A kind of mfg. moulding die of light leakage LED heart yearn, comprise mold affixed on the discharge end of bed die and bed die, described bed die is provided with feed cavity, the bottom surface of feed cavity described in this and mold are formed with through hole corresponding to position respectively, shape is respectively arranged with in the through hole of bed die and mold, the first block that position is corresponding and the second block, the through hole hole wall of described first block and bed die has interval apart and forms first flow, the through hole hole wall of described second block and mold has interval apart and forms the second runner, first block is also provided with third gear block with first flow described in partial occlusion, between described mold and bed die, described third gear block side is provided with the 3rd runner being communicated in described second runner, input coloured plastics material from described feed cavity and input colourless plastics thus the lamp strap core wire of one-shot forming light leakage from described 3rd runner.
As the improvement of technique scheme, the first block in described first flow and third gear block are combined into " ten " font, and the second block in described second runner is in " T " font.
As the further improvement of technique scheme, the outer wall of described mold and bed die is equipped with shell, described bed die outer wall is provided with the annular channel being communicated in described 3rd runner, described bed die outer wall is provided with the charging aperture being communicated in described annular channel, described shell is provided with the charging hole corresponding with described gating location.
Further, described outer casing inner wall is provided with identical tapering with the outer wall of mold, bed die, and the direction of tapering is consistent with the flow direction of plastics.
Further, described mold is arranged on described bed die by screw.
Further, described mold is provided with countersunk head screw hole.
Further, the upper surface of described bed die is provided with alignment pin, and described mold bottom surface is provided with the dowel hole with described alignment pin adaptation.
The beneficial effects of the utility model are: again pass second runner through after first flow with the colourless plastic composition inputted from the 3rd runner from the coloured plastics material of feed cavity input, owing to being provided with third gear block than the second runner in first flow more, therefore the breach of third gear block is filled up from the colourless plastics of the 3rd runner input, thus the lamp strap core wire of one-shot forming light leakage, the shape changing third gear block can produce the front of LED lamp bead and/or transmitting light from side surface and the lighttight lamp strap core wire in other faces, meet the decoration demand that user is different, improve the utilization ratio that LED lamp bead emits beam, improve decorative effect.The lamp strap core wire of the utility model one-shot forming light leakage, production process is few, and production efficiency is high, and cost is low.
