[0035] In the embodiment of the present application, the upper mold 3 and the lower mold 4 are arranged correspondingly in the upper and lower parts, and the upper pair of locking mechanisms 7 and the lower pair of locking mechanisms 7 are also arranged symmetrically in the upper and lower parts.

[0036] Preferably, a plurality of arc-shaped through grooves are provided on the upper mold 3 and the lower mold 4, and the arc-shaped through grooves of the upper mold 3 and the arc-shaped through grooves of the lower mold 4 are arranged one by one. The upper end of the upper mold 3 and the lower end of the lower mold 4 are connected with a connecting seat 31, and the lower end of the upper base 2 and the upper end of the lower base 5 are provided with an accommodating cavity, and the connecting seat 31 is positioned in the corresponding accommodating cavity.

[0037] Preferably, lugs 21 are provided on both sides of the upper base 2 and the lower base 5 , and the locking mechanism 7 is installed together with the corresponding lugs 21 .

[0038] like Figure 2 As shown, the locking mechanism 7 includes: a box body 73, a rocker rod 75 and a locking assembly, the box body 73 is installed on the corresponding lug 21 by a set screw 732; the rocker rod 75 is hinged in the box body 73 by a hinge shaft 74; the locking assembly is movably connected to the box body 73, the locking assembly and the rocker rod 75 are abutted against each other, the upper locking assembly can drive the rocker rod 75 to abut against the upper mold 3, and the lower locking assembly can drive the rocker rod 75 to abut against the lower mold 4, thereby realizing the fixed installation of the lower mold 4 and the upper base 2 or the fixed installation of the lower mold 4 and the lower base 5.

[0039] In the embodiment of the present application, the locking assembly includes: a side plate 72, a screw 78 and a wedge block 71. The side plate 72 is fixedly connected to the box body 73; the screw 78 is threadedly connected to the side plate 72 so that the screw 78 can move up and down relative to the side plate 72; the wedge block 71 is movably connected to the screw 78 through a connecting assembly, and the rotation of the screw 78 can drive the connecting assembly to drive the wedge block 71 to move up and down.

[0040] When the wedge block 71 moves up to the uppermost end, it is in the unlocking position, and when the wedge block 71 moves down to the lowermost end, it is in the locking position.

[0041] When in the locked position, the wedge block 71 drives the rocker rod 75 to abut against the upper mold 3 or the lower mold 4 .

[0042] like Figure 3 and Figure 4 As shown, the wedge block 71 abuts against the pressure wheel 751 on the swing rod 75, and the wedge block 71 is slidably matched with the boss 731 of the box body 73, so that the wedge block 71 moves smoothly.

[0043] Preferably, the wedge block 71 has an inclined surface 711 , and the pressure wheel 751 is pressed against the inclined surface 711 , and the two are in line contact, which can reduce the mutual friction and make the swing rod 75 swing smoothly.

[0044] Preferably, a plurality of tension springs 782 are connected between the wedge block 71 and the side plate 72, and an elastic element is connected between the rocker arm 75 and the box body 73. When the supporting portion is against the upper mold 3 / lower mold 4, the tension spring 782 is in a stretched state and the elastic element is in a compressed state, and both store energy. When the locking assembly moves up and resets, the elastic element and the tension spring 782 release energy, thereby accelerating the reset of the rocker arm 75.

[0045] The elastic element is a compression spring 76. When the rocker arm 75 is reset, the compression spring 76 applies a biasing force to the rocker arm 75 to prompt the rocker arm 75 to quickly return to the initial position in the unlocked state.

[0046] like Figure 3As shown, the connecting assembly includes: a shell 784, a connecting rod 783, a pressure head 785 and a mounting screw 7841, the shell 784 is fixedly connected to the wedge block 71; the connecting rod 783 is connected to the screw rod 78, and the connecting rod 783 is movably arranged in the shell 784; the pressure head 785 is connected to the connecting rod 783, and the pressure head 785 is pressed in the shell 784; the mounting screw 7841 is horizontally installed on the shell 784, and the end of the mounting screw 7841 can extend into the connecting rod 783 to vertically limit the connecting rod 783.

[0047] like Figure 5 As shown, the connecting rod 783 has a recessed portion, and the mounting screw 7841 is inserted into the shell 784 and abuts against the recessed portion, so that the connecting rod 783 can only rotate freely but cannot move up and down. Under this premise, when the screw rod 78 moves spirally, the connecting rod 783 and the pressure head 785 can rotate in the shell 784 while driving the shell 784 to move upward or downward, so that the operating screw rod 78 can move the wedge block 71 up and down.

[0048] Preferably, a pressure block 77 is also provided on the rocker arm 75, and the pressure block 77 and the pressure wheel 751 are respectively located at the two ends of the rocker arm 75, and the end of the pressure block 77 is connected with a supporting portion, and the supporting portion is an arc-shaped head 771. The arc-shaped head 771 located at the upper side can be pressed against the lower surface of the upper mold 3 to achieve a firm locking of the upper mold 3, and the arc-shaped head 771 located at the lower side can be pressed against the upper surface of the lower mold 4 to achieve a firm locking of the lower mold 4.

[0049] In the embodiment of the present application, a hand wheel 781 is connected to one end of the screw rod 78 away from the connecting assembly to facilitate the operation of the screw rod 78 .

[0050] Working principle: The locking mechanism 7 is pre-installed on the upper base 2, and the connecting seat 31 is aligned with the accommodating cavity of the upper base 2, so that the upper mold 3 is upwardly installed on the upper base 2, and then the hand wheel 781 is turned to make the screw rod 78 rotate clockwise, so that the pressing head 785 presses against the shell 784, and when the screw rod 78 moves downward in a spiral, it drives the wedge block 71 to move downward, and the downward movement of the wedge block 71 will push the swing rod 75 to swing and the tension spring 782 to be stretched, and the swing of the swing rod 75 will cause the compression spring 76 to be compressed, and at the same time, the pressing block 785 is pressed against the shell 784. 7 drives the arc head 771 to approach the upper mold 3, and finally abuts against the lower surface of the upper mold 3. Through the arc movement of the pressing block 77, the upper mold 3 can be pressed tightly against the upper base 2, thereby realizing the installation between the upper mold 3 and the upper base 2. When disassembling, the screw rod 78 is rotated in the opposite direction, the wedge block 71 moves up, and under the resetting action of the compression spring 76 and the tension spring 782, the rocker rod 75 drives the pressing block 77 and the arc head 771 to rotate counterclockwise and reset, thereby realizing disassembly; the installation and disassembly methods of the lower mold 4 and the lower base 5 are the same as above.

[0051] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations.
