[0030] Specific usage method and function of this embodiment:

[0031] In the present utility model, as Figure 1 shown, the component body 1 is in the mold closing state. At this time, the insertion block of the convex mating module 3 is inserted into the insertion groove of the concave mating module 6. At the same time, the dovetail groove of the upper injection mold 2 mates with the dovetail block of the convex mating module 3 and is fixed by the fixed anti-disengagement column 4. The state is as Figure 6 shown. The dovetail groove of the lower injection mold 5 mates with the dovetail block of the concave mating module 6 and is fixed by the fixed anti-disengagement column 4. The state is as Figure 5 shown. Thus, it is convenient for the disassembly and assembly operations of the convex mating module 3 and the concave mating module 6. The flipping locking plate 8 is in a horizontal state, and the mold closing locking column 9 is inside the arc-shaped strip groove of the lower injection mold 5. When as Figure 1As shown, when the component body 1 is locked during mold clamping, the left end of the flipping locking plate 8 is flipped upward by 135 degrees, and the mold clamping locking post 9 is driven by the flipping locking plate 8 to flip into the arc-shaped strip groove of the upper injection mold 2, and the state is as Figure 3 shown. Thus, the mold clamping and locking of the upper injection mold 2 and the lower injection mold 5 are realized. At the same time, the reverse operation is the mold clamping and locking release operation, so that the mold clamping and locking can be quickly switched on and off by the flipping of the flipping locking plate 8.

[0032] Embodiment 2:

[0033] The difference from Embodiment 1 is that the regular hexagon groove of the fixed anti-detachment post 4 can also be set as a regular heptagon groove, so that the fixed anti-detachment post 4 needs to be rotated by a special tool that matches the regular heptagon groove, preventing non-staff from rotating and disassembling the fixed anti-detachment post 4.

[0034] Embodiment 3:

[0035] The difference from Embodiment 1 is that the regular hexagon groove of the fixed bearing post 7 can also be set as a regular heptagon groove, so that the fixed bearing post 7 needs to be rotated by a special tool that matches the regular heptagon groove, preventing non-staff from rotating and disassembling the fixed bearing post 7.
