[0036] Referring to Figure 1 - Figure 3The lifting assembly 3 comprises a support plate 301, a motor 302 and a threaded rod 303. The outer surface of the support plate 301 is fixedly connected to the rear end of the outer surface of the lower mold 1, thereby providing a fixed support effect for the support plate 301. The outer surface of the motor 302 is fixedly connected to the top end of the outer surface of the support plate 301, thereby providing a fixed support effect for the motor 302. The output end of the motor 302 is fixedly connected with the threaded rod 303, so that the motor 302 can drive the threaded rod 303 to rotate.

When the upper mold 2 is descending and the traction rod 5 stops pressing against the bottom of the extrusion rod 4, the ejector B12 moves upward and resets due to the elastic force of spring A14. One end of spring B17 is fixedly connected to the top of the inner surface of the ejector A10, and the other end of spring B17 is fixedly connected to the top of the outer surface of the column B15. When the U-shaped rod 6 rises and the column B15 stops limiting the inside of the ejector A10, the ejector A10 can be directly connected to spring B17, so that the ejector A10 has spring properties and can buffer the mold falling from the upper mold 2.

[0039] Reference Figure 1 - Figure 2 , Figure 4 Both the top of the outer surface of column A13 and the top of the outer surface of column B15 are fixedly connected to discs, allowing the discs on column A13 to provide support points for spring A14, enabling spring A14 to drive column A13 to move upwards. The disc on column B15 is designed to contact the bottom of the inner surface of ejector A10 when U-shaped rod 6 descends to the bottom of the lower mold 1, thus fixing ejector A10 in a designated position. A damping column 16 is fixedly connected to the top of the outer surface of column B15, allowing column B15 to move vertically while simultaneously moving the damping column 16. The top of the outer surface of the damping column 16 is connected to the top of the ejector A15. The inner surface of 10 is slidably connected, allowing the damping column 16 to move vertically along the inner surface of the ejector A10. The top of the outer surface of the damping column 16 is provided with damping texture. When the mold falls onto the ejector A10, the damping texture on the damping column 16 will cause the ejector A10 to stop quickly and buffer the shaking of the mold. The top of the outer surface of the upper mold 2 is provided with an injection hole 18, which allows the injection material to be injected into the upper mold 2 and the lower mold 1 when they are closed. The column A13 and column B15 are each provided with three sets, which can provide a more stable effect when the column A13 and column B15 drive the ejector B12 and ejector A10.

[0040] Working principle: when the injection molding is completed, the motor 302 reverses to drive the threaded rod 303 to rotate, so that the upper mold 2 moves upward, and when the upper mold 2 rises, the traction rod 5 will be in contact with the bottom end of the extrusion rod 4 fixed on the top of the support plate 301 to extrude, thereby driving the ejector B12 to move downward, and the mold adhering to the inside of the upper mold 2 is ejected, when the upper mold 2 continues to rise, the top end of the moving block 9 will be in contact with the bottom end of the traction block 7, thereby driving the U-shaped rod 6 to move upward, and after the U-shaped rod 6 rises, the cylinder B15 will stop limiting the inside of the ejector A10, and at the same time drive the ejector A10 to move upward, the mold adhering to the inside of the lower mold 1 is ejected, and the ejector A10 will be supported by the spring B17, which has a spring property under the action of the spring B17, so that when the mold after injection molding falls from the upper mold 2 to the ejector A10, the ejector A10 can buffer the mold, at the same time, the damping column 16 on the cylinder B15 will move along the inner surface of the ejector A10, so that the damping pattern on the top of the outer surface of the damping column 16 can make the ejector A10 stop quickly due to the shaking caused by the buffering of the mold, thereby realizing the automatic demolding of the automobile precision mold.

[0041] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
