The utility model comprises an adjustable inner core modular ring (1), a core (2), an inner core (3), a finish mold (4), an inner torpedo (5), a double channel bracket (6), a bracket (7), an adapting flange (8), an external heating device (9), a flow passage pipe for internal layer raw material transportation (10), a flow passage pipe for outer layer raw material transportation (11), a flow equalizing scroll cover (12), a shared flange (13), an internal heating device (14), a temperature probe (15), an adjusting screw (16), a clamping screw (17), etc.
Description
Technical field:
The utility model relates to metal material and plastics combined shaping tube apparatus, is specially a kind of composite pipe co-extrusion device.
Background technology:
The multiple tube co-extrusion device of known technology has a mouthful mould, core, interior core, support, mold etc., but the gap in it between core and the core is fixed, unadjustable, thus raw material after thawing because factor affecting such as temperature and pressure can cause the tube wall thickness of extruding inhomogeneous.Its internal layer raw material carries runner, hot melt adhesive material to carry runner to adopt same group of heating element heater and attemperating unit to control temperature, because the fusing point of PUR and tubing raw material, Vicat softening point etc. are different, so can't make PUR and tubing raw material reach best molten condition simultaneously.Its internal layer raw material carries flow-path tube and outer raw material hot melt adhesive material to carry the length of flow-path tube generally all shorter in addition, about 1.2 meters, can't satisfy long runner and carry requirement.
Summary of the invention:
Technical problem to be solved in the utility model is: provide the internal layer raw material that a kind of extruded product tubing is closely knit evenly, tube wall thickness can be adjusted, satisfied long runner conveying requires to carry flow-path tube and hot melt adhesive material to carry flow-path tube, and temperature is controlled easy multiple tube co-extrusion device.
In order to address the above problem; the utility model is achieved through the following technical solutions: be equipped with on interior core (3) and can adjust inner core modular ring (1); end in the cooperation place of interior core (3) and inner core modular ring (1) along interior core (3) radially is drilled with several screwed holes, and several are housed adjust screw (16).Be drilled with several axial holes at the end face that can adjust inner core modular ring (1) along circumference, can adjust inner core modular ring (1) with set bolt (17) and be fixed on the interior core (3).Be used to adjust the uniformity of inner tube product wall thickness.
The utility model can also carry the internal layer raw material flow-path tube (10), outer raw material to carry flow-path tube (11) to adopt arranged in concentric circles; Also can independently be separated into axis separately is arranged in parallel.And dispose corresponding independently heater (14), (9) and temperature probe (15), and make the length lengthening of carrying runner, reach more than 2 meters.Also make temperature control convenient and reliable.For making extruded product tubing closely knit evenly, shunting zone and compressional zone in the die head part have tapering respectively, increase current-sharing screw-casing (12) simultaneously in the runner corner, the binary channels support (6) of die head part and the passage place of support (7) are a plurality of supports, and the support radial section is streamlined or spiral wind blade profile and smooth surface.Current-sharing screw-casing (12) can be one start screw or multiple thread according to the caliber difference.
Compared with prior art, the invention has the beneficial effects as follows: because the inner core modular ring is housed, and can regulate annular gap between inner core modular ring and the interior core on interior core, thereby make the tube wall thickness of extruding more even by adjustment screw.Carry flow-path tube, outer raw material to carry flow-path tube to carry out temperature control respectively the internal layer raw material, make tubing internal layer raw material and outer raw material can both reach its optimum fusion temperature respectively, make temperature control easier, extrude better effects if, the mould scope of application is wider.
Description of drawings:
Figure one is an assembling schematic diagram of the present utility model
Among the figure: can adjust inner core modular ring (1), core (2), interior core (3), mouthful mould (4), interior minute flow cone (5), binary channels support (6), support (7), adpting flange (8), outer heater (9), internal layer raw material conveying flow-path tube (10), outer raw material conveying flow-path tube (11), current-sharing screw-casing (12), shared flange (13), inner heating device (14), temperature probe (15), adjustment screw (16) and trip bolt (17)
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Among the figure: can adjust inner core modular ring (1), core (2), interior core (3), mouthful mould (4), interior minute flow cone (5), binary channels support (6), support (7), adpting flange (8), outer heater (9), internal layer raw material conveying flow-path tube (10), outer raw material conveying flow-path tube (11), current-sharing screw-casing (12), shared flange (13), inner heating device (14), temperature probe (15), adjustment screw (16) and trip bolt (17).
Can adjust the annular space that the pipe plastics are extruded in constituting between inner core modular ring (1) and the core (2) among the figure; constitute the annular space that outer raw material is extruded between core (2) and mouthful mould (4); inner core modular ring (1) is adjusted annular gap between itself and the core (2) by adjusting screw (16); so that the tube wall thickness of extruding is more even, uses set bolt (17) to be fixed on interior core (3) after adjusting is finished again and upward get final product.The internal layer raw material carries flow-path tube (10) to connect inner heating device (14), and outer raw material carries flow-path tube (11) to connect outer heater (9), can carry out temperature control to it respectively by two temperature probes (15), and temperature control is more prone to.Increase current-sharing screw-casing (12) simultaneously in the runner corner, the binary channels support (6) of die head part and the passage place of support (7) are a plurality of supports, and the support radial section is streamlined or spiral wind blade profile and smooth surface.Current-sharing screw-casing (12) can be one start screw or multiple thread according to the caliber difference.The product tubing of extruding like this is closely knit evenly, and extruding of while tubing is effective.
