like Fig. 2 and shown in Figure 4, said drawing close to external mold through gear 11 drive tooth bars 9 promotion internal molds carried out pre-determined bit to internal mold; Be on tooth bar 9, to be provided with connecting key 10, on internal mold, be provided with keyhole, keyhole and connecting key 10 matched in clearance, connecting key 10 can produce gap 21, for reserving surplus in last accurate location between the keyhole on connecting key 10 rear ends and the internal mold when promoting internal mold; Simultaneously on the core 17 of internal mold, also be provided with lead-in chamfered, so that sealing strip inserts in the gap on external mold and two limits of internal mold smoothly.
said middle mould 5 through 2 pairs of external molds of patrix carries out final accurate location with backform 6 and internal mold; Be taper bolt 12 to be set, on middle mould 5 and backform 6, conical bore 14 be set, accurately locate with backform 6 through taper bolt 12 and conical bore 14 centering moulds 5 in the bottom surface of patrix 2; As shown in Figure 3, in the bottom surface of patrix 2 pyramid lock dog 13 is set, inclined-plane breach 15 is set on the internal mold, accurately locate through pyramid lock dog 13 and 15 pairs of internal molds of inclined-plane breach; Behind the location, gap 21 can be produced between the keyhole on connecting key 10 front ends and the internal mold, internal mold spreading backward can be prevented when injecting glue.
are as shown in Figure 5, said internal mold by mould in interior 16 be hinged in the core 17 of mould 16 both sides combine, core 17 is that fulcrum can upwards overturn with the pin joint after the die sinking, the convenient sealing strip that processes is broken away from from mould takes out.
according to the corner coupling head mould of a kind of sealing strip of the constructed the utility model of said method are: this mould comprises the counterdie 1 that is installed on the moulding press workbench and is installed in the patrix 2 on the moulding press top shoe; Patrix 2 tops are provided with hole for injecting glue 3; Counterdie 1 is provided with external mold and internal mold; External mold comprises the bed die 4 that stacks gradually connection, middle mould 5 and backform 6; Bed die 4 is provided with ball stud 7, and middle mould 5 is provided with locating hole 8 with backform 6; Ball stud 7 external diameters on the bed die 4 are less than the internal diameter of locating hole 8 on middle mould 5 and the backform 6.Internal mold is provided with keyhole, and the connecting key 10 on keyhole and the tooth bar 9 flexibly connects, and keyhole is a rectangular opening, and connecting key 10 is a square key; The length of keyhole is greater than the length of connecting key 10.Gear 11 on tooth bar 9 and the counterdie 1 is in transmission connection; Patrix 2 bottom surfaces are provided with taper bolt 12 and pyramid lock dog 13; In mould 5 and backform 6 be provided with the conical bore 14 corresponding with taper bolt 12; Internal mold is provided with and pyramid lock dog 13 corresponding inclined-plane breach 15.Mould 16 and core 17 in said internal mold comprises, core 17 and the hinged (see figure 5) in interior middle mould 16 both sides; Mould 16 is provided with keyhole in interior, and the chute on interior middle mould 16 and the counterdie 1 is slidingly connected, 10 flexible connections of the connecting key on the tooth bar 9 in keyhole and chute simultaneously.Said counterdie 1 is provided with spacer pin 19, and spacer pin 19 is arranged in the edge of mould 16 both sides counterdies 1.
The specific operation process of the utility model such as Fig. 2 are extremely shown in Figure 5,
Sketch map when
Fig. 2 is the dress mould starts molding press, and patrix is risen, and middle mould 5 is successively placed on the bed die 4 with backform 6, and during placement, locating hole 8 is through on the ball stud 7 on the bed die 4 and carries out pre-determined bit on middle mould 5 and the backform 6.Turning handle 18 then, promote internal mold through gear, tooth bar and draw close to external mold, then two straight sealing strips inserted mould from the gap location between internal mold and the external mold.
Fig. 3 is the sketch map behind the matched moulds; During matched moulds; The top shoe of molding press drives patrix 2 and moves down simultaneously, and after matched moulds put in place, the inclined-plane breach that the pyramid lock dog 13 on the patrix 2 heads on the internal mold pressed to external mold; Simultaneously the taper bolt 12 on the patrix 2 also closely is connected with conical bore 14 on the backform 6 with middle mould 5, makes all modules all be in final accurate position.
Pour into a mould then
, does not draw.Glue is injected in the die cavity that is surrounded by counterdie 1, patrix 2, external mold and core 17 from the hole for injecting glue at patrix top 3, and treating that glue and sealing strip are bonding fully carries out die sinking after firm.
sketch map when Fig. 4 is die sinking; During die sinking, the top shoe of molding press drives patrix 2 and moves up simultaneously, because backform 6 is the gap pre-determined bit with middle mould 5 with bed die 4; Again because the keyhole of interior middle mould 16 and the connecting key 10 on the tooth bar 9 are the gap flexible connection; So under the elastic force effect of sealing strip 20, backform 6, middle mould 5 and core 17 outwards open automatically, separate with sealing strip 20.
sketch map when Fig. 5 is the demoulding is pulled handle 18 swing pinions 11 then, makes internal mold away from external mold, the core on the internal mold 17 is upwards overturn take off the sealing strip of bonding one-tenth corner configurations, accomplishes an operation cycle process.
