Description
Technical field
The present invention relates to extrusion technology field, more particularly to a kind of quick extrusion die of pvc pipe.
Background technology
In the market, the use scope of pvc pipe is wider, also relatively popularizes, when producing pvc pipe, is squeezed using extruder
Go out forming technique, during extrusion molding, by extrusion die formation pipe, pipe enters back into shaping box sizing after being extruded
Cooling, but be due to extrusion die temperature it is higher, can make pipe after being extruded by mould enter shaping box before in gravity
Effect is lower and deforms, and is unfavorable for the patterning process into shaping box.
Prior art carries out pre-setting using cooling tube is set in mouth mold, due to the limitation of structure, and cooling velocity is slow,
Efficiency is low, causes pre-setting effect poor, meanwhile, complicated, the attachment structure complexity of mould is not easy to remove and install, extruded
Shaping speed is low.
The content of the invention
The technical problem existed based on background technology, the present invention is proposed a kind of quick extrusion die of pvc pipe, removed and installed
Convenient, extrusion efficiency is high, and cooling velocity is fast, and pre-setting effect is good.
The quick extrusion die of a kind of pvc pipe proposed by the present invention, including mold base, divergent die and N number of shaping module, N >=2
Be provided with N bar runners in divergent die feed end and mold base clamping, divergent die, N number of shaping module respectively with divergent die discharge end
Clamping and corresponding with corresponding N bars runner position respectively；
Being molded module includes mouth mold and core, and core is arranged on inside mouth mold, and annular extrusion is formed between mouth mold and core
Passage；The helical pipe around extrusion passage arrangement, helical pipe edge extrusion passage feed end to discharge end are provided with mouth mold die body
Direction extends, and helical pipe is set to the first cooling medium inlet close to one end of extrusion passage discharge end, and the other end is set to first
Cooling medium is exported, and core is that coil pipe is provided with hollow structure, core, and coil pipe two ends each extend over out the first extension and second
Extension, the end of the first extension and the second extension away from coil pipe is extended to outside mouth mold through core and mouth mold, respectively
It is set to the second cooling medium inlet and the outlet of the second cooling medium.
Preferably, on the inside of mouth mold and on the outside of core, and polytetrafluoroethylene (PTFE) is equipped with close to the discharging opening position of extrusion passage
Coating.
Preferably, N number of shaping module is annularly arranged along divergent die.
Preferably, the part that the first extension and the second extension are located in extrusion passage is provided with heat-insulation layer.
Preferably, the first cooling medium inlet is located above mouth mold, and the outlet of the first cooling medium is located at below mouth mold.
The quick extrusion die of a kind of pvc pipe proposed by the present invention, will set mold base, and set divergent die feed end and mould
Have seat clamping, N number of shaping module and divergent die discharge end clamping, when being easy to follow-up more mold exchange or cleaning mould, remove and install
It is convenient；Multiple runners are set in divergent die, N number of shaping module is correspondingly arranged, make once extrudable many pvc pipes, production speed
Degree is fast, and extrusion efficiency is high；Set shaping mould group to include mouth mold and core, be respectively arranged to be passed through cooling in mouth mold and core
The helical pipe and coil pipe of medium, are cooled down to pipe, so as to realize pre-setting, prevent the pipe of extrusion from entering shaping box
Occur moderate finite deformation due to gravity before, be unfavorable for follow-up patterning process；According to actual extrusion, by helical pipe
The first cooling medium inlet is set to close to one end of extrusion passage discharge end, the other end is set to the outlet of the first cooling medium, logical
In the case of the flow direction for crossing above-mentioned cooling medium, it can be achieved to carry out different degrees of cooling to the pipe in extrusion passage, it is close
The cooling rate for extruding channel outlet is most fast, so that pre-setting effect is more preferable.
