Abstract
The utility model discloses a have the blowing is with central pan feeding formula head structure who shunts the structure, including the aircraft nose body, the internal runner that is provided with of aircraft nose, the tip of the aircraft nose body is the runner mouth, its characterized in that the detachable of runner mouth department is equipped with flow pipe, is equipped with the plug along flow pipe's length direction in the flow pipe, the plug with the same axle center of flow pipe, and the outer terminal surface of plug and flow pipe's outer terminal surface flushes, forms the subchannel between plug and the flow pipe, the inner of plug are fixed with the connecting plate open on the connecting plate have with the annular discharge orifice that the subchannel corresponds still can dismantle on the connecting plate is connected with the reposition of redundant personnel plug.
Description
Technical field
The utility model relates to blow moulding equipment field, is specifically related to a kind of blowing center pan feeding formula handpiece structure.
Background technology
Blowing is a kind of processing method of plastics, also claims hollow blow molding.The plastics being applicable to blowing have polyethylene, polyvinyl chloride, polypropylene etc., and the hollow container that blowing is produced is widely used as industrial packaging container.Blowing can be divided into extrusion-blown modling and injection-blow molding, and wherein extrusion-blown modling is most widely used.Blow moulding equipment mainly comprises extrusion device, injection device, the head of extruded parisons, the injection mould of parison, the mould of inflation, mold closing mechanism and feeder.Wherein, the parison handpiece of hollow blow molding is the vitals preparing parison, and its version, Selecting parameter etc. directly affect the quality of goods.At present, normally used head is divided into two classes: a class is direct extruded type parison handpiece, and another kind of is storage type parison handpiece.Direct extruded type parison handpiece mainly adopts center pan feeding and side direction pan feeding two kinds of forms.But the main deficiency that at present, center pan feeding formula parison handpiece exists is: 1. fluid is directly flowed out by the runner of a hollow substantially, shunts, flows out uneven, causes the container wall thickness uniformity of blow molding poor.
Utility model content
The utility model is intended to provide a kind of blowing center pan feeding formula handpiece structure with flow dividing structure.
Blowing in this programme center pan feeding formula handpiece structure, comprise handpiece body, runner is provided with in handpiece body, the end of handpiece body is runner mouth, it is characterized in that, be provided with flow-path tube described runner mouth place is dismountable, length direction along flow-path tube in flow-path tube is provided with plug, described plug and described flow-path tube concentric, and the outer face of plug flushes with the outer face of flow-path tube, runner is formed between plug and flow-path tube, the inner of plug is fixed with connecting plate, described connecting plate has the annular flow orifice corresponding with described runner, described connecting plate is also removably connected with shunting plug.
The beneficial effects of the utility model are as follows: the liquid material of blowing flows into via runner, via shunting plug and the shunting action of plug, evenly enter in runner, finally flow out from the shunting road junction of the outer end of flow-path tube and plug.Because the utility model devises flow dividing structure, therefore, the liquid material flowed out from runner can at the uniform velocity and the uniform die cavity flowing to mould towards different directions, and it is larger to there is disposable discharge, place's liquid material in mold cavity is caused to be filled, another place's also unfilled problem, the container mass of making is also higher.
Further, runner comprises first flow and and second runner that communicate vertical with first flow, and second road has the V-shaped enlarging in cross section, and the cross section of the inner of shunting plug is in the V-arrangement with the second runner cross-sections match.The cross section of the inner and the matching of the second runner of shunting plug, to reach better shunting effect, shunt evenly.
Further, the inner of flow-path tube has enlarging from outside to inside.Because the second runner has made the form of enlarging, therefore the enlarging of ecto-entad is made in the inner of flow-path tube, just in time contrary with the enlarging of the second runner, and to play the effect of flowing buffering to liquid, unlikely flowing is too fast, and makes blowing uneven.
Further, also comprise the adjusting bolt be threaded on handpiece body, the end face of described adjusting bolt and the inner lateral surface of flow-path tube offset.Adjusting bolt, for regulating the pipe diameter size of flow-path tube, when needing the caliber making flow-path tube to reduce formula, to reduce flow, by adjusting bolt to inward turning, inwardly can prop up flow-path tube, thus reaches the object of fine setting flow-path tube caliber.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: handpiece body 1, adjusting bolt 2, runner 3, flow-path tube 4, plug 5, ring flange 6, bolt 7, shunting plug 8, first flow 9, second runner 10.
Embodiment is substantially as shown in Figure 1: the present embodiment blowing center pan feeding formula handpiece structure, in stairstepping outside handpiece body, be provided with runner in handpiece body, runner is divided into first flow and and second runner that communicate vertical with first flow, and second road has the V-shaped enlarging in cross section.The end of handpiece body is runner mouth.
The present embodiment is provided with flow-path tube runner mouth place is dismountable, the connected mode of concrete flow-path tube is: the inner outside of flow-path tube has dome, the inwall of the second runner has annular groove, dome and annular groove offset, and be provided with ring flange in the outside of dome, the end face of ring flange and the lateral surface of dome offset, and ring flange is connected with handpiece body by bolt.
The inner of flow-path tube has enlarging from outside to inside.Length direction along flow-path tube in flow-path tube is provided with plug, plug and described flow-path tube concentric, and the outer face of plug flushes with the outer face of flow-path tube, runner is formed between plug and flow-path tube, the inner of plug is fixed with connecting plate, connecting plate has the annular flow orifice corresponding with described runner, connecting plate is also removably connected with shunting plug, the cross section of the inner of shunting plug is in the V-arrangement with the second runner cross-sections match.
Adjusting bolt is threaded on handpiece body, and the end face of adjusting bolt and the inner lateral surface of flow-path tube offset, and specifically offset with the outer face of dome.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
