[0025] like Figures 1-4 As shown, a moving and stationary mold ejection mechanism for automotive sunroof injection molded parts includes:

[0026] Fixed mold body 101, with a cavity 102 at its top and a mating cavity 103 at its bottom; movable mold body 201, with a filler 202 at its bottom center. In use, the fixed mold body 101 is mounted on a base, and the movable mold body 201 is mounted on a movable frame. The movable frame drives the movable mold body 201 to move up and down. When the movable mold body 201 moves down and presses against the top of the fixed mold body 101, the filler 202... The bottom of 02 is attached to the bottom surface of the docking cavity 103, so that the periphery of the cavity 102 and the periphery of the filler 202 are spaced to form the injection cavity 203. The moving mold body 201 is provided with a feeding channel 204 that communicates with the injection cavity 203. At this time, the molten plastic can be fed into the injection cavity 203 along the feeding channel 204, so that the molten plastic fills the injection cavity 203. After the molten plastic in the injection cavity 203 cools and solidifies, the sunroof frame product can be obtained.

[0027] There are two actuating components, which are respectively installed at the bottom of the opposite side of the recess 102 through the first mounting cavity and are located in the injection cavity 203 area; the first mounting cavity includes a snap-fit ​​groove 301, which is installed at the bottom of the recess 102 and is located in the injection cavity 203 area, and the bottom of the snap-fit ​​groove 301 is provided with a receiving groove 302.

[0028] The jacking component includes a mounting frame 501 and a jacking body 502. The mounting frame 501 is securely mounted in the snap-fit ​​groove 301 to prevent it from falling out. The jacking body 502 is movably snapped into the mounting frame 501 and housed within the receiving groove 302. A limiting groove 504 is provided on the jacking body 502. A limiting strip 503 passes through the mounting frame 501 and is located within the limiting groove 504. The bottom wall of the limiting strip 503... A return spring 505 is provided between the limit groove 504 and the bottom wall. The return spring 505 can push the actuating body 502 downward, so that the actuating body 502 can remain in the mounting frame 501 and the receiving groove 302 when it is not pushed upward by external force, thus preventing the actuating body 502 from extending out of the top of the mounting frame 501. A protrusion 506 is provided on the bottom side of the actuating body 502. The protrusion 506 can be used in conjunction with the inclined wall block 602 in the adjusting component.

[0029] There are two adjustment components, which are respectively installed in the fixed mold body 101 through the second mounting cavity and located below the corresponding pusher component. The second mounting cavity includes an assembly groove 401 and a stepped hole 402. The assembly groove 401 and the stepped hole 402 are both installed through the fixed mold body 101. One end of the assembly groove 401 extends to the outside of the back side wall of the fixed mold body 101, and the top of the other end is connected to the receiving groove 302. One end of the stepped hole 402 extends to the outside of the front side wall of the fixed mold body 101.

[0030] The adjusting components include a sealing block 601 and an inclined wall block 602. The sealing block 601 is detachably installed at the back opening of the assembly groove 401, thus sealing the back opening of the assembly groove 401 and limiting the return distance of the inclined wall block 602. The inclined wall block 602 is slidably installed inside the assembly groove 401, and its inclined wall abuts against the protrusion 506. A pull rod 603 is provided on the side of the inclined wall block 602 away from the sealing block 601, and the pull rod 603 is located in the stepped hole 40. Inside 2, a return spring 604 is provided on the pull rod 603 located between one side of the inclined wall block 602 and the stepped wall of the stepped hole 402. The return spring 604 can abut against the inclined wall block 602 and move it closer to the sealing block 601. A handle 605 is detachably provided at the end of the pull rod 603 that extends through to the outside of the front side wall of the fixed mold body 101. The handle 605 can easily pull the pull rod 603, so that the inclined wall block 602 moves away from the sealing block 601.

[0031] After the molten plastic in the injection cavity 203 cools and solidifies, the moving mold body 201 is moved upward by the moving frame, causing it to move away from the top of the fixed mold body 101. Simultaneously, the filler 202 is moved out of the cavity 102. At this point, by holding the handle 605 and pulling it, the pulling rod 603 moves, causing the inclined wall block 602 to move away from the sealing block 601. This compresses and stores the return spring 604, allowing the inclined wall block 602 to move away from the sealing block 601. During the movement in direction 1, the inclined wall of the inclined block 602 and the protrusion 506 are squeezed, causing the abutting and pushing body 502 to move upward, which compresses and stores the return spring 505. During the upward movement of the pushing body 502, the pushing body 502 can push most of the sunroof injection molded part out of the injection cavity 203, so that a large gap space is created between the bottom of the sunroof injection molded part and the bottom of the injection cavity 203. Then the worker can hold the bottom of the sunroof injection molded part and quickly take it out of the injection cavity 203, which improves work efficiency.

[0032] After the part is removed, the pull rod 603 is released. At this time, the compressed and stored return spring 604 rebounds and pushes against the inclined wall block 602, causing it to move closer to the sealing block 601, so as to release the upward pushing action of the inclined wall block 602 on the jacking body 502. At this time, the compressed and stored return spring 505 rebounds and pushes the jacking body 502 downward, finally causing the inclined wall block 602 and the jacking body 502 to move back to their original positions for use in the next manufacturing process.

[0033] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
