[0025] Example

[0026] like Figure 1-4 As shown, the polyurethane integrated molding die for automotive interiors proposed in the present invention includes a fixed bottom mold 1 and a movable top mold 2. The fixed bottom mold 1 is fixedly connected to a receiving trough 8 for receiving the molded interior parts on a side away from the sliding support rod 6. The die also includes a lifting mechanism installed directly above the movable top mold 2 to drive the movable top mold 2 up and down. A molding cavity 11 for molding the interior parts is defined within the fixed bottom mold 1. The inner bottom wall of the molding cavity 11 is slidably connected to a demolding mechanism for pushing the molded interior parts out of the molding cavity 11. A pair of sliding support rods 6 are fixedly connected to the outer wall of the fixed bottom mold 1. The ends of the pair of sliding support rods 6 away from the fixed bottom mold 1 are fixedly connected to a limit block 61 to prevent the limit slider 74 from being dislodged. When the limit slider 74 abuts the limit block 61, the end of the trapezoidal block 7 away from the limit block 61 cannot be pressed by the movable top mold 2. The sliding support rods 6 are slidably connected to a pushing mechanism that pushes the molded interior parts out of the demolding mechanism without hindering the closing of the movable top mold 2 and the fixed bottom mold 1.

[0027] Furthermore, the pushing mechanism includes a trapezoidal stopper 7, the end of the trapezoidal stopper 7 close to the fixed bottom mold 1 being fixedly connected to a pair of push plates 73, the bottom of the trapezoidal stopper 7 being fixedly connected to a limit slider 74 slidably connected to the sliding support rod 6, the lower surface of the movable top mold 2 being fixedly connected to the forming block 21, and the upper surface of the end of the trapezoidal stopper 7 away from the limit slider 74 being provided with an inclined stopper surface 75 which is moved away from the fixed bottom mold 1 after being pressed by the forming block 21, the inclined stopper surface 75 being provided with a rolling groove 71, the internal rotation of which is connected to a plurality of linearly arranged rollers 72. The function of the rollers 72 is to reduce the friction between the inclined stopper surface 75 and the forming block 21 when the forming block 21 presses against the inclined stopper surface 75, thereby making the trapezoidal stopper 7 slide more smoothly along the sliding support rod 6. The sliding support rod 6 is provided with a return spring 62, which is used to automatically move the trapezoidal stopper 7 that is not pressed toward the receiving trough 8. One end of the return spring 62 is fixedly connected to the limiting slider 74 , and the other end of the return spring 62 is fixedly connected to the outer wall of the fixed bottom mold 1 .

[0028] The demolding mechanism includes a telescopic slot 9 formed in the inner bottom wall of the fixed bottom mold 1. A push spring 91 is fixedly connected to the inner bottom wall of the telescopic slot 9. The push spring 91 is used to automatically eject the demolding push block 92 upward from the molding cavity 11 toward the molded interior component after it is no longer resisted by the molding block 21. The top end of the push spring 91 is fixedly connected to the demolding push block 92, which is slidably connected to the telescopic slot 9.

[0029] Furthermore, the lifting mechanism includes a plurality of supporting slides 5 fixedly connected to the upper surface of the fixed bottom mold 1, the top end of the supporting slides 5 is fixedly connected to the top plate 3, the upper surface of the top plate 3 is fixedly connected to the cylinder 4, and the piston rod of the cylinder 4 is movable through the top plate 3 and fixedly connected to the upper surface of the movable top mold 2.

[0030] In this embodiment, when it is necessary to use a polyurethane integrated molding die for automobile interior, such as Figure 1 As shown, by starting the cylinder 4 on the top plate 3, the piston rod of the cylinder 4 pushes the movable top mold 2 to slide along the support slide 5 in the direction of the fixed bottom mold 1. After the movable top mold 2 drives the forming block 21 on its lower surface to press against the inclined surface 75 on the trapezoidal block 7, the roller 72 provided in the rolling groove 71 causes the trapezoidal block 7 to drive a pair of push plates 73 to move toward the limiting block 61 through the limiting slider 74. Until the forming block 21 is inserted into the forming cavity 11 on the fixed bottom mold 1, the fixed bottom mold 1 and the movable top mold 2 can be integrally molded to produce the interior decoration parts. After the interior decoration parts in the fixed bottom mold 1 and the movable top mold 2 are formed, the cylinder 4 is started again to move the movable top mold 2 upward along the support slide 5. At this time, the elastic thrust of the push spring 91 in the telescopic groove 9 causes the push spring 91 to drive the demoulding push block 92 to push the interior decoration parts formed in the molding cavity 11 upward. As shown Figure 2 As shown, by the action of the trapezoidal stopper 7, the interior decoration part in the molding cavity 11 can be moved toward the receiving trough 8. And by the action of gravity, when the center of gravity of the interior decoration part is biased toward the receiving trough 8, the interior decoration part can slide into the receiving trough 8, which is simple and easy to operate.
