Description
Technical field
The present invention relates to the structure-design technique field of extrusion die, more specifically to a kind of tube forming equipment
Use extrusion die.
Background technology
The extrusion molding shaping of plastic products is a kind of relatively simple moulding process in plastic processing, and the method for the technique is
In the barrel for powdery or granular plastic resin raw material being added extruder, in the case where screw rod rotation, promoting, by raw material high temperature,
Melting charge is pushed into extrusion die by fusion plastification in condition of high voltage, the screw rod then continuously rotated again, is extruded from extrusion die
Be shaped to plastic products, then specification needed for through shaping and being cut into product, extrusion equipment generally comprise extruder and
Attached forming machine and cutting machine, combining form has a variety of, the processing of plastic products extrusion molding is continuously automatically performed.Wherein one
Plant plastic extrusion equipment and include extruder, vacuum setting machine and cutting machine, but found from actual production, the plastics are squeezed
Go out the plastic pipe presentation quality and density Shortcomings of former shaping.Engineering plastics of the prior art shown in Fig. 1
The mould of extruder includes upper mould 10, middle plate 30 and lower mould 20, and upper mould 10 includes the first compressional zone 11 and first and is cooled and shaped area
12；First compressional zone 11 is provided with the first heating hole 13；First cooling and shaping area 12 is provided with the first cooling water hole 14, lower mould 20
Area 22 is cooled and shaped including the second compressional zone 21 and second；Second compressional zone 21 is provided with the second heating hole 23；Second is cooled to
Type area 22 is provided with the second cooling water hole 24, and middle plate 30 is clipped between mould 10 and lower mould 20.In extrusion, melt body is noted
Enter die cavity, be compressed between the first compressional zone 11 and the second compressional zone 21 of mould, pass through the first heating hole 13 and second
Heating hole 23 is heated to mould, makes the certain viscosity of melt body holding to be compressed, by being arranged on the first cooling water hole
14 and the effect of the second recirculated water in cooling water hole 24, make product molding.Under normal circumstances, the mould of engineering plastics extruder
It is that steel is made, with preferable conductivity of heat.But, the first cooling and shaping area and the first compressional zone are an entirety, therefore, two
Influencing each other between person is also larger.Similarly, second cooling and shaping area and the second compressional zone between influence each other it is also larger.Cause
This, first is cooled and shaped area has cooling effect to the first compressional zone, and the second cooling and shaping area to the second compressional zone.This
Sample, in order to reach predetermined temperature, it is necessary to expend larger energy.Further, the temperature of the first compressional zone and the second compressional zone
Degree is higher, the first cooling and shaping area and the second cooling effect for being cooled and shaped area can again substantially reduced, so as to cause product
Yield rate is not high.In addition, the temperature in the heating part close to the first and second cooling and shaping areas is difficult to control, this can cause system
Often there is decorative pattern in product surface, so as to influence product quality.For problem above, a kind of reasonable in design is developed, it is convenient real
Tube forming equipment is those skilled in the art's technical problem to be solved with extrusion die.
The content of the invention
The technical problem to be solved in the present invention is：To overcome the technical problem mentioned in above-mentioned background technology, one is now provided
Plant reasonable in design, convenient and practical tube forming equipment extrusion die.
The technical solution adopted for the present invention to solve the technical problems is：A kind of tube forming equipment extrusion die, should
Mould includes：Extrusion port, with extrusion port be fixedly connected and section for T-shaped shaping cooling section, be arranged on extrude port and
The center-pole on cooling section axis is molded, the right side is provided with molded heat insulation section and gradually cooling section by a left side in shaping cooling section outside,
Molded heat insulation section and gradually it is provided between cooling section in heat dam, heat dam and is provided with thermal insulation board；The molded heat insulation section
Gradually by a left side, the right side is provided with the spiral cooling pipe road that internal diameter gradually increases in cooling section.
Further limit, center-pole external diameter described in above-mentioned technical proposal is less than the internal diameter of shaping cooling section.
Further limit, the section of molded heat insulation described in above-mentioned technical proposal and gradually cooling section are wrapped in outside shaping cooling section
Side.
Further limit, the is provided between the section left end of molded heat insulation described in above-mentioned technical proposal and extrusion port right-hand member
One rubber spacer, gradually by a left side, the right side is provided with the second rubber spacer and axle between shaping cooling section right-hand member left side on the right side of cooling section
To fastener.
Beneficial effect：Compared with prior art, the structure design of tube forming equipment extrusion die of the invention is more
Rationally, the setting of cooling pipe and heat dam, can be effectively reduced outside the temperature influence between shaping area and cooling zone, plastic pipe
Appearance quality and density qualities are preferable, convenient and practical, suitable further genralrlization application.
