Further improve as the utility model; Be provided with 4 water conservancy diversion covers in the said shell; Outwards be followed successively by the first water conservancy diversion cover around valve collar from the lining, around the second water conservancy diversion cover of first water conservancy diversion cover, around the 3rd water conservancy diversion cover of second water conservancy diversion cover, around the 4th water conservancy diversion cover of the 3rd water conservancy diversion cover, hot flow path from the lining outwards be followed successively by that second hot flow path between first hot flow path between first water conservancy diversion cover and the valve collar, first water conservancy diversion cover and second water conservancy diversion cover, second water conservancy diversion cover the 4th hot flow path, the 4th water conservancy diversion between overlapping with the 3rd hot flow path, the 3rd water conservancy diversion cover and the 4th water conservancy diversion between the 3rd water conservancy diversion cover overlaps and shell between the 5th hot flow path.
Compared with prior art; The utility model multilayer is total to the cost that the heat injection runner mechanism is simple in structure, can lower production obstruct bottle effectively; And at the bottom of the utility model multilayer obstruct bottle transparency that the heat injection runner mechanism is produced altogether, possess better physical property and more light-weighted advantage.
[description of drawings]
Fig. 1 is the utility model multilayer sectional structure sketch map of heat injection runner mechanism altogether;
Fig. 2 is the working state schematic representation of Fig. 1.
[specific embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2, for a kind of multilayer of the utility model is total to the heat injection runner mechanism, it is used for production multilayer high-barrier bottle base.
As shown in Figure 1, this multilayer altogether heat injection runner mechanism 1 comprises outermost shell 10, and be positioned at valve rod 11 that shell outwards is provided with from the lining successively, the valve collar that entangles valve rod 12, four water conservancy diversion covers that center on valve collar.These four water conservancy diversion covers are respectively around first water conservancy diversion of valve collar cover 13, around second water conservancy diversion cover 14 of first water conservancy diversion cover, around the 3rd water conservancy diversion cover 15 of second water conservancy diversion cover, around the 4th water conservancy diversion cover 16 of the 3rd water conservancy diversion cover.All keep at a certain distance away between each water conservancy diversion cover and with valve collar 12 and shell, thereby form five hot flow paths.Five hot flow paths are used to carry five kinds of materials.
Five hot flow paths be respectively the 3rd hot flow path 19, the 3rd water conservancy diversion between second hot flow path 18 between first hot flow path 17 between first water conservancy diversion cover 13 and the valve collar 12, first water conservancy diversion cover, 13 and second water conservancy diversion cover 14, second water conservancy diversion cover the 14 and the 3rd water conservancy diversion cover 15 overlap the 15 and the 4th water conservancy diversion overlap the 4th hot flow path 20, the 4th water conservancy diversion between 16 overlap 16 and shell 10 between the 5th hot flow path 21.
The top of shell 10 and each water conservancy diversion cover is equipped with valve nozzle, and five hot flow paths communicate with each valve nozzle.The valve nozzle of each water conservancy diversion cover and shell is passed on the top of valve rod 11 successively, and the valve nozzle of each water conservancy diversion cover is passed on the top of valve collar 12.The top of valve rod 11 is stretched into the valve nozzle of shell 10 and is controlled the switch of the valve nozzle of shell 10, and the top of valve collar 12 is stretched into the valve nozzle of each water conservancy diversion cover and controlled the switch of each water conservancy diversion cover valve nozzle.That is, the top of valve rod 11 is used to seal or opens the 5th hot flow path 21, and valve collar 12 is used to seal or opens the 4th hot flow path 20, the 3rd hot flow path 19, second hot flow path 18 and first hot flow path 17.
Below shell 10, also be provided with an airtight chamber 22.Thereby be provided with a tabula 23 in this chamber 22 with two cylinders of chamber 22 classification, for: first cylinder 24 and second cylinder 25.Be provided with in first cylinder 24 in first piston 26, second cylinder 25 and be provided with second piston 27.The end of valve rod 11 links to each other with first piston 26, the terminal of valve collar 12 links to each other with second piston 27.
As shown in Figure 2, be the working state schematic representation of the common heat injection runner mechanism 1 of the utility model multilayer.This multilayer heat injection runner mechanism 1 altogether is used five layers of bottle embryo of production high-barrier with preform mould 2.
When first cylinder 24 is opened, first piston 26 drives valve rods 11 and moves down, the 5th hot flow path is opened, and material A is injected mould 2 from the 5th hot flow path.When reaching the electronic ruler operation displacement of setting, open second cylinder 25; Second piston 27 drives valve collar 12 and moves down; The 4th hot flow path, the 3rd hot flow path, second hot flow path, first hot flow path are opened in succession, and other four layers of material B, C, D, E inject in the mould 2, begin five layers and annotate altogether; When reaching the electron displacement of setting, close each hot flow path in succession.
The utility model multilayer is total to the cost that the heat injection runner mechanism is simple in structure, can lower production obstruct bottle effectively; And at the bottom of the utility model multilayer obstruct bottle transparency that the heat injection runner mechanism is produced altogether, possess better physical property and more light-weighted advantage.
Above-described only is the embodiment of the utility model; Should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; Can also make improvement, but these all belong to the protection domain of the utility model.
