[0023] Furthermore, a lifting column is fixedly connected to the middle part of the lower end of the lower mold 2, and the lower end of the lifting column extends through the interior of the lower mold base 1 to the rectangular groove 101 and fixes the lower end face of the lifting column to the upper end face of the airbag 102. The lower mold 2 is lifted up to a certain height in the mold groove 103 through the airbag 102, and the upper and lower pressing ends 402 of the upper mold 4 press down the pressure-bearing end face 202, so that the lower mold 2 descends and compresses the airbag 102, and the lower mold 2 is completely retracted into the mold groove 103.

[0024] Furthermore, rectangular limiting grooves 104 are provided in the middle of both sides and the middle of both front and rear ends of the mold groove 103, and rectangular limiting parts 201 are fixedly connected in the middle of both sides and the middle of both front and rear ends of the lower mold 2.

[0025] Furthermore, the rectangular limiting portion 201 on the lower mold 2 slides into the rectangular limiting groove 104 for limiting connection, so that the lower mold 2 remains stable when moving in the mold groove 103 .

[0026] Furthermore, a spring 205 is provided at the lower end of the ejection mechanism 3 inside the circular groove 203 , and two L-shaped push rods 301 are respectively placed in the rectangular lifting grooves 204 , and the upper end of one side of the L-shaped push rod 301 passes through the lower mold 2 and extends to the pressure-bearing end surface 202 .

[0027] Furthermore, when the upper mold 4 presses down the lower mold base 1 , the pressing end 402 is in contact with the pressure-bearing end surface 202 of the lower mold 2 .

[0028] Furthermore, the upper end of the ejection mechanism 3 passes through the upper opening of the circular groove 203 and extends into the injection groove 401. When the upper mold 4 descends, the lower pressing end 402 first contacts the upper ends of the two L-shaped push rods 301 and presses down the upper ends of the two L-shaped push rods 301. The two L-shaped push rods 301 descend in the rectangular lifting groove 204 and jointly pull the ejection mechanism 3 to descend in the circular groove 203, while compressing the spring 205. When the upper end surfaces of one side of the two L-shaped push rods 301 descend and are parallel to the pressure-bearing end surface 202, the upper end surface of the ejection mechanism 3 coincides with the upper end surface of the lower mold 2. When the lower mold 2 is completely retracted into the mold groove 103, injection molding can be performed.

[0029] Working principle: When in use, the upper mold 4 descends and presses down the lower mold base 1. When the upper mold 4 descends, the lower pressing end 402 first contacts the upper ends of the two L-shaped push rods 301 and presses down the upper ends of the two L-shaped push rods 301. The two L-shaped push rods 301 descend in the rectangular lifting groove 204 and jointly pull the ejection mechanism 3 to descend in the circular groove 203, while compressing the spring 205. When the upper end surfaces of one side of the two L-shaped push rods 301 descend and are parallel to the pressure end surface 202, the upper end surface of the ejection mechanism 3 coincides with the upper end surface of the lower mold 2, and the upper and lower pressure ends 402 of the upper mold 4 press down the pressure end surface 202. The end surface 202 is pressed to make the lower mold 2 descend and compress the airbag 102, and the lower mold 2 is completely retracted into the mold groove 103, and injection molding can be carried out. After the injection molding is completed, the upper mold 4 is separated, and the lower mold 2 is lifted up to a certain height in the mold groove 103 by the airbag 102, so that the injection-molded product is lifted in the mold groove 103, which is convenient for taking the product. At the same time, the spring 205 pushes the ejection mechanism 3 to extend out of the circular groove 203, so that the ejection mechanism 3 lifts the product from the upper end surface of the lower mold 2, separates the product from the lower mold 2, and makes it more convenient to take the product.
