[0040] Specific implementation plan: see Figure 1-Figure 9The utility model is a tooling die base used for round dragon buckle head automatic assembly equipment, comprising:

[0041] The mold base body 1 is provided with a slideway 12 and a through-port 15, wherein the slideway 12 extends in the front-to-back direction, the through-port 15 extends in the up-down direction, and the through-port 15 is located in front of the slideway 12;

[0042] The sliding frame 2 is slidably connected in the slideway 12, and the upper end surface of the sliding frame 2 is provided with a ring 41 placement groove 22 for placing the ring 41, the front end of the ring 41 placement groove 22 is connected to the outside, and a first reset structure is provided between the sliding frame 2 and the mold base body 1;

[0043] The lifting block 3 is slidably connected in the through opening 15, and the upper end surface of the lifting block 3 is provided with a trigger 42 placement groove 31 for placing the trigger 42, a portion of the trigger 42 is located outside the trigger 42 placement groove 31, and is placed above the mold base body 1, and the trigger 42 is provided with a convex column 421 for installing the torsion spring 43, and a second reset structure is provided between the lifting block 3 and the mold base body 1;

[0044] The tooling mold base has a device to be assembled and an assembled state. In the state to be assembled, the upper end of the lifting block 3 extends above the mold base body 1, and the rear end of the sliding frame 2 extends to the rear of the mold base body 1; in the assembled state, the lifting block 3 descends, the sliding frame 2 slides forward, and approaches the lifting block 3.

[0045] For easier understanding, please refer to Figure 2 and Fig. 9 , the structure of the round dragon buckle head 4 is described below (the structure of the round dragon buckle head 4 belongs to the prior art, and only a brief description is given here):

[0046] In this embodiment, the round dragon button 4 includes a ring 41, a trigger 42 and a torsion spring 43, wherein an opening is provided on the ring 41, and a rotating shaft 411 is provided at one end of the ring 41 corresponding to the opening, and a boss 421 and a rotating groove 422 are provided on the trigger 42, wherein the torsion spring 43 is installed on the boss 421, and the rotating groove 422 is used to cooperate with the rotating shaft 411 to transfer the trigger 42 to the ring 41. When the trigger 42 is rotatably installed on the ring 41, the rotation of the trigger 42 can be achieved by moving the trigger 42 and cooperating with the torsion spring 43, and a notch is formed on the ring 41 at the same time, and the trigger 42 is released, and the reset of the trigger 42 can be completed by the torsion of the torsion spring 43, and the notch is closed at this time.

[0047] Next, see Figure 5-Figure 7 It can be seen that in this embodiment, the first reset structure includes:

[0048] A first mounting hole 13 is arranged inside the mold base body 1, and the first mounting hole 13 is located below the slideway 12;

[0049] The connecting block 24 is fixed below the sliding frame 2 and is located in front of the first mounting hole 13. The connecting block 24 is provided with a third mounting hole 241;

[0050] The first spring is installed between the first installation hole 13 and the third installation hole 241 .

[0051] In addition, in this embodiment, a limiting plate 14 is fixed to the rear end of the mold base body 1 , and in the state to be assembled, the connecting block 24 abuts against the front of the limiting plate 14 .

[0052] Working principle of the first reset structure: When the round dragon buckle head 4 needs to be assembled, the sliding frame 2 needs to be pushed forward and the sliding frame 2 and the lifting block 3 need to be brought close to each other. Therefore, a first driving mechanism is provided at the rear of the tooling mold base (the first driving mechanism can adopt the structure of a cylinder and a push block. This is a conventional technical means and will not be elaborated on here). When the first driving mechanism pushes the sliding frame 2 forward, the sliding frame 2 slides along the slideway 12. Since the first spring is installed between the first mounting hole 13 and the third mounting hole 241, the first spring is compressed at this time. After the round dragon buckle head 4 is assembled, the first driving mechanism cancels the drive to the sliding frame 2. At this time, the first spring recovers its deformation and drives the sliding frame 2 to translate backward and reset.

[0053] Note that since the limiting plate 14 is fixed to the rear end of the mold base body 1 , the sliding frame 2 will not be separated from the slideway 12 .

[0054] Then, see Figure 4 and Figure 8 In this embodiment, the second reset structure includes:

[0055] A fixing block 16 is fixed to the front end of the mold base body 1, and at least a portion of the fixing block 16 is located in the through opening 15;

[0056] The second spring is installed between the fixed block 16 and the lifting block 3.

[0057] Moreover, in the present embodiment, a clearance groove 32 is provided on the lifting block 3 for the fixing block 16 to pass through, and a second mounting hole 161 is provided on the fixing block 16 for placing one end of the second spring. In the state to be assembled, a space is left between the upper groove wall of the clearance groove 32 and the fixing block 16, and the second spring is arranged vertically in the space.

[0058] The working principle of the second reset structure: in the state to be assembled, the upper end of the lifting block 3 extends to the top of the mold base body 1, and then cooperates with the upper end surface of the mold base body 1 to form a trigger 42 placement groove 31 for the trigger 42 to be placed. When the round dragon buckle head 4 needs to be assembled, it is necessary to push the lifting block 3 downward and make the trigger 42 located above the lifting block 3 (since part of the trigger 42 is placed above the mold base body 1, when the lifting block 3 descends, the trigger 42 remains in place). In this embodiment, a first driving mechanism is provided above the tooling mold base (the second driving mechanism can adopt the structure of a cylinder and a push block, which is a conventional technical means and will not be described in detail here). When the second driving mechanism drives the lifting block 3 downward, since the second spring is installed between the fixed block 16 and the lifting block 3, the second spring is compressed at this time. After the round dragon buckle head 4 is assembled, the second driving mechanism cancels the drive to the lifting block 3, at which time the second spring recovers its deformation and drives the lifting block 3 to translate upward and reset.

[0059] See also Figure 1 and Figure 6 It can be seen that in this embodiment, a connecting ring 44 is fixed on the circular ring 41, and a connecting ring 44 placement groove 23 is provided on the sliding frame 2 for the connecting ring 44 to be matched and placed, and the connecting ring 44 placement groove 23 is connected to the circular ring 41 placement groove 22. Here, the connecting ring 44 on the circular ring 41 is used to match the round dragon buckle head 4 to connect the key ring.

[0060] See also Figure 5 It can be seen that in this embodiment, slide rails 11 are respectively provided on the left and right sides of the upper end of the mold base body 1, and a slideway 12 is formed between the two slide rails 11.

[0061] More specifically, a first positioning groove 221 and a second positioning groove 222 for cooperating and positioning the circular ring 41 are provided at the bottom of the groove 22 for placing the circular ring 41 .

[0062] Here, the part of the ring 41 corresponding to the rotating shaft 411 is set as the end of the ring 41, and the end is placed on the first positioning groove 221, and the second positioning groove 222 corresponds to the main part of the ring 41, so as to better realize the positioning and placement of the ring 41, and ensure that when the ring 41 is placed in the ring 41 placement groove 22, the opening position of the ring 41 is opposite to the trigger 42, and when the trigger 42 is pushed backward, the trigger 42 can be installed into the opening of the ring 41.

[0063] The following is a brief description of the assembly process of the round dragon buckle head 4:

[0064] In the state to be assembled, the ring 41 is placed in the ring 41 placement groove 22, the trigger 42 is placed in the trigger 42 placement groove 31, and the torsion spring 43 is installed on the protrusion 421 of the trigger 42. When entering the assembly process, first, the first driving mechanism drives the sliding frame 2 to move forward along the slide 12 and approach the lifting block 3; then, the second driving mechanism drives the lifting block 3 to descend, so that the trigger 42 is placed above the lifting block 3; then, the third driving mechanism (the third driving mechanism can adopt the structure of a cylinder and a push block, which is a conventional technical means and will not be described in detail here) drives the trigger 42 to move backward and install the trigger 42 on the ring 41 (the rotating shaft 411 of the ring 41 is placed in the rotating groove 422 of the trigger 42), and the assembly of the round dragon buckle head 4 can be completed. After the round dragon buckle head 4 is assembled, the first driving mechanism translates backward, the sliding frame 2 is driven to reset backward via the first reset structure, the third driving mechanism resets forward, the second driving mechanism translates upward, and the lifting block 3 is driven to reset upward via the second reset structure.
