[0005] Preferably, the outer wall of the pin is in contact with the inner wall of the fixing groove, and the limiting rod is configured with a trapezoidal structure.

[0006] Preferably, the outer wall of the limiting rod is in contact with the inner wall of the limiting groove, and the outer wall of one end of the pin is adapted to the inner wall of the first pin hole.

[0007] Preferably, a side plate is fixedly connected to one side of the lower mold, a second pin hole is provided through the top of the side plate, a bolt is threaded to the inner side of the base, an anti-detachment plate is fixedly connected to the outer side of the bolt, a fixing hole is slidably connected to the outer side of the anti-detachment plate, a convex ring is fixedly connected to the outer side of the bolt, and a pressure plate is rotatably connected to the top of the convex ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-install hole mold, during installation, involves pulling the pin upwards, compressing the second spring, and then sliding the lower mold and the limiting rod together until one end of the pin coincides with the first pin hole. Releasing the pin causes the second spring to return, and one end of the pin inserts into the first pin hole, thus pre-fixing the lower mold. The pipe fitting to be punched is placed into the lower mold, and then the upper mold is pushed down by a cylinder, through which a through-hole is formed, thus opening the pipe fitting. This also facilitates fixing or replacing the lower mold. After pre-fixing, pressing the bolt causes the threaded section of the bolt to connect to the base, thereby pushing down the pressure plate. One end of the pressure plate inserts into the second pin hole, further fixing the lower mold. Attached Figure Description
