Abstract
The utility model relates to a plastic profile extrusion die. The plastic profile extrusion die comprises a die assembly and a heating rod, wherein the heating rod is radially installed on the die assembly; the die assembly is formed by coaxially connecting a plurality of discs; a plurality of inserts are coaxially inlaid on the outer edge wall of a cavity of a second-section disc. The plastic profile extrusion die has the advantages and positive effects that by inlaying a plurality of inserts on the wall of the cavity, the extrusion flow velocity can be effectively adjusted, the die cost is greatly reduced, and the extrusion die is flexible and convenient to use; an insulating layer is installed to coat the edge of the extrusion die so as to play a role of insulating, thus effectively ensuring the extrusion velocity and the profile quality and saving the energy; the plastic profile extrusion die is scientific and reasonable in design, has a simple structure, is easy to achieve and effectively ensures the profile quality.
Description
Technical field
The utility model belongs to technical field of mold, specifically, is a kind of plastic profiled bar extrusion die.
Background technology
The production process of plastic irregular profile is: plastic raw materials is sent in the barrel of extruder, and make plastic raw materials conveying, compression, melting, plasticizing between the screw rod of rotation and barrel, then quantitatively by extrusion die and shaper in extrusion machine head, then draw by hauling machine, cut into again the size of appointment through cutting machine, produce thus the machining process of continuous section bar.
Especially profile shapes, its mould structure complexity, causes extruding flow velocity inhomogeneous, thereby affect the quality of plastic irregular profile, therefore trimming die gets up very difficultly, unsuccessfully can only again open a set of new mould if debugged again, and has so improved widely the cost of product; In addition, the heat radiation of extrusion die is very fast, thereby affects extruded velocity and section quality.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of simple in structure, flow velocity adjustment is simple, the plastic profiled bar extrusion die of insulation.
Scheme of the present utility model is achieved in that
A kind of plastic profiled bar extrusion die, comprises die assembly and heating rod, and described heating rod is radially arranged on die assembly, and described die assembly is coaxially formed by connecting by multiple disks, on the chamber perimeter wall of described second segment disk, is coaxially inlaid with multiple inserting.
And, described in the length of inserting be disk length 1/3rd to 1/2nd between.
And the coaxially coated iron sheet layer of the outer rim of described die assembly is installed a heat-insulation layer between iron sheet layer and die assembly outer rim.
Advantage of the present utility model and good effect are:
This mould, by be inlaid with multiple inserting on chamber wall, therefore can effectively regulate and extrude flow velocity, has greatly reduced die cost, flexible and convenient to use; By at the coated heat-insulation layer of installing of its outer rim, therefore play the effect of insulation, effectively guarantee extruded velocity and section quality, and saved the energy.The utility model design science is reasonable, simple in structure, is easy to realize, and has effectively guaranteed section quality.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model (broken section);
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
A kind of plastic profiled bar extrusion die, as shown in Figure 1, comprises die assembly and heating rod 3, and described heating rod is radially arranged on die assembly, and described die assembly is coaxially formed by connecting by multiple disks, is four in the present embodiment accompanying drawing.
Innovative point of the present utility model is:
1, on chamber 5 perimeter walls of described second segment disk 4, be coaxially inlaid with and multiplely insert 6, as shown in Figure 2, each inserting is fixed on second segment disk by chock, this length of inserting be disk length 1/3rd to 1/2nd between.Described quantity of inserting can according to the structure of chamber determine, in the present embodiment accompanying drawing, inserting is four, described in insert outside disk on be shaped with installing hole 7.Insert to realize by finishing and adjust the object of extruding flow, and quick and easy for installation, greatly reduce die cost, and improved the quality of plastic irregular profile.
2, the coaxially coated iron sheet layer 1 of the outer rim of this die assembly is installed a heat-insulation layer 2 between iron sheet layer and die assembly outer rim.The effect of described iron sheet layer is for fixing heat-insulation layer, and for the ease of installing, iron sheet layer links together its both ends by screw, nut, therefore installs, to debug die assembly convenient and swift.
This mould, by be inlaid with multiple inserting on chamber wall, therefore can effectively regulate and extrude flow velocity, has greatly reduced die cost, flexible and convenient to use; By at the coated heat-insulation layer of installing of its outer rim, therefore play the effect of insulation, effectively guarantee extruded velocity and section quality, and saved the energy.The utility model design science is reasonable, simple in structure, is easy to realize, and has effectively guaranteed section quality.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model comprises and is not limited to the embodiment described in the specific embodiment; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
