Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] According to one embodiment of the present invention, in conjunction with the appendix Figures 1-5 As shown.

[0024] A high-yield injection mold for automotive center console front trim panels includes a top mold 1 and a bottom mold 2. Two demolding mechanisms 5 are fixedly mounted on the outer surface of the bottom mold 2. An electric push rod 3 14 is fixedly connected to the bottom surface of the bottom mold 2. A square top plate 16 is fixedly connected to the output end of the electric push rod 3 14. A groove 15 matching the size of the square top plate 16 is formed inside the bottom mold 2. The demolding mechanism 5 includes a support frame 51 fixedly connected to the outer surface of the bottom mold 2. An electric push rod 1 52 is fixedly connected to the inner wall of the support frame 51. The output end of electric push rod 1 52 is fixedly connected to a secondary bracket 53. The inner wall of the secondary bracket 53 is fixedly connected to electric push rod 2 54. The output end of electric push rod 2 54 is fixedly connected to a side push plate 55. The demolding mechanism 5, electric push rod 3 14 and square top plate 16 form a multi-directional demolding system. Driven by the electric push rods, the system achieves coordinated demolding of the front trim panel of the car center console from the side and bottom, effectively solving the demolding problem of complex structure trim panels, improving the demolding success rate and product quality, reducing manual intervention and improving demolding efficiency.

[0025] In this embodiment, two recesses 13 are formed on the upper surface of the bottom mold 2. The recesses 13 are adapted to the side push plate 55. When the demolding mechanism 5 is working, the side push plate 55, driven by the electric push rod 54, extends into the bottom mold 2 along the direction of the recesses 13, contacts the front trim panel of the car center console and applies a pushing force, making the demolding process smoother. A support frame 3 is fixedly connected to the bottom surface of the bottom mold 2. The inner wall of the support frame 3 is fixedly connected to the bottom end of the electric push rod 14. The support frame 3 provides a stable support for the bottom mold 2. The support enhances the overall stability of the mold, ensuring its balance under injection pressure and demolding force, preventing mold shaking or tilting, and guaranteeing the safe and stable progress of the injection and demolding processes. A controller 4 is fixedly connected to the outer surface of the bottom mold 2. The controller 4 is electrically connected to electric push rod 1 52, electric push rod 2 54 and electric push rod 3 14 through wires, realizing centralized control and intelligent operation of the demolding process.

[0026] In this embodiment, the upper surface of the bottom mold 2 is provided with multiple venting grooves 9. These venting grooves 9 can promptly expel air and gas generated by the molten plastic inside the mold during injection molding, preventing defects such as bubbles and voids from forming inside the decorative panel. Their width, depth, and length are rationally designed according to the characteristics of the molten plastic and the injection molding process parameters. Their depth is generally controlled between 0.02-0.05 mm, effectively venting air from the cavity and preventing molten plastic from overflowing. The venting grooves 9 are connected to the external atmosphere, ensuring that air inside the cavity can be quickly expelled. The bottom surface of the top mold 1 is provided with multiple positioning ports 7. Positioning rods 6, which are compatible with the positioning ports 7, are fixedly connected to the upper surface of the bottom mold 2. The positioning ports 7 of the top mold 1 and the positioning rods 6 of the bottom mold 2 are compatible, playing a precise positioning role during mold closing, ensuring that the top mold 1... The bottom mold 2 is accurately aligned with the mold cavity to ensure that the shape and size of the mold cavity meet the design requirements and guarantee the molding accuracy of the front trim panel of the car center console. Two connecting slide pillars 10 are fixedly connected to the outer surface of the bottom mold 2. Each connecting slide pillar 10 has a sliding plate 11 slidably connected to its outer surface. Each sliding plate 11 has a connecting plate 12 fixedly connected to its upper surface. The top of each connecting plate 12 is fixedly connected to the outer surface of the sub-support 53. The sliding structure composed of the connecting slide pillars 10 and the sliding plate 11 provides guidance and support for the sub-support 53, enabling the sub-support 53 to move smoothly under the drive of the electric push rod 52. This ensures that the demolding mechanism 5 is stable and reliable during operation and avoids the demolding effect being affected by shaking or displacement. The outer surface of the top mold 1 is provided with an injection tube 8, which is used to inject molten plastic into the mold cavity and is a key component in the injection molding process.

[0027] Working principle: During mold installation, the support base 3 is fixed on the working platform, and the bottom mold 2 is installed on the support base 3. During the injection molding process, when the molten plastic is injected into the mold cavity, the air inside the mold and the gas generated by the molten material are discharged from the mold through the venting groove 9. As the molten material fills, the gas escapes from the venting groove 9, allowing the molten material to fully fill the mold cavity. After injection molding is completed, the electric push rod 3 14 is activated first. The electric push rod 3 14 extends, driving the square top plate 16 to rise from the groove 15 of the bottom mold 2, initially pushing the trim panel out from the bottom. Then, the electric push rod 2 54 and the side push plate 55 are activated to move into the mold, so that the side push plate 55 is located below the trim panel. Then, the electric push rod 1 52 is activated, and the electric push rod 1 52 pushes the sub-support 53 to move. When the sub-support 53 moves, it will move the side push plate 55 and push the front trim panel of the car center console to move, so that the trim panel is separated from the side wall of the mold, completing the demolding operation, improving the demolding success rate and product quality.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
