Embodiment one: referring to shown in Figure 1; A kind of injection mold that possesses the nozzle self-centering apparatus; Comprise cover half 1, dynamic model 2, be in mould an actor's rendering of an operatic tune 3 between said cover half 1 and the said dynamic model 2, be located at the flow distribution plate 10 of said cover half 1 top, said flow distribution plate 10 possesses the resin service duct 12 more than that the molten resin that supplies outside supply passes through and will keep proper temperature through said resin service duct 12 inner molten resins and is arranged in a plurality of heating wire rods 13 around the said resin service duct 12; To optionally be supplied to the spray nozzle device 20 of said mould an actor's rendering of an operatic tune 3 to be installed in the nozzle installing hole 1a of said cover half 1 through the molten resin of said resin service duct 12.
Shown in Fig. 1～2; Said spray nozzle device 20 comprises that inside is provided with the nozzle body 21 of resin channels 22; The outlet of the nozzle needle 23 open said resin channels 22 on maximum lifting position in the said resin channels 22, the outlet of the said resin channels 22 of sealing is to nip off the resin supply on the maximum down position.The piston apparatus 30 of control said nozzle needle 23 oscilaltions is located at said flow distribution plate 10 tops and adjustable height.
14 li of the nozzle body engagement grooves of said flow distribution plate 10 bottom surfaces are fixed in through nozzle self-centering apparatus 40 in the upper end of said nozzle body 21, and insert in the said nozzle installing hole 1a that is arranged in the said cover half 1 lower end of said nozzle body 21.
As shown in Figure 2, said nozzle self-centering apparatus 40 comprises from top to bottom arranged in sequence in attaching parts 41, guard ring 43 and the guide ring parts 46 in the outside of said nozzle body 21.The nozzle body top threaded portion 21a that the inwall of the through hole of said attaching parts 41 is provided with the upper end of attaching parts threaded portion 41a and said nozzle body 21 is threaded.Inside, said guard ring 43 upper end is provided with the attaching parts accepting groove 43b that accommodates said attaching parts 41, and the lateral surface of said guard ring 43 is provided with guard ring and combines threaded portion 43a, is connected with said nozzle body engagement groove 14 inner threads.When the guard ring of said guard ring 43 combines threaded portion 43a and said nozzle body engagement groove 14 inwalls to screw fully; The attaching parts accepting groove bottom surface 43c of said attaching parts accepting groove 43b with accommodate said attaching parts 41 lower surface sliding-contacts within it, make said attaching parts 41 and said nozzle body 21 not can from 14 li of said nozzle body engagement grooves separate and with said flow distribution plate 10 no relative motions.
The inboard, bottom surface of said guard ring 43 is provided with one section taper shape the 1st centre pilot face 43d that falls in inward along central axis direction; Said the 1st centre pilot face 43d and conical the 2nd centre pilot face 46b that is located on the said guide ring parts 46 and more and more restrain along central axis direction from top to bottom are complementary; Through the cooperation between the 1st centre pilot face 43d and the 2nd centre pilot face 46b with the center-aligned of said guide ring parts 46 in the center of said guard ring 43, thereby alignd with the exit of said resin channels 22 in the center of said nozzle body 21.
The inwall of the central through hole of said guide ring parts 46 is provided with guide ring parts threaded portion 46a, is threaded with the nozzle body lower thread 21b of portion of said nozzle body 21.When said guide ring parts 46 rotate clockwise or counterclockwise will along said nozzle body 21 axially near or away from said guard ring 43.The lower outside face of said guide ring parts 46 is provided with center seating surface 46d, and said center seating surface 46d inserts said nozzle installing hole 1a and cooperates with nozzle installing hole inlet inwall 1b, keeps the center of said spray nozzle device 20 constant.
In addition, said guide ring parts 46 circumferencial directions are provided with a plurality of self-centerings affirmations and use through hole 46c.Said guide ring parts 46 are moved to said guard ring 43; Said the 2nd centre pilot face 46b is contacted with said the 1st centre pilot face 43d, confirm the centering state through insert said self-centering affirmation by the lower end with the insertion depth of the needle of through hole 46c under this state.
The self-centering process of the utility model: at first on said nozzle body 21, assemble said nozzle self-centering apparatus 40; Promptly put said guide ring parts 46, guard ring 43 and attaching parts 41 in order in the outside of said nozzle body 21; Be connected through screw thread the guide ring parts threaded portion 46a of said guide ring parts 46 with the nozzle body lower thread 21b of portion of said nozzle body 21, through said nozzle body top threaded portion 21a attaching parts 41 be fixed in the upper end of said nozzle body 21 then.
The said nozzle body that nozzle self-centering apparatus 40 is housed 21 insert in the nozzle body engagement grooves 14 and with the outside of said guard ring 43 and said nozzle body engagement groove 14 inwalls through being threaded; And make the bottom surface generation supporting role of the bottom surface 43c of said attaching parts accepting groove 43b to said attaching parts 41, can not separate the bottom of being fixed in said flow distribution plate 10 for 14 li thereby this moment the nozzle body 21 of said attaching parts 41 is housed with said nozzle body engagement groove.
Rotate said guide ring parts 46 and cooperate, thereby make the center, exit of resin channels 22 of center and said flow distribution plate 10 of the said nozzle body 21 of center-aligned of center and the said guard ring 43 of said guide ring parts 46 keep alignment until said the 2nd centre pilot face 46b and said the 1st centre pilot face 43d.
The spray nozzle device 20 that has alignd the center of nozzle body 21 and center, said resin channels 22 exit then is installed in the nozzle installing hole 1a of said cover half 1 with the assembly that flow distribution plate 10 is formed.
Then said guide ring parts 46 opposite spins that contact with said guard ring 43; Said guide ring parts 46 are moved to the direction away from said guard ring 43; The center seating surface 46d of said guide ring parts 46 and the nozzle installing hole of said nozzle installing hole 1a inlet inwall 1b contact matching make said nozzle body 21 be installed in the said cover half 1 with the self-centering state.
During injection moulding; Horizontal thermal expansion distortion (installation direction of spray nozzle device is horizontal relatively) takes place in the heat effect meeting that said flow distribution plate 10 receives heating wire rod 13 and high-temperature fusion resin; But dissolved by said guard ring 43 transverse movements; Can distortion not passed to said nozzle body 21, thereby the center of said nozzle body 21 remains unchanged.
Said nozzle self-centering apparatus 40 absorbs the horizontal thermal expansion of said flow distribution plate 10 and keeps the constant process in the center of said nozzle body 21 shown in Fig. 4～5: the profile that rear nozzle device and flow distribution plate are installed on the mould and keep aligned condition is accomplished in the centering of Fig. 4 embodiment one.Fig. 5 is that the nozzle self-centering apparatus absorption flow distribution plate thermal expansion distortion rear nozzle main body of embodiment one is kept the constant profile in center.
Shown in Fig. 4～5; When the horizontal thermal expansion of said flow distribution plate 10 generations is out of shape; The said guard ring 43 that is fixedly connected with said flow distribution plate 10 also and then laterally moves; Glade plane space C absorption between the inwall of said attaching parts accepting groove 43b and the lateral surface of said attaching parts 41 is out of shape the horizontal of said guard ring 43 that causes and is moved because of the thermal expansion of said flow distribution plate 10; The distortion that causes of thermal expansion can not influence the position of said attaching parts 41 like this, thereby the nozzle body 21 that said attaching parts 41 are housed can not receive the influence of thermal expansion distortion yet, keeps the centering state.
