[0022] Example:

[0023] like Figures 1 to 3 As shown, a forming machine for a rigid polyurethane sandwich panel comprises: a base 1, a forming groove 11 is provided at the top of the base 1 near the back, a plurality of groups of hydraulic cylinders 12 with output ends facing the top are equidistantly arranged near the left and right sides of the bottom of the forming groove 11 from front to back, a bottom plate 13 is provided at the output end of the hydraulic cylinder 12, a built-in groove 14 is provided inside the base 1 and on the front of the forming groove 11, a driving gear 15 is symmetrically arranged inside the built-in groove 14 near the left and right sides, a motor 16 with output ends facing the bottom is symmetrically arranged on the left and right sides of the top of the base 1 near the front, a slide groove 17 is symmetrically provided at the top of the base 1 near the left and right sides, a screw rod 18 is provided inside the slide groove 17, a driven gear 19 is provided inside the screw rod 18 extending to the built-in groove 14, a slider 110 is sleeved on the periphery of the screw rod 18, and a push plate 111 is provided at the top of the base 1 where the slider 110 extends.

[0024] like Figures 1 to 3As shown, the hydraulic cylinder 12 is fixedly connected to the forming groove 11, and the bottom plate 13 is fixedly connected to the output end of the hydraulic cylinder 12. The extension of the hydraulic cylinder 12 can drive the bottom plate 13 to move up and down, so that the hard polyurethane sandwich panel is pushed out of the forming groove 11 to achieve the purpose of taking the panel. A support block 141 is provided inside the built-in groove 14 and at the bottom of the driving gear 15. The support block 141 is fixedly connected to the built-in groove 14, and the driving gear 15 is rotatably connected to the support block 141. The driving gear 15 can be supported by the support block 141, and it can also make its rotation smoother, thereby improving the stability of use. The motor 16 is fixed to the base 1 by bolts, and the output end of the motor 16 is fixedly connected to the driving gear 15. The rotation of the motor 16 can drive the driving gear 15 to rotate, thereby driving the push plate 111 to move forward and backward, completing the unloading work and improving the processing efficiency. The screw rod 18 rotates with the base 1 The driven gear 19 is fixedly connected with the screw rod 18, and the driven gear 19 is meshed with the driving gear 15. The rotation of the driving gear 15 can drive the screw rod 18 to rotate through the driven gear 19, thereby completing the unloading work. The slider 110 is adapted to the screw rod 18, and the slider 110 is slidably connected with the slide groove 17. The push plate 111 is fixedly connected with the slider 110. The rotation of the screw rod 18 can drive the slider 110 to perform a linear reciprocating motion. The slider 110 can be limited by the slide groove 17 to prevent it from spirally rotating with the screw rod 18, thereby improving the stability of use. An inspection door 142 is provided at the top of the base 1, close to the front and located at the top of the built-in groove 14. The inspection door 142 is rotatably connected to the base 1 through a rotating shaft. The inspection door 142 is rotatably connected to the base 1, so that it can be easily opened, thereby performing inspection and maintenance on the interior of the built-in groove 14, thereby improving the convenience of use.

[0025] In summary, when a rigid polyurethane sandwich panel molding machine is used to mold a rigid polyurethane sandwich panel, the mixed panel-making material is first injected into the molding groove 11 through an external device, and the panel-making material in the molding groove 11 is hot-pressed and molded by an external hot-pressing device. After the rigid polyurethane sandwich panel is hot-pressed and molded, the external hot-pressing device is removed from the molding groove 11, and the bottom plate 13 is extended upward by the hydraulic cylinder 12, so that the bottom plate 13 drives the rigid polyurethane sandwich panel to move upward, thereby completing the panel removal work, replacing the traditional manual panel removal. The cumbersome process effectively improves the processing efficiency. The motor 16 drives the driving gear 15 to rotate, so that the driving gear 15 drives the screw 18 to rotate through the driven gear 19. The slider 110 drives the push plate 111 to move in the direction of the hard polyurethane sandwich panel inside the slide groove 17 under the action of the screw 18, and drives the hard polyurethane sandwich panel to move toward the back of the base 1 until the hard polyurethane sandwich panel is pushed to the top of the external conveying equipment. The whole work process is completed, avoiding manual contact with the high-temperature hard polyurethane sandwich panel, and effectively reducing safety hazards.
