Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
Embodiment 1：
As shown in Figure 1, a kind of novel PVC die for drainage pipeline, including shunting die holder 1, shunting die holder 1 are equipped with feeding mouth
11, the first spreader 12, the first spreader 12 form first flow 13, feeding mouth 11 and first flow 13 in shunting die holder 1
Connection shunts the right side of die holder 1 and is arranged with two pedestals 2 with the center line where the first spreader 12, and pedestal 2 passes through screw
It is fixedly connected with shunting die holder 1, the right side of two pedestals 2 is correspondingly provided with contraction set 3, and pedestal 2 is solid by screw and contraction set 3
Fixed connection, pedestal 2 are correspondingly provided with spreader 4 with 3 junctions of set are shunk, and spreader 4 forms second flow channel 21 on pedestal 2,
The correspondence of second flow channel 21 on pedestal 2 is connect with the end of first flow 13, and the right side for shrinking set 3 is correspondingly provided with mouth mold 5, mouth
Mould 5 is fixedly connected by screw with set 3 is shunk, and is equipped with mold core 6 in mouth mold 5, is formed third flow channel 7 between mold core 6 and mouth mold 5,
The correspondence of third flow channel 7 is connect with the end of second flow channel 21, and the lower section of mouth mold 5 is correspondingly provided with supported flange 8, supported flange
8 are fixedly connected by screw with set 3 is shunk.
Melt enters the first flow 13 of shunting die holder 1 by feeding mouth 11, will by the shunting function of first flow 13
Melt is divided into two strands by one, and from large to small, from depth to shallow, pressure gradually increases first flow 13 so that balanced point of melt
Stream enters the second flow channel 21 that is formed of spreader 4 by two pedestals 2, second 21 by melt appearance and size gradually from greatly to
Small transformation so that the further Dispersion Fusion of molecule between melt promotes melt strength, and melt, which enters to shrink by second flow channel 21, to be covered
The third flow channel 7 formed by gap between mouth mold 5 and mold core 6 on 3, melt carry out shaping in third flow channel 7, gradually by melt
Thin by thickness drawing, outer diameter from large to small, gradually stretches, and eventually arrives at the outlet forming of mouth mold 5；Wherein, it can be incited somebody to action by supported flange 8
Mouth mold 5, which is stablized, fixes.
In the present embodiment, melt enters mold by feeding mouth 11, and by the shunting function of shunting die holder 1 by melt
Two stock material streams are divided by one stream.From large to small, from depth to shallow, pressure gradually increases first flow 13 so that melt is balanced
Shunting, for ensure melt plasticizing while do not generate excessive resistance.When shunting the design of die holder 1, realizing that melt is uniform
Shunting under the premise of, shunting 1 longitudinal length L of die holder should shorten as possible, the increasing of channel as possible so that melt composition is larger
Back pressure but will not stop the long time, ensure loading sharing, the more conventional molds of length L for shunting die holder 1 shorten about 25%,
Sensible area increases by 10%.
In the present embodiment, spreader 4 for shunting die holder 1 can be given to provide certain operation back pressure, therefore is designed in design
When, under the premise of ensureing not causing melt imitation frosted glass, the straight channel volume should be minimized so that melt has larger fortune
Row back pressure, it is ensured that melt obtains good plasticizing in mold, and the 21 volume ratio traditional dies of second flow channel that spreader 4 is formed subtract
Few 20%.
In the present embodiment, should be under the premise of ensureing overall melt plasticizing when the design of sizing section, 5 hole size of mouth mold is answered
It is appropriate to increase, while increasing the annular space volume between mouth mold 5 and mold core 6, by this kind of mode, reduces melt and stopped in sizing section
Time increases discharging speed, to ensure that the speed of production of mold is further promoted.The more conventional mold of 5 outer diameter of mouth mold increases
15%, mouth mold 5 increases by 13% with 6 interstitial volume of mold core.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
It is exhaustive.All any modification, equivalent and improvement made within the spirit and principle of the present invention etc., should be included in
Within the protection domain of the utility model claims.
