[0027] like Figures 1 to 5As shown, a lower clamping assembly of the utility model includes a lower mold base 1, a lower clamping body 2, a first lower clamping jaw 3, a second lower clamping jaw 4 and a lower clamping spring 5; the lower clamping body 2 is arranged on the lower mold base 1; the lower end of the first lower clamping jaw 3 is rotatably arranged on the lower clamping body 2, and a first auxiliary positioning groove 31 is formed on the inner side of the upper end of the first lower clamping jaw 3; the lower end of the second lower clamping jaw 4 is rotatably arranged on the lower clamping body 2, and a second auxiliary positioning groove 41 is formed on the inner side of the upper end of the second lower clamping jaw 4, and the second auxiliary positioning groove 41 is arranged opposite to the first auxiliary positioning groove 31; one end of the lower clamping spring 5 is connected to the first lower clamping jaw 3, and the other end of the lower clamping spring 5 is connected to the second lower clamping jaw 4, so that the first auxiliary positioning groove 31 and the second auxiliary positioning groove 41 have a tendency to approach each other.
[0028] Thus, the lower clamp assembly of the utility model, when in use, places the buckle surface in the lower clamp body 2, so that one side of the buckle surface is limited by the first auxiliary positioning groove 31, and the other side of the buckle surface is limited by the second auxiliary positioning groove 41, thereby effectively positioning the buckle surface, so that the buckle surface is not easily displaced when connected with the fabric and the buckle body. By providing the lower clamp spring 5, the first auxiliary positioning groove 31 and the second auxiliary positioning groove 41 have a tendency to approach each other, so that the first auxiliary positioning groove 31 can fit one side of the buckle surface, and the second auxiliary positioning groove 41 can fit the other side of the buckle surface, thereby improving the positioning effect of the buckle surface.
[0029] Optionally, a first limiting groove 11 is formed on one side of the lower die base 1, and a second limiting groove 12 is formed on the other side of the lower die base 1; a first limiting plate 21 is provided on one side of the lower clamping body 2, and the first limiting plate 21 is located in the first limiting groove 11; a second limiting plate 22 is provided on the other side of the lower clamping body 2, and the second limiting plate 22 is located in the second limiting groove 12. When the lower clamping body 2 is connected to the lower die base 1, the first limiting plate 21 is placed in the first limiting groove 11, so that the first limiting groove 11 limits the first limiting plate 21, and the second limiting plate 22 is placed in the second limiting groove 12, so that the second limiting groove 12 limits the second limiting plate 22, thereby completing the docking of the lower die base 1 and the lower clamping body 2, so that the lower clamping body 2 is locked on the lower die base 1.
[0030] Furthermore, one side of the bottom of the first limiting plate 21 extends outward to form a first connecting block 23, a first through hole is provided on the first connecting block 23, and the other side of the bottom of the first limiting plate 21 extends outward to form a second connecting block 24, a second through hole is provided on the second connecting block 24; a first connecting channel is provided on the first lower clamping jaw 3, and the first connecting channel, the second through hole and the first through hole are located on the same straight line. When the first lower clamping jaw 3 is connected to the lower clamping body 2, a connecting pin is used to pass through the first through hole, the first connecting channel and the second through hole in sequence, so that the first lower clamping jaw 3 can be rotatably arranged on one side of the lower clamping body 2.
[0031] Furthermore, one side of the bottom of the second limiting plate 22 extends outward to form a third connection block 25, and a third through hole is set on the third connection block 25.

[0032] In order to prevent the fabric from wrinkling when the buckle surface is connected to the fabric and the buckle body, a tightening plane 29 is formed on the top of the lower clamp body 2 of this embodiment to press the fabric when the buckle is made and reduce the wrinkling of the fabric. A mold rod channel for the lower mold rod 10 to pass through is provided in the lower mold base 1. The end of the lower mold rod 10 passes through the mold rod channel and is located in the lower clamp body 2. When the buckle surface is connected to the buckle body and the fabric, the lower mold base 1 and the lower clamp body 2 move along the lower mold rod 10, and the lower mold rod 10 presses the buckle surface, thereby realizing the connection between the buckle surface, the buckle body and the fabric.

[0034] Furthermore, the first lower clamping jaw 3 has a first abutting surface 33 formed inside thereof to abut against the first limiting plate 21, and the second lower clamping jaw 4 has a second abutting surface 43 formed inside thereof to abut against the second limiting plate 22. Under the action of the lower clamping spring 5, the first abutting surface 33 abuts against the first limiting plate 21, and the second abutting surface 43 abuts against the second limiting plate 22.
[0035] In this embodiment, a first clearance opening 27 for inserting the upper end of the first lower clamping jaw 3 is provided on one side of the lower clamping body 2, and a second clearance opening 28 for inserting the upper end of the second lower clamping jaw 4 is provided on the other side of the lower clamping body 2.

[0036] In some examples, a positioning member 6 is further included to connect the lower clamping body 2 with the lower die base 1, and the end of the positioning member 6 passes through the lower clamping body 2 and the lower die base 1. By providing the positioning member 6, after the first limiting plate 21 is placed in the first limiting groove 11, and the second limiting plate 22 is placed in the second limiting groove 12 to complete the docking of the lower die base 1 and the lower clamping body 2, the end of the positioning member 6 passes through the lower clamping body 2 and the lower die base 1, thereby completing the fixing of the lower clamping body 2 on the lower die base 1, and the assembly process is simple and convenient.
[0037] In order to facilitate the insertion of the end of the positioning member 6 into the lower clamping body 2 and the lower mold base 1, a first clearance hole 34 is formed in the middle of the first lower clamping jaw 3 for one end of the positioning member 6 to pass through, and a second clearance hole 44 is formed in the middle of the second lower clamping jaw 4 for the other end of the positioning member 6 to pass through.
[0038] Furthermore, an introduction port is provided on the lower clamp body 2 for introducing the buckle surface into the first limiting groove 11 and the second limiting groove 12. By providing the introduction port, the buckle surface is convenient to move along the first introduction arc surface 32 and the second introduction arc surface 42 through the introduction port, so that the first auxiliary positioning groove 31 fits one side of the buckle surface and the second auxiliary positioning groove 41 fits the other side of the buckle surface, thereby realizing the positioning of the buckle surface.
