However, in the prior art, for the existing injection molding machine for ABS pipe fittings, the already injection-molded pipe fittings need to be taken out of the mold before the next pipe fitting can be injected, which increases the waiting time in the production process and reduces the production efficiency. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide an injection molding machine for ABS pipe fittings.

[0005] The technical solution of the present utility model is as follows: The injection molding machine for ABS pipe fittings includes a bottom plate. A rotating rod is rotatably connected to the top end of the bottom plate. A turntable is fixedly connected to the top end of the rotating rod. Lower molds symmetrically distributed at the center are fixedly connected to the top end of the turntable. A runner is fixedly connected to the outside of the rotating rod. An arc-shaped groove is formed in the outside of the runner. A U-shaped groove is formed in the outside of the runner and between two adjacent arc-shaped grooves. A stepping motor is fixedly installed on the top end of the bottom plate near the rotating rod. A dial is fixedly connected to the driving end of the stepping motor. A dial rod is fixedly connected to one side of the dial. A limiting column is fixedly connected to the top of the end of the dial rod away from the dial. The limiting column is slidably clamped in the corresponding U-shaped groove. The convex surface of the dial is slidably clamped in the corresponding arc-shaped groove.

[0006] As a preferred embodiment, three support rods are fixedly connected to the top end of the bottom plate, and the bottom end of one of the support rods movably penetrates through the rotating rod, and a top plate is fixedly connected between the top ends of the three support rods.

[0007] As a preferred embodiment, a hydraulic cylinder is fixedly installed at the top end of the top plate, the piston rod of the hydraulic cylinder extends to the bottom end of the top plate and is fixedly connected with a moving plate, the moving plate is slidably clamped outside the support rod, and an upper mold is fixedly installed at the bottom end of the moving plate.

[0008] As a preferred embodiment, a bearing is fixedly installed at the top end of the bottom plate and outside the bottom end of the rotating rod.

[0009] As a preferred embodiment, both the stepping motor and the hydraulic cylinder are electrically connected to an external control device.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are that,

[0011] In the present utility model, the dial is driven to rotate by the stepping motor. When the dial rotates to the arc surface sliding along the inner wall of the arc groove, at this time, the arc groove is in a static state. At this time, the piston rod of the hydraulic cylinder extends, pushing the upper mold to move towards one side of the lower mold to realize mold closing for injection molding and mold opening for forming. When the dial rotates to the limiting column being clamped into the U-shaped groove, the rotating wheel is driven to rotate at the same time, so that an adjacent lower mold rotates to the lower part of the upper mold. At this time, the dial just rotates to control the arc surface to slide along the inner wall of the arc groove. Using the intermittent time, the ABS pipe fittings are injected. While injecting, the already injection-molded ABS pipe fittings can be taken out from the lower mold. Repeat this way to realize continuous injection molding operation, further improving the injection molding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In this embodiment, when injecting the ABS pipe fittings, the stepping motor 8 drives the dial 9 to rotate. When the dial 9 rotates to the arc surface sliding along the inner wall of the arc-shaped groove 6, at this time, the arc-shaped groove 6 is in a static state, and the equipment starts to inject. When the dial 9 rotates to the limiting column 11 being clamped inside the U-shaped groove 7, it simultaneously drives the runner 5 to rotate, so that an adjacent lower mold 4 rotates to the lower part of the upper mold 16. At this time, the dial 9 just rotates to control the arc surface to slide along the inner wall of the arc-shaped groove 6. Using the intermittent time, the ABS pipe fittings are injected. While injecting, the already injection-molded ABS pipe fittings can be taken out of the lower mold 4. Repeat this process to achieve continuous injection operation.

[0021] Three support rods 12 are fixedly connected to the top end of the bottom plate 1. The bottom end of one of the support rods 12 movably penetrates through the rotating rod 2, and a top plate 13 is fixedly connected between the top ends of the three support rods 12.

[0022] By adopting the above technical solution, by setting the support rods 12, the equipment installed on the top plate 13 can be stably supported.

[0023] A hydraulic cylinder 14 is fixedly installed at the top end of the top plate 13. The piston rod of the hydraulic cylinder 14 extends to the bottom end of the top plate 13 and is fixedly connected to a moving plate 15. The moving plate 15 is slidably clamped outside the support rod 12, and an upper mold 16 is fixedly installed at the bottom end of the moving plate 15.

[0024] By adopting the above technical solution, through the telescopic movement of the piston rod of the hydraulic cylinder 14, the moving plate 15 and the upper mold 16 are pushed to move vertically, so as to realize the mold opening and closing operations.

[0025] A bearing 17 is fixedly installed at the top end of the bottom plate 1 and outside the bottom end of the rotating rod 2.

[0026] By adopting the above technical solution, by setting the bearing 17, it is convenient for the rotating rod 2 to rotate well.

[0027] The stepping motor 8 and the hydraulic cylinder 14 are both electrically connected to an external control device.

[0028] By adopting the above technical solution.

[0029] Working principle: When injecting the ABS pipe fittings, the dial 9 is driven to rotate by the stepping motor 8. When the arc surface of the dial 9 slides along the inner wall of the arc groove 6, at this time, the arc groove 6 is in a static state. At this time, the piston rod of the hydraulic cylinder 14 extends, and the upper mold 16 is pushed to move towards the lower mold 4 to realize closed mold injection and open mold forming. When the limiting column 11 of the dial 9 is clamped into the U-shaped groove 7, the runner 5 is driven to rotate at the same time, so that an adjacent lower mold 4 rotates below the upper mold 16. At this time, the dial 9 just rotates to control the arc surface to slide along the inner wall of the arc groove 6. Using the intermittent time, the ABS pipe fittings are injected. While injecting, the already injection-molded ABS pipe fittings can be taken out from the lower mold 4. Repeat this way to realize continuous injection operation.
