DETAILED IMPLEMENTATION MANNER

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , a forming die for a bent blade, including two side plates 1, a plurality of guide rods 2 fixedly connected between the two side plates 1, a die one 3 and a die two 4 are slidably sleeved on the guide rods 2, and pouring ports 9 are opened on both the die one 3 and the die two 4, and molten metal is added into the die one 3 and the die two 4 through the pouring ports 9.

[0018] A die pushing module 5 is installed on one of the side plates 1, and the die pushing module 5 is connected to the die one 3. Specifically, the die pushing module 5 includes a crank 51, the crank 51 is fixedly connected with a threaded rod 52, the threaded rod 52 is screwed into the side plate 1, a sleeve 54 is sleeved outside the threaded rod 52, a limit head 53 is arranged at the end of the threaded rod 52, and the sleeve 54 is fixedly welded to the outer wall of the die one 3. By rotating the crank 51, the threaded rod 52 can be rotated, so that the top of the threaded rod 52 drives the die one 3 to move.

[0019] A motor 6 is arranged on the first mold 3. A cam is fixed to the driving end of the motor 6. A side wing plate 7 is correspondingly arranged on the side wall of the second mold 4. A locking and fixing assembly is arranged on the second mold 4. A stripping plate 10 is arranged on the side of the second mold 4 away from the first mold 3. The stripping plate 10 is slidably mounted on the guide rod 2. When the first mold 3 and the second mold 4 need to be separated for demolding, the motor 6 drives the cam to rotate, and the cam continuously strikes the side wing plate 7, and the two molds are separated.

[0020] The locking and fixing assembly is a guide cylinder 8 fixed to the side wall of the second mold 4. A fastening screw is screwed into the guide cylinder 8. By screwing the fastening screw tightly, the second mold 4 is fixed.

[0021] A placing rack 11 is arranged between the two side plates 1. The placing rack 11 is located at the bottoms of the first mold 3 and the second mold 4. A collecting box 12 is arranged on the placing rack 11. The collecting box 12 can collect the castings removed from the mold.

[0022] A plurality of universal wheels 13 are installed at the bottom of the side plate 1. It is convenient to move the whole device.

[0023] Working principle: For a forming mold of a bent blade of the present utility model, in use, turning the crank 51 can rotate the threaded rod 52, so that the top of the threaded rod 52 drives the first mold 3 to move, and the first mold 3 and the second mold 4 are brought together.
