[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0020] like Figure 1-3As shown, a drilling and positioning fixture for a demolding guide sleeve includes a base plate 1, which has a square structure. The base plate 1 has positioning holes 11 and positioning blocks 2, which are symmetrically connected to the base plate 1. Specifically, the base plate 1 has threaded holes 12, and the lower end of the positioning blocks 2 has a threaded section 21 that is threadedly connected to the threaded holes 12. The sides of the positioning blocks 2 are rounded. The positioning blocks 2 can be embedded into the guide holes 61 of the demolding guide sleeve 6 for positioning and initial fixation of the demolding guide sleeve 6. Furthermore, the positioning blocks 2 are easy to assemble and disassemble; the corresponding positioning blocks 2 can be replaced according to the size of the guide holes 61, making assembly and disassembly of the positioning blocks 2 more convenient. A clamping mechanism 3 is provided on the side of the base plate 1 away from the positioning block 2. The clamping mechanism 3 includes a locking block and a locking screw 32. The locking block has a "C" shaped structure and includes a locking part 311, a pressing part 312 and a connecting part 313. The locking part 311 and the pressing part 312 are respectively connected to the upper and lower ends of the connecting part 313. The locking part 311 and the connecting part 313 are horizontally arranged. A slot is formed between the locking part 311, the connecting part 313 and the pressing part 312. The slot can be snapped onto the side of the base plate 1 and the demolding guide sleeve 6. The locking part 311 is threadedly connected to the locking screw 32.
