Extrusion neck ring mold, the outer layer tape thickness of the extrusion neck ring mold extrusion molding is homogeneous, surface smoothness is high, and rate is bright the defects of burr, cut
It is aobvious to reduce.
The utility model adopts the following technical scheme that：
A kind of steel strip reinforced ripple outer tube layer band production extrusion neck ring mold, including the interior die body in rectangular-shape, it is described interior
Die body is made up of polytetrafluoroethylmaterial material and the middle part of interior die body is provided with the piece for extending along its length and running through in the width direction
Material extrusion cavities, the top of interior die body are provided with upper clamp, and the bottom of interior die body is provided with lower clamp, and the upper clamp and lower clamp are in
L-shaped and setting symmetrical above and below, the horizontal part of upper clamp are attached at the top surface of interior die body, and the horizontal part of lower clamp is attached at interior die body
Bottom surface, the vertical portion of upper clamp and lower clamp be attached at the trailing flank of interior die body and the vertical portion of upper clamp and lower clamp it
Between interval not less than the sheet material extrusion cavities vertical height.
Preferably, the interior die body is involuted up and down by two structure identical spill blocks, the recess of the spill block
Pairing forms the sheet material extrusion cavities.
Preferably, the spill block is provided with some the first fixing holes run through in the width direction, spill block along its length
Recess both sides be arranged with the second fixing hole run through along short transverse, the vertical portion of the upper clamp and lower clamp with it is described
The corresponding position of first fixing hole is provided with the 3rd fixing hole, the horizontal part and second fixing hole of upper clamp and lower clamp
Corresponding position is provided with the 4th fixing hole.
Preferably, the upper clamp and lower clamp are made of metal material.
The beneficial effects of the utility model are as follows：
Polytetrafluoroethylene (PTFE)（Polytetrafluoroethylene, it is abbreviated as PTFE）, it is this material high temperature resistant, antiacid anti-
Alkali, it is practically insoluble in all organic solvents.Meanwhile the coefficient of friction of polytetrafluoroethylene (PTFE) is extremely low, commonly referred to as " non-sticking lining "
Or " material easy to clean.During using traditional steel extrusion neck ring mold, the friction factor between steel and plastic sheet is 0.3 ~ 0.5, and
Friction factor between polytetrafluoroethylene (PTFE) and plastic sheet is only 0.04~0.12, it can be seen that, the utility model is by outer extrusion molding
The extrusion neck ring mold of machine is used instead in polytetrafluoroethylene (PTFE) after die body, effectively reduces frictional force during production outer layer band, abrasion resistance properties
Improve, for a long time using the abrasion deformation for being also not in sheet material extrusion cavities, thereby ensure that the outer layer belt surface of extrusion is bright and clean
Degree is high, thickness uniformity, and product quality is stable, and thus the surface of the compound obtained steel strip reinforced bellows of outer layer band is smooth,
Presentation quality is high, receives the generally favor of client.
