During current injection moulding was produced, most precise injection molding moulds all used TOP-TIP, to save resin raw material, obtained good injection molding technology, made product quality, production capacity all be improved simultaneously.Use TOP-TIP, reduced the length of runner, injection pressure is reduced, alleviated the burden when mould is produced, thereby reduced the thermal degradation of resin simultaneously the service life of having improved mould, reduced the internal stress of goods.So TOP-TIP has become the trend of mould of plastics.
TOP-TIP is being widely used in the process of all kinds of moulds, die casting producer is brought into play advantage separately, or cooperates with hot flow path supplier, or oneself researches and develops, and uses standard component, has promoted the progress of Tool and Die Technology.This technology is exactly a kind of new theory that TOP-TIP is used for bicolor injection mould.
The bicolor injection mould that uses has two kinds basically at present: run-in index and angie type.In the angie type bicolor injection mould, TOP-TIP is using.Injection moulding for the first time uses hot flow path a lot, but the majority of injection moulding (side is advanced glue) is for the second time still using cold runner, uses cooling duct inevitably to have the waste and the intrinsic disadvantage of cold runner mould of resin raw material.The supplier of some TOP-TIP makes the flow distribution plate form with side running channel and main running channel, as shown in Figure 1.But this structure has certain limitation, and price general charged is all very high, makes the cost of mould also along with increase.And it is not quick detachable, maintenance, maintenance inconvenience.
With three plate angie type bicolor injection moulds is example, and side runner has increased runner and coagulated the length of expecting, has promptly increased waste material.Because runner is long, need very big pressure during injection moulding simultaneously.The mould pressurized is big, and is also big to the impact of runner, can be easy to produce flash on the die joint of runner peel plate and cavity plate, thereby influence Shooting Technique.
For two plate angie type bicolor injection moulds, there is similar problem equally.Though the most TOP-TIPs that adopt of the main running channel of injection moulding for the first time, still there is great waste in the side running channel.
Summary of the invention
Defective and deficiency in view of above-mentioned prior art exists the purpose of this invention is to provide a kind of angie type bicolor injection mould that has hot mouth formula TOP-TIP.It is TOP-TIP with hot mouth formula that this mould adopts side to advance the mode of watering.Owing to designed hot mouth formula TOP-TIP, thereby solved the flash that is easy to generate of cold runner side running channel structure existence, the problem of resin raw material waste etc., and solved the board-like side running channel of existing shunting TOP-TIP and cost an arm and a leg, the problem of maintenance, maintenance inconvenience.Not only guarantee product quality and production capacity, and reduced die cost.
The technical scheme that the present invention is taked to achieve these goals is: a kind of angie type bicolor injection mould that has hot mouth Shi Redao system, comprise runner peel plate, cavity plate and TOP-TIP, it is characterized in that: described TOP-TIP comprises sprue bush, hot mouth and positioning sleeve, described hot mouth is fixed on the described runner peel plate by sprue bush and positioning sleeve, is provided with in the side of described cavity plate simultaneously to be used for guaranteeing that described TOP-TIP does not produce the locating piece of play under the injection moulding high pressure.
The beneficial effect that the present invention produced is: reduced the generation of waste material, guaranteed product quality and production capacity, reduced die cost, can be widely used in the injection moulding production.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Embodiment one: with three plate angie type bicolor injection moulds is example, and three plate angie type bicolor injection mould primary structures have three blocks of plates, i.e. runner peel plate, cavity plate and cover half version are because the structure of solid plate is identical with the cover half of prior art, so do not provide in Fig. 2.
Referring to Fig. 2, the present invention includes runner peel plate 4, cavity plate 5 and TOP-TIP, TOP-TIP comprises sprue bush 1, hot mouth 2 and positioning sleeve 3, hot mouth 2 is fixed on the runner peel plate 4 by sprue bush 1 and positioning sleeve 3, is provided with in the side of cavity plate 5 simultaneously to be used for guaranteeing that TOP-TIP does not produce the locating piece 7 of play under the injection moulding high pressure.
The mating surface 31,32 that the inner chamber of positioning sleeve 3 is respectively equipped with and hot mouth is fixing and and the outer wall of hot mouth 2 between leave the empty avoiding face 33 in gap, the mating surface 34 that the outer wall of positioning sleeve 3 is respectively equipped with and runner peel plate 4 is fixing and and runner peel plate 4 between leave the empty avoiding face 35 in gap.The pairing cavity plate of hot mouth 2 nozzle end 5 positions be provided be convenient to take off material draw material nail 6.
Above scheme is that Jiang Rezui (hot sprue) adds the side running channel.TOP-TIP is fixed on the runner peel plate, and it is fastening in side and die sinking direction screw to be set respectively, and locating piece is set on cavity plate simultaneously, and this location, several places can guarantee that the TOP-TIP position is determined under the injection moulding high pressure, does not produce play.
Hot mouth formula TOP-TIP primary structure is shown in Fig. 3,4.By positioning sleeve 3 and sprue bush 1 hot mouth 2 is fixed.Mating surface 31,32 by positioning sleeve 3 among Fig. 7 cooperates with hot mouth 2, to hot mouth 2 location.Empty avoiding face 33 makes and has the gap between positioning sleeve 3 and the hot mouth 2, by contacting of the isolated iron of air and iron, hot mouth 2 had insulation effect, and heat energy is fully used.Simultaneously positioning sleeve 3 and runner peel plate 4 are satisfiedly cooperating, are leaving empty avoiding face 35 under the fastening prerequisite in Fig. 4, heat-insulation and heat-preservation once more, effective use of energy sources.Cooperating between mating surface 34 and the runner peel plate 4 should be according to the character appropriate design of resin material, anti-leak-stopping material.Select the side running channel of hot flow path for use, make its running channel keep molten condition, reduced this section waste material, improved product quality.Because the mold filling resistance is little, reduce injection pressure in addition, also shortened molding cycle, helped the raising of cost savings and production efficiency.The hot mouth of a lot of brands has been arranged on the market, can rationally select for use according to actual conditions.
