Below according to a kind of working process and principle of hot runner plastic injection mould of the above example description present invention.
Cover half component 100 and dynamic model component 200 mold, and plastic melt enters hot runner flow distribution plate by sprue bush 112
121, melt uniformly enters the annular channel 222 on cover half core 131 from 6 hot nozzles 140, then by being connected to annular channel 222
Forming cavity 240 is entered with 8 cow glue powders 223 of forming cavity 240, melt uniformly flows into ox horn along annular channel 222 and pours
Mouth 223 carries out uniform filler in forming cavity 240, can fill up very narrow forming cavity 240, good forming effect avoids
Many defects, pressurize cool down formed product, and injection molding machine mandril first pushes ejector retainner plate 270, ejector retainner plate 270 to move band during die sinking
Dynamic ejector retainner plate fixed plate 260, jacking block mandril 231 and slanted kicking block 230 move, and jacking block mandril 231 drives slanted kicking block 230 to move together
By product and condensate demoulding ejection, demoulding when, since 223 discharge port of cow glue powder is comparatively fine, demoulding when product with
Condensate at cow glue powder 223 breaks disengaging, and condensate deviates from mold by condensate mandril 225 and condensate push rod 224.
When molding, ejector retainner plate guide pillar spring 272, which restores, drives ejector retainner plate 270 and ejector retainner plate fixed plate 260 to reset, ejector retainner plate
270 and ejector retainner plate fixed plate 260 drive jacking block mandril 231 and angle ejector rod 290 accurately multiple under the auxiliary of moving-mould-core locating piece 221
Position, is molded by locking force of injection machine, completes entire molding cycle.
The present invention carries out the charging of plastic melt by 6 nozzles and 8 cow glue powders 223 so that melt being capable of average price
It is filled into very narrow forming cavity 240, injecting products can reach design requirement, under the auxiliary of slanted kicking block 230 outside product
Side is along groove has been molded, and jacking block mandril 231 drives slanted kicking block 230 to remove during demoulding, and groove can be demoulded smoothly, production
The buckle structure on product inner side edge edge is molded by 290 upper end of angle ejector rod.Angle ejector rod 290 is inclined along direction is limited when demoulding
It moves, buckle structure can be demoulded smoothly.
Ramp-roof structure comes each tiny position of shaped article side, and simple in structure to be convenient in demoulding, mold developing cycle is short,
Cost is relatively low；Using 6 nozzles 8 into mode of pouring come injected plastic melt, good appearance after formed product can reach design and want
It asks；Hot runner mould can improve raw material availability.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
