Abstract
The utility model relates to a basket type outer sheath pipe mold, which comprises, a molding body, a straight-flow body, a spiral body, a flow-dividing body and a feed body forming a pyramidal structure from bottom to top, wherein the middle of the feed body is provided with a feed port, the lower end of the feed port is provided with a flow-dividing pipe, the flow-dividing pipe is connected with a spiral pipe in the spiral body, the spiral pipe has outward-extending splayed structure, the lower port of the spiral pipe is connected with a straight-flow pipe in the straight-flow body, the lower port of the straight-flow pipe is connected with a vertical molding pipe in the molding body, and the molding pipe, the straight-flow pipe, the spiral pipe and the flow-dividing pipe form a basket type pyramidal structure from bottom to top. In the basket type outer sheath pipe mold provided by the utility model, by substituting spiral flow generated in the basket type pyramidal structure in the mold for original straight flow, the allowable pressure is increased, the extrusion molding can realize continuous and automatic production, the produced high density polyethylene outer sheath pipe wall thickness is uniform, and stretching rate and breaking elongation rate can be improved, the product performance is stable, and the raw material consumption, energy consumption and labor cost are reduced.
Description
Technical field
The utility model relates to a kind of basket oversheath pipe mold.
Background technology
Along with the prefabricated direct-buried thermal insulation pipe road is used in northern China Winter heat supply area, the production technology and the industry size of the outer pillar of high density polyethylene (HDPE) obtain develop rapidly.The traditional moulds of the production process use of the outer pillar of high density polyethylene (HDPE) is the shunting support at present, and the charging aperture of this support has only one deck screen cloth, and raw material plasticizing back joins in traction tube after extruder flows out to divide streamed entering extruder, directly draws.Mainly there is following problem in the outer pillar of the high density polyethylene (HDPE) that uses traditional moulds to produce: the outer pillar wall unevenness of polyethylene is even, and extensibility is low, and compression strength is not up to standard, and overall performance is poor.
Summary of the invention
The utility model provides a kind of wall thickness that makes even for solving the technical problem that exists, and can improve the basket oversheath pipe mold of high density polyethylene (HDPE) of overall performance.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of basket oversheath pipe mold; Comprise the pan feeding body, divide fluid, straight fluid and formed body; Be provided with conveyor screw, said formed body, straight fluid, conveyor screw, branch fluid and pan feeding body between said minute fluid and the straight fluid according to down and go up and form pyramidal structure; Said pan feeding body middle part is provided with feeding mouth, and the lower port of said feeding mouth is provided with isocon, the helix tube interface in said isocon and the conveyor screw; Said helix tube is the outer splayed structure of casting aside; Vertical forming interface tube in the DC tube interface in said helix tube lower port and the straight fluid, said DC tube lower port and formed body, said moulding pipe, DC tube, helix tube and isocon become basket pyramidal structure on according to descending.
The utility model can also adopt following technical measures:
Said formed body bottom is a base, and said base is provided with installing hole.
Said helix tube includes extra heavy pipe, herringbone pipe and the vertical tube that connects successively from top to down, and the diameter of said extra heavy pipe is greater than the diameter of all the other pipes.
Said DC tube comprises outer inclined tube and straight tube from top to down.
Advantage and the good effect that the utlity model has are: the utility model replaces traditional shunting support rack type mould to produce high density polyethylene (HDPE) oversheath pipe with novel basket netted mould; The helical flow that makes this basket network structure produce has replaced original streamlined flow; Press thereby increased to hold; Extrusion molding can realize serialization, automated production, and the outer pillar wall thickness of the high density polyethylene (HDPE) of producing is even, and extensibility and elongation at break are improved; Properties of product are stable, reduced consumption of raw materials, energy resource consumption and cost of labor.

The specific embodiment
For further understanding utility model content, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of high density oversheath pipe mold comprises pan feeding body 1, divides fluid 2, conveyor screw body 3, straight fluid 4 and formed body 5, formed body 5, straight fluid 4, conveyor screw 3, divide fluid 2 and pan feeding body 1 according to down and on be assembled into pyramidal structure.Pan feeding body 1 middle part is provided with feeding mouth 6; The lower port of feeding mouth 6 is provided with isocon 7; Isocon 7 passes branch fluid 2; With extra heavy pipe 803 interfaces of helix tube 8 in the conveyor screw 3, helix tube 8 integral body are the outer splayed structure of casting aside, and include the extra heavy pipe 803, herringbone pipe 802 and the vertical tube 801 that connect successively from top to down; The diameter of extra heavy pipe 803 is greater than all the other pipes diameter of (comprising isocon 7, herringbone pipe 802, vertical tube 801, DC tube 9, outer inclined tube 901, straight tube 902 and moulding pipe 10); Vertical forming tubes 10 interfaces in outer inclined tube 901 interfaces in DC tube 9 tops in vertical tube 801 lower port of helix tube 8 lower ends and the straight fluid 4, DC tube 9 bottom straight tubes 902 and formed body 5, moulding pipe 10, DC tube 9, helix tube 8 and isocon 7 according under and on become basket pyramidal structure.
Formed body 5 bottoms are base 11, and base 11 is provided with installing hole, through installing hole the mold of different-diameter can be installed, and produce the high density polyethylene (HDPE) oversheath pipe of different size.
The utility model replaces traditional shunting support rack type mould to produce high density polyethylene (HDPE) oversheath pipe with novel basket netted mould; The helical flow that makes this basket network structure produce has replaced original streamlined flow, presses thereby increased to hold, and extrusion molding can realize serialization, automated production; The outer pillar wall thickness of the high density polyethylene (HDPE) of producing is even; Extensibility and elongation at break are improved, and properties of product are stable, reduced consumption of raw materials, energy resource consumption and cost of labor.
