End.Mold core is fixed in the cavity by mounting portion, and EPS material passes through mounting portion from via hole 7.2a, thus mounting portion has no effect on
EPS material moves in the cavity.
In the present embodiment, the rear end of second cylindrical portion 7.4 is provided with external screw thread 7.4a, and rear plug 8 is provided centrally with
The front of the mounting hole 8.1 being adapted with the second cylindrical portion, the mounting hole is unthreaded hole, and rear portion is provided with internal screw thread；Plug is logical afterwards
It crosses the internal screw thread to be threadedly coupled with the rear end of the second cylindrical portion, and is locked by lock screw 8.2.Herein, along diameter on rear plug
To threaded hole 8.3 is offered, the lock screw 8.2 is arranged in the threaded hole.The front-rear position of the rear plug of the structure can
It adjusts, to realize the adjusting of 9 width of gap, and then the EPS sheet material of different-thickness can be produced by the same molding die.And
It must be completed by rotary motion since rear plug will be moved forward and backward, the movement of the freedom degree is locked screw locking, so
The positional stability of plug is high afterwards.
Herein, the mold core 7 further includes the cone cell diversion division 7.5 that 7.1 front end of mounting portion is arranged in, and can reduce EPS material
The moving resistance of material in the cavity, it is ensured that the movement of EPS material is smooth.
Specifically, the core retainer plate 6 includes the preceding body 6.2 being connected with extruder, the middle set of body rear end before being connected to
Body 6.3, and it is connected to the rear body 6.4 of middle body rear end；Preceding body, middle body and rear body all have sub- cavity, these
Sub- cavity forms the cavity 6.1；The front end face of the rear end face of preceding body and middle body is provided with mounting groove and by the installation
Slot clamps the mounting portion 7.1 of mold core 7, as shown in Figure 5.
Preferably, annular slot 6.4a is offered on the circumferential surface of the rear body 6.4, rear body passes through two semicircle cards
Ring 6.5 is fixed on middle 6.3 rear end of body；One end of semicircle snap ring and annular slot are clamped, and the other end and middle body screw connect
It connects.Herein, semicircle 6.5 rear end of snap ring is provided with the raised 6.5a being adapted with annular slot 6.4a, protrusion 6.5a clamping
In annular slot.Since semicircle snap ring is detachable, the replaceable rear body with different inner diameters changes the size of runner,
To adapt to the production needs of different-thickness EPS sheet material.
See the second air blower 12 and electric cabinet that Fig. 9-11, the Blast mechanism E include rack 11, are arranged on the rack
13, the columned guide cylinder 14 being fixed at the top of electric cabinet, and the cutter 15 on rear side of guide cylinder is set；The guide cylinder
The outlet of molding die D described in the face of front end, be provided on guide cylinder a perforation front and back end blast pipe 14.1 and several
It is connected to the return-air hole 14.2 of front and back end；Second air blower connects the rear end of blast pipe by appendix 12.1；The cutter is used for
Cylindric EPS sheet material is cut from downside；Second air blower and electric cabinet are electrically connected, and control its work by electric cabinet.
With reference to Figure 11, the working principle of Blast mechanism E are as follows: (the curve in Figure 11 of drying forward in blast pipe after
The direction of arrow), the EPS sheet material of cone-shaped is blown to obtain tympanites, air-flow can flow out backward after knocking EPS sheet material from return-air hole
To guarantee that wind energy continues into, then the EPS sheet material after tympanites moves under the traction of winder along guide cylinder circumferential surface backward,
To which cooling and shaping is at cylindric sheet material, can be cut by cutter from downside when the sheet material of the cylindrical shape is moved to cutter location
Expansion.
Wherein, controller, control button and corresponding control circuit are provided in electric cabinet 13.Preferably, electric cabinet 13
It is inside additionally provided with frequency converter, to adjust the power of the second air blower 12, adapts to the production requirement of the sheet material of different-thickness.
Specifically, the guide cylinder 14 is made of antetheca, rear wall and circumferential wall, the blast pipe 14.1 be threaded through antetheca and
On rear wall, blast pipe rear portion is fixed on 13 top of electric cabinet, and antetheca and rear wall are provided with multiple return-air holes 14.2.Due to guide cylinder
It is hollow structure, weight is small, therefore can make cantilever-shaped setting at the top of electric cabinet, without extra support, so that it is guaranteed that
The process that sheet material is formed does not hinder.
Further, a round plate 14.3, the diameter and guiding of the round plate are additionally provided in front of the guide cylinder 14
The diameter of cylinder is equal；Round plate is made of rear wall and peripheral wall, and the blast pipe 14.1, which is worn, to be set on the rear wall of round plate, disk
Multiple return-air holes 14.2 are provided on the rear wall in portion.When only guide cylinder, fraction do not flow away from return-air hole and from
Flow away on the outside of circumferential wall, make sheet material can not adherent movement, to influence the shape of sheet material, after round plate is set, the part gas
Stream can the gap between guide cylinder and round plate come back in return-air hole, reduce the air-flow that flows away from outside, improve product
Quality.
In the present embodiment, it is provided with atomising device in the electric cabinet 13 and is conveyed by delivery pipe 16 toward guide cylinder front
Water mist, the delivery pipe are threaded through in the return-air hole 14.2 of guide cylinder.Due to from molding die come out EPS sheet material temperature compared with
Height, can heat guide cylinder keeps its temperature high, is unfavorable for the cooling and shaping of sheet material, by conveying water mist forward, cooled guide cylinder and
Sheet material promotes sheet material sizing；On the other hand the friction between sheet material and guide cylinder can be reduced, product quality is improved；In addition, can remove
Electrostatic.
In addition, the Blast mechanism E, further includes the guide rail 17 being arranged along the moving direction of EPS sheet material 90, the rack
11 are movably disposed on guide rail by idler wheel 11.1 and are locked on guide rail by lock screw 11.2.Corresponding different-thickness
Sheet material, demand is different the distance between from molding die to guide cylinder, and herein, the position of rack is adjustable, is suitable for difference
The production requirement of gauge sheet, it is with strong applicability.
See Fig. 1, atomizer H from water mist to EPS sheet material 90 and use for spraying are provided in front of the wrap-up G
In the blowing device I of drying EPS sheet material.It can further go to destatic by spraying water mist, and blowing device possesses handle and is sticked to EPS
Moisture drying on sheet material, which is preferably the blowing device of blowing hot-air.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
Bright design is subject to equivalent substitution or change, and all these changes or replacement all should belong to protection scope of the present invention.
