Since the rack 9 inside the movable frame 8 moves back and forth during the reciprocating movement of the movable frame 8 up and down, the sleeve 10 is driven to rotate through the first gear 12 and the second gear 20, and the sleeve 10 drives the fan blade 11 to rotate, and the finished wire reel is cooled while the material is automatically withdrawn.
[0023] A first groove 13 is provided on the upper surface of the rack 9, and a first slide rod 14 is slidably connected inside the first groove 13. The first slide rod 14 is fixedly connected to the movable frame 8. Since the rack 9 needs to slide back and forth in the movable frame 8, the rack 9 is guided by the first groove 13 and the first slide rod 14, and the rack 9 is also limited to ensure that the rack 9 is always engaged with the second gear 20.
[0024] The corresponding two side edges of the movable frame 8 are provided with second grooves 15, and the second sliding rod 16 is slidably connected inside the second groove 15. The second sliding rod 16 is fixedly connected to the bracket 2. The movable frame 8 can slide back and forth up and down in the bracket 2. The second groove 15 and the second sliding rod 16 ensure the stability of the movable frame 8 when it slides back and forth up and down.
[0025] A through slot 17 is provided inside the bottom plate 1 for dropping materials. When the sleeve 10 pushes the finished wire reel on the core rod 5 off, the finished wire reel will fall directly through the through slot 17 , and the user can collect the finished wire reel directly under the through slot 17 .
[0026] The utility model uses the following steps: when the polymer plastic welding wire reel injection molding mold is in use, after the injection molding is completed, the cylinder 3 is started to drive the mold body 4 away from the core rod 5. At this time, the two mold bodies 4 are completely opened, and the finished welding wire reel will be left on the core rod 5. The motor 6 is started to drive the rotating plate 7 to rotate, and the rotating plate 7 drives the rack 9 to make a circular motion. The rack 9 is limited by the movable frame 8, and the movable frame 8 is limited by the bracket 2. Therefore, when the rotating plate 7 rotates, the rack 9 will slide back and forth inside the movable frame 8. When the movable frame 8 slides downward, the sleeve 10 is driven to push down the finished welding wire reel remaining on the core rod 5 from top to bottom until the finished welding wire reel is separated from the core rod 5 and falls, thereby realizing automatic material withdrawal. When the rack 9 slides back and forth left and right in the movable frame 8, the sleeve 10 is also driven to rotate through the first gear 12 and the second gear 20, and the sleeve 10 drives the fan blade 11 to rotate, so as to cool down the finished welding wire reel before pushing it down. Example 2
[0027] The existing molding mold drives the mold body 4 to slide back and forth on the base plate 1 through the cylinder 3. Since the lower surface of the mold body 4 is directly in contact with the upper surface of the base plate 1, significant wear will occur between the mold body 4 and the base plate 1 after long-term use. This problem is solved by the following solution.
[0028] See also Figures 1 to 3The difference between the combined implementation basis is that the bottom of the mold body 4 is rotatably connected with a ball 18. There are four ball 18 in total, and the four ball 18 are symmetrically distributed. The ball 18 reduces the friction between the mold body 4 and the bottom plate 1, so that the cylinder 3 drives the mold body 4 to move back and forth more smoothly. The ball 18 is arranged at the four corners of the bottom of the mold body 4.
[0029] A slide groove 19 is provided on the upper surface of the base plate 1, and the slide groove 19 is used in conjunction with the ball 18. The ball 18 and the slide groove 19 can guide the mold body 4 to prevent the mold body 4 from swinging back and forth when the cylinder 3 drives the mold body 4 to move, resulting in the two mold bodies 4 being unable to be completely closed.
[0030] Usage steps of the utility model: When the polymer plastic welding wire reel injection molding mold is in use, the cylinder 3 drives the mold body 4 to move back and forth on the base plate 1, so that the two mold bodies 4 are close to or away from each other. During the process, the ball 18 at the bottom of each mold body 4 will roll in the slide groove 19 set on the upper surface of the base plate 1, and the mold body 4 is limited by the ball 18 and the slide groove 19, so that the two mold bodies 4 can move more smoothly while preventing them from swinging, and can prevent excessive wear between the mold body 4 and the base plate 1.
