Abstract
The utility model discloses the coated flexible pipe mould of a kind of high pressure, comprise external mold, core and pvc pipe runner, described core, external mold are separately positioned on institute's pvc pipe runner both sides by from interior and outer order, keep at a certain distance away between described external mold and core and mutually form a PVC stream cavity, the tapered shape in described core leading section and cone angle is 75 °; Adopt the core of large cone angle, shorten PVC stream and lead to distance, just can bear larger pressure and heating-up temperature when producing like this, between the product P VC material produced, adhesion is larger, and it is larger that product is withstand voltage, also booster can not occur, use more convenient safety in using.
Description
Technical field
The utility model belongs to mould tool field, particularly a kind of high pressure cladded type flexible pipe mould.
Background technology
PVC hose is extruded by extrusion die, extrusion die mainly comprises external mold and core, core leading section is tapered, and cone angle is 30 °, low-angle like this taper will form a very long PVC stream cavity, PVC material needs by this longer flowing lumen, the extrusion die of this small-angle can produce PVC hose, but also there is certain defect, the pressure that small-angle mould can bear when producing is little, only have 35 ㎏, and heating-up temperature is also lower, between its PVC of the flexible pipe produced expects, adhesion is little, and then cause the withstand voltage of flexible pipe also to diminish, so long-time use just easily expands or even booster, very large inconvenience is brought to user.
The technical problems to be solved in the utility model is to provide a kind ofly bears the novel die that pressure is large, heating-up temperature is high.
Utility model content
Bear the problems such as pressure is little, heating-up temperature is low for solving above-mentioned prior art, the utility model adopts following technical scheme:
The utility model provides a kind of high pressure coated flexible pipe mould, comprise external mold, core and pvc pipe runner, described core, external mold are separately positioned on institute's pvc pipe runner both sides by from interior and outer order, keep at a certain distance away between described external mold and core and mutually form a PVC stream cavity, the tapered shape in described core leading section and cone angle is 75 °.
The beneficial effects of the utility model are: the core adopting large cone angle, shorten PVC stream and lead to distance, just larger pressure and heating-up temperature can be born during such production, between the product P VC material produced, adhesion is larger, it is larger that product is withstand voltage, also can not there is booster in using, use more convenient safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment in the utility model.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, the coated flexible pipe mould of a kind of high pressure, comprise external mold, core and pvc pipe runner, described core, external mold is separately positioned on institute's pvc pipe runner both sides by from interior and outer order, keep at a certain distance away between described external mold and core and mutually form a PVC stream cavity, the tapered shape in described core leading section and cone angle is 75 °, adopt the core of 75 ° of large cone angles, shorten PVC stream and lead to distance, just larger pressure and heating-up temperature can be born during such production, obtain through producing us, by this change, pressure-bearing value from before 35 ㎏ be increased to 100 ㎏, heating-up temperature too increases 40 degrees Celsius, between the product P VC material produced, adhesion is larger, it is larger that product is withstand voltage, also booster can not be there is in using, use more convenient safety, and the tapered and cone angle in traditional extrusion die core leading section to be only be 30 °, low-angle like this taper will form a very long PVC stream cavity, PVC material needs by this longer flowing lumen, the extrusion die of this small-angle can produce PVC hose, but also there is certain defect, the pressure that small-angle mould can bear when producing is little, only have 35 ㎏, and heating-up temperature is also lower, between its PVC of the flexible pipe produced expects, adhesion is little, and then cause the withstand voltage of flexible pipe also to diminish, so long-time use just easily expands or even booster, very large inconvenience is brought to user, can be addressed these problems by above-mentioned improvement.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
