Description
Technical field
The present invention relates to a kind of shoe making apparatus, and in particular to a kind of cast polyurethane device for making sole.
Background technology
Sole is by pouring head（As cast polyurethane device）By cast polyurethane to footwear mould（As shown in Figure 5）Die cavity
Formed after interior foaming.At present during general pouring head work, its discharging opening is all in alignment with the bottom surface material feeding of footwear mould die cavity, i.e. polyurethane
Foamed since die cavity bottom surface, then slowly fill die cavity, as shown in Figure 4.However, there is problems with this material feeding mode：
First, because polyurethane foams since die cavity bottom surface, polyurethane is slowly covered on die cavity side, therefore lateral shortage is enough
Pressure so that die cavity side polyurethane between air be extruded, so shaping after, side of the sole has stingy one by one
Bubble, largely effects on aesthetics；Second, some soles are different side sole, therefore the die cavity of footwear mould is also special-shaped die cavity, due to abnormity
The side of die cavity has re-entrant angle, in material feeding, and polyurethane is difficult to completely fill out re-entrant angle, therefore after shaping, the side of sole is non-
Often unsightly.

Fig. 2 is the sectional view in Fig. 1 along A-A directions；
Fig. 3 is cast schematic diagram of the invention；
Fig. 4 is cast schematic diagram of the prior art；
Fig. 5 is the stereogram of footwear mould.
Embodiment
As shown in Figures 1 and 2, this three-dimensional cast polyurethane device includes main valve body 20 and stirring set 4, main valve body 20
It is the charging main body of mixed material, material is entered in stirring set 4 by main valve body 20, the stirring-head in agitated set 4（Do not draw
Go out）Stirring mixing, polyurethane just from discharging opening discharge, thus progress cast work.
Poured into a mould to realize since membrane cavity side, stirring of the invention covers 4 rotatable settings, and stirs set 4 and driving
The power source drive connection that stirring set 4 is rotated, the lower end of stirring set 4 is provided with the discharge nozzle 6 communicated with stirring set 4, the discharging
The discharging opening of pipe 6 is towards outside, and " outside " here refers to the direction in cast against footwear mould die cavity side.
As shown in figure 3, during work, three-dimensional cast polyurethane device is moved integrally along the length of die cavity（For prior art）,
Because the discharging opening of discharge nozzle 6 is towards outside, rather than down, therefore during the movement of discharge nozzle 6, discharging opening is poured against membrane cavity side
Note, because discharge nozzle 6 is directly material to be sprayed onto on membrane cavity side, therefore have enough power to make material be substantially adhered to membrane cavity side
On face, bubble that may be present is excluded, not accessible re-entrant angle, therefore either common die cavity, or special-shaped die cavity is filled, all
Mold sole not only attractive in appearance but also complete；When reaching die cavity end, power source drive stirring set 4 is rotated, and discharge nozzle 6 turns therewith
Dynamic, such discharge nozzle 6 is poured into a mould against the side of die cavity end, and with the movement and rotation of discharge nozzle 6, polyurethane fills
All sides of membrane cavity point are attached to, when covering one back and forth（Flow can also walk less it is multiple back and forth）, filling polyurethane is expired whole
Individual die cavity.By above-mentioned pouring type, the problem of prior art is present can be thoroughly solved, the attractive in appearance of sole is substantially improved
Degree.
As described above, the discharging opening of discharge nozzle 6 is bent outwardly towards outside, therefore the lower end of discharge nozzle 6, makes discharging opening
Against the side of die cavity；Certain discharge nozzle 6 can not also be bent, but tilted and installed, as long as by its discharging opening against die cavity
Side.But the discharge nozzle 6 of bending does not interfere with flow, manufacture is also more convenient with installing.
Discharge nozzle 6 can be arranged directly on 4 lower ends of stirring set, can also be integrally formed with stirring set 4, but clear for convenience
Wash, discharge nozzle 6 is arranged on discharge head 5 by the present invention, and the discharge head 5 is removably mounted on the lower end of stirring set 4, specifically
It is the lower end for being threaded in stirring set 4.When needing cleaning discharge nozzle 6, discharge head 5 is pulled down.
As shown in Fig. 2 the discharge head 5 has funnelform stream chamber 50, the top of discharge nozzle 6 is arranged on the stream of discharge head 5
Intracavitary.Funnelform stream chamber 50 can allow material to be preferably flowed into from stir chamber 40 in discharge nozzle 6.
In addition, in order to prevent that producing heat because of stirring-head stirring has influence on material, the present invention is in stirring set 4 and main valve body
Being provided between 20 on coolant jacket 7, the coolant jacket 7 has cooling chamber 70, and coolant is exactly to enter to enter material in the cooling chamber 70
Row cooling, so as to ensure that the quality of material is unaffected.In order that stirring set 4 is installed in rotation on the lower section of coolant jacket 7, this hair
Bright that bearing block 8 is provided with coolant jacket 7, bearing block 8 is provided with bearing 9, and stirring set 4 is just arranged on bearing 9.
In order to prevent material from being oozed out between coolant jacket 7 and stirring set 4, the present invention is set between coolant jacket 7 and stirring set 4
There is sealing ring 11.As shown in Fig. 2 the bottom of coolant jacket 7 is provided with antifriction upper working of plastics 10, the top of stirring set 4 is provided with anti-
The lower working of plastics 12 of friction, upper working of plastics 10 is fitted with lower working of plastics 12.Due to laminating, upper working of plastics 10 and lower 12 liang of working of plastics
Person can play sealed effect in itself, simultaneously because the reason for material, upper working of plastics 10 and lower working of plastics 12 are all very smooth,
So as to produce friction with coolant jacket 7 when effectively preventing that stirring set 4 from rotating, and upper working of plastics 10 or lower working of plastics 12 offer annular
Groove, sealing ring 11 is just matched in annular groove.
Finally it is worth mentioning that be cased with synchronizing wheel 3, the synchronizing wheel 3 is driven by timing belt 2 with motor 1 outside stirring set 4
Connection.The rotation of stirring set 4 is exactly to be driven by the motor 1.Certainly it can also be driven by other drive mechanisms, power here
Source is not rationed the power supply machine.
