Description
Technical field
The present invention relates to a kind of injection mould.
Background technology
Injection mould is mainly used in the shaping of thermoplastic articles, and the forming principle of injection mould is: by screw rod or the piston of injector, makes the plastic warp nozzle of plastifying fusion in barrel and running gate system inject die cavity, and goods needed for curing molding.The primary structure of injection mould comprises fixing die and movable punch, in the side of die, sprue body is set, the die cavity that runner and die and the punch of sprue body are formed communicates, for the ease of discharging, ejector beam is provided with in punch side, but existing injection mould often adopts single ejector beam to eject goods, for the goods that some lateral dimensions are larger, adopt single ejector beam, its discontinuity, when being ejected from punch, its medial surface or lateral surface easily and other structures produce to wipe and hang and form scratch, affect the presentation quality of goods.
Summary of the invention
The invention is intended to provide a kind of injection mould that goods steadily go out part of guaranteeing, not affect the presentation quality after product molding.
A kind of injection mould in this programme, comprise the fixed clamping plate vertically arranged, the side of fixed clamping plate is fixed with die, punch is relative with die position, and punch can side-to-side movement and die matched moulds time form die cavity, punch is fixed on dynamic model backing plate, sprue body is provided with in the side of die, the sprue of sprue body communicates with die cavity, dynamic model backing plate vertically evenly offers multiple horizontally-guided hole side by side, sprue puller is equipped with in pilot hole, sprue puller can side-to-side movement, one end of sprue puller can extend in die cavity, the other end of sprue puller is fixed on a liftout plate, the guide pin bushing plate of a ring-type is fixed with in the side direction of dynamic model backing plate, liftout plate can slide along the inwall of guide pin bushing plate.
The advantage of this programme is: in the pilot hole of dynamic model backing plate, worn multiple uniform sprue puller, when therefore going out part after product molding, liftout plate drives multiple sprue puller to move right, the rod end acting in conjunction of each sprue puller is on goods, goods are ejected from punch, and when liftout plate moves, the effect of guiding is played in the motion of guide pin bushing plate to liftout plate, makes motion more steady.
Further, sprue is the tapered hole that increases gradually of radius from outside to inside.Sprue makes the form of tapered hole, and the plastics being conducive to melting flow in die cavity rapidly and uniformly.
Further, be provided with the solid plate of ring-type in the periphery of die, solid plate is provided with the through hole of level, and the periphery of punch is provided with the moving platen of ring-type, and moving platen is provided with the guide pillar of level, and when punch and die matched moulds, guide pillar can be inserted in through hole.When punch and die matched moulds, the effect of guiding is played in the motion of guide pillar to punch.
Further, sprue body is threaded with fixed clamping plate, and fixed clamping plate is provided with locating ring, and the inner ring of locating ring and the cylindrical of sprue body offset.Locating ring plays the effect of location to sprue body.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: locating ring 1, sprue body 2, fixed clamping plate 3, solid plate 4, moving platen 5, dynamic model backing plate 6, guide pin bushing plate 7, liftout plate 8, eject base plate 9, sprue puller 10, push rod 11, guide pillar 12, punch 13, die 14, cooling-water duct 15.
Embodiment is substantially as shown in Figure 1: the injection mould of the present embodiment, fixed clamping plate is vertically arranged, and the side of fixed clamping plate is fixed with die, is provided with the solid plate of ring-type in the periphery of die, and solid plate is provided with the through hole of level.Be provided with sprue body in the side of die, sprue body is threaded with fixed clamping plate, and the sprue of sprue body communicates with die cavity, and sprue is the tapered hole that increases gradually of radius from outside to inside.Fixed clamping plate is provided with locating ring, and the inner ring of locating ring and the cylindrical of sprue body offset.
Punch is relative with die position, and punch can side-to-side movement and die matched moulds time form die cavity.Punch is fixed on dynamic model backing plate.The periphery of punch is provided with the moving platen of ring-type, and moving platen is provided with the guide pillar of level, and when punch and die matched moulds, guide pillar can be inserted in through hole, and moving platen is also fixed on dynamic model backing plate.Dynamic model backing plate vertically evenly offers five horizontally-guided holes side by side, sprue puller is equipped with in pilot hole, sprue puller can side-to-side movement, one end of sprue puller can extend in die cavity, the other end of sprue puller is fixed on liftout plate, the side of liftout plate is fixed with one and ejects base plate, is fixed with the guide pin bushing plate of a ring-type in the side direction of dynamic model backing plate, and liftout plate can slide along the inwall of guide pin bushing plate.
In the present embodiment, punch and die are equipped with cooling-water duct, and fixed clamping plate and solid plate are connected by screw, guide pin bushing plate, dynamic model backing plate and moving platen are all connected by screw.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
