Abstract
The invention discloses a kind of production technology of arc-shaped plastic material, the micelle including thermoplastic plastic, which dissolved by thermoplastic plastic plastic extruder and squeezed out by special mold molding, squeezes out the molding thermoplastic plastic material in cross section enters in cooling bay and camber that is thermoplastic plastic mud guard is sawed-off, producing mud guard with a chainsaw after squeezing out.The advantages of the present invention over the prior art are that: thermoplastic plastic material is reduced by extrusion process and is in the time in mold, material is avoided to turn to be yellow, extrusion process not will lead to thimble and print off on present plastic mud fender, make product surface more smooth, with the camber of regulating mechanism adjustment mud guard while coolant, the mud guard that same mold uniform machinery can make different cambers is suitable for different bicycles, reduce the production of mold, cost and more environmentally friendly is reduced, which can adjust camber range in diameter 40mm to diameter 85mm.
Description
Technical field
The present invention relates to bicycle mudguard field, in particular to a kind of production technologies of arc-shaped plastic material.
Background technique
The manufacture of present plastics bicycle mud guard uses the plastic mud fender of metal material or Shooting Technique, the disadvantage is that
One set of die is only capable of casting the mud guard of a kind of form size, camber, if desired manufactures the gear mud of onesize but different cambers
Plate then needs in addition to make mold, higher cost, needs when in addition casting technique injects the PVC of dissolution in process of production again
Certain time reaches integrally formed, causes PVC material to be easy jaundice, while having thimble and being imprinted on ready-made mud guard, causes
The mud guard surface manufactured is relatively rough, the entire effect good appearance degree of bicycle mud guard.
Summary of the invention
The technical problem to be solved by the present invention is to, provide in view of the above problems a kind of low manufacture cost production it is accurate can
The bicycle mudguard manufacture craft of deformation.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of production work of arc-shaped plastic material
Skill, the micelle including thermoplastic plastic, which is melted by plastic extruder and passes through special mold molding, to be squeezed out, squeezes out cross section
Molding thermoplastic plastic material enters in cooling bay and the arc-shaped plastic material of thermoplastic plastic is sawed with a chainsaw after squeezing out
Break, produce the camber of arc-shaped plastic material.
The advantages of the present invention over the prior art are that: by extrusion process reduce PVC material be in mold when
Between, avoid material from turning to be yellow, extrusion process not will lead to thimble and print off on present plastic mud fender, and make product surface more smooth,
With the camber of regulating mechanism adjustment mud guard while coolant, same mold uniform machinery can make different cambers
Mud guard is suitable for different bicycles, reduces the production of mold, reduces cost and more environmentally friendly, which can adjust camber range
In diameter 40mm to diameter 85mm.
As an improvement, the micelle of the thermoplastic plastic by plastic extruder heat, and by special mold at
Type extrusion is to put special mold into tighten in the outlet of plastic extruder, then passes through the plastics melt flow body in extruder
Mold squeezes out, to form the specific shape of arc-shaped plastic material.
As an improvement, the molding thermoplastic plastic material in the extrusion cross section enters in cooling bay, in cooling bay
It is recirculated water, it is ensured that water temperature is maintained at normal temperature state, maintains to cool down qualitative effect, while having guiding performance idler wheel to draw in cooling bay
Thermally conductive plastotype plastic material forms certain camber and squeezes out again from another outlet of cooling bay.
As an improvement, it is with a chainsaw that arc-shaped plastic material is sawed-off after the extrusion, basically form arc-shaped plastics
The first shape of profile.
As an improvement, the camber for producing arc-shaped plastic material, if desired arc-shaped plastics of different cambers
Profile then can fan the position adjustment of door by cooling bay inner guide pulley, pedestal and outlet position two to realize.
Specific embodiment
The present invention in the specific implementation, a kind of production technology of arc-shaped plastic material, it is characterised in that: including thermoplastics type
The micelle of plastics, which is melted by plastic extruder and passes through special mold molding, to be squeezed out, squeezes out the molding thermoplastics type in cross section
Plastic material enter in cooling bay and after squeezing out it is with a chainsaw that the arc-shaped plastic material of thermoplastic plastic is sawed-off, produce circular arc
The camber of shape plastic material.
The micelle of the thermoplastic plastic is heated by plastic extruder, and squeezed out by special mold molding be by
Special mold is put into and is tightened in the outlet of plastic extruder, then squeezes out the plastics melt flow body in extruder by mold,
To form the specific shape of arc-shaped plastic material.
The molding thermoplastic plastic material in the extrusion cross section enters in cooling bay, and in cooling bay is recirculated water,
Ensure that water temperature is maintained at normal temperature state, maintain to cool down qualitative effect, while thering is guiding performance idler wheel to guide thermoplastics type in cooling bay
Plastic material forms certain camber and squeezes out again from another outlet of cooling bay.
It is with a chainsaw that arc-shaped plastic material is sawed-off after the extrusion, basically form the first of arc-shaped plastic material
Shape.
The camber for producing arc-shaped plastic material, if desired the arc-shaped plastic material of different cambers, then may be used
It is realized with fanning the position adjustment of door by cooling bay inner guide pulley, pedestal and outlet position two.
The working principle of the invention: the micelle of PVC is dissolved by PVC plastic extruder, is then squeezed from the outlet of extruder
Out, and by special mold it is cooperatively connected in the outlet of extruder, this avoid the appearance of bubble, improve the matter of product
Amount squeezes out the molding PVC material in cross section and enters in cooling bay, and in cooling bay is recirculated water, it is ensured that water temperature is maintained at room temperature
State maintains to cool down qualitative effect, while having guiding performance idler wheel guidance PVC material to form certain camber again from cold in cooling bay
But another outlet in pond squeezes out, with a chainsaw that PVC mud guard is sawed-off after extrusion, has basically formed the first shape of mud guard, if desired
The mud guard of different cambers, then can fan the position of door by cooling bay inner guide pulley, pedestal and outlet position two, and decision produces gear
The camber of mud plate.
The present invention and its embodiments have been described above, this description is no restricted, it is illustrated above also only
It is one of embodiments of the present invention, actual structure is not limited to this.All in all if the ordinary skill people of this field
Member is enlightened by it, without departing from the spirit of the invention, is not inventively designed similar to the technical solution
Frame mode and embodiment, be within the scope of protection of the invention.
