Wax injector
Technical field
The present invention relates to a kind of wax injector.
Background technology
Wax injector is most important equipment during processing of ornament makes, and is mainly used in toward casting in mold box, general streamline
The wax injector of formula is needed ceaselessly toward casting in different mold boxes;Wax injector includes wax cylinder and casting nozzle, at interval
Between long casting action when, the wax in mouth can solidify quickly, be easier problem appear to is that hawfinch is lived by paraffin blockage,
So, have two it is very serious the problem of, 1, wait hot wax to melt the cold wax blocked needing many times.2nd, mill is easily caused
Wax in tool is noted not exclusively not thorough.
The content of the invention
It is an object of the invention to overcome disadvantages described above, there is provided a kind of wax injector.
To achieve the above object, concrete scheme of the invention is as follows:A kind of wax injector, include wax cylinder and casting nozzle;
The casting nozzle includes the first casting mouth structure and is arranged the second casting mouth structure of the first casting mouth structure;Described first
Casting mouth structure includes the first pipeline, and the first pipeline top is provided with the casting head of taper;First pipeline is provided with two symmetrically
The the first rectangle windowing set;The second casting mouth structure includes second pipe, and the outer wall afterbody of second pipe is provided with one
Gear teeth structure is enclosed, the second pipe is provided with two symmetrically arranged second rectangle windowings;Set on the second pipe inwall
Have two it is symmetrically arranged convex stupefied, the face of the convex stupefied close axle is cambered surface, and the cambered surface is concave surface, radian and the first pipeline appearance
Face radian is identical, and the chord length of the cambered surface is more than the width of the first rectangle windowing;The length and width difference of second rectangle windowing is big
In the length and width of the first rectangle windowing;Also include at least one gear, each gear is engaged with gear teeth structure, also wrapped
Include the stepper motor of drive gear rotation;Also include push cylinder on one, upper push cylinder clutch end, which is provided with, to be used to incite somebody to action
The wax of solidification releases the rectangle pushing block of casting nozzle, the length and width of rectangle pushing block from the windowing of the first rectangle and the windowing of the second rectangle
Degree is respectively smaller than the length and width of the first pipeline.
Wherein, the second rectangle windowing connects with the top of second pipe.
Wherein, the first pipeline tail end is provided with helicitic texture.
Wherein, gear teeth structure and second pipe are formed in one, and are metal material.
Beneficial effects of the present invention are:Pass through the first casting mouth structure and the second wax injection nozzle for being arranged the first casting mouth structure
Structure;And windowing, just the second casting mouth structure of rotation and then solid wax is moved back with pushing block every few seconds between realizing after each casting
Go out.After rotating again, new hot wax can reach mouth quickly, prevent from blocking.

Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not the reality the present invention
Apply scope and be confined to this.
As shown in Figures 1 to 7, a kind of wax injector described in the present embodiment, wax cylinder a and casting nozzle b are included;The note
Wax nozzle b includes the first casting mouth structure and is arranged the second casting mouth structure of the first casting mouth structure;First casting
Mouth structure includes the first pipeline 11, and the top of the first pipeline 11 is provided with the casting first 13 of taper;First pipeline 11 is provided with two
Symmetrically arranged first rectangle windowing 12;The second casting mouth structure includes second pipe 21, the outer wall of second pipe 21
Afterbody is provided with a circle gear teeth structure 24, and the second pipe 21 is provided with two symmetrically arranged second rectangle windowings 22;It is described
It is cambered surface that the inwall of second pipe 21, which is provided with two symmetrically arranged convex stupefied 23, described convex stupefied 23 close to the face of axle, and the cambered surface is
Concave surface, radian is identical with the outer surface radian of the first pipeline 11, and the chord length of the cambered surface is more than the width of the first rectangle windowing 12;Second
The length and width of rectangle windowing 22 is respectively greater than the length and width of the first rectangle windowing 12;Also include at least one gear
5, each gear 5 is engaged with gear teeth structure 24, also includes the stepper motor of the rotation of drive gear 5;Also include on one
Push cylinder 3, the upper clutch end of push cylinder 3, which is provided with, to be used to release the wax of solidification from the windowing of the first rectangle and the windowing of the second rectangle
The rectangle pushing block 4 of casting nozzle, the length and width of rectangle pushing block 4 are respectively smaller than the length and width of the first pipeline 11.
Concrete operating principle is as follows:During casting, convex stupefied 23 on the inwall of second pipe 21 cover the first rectangle
Windowing 12, allow the first pipeline 11 formed a complete casting passage, after the completion of casting, due to interval time it is long when,
Wax in first pipeline 11 solidifies after cooling down rapidly, and when starting second of casting, driving stepper motor gear 5 rotates, tooth
The driving gear teeth structure 24 of wheel 5 is rotated, and so as to have rotated second pipe 21, after being rotated by 90 °, the second rectangle of second pipe 21 is opened
Window 22 just targeted by the first rectangle windowing 12, form a vertical passage, and now upper push cylinder 3 promotes rectangle pushing block 4 by wax
Push out;Then, pushing block returns to original position, forms a cavity in the first pipeline 11, second pipe 21 turn 90 degrees, returned to convex stupefied again
The position of 23 the first rectangle of covering windowings 12, although now there be a small amount of existing solid wax on the head of the first pipeline 11, greatly
The hot wax of amount can also melt a small amount of solid wax retained after entering out of first pipeline 11.Therefore can effectively solve paraffin blockage to live
The problem of passage, daily maintenance is also very simple in addition.
In described in the present embodiment, the second rectangle windowing connects with the top of second pipe 21.Rational in infrastructure, can
Easily to dismantle.
In described in the present embodiment, the tail end of the first pipeline 11 is provided with helicitic texture.Facilitate the tail end of the first pipeline 11 and wax
The wax outlet of cylinder is connected.Gear teeth structure 24 and second pipe 21 are formed in one, and are metal material.
Pass through the first casting mouth structure and the second casting mouth structure for being arranged the first casting mouth structure;And windowing, realize
Just then the second casting mouth structure of rotation is exited solid wax with pushing block every few seconds between after each casting.After rotating again, new
Hot wax can reach mouth quickly, prevent from blocking.
Described above is only the preferred embodiment of the present invention, therefore all structures described according to present patent application scope
Make, the equivalent change or modification that feature and principle are done, in the protection domain of present patent application.
