Abstract
The invention discloses an anti-wire drawing cast gate sleeve including a cast gate sleeve body, the cast gate sleeve body is internally provided with a fluid channel; the cast gate sleeve body is provided with a glue outlet, the glue outlet is connected with the fluid channel; an empty avoiding groove is arranged on the external circumference of the cast gate sleeve body and is corresponding to the position of the glue outlet. By the way, the anti-wire drawing cast gate sleeve can improve the heat radiating efficiency, the glue outlet temperature can be effectively controlled, and wire drawing of the glue outlet can be avoided.
Description
Technical field
The present invention relates to injection machine accessory field, particularly relate 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.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anti-wire drawing sprue bush, can prevent that the heat of body from excessively passing to Jiao Kou place, has 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.
For solving the problems of the technologies described above, the technical scheme that the present invention 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 invention has the beneficial effects as follows: the present invention 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 present invention;
Fig. 3 is the sectional structure schematic diagram of another embodiment of the anti-wire drawing sprue bush of the present invention
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 invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 2 and Fig. 3, the embodiment of the present invention 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 embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention 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 invention.
Claims (3)
