Description
Technical field
A kind of plastic products manufacturing technology field is the utility model is related to, particularly a kind of EPE extruders foaming die.
Background technology
Screw-type extruder be by screw rod rotation caused by pressure and shearing force so that material be able to fully plasticizing with
And uniformly mixing, a kind of plastics machinery being molded by mouth mold, can just complete to mix simultaneously using an extruder, plastify with
And the series of process such as shaping, so as to continuously be produced, and cross-head is exactly the pass of extruder moulding process step
Key member.EPE (polyethylene foams) extruders are as one kind in numerous extruder types, its foaming machine in the prior art
Flange connecting seat, shunting disk, die head positioning seat and die cavity, each part mentioned above that head generally includes to be sequentially connected with connect to form head
Housing, middle part are hollow cavity, and locating shaft is arranged in the hollow cavity of head, and the axle center for being supported on shunting disk is installed on its head
On support, its afterbody suit die head, the cavity of flange connecting seat forms material feed cavity, between die head positioning seat and locating shaft
Cavity forms the mouth mold formation outlet plenum of forming cavity, die cavity and die head composition.From extruder screw part, output enters machine to material
Head feed cavity, by shunting disk after further heating plasticizing, plastic melt is changed into by screw move along a straight line into
Enter forming cavity, material, by heating, plasticizing, supercharging, is squeezed in the forming cavity by certain compression ratio design in mouth mold outlet plenum
Go out to obtain closely knit product.
In the prior art, EPE extruders foaming die is generally by the way of electric heating coil heating to feed cavity and forming cavity
Heated, this mode of heating has problems, for example heats uneven, unstable, heat time length, and uses
Electric spark is also easy to produce in journey and produces hidden danger, and Electrothermal ring can not carry out cooling operation to head, need to machine
When head is cooled, generally require manually to add water to cool, use is very inconvenient.
Utility model content
The purpose of this utility model is just to provide a kind of EPE extruders foaming die, and the EPE extruders foaming die solves
Electric heating coil heating is dangerous, uneven, unstable in the prior art, the heat time is long, temperature control not precisely, can not be quick
The problem of cooling.
The purpose of this utility model realizes that it includes by such technical scheme：
A kind of EPE extruders foaming die, including the circulation road formed by foaming die inner chamber, the stream passage bag
The feed cavity being sequentially connected and forming cavity are included, shunting disk is provided between the feed cavity and forming cavity, its innovation is：Institute
State feed cavity periphery and be provided with spiral oil wedge, the spiral oil wedge and feed cavity are separate, one end of the spiral oil wedge with
The input connection of first Oil-temperature control device, the spiral oil wedge other end are connected with the output end of the first Oil-temperature control device, institute
State in spiral oil wedge full of circulation fluid；The periphery of the forming cavity is provided with annular oil cavity, the annular oil cavity and forming cavity
Independently of each other, the annular oil cavity is connected by oil inlet with the output end of the second Oil-temperature control device, and the annular oil cavity passes through
Oil-out is connected with the input of the second Oil-temperature control device, full of circulation fluid in the annular oil cavity.
Preferably, the oil inlet of the annular oil cavity and the axial line of oil-out both pass through the axle center of the forming cavity
Line, and the axial line angle of the oil inlet and oil-out is more than 60 °.
By adopting the above-described technical solution, the utility model has the following advantages：Due to this EPE extruder foaming machines
Head circulates fluid by controlling oil temperature in spiral oil wedge and annular oil cavity enters trip temperature to realize to the melt in stream passage
Control, for oil pocket closer to stream passage, temperature control is sensitiveer, and the time of heating is short, saves the energy；And reduction can be passed through
Oil temperature carrys out cooling machine head, rapider, the relatively artificial plus water cooling more convenient operation so relative natural cooling cools；Pass through oil temperature
To control the temperature course of head stream passage not produce electric spark, the mode with respect to electric circle heating is safer；Pass through temperature control
Device processed can be precisely controlled oil temperature, with respect to electric circle heating more uniformly, stably.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows.
Fig. 1 is structural representation of the present utility model.
In figure：1st, feed cavity；2nd, forming cavity；3rd, shunting disk；4th, spiral oil wedge；5th, annular oil cavity；6th, oil inlet；7th, it is fuel-displaced
