Description
Technical field
The utility model relates to technology of die manufacturing field, particularly relates to a kind of assembled mould that can shorten the process-cycle.
Background technology
Mould is used to the instrument of formed article, is generally made up of dynamic model and cover half two parts, and dynamic model and cover half are combined and can form die cavity, by obtaining toward injected plastic in die cavity or metal stock the model wanted.The injection mold of a standard, generally includes upper clamping plate, cope match-plate pattern, material scraping plate, lower bolster, rest pad, counterdie seat board etc., and running gate system is also comparatively complicated in addition, is made up of sprue, runner and cast gate etc.There is following shortcoming in such mould: mould parts many at present, and the process-cycle is long; Cast gate adopts side to enter to water, and outward appearance is had to the part of requirement, gate vestiges cannot be avoided all the time.Comparatively simple for some overall structures, but higher part is required to part outer surface, traditional mould just cannot meet its requirement, and cost is higher, needs to study simple, the economic and practical mould of a kind of structure.
Utility model content
Many for overcoming existing mold part, the process-cycle is long, the high deficiency of use cost, and technical problem to be solved in the utility model is: provide a kind of economic and practical, shorten the assembled mould of process-cycle.
The utility model solves the technical scheme that its technical problem adopts: assembled mould, comprise cope match-plate pattern, lower bolster and sprue bush, cope match-plate pattern and lower bolster are assembled together by guide pillar, guide pillar is fixed on counterdie, patrix slides along guide pillar, and described cope match-plate pattern is provided with through hole, and described lower bolster is provided with type groove, described sprue bush is connected with the type groove of lower bolster through the through hole of cope match-plate pattern, matches with the type groove of lower bolster and form the die cavity of mould in the lower end of described sprue bush.
Further, the sidewall of described sprue bush lower end is provided with groove, and described groove is positioned at the type groove of lower bolster.
Further, the runner in described sprue bush is conical, and runner internal diameter reduces from sprue bush top gradually toward bottom.
Further, be provided with gum outlet bottom described sprue bush, the internal diameter of described gum outlet is less than the minimum diameter of runner.
The beneficial effects of the utility model are: cope match-plate pattern, lower bolster and sprue bush are grouped together and form the die cavity of mould, simplify mould structure, shorten the process-cycle; Cast gate is positioned at inside parts, without gate vestiges in appearance, improves surface forming quality; Sprue is directly connected with die cavity, and runner shortens, and the less use doses of running gate system, has saved molding time.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model close-up schematic view.
Be labeled as in figure, 1-cope match-plate pattern, 2-lower bolster, 3-sprue bush, 4-guide pillar, 5-part, 11-through hole, 21-type groove, 31-runner, 32-groove, 33-gum outlet.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the utility model mainly comprises three parts, cope match-plate pattern 1, lower bolster 2 and sprue bush 3, cope match-plate pattern 1 and lower bolster 2 are assembled together by guide pillar 4, guide pillar 4 is fixed on lower bolster 2, cope match-plate pattern 1 can move up and down along the direction of guide pillar 4, described cope match-plate pattern 1 is provided with through hole 11, described lower bolster 2 is provided with type groove 21, described sprue bush 3 is connected with the type groove 21 of lower bolster 2 through the through hole 11 of cope match-plate pattern 1, matches with the type groove 21 of lower bolster 2 and form the die cavity of mould in the lower end of described sprue bush 3.The die cavity of traditional moulds is all generally only be combined by cope match-plate pattern and lower bolster and formed, then on die cavity side, runner is set for injecting blank, adopt the mould general structure of this patten's design more complicated, and cast gate is positioned at part outside, gate vestiges can be left at part outer surface, affect surface forming quality.Improvements of the present utility model are sprue bush 3 to combine with the type groove 21 of lower bolster 2 cleverly, sprue bush 3 is made to become the part forming die cavity, thus simplify the structure of cope match-plate pattern 1 and lower bolster 2, also eliminate runner design simultaneously, directly just can toward injecting glue in die cavity by the runner 31 in sprue bush 3, and it is inner that cast gate is positioned at part 5, and appearance is without gate vestiges, and surface forming quality is good.
Traditional moulds is generally also provided with ejector apparatus, for being ejected from die cavity by shaping part.The utility model eliminates ejector apparatus, and conveniently take out part 5, the sidewall of described sprue bush 3 lower end is provided with groove 32, and as shown in Figure 2, described groove 32 is positioned at the type groove 21 of lower bolster 2.Because groove 32 is in type groove 21, when being stuck in the lower end of sprue bush 3 after part 5 coagulation forming under the effect of groove 32, only cope match-plate pattern 1 upwards need be lifted when taking out part 5, sprue bush 3 can move up together along with cope match-plate pattern 1 thus be taken out of from the type groove 21 of lower bolster 2 by part 5, convenient and swift, it is as far as possible tiny that groove 32 can do, be convenient to take off part 5, can exert oneself when taking off part 5 to stir part 5 downwards fast, the burr that part 5 is produced at groove 32 place is disallowable under the shearing force of groove 32 sidewall, ensure the Forming Quality of part 5.
Runner 31 in described sprue bush 3 is conical, and runner 31 internal diameter reduces from sprue bush 3 top gradually toward bottom, is provided with gum outlet 33 bottom sprue bush 3, and the internal diameter of described gum outlet 33 is less than the minimum diameter of runner 31.Cone cavity 31 and tiny gum outlet 33 are conducive to controlling into glue amount and entering glue speed, reduce gate vestiges.
The utility model structure is simple, and the process-cycle is short, and cast gate is positioned at inside parts, without gate vestiges in appearance, surface forming quality is high, and running gate system is made up of sprue and cast gate, and runner shortens, the less use doses of running gate system, saved molding time, production efficiency is high.
