[0025] Embodiment 2

[0026] Please refer to Figures 1-3 As shown in FIGS. 5, a limiting groove 25 is formed on the right side of the sliding plate 6. A limiting plate 26 is fixedly installed on the left side of the ejector pin 9. A clamping groove A 27 is formed on the surface of the limiting plate 26. A clamping groove B 28 is formed on the surface of the sliding plate 6. A groove 29 is formed on the surface of the clamping groove B 28. A clamping rod 30 is slidably connected inside the clamping groove B 28. A blocking block 31 is fixedly installed on the surface of the clamping rod 30. A pinching groove 32 is formed on the surface of the blocking block 31. It is more convenient to replace the ejector pin 9 after long-term use. After long-term use, the staff can pinch the pinching groove 32 and pull it backward, so that the blocking block 31 slides backward inside the sliding plate 6 through the groove 29, and drives the clamping rod 30 to slide backward inside the sliding plate 6 through the clamping groove B 28. When the clamping rod 30 slides out of the inside of the sliding plate 6 through the clamping groove B 28 and completely slides out of the inside of the limiting plate 26 through the clamping groove A 27, then pinch the limiting plate 26 and pull it to the right, so that the limiting plate 26 slides out of the inside of the sliding plate 6 through the limiting groove 25 and then the replacement can be carried out, thereby preventing the situation that the ejector pin 9 cannot continue to be used due to damage after long-term use. The limiting plate 26 is slidably connected to the sliding plate 6, the clamping rod 30 is slidably connected to the sliding plate 6, the clamping rod 30 is slidably connected to the limiting plate 26, and the blocking block 31 is slidably connected to the sliding plate 6, which is more convenient for the clamping rod 30 to slide and avoid the situation that the clamping rod 30 cannot continue to slide due to being stuck by the sliding plate 6 or the limiting plate 26 during use.

[0027] Working principle: When in use, first fixedly install the fixed plate 4 on the device, connect the sliding plate 6 to the output end of the device through the output slot 5, and then fix the sliding cover 13 on the other end of the device. During the use process, the device drives the sliding cover 13 to slide towards the mold body 1, and the sliding rod B12 slides towards the left inside the mold body 1 through the sliding slot B11. When the injection block 14 completely slides into the mold body 1 through the injection port 10, injection can be carried out through the diversion port 24 and the diversion groove 15. After the injection is completed and the sliding cover 13 is completely opened, at this time, the sliding plate 6 can be pushed towards the mold body 1 through the output slot 5, so that the sliding rod A7 slides inside the mold body 1 through the sliding slot A2, and the spring 8 slides and contracts on the surface of the sliding rod A7, and the ejector pin 9 slides inside the mold body 1 through the sliding slot 3, and the cooled object is ejected from the mold body 1 through the injection port 10 for the staff to take. After long-term use, when it is necessary to clean the inside of the diversion port 24 and the diversion groove 15, first pinch the rotating handle 20 to rotate, so that the threaded rod 19 rotates backward inside the fixed block 17 through the rotating slot 18. When the threaded rod 19 completely rotates out of the fixed block 17 through the rotating slot 18 and out of the inside of the clamping block 22 through the fixed slot 23, then pinch the clamping block 22 and pull it to the right, so that the clamping block 22 slides to the right inside the mounting block 16 through the mounting slot 21. When the clamping block 22 completely slides out of the mounting block 16 through the mounting slot 21, the diversion port 24 and the diversion groove 15 can be cleaned. And when the ejector pin 9 is damaged and needs to be replaced, the stopper 31 can be pulled backward through the pinch groove 32, so that the stopper 31 slides backward inside the sliding plate 6 through the groove 29, and drives the clamping rod 30 to slide backward inside the sliding plate 6 through the slot B28. When the clamping rod 30 completely slides out of the sliding plate 6 through the slot B28 and out of the inside of the limiting plate 26 through the slot A27, then pinch the limiting plate 26 and pull it to the right, so that the limiting plate 26 slides to the right inside the sliding plate 6 through the limiting slot 25. When the limiting plate 26 completely slides out of the sliding plate 6 through the limiting slot 25, the replacement can be carried out.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
