Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an aluminum mold assembly for an integrated LED floodlight. Background Technology

[0002] LED integrated floodlights, as essential equipment in modern urban and industrial lighting, typically use aluminum alloy for their housings to meet requirements for heat dissipation, lightweight design, and aesthetics. With the rapid development of LED lighting technology, the market has placed higher demands on the dimensional accuracy, surface quality, and production efficiency of floodlight housings. Traditional aluminum housing manufacturing processes mainly include die casting, extrusion, and machining. Among these, injection molding has been widely used in LED floodlight housing production due to its advantages such as high molding efficiency and good dimensional stability.

[0003] During the demolding process of existing LED floodlight aluminum molds, the large contact area between the mold sidewall and the formed aluminum part can easily cause scratches or deformation on the surface of the aluminum part, affecting product yield and appearance quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] An aluminum mold assembly for an integrated LED floodlight includes a base 1 with vertical supports 2 fixedly mounted on both sides of its top. A horizontal top plate 3 is fixedly connected to the top of the two supports 2. A mold closing mechanism is located below the center of the top plate 3. The mold closing mechanism includes an upper mold 8, which is movably mounted directly below the bottom of the top plate 3. A vertical hydraulic cylinder 9 is fixedly mounted at the center of the top of the top of the top plate 3. A hanger 10 is fixedly connected to the output shaft of the hydraulic cylinder 9. The bottom sides of the hanger 10 are fixedly connected to the top sides of the upper mold 8. An injection port 11 is provided in the center of the upper mold 8. Vertical pressure strips 20 are fixedly connected to the bottom sides of the upper mold 8. A rack 21, corresponding to a gear 12, is fixedly connected to the upper end of the opposing side of each pressure strip 20. Rectangular grooves 22, aligned with the pressure strips 20 and coaxial with the pressure strips 20, are provided on both sides of the base 1. When the pressure strips 20 penetrate the rectangular grooves 22, the racks 21 and gear 12... The base 1 is fixedly connected to the top center of the lower mold 4. The lower mold 4 has an injection groove 5 in the middle. Vertical L-shaped sliding side molds 6 are movably installed on both sides of the injection groove 5. A translation mechanism is provided between the lower mold 4 and the L-shaped sliding side molds 6. The translation mechanism includes a gear 12. The gear 12 is rotatably installed on the middle of the outer wall of both sides of the lower mold 4 via a rotating shaft. The gear 13 meshes with the gear 12 on the middle of the inner wall of both sides of the lower mold 4 via a rotating shaft. Eccentric wheels 14 are symmetrically arranged on both sides of the gear 13. The eccentric wheels 14 are movably connected to the outer end face of the L-shaped sliding side mold 6. The translation mechanism also includes a fixed seat 15. Vertical fixed seats 15 are fixedly connected to the top of both sides of the lower mold 4. A spring 16 is elastically connected between the fixed seat 15 and the upper outer end of the L-shaped sliding side mold 6. The upper end face of the fixed seat 15 and the upper end face of the L-shaped sliding side mold 6 are at the same horizontal line.

[0026] In this embodiment, by setting a translation mechanism that links the L-shaped sliding side mold 6 with the eccentric wheel 14, the L-shaped sliding side mold 6 can quickly detach from the side wall of the aluminum profile 23 during mold separation, significantly reducing the contact area during the demolding process. This avoids the surface scratches and deformation problems common in traditional mold demolding, and greatly improves product yield and appearance quality.

[0027] like Figure 2 and Figure 4 As shown, a connector 7 is movably installed directly below the bottom of the base 1. A demolding mechanism is provided between the base 1 and the connector 7. The demolding mechanism includes ejector pins 17. Several ejector pins 17 are regularly arranged in the middle of the top of the connector 7. Mounting seats 18 are fixedly connected to both sides of the middle of the top of the connector 7 and both sides of the middle of the bottom of the base 1. The upper and lower mounting seats 18 are elastically connected by springs 19. The mold closing mechanism cooperates with the translation mechanism and the demolding mechanism.

[0028] In this embodiment, the demolding mechanism composed of ejector pin 17 and spring 2 19, in conjunction with the linkage control of the mold closing mechanism, automatically completes the ejection action during mold separation, achieving rapid demolding without manual intervention, significantly improving production efficiency, and is especially suitable for mass production needs.

[0029] Working principle: During mold closing, hydraulic cylinder 9 drives hanger 10 to move upper mold 8 downward. Pressure strips 20 on both sides of upper mold 8 simultaneously pass through rectangular grooves 22 of base 1. The rack 21 on pressure strip 20 meshes with gear 12 to drive it to rotate. Gear 12 drives gear 23, which meshes with it, to rotate. Eccentric wheels 14 on both sides of gear 23 rotate accordingly and push L-shaped sliding side molds 6 to move towards each other, so that the two L-shaped sliding side molds 6 together with upper mold 8 and lower mold 4 form a closed molding space. At this time, molten aluminum is injected into injection port 11. At the same time, upper mold 8 presses down to move connecting piece 7 down and compress spring 2 19. Ejector pin 17 descends to avoid the molding space; during mold separation, hydraulic cylinder 9 lifts upper mold 8, and as pressure bar 20 moves upward, rack 21 drives gear 12 to rotate in the opposite direction, which in turn drives eccentric wheel 14 to rotate through gear 23. L-shaped sliding side mold 6 moves away from the side wall of aluminum profile 23 under the tension of spring 16. At the same time, spring 29 releases its elasticity to push connector 7 upward. Ejector pin 17 pushes the molded aluminum profile 23 out of injection groove 5 of lower mold 4 to complete demolding. During this process, the retraction action of L-shaped sliding side mold 6 effectively reduces the contact area with aluminum profile 23 and avoids scratching the product surface during demolding.

[0030] It should be noted that the ejector pins 17 are arranged in a 4×4 rectangular array.
