Description

Technical Field

[0001] This utility model relates to the field of lamp housing die casting mold technology, specifically a die casting mold for producing metal lamp housings. Background Technology

[0002] In existing LED lighting fixtures, the outer casing is mostly made of metal to improve heat dissipation. Furthermore, because LED lights generate high temperatures, manufacturers incorporate fin-like heat dissipation structures into the casing to reduce heat, making the external structure of the metal casing complex. Currently, the die-casting process for metal lamp housings generally uses a traditional fixed mold structure, requiring demolding after the die-casting is complete.

[0003] Existing lamp housing die-casting equipment often relies on manual demolding after the complex metal casing of existing lamp housings. However, manual demolding is relatively inefficient in actual production, affecting both production efficiency and safety. Furthermore, due to the intricate and complex nature of lamp housing die-casting, misalignment during mold closing can lead to defects. The anti-misalignment protection capability is insufficient, resulting in suboptimal production quality. Therefore, we propose a die-casting mold for producing metal lamp housings to address these issues. Utility Model Content

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.

[0027] Please see Figures 1 to 5 A die-casting mold for producing metal lamp housings includes a die-casting production table 1, with a support frame 2 on the top of the die-casting production table 1.

[0028] The top of the support frame 2 is provided with a lifting die-casting cylinder 3. The output end of the lifting die-casting cylinder 3 passes through the inside of the support frame 2 and is fixedly connected to a lifting mounting plate 4. The bottom of the lifting mounting plate 4 is bolted to a top die-casting mold 5. The center of the top of the die-casting production table 1 is bolted to a bottom pressure mold 6. The edge of the lifting mounting plate 4 is slidably connected to the rod of the support frame 2.

[0029] The bottom pressure mold 6 has auxiliary mold openings 7 on both sides of the top. The auxiliary mold openings 7 are equipped with a movable spring 8 and a compression push plate 9. The compression push plate 9 is fixedly installed on the top of the movable spring 8. The top of the compression push plate 9 is higher than the top of the bottom pressure mold 6.

[0030] The beneficial effects of this solution are as follows: A support frame 2 is provided on the top of the die-casting production table 1. The support frame 2 can support and carry the lifting die-casting cylinder 3. A lifting mounting plate 4 is fixedly installed at the bottom of the lifting die-casting cylinder 3. Running the lifting die-casting cylinder 3 can drive the lifting mounting plate 4 to rise and fall, thereby driving the top die-casting mold 5 at the bottom of the lifting mounting plate 4 to approach the bottom pressure mold 6, thereby completing the die-casting of the metal lamp shell. The edge of the lifting mounting plate 4 is engaged and slidable on the support frame 2, so that the top die-casting mold 5 is not easy to deviate when rising and falling, resulting in high die-casting accuracy and high die-casting quality.

[0031] The bottom pressure mold 6 has auxiliary mold openings 7 on both sides of the top. The auxiliary mold openings 7 are equipped with movable springs 8 and extrusion push plates 9. After the die casting mold is closed, the top die casting mold 5 can extrude and push the extrusion push plates 9 into the interior of the auxiliary mold openings 7. After the die casting is completed, the extrusion push plates 9 can be pushed upward by the elastic force of the movable springs 8. The extrusion push plates 9 can extrude the metal lamp shell, achieving the demolding effect. This makes the device achieve automated die casting demolding with high demolding efficiency, no manual labor required, high safety, excellent anti-deviation ability, and excellent die casting quality.

[0032] Furthermore, the support frame 2 includes four support columns 21 and a support plate 22. The four support columns 21 are installed at the four corners of the top of the die-casting production table 1. The top of the four support columns 21 is fixedly connected to the bottom of the support plate 22. The lifting die-casting cylinder 3 is installed on the top of the support plate 22. The bottom of the lifting die-casting cylinder 3 passes through the support plate 22.

[0033] By setting the support frame 2, which includes four support columns 21 and one support plate 22, the four support columns 21 can stably support the support plate 22, so that the support plate 22 can stably support the lifting die-casting cylinder 3, resulting in stable overall operation and uniform force distribution.

[0034] Furthermore, the four corners of the lifting mounting plate 4 are slidably connected to the four support columns 21, and the top die-casting mold 5 is bolted and fixed to the bottom center of the lifting mounting plate 4.

[0035] By setting the four corners of the lifting mounting plate 4 to be slidably connected to the four support columns 21, the lifting mounting plate 4 can always remain horizontal and stable during lifting and lowering, and is not easy to deviate or tilt, thus achieving high die-casting precision and excellent practicality.

[0036] Furthermore, wear-resistant rings 10 are fixedly installed at the four corners of the lifting mounting plate 4, and the four wear-resistant rings 10 are slidably connected to the four support columns 21 respectively.

[0037] By setting the wear-resistant ring 10, the lifting mounting plate 4 can be raised and lowered, and the wear-resistant ring 10 can play a role in preventing slippage and wear resistance on the support column 21. It has good wear protection effect, stable operation and excellent durability.

[0038] Furthermore, there are no fewer than two lifting die-casting cylinders 3, which are hydraulic cylinders, and the two lifting die-casting cylinders 3 are evenly and symmetrically distributed on the top of the lifting mounting plate 4.

[0039] By setting at least two lifting die-casting cylinders 3, the operation is stable and the force is even. The lifting die-casting cylinders 3 are hydraulic cylinders, which have high operating strength and good die-casting effect. The lifting die-casting cylinders 3 are symmetrically distributed, so that the lifting die-casting cylinders 3 can stably push the lifting mounting plate 4 to move up and down and press it down stably.

[0040] Furthermore, the bottom of the movable spring 8 is fixedly connected to the bottom of the auxiliary mold opening 7. The vertical height of the auxiliary mold opening 7 is higher than that of the extrusion push plate 9. The top of the extrusion push plate 9 is provided with an anti-slip pad 11.

[0041] By setting a movable spring 8 between the auxiliary mold opening 7 and the extrusion push plate 9, it can elastically rise and fall according to the pressure changes of the extrusion push plate 9. The vertical height of the auxiliary mold opening 7 is higher than that of the extrusion push plate 9, so that the extrusion push plate 9 can be completely stored inside the auxiliary mold opening 7, ensuring stable die casting and convenient demolding. The anti-slip pad 11 plays an anti-slip role, making demolding convenient and practical.

[0042] Furthermore, the extrusion push-off plate 9 is slidably connected to the inner side of the auxiliary mold opening 7. The extrusion push-off plate 9 is inverted convex shape, and the top of the auxiliary mold opening 7 is in contact with the top of the extrusion push-off plate 9.

[0043] By setting the extrusion push plate 9 to be inverted convex shape, it can stably fit the inner side of the auxiliary mold opening 7 when pressed. When subjected to force, the extrusion push plate 9 can squeeze the metal lamp shell to complete the demolding. The structure is simple and demolding is convenient.

[0044] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use.

[0045] Working principle: A support frame 2 is provided on the top of the die-casting production table 1. The support frame 2 can support and carry the lifting die-casting cylinder 3. A lifting mounting plate 4 is fixedly installed at the bottom of the lifting die-casting cylinder 3. Running the lifting die-casting cylinder 3 can drive the lifting mounting plate 4 to rise and fall, thereby driving the top die-casting mold 5 at the bottom of the lifting mounting plate 4 to approach the bottom pressure mold 6, thereby completing the die-casting of the metal lamp shell. The edge of the lifting mounting plate 4 is engaged and slidable on the support frame 2, so that the top die-casting mold 5 is not easy to deviate when rising and falling, resulting in high die-casting accuracy and high die-casting quality.

[0046] Auxiliary mold openings 7 are provided on both sides of the top of the bottom pressure mold 6. A movable spring 8 and a pressing push plate 9 are installed in the auxiliary mold opening 7. The pressing push plate 9 is slidably engaged in the auxiliary mold opening 7. When the top die-casting mold 5 and the bottom pressure mold 6 are closed, the top die-casting mold 5 can press and push the pressing push plate 9 into the interior of the auxiliary mold opening 7. After die-casting is completed, the pressing push plate 9 can be pushed upward by the elastic force of the movable spring 8. During the upward displacement, the pressing push plate 9 can push out the metal lamp shell that is attached to the bottom pressure mold 6, achieving the demolding effect. This makes the device achieve automated die-casting demolding with high demolding efficiency, no manual labor required, high safety, excellent anti-deviation ability, and excellent die-casting quality.
