[0015] The one side of external thread rod 13 is fixedly connected with connecting rod 14, the one side of connecting rod 14 penetrates to the outside of fixed seat 2 and is fixedly connected with driven wheel 15, the top of fixed seat 2 is fixedly installed with reciprocating motor 16, the output end of one side of reciprocating motor 16 is fixedly connected with driving wheel 17, the surface of driving wheel 17 and driven wheel 15 is drivingly connected with transmission belt 18.
[0016] The top position and the bottom position in movable groove 6 are fixedly connected with support rod 12, and support rod 12 is sleeved with circular movable plate 7 and is slidably connected.
[0017] The inside of fixed seat 2 is equipped with sliding groove 9 corresponding to the top and bottom of movable groove 6, and the top and bottom of circular movable plate 7 are fixedly connected with sliding block 10, and the one side of sliding block 10 away from circular movable plate 7 penetrates to the inside of sliding groove 9 and is slidably connected with sliding groove 9.
[0018] The front side position and the rear side position of the top of base 1 are equipped with moving groove 20, and the inside of moving groove 20 is rotatably connected with screw thread rotating rod 21, and the one side of screw thread rotating rod 21 is screw threadedly connected with screw thread sleeve plate 23, and the top of screw thread sleeve plate 23 penetrates to the outside of base 1 and is fixedly connected with the bottom of movable seat 4, and the top position of the other side of base 1 is fixedly installed with variable frequency motor 22, and the output end of one side of variable frequency motor 22 penetrates to the inside of moving groove 20 and is fixedly connected with screw thread rotating rod 21.
[0019] The center of the top of the base 1 is provided with a blanking groove 19.
[0020] Working principle: when the plastic bottle injection molding is needed, start the variable frequency motor 22. The output end of the variable frequency motor 22 drives the threaded rotating rod 21 to rotate. Since the threaded rotating rod 21 is screwed with the threaded sleeve plate 23, and the threaded sleeve plate 23 is limited by the movable seat 4 and the base 1, it can only move linearly along the moving groove 20. Therefore, under the rotation of the threaded rotating rod 21, the threaded sleeve plate 23 will move along the moving groove 20 towards the fixed seat 2, and the movement of the threaded sleeve plate 23 drives the movable seat 4 to move synchronously, so that the concave injection mold base 5 gradually approaches the convex mold base 3, and finally realizes the clamping of the mold, providing a closed cavity for the injection molding of the plastic bottle. When the plastic bottle is formed in the cavity, the injection molding system stops working, the variable frequency motor 22 reverses rotation, driving the threaded rotating rod 21 to reverse rotation, and the threaded sleeve plate 23 moves away from the fixed seat 2 under the reverse rotation of the threaded rotating rod 21, thereby driving the movable seat 4 to move, so that the concave injection mold base 5 is separated from the convex mold base 3, preparing for demolding operation. Start the reciprocating motor 16, the output end of the reciprocating motor 16 drives the driving wheel 17 to rotate, and the driving wheel 17 drives the driven wheel 15 to rotate through the transmission belt 18. Since the driven wheel 15 is fixedly connected with the connecting rod 14, and the connecting rod 14 is fixedly connected with the outer threaded rod 13, the rotation of the driven wheel 15 will drive the outer threaded rod 13 to rotate in the movable groove 6. The center of the circular movable plate 7 is provided with an internal thread 11, and the outer threaded rod 13 is sleeved with the circular movable plate 7 and screwed with the outer threaded rod 13 through the internal thread 11. At the same time, the circular movable plate 7 is limited by the supporting rod 12 and can only move linearly along the supporting rod 12, and the sliders 10 at the top and bottom of the circular movable plate 7 slide in the sliding groove 9, further ensuring the stability of the linear motion of the circular movable plate 7. Under the rotation of the outer threaded rod 13, the circular movable plate 7 will move away from the fixed seat 2 along the outer threaded rod 13, driving the annular top plate 8 to move synchronously. One end of the annular top plate 8 penetrates to the outside of the fixed seat 2. When it moves, it will push the molded plastic bottle out of the convex mold base 3, realizing demolding operation. The demolded plastic bottle falls from the opening of the fixed seat 2 under the pushing of the annular top plate 8 and the action of its own gravity. The center of the top of the base 1 is provided with a blanking groove 19. The plastic bottle falls into the blanking groove 19 after falling, and the subsequent plastic bottle in the blanking groove 19 can be conveyed to the next process through the corresponding conveying device, completing the whole blanking process.
[0021] In summary: the blanking device of the injection molding machine for plastic bottles, by setting the movable groove 6 in the fixed seat 2, and setting the slidable circular movable plate 7 in the movable groove 6, the circular movable plate 7 is connected with the annular top plate 8 on one side, when the reciprocating motor 16 is started, the output end drives the driving wheel 17 to rotate, the driving wheel 17 drives the driven wheel 15 to rotate through the transmission belt 18, and then drives the external thread rod 13 to rotate, because the circular movable plate 7 is screwed with the external thread rod 13 through the internal thread 11, and the circular movable plate 7 is limited by the supporting rod 12, can only move linearly along the supporting rod 12, so when the external thread rod 13 rotates, the circular movable plate 7 will drive the annular top plate 8 to move outward, and the formed plastic bottle is ejected from the convex mold seat 3, realizing automatic demolding, this process does not need manual operation, greatly reducing the labor intensity of the operator, the demolded plastic bottle can directly fall from the opening of one side of the fixed seat 2 under the action of gravity, and fall into the blanking groove 19 on the top of the base 1, realizing automatic blanking, the whole process is highly automated, avoiding the cumbersome operation of manual blanking, the reciprocating motor 16 can provide stable and fast power output, so that the moving speed and force of the annular top plate 8 are controllable, the plastic bottle can be ejected from the mold in a short time, greatly improving the demolding efficiency, compared with manual demolding, automatic demolding is not affected by the skill level and fatigue degree of the operator, the action and force of each demolding can remain consistent, thereby ensuring the consistency of the demolding effect.
