The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment one: referring to shown in Figure 1; But a kind of injection mold that possesses the spray nozzle device of self-absorption thermal deformation; Comprise cover half 1, dynamic model 2, be in mold cavity 3 between said cover half 1 and the said dynamic model 2, be that media is installed flow distribution plate 10 with alignment pin 4 on the said cover half 1, said flow distribution plate 10 comprises main cast gate 11 that the molten resin with the outside supply injects, a plurality of supply the resin service duct 12 that the molten resin of main cast gate supply passes through and make the molten resin heating through resin service duct 12 and keep a plurality of heating wire rods 13 that are fit to injection temperature; This injection mold comprises that also the molten resin of high temperature-high pressure that said resin service duct 12 is provided optionally offers the spray nozzle device 20 of said mold cavity 3, is benchmark, is fixed on the said cover half 1 by the distance X of reserving with alignment pin 4.
Shown in Fig. 1～2; Said spray nozzle device 20 comprise an inside be provided with resin channels 32 and connect mould an actor's rendering of an operatic tune 3 nozzle body 30, can and the guard ring 50 of the upper end of nozzle body 30 the lining seat 40, fixing said nozzle body 30 and the said lining seat 40 that are slidingly connected, said lining seat 40 be contained in said flow distribution plate 10 the bottom surface and and nozzle body 30 on same central shaft.The upper end of said nozzle body 30 is provided with 40 spherical connecting portions 34 that are connected of ability and lining seat; Said lining seat 40 bottoms are provided with the ball recess 41 that can contact with spherical connecting portion 34 tight spheres; The transversely deforming of said guard ring 50 restriction lining seats 40, and keep the upper end of nozzle body 30 not separate with lining seat 40.
Said spherical connecting portion 34 upper edge circumferential circularize groove 34a, and cannelure 34a can absorb the transversely deforming power elasticity that flow distribution plate 10 thermal deformations cause.Put into sealing ring 35 in the cannelure 34a, prevent the gap to occur between the ball recess 41 of spherical connecting portion 34 and lining seat 40 of nozzle body 30 and leak glue.
The outer periphery of said nozzle body 30 is heated circle 36 and surrounds, and keeps the temperature through the molten resin of internal resin passage 32.
Said lining seat 40 comprises bottom surface along the axial embedding flow distribution plate 10 of said nozzle body 30, connected the joint portion, top 42 that the hold-down screw 46 of flow distribution plate 10 sides is fixed; Form said ball recess 41 outer wall, embrace the skirt section 43 of spherical connecting portion 34, be provided with the interface channel 47 that is communicated with resin service duct 12 and resin channels 32 in the said lining seat 40.The joint portion, top 42 of lining seat 40 and the bound fraction in skirt section 43 have sealing with step 48; As shown in Figure 3; Said sealed step 48 give below in conjunction with 34 pressurizations of spherical connecting portion, be close to the combined hole inwall, prevent the slit source glue of 12 of interface channel 47 and resin service ducts.
As shown in Figure 2, said guard ring 50 is a cylinder type, and screwed hole that the threaded portion 51 that the outside, upper end is provided with and flow distribution plate 10 bottom surfaces upwards form 14 is fixedly connected through screw thread.The upper end of guard ring 50 forms the skirt section 43 that upper end hole 52 is accommodated lining seat 40, and the lower end forms the upper end of accommodating nozzle body 30 with hole 52 coaxial following stomidiums 54, and the diameter of upper end hole 52 is greater than the diameter of following stomidium 54.
Said guard ring 50 lower end sidewalls circumferentially are provided with a plurality of perforation guard ring sidewalls and elasticity is propped up the spring plug 60 that is held in said nozzle body 30 outer surfaces.
The upper end of the resin channels 32 of said nozzle body 30 connects the end of the interface channel 47 of lining seat 40, and the lower end is connected with mold cavity 3 through cast gate 5.Central axis direction along said resin channels 32 is installed needle 33, and said needle 33 extends in the upper end of nozzle body 30 outward, is connected with valve actuator 70.Under the drive of valve actuator 70, when needle 33 dropped to bottom, the bottom front end was blocked cast gate 5, nipped off the resin supply to mold cavity 3; Opposite, when needle 33 rose to the extreme higher position, the bottom front end was opened cast gate 5, was mold cavity 3 supply resins.
As shown in Figure 4, said spray nozzle device 20, needle 33, valve actuator 70 are fixedly installed in respectively on the flow distribution plate 10, and with monolithic construction and assembling of said cover half or dismounting, on-the-spot simple installation, and installation period is short and do not need very high skilled operation degree.
In the injection molding process; Flow distribution plate 10 is heated wire rod 13 heating thermal expansions takes place, and causes transversely deforming, the cover half 1 that at this moment the is installed in flow distribution plate 10 belows device cooling that is cooled; Transversely deforming amount with respect to flow distribution plate 10 is little, so flow distribution plate 10 with respect to cover half 1 transversely deforming takes place.
Because the transversely deforming of flow distribution plate 10, the lining seat 40 that is fixedly connected with flow distribution plate 10 bottom surfaces also can laterally move, owing to be the sphere contact between the spherical connecting portion 34 of lining seat 40 and nozzle body 30, lining seat 40 can slide along the lateral surface of spherical connecting portion 34.
When lining seat 40 takes place laterally to move; The rear sidewall 43a that is positioned at the skirt section 43 at rear is hampered by the lateral surface that is positioned at its inboard spherical connecting portion 34; Receive the distortion of expansion laterally on the radial direction on the contrary; And the lateral surface in skirt section 43 is hampered by the madial wall of guard ring 50, so lining seat 40 can only be out of shape certain amount.Lining seat 40 slides with respect to the spherical connecting portion 34 of nozzle body 30; Move the position; Absorb the transversely deforming of flow distribution plate 10, and can not pass to nozzle body 30, prevent that nozzle body 30 from bending because of the transversely deforming of flow distribution plate 10; Avoid the slit occurring between nozzle needle and spray nozzle front end cast gate, guarantee injection-molded finished quality.
The transversely deforming of flow distribution plate 10 also can make the upper end of the guard ring 50 that is threaded with the flow distribution plate bottom surface that transversely deforming takes place; But the elastic recovering force of the spring plug 60 that install guard ring 50 bottoms makes the upper end of nozzle body 30 keep fixing position, does not receive the influence of the transversely deforming of guard ring 50.
Under the state that guard ring 50 and flow distribution plate 10 combine; When upwards tightening guard ring 50; The pressure that the spherical connecting portion 34 that lining seat 40 receives nozzle body 30 gives; Stage portion 48 more closely is adjacent to the upper side of the screwed hole 14 of flow distribution plate 10, prevents to leak glue through the gap of 12 of interface channel 47 and resin service ducts.
