With reference to the accompanying drawings, describe the present invention in detail by example.Among the figure:
Fig. 1 is the plane of injector of the present invention;
Fig. 2 is the side view of the injector of Fig. 1;
Fig. 3 is the side view that amplify the part of the injector of Fig. 1, expresses an adjusting device;
Fig. 4 is the section plan that is applicable to the mould of injector shown in Figure 1.
Fig. 1 to Fig. 3 represents an injector 10 of the present invention, and it comprises an elongated support 11, is installed in the die assembly 12 on the end of support 11, is installed in three injection member 13 (13A, 13B and 13C) on the support 11 relative ends.Die assembly 12 comprises a split type mould 14 and an air pressure driving mechanism 15, and this mechanism is used for making a module 14A in the composite die 14 to move toward or away from another with being fixed on module 14B on the support 11.Three injection member 13 are bearing on the shared carriage 16, carriage is slidably, and by an air pressure driving mechanism (not shown) driving, can slide along any direction longitudinally of support 11, therefore can be with three injection member 13 of moved further, make them toward or away from composite die 14, particularly Gu Ding module 14B.
Each injection member 13 all comprises a body 17 that is fixed on the carriage 16; A turbination funnel 18 that is contained on the bodies top by this funnel, can add the plastic bead that full injection molding is used to body 17 again; And also have a horizontal column casing 19, it extends forward from the top of body 17.Column casing 19 has an injection nozzle 20 foremost at it, and the coaxial adjustable screw spare (not shown) of an inside is housed, and can be used to melting shape plastics are passed through injection nozzle 20 from body 17 forward through column casing 19, is injected into composite die 14.
From Fig. 1, can know and find out, the part of three injection member 13 by its Part No. after additional A, B, C distinguish.Three injection member 13 and their column casing 19 extend ground along support 11 parallel longitudinals side by side and are provided with.Injection member 13B is arranged between two other injection member 13A and the 13C.Each side injection member 13A and 13C comprise adjusting device 21, are used for regulating the effective length from the column casing 19 of corresponding body 17 actual measurements.Column casing 19 is slidably mounted on the coaxial hollow shaft 29, and the rear end of axle 29 is fixed on the body 17.
Can clearly be seen that from Fig. 3 adjusting device 21 is by two carriages 22 and 23, and pass carriage 22 and 23 and the screw rod 24 of its engagement constitute.Carriage 22 is fixed on the outside of injection member body 17, and carriage 23 is fixed on the rear end of column casing 19.Screw rod 24 passes carriage 23 earlier, meshes and pass nut 25 and carriage 22 again.Fastening nut 25 is fixed on screw rod 24 on the carriage 23, makes the free end and carriage 22 engagements of screw rod 24, thus the relative position of decision column casing 19 on axle 29.
Use this structure, column casing 19A or 19C, and the position of their injection nozzle 20A or 20C is to regulate with respect to the injection nozzle 20B of injection member 13B placed in the middle.And injection member 13B placed in the middle is not provided with this adjusting device 21, the result, and the relative position of column casing 19B or its injection nozzle 20B can not be regulated.
Referring to Fig. 4, the internal structure of its expression composite die 14, this mould can be used to produce the pearl string of pearl-decorated curtain.This pearl-decorated curtain generally comprises the pearl string that dangles of row, every pearl string along on its length all the compartment of terrain be molded into discontinuous plastics pearl.These pearls can be designed to different shapes, to improve the vision appeal.The details of this pearl-decorated curtain disclosed in British patent gazette UK2210774.
In this embodiment, composite die 14 is designed to have three groups independently the internal flow path to flow through the plastics of fusing.Every group of path all has taper import 26A, 26B or 26C, and flow passage leads in one group of three die cavity 27 that have a same shape, and the shape of die cavity is that each group is different mutually.Because three groups of flow passages separate, thereby the plastics of different plastics and/or different colours can be injected in corresponding each group of die cavity 27, the pearl string that obtains multiple style and color is to improve the vision appeal.
In initial operation, the support 16 of injector 10 is driven by air pressure and moves forward, and fully closely meshes together up to the injection nozzle 20B of injection member 13B placed in the middle and the import 26B placed in the middle of composite die 14.Slightly the position of column casing 19A is adjusted forward by additional regulating device 21 subsequently, joggled strength engagement is fully closely arranged between the respective inlets 26A of injection nozzle 20A and composite die 14.Operation adjusting device 21 needs with two spanners, and a handle is used for the head of screw rod 24, and another is used for nutting 25.Nut 25 is unscrewed in beginning gently, then, unscrews simultaneously from screw head, subsequently screw rod 24 is extracted out from carriage 22 forward.Do like this, carriage 23 and column casing 19A are promoted forward with respect to bolster 29 by the nut on the screw rod 24 25.Between injection nozzle 20A and mould import 26A, enough engagement forces are arranged, nut 25 is tightened on the carriage 23, column casing 19A locking is put in place.Injection nozzle 20C and column casing 19C repetition said sequence ground to another injection-moulded component 13C are adjusted.
Engagement force between each injection nozzle 20 and the corresponding mould import 26 should reach fully big, to avoid injection molded material from any undesirable seepage between meshing part.
At this moment, just can begin molded.At first, promote module 14A with driving mechanism 15, module 14B ground extends through rope the die cavity 27 of composite die 14 with composite die 14 matched moulds to make it push against fixedly.Injection molded material with different colours is injected in the die cavity 27 of composite die 14 by injection nozzle 20 and import 26 respectively then, and to form three groups of pearl strings on rope, every group has specific color.Use driving mechanism 15 then, open composite die 14 with drawing back module 14A, so that take out the pearl string of making.So just finished a molding process, can repeatedly operate then so that obtain another pearl string.When molded EO, can from mould 14, extract injection member 13 out, perhaps be used for changing composite die 14, perhaps be used for cutting off injector 10 with different pearl processing die cavitys.Before reusing injector 10, general unnecessary injection nozzle relative position or effective column casing length of regulating injection member 13A and 13C again.
Obviously, repeatedly mesh between injection nozzle 20 and the composite die 14 and break away from will inevitably be because of wearing and tearing and tearing of making in injection nozzle 20 and the composite die 14 or the both damages or distortion normally.When this damage or distortion generation, adjusting device 21 is used for readjusting the relative position of injection nozzle, or effective column casing length of injection member 13A and 13C, thereby make three injection nozzle 20 aim at corresponding mould import 26, therefore can avoid seepage at injection nozzle engagement place moulding material.
Before injection nozzle is aimed at, preferably unscrew the nut 25 of two adjusting devices 21 earlier, can at first fully closely mesh with the injection nozzle 20B that guarantees injection member 13B placed in the middle with mould import 26B.Perhaps, also can injection column casing 19A and 19C be moved backward, be in the most forward position so that injection nozzle 20B placed in the middle compares with 20C with its side injection nozzle 20A with adjusting device.Thereafter, by using adjusting device 21 can make the injection nozzle of side injection member 13A and 13C and composite die engagement place reach no any seepage.
Adjusting device 21 can also be used to injection nozzle 20 is aimed at the not injection molding on same plane of a kind of all mould imports.
Can expect that adjusting device of the present invention also can not be arranged on the above-mentioned position, for example can be located between injection column casing and its injection nozzle.Injector also can have 2,4 or more injection member.
Below described the present invention by way of example, in the scope of claims of the present invention, those skilled in the art can make various changes or modification.
