Existing extrusion die is single module, need to change different extrusion dies when dissimilar plastics are extruded by extruder, has increased production cost.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of combined type assembling extrusion die that is applicable to different plastic extrusions.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Combined type assembling extrusion die, comprise that one is used for and the feed module of extruding barrel and being connected, it is characterized in that, also comprise: material discharging module that is used for final extrusion molding, be used for being arranged on being used between above-mentioned feed module and material discharging module and realize extruding and form the more than one transition module of regulating; Above-mentioned feed module is provided with a plurality of feeding-passages, and above-mentioned material discharging module is provided with a plurality of tapping channels, and above-mentioned transition module is provided with a plurality of for being communicated with corresponding above-mentioned feeding-passage and the transition passage of tapping channel; Above-mentioned transition module is formed with a plurality of positioning convex or/and cave in the location with the end face that above-mentioned feed module and material discharging module join, corresponding location depression and the positioning convex that coordinates with positioning convex and the location depression of above-mentioned transition module that be formed with of above-mentioned feed module and material discharging module.
Further, the outer rim of above-mentioned feed module, material discharging module, transition module is provided with for fixing ring flange.
Wherein, above-mentioned feeding-passage, transition passage, tapping channel are one to one.
Perhaps, above-mentioned feeding-passage, tapping channel are one to one, and above-mentioned transition passage is that one-to-many is corresponding with them.
Further, above-mentioned transition passage is cylindrical hole, and above-mentioned feeding-passage, tapping channel are the truncated cone through hole, and the two ends of above-mentioned transition passage are formed at above-mentioned positioning convex or/and above-mentioned location depression.
Usefulness of the present utility model is: the transition module is set between feed module and material discharging module, can increases or reduce the transition module and regulate extruding of plastic melt according to the characteristic of plastic melt easy and simple to handle, saving cost.
Description of drawings
Fig. 1 is the structural representation of combined type assembling extrusion die of the present utility model.
The implication of Reference numeral in figure: the 1-feed module, the 11-feeding-passage, the 2-material discharging module, the 21-tapping channel, 3-transition module, the 31-transition passage, the 4-ring flange, the 5-positioning convex, 6-locates depression.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done concrete introduction.
Combined type assembling extrusion die as shown in Figure 1 comprises: feed module 1, material discharging module 2, transition module 3.Be fixed together by ring flange 4 between feed module 1, material discharging module 2, transition module 3.Wherein, feed module 1 is used for and extrudes barrel and be connected, and material discharging module 2 is used for the final extrusion molding of plastic melt, and transition module 3 is used for regulating extruding of plastic melt, and quantity is more than one.
Feed module 1 is provided with a plurality of feeding-passages 11, and material discharging module 2 is provided with a plurality of tapping channels 21, and transition module 3 is provided with a plurality of transition passages 31, and transition passage 31 is used for connecting feeding-passage 11 and tapping channel 21.
As a kind of preferred version, transition module 3 is formed with a plurality of positioning convex 5 with the end face that feed module 1 and material discharging module 2 join, feed module 1 the be formed with location depression 6 that with the positioning convex 5 of transition module 3 coordinate corresponding to material discharging module 2, transition module like this 3 does not need to align with feed module 1 and material discharging module 2, can link together easily.For convenient docking, positioning convex 5 can be arranged on the two ends of transition passage 31.By the ring flange 4 that is arranged on feed module 1, material discharging module 2, transition module 3 outer rims, the three is fixed together again.
In like manner, the end face that joins at transition module 3 and feed module 1 and material discharging module 2 is formed with a plurality of location depression, feed module 1 and material discharging module 2 are formed with the positioning convex that coordinates with the location depression, having caved in and be arranged on the two ends of transition passage 31 in the location, is also that those skilled in the art can expect.
In the ordinary course of things, feeding-passage 11, transition passage 31, tapping channel 21 are one to one, and feeding-passage 11, transition passage 31, tapping channel 21 join end to end, and make plastic melt can pass through extrusion die.When the plastic melt excess Temperature, feeding-passage 11, tapping channel 21 are one to one, and transition passage 31 can be more than 2 or 2, that one-to-many is corresponding with feeding-passage 11 and tapping channel 21, can extend like this road strength of plastic melt process, make it reach suitable temperature when extruding.
