Description
Technical field
The utility model relates to extruding machine equipment field, particularly relates to and a kind ofly improves the extruder system that bellmouth goes out pipe quality.
Background technology
Extruder system is used to the capital equipment producing spigot-and-socket double-wall corrugated pipe, it comprises extruding machine body, be located at the die head of extruding machine body front end, be located at the calibration sleeve of die head front end and be arranged on the external diameter mould of calibration sleeve periphery along calibration sleeve bearing of trend, wherein be provided with inner layer film discharging opening in die head front end, outer membrane discharging opening and the outer gas port be located between inner layer film discharging opening and outer membrane discharging opening, the end face that described die head is connected with calibration sleeve is provided with interior gas port, calibration sleeve is arranged on die head front end, interior gas port is given vent to anger and is just discharged from the gap between calibration sleeve and die head, its workflow is, first make pipe shaft, under the effect of external diameter mould, inner layer film discharging opening, the discharging simultaneously of outer membrane discharging opening, outer gas port is given vent to anger, form double-wall corrugated pipe shaft structure, make bellmouth again, under the effect of external diameter mould, inner layer film discharging opening, the discharging simultaneously of outer membrane discharging opening, outer gas port stops giving vent to anger, interior gas port is from the gap Exhaust Gas between calibration sleeve and die head, molten condition material is under gas pressure, be fitted on external diameter mould, form bellmouth, gap between current calibration sleeve and die head is uneven, cause outgassing direction and tolerance size can not ring week distribution uniformly, affect bellmouth and go out pipe quality.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of and improve the extruder system that bellmouth goes out pipe quality.
The utility model is achieved by the following technical programs:
A kind ofly improve the extruder system that bellmouth goes out pipe quality, comprise extruding machine body, be located at the die head of extruding machine body front end, be located at the calibration sleeve of die head front end and be arranged on the external diameter mould of calibration sleeve periphery along calibration sleeve bearing of trend, be provided with the gas dispersion pad of ring-type between described die head and calibration sleeve, described gas dispersion pad sidewall is provided with gas dispersion hole.
The beneficial effects of the utility model are:
Owing to being provided with the gas dispersion pad of ring-type between described die head and calibration sleeve, described gas dispersion pad sidewall is provided with gas dispersion hole, the gap between calibration sleeve and die head is filled up with gas dispersion pad, make when making bellmouth, the gas dispersion hole of interior gas gas dispersion pad is discharged, outgassing direction and tolerance ring week distribution of uniform size, improve bellmouth and go out pipe quality.

Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is end face structure schematic diagram between die head of the present utility model and calibration sleeve.
Fig. 3 is gas dispersion gasket construction schematic diagram of the present utility model.
In figure: 1. die head, 2. inner layer film discharging opening, 3. outer membrane discharging opening, 4. calibration sleeve, 5. gas dispersion pad, 6. outer gas port, 7. external diameter mould, gas port 8., 9. gas dispersion hole.
Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises extruding machine body, be located at the die head 1 of extruding machine body front end, be located at the calibration sleeve 4 of die head front end and be arranged on the external diameter mould 7 of calibration sleeve periphery along calibration sleeve bearing of trend, be provided with the gas dispersion pad 5 of ring-type between described die head and calibration sleeve, described gas dispersion pad sidewall is provided with gas dispersion hole 9.
During workflow, first make pipe shaft, under the effect of external diameter mould, inner layer film discharging opening, the discharging simultaneously of outer membrane discharging opening, outer gas port 6 is given vent to anger, form double-wall corrugated pipe shaft structure, make bellmouth again, under the effect of external diameter mould, inner layer film discharging opening 2, outer membrane discharging opening 3 discharging simultaneously, outer gas port stops giving vent to anger, interior gas port 8 is from the gap Exhaust Gas between calibration sleeve and die head, molten condition material is under gas pressure, be fitted on external diameter mould, form bellmouth, owing to being provided with the gas dispersion pad of ring-type between described die head and calibration sleeve, described gas dispersion pad sidewall is provided with gas dispersion hole, the gap between calibration sleeve and die head is filled up with gas dispersion pad, make when making bellmouth, the gas dispersion hole of interior gas gas dispersion pad is discharged, outgassing direction and tolerance ring week distribution of uniform size, improve bellmouth and go out pipe quality.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
