Description
Technical field:
The present invention relates to blow moulding machine accessory technical field more particularly to a kind of blow molding machine head shunting disks.
Background technique:
After sealant is gushed out, using the wind-force produced by boasting, plastomer is blown to the die cavity for being attached to certain shapes, to be made
Product, this machine are just called blow moulding machine.
In the production process of blow molded product, the head of blow moulding machine needs to shunt melt, forms uniform tubular, so as to
It creates conditions for subsequent air blowing, molding.More common melt shunting mode is the outer plug of setting, in the circumference of outer plug
One-to-two, two point four, four point eight etc. of runner are set on wall, are looped around the outlet of each runner on the side wall of outer plug, into
And melt is made to form the tubular being looped around on outer plug side wall after runner, as shown in Figure 4.However, this traditional shunting
Mode generally requires outer plug and reaches longer axial length to be just able to achieve uniform divided flows, which results in head length it is whole compared with
It is long, not only make that blow molding machine head is more heavy, is not easy to assemble, also because of the larger entirety knot to blow moulding machine of blow molding machine head occupied space
Structure design causes larger limitation.
Summary of the invention:
In order to solve the above-mentioned technical problems, the present invention provides a kind of blow molding machine head shunting disk, length is relatively short and can
The other component of cooperation blow molding machine head processes melt composition cylindrical shape in order to subsequent blow molding.
The present invention is realized by following technical proposals:
A kind of blow molding machine head shunting disk, including disk body, characterized in that be provided with feed opening, the disk body one in the middle part of the disk body
End is provided with the helical groove for being looped around feed opening periphery on end face, and the depth ecto-entad of the helical groove successively decreases, institute
It states and is also provided with plup inlet on the side of disk body, the inner end of the plup inlet is connected to the outer end of helical groove.
In another aspect of the present invention, the cross section of the helical groove is that snail is linear.
In another aspect of the present invention, the helical groove is no less than 2 circles.
In another aspect of the present invention, the outer edge that the disk body is provided with an end face of helical groove is equipped with one
Boss is enclosed, the boss cross section is annular in shape.
In another aspect of the present invention, the height of the boss is 0.5cm.
In another aspect of the present invention, the disk body is integrally in cylindrical type.
In another aspect of the present invention, the depth of the helical groove outermost end is 1.5cm, and the helical form is recessed
The depth of slot inner terminal is 0.1cm, and the depth of the helical groove is uniformly successively decreased from outermost end to inner terminal.
The beneficial effects of the present invention are:
With outer plug is set in blow molding machine head and setting one-to-two, two point four, four point eight etc. on the circumferential side wall of outer plug
The conventional shunt mode of runner is compared, and this blow molding machine head can be realized in the plane with shunting disk allows melt to be looped around feed opening
Outside 2, so pass through feed opening 2 and with 2 inner wall of feed opening there are the cooperation of the columnar component of certain interval under make melt shape
At cylindrical shape, since the process for being looped around melt around feed opening 2 is realized in the plane, this blow molding machine head is used
For shunting disk it is not necessary that longer length is arranged in the axial direction, avoiding blow molding machine head because flow dividing structure length is larger leads to blow moulding machine
Head is more heavy, is not easy the problem of assembling, and avoids and sets because blow molding machine head occupied space is larger to the overall structure of blow moulding machine
Meter causes the problem of limitation.
