Description
Technical field
This utility model relates to operation, transport class, the mould that plastic extruding forming material passes through, espespecially a kind of plastic pipe
Vacuum shaping sleeve.
Background technology
Vacuum sizing is one of main method of plastic pipe shaping, and the purpose of vacuum sizing has two: one to be to obtain
Accurate physical dimension, another is for making plastics be pressed closely knit along tube wall, its principle be by set up tubing inner chamber with
Pressure reduction between wall makes pipe outer surface be attracted to calibration sleeve inwall, obtains external diameter and the satisfactory all size of wall thickness
Tubing, vacuum sizing method is commonly available to the tubing of the higher small dimension of line speed, and produces the tubing of big specification
The intrinsic pressure inflation sizing of general employing (being called for short intrinsic pressure sizing), intrinsic pressure sizing is to be filled with compressed air by inside tubing, makes plastic tube
Under gas effect, outer wall is attached to calibration sleeve inner surface, reaches the effect as vacuum sizing, and vacuum sizing is the simplest because of it
The safest and widely used, compared with intrinsic pressure sizing, vacuum sizing has the following advantages: (1) skirt is simple and quick, and waste material is few；(2)
In intrinsic pressure sizing method, compressed air remains in pipe, and along with being carried out continuously of producing, gas temperature constantly raises, and vacuum
Sizing air flows freely inside tubing, pipe material inner wall good cooling results；(3) dimensional tolerance can preferably be controlled；(4) pipe exists
Head outlet is in plastifying state almost without deformation；(5) internal stress of tubing is little；(6) danger not torn by plug screw；
(7) will not stop production because of plug screw abrasion；(8) machine head port mould separates with both vacuum sizing devices, thus temperature can individually control.
The sizing mode that the many employings of plastic pipe vacuum shaping sleeve of prior art are slotted on copper sheathing, due on copper sheathing
It is recessed in type-approval process the texture often causing outer surface of tube wall to produce strip, causes pipe outer surface rough, tubing
Circularity is bad, affects the presentation quality of tubing, causes the phenomenon that plastic pipe became uneven is even, affects follow-up use.
Summary of the invention
A kind of plastic pipe vacuum shaping sleeve, this equipment rule reasonable in design are provided for the problems referred to above this utility model
Model, easy to use, designed by the copper sheathing of hollow, can effectively control the weight of shaping cover, at copper sheathing indoor design heater strip
With cooperating of conduction oil, easily and effectively whole copper sheathing temperature can be controlled, increase the sizing stability of tubing, will
Conventional slot-like opening changes tiny through hole into, can effectively prevent from forming linear marking at pipe outer surface.
For solving the problems referred to above, this utility model provides a kind of plastic pipe vacuum shaping sleeve, including body, and copper sheathing,
Heater strip, through hole, it is characterised in that: being provided with the copper sheathing of hollow on body, be provided with flange on the left of copper sheathing, on copper sheathing, annular sets
Being equipped with some through holes, copper sheathing is internally provided with deep fat chamber, and deep fat chamber is provided with some heater strips, and deep fat chamber right upper portion is arranged
Fuel feed hole, deep fat chamber left lower is had to be provided with oil outlet.
As further improvement of the utility model, described copper sheathing inner surface is provided with white cast-iron layer, white cast-iron layer
Outside is evenly arranged with eight flanges, and copper sheathing inner surface respective flanges position is provided with groove, and groove is formed with flange and coordinates.
Operation principle:
This utility model is by being designed to manhole by original slot-like opening, outside effectively improving after tube forming
The smoothness on surface, after improving extruded velocity, the size of tubing has good stability, by being internally provided with at copper sheathing
Deep fat chamber and heater strip, can be increased to adaptive temperature by the temperature of shaping cover before starting to produce, effectively reduce product
Percent defective, can effectively ensure the stability of temperature simultaneously in process of production, copper sheathing inner surface is provided with spoken parts in traditional operas casting simultaneously
Iron layer, the effective wearability of energy, the service life of shaping cover can be greatly enhanced.
This utility model compared with prior art has the advantages that
1, this utility model is by being designed to manhole by original slot-like opening, after effectively improving tube forming
The smoothness of outer surface, after improving extruded velocity, the size of tubing has good stability, by arranging inside copper sheathing
There are deep fat chamber and heater strip, before starting to produce, the temperature of shaping cover can be increased to adaptive temperature, effectively reduce product
Percent defective, can effectively ensure the stability of temperature in process of production simultaneously, copper sheathing inner surface be provided with spoken parts in traditional operas simultaneously
Cast iron layer, the effective wearability of energy, the service life of shaping cover can be greatly enhanced.
