Application number is that 200810037592.9 Chinese invention patent " a kind of method of sealing glue along radial direction " discloses the method that a kind of pattern tool side and nozzle side fit fully and prevents leak-stopping glue, as shown in Figure 2.This patent does not need just can prevent by external impetus the leakage glue problem of injection machine, can avoid ending the pollution of external agency to fused materials simultaneously.But this patent requires injection machine nozzle and mould to be close to, and certain limitation is arranged in the use.
The utility model content
The purpose of this utility model is the defective at prior art, a kind of injection machine that is used for the processable polymer fused mass or spring side valve type spray nozzle device on the injection moulding tool of being contained in is provided, this spray nozzle device can be when spraying smooth opening, and spray the gap effectively closure prevent that fused materials from overflowing from spray material port.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: design a kind of spring side valve type spray nozzle device, comprising: body, fused materials input channel and be used to spray fused materials spray material port, be fixed in described body spool, form valve pocket that is slidingly matched and the spring that is used to support this valve pocket with this spool; Described spray material port is arranged on the front end of described valve pocket, has the valve pocket that is communicated with described spray material port between the front portion of described spool and the described valve pocket; Described spool is provided with fused materials runner that is communicated in described fused materials input channel and the spool bore that is communicated in described fused materials runner; Wherein, in the process of sliding with respect to described spool, described valve pocket has open position that is communicated with described spool bore and described valve pocket and the closed position of blocking described spool bore and described valve pocket.
Preferably, described spring can be arranged between described body and the valve pocket, and this spring can be the compression spring, and can be enclosed within on the described spool.
Preferably, described body has comprised adpting flange that can be connected in injecting machine material tube and the nozzle overcoat that is fixedly connected on this adpting flange, described fused materials input channel is positioned at described adpting flange inside, described adpting flange is fixed at the rear portion of described spool, and the front portion of described nozzle overcoat has the opening that can supply described valve pocket to stretch out.
Preferably, the front portion of described spool roughly is conical.
Compared with prior art, spring side valve type spray nozzle device of the present utility model makes the spool bore opening/closing by the relative motion of valve pocket and spool, and then realizes the opening/closing of spray nozzle device.Because the relative motion between valve pocket and the spool is by pressing in the locomotivity of the nozzle moving mechanism of injection machine and the fused materials and spring force is realized, so this spray nozzle device has the advantage that prevents flash,, raising injection-molded item quality pollution-free to fused materials.The action of the opening/closing of this nozzle can be automaticallyed switch in a production cycle of injection machine in addition, has the advantage low, reliable, that injection cycle is short of controlling cost.

The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Illustrated in figures 1 and 2 is a kind of preferred embodiment of the utility model spring side valve type spray nozzle device 1, and it has comprised adpting flange 3, nozzle overcoat 4, spool 5, compression spring 6, valve pocket 7 etc., and adpting flange 3 and nozzle overcoat 4 constitute the body of spray nozzle device 1.Adpting flange 3 is used for this spray nozzle device 1 is connected in the injecting machine material tube (not shown), and adpting flange 3 inside are provided with the fused materials input channel 2 that links to each other with the discharging opening of injecting machine material tube.The rear portion of nozzle overcoat 4 is fixedly connected on adpting flange 3 by modes such as screws, and the front portion of nozzle overcoat 4 has the opening that can supply valve pocket 7 to stretch out.Spool 5 is the shape that is similar to bullet, it is by tubular body portion 51 and roughly be conical anterior 52 and constitute, wherein, adpting flange 3 is fixed at the rear portion of this body portion 51, the inside of body portion 51 has fused materials runner 53, and the rear end of this material runner 53 is communicated in fused materials input channel 2, and body portion 51 is provided with spool bore 8 with the connecting portion of front portion 52, this spool bore 8 is communicated in fused materials runner 53, and radially penetrates spool 5.Have valve pocket 9 between the front portion 52 of spool 5 and the valve pocket 7, the front end of valve pocket 7 is provided with the spray material port 10 that is used to spray fused materials, and this spray material port 10 is connected with valve pocket 9.Compression spring 6 be enclosed within on the spool 5 and by cramping between the leading section of the rearward end of valve pocket 7 and adpting flange 3, these compression spring 6 and spool 5 concentrics.Valve pocket 7 and spool 5 form can before and after slide cooperate, compression spring 6 provides the resiliency supported effect for valve pocket 7.
As shown in Figure 3 and Figure 4, under the effect of the driving force F that the nozzle moving mechanism (standarized component that belongs to injection machine) by injection machine is provided, spray nozzle device 1 integral body moves right and close mould 11.Before valve pocket 7 touched mould 11, the inwall of this valve pocket 7 was with spool bore 8 sealings, and this moment, valve pocket 7 was in the closed position, was in the state that is blocked between fused materials runner 53 and the valve pocket 9, so fused materials can not flowed out by spray material port 10.When the spray material port 10 of valve pocket 7 with after the inlet 12 of mould 11 docks, owing to be subjected to stopping of mould 11, valve pocket 7 is moved to the left to open position with respect to spool 5, valve pocket 7 will compress spring 6 and compress when mobile, at this moment, the inwall of valve pocket 7 is opened spool bore 8, makes fused materials runner 53 and valve pocket 9 be in connected state, thereby fused materials can be expelled in the die cavity 13 of mould 11 again via spool bore 8, valve pocket 9 and spray material port 10 ejections from inlet 12.As shown in Figure 5 and Figure 6, after injection finishes, the nozzle moving mechanism of injection machine is moved to the left spray nozzle device 1 integral body by driving force F ' and away from mould 11, the valve pocket 7 that disengages with mould 11 is under the elastic force effect of fused materials internal pressure P and compression spring 6, with respect to move right closed position when initial of spool 5, the inwall of valve pocket 7 with spool bore 8 sealings, can prevent flash once more effectively.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from inventive concept of the present utility model; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
