One end of the telescopic rod 504 extends into the sleeve 503 and telescopically cooperates with the sleeve 503, and the other end is fixedly connected to the push rod 403.

[0040] When the male module 202 moves down and enters the female mold cavity 101 for mold closing, the push plate 401 is embedded in the storage groove 102, and the end of the slide bar 501 extends to the inner bottom of the vertical groove 108. When the automobile interior panel in the female mold cavity 101 is cooled and solidified, as the male mold seat 201 and the male module 202 move up, the male mold seat 201 can drive the lifting rod 505 to move up, and the lifting rod 505 drives the push rod 403 to move up through the sleeve 503 and the telescopic rod 504. When the push rod 403 moves up, it drives the slide bar 501 to move up through the connecting rod 502. The end of the slide bar 501 slides up along the vertical groove 108, and on the other hand, drives the push plate 401 to move up, thereby ejecting the formed automobile interior panel from the inside of the concave mold cavity 101. After the automobile interior panel is ejected from the inside of the concave mold cavity 101, the slide bar 501 slides from the upper end of the vertical groove 108 into the inside of the inclined groove 107 and then continues to slide up along the inside of the inclined groove 107. At this time, the slide bar 501 can drive the push rod 403 to slide along the inside of the slide groove 103, and the sleeve 503 and the telescopic rod 504 are relatively extended. When the push rod 403 slides, it drives the push plate 401 to move horizontally. 1 drives the automobile interior panel above it to move horizontally, and then brings the formed automobile interior panel to the side of the male module 202 and the female mold cavity 101 for unloading operation; after the unloading of the current automobile interior panel is completed, the first driving component 30 drives the male mold base 201 and the male mold base 202 to move downward, the male mold base 201 drives the lifting rod 501 to move downward, the lifting rod 501 drives the push rod 403 to move downward through the sleeve 503 and the telescopic rod 504, the push rod 403 drives the slide rod 501 to slide downward along the inside of the inclined groove 107, and the slide rod 501 pulls the push rod 403 The push rod 403 slides in the opposite direction along the inside of the slide groove 103, and the push plate 401 moves in the opposite direction when the push rod 403 slides in the opposite direction, until the end of the slide rod 501 slides from the bottom of the inclined groove 107 to the inside of the vertical groove 108, and the push plate 401 moves in the opposite direction to the upper area of ​​the female mold cavity 101. As the lifting rod 501 continues to move downward, the end of the slide rod 501 slides down along the inside of the vertical groove 108, and the push rod 403 drives the push plate 401 to move downward and then re-embed into the storage groove 102, and then the male module 202 enters the female mold cavity 101 to complete the mold closing again.

[0041] See also Figure 1 , Figure 2 as well as Figure 3 In one embodiment, the push plate 401 is hingedly connected to the push rod 403, and the side wall of the push rod 403 is also connected to the bottom wall of the push plate 401 through a first elastic member 404. The first elastic member 404 is used to provide elastic support for the push plate 401 so that the push plate 401 remains horizontal at the upper end of the push rod 403. An extension rod 402 is also fixedly provided at the bottom of the push plate 401, and a limiting rod 106 is fixedly provided at the upper part of the bottom box 10 at the side of the die cavity 101.

[0042] After the push rod 403 drives the push plate 401 to move upward to eject the automobile interior panel from the inside of the female mold cavity 101, as the punch seat 201 and the lifting rod 505 continue to move upward, the end of the slide bar 501 slides from the upper end of the vertical groove 108 into the inclined groove 107 and then continues to slide upward along the inclined groove 107. At this time, the slide bar 501 drives the push rod 403 to slide along the inside of the slide groove 103, thereby driving the push plate 401 and the automobile interior panel located on the upper part of the push plate 401 to move horizontally. When one end of the push plate 401 moves out of the upper area of ​​the female mold cavity 101, the extension rod 402 at the bottom of the push plate 401 can act on the limit rod 106, and the limit rod 106 pushes the extension rod 402 to make the push plate 401 rotate to an inclined state compared with the push rod 403. At this time, the automobile interior panel located on the upper part of the push plate 401 can slide off by itself, thereby realizing automatic demoulding and unloading of the automobile interior panel; After demoulding and unloading are completed, as the punch seat 201, the convex module 202 and the lifting rod 505 move downward again, the lifting rod 501 drives the push rod 403 to move downward through the sleeve 503 and the telescopic rod 504, and the end of the slide rod 501 slides down along the inside of the inclined groove 107, and then pulls the push rod 403 while the push rod 403 moves downward to make the push rod 403 slide in the opposite direction along the inside of the slide groove 103, and the push rod 403 drives the push plate 401 to move horizontally in the opposite direction.

[0044] When the male module 202 is in a mold closing state inside the female mold cavity 101, the first ring block 507 acts on the upper end of the sliding sleeve 508 and keeps the sliding sleeve 508 in a downward pressure state. At this time, the push plate 401 is embedded in the storage groove 102. When the molten automobile interior trim panel raw material is injected into the female mold cavity 101 and solidified, as the male mold base 201, the male module 202 and the lifting rod 505 move upward, the sliding sleeve 508 slides down compared to the lifting rod 505, until the male module 202 moves out of the female mold cavity 101 and is pulled away from the pushing plate 401 by a certain distance. Then, the second ring block 509 acts on the bottom of the sliding sleeve 508 to push the sliding sleeve 508 so that the sleeve 503, the telescopic rod 504, the sliding rod 501, the pushing rod 403 and the pushing plate 401 move upward synchronously. After 401 ejects the automobile interior panel from the inside of the concave mold cavity 101, the slide rod 501 drives the push rod 403 to slide along the inside of the slide groove 103 under the action of the inclined groove 107, thereby driving the push plate 401 and the automobile interior panel above the push plate 401 to move horizontally. When the extension rod 402 at the bottom of the push plate 401 acts on the limit rod 106, since the push plate 401 and the convex module 202 above it are pulled apart by a certain distance at this time, the limit rod 106 can smoothly push the push plate 401 through the extension rod 402 so that the push plate 401 rotates to an inclined state compared to the push rod 403, and the convex module 202 will not interfere with the rotation of the push plate 401 and the automobile interior panel above it, thereby ensuring that the automobile interior panel can smoothly slide off from the top of the push plate 401 by itself.
