Specific implementation mode
The utility model is further described below in conjunction with attached drawing embodiment.
As shown in Figure 1, 2, 3, Two-Stage Injection Device comprising spiro rod plasticizing mechanism 1, plunger injection mechanism 2, injection head 4,
Mold 5.
Above-mentioned spiro rod plasticizing mechanism 1 includes plasticizing foreboard 11, plasticizing back plate 12, plasticizing motor 13, plasticizing charging barrel 14, plasticizing
Screw rod 15, plasticizing placket 16, preceding drawing oil cylinder 19.
Above-mentioned plasticized screw 15 is placed in plasticizing charging barrel 14,15 front end 151 of plasticized screw can close plasticizing placket 16 into
Material mouth 161,15 rear end of plasticized screw are fixed with plasticizing 13 rotary shaft of motor, and plasticizing motor 13 is fixed in plasticizing back plate 12.
Oil cylinder 19 is drawn to be fixed in plasticizing back plate 12 before above-mentioned, the preceding piston rod 191 for drawing oil cylinder 19 is connected to plasticizing foreboard
On 11, by piston rod 191 it is flexible by move plasticizing back plate 12.
Above-mentioned plasticizing foreboard 11 is supported by pedestal 18, and guide rod 17 is fixed on plasticizing foreboard 11, and plasticizing back plate 12, which is sleeved on, to be led
On bar 17, it is plasticized back plate 12 in this way and pulls the when of moving forward that can be guided by guide rod 17 in preceding drawing oil cylinder 19, can move more stablely
It is dynamic.
Above-mentioned 11 bottom of plasticizing foreboard is also limited by inverted L-shaped locating part 10, preferably fixed plasticizing foreboard 11.
Feed inlet 161 is set in above-mentioned plasticizing placket 16, and shape and the shape of 15 front end 151 of plasticized screw coordinate, modeling
When change screw front end 151 resists feed inlet 161, salable feed inlet 161.
In the present embodiment, connecting tube 6 is also set up, one is connected to injection mechanism 2 by placket 16 is plasticized by connecting tube 6
It rises, also can be integral mechanism according to actual conditions, connecting tube 6 and plasticizing placket 16.
