with the lower mold base 6 to squeeze the edge of the metal part 13. The circumference of the metal part 13 begins to gradually tilt and wrap around the edge of the plastic part 12, so that the metal part 13 and the plastic part 12 fit tightly.

[0029] There are two upper mold components and two lower mold components, and the lower mold bases 6 in the two lower mold components are symmetrically arranged. The two sets of symmetrical lower mold bases 6 can achieve the purpose of synchronous fastening and installation of two sets of symmetrical metal parts 13 and plastic parts 12.

[0030] The lower mold assembly includes a lower mold fixing plate 5 and a lower mold plate 4 mounted on the lower mold fixing plate 5. A mold closing opening is located at the center of the lower mold plate 4, and a guide slope 11 is provided at the top edge of the mold closing opening. A lower mold base 6 is located inside the mold closing opening. Multiple guide posts 15 are fixed on the lower mold fixing plate 5. A guide slot 14 is provided at the bottom of the lower mold base 6 to slide and engage with the guide posts 15. The guide posts 15 and the guide slot 14 enable the lower mold base 6 to slide and guide the movement of the mold. Plastic parts 12 and metal parts 13 are stacked and assembled on the lower mold base 6. A spring 10 is located at the bottom of the lower mold base 6. A slot for placing the spring 10 is provided on the lower mold fixing plate 5. A top block 7 corresponding to the locking feet on the metal parts 13 is fixed on the lower mold fixing plate 5. A side sliding hole 8 is provided on the lower mold base 6 and fitted onto the top block 7. A sloped port 9 is provided at the outer edge of the top of the side sliding hole 8. When the upper mold assembly is opened, the lower mold base 6... Under the elastic force of spring 10, the product is in an upward floating state. The pre-assembled product of plastic part 12 and metal part 13 is placed on the lower mold base 6. At this time, the retaining foot on metal part 13 is in a vertical downward state and the bottom end of the retaining foot is in contact with the guide slope 11 at the top of the mold closing port. When the mold is closed, the circumference of metal part 13 begins to gradually tilt and wrap around the edge of plastic part 12. When the upper mold assembly moves downward, it squeezes metal part 13, causing the bottom end of the retaining foot to flip inward along the guide slope 11. The retaining foot of metal part 13 is in an inclined state and flips into the side sliding hole 8 under the guidance of the slope port 9. The upper mold assembly continues to move downward and after pressing against metal part 13, spring 10 is in a compressed state.

When the upper mold assembly is opened, the lower mold base 6 is in an upward floating state under the elastic force of the spring 10. The pre-assembled product of plastic part 12 and metal part 13 is installed on the lower mold base 6. At this time, the clamping foot on the metal part 13 is in a vertical downward state and the bottom end of the clamping foot abuts against the guide slope 11 at the top of the mold closing port. When the mold is closed, the upper mold pressure head 3 can move downward under the drive of the press body 1. The pressure groove can cooperate with the lower mold base 6 to squeeze the edge of the metal part 13, and the circumference of the metal part 13 begins to gradually tilt. The metal part 13 is obliquely wrapped around the edge of the plastic part 12, making the metal part 13 fit tightly against the plastic part 12. When the upper mold pressure head 3 moves downward, it squeezes the metal part 13, causing the bottom end of the clamping foot to flip inward along the guide slope 11. The clamping foot of the metal part 13 is in an inclined state and flips into the side sliding hole 8 under the guidance of the slope port 9. The upper mold assembly continues to move downward, and after pressing against the metal part 13, the spring 10 is in a compressed state. At this time, the top block 7 relative to the lower mold base 6 begins to move upward along the side sliding hole 8, pressing the bottom end of the clamping foot of the metal part 13 upward until it is fastened to the inside of the plastic part 12, thus completing the purpose of the metal part 13 covering the plastic part 12 around the inverted perimeter and the automatic and rapid bending of the clamping foot.
