Description
Technical Field
[0001] This utility model belongs to the field of automotive trim strip production technology, and in particular relates to a molding die for automotive trim strip production. Background Technology
[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. They are often referred to as the "mother of industry." Car trim strips are decorative protective strips installed on the outside of the car's grille. The trim strips are injection molded using molds, and molding dies are often required when producing car trim strips.
[0003] Utility model patent publication number CN218366221U discloses a molding die for producing automotive trim strips, relating to the field of automotive mold technology. The die includes a first mold and a second mold. The first mold has a heat dissipation mechanism inside, and the second mold has a demolding mechanism inside. The demolding mechanism includes a mounting shaft, a threaded sleeve, a second movable part, a connecting column, and a first movable part. In the technical solution provided by this utility model, by setting up the demolding mechanism, after the trim strip cools, rotating the mounting shaft by rotating the adjusting component causes the second movable part inside the second mold to move to both sides, supporting and fixing the trim strip inside the slot. The trim strip supported by the second mold and the second movable part can be removed by lifting the second mold with a handle. Then, by pressing down on the pressure plate, the slot on the side wall of the connecting column disengages from the locking block. The connecting column drives the first movable part to move downwards, pressing down the trim strip on the side wall of the second mold, making demolding of the trim strip more convenient and increasing the production efficiency of the trim strip.

The two guide rods 12 on the left and two on the right are fixedly connected by connecting pieces 13, which are mounted on the top of the guide rods 12. A trim strip injection mold 6 is mounted on the bottom of the mounting plate 5. The top of the operating table 1 is also equipped with a trim strip injection mold. A trim strip lower injection mold 7 is used in conjunction with a trim strip. The inner cavity of the trim strip lower injection mold 7 is provided with an injection port. Both the trim strip upper injection mold 6 and the trim strip lower injection mold 7 have injection cavities in their inner cavities. An ejector plate 8 is slidably connected to the bottom of the injection cavity in the trim strip lower injection mold 7. An internal threaded cylinder 20 is fixedly connected to the right side of the bottom of the ejector plate 8. A threaded rod 19 is rotatably connected to the right end of the inner cavity of the operating table 1. The upper end of the threaded rod 19 is threadedly connected to the inner cavity of the internal threaded cylinder 20. A telescopic rod 23 is fixedly installed on the left side of the bottom of the ejector plate 8. The bottom of the telescopic rod 23 is fixedly installed on the left end of the inner cavity of the operating table 1. A gear 18 is fixedly connected to the bottom of the surface of the threaded rod 19. A rack 17 is slidably connected to the front side of the inner cavity of the operating platform 1. The rack 17 meshes with a gear 18. A sliding plate 16 is fixedly connected to the top of the rack 17. A guide rail 15 that works with the sliding plate 16 is installed at the bottom of the inner cavity of the operating platform 1. The sliding plate 16 slides on the top of the guide rail 15. A steel wire rope 14 is fixedly connected to the right side of the bottom of the mounting plate 5. The side of the steel wire rope 14 away from the mounting plate 5 is fixedly connected to the sliding plate 16. Through the cooperation of the steel wire rope 14, the sliding plate 16, the rack 17, the gear 18, the threaded rod 19, and the internal threaded cylinder 20, the mounting plate 5 and the ejector plate 8 are linked. When the mounting plate 5 rises, it will drive the ejector plate 8 to rise, thereby lifting the car... The decorative strip is ejected, and a push plate 9 is slidably connected to the top of the operating table 1. A bottom cylinder 11 is installed on the rear side of the top of the operating table 1. The output shaft of the bottom cylinder 11 is fixedly connected to the push plate 9. A storage box 10 that works with the push plate 9 is installed on the front side of the operating table 1.

[0024] Working principle: When using this utility model, the user drives the mounting plate 5 and the upper injection mold 6 of the trim strip to slide downwards via the top cylinder 4. At this time, the top plate 3 will slide on the surface of the guide rod 12, thereby causing the upper injection mold 6 of the trim strip to fit against the top of the lower injection mold 7 of the trim strip. Injection is performed into the inner cavity of the upper injection mold 6 and the lower injection mold 7 of the trim strip through the injection port in the lower injection mold 7. After cooling, the mounting plate 5 slides upwards, thereby causing the upper injection mold 6 and the lower injection mold 7 of the trim strip to separate. At the same time, the steel wire rope 14 is pulled to drive the sliding plate 16 to slide in opposite directions on the surface of the guide rail 15. At this time, the elastic telescopic rod 21 will retract, thereby driving the rack 17 to... The inner cavity of the operating table 1 slides, which in turn drives the gear 18 and the threaded rod 19 to rotate. Through the extension and retraction of the telescopic rod 23, the inner threaded cylinder 20 and the ejector plate 8 slide upward, thereby ejecting the injection-molded car trim strip from the inner cavity of the lower injection mold 7. Then, the bottom cylinder 11 drives the push plate 9 to slide towards the inner cavity of the storage box 10. The push plate 9 pushes the car trim strip into the inner cavity of the storage box 10, thereby realizing automatic material unloading, reducing manual operation, and improving the injection molding efficiency of the car trim strip. When the mounting plate 5 slides down during the next injection, the elastic telescopic rod 21 uses its rebound force to drive the sliding plate 16 to reset, thereby driving the ejector plate 8 to reset.
[0025] In summary, the molding die for producing automotive trim strips uses an ejector plate 8 to slide upwards and eject the injection-molded automotive trim strip from the inner cavity of the lower injection mold 7. Then, the pusher plate 9 pushes the automotive trim strip into the inner cavity of the storage box 10, thereby achieving automatic material unloading, reducing manual operation, and thus improving the injection molding efficiency of automotive trim strips.
