Description
Technical field
The utility model relates to a kind of being specifically designed to and has long line article, as the improvement of the vertical injection mold of plug of usefulness such as plug cord.
Background technology
Vertical die, because the restriction of its folding modular space, its volume is all smaller, is suitable for injecting small sized product.The article that have long line, as the electric power connecting line, owing to need the plug portion volume of injection moulding little, so generally all finish with vertical injection mold.The existing vertical die that is used for the injection moulding patch, as shown in Figure 7, it comprises dynamic model 100, cover half 200 and mould bar 300 (also claiming the mould handle), described cover half 200 comprises solid plate 210 (being the B plate), below described solid plate 210, be provided with ejector pin mechanism 220, on the upper bottom surface of solid plate 210, be provided with following wire casing 240, die 250 and be used to place the counterdie bar groove 260 of mould bar 300 down successively, below described ejector pin mechanism 220, be provided with lower shoe 230; Described dynamic model 100 comprises moving platen 110 (being the A plate), on the bottom surface of described moving platen 110, position with respect to following wire casing 240, following die 250 and counterdie bar groove 260 is respectively arranged with wire casing 120, upper cores 130 and patrix bar groove 140, is provided with upper plate 150 on described moving platen 110; Locate by guide pillar 160 and guide pin bushing 270 between described dynamic model 100 and the cover half.During use, the mould bar 300 that naked plug connecting line will be housed earlier is placed in the counterdie bar groove 260, allow the lead correspondence of connecting line be placed on down in the wire casing 240, dynamic model 100 moves down, the mould 120 of reaching the standard grade constitutes complete line mould with following wire casing 240 matched moulds, hold lead, upper cores 130 constitutes die cavity with following die 250 matched moulds; The runner 400 of existing this vertical injection mold as shown in Figure 8, it comprises sprue 410, runner 420, branch flow passage 430 and discharging opening 440, half sets sprue 410 template 210 and (sees Fig. 7 near on the upper bottom surfaces of counterdie bar groove 260 1 sides, down together), half of runner 420 is located on the upper bottom surface of mould bar 300, and half of branch flow passage 430 is provided with by on the inwall of die cavity one side along the mould bar, discharging opening 440 1 ends communicate with branch flow passage 430, and the other end communicates with die cavity; Cope match-plate pattern 110 corresponding to sprue 410, runner 420, branch flow passage 430 and discharging opening 440 corresponding be provided with sprue 410, runner 420, branch flow passage 430 and discharging opening 440 second half, behind dynamic model 100 and cover half 200 matched moulds, constitute complete sprue 410, runner 420, branch flow passage 430 and discharging opening 440.During injection moulding, the plastics of thawing enter from the injection orifice 460 of injection molding plates 450, flow into mold cavity forming.After injection moulding is finished, die sinking and extract mould bar 300 after, at this moment the shape of its product, has the waste material 600 identical with runner 400 shapes as shown in Figure 9 on product 500.This waste material 600 or melt again as inferior material uses, or sells as waste product.The existence of so most amount waste materials, the yield rate of the unit's of greatly reducing raw material has also increased manufacturing cost simultaneously; Sale also has pollution to environment as waste product.How to reduce the waste material that vertical injection molding machine produces in injection moulding process as far as possible, for a long time, industry difficult problem always.Though, on horizontal injection mold, adopt hot flow path, can well reduce the generation of waste material,, because the restriction of vertical injection mold volume, be used for hot flow path scheme on the horizontal injection mold and be not suitable for and be directly used in vertical injection mold.
