Further, the production method for being molded bar further includes following steps, and detachable handle cavity is put into injection molding bar bar
It is fixed in the mold of son, the injection molding bar of injection molding is put into the mold of injection molding bar pole, is molded, and will be removable
It unloads handle cavity also to mold, injects injection molding material, naturally cool to molding, bar ejection will be molded by thimble.
The invention has the benefit that
The present invention first covers upper cover by the both ends of the former bar of injection molding bar and is molded again, to avoid in injection molding bar injection molding
The fabrication hole formed when completion in both ends or border, enhances the aesthetics of injection molding bar；And when being molded using steel pipe, lid
Son effectively can prevent plastics from entering steel duct, to effectively avoid waste raw material, and prevent plastics from entering
Steel duct increases weight；Furthermore by coating the both ends for being molded bar, it can effectively prevent injection molding bar from using
It is corroded in journey.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the mold of the injection molding bar pole in the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing and specific implementation
Mode, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are only to explain this
Invention, is not intended to limit the present invention.
A kind of production method being molded bar, includes the following steps:
Step 1: production mold, mold include the mold for being molded the mold and injection molding bar pole of bar both ends lid.It is feasible
, the mold of both ends lid is cylindrical groove, and the lid of injection molding is hollow cylinder shape.It is this specific embodiment party referring to Fig. 1
The mold structure diagram of injection molding bar pole in formula, it includes 2 cavitys, in other specific embodiments of the invention,
Also multiple cavities or a cavity can be set, cavity can be formed by upper and lower two parts mold clamping.Both ends are provided with placement
The groove of lid.Feasible, the settable thread groove in cavity two sides is used to be molded the screw thread on injection molding bar.Can with, among cavity
Part can using dismountable handle cavity for being molded grip portion, handle cavity by be separately positioned on upper mold and under
Two pieces of square dies on mould mold to be formed, and two pieces of square dies of handle cavity are bolted with upper die and lower die respectively
Connection.It can be replaced by demounting bolt, so as to according to the different handles for needing to be molded by different anti-skid chequers.It is feasible
, handle can be both molded together with injection molding bar pole, can also be by the way of being molded respectively.It is molded the mold of bar pole
Upper die and lower die are by being arranged bolt hole at four angles, by the way that upper die and lower die to be fixed bolt passing through bolt hole.
Step 2: preparing injection molding feed powder, and preparatory load weighted resin-oatmeal and auxiliary agent are mixed.In order to not influence human body
Health, wherein the injection molding feed powder of injection molding pole can be using polystyrene resin, Corvic or the poly- second of environmental protection
The mixture of olefine resin and auxiliary agent.In other specific embodiments of the invention, can also using polypropylene, ABS resin and
Other polymer materials being modified.It can be used as the injection molding feed powder of injection molding pole as long as having plastic plastics.And
Lid needs will not melt when be molded pole, therefore be molded the higher fusing point of pole needs, of the invention specific
In embodiment, the injection molding material for being molded pole can use the mixture of nylon and glass fibre.It is of course also possible to be other
Modified plastics material, as long as its fusing point is greater than the fusing point of the material of injection molding pole.
In addition, the auxiliary agent of injection molding material includes colorant, anti ultraviolet agent and plasticizer etc., wherein plasticizer is increased using environment-friendly type
Mould agent.
Step 3: it will be molded the feed powder heating melting of lid, the lid injection molding material of molten condition is injected into molding
In lid mold, molding is naturally cooled to, molding plastic closure is ejected, in other specific embodiments of the invention
The lid of injection formed can be taken out by other means, such as pass through clip and boom hoisting etc..
Step 4: the lid of forming is covered in the former bar of injection molding bar, feasible to incite somebody to action before covering upper cover
Burr removing on lid is conducive to improve injection molding effect.Both ends by being molded the former bar of bar first cover upper cover and are infused again
Modeling enhances the aesthetics of injection molding bar to avoid the fabrication hole formed when being molded bar injection molding and completing in both ends or border；And
When being molded using steel pipe, lid effectively can prevent plastics from entering steel duct, to effectively avoid waste
Raw material, and prevent plastics from entering steel duct and increase weight.Feasible, the former bar of injection molding bar can use solid round steel
Or steel pipe.Can effectively it reduce using when can effectively enhance the intensity for being molded bar when solid round steel, and use steel pipe
It is molded the weight of bar.
Step 5: by injection molding bar injection molding feed powder heating melting, the former bar for being cased with lid is put into the mould of injection molding bar pole
It is molded in tool, injects the injection molding bar injection molding material of melting, naturally cool to molding, ejected molding injection molding bar by thimble.
