[0036] The working principle of an injection mold with an inner ejection mode provided by the utility model is as follows: when the injection mold is needed to be used to injection mold automobile parts, the parts raw materials are first placed in the lower mold 5, and then the hydraulic cylinder 8 is started to drive the upper mold 9 to move in the direction close to the lower mold 5 until the automobile parts are extruded and formed. When the automobile parts need to be quickly demolded after extrusion and forming, the cylinder 302 is first started to drive the ejector block 303, and the ejector block 303 drives the disc to rotate with the help of the connecting rod 304, and the disc drives the screw rod 305 to rotate. When the screw rod 305 rotates, it will drive the connecting plate 307 to move in the direction close to the lower mold 5, and the connecting plate 307 drives the ejector rod 308, so that the parts in the lower mold 5 can be ejected with the help of the ejector rod 308. After the parts are ejected, the cylinder 302 is started to drive the ejector block 303 to move in the direction, so that the screw rod 305 can rotate in the opposite direction, and the screw rod 305 drives the connecting plate 307, and the connecting plate 307 drives the ejector rod 308 to return to its original position. The parts in the lower mold 5 can be quickly ejected. When the screw rod 305 drives the connecting plate 307 to move, the ear plate 310 fixed on the connecting plate 307 will move along the arc surface of the positioning rod 311, thereby achieving the effect of improving the stability of the connecting plate 307 during movement. In addition, when the connecting plate 307 drives the ejector rod 308 to move downward and just blocks the gap between the lower mold 5 and the ejector rod 308, one side of the positioning plate 309 will fit with the lower surface of the connecting plate 307, thereby achieving the effect of quickly positioning the connecting plate 307, so that the connecting plate 307 can be quickly reset. Finally, by setting the screw rod 305 to stainless steel, the service life of the screw rod 305 can be effectively improved. By setting the adjustment structure 3, after the injection molding of the automobile parts, the ejector rod 308 can be automatically adjusted to eject the automobile parts in the lower mold 5, without the need for manual demoulding by personnel, thereby improving the demoulding efficiency and the processing efficiency of automobile parts.

[0037] When it is necessary to adjust the scraper 46 to scrape off the burrs generated after the injection molding and stamping of the automobile parts, the adjusting ring 45 is first rotated to move along the arc surface of the slide rod 44, so that the adjusting ring 45 drives the rubber pad 48 to separate from the slide rail 41, and then the handle 47 is moved to drive the sliding frame 43, and the sliding frame 43 drives the scraper 46, and the burrs on the automobile parts can be scraped off with the help of the scraper 46. When the scraper 46 is used, the handle 47 is moved to drive the sliding frame 43 to move to one side of the slide rail 41, and the adjusting ring 45 is rotated again to drive the rubber pad 48 to abut against the slide rail 41, so that the scraper 46 can be stored and fixed. Among them, the rubber pad 48 can increase the friction force on one side of the adjusting ring 45, so that the adjusting ring 45 can abut against the slide rail 41 to ensure a stable effect. By setting the auxiliary structure 4, after the injection molding of the automobile parts is completed, the personnel can easily adjust the scraper 46 to clean the burrs on the surface of the parts, thereby improving the injection molding quality of the parts.
