Abstract
The utility model discloses a kind of anti-wire drawing sprue bush, comprising: sprue bush body, described sprue bush body interior is provided with fluid passage; Described sprue bush body is provided with Jiao Kou, and Jiao Kou is communicated with described fluid passage; On described sprue bush body excircle, the position of corresponding Jiao Kou has avoiding hollow groove.By the way, the utility model can improve radiating efficiency, and glue mouth temperature can effectively be controlled, and Jiao Kou place can wire drawing.
Description
Technical field
The utility model relates to injection machine accessory field, particularly relates to a kind of anti-wire drawing sprue bush.
Background technology
Sprue bush is a kind of device for plastic-injection field, its role is to connect injection machine and mould completes filling process.As shown in Figure 1, the heat of conventional apparatus main body can be transmitted to glue mouth 3 places fast by sprue bush body 1, glue mouth 3 temperature drifts, and after formed product is taken out, its end easily produces wire drawing phenomenon.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of anti-wire drawing sprue bush, the heat that can prevent body excessively passes to Jiao Kou place, increased contacting of sprue bush and air simultaneously, improves radiating efficiency, glue mouth temperature can effectively be controlled, and Jiao Kou place can wire drawing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of anti-wire drawing sprue bush is provided, comprises: sprue bush body, and described sprue bush body interior is provided with fluid passage; Described sprue bush body is provided with Jiao Kou, and Jiao Kou is communicated with described fluid passage; On described sprue bush body excircle, the position of corresponding Jiao Kou has avoiding hollow groove.
Preferably, described avoiding hollow groove cross section is " U " shape.
Preferably, described avoiding hollow groove cross section is circular arc.
The beneficial effects of the utility model are: the utility model can improve radiating efficiency, prevent the wire drawing of Jiao Kou place.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of sprue bush in prior art;
Fig. 2 is the sectional structure schematic diagram of anti-wire drawing sprue bush one preferred embodiment of the utility model;
Fig. 3 is the sectional structure schematic diagram of another embodiment of the anti-wire drawing sprue bush of the utility model
In accompanying drawing, the mark of each parts is as follows: 1, sprue bush body; 2, fluid passage; 3, Jiao Kou; 4, avoiding hollow groove.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 2 and Fig. 3, the utility model embodiment comprises:
In one embodiment, as shown in Figure 2, a kind of anti-wire drawing sprue bush, comprises sprue bush body 1, and described sprue bush body 1 inside is provided with fluid passage 2, and sprue bush end is provided with tapered groove, and sprue bush afterbody is provided with card key; Described sprue bush body 1 is provided with glue mouth 3, and glue mouth 3 is communicated with described fluid passage 2 and groove; On described sprue bush body 1 excircle, the position of corresponding Jiao Kou has avoiding hollow groove 4, and described avoiding hollow groove 4 cross sections are " U " shape." U " shape avoiding hollow groove 4 can prevent that the heat of body from excessively passing to Jiao Kou place, increased contacting of sprue bush and air simultaneously, improves radiating efficiency, and glue mouth temperature can effectively be controlled, and Jiao Kou place can wire drawing.
In another kind of embodiment, as shown in Figure 3, a kind of anti-wire drawing sprue bush, comprises sprue bush body 1, and described sprue bush body 1 inside is provided with fluid passage 2; Described sprue bush body 1 is provided with glue mouth 3, and glue mouth 3 is communicated with described fluid passage 2; On described sprue bush body 1 excircle, the position of corresponding Jiao Kou has avoiding hollow groove 4, described avoiding hollow groove 4 cross sections are circular arc, circular arc avoiding hollow groove 4 can prevent that the heat of body from excessively passing to Jiao Kou place, increased contacting of sprue bush and air simultaneously, improve radiating efficiency, glue mouth temperature can effectively be controlled, and Jiao Kou place can wire drawing; Circular arc avoiding hollow groove 4 can also reduce stress and concentrate.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
