[0024] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 — Figure 7 As shown, this embodiment provides a molding die for automotive elastic polyester cotton material, including a frame 1, a conveyor 2, a mold device 3, an injection system 4, and a swing system 5. The conveyor 2 is mounted on the frame 1, and the swing system 5 slides along the frame 1. The conveyor 2 and the swing system 5 are connected by a transmission. The conveyor 2 drives the swing system 5 to move, allowing the swing system 5 to move closer to or further away from the injection system 4. The mold device 3 is mounted on the swing system 5. During the movement of the swing system 5, the swing system 5 drives the mold device 3 to swing, accelerating the material flow within the mold device 3, promoting the expulsion of air bubbles, and ensuring molding quality. The injection system 4 is mounted on the frame 1 and is located above the conveyor 2. The injection system 4 is adapted to the mold device 3 for injection.
[0025] The swing system 5 includes a swing frame trolley 51, a central suction device 52, and two side push devices 53. The side push devices 53 are installed on both sides of the swing frame trolley 51, which is slidably mounted on the frame 1. The sliding of the swing frame trolley 51 moves the mold device 3, thereby bringing the mold device 3 closer to the pouring system 4 for pouring, and after pouring, moving the mold device 3 away from the pouring system 4. The central suction device 52 is installed in the middle of the swing frame trolley 51. The bottom of the mold device 3 is provided with a V-groove 321. The mold device 3 is placed on the central suction device 52 through the V-groove 321, preventing the mold device 3 from falling off the swing frame trolley 51. The machine slides down, and the frame 1 is provided with several push-in inclined blocks 12. The side push device 53 is slidably installed on the swing frame trolley 51 in the lifting direction. The side push device 53 is connected to the mold device 3 in a transmission. The side push device 53 follows the trajectory of the swing frame trolley 51 as it moves and passes through each push-in inclined block 12. Then, while the swing frame trolley 51 slides along the frame 1, the side push device 53 slides on the push-in inclined block 12. Under the push of the inclined surface on the upper surface of the push-in inclined block 12, the machine moves up and down, so that the side push device 53 slides up and down along the swing frame trolley 51, thereby pushing the mold device 3 to swing, accelerating the material flow in the mold device 3, promoting the discharge of air bubbles, and ensuring the molding quality.
[0026] Specifically, the conveyor 2 includes a conveyor motor and a conveyor chain. The conveyor chain passes around each sprocket and is mounted on the frame 1 via several sprockets. Each sprocket is rotatably mounted on the frame 1. The conveyor motor is mounted on the frame 1 and is connected to the conveyor chain via a drive. The swing frame trolley 51 is mounted on the conveyor chain and is connected to the sprocket via a drive. The rotation of the conveyor motor pulls the conveyor chain to move, thereby realizing the movement of the swing system 5.
[0027] Specifically, the mold device 3 includes an upper module 31 and a lower module 32 that are assembled together. A V-groove 321 is located at the bottom of the lower module 32. The upper module 31 is adapted to the injection system 4. The injection system 4 injects material into the upper module 31. The material is injected into the cavity between the upper module 31 and the lower module 32 to realize the molding of polyester cotton material.
[0028] Specifically, the injection system 4 includes an injection gun 41 and an injection motion device 42. The injection gun 41 is mounted on the injection motion device 42, and the injection motion device 42 is mounted on the frame 1. The injection gun 41 is adapted to the mold device 3 to inject material.
[0029] Specifically, the swing frame trolley 51 includes a trolley slider 511, a swing frame body 512, and a fixing bolt 513. The frame 1 is provided with a mold sliding rail 11. The swing frame body 512 is mounted on the mold sliding rail 11 via the trolley slider 511 to realize the lateral movement of the swing frame body 512. The fixing bolt 513 is mounted on the trolley slider 511 and points towards the mold sliding rail 11. During material pouring, the fixing bolt 513 temporarily fixes the swing frame trolley 51 to ensure no material leakage. As a more automated design, the fixing bolt 513 can be replaced by a cylinder that pushes against the mold sliding rail 11 when it extends.
[0030] Specifically, the central attraction device 52 includes an attraction bar 521 and an attraction push spring 522. The attraction bar 521 is slidably mounted on the swing frame trolley 51. The two ends of the attraction push spring 522 respectively abut against the bottom of the attraction bar 521 and the top of the swing frame trolley 51. The top of the attraction bar 521 has a sharp corner that matches the V-groove 321, thereby maintaining the position of the mold device 3 and preventing the mold device 3 from being misaligned. The top of the attraction bar 521 has a permanent magnet to further prevent the mold device 3 from being misaligned. The V-groove 321 swings under the constraint of the top of the attraction bar 521, accelerating the movement of the mold device 3. The material flowability promotes the expulsion of air bubbles. The reason for setting the suction push spring 522 is that when the injection system 4 is injecting, when the injection system 4 presses down and aligns with the preset injection port on the upper module 31, the suction push spring 522 can be compressed, so that the lower module 32 is pressed down onto the two side push devices 53, thereby stabilizing the mold device 3 during injection. In order to ensure a stable connection between the injection system 4 and the preset injection port on the upper module 31, the injection system 4 is hemispherical near the injection port, thus ensuring a seal during the injection process when the upper module 31 swings with the V-groove 321.
[0031] Specifically, the side-pushing device 53 includes a push block 531, which is slidably mounted on the swing frame trolley 51. The push block 531 is connected to the push inclined block 12 for transmission, which drives the mold device 3 to swing to ensure molding quality.
[0032] The working method of the molding die for automotive elastic polyester cotton material includes the following steps: S1: Place the mold device 3 on the central suction device 52; S2: The mold device 3 moves closer to the injection system 4 under the drive of the swing system 5; S3: The injection system injects material into the mold device 3 to form the mold; S4: The oscillating system 5 drives the mold device 3 to oscillate, promoting material flow and ensuring molding effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
