[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0027] like Figures 1 to 7 As shown, a quick-locking mechanism is disclosed, which includes an upper template 1 and a lower template 2, as well as a positioning pin 3 and an elastic self-resetting locking component 4. The positioning pin 3 is disposed on the upper template 1 and has a slot 321. The lower template 2 has a positioning hole 21 that matches the positioning pin 3. The elastic self-resetting locking component 4 is disposed in the lower template 2 and one end of the elastic self-resetting locking component 4 extends into the positioning hole 21. When the positioning pin 3 is inserted into the positioning hole 21, the elastic self-resetting locking component 4 is engaged in the slot 321 to achieve quick locking between the upper template 1 and the lower template 2.

[0028] This quick-locking mechanism utilizes the positioning pin 3 and positioning hole 21 to achieve rapid positioning of the upper template 1 and lower template 2, and utilizes the elastic self-resetting locking component 4 and the slot 321 on the positioning pin 3 to achieve rapid locking of the upper template 1 and lower template 2. Since the locking method is more convenient, tighter, and more stable, this quick-locking mechanism can not only achieve rapid locking of the upper template 1 and lower template 2 while ensuring the locking force, but also has a simple structure and is easy to operate. It solves the problems of troublesome, time-consuming, and labor-intensive installation of the upper template 1 and lower template 2, which affects production efficiency, and improves production efficiency.

[0029] In some embodiments, the elastic self-resetting locking assembly 4 includes a locking block 41, an elastic element 42, and a screw plug 43. The lower template 2 has a mounting hole that communicates with the positioning hole 21, and the axis of the mounting hole is perpendicular to the axis of the positioning hole 21. The locking block 41, the elastic element 42, and the screw plug 43 are sequentially installed in the mounting hole. The locking block 41 has a locking protrusion 411 located within the positioning hole 21 and used to engage with the locking groove 321. This configuration enables the locking block 41 to self-reset, facilitating smooth engagement of the locking protrusion 411 with the locking groove 321.

[0030] Specifically, the locking block 41 is slidably installed in the mounting hole, the screw plug 43 is threadedly connected to the opening of the mounting hole, and the elastic element 42 is located between the locking block 41 and the screw plug 43. To ensure the working stability of the elastic element 42, the designer has provided a mounting post 412 on the locking block 41. One end of the elastic element 42 is sleeved on the mounting post 412, and the other end of the elastic element 42 abuts against the screw plug 43. Since springs have good elastic self-resetting ability, in some embodiments the elastic element 42 is preferably a spring. Of course, an elastic rubber body can also be used, depending on the actual needs, which will not be elaborated here.

[0031] In some embodiments, the latching protrusion 411 is provided with a first pushing slope 413 for engaging with the positioning pin 3. This arrangement ensures that the positioning pin 3 can smoothly push the locking block 41, so that the positioning pin 3 can be smoothly inserted into the positioning hole 21.

[0032] In some embodiments, the positioning pin 3 includes a stepped pin head 31 and a pin rod 32. The upper template 1 is provided with a stepped hole adapted to the positioning pin 3. The pin head end of the positioning pin 3 is fixed inside the upper template 1. The end of the pin rod 32 away from the pin head 31 is tapered and the pin rod 32 extends out of the stepped hole to engage with the positioning hole 21. A slot 321 is provided on the pin rod 32. This configuration achieves the fixation of the positioning pin 3 to the upper template 1.

[0033] In some embodiments, the locating pin 3 is fixed inside the upper template 1 by a set screw 5, and the pin 32 is provided with a tightening surface 322 that cooperates with the set screw 5. Of course, the locating pin 3 can also be directly fastened to the upper template 1 with screws, depending on the actual needs, which will not be elaborated here.

[0034] In some embodiments, the quick-locking mechanism further includes an anti-rotation structure to prevent the positioning pin 3 from rotating within the stepped hole. By providing the anti-rotation structure, the slot 321 and the protrusion 411 are smoothly engaged, further improving the stability of the quick-locking mechanism during use.

[0035] In some embodiments, one side of the pin head 31 is cut, and the stepped hole includes a large hole section adapted to the pin head 31 and a small hole section adapted to the pin shank 32. The pin head 31 and the large hole section constitute an anti-rotation structure. The large hole section is adapted to the cut pin head 31, and the anti-rotation of the positioning pin 3 is achieved through the cooperation between the pin head 31 and the large hole section. This design is not only an efficient mechanical anti-rotation solution, but also greatly reduces production costs.

[0036] In some embodiments, the quick-locking mechanism is further equipped with a quick-unlocking device 6, which is used to quickly unlock the upper template 1 and the lower template 2. By providing the quick-unlocking device 6, it is easy to disassemble the upper template 1 and the lower template 2 in a timely and rapid manner, which not only makes disassembly simple and labor-saving, but also further improves production efficiency.

[0037] In some embodiments, the quick-unlocking device 6 includes an unlocking pin 61, an unlocking hole 22 on the lower template 2, the unlocking hole 22 communicating with the mounting hole and the axis of the unlocking hole 22 being perpendicular to the axis of the mounting hole, and a second pushing inclined surface 414 on the locking block 41 cooperating with the unlocking pin 61. The second pushing inclined surface 414 is located inside the unlocking hole 22. When the unlocking pin 61 is inserted into the unlocking hole 22, the unlocking pin 61 pushes the second pushing inclined surface 414 to disengage the locking protrusion 411 from the locking groove 321. Only one unlocking pin 61 is needed to unlock the upper template 1 and the lower template 2, which greatly reduces production costs.

[0038] In some embodiments, the quick-unlocking device 6 further includes a support base 62, on which the unlocking pin 61 is fixedly disposed. By setting the support base 62, the unlocking pin 61 is fixed, which facilitates quick unlocking of the upper template 1 and the lower template 2.

[0039] In some embodiments, the upper template 1 is provided with four positioning pins 3, which are arranged at the four corners of the upper template 1. Correspondingly, the lower template 2 is provided with four elastic self-resetting locking components 4, and the quick unlocking device 6 has four unlocking pins 61, which are arranged at the four corners of the lower template 2 and at the four corners of the support base 62. The specific number of positioning pins 3, elastic self-resetting locking components 4, and unlocking pins 61 can be set according to actual needs, and will not be elaborated here.

[0040] When the upper template 1 and the lower template 2 are locked, the positioning pin 3 is inserted into the positioning hole 21. The positioning pin 3 contacts the first pushing inclined surface 413, and the positioning pin 3 pushes the locking block 41 so that the locking block 41 compresses the elastic element 42 and moves in the direction of the elastic element 42. When the slot 321 corresponds to the protrusion 411, the locking block 41 moves in the direction of the positioning pin 3 under the elastic force of the elastic element 42 until the protrusion 411 falls into the slot 321, thereby realizing the rapid locking of the upper template 1 and the lower template 2.

[0041] When the upper template 1 and the lower template 2 are unlocked, the unlocking pin 61 is inserted into the unlocking hole 22. The unlocking pin 61 contacts the second pushing inclined surface 414, and the unlocking pin 61 pushes the locking block 41 so that the locking block 41 compresses the elastic element 42 and moves it in the direction of the elastic element 42. When the card protrusion 411 disengages from the card slot 321, the upper template 1 and the lower template 2 are quickly unlocked.

[0042] The above describes in detail some embodiments of the quick mold-locking mechanism of this utility model. The embodiments are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. Of course, there are more embodiments, which will not be elaborated here.

[0043] In summary, the quick-locking mechanism of this utility model can not only achieve quick locking of the upper template 1 and the lower template 2 while ensuring the locking force, but also has a simple structure and is easy to operate. It solves the problems of troublesome, time-consuming and labor-intensive installation of the upper template 1 and the lower template 2, which affects production efficiency and improves production efficiency.

[0044] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
