Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-7 As shown, an embodiment of this application provides an injection mold for an LED footlight housing, which includes a fixed mold mechanism 1, a demolding mechanism 2, and a moving mold mechanism 3. The fixed mold mechanism 1 includes a first fixed plate 11, a panel 12, and a fixed mold 13. Two fixed mold cores 14 are symmetrically arranged on the fixed mold 13. A pouring mechanism 15 for pouring into the molding cavity is provided through the first fixed plate 11, the panel 12, the fixed mold 13, and the fixed mold cores 14. Each of the two fixed mold cores 14 is provided with a first contouring part and several first contouring pillars 142 for shaping the openings of the housing. The demolding mechanism 2 includes two symmetrically arranged demolding components 21. The moving mold mechanism 3 includes a second fixed plate 31, an ejection mechanism 32, and a moving mold 33. Two moving mold cores 34 are symmetrically arranged on the moving mold 33. Each of the two moving mold cores 34 is provided with a second contouring part 341 and several second contouring pillars 342.

[0029] The demolding assembly 21 includes two symmetrically arranged sliders 211, which slide in cooperation with the moving mold 33. One end of the slider 211 is provided with a contour block 212, and the slider 211 is provided with a positioning hole 213 at an incline. The fixed mold 13 is provided with a positioning post 131 at an incline for positioning and sliding cooperation with the positioning hole 213. The positioning post 131 is used to extend into the positioning hole 213 to drive the slider 211 to move horizontally. The first contour part, a plurality of first contour posts 142, the second contour part 341, a plurality of second contour posts 342 and the two contour blocks 212 close to form a molding cavity for injection molding the shell.

[0030] A first cooling component 214 for cooling the molding cavity is disposed through the slider 211.

[0031] Specifically, when injection molding of the housing is required, the drive mechanism drives the fixed mold mechanism 1 to move towards the moving mold mechanism 3 and the demolding mechanism 2. Four inclined positioning pins 131 on the fixed mold 13 of the fixed mold mechanism 1 extend into the four positioning holes 213 of the four sliders 211 of the two demolding components 21. This causes the two sliders 211 of the demolding components 21 to move relative to the contour blocks 212. The first contour part of the fixed mold core 14, the plurality of first contour pins 142 of the fixed mold core 14, the second contour part 341 of the moving mold core 34, the plurality of second contour pins 342 of the moving mold core 34, and the two contour blocks 212 of the sliders 211 close to form a molding cavity for injection molding of the housing, thus forming two molding cavities for injection molding. Then, the hot-melt plastic material flows into the two molding cavities through the gating mechanism 15 to perform injection molding of the four housings. The first cooling component 214 on the slider 211 cools the molding cavity, accelerating the molding speed of the housing. After the shells in the two molding cavities are injection molded, when the drive mechanism drives the fixed mold mechanism 1 to disengage from the moving mold mechanism 3, the positioning pin 131 on the fixed mold 13 moves, thereby driving the slider 211 to move outward to demold the shells in the molding cavity. Then, the ejection mechanism 32 ejects the four shells on the two moving mold cores 34. Finally, the unloading mechanism unloads the four shells.

[0032] In the above structure, the demolding efficiency of the injection-molded shell is improved by setting the demolding component 21. Furthermore, the cooling efficiency of the shell is greatly improved by setting the first cooling component 214 on the demolding component 21, thus increasing the molding speed of the shell. The demolding efficiency of the demolding component 21 is further improved by the cooperation of the inclined positioning pin 131 and the positioning hole 213, while also saving operating costs. This injection mold not only realizes the injection molding operation of the LED footlight shell but also improves injection molding efficiency and saves production time.

[0033] like Figures 4-6As shown, in one embodiment, the first cooling assembly 214 of the LED footlight housing injection mold includes a first water inlet pipe 001, a first cooling water pipe 002 penetrating within the slider 211, and a first water outlet pipe 003. The two ends of the first cooling water pipe 002 are connected to the first water inlet pipe 001 and the first water outlet pipe 003, respectively. The first water inlet pipe 001 is connected to an external water inlet device, and cooling water flows from the first water inlet pipe 001 into the first cooling water pipe 002. The first cooling water pipe 002, in a U-shape, penetrates within the slider 211, cooling the slider 211 and the molding cavity. Finally, the cooling water flows out from the first water outlet pipe 003. This arrangement improves the cooling efficiency of the molding cavity and accelerates the molding speed of the housing within the molding cavity.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, one end of the first fixing plate 11, fixed mold 13, moving mold 33, and ejection mechanism 32 of the LED footlight housing injection mold is provided with a mold foot assembly 4 for providing space for external devices of the first cooling assembly 214. The mold foot assembly 4 includes two symmetrically arranged mold feet 41. This arrangement facilitates the provision of installation space for external water inlet devices of the first cooling assembly 214, eliminating the need for frequent disassembly of the external water inlet devices.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the injection mechanism 15 of the LED footlight housing injection mold includes a glue inlet pipe 151 and two symmetrically arranged glue flow pipes 152. The glue inlet pipe 151 is mounted on the panel 12 and the first fixed plate 11, and communicates with the two glue flow pipes 152. The two glue flow pipes 152 pass through the fixed mold 13 and the fixed mold core 14, respectively, and communicate with the two molding cavities. When the fixed mold mechanism 1 and the moving mold mechanism 3 are closed, the hot-melt plastic material flows from the glue inlet pipe 151 into the two glue flow pipes 152, and then from the two glue flow pipes 152 into the two molding cavities. This arrangement facilitates the injection molding operation of the housing by allowing the hot-melt plastic material to flow into the two molding cavities.

[0036] like Figure 2 As shown, in one embodiment, the panel 12 of the LED footlight housing injection mold is provided with a heating component 121 for heating the colloid in the casting mechanism 15. The heating component 121 includes a first inlet 004, a heating pipe 005 extending through the panel 12, and a first outlet 006. Heating liquid flows into the first inlet 004, into the heating pipe 005, and heats the glue inlet pipe 151 and the glue outlet pipe 152, finally flowing out from the first outlet 006. This arrangement increases the flow rate of the hot melt plastic material, thereby improving injection molding efficiency.

[0037] like Figure 3 and Figure 7 As shown, in one embodiment, two second cooling components 35 are symmetrically arranged on the fixed mold 13 and moving mold 33 of the LED footlight housing injection mold for cooling the fixed mold core 14 and moving mold core 34, respectively. Each second cooling component 35 includes several second inlets 007 and several second outlets 008, with a second cooling water pipe 009 positioned between the second inlets 007 and the second outlets 008. Coolant flows into the second inlets 007, passes through the second cooling water pipes 009 penetrating the fixed mold 13 and fixed mold core 14, or through the second cooling water pipes 009 penetrating the moving mold 33 and moving mold core 34, cooling the two molding cavities. Finally, the cooling water flows out from the second outlets 008. This arrangement improves the cooling efficiency of the two molding cavities and accelerates the injection molding speed of the four housings.

[0038] like Figure 7 As shown, in one embodiment, the ejection mechanism 32 of the LED footlight housing injection mold includes a first ejector plate 321, a second ejector plate 322, and two vertically symmetrically arranged positioning plates 323. The first ejector plate 321 and the second ejector plate 322 are slidably engaged with the two positioning plates 323. Two contour ejector assemblies 324 passing through the moving mold 33 and the moving mold core 34 are symmetrically arranged on the first ejector plate 321. A support column assembly 311 is arranged on the second fixing plate 31. The support column assembly 311 passes through the second ejector plate 322 and the first ejector plate 321 to support the moving mold 33. A guide column assembly 325 is arranged between the first ejector plate 321 and the moving mold 33. A spring 326 is arranged on the guide column assembly 325. One end of the spring 326 abuts against the ejector plate, and the other end of the spring 326 abuts against the moving mold 33. After the four housings in the two molding cavities are injection molded, the drive mechanism drives the second ejector plate 322 to move the first ejector plate 321 and two contour ejector assemblies 324 to eject the four housings on the two moving mold cores 34. After the ejection is completed, the drive mechanism drives the second ejector plate 322 back to its initial position, and the first ejector plate 321 returns to its initial position under the force of the spring 326. This arrangement improves the ejection efficiency of the four housings.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
