Embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Provided by Fig. 1 and Fig. 2, the technical solution of the utility model is, including curved left valve pipe 2 and right valve pipe 4, institute
State left valve pipe 2 and right valve pipe 4 be mutually butted and form feed pipe 7 through pipe collar 3 and the fastening of screw 1, the left valve pipe 2 one of them
It is respectively equipped with the breach 8 of mutual cooperation on the interface of interface and the right valve pipe 4 connect in contrast, the breach 8 is along entering
The radial direction both ends open of expects pipe 7 and axially it is closed at both ends, the pipe collar 3 is placed on the feed pipe 7 at the both ends of breach 8, the charging
Wherein one end of pipe 7 blocks through plug 6, and the docking of two breach forms discharging seam 9, with the left valve pipe 2 diametrically of discharging seam 9 and
There are multiple boss 10 stretched out upwards respectively along axial arranged on right valve pipe 4, the boss on the left valve pipe 2 and right valve pipe 4
10 correspond and are fastened between boss 10 corresponding on left valve pipe 2 and right valve pipe 4 through bolt 11.It can be set on boss
Bolt passes through hole, and after bolt passes through, a nut being pressed on boss 16 is screwed in the other end relative to head of bolt,
Bolt head is pressed on another relative boss.
Provided by Fig. 3, docked between the left valve pipe 2 and right valve pipe 4 through labyrinth seal.The structure of described labyrinth seal
For：Engaging piece 12 and lower engaging piece 13 are respectively equipped with the interface except barbed portion of left valve pipe 2 and right valve pipe 4,
Upper engaging piece 12 and lower engaging piece 13 staggeredly engage during the docking of left and right valve pipe, on upper engaging piece 12 and lower engaging piece 13 can between
Every provided with multiple axial half slots 14（It is in be arranged laterally at a spacing in Fig. 1）, half slot 14 is axially through valve pipe, up and down engagement
Relative connect of the half slot 14 in portion forms circular seal hole, and being pressed in the circular seal hole has refractory seals bar 15.It is because close
Strip of paper used for sealing is refractory seals bar, therefore can bear the temperature of melt.
The depth of the breach 8 is 0.5mm-1mm, and two breach 8 form 1-2mm discharging seam 9 after docking（It is i.e. narrow
Seam）.The axial direction of discharging seam 9 is closed at both ends, and radial communication feed pipe 7 is inside and outside, width 1-2mm.
The outside of the radial section of feed pipe 7 is rounded, on the periphery of the described one end of feed pipe 7 away from plug 6
Provided with external screw thread.Feed pipe 7 is fixed on the upper mould side plate 5 of mould using external screw thread so that it is fixed conveniently quick, dismounting side
Just, the use of external screw thread is a kind of preferable fixed form, naturally it is also possible to be fixed by other known manners.
Pipe collar 3 of the present utility model can have multiple, and spacer sleeve is on feed pipe 7, but jagged 8 opening position is not set
Pipe collar 3 is put, pipe collar 3 is fixed after being enclosed on feed pipe through screw 1.
The utility model in use, whole melt feed pipe 7 is connected through a screw thread on the upper mould side plate 5 for being fixed on mould,
The one end for not having plug 6 is charging aperture, and there is 0.5-1mm breach 8 side of left valve pipe 2 and right valve pipe 4, in two valve pipes
1-2mm discharging seam 9 is formed after make-up, by discharging seam 9 towards lower placement, now discharging seam 9 is upper and lower penetrating, and longitudinal direction is wide
Spend for 1-2mm, axially closed at both ends, melt is entered in feed pipe 7 through charging aperture, is then uniformly fallen through discharging seam 9 in fibre
Tie up on one-way tape or in molten bath.The utility model uses discharging seam feed opening so that uniform blanking, continuous；Use flap-type
Feed pipe, simplify the difficulty of processing of mould, easy installation and removal；Using independent feed pipe, mold thickness is reduced, mitigates mould
The weight of tool.
After left and right valve pipe docking of the present utility model, pipe collar 3 is cased with the left and right valve pipe of 9 both sides of discharging seam, and is being gone out
Material stitches and multiple mutually corresponding boss 10 is arranged on the interface of 9 opposite sides, and the boss 10 between the valve pipe of left and right is through bolt 11
Tighten together, two corresponding boss 10 are arranged at intervals, the work of pretightning force of two corresponding boss 10 in bolt 11
With the lower left and right valve pipe by bottom being combined tightly, melt is avoided to be spilt from the joint in addition to discharging seam 9.It is excellent
The joint of the left and right valve pipe at except discharging seam 9 of choosing is arranged to labyrinth seal, further enhances of the present utility model
Sealing, the upper engaging piece 12 of its labyrinth seal can be arranged on the upside of the joint in addition to breach 8 of left valve pipe 2（
Upside is shown as in Fig. 3）, set along the left length direction of valve pipe 2, its lower engaging piece 13 can be arranged on right valve pipe 4 except
The downside of joint outside breach 8, set along the right length direction of valve pipe 4, the upper downside of engaging piece 12 and lower engaging piece 13
Upper side compresses docking, and the free end face of upper engaging piece 12 is to the end face of tight right valve pipe 4, and the free end face of lower engaging piece 13 is to tight
The end face of left valve pipe 2, also being compressed between upper and lower engaging piece by sealing hole has refractory seals bar 15, in pipe collar 3, boss
10th, in the presence of labyrinth seal, it is ensured that sealing of the present utility model, it is ensured that solution will not be from the left and right outside discharging seam
Valve pipe joint flows out.
The utility model dismounting is easy, uniform blanking, using independent feed pipe, reduces mold thickness, mitigates mould
Weight.
