Description
Technical field
The present invention relates to pvc pipe material head, especially relate to a kind of spreader pvc pipe material head.
Background technology
Mould plays a very important role realizing the requirement of plastic products processing technology, products appearance modeling requirement and other instructions for uses of goods.There is following defective in pvc pipe material head in the Vehicles Collected from Market: production efficiency is low, and it is large to extrude resistance; Material stream is inhomogeneous, produces easily shunt line; Tube wall thickness and material stream adjustment difficulty are large; The problems such as complex structure installation and maintenance difficulty.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of production efficiency high, extrude that resistance is little, material stream is even, the spreader pvc pipe material head of easy-maintaining simple in structure.
Purpose of the present invention can be achieved through the following technical solutions: a kind of spreader pvc pipe material head, it is characterized in that, comprise die body, die cavity, the mouth mould, spreader, spreader, core rod, core, pull bar, gland, described die body, die cavity and a mouthful mould connect and compose shell successively, described spreader, spreader, core rod and core connect and compose inner core successively, described inner core is positioned at described shell, and and shell between form the melt cavity, described gland is arranged on core one end, described pull bar is arranged on interior in-core, and pull bar one end is fixed on the gland.
Described outer surface of outer cover is provided with heater a.
Described die cavity and a mouthful mould junction are provided with the adjusting pressure ring.
Described core is the hollow core, and the madial wall of core is provided with heater b.
Described core rod is the hollow core rod, and the junction inwall of described core and core rod is provided with temperature transducer a.
Described mouthful of mould lateral wall is provided with temperature transducer b.
Be bolted between described die body and the die cavity, be connected by screw between spreader and the spreader.
The sidewall of described melt cavity all adopts the evanohm steel manufacturing of surface sclerosis and modifier treatment.
Compared with prior art, the present invention has the following advantages:
One, the scope of application is wide: this novel PVC tubing head has 8 kinds of specifications (FG63, FG110, FG160, FG200, FG250, FG400, FG630, FG800), can contain the pvc pipe material production line that covers diameter range 16～800mm.
Two, operating cost is low: directly all adopt the evanohm steel manufacturing of surface sclerosis and modifier treatment in this novel PVC tubing head with the parts of melt contact, this just means the mould damage that causes because of raw material local " thickener ", only just can remove fast by simple polishing, effectively reduce operating cost.
Three, simple to operate accurate: the simplification and the accuracy that in design process, just fully take into account operation.Bolt is convenient to each section of pipe die head and is assembled quickly and accurately.The die head dolly can conveniently be realized the Accurate align between die head and the production line.
Four, the runner design of optimizing: reasonably runner design guarantees that maximum extrusion capacity and melt have enough time of staying in die head, to eliminate the temperature contrast of melt; Through the spreader of streaming design, to guarantee smoothly flowing through of equilibrium of material; The mouth core is well-designed to promote that melt pressure is more balanced in the die head; Guarantee not collaborate the generation of line.
Five, molten temperature control is accurate: adopt the heating collar of independent control to guarantee the accuracy of each bringing-up section temperature on the die head.
Six, energy-saving and cost-reducing: the temperature control of die head core automatic heating is regulated the tube wall thickness fluctuation is minimized, to reach the purpose of conservation.
Description of drawings
Fig. 1 is the structural representation of spreader pvc pipe material head of the present invention;
Fig. 2 is the top view of spreader pvc pipe material head of the present invention.
Among the figure: die body 1, die cavity 2, mouthful mould 3, spreader 4, spreader 5, core rod 6, core 7, pull bar 8, gland 9, heater a10, heater b11, temperature transducer a12, temperature transducer b13.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
Shown in Fig. 1-2, a kind of spreader pvc pipe material head, comprise die body 1, die cavity 2, mouthful mould 3, spreader 4, spreader 5, core rod 6, core 7, pull bar 8, gland 9, described die body 1, die cavity 2 and a mouthful mould 3 connect and compose shell successively, and described die cavity 2 and mouthful mould 3 junctions are provided with regulates pressure ring 16.Described spreader 4, spreader 5, core rod 6 and core 7 connect and compose inner core successively, described inner core is positioned at described shell, and and shell between form the melt cavity, the sidewall of this melt cavity all adopts the evanohm steel manufacturing of surface sclerosis and modifier treatment, can effectively reduce the mould damage in the production process, described gland 9 is arranged on core 7 one ends, and described pull bar 8 is arranged on interior in-core, and pull bar 8 one ends are fixed on the gland 9.Described outer surface of outer cover is provided with heater a10, and under larger caliber, heater a is heating collar, is used for heating the head core.Described core 7 is the hollow core, and the madial wall of core is provided with heater b11, and heat sensor and connector are inserted in the middle of the core of hollow by the spreader supporting leg.Described core rod 6 is the hollow core rod, and described core 7 is provided with temperature transducer a12 with the junction inwall of core rod 6.Described mouthful of mould 3 lateral walls are provided with temperature transducer b13.
Be bolted between described die body and the die cavity, be connected by screw between spreader and the spreader.This head adopts the spreader supporting construction, and the spreader profile is streamlined, effectively avoids melt to stagnate thereon, is fit to very much process the PVC raw material very responsive to temperature.
PVC processing is a thermally labile process, needs fabulous runner.The PVC melt flows out from extruder and enters die body, and melt-flow is full of larger head and flows into subsequently around the support core.Core is fixed in the melt-flow by the spreader retainer.Melt-flow is by merging again after the spreader, the pvc pipe material that mouth mould and the core by different model processes different tube diameters and wall thickness.
During use, pvc pipe material head links to each other with the extruder adapter, and the fused materials that extruder is extruded flows into pvc pipe material head by the head adapter, the material die body of slowly flowing through, and die body separates melt, reduces its temperature and mechanical inhomogeneities.Flow through again spreader, die cavity, core rod, mouthful mould, core of melt forms the pipe embryo.Adjust heater a and the temperature of heater b change melt in head according to pipe embryo situation, make it to reach the optimal process temperature; As it is even to find to manage the germ wall thickness ununiformity, then adjusts the attachment screw a14 between spreader and the spreader and regulates pressure ring and adjust wall thickness with screw b15 between the mouth mould.
