[0036] In summary, this high-precision injection mold with automatic ejection structure and strong stability. When in use, the high-pressure jet port 8 is driven down by the multi-stage cylinder 4, and then the high-pressure jet port 8 is opened, and the high-pressure jet is driven by the first motor 7. The port 8 rotates, so that the high-pressure gas sprayed from the high-pressure jet port 8 cleans the upper mold 16 and the lower mold 20. After the cleaning is completed, the second motor 11 controls the rotation of the first gear 12 and the second gear 13 to drive the axle 15 The threaded rod 10 that forms a rotating structure with the fixed bracket 1 rotates, and the position of the upper mold 16 is controlled by the threaded connection between the threaded rod 10 and the threaded block 14, so that the upper mold 16 and the lower mold 20 are butt-connected through the guide hole 21 It is guided with the guide rod 19, so that the lower mold 20 and the upper mold 16 are perfectly connected. The heating resistor 22 is installed on the heating resistor 22 through the drawing structure formed between the clamp block 23 and the lower mold 20, so that the heating resistor 22 is aligned The lower mold 20 is heated, and then the air pump 301 is turned on to extract the air between the upper mold 16 and the lower mold 20 and the solenoid valve 303 is controlled to close the solenoid valve 303. The injection port 17 is used for injection. The ejector rod 1801 is ejected when the equipment is demolded Will withstand the fixed bracket 1, so that the ejector block 1804 ejects the product. When the equipment is used next time, repeat the above steps while relying on the limit block 1802 to eject the product through the elastic structure formed between the return spring 1803 and the upper mold 16 Block 1804 is restored to its original position without affecting the appearance of the product.
