Description
Technical field
The utility model belongs to tubing and prepares technical field of tools, is specifically related to a kind of mouth die device for high melt point thermoplastic material extruding pipe material, is mainly used in pipe material product when material is extruded, temperature control being had to unique requirements.
Background technology
During general high melt point thermoplastic material extrusion molding, due to higher for fusing point, difficulty of processing is large.Meanwhile, its integral extrusion speed can not be very fast, in process, accelerate owing to contacting with air to lower the temperature, easily occur after high melt point thermoplastic material extruding pipe material that stress is concentrated, so also need after its regenerative ratio to carry out annealing operation, the mechanical property of guarantee tubing.
Summary of the invention
The utility model main purpose is to provide a kind of mouth die device for high melt point thermoplastic material extruding pipe material.Be intended to high melt point thermoplastic material by while mouth mold forming, by the control of temperature, extruded velocity, mouth mould length, make material complete annealing operation in shaping process, ensure that the perfection of tubing properties presents.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mouth die device for high melt point thermoplastic material extruding pipe material, comprise a mouthful mould main body, heat medium import/export, helical flow path, thermocouple slot, plug connector internal thread, plug connector external screw thread, mouth mould connector internal thread and mouth mould connector external screw thread, the axial hollow bulb of described plug is coolant guiding channel, in plug insert port mould main body, mouth mould main body coordinates with plug assembles the rear flow channel cavity forming melting charge, cavity size can coordinate the difference of mouthful mould inner major diameter and plug external diameter to determine as requested, both requirements keep with one heart, in the wall of mouth mould main body, helical flow path is set, heat medium enters from the heat medium import/export of helical flow path/flows out, mouth mould body outer wall establishes thermocouple slot, one end of mouth mould main body is provided with a mouthful mould connector internal thread, the other end of mouth mould main body establishes a mouthful mould connector external screw thread, one end of plug is provided with plug connector internal thread, the other end of plug establishes plug connector external screw thread, mouth mould main body and plug are more piece threaded connector.
Compared with prior art, the utility model has the following advantages:
Mouth mould main body and plug are the control of more piece threaded connector by temperature, extruded velocity, mouth mould length, and energy control temperature separately between each joint, make material complete annealing operation in shaping process, the perfection of guarantee tubing properties presents.

Detailed description of the invention
Below by accompanying drawing, the utility model is explained further.
As illustrated in figs. 2-7, a kind of mouth die device for high melt point thermoplastic material extruding pipe material, comprise a mouthful mould main body 8, heat medium import/export 1, helical flow path 2, thermocouple slot 3, plug 9, plug connector internal thread 4, plug connector external screw thread 5, mouth mould connector internal thread 6 and mouth mould connector external screw thread 7, the axial hollow bulb of described plug 9 is coolant guiding channel, in plug 9 insert port mould main body 8, mouth mould main body 8 coordinates with plug 9 assembles the rear flow channel cavity forming melting charge.In the wall of mouth mould main body 8, helical flow path 2 is set, heat medium enters from the heat medium import/export 1 of helical flow path 2/flows out, mouth mould main body 8 outer wall establishes thermocouple slot 3, one end of mouth mould main body 8 is provided with a mouthful mould connector internal thread 6, the other end of mouth mould main body 8 establishes a mouthful mould connector external screw thread 7, one end of plug 9 is provided with plug connector internal thread 4, and the other end of plug 9 establishes plug connector external screw thread 5, and mouth mould main body 8 and plug 9 are more piece threaded connector.
As shown in Figure 1, mouth mould is multi-section structure, counterpart mould carries out lengthening or shortening according to demand, often can carry out temperature control separately between joint, plug can carry out corresponding adjustment according to mouth mould size simultaneously, also can be multi-section structure, mouth mould can adopt heating jacket to carry out heating or adopt oil bath to heat, and between each joint, heating-up temperature is independent of each other.Can not connection breaking lengthen between mouth mould independently saves.First segment mouth mould main body is connected with head, and junction is set to tubaeform melting charge import.
Plug is hollow structure, can lengthen according to the actual requirements or shorten between each joint, and hollow structure mainly can carry out air auxiliary heating or cooling is used.
