(2) injection molding:
To the space injection moulding between core rod and former; During injection moulding, mould expanded by heating collar intensification expansion coefficient is large, produce the deformation quantity larger than metal section, the outer side wall of the collar forms arc convex, make between bellmouth madial wall and mould, to form " R " die cavity, in cooling procedure, the collar recovers normal gradually, " R " shape chamber absorbs outside air by air flue, and the collar is Teflon-like materials heat transfer is less than metal, pipe fitting herein temperature higher than other positions, so cooling meat is greater than other position of bellmouth herein, be beneficial to the further expansion of micro-R groove, final formation bellmouth micro groove; In cooling procedure, the collar recovers normal gradually, and former can realize the normal separation with injection molding pipe part.
Preferred according to the present invention, the outer side wall of step (1) described core rod is provided with groove, and the teflon collar is fixedly installed in described groove.
Preferred according to the present invention, the air flue described in step (1) embeds and is arranged on the described collar.
Preferred according to the present invention, the outer side wall place plane of step (1) the described collar is not higher than the outer side wall place plane of described core rod.
Preferred according to the present invention, control injection temperature during step (2) described injection moulding at 150 DEG C-250 DEG C.The temperature range of 150 DEG C-250 DEG C is lower than the softening temperature of the collar, and e.g., injection PVC, PE, PP pipe fitting, the highest injection temperature is lower than 250 degrees Celsius, and the guarantee teflon collar is indeformable.
Preferred according to the present invention, the mould described in step (1) also comprises cyclic water channel, and described cyclic water channel is arranged on collar footprint.Cyclic water channel can accelerate the reduction of teflon collar temperature.
Preferred according to the present invention, step (2) injected plastics material is PVC, PE or PP material.
Advantage of the present invention is:
1, micro-R groove bellmouth of the present invention no matter adopt which kind of mode carry out tubing connect all can prevent tubing from marking from bellmouth; Can be concordant with middle part for bellmouth root time gluing, to prevent gluing interface from slowly marking when solidifying, cause virtual connections;
Cushion rubber can be fixed in the bellmouth micro groove of 2, micro-R groove bellmouth of the present invention, have also been changed traditional bellmouth from oral area to root, the structural feature that bore reduces gradually, the join strength that bellmouth micro groove adds tubing and bellmouth effectively prevent pipeline skidding off from bellmouth; Be applicable to the Placement such as gluing connection, cushion rubber connection; Structure is simple, is easy to realize, and with low cost;
3, the production technology of micro-R groove bellmouth of the present invention, only simply need revise mould on the basis of existing mold, is easy to realize; Production process simple possible.
4, the character that the production technology of micro-R groove bellmouth of the present invention utilizes teflon itself to possess realizes course of working, and not needing increases manufacturing procedure, saving resource, safe and reliable, improves working efficiency.
