Corrosion in journey.
Description of the drawings
Fig. 1 is the structural representation of the mould of the injection bar pole in the present invention.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing and it is embodied as
Mode, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Invention, is not intended to limit the present invention.
A kind of manufacture method of injection bar, comprises the steps：
Step one：Mould is made, mould includes the mould of the mould and injection bar pole for being molded bar two ends lid.It is feasible
, the mould of two ends lid is cylindrical groove, and the lid of injection mo(u)lding is hollow circular cylinder shape.Referring to Fig. 1, it is this specific embodiment party
The mould structure schematic diagram of the injection bar pole in formula, which includes 2 cavitys, in other specific embodiments of the present invention,
Multiple cavities or a cavity can also be set, and cavity can be formed by upper and lower two parts mould matched moulds.Two ends are provided with placement
The groove of lid.Feasible, cavity both sides can be threaded groove for the screw thread being molded on bar.Can with, in the middle of cavity
Part can be used to be molded grip using dismountable handle cavity, handle cavity by be separately positioned on upper mould and under
Two pieces of square dies matched moulds on mould are formed, and two pieces of square dies of handle cavity are bolted with upper die and lower die respectively
Connection.Can be changed by demounting bolt, such that it is able to need to be molded by the handle of different anti-slip veins according to different.It is feasible
, handle both can be molded together with injection bar pole, it would however also be possible to employ the mode being molded respectively.The mould of injection bar pole
Upper die and lower die by arranging bolts hole at four angles, by upper die and lower die are fixed by bolt passing through bolt hole.
Step 2：Injection feed powder is prepared, advance load weighted resin-oatmeal and auxiliary agent are mixed.In order to not affect human body
Health, wherein the injection feed powder of injection pole can adopt polystyrene resins, Corvic or the poly- second of environmental protection
The mixture of olefine resin and auxiliary agent.The present invention other specific embodiments in, can also using polypropylene, ABS resin and
Other modified polymeric materials.As long as can be used as the injection feed powder of injection pole with plastic plastics.And
Lid needs also melt when pole is molded, therefore is molded the higher fusing point of pole needs, in the concrete of the present invention
