The moving rod 3 penetrates the core mold 2 and is slidably connected to the cavity mold 1. It also includes a first mounting frame 4, a pull rope 5, a pulley 6, a directional wheel 601, a placement rod 7 and a first elastic member 8. The first mounting frame 4 is installed at the bottom of the cavity mold 1 by bolt connection. The first mounting frame 4 is slidably connected to the first mounting frame 4. Two placement rods 7 for receiving the model are provided, and the two slide up and down along the first mounting frame 4. A directional wheel 601 is rotatably provided at the bottom of the first mounting frame 4, and a pulley 6 is rotatably provided at the bottom of the core mold 2. A pull rope 5 is fixedly connected to the bottom of the core mold 2 and the bottom of the placement rod 7 by a rope knot, and the pull rope 5 is guided by the pulley 6 and the directional wheel 601. An arc transition surface is provided at the bottom of the placement rod 7 to reduce the friction between the placement rod 7 and the pull rope 5 to prevent the pull rope 5 from being worn and broken, thereby extending the service life of the pull rope 5. A first elastic member 8 is wound around the lower part of the placement rod 7, and the first elastic member 8 is used to push the placement rod 7 to slide downward and reset.

[0026] When it is necessary to perform injection molding of the mold 201 of the needle holder clamp of the needle aid, the core mold 2 is pushed to slide on the cavity mold 1 through the moving rod 3, so that the core mold 2 fits with the cavity mold 1, and the mold 201 is embedded in the molding groove 101. At this time, the drawstring 5 is loosened, and the first elastic member 8 pushes the placement rod 7 to slide downward along the first mounting frame 4. The drawstring 5 is passed through the pulley 6 and the directional wheel 601 to rotate the pulley 6 and the directional wheel 601, and then injection molding is performed from one side of the cavity mold 1 into the molding groove 101, so that the needle holder clamp of the needle aid is The needle holder clamp model is formed; then the core mold 2 is pulled to the side away from the cavity mold 1, so that the needle holder clamp model is sleeved on the mold 201 and is moved and taken out with the core mold 2. At this time, the pulley 6 and the directional wheel 601 are guided to make the pull rope 5 pull the placement rod 7 to slide upward along the first mounting frame 4. At this time, the first elastic member 8 is compressed and deformed by force, and the placement rod 7 approaches the mold 201. The needle holder clamp model on the mold 201 falls and is sleeved on the placement rod 7 for automatic material collection.

[0027] Example 2: Based on Example 1, refer to Figure 3As shown, it also includes a push rack 13 slidably arranged in the middle of the core mold 2, the push rack 13 penetrates and is slidably connected to the mold 201, the side of the push rack 13 away from the cavity mold 1 is fixedly connected with two guide rods 12 by welding, the side of the two guide rods 12 away from the push rack 13 is jointly fixedly connected with a guide plate 9 by welding, and two second elastic members 14 are jointly fixedly connected between the push rack 13 and the core mold 2 by welding, a through hole 10 for passing the ejector pin is opened on the side of the core mold 2 away from the cavity mold 1, and a positioning groove 11 for accommodating the ejector pin is opened on the side of the guide plate 9 away from the guide rod 12.

[0028] When the core mold 2 is pulled to move toward the side away from the cavity mold 1, the ejector pin of the injection molding machine enters the positioning groove 11 through the through hole 10 and holds the guide plate 9. The guide plate 9 keeps the push frame 13 stationary through the guide rod 12. As the core mold 2 continues to move, the second elastic member 14 is compressed and deformed by the force, so that the push frame 13 pushes down the needle holder clamp model of the needle aid mounted on the mold 201 to demold the model; when the core mold 2 moves toward the side close to the cavity mold 1, the second elastic member 14 returns to its original state and pushes the push frame 13 to slide and reset.

[0029] See also Figure 4 As shown, it also includes a second mounting frame 15 installed at the lower side of the cavity mold 1 by means of bolt connection, and a fan 16 is installed on the second mounting frame 15 by means of bolt connection. The air outlet of the fan 16 faces the placement rod 7, and a condenser 17 for cooling the air is installed in the fan 16 by means of bolt connection.

[0030] When the model is demoulded, the fan 16 is started to blow air toward the needle holder clamp model, and the blown air is cooled by the condenser 17 to cool the needle holder clamp model on the placement rod 7, so that the model is cooled and solidified.
