In the present embodiment; sealing protection device includes a pair arranging in relative shape and relative movement can realizing the fixture 46 opening and close; the top end face of fixture 46 forms bearing surface 6; fixture 46 is provided with the receiving chamber 41 that can accommodate container filling 7 main body, seals die cavity 312 when fixture 46 closes and abuts with shaping mould 31 to the container filling 7 main body molding mouth-sealed portion accommodated in chamber 41.
In the present embodiment, the controlling organization that fixture 46 can drive its relative shaping mould 31 to move up and down with is connected.Moved down with parison 21 by fixture 46, the movement travel of parison 21 can be retrained when extruded parisons 21, eliminate parison 21 and extrude the error of length, and the extrusion direction of parison 21 can be guided, it is ensured that the follow-up work such as molding, sealing is reliablely and stablely carried out.Certainly, to achieve these goals, also can be separately provided a positioner separated with fixture 46, move downward with the relative shaping mould 31 of parison 21.
In the present embodiment, the lower section of fixture 46 is provided with the die-cutting apparatus 5 for seal container 7 carries out stamping-out, and leaves the spacing moved up and down for fixture 46 between die-cutting apparatus 5 and shaping mould 31.So, the former parison 21 of the present embodiment is extruded, blow molding, stamping-out are all extruded at parison 21 and carried out on direction, it is not necessary to multiple bearing, and location is convenient, and overall structure is the compactest.
In the present embodiment, die-cutting apparatus 5 includes arranging in relative shape and relative movement can realizing the first clamping mould 51 and the second clamping mould 52 of opening and closing.Each clamping mould is provided with the stamping-out hole 53 highly adaptive with container 7, and being provided with in the stamping-out hole 53 of the first clamping mould 51 can be by moving horizontally the drift 55 in the stamping-out hole 53 stretching into the second clamping mould 52.On second clamping mould 52, the side away from the first clamping mould 51 is provided with the material-dropping hole 54 connected with stamping-out hole 53, by the container 7 after drift 55 stamping-out from material-dropping hole 54 discharging.
In the present embodiment, blow nozzle 1 includes the blowing jet pipe 11 for blowing and the fill nozzle needle 12 for fill, and fill nozzle needle 12 is sheathed in blowing jet pipe 11.So, after parison 21 is molded container 7 main body by blow nozzle 1, so that it may by fill nozzle needle 12 medium such as liquid drug in container 7 main body.
In the present embodiment, die device 3 in the vertical direction maintains static, and parison extrusion device 2 can vertically move back and forth so that parison extrusion device 2 can continuous extruded parisons incessantly, shorten the production cycle of plastic containers 7, improve production efficiency.Certainly, in other embodiments, in order to make parison extrusion device 2 can in whole production process continuous extruded parisons 21 incessantly, it is possible to being arranged to parison extrusion device 2 in the vertical direction and maintain static, die device 3 can vertically move back and forth.In a further embodiment, may also be arranged to parison extrusion device 2 and die device 3 in the vertical direction all maintains static, although efficiency is not as good as the present embodiment, but die device 3 and parison extrusion device 2 run more stable.
The work process of the present embodiment:
1, shaping mould 31, fixture 46, die-cutting apparatus 5 are in open mode, parison extrusion device 2 start continuously between two shaping moulds 31 extruded parisons 21(participate in Fig. 2)；
2, shaping mould 31 matched moulds, parison extrusion device 2 moves upward along with the extrusion of parison 21 simultaneously, and blow nozzle 1 moves downward and parison 21 blow molding in primary cavity 311 is gone out container 7 main body fill again (seeing Fig. 3)；
3, after completing fill, shaping mould 31 die sinking, blow nozzle 1 moves up to initial position, parison extrusion device 2 moves downwardly to initial position, container filling 7 bulk motion is at the receiving chamber 41 of fixture 46, then fixture 46 closes, and makes container filling 7 main body just be placed in receiving chamber 41 (seeing Fig. 4, Fig. 5)；
4, shaping mould 31 matched moulds, parison extrusion device 2 moves upward along with the extrusion of parison 21 simultaneously, blow nozzle 1 moves downward and parison 21 blow molding in primary cavity 311 goes out container 7 main body fill again, the sealing die cavity 312 container filling 7 main body molding mouth-sealed portion (seeing Fig. 6) to accommodating in chamber 41；
5, after completing fill, shaping mould 31 die sinking, blow nozzle 1 moves up to initial position, parison extrusion device 2 moves downwardly to initial position, fixture 46 moves downward one section of fixed length distance with seal container 7, makes the most canned container 7 main body accurate motion to fixture 46 at the receiving chamber 41 that initial position is corresponding (seeing Fig. 7)；
6, fixture 46 is opened, and is closed again after returning to initial position, makes container filling 7 main body at this just be placed in receiving chamber 41 (seeing Fig. 8)；
7, be repeated once step 4,5, now have seal container 7 to move at the stamping-out hole 53 of die-cutting apparatus 5 and (see Fig. 9 to Figure 11)；
8, drift 55 carries out stamping-out to the container 7 at stamping-out hole 53, and the container 7 after stamping-out is from material-dropping hole 54 discharging (seeing Figure 12 to Figure 14).
As shown in figure 15, in other embodiments, parison extrusion device 2 may also comprise two extruder heads 22 arranged in relative shape, the bottom of each extruder head 22 is provided with a lamellar extrusion 24 for extruding sheet parison 21 between two shaping moulds 31, and the lamellar parison 21 of two extruder head 22 extrusions can be located between two extruder heads 22 and can be stretched into blow nozzle 1 up or down.The quantity of blow nozzle 1 is corresponding with quantity and the position of the primary cavity 311 of lateral arrangement on shaping mould 31 with position, all of blow nozzle 1 is respectively positioned between two pieces of lamellar parisons 21 of two extruder head 22 extrusions, and two pieces of lamellar parisons 21 coordinate molding with multiple primary cavity 311 of lateral arrangement on shaping mould 31 simultaneously.Just one-shot forming can go out the container bottle row the most in a row by multiple containers 7 by two pieces of relative lamellar parisons 21, reduce the consumption of parison 21 material.
As shown in figure 16, in a further embodiment, the bottom of parison extrusion device 2 is provided with the oval tubulose extrusion 25 for the oval tubular parison 21 of extrusion between two shaping moulds 31.The quantity of blow nozzle 1 is corresponding with quantity and the position of primary cavity 311 on shaping mould 31 with position, and each oval tubular parison 21 is corresponding accommodates plural blow nozzle 1.Each oval tubular parison 21 coordinates molding with multiple primary cavity 311 of lateral arrangement on shaping mould 31 simultaneously.So, each oval tubular parison 21 just can mold the container bottle row the most in a row by two or more container 7, reduces the consumption of parison 21 material.
