Abstract
The utility model discloses a forming plate of an extrusion die head. A cavity is formed in the middle of the forming plate; the left side and the right side of the cavity are parallel; grooves are formed in the positions, located on the outer sides of the left end and the right end of the cavity, on an outlet end surface of the forming plate respectively; and a resistance wire is arranged in each groove and electrically connected with an external power source. According to the forming plate of the extrusion die head, the left surface and the right surface of the cavity are heated by the resistance wires, so that a profile on the forming plate is further heated by the resistance wires when leaving the cavity and the surface brightness of the profile is enhanced.
Description
Technical field
The utility model relates to die head, refers to especially a kind of profiled sheeting of extrusion die.
Background technology
In extrusion molding apparatus, conventionally by die head, be connected with extruder, raw material is heated by extruding machine barrel, screw rod is expressed into die head spreader by plastic melt and distributes, when plastic melt arrives the profiled sheeting of die head, can begin to take shape the basic configuration of wanted article shaped, then leave die head and enter into the stock mould finished product of shaping.The section bar that existing die head is made usually surface brightness is good and affect the attractive in appearance of product, has much room for improvement.
Utility model content
The utility model proposes a kind of profiled sheeting of extrusion die, solved the not good problem of Surface of profile brightness.
The technical solution of the utility model is achieved in that
A kind of profiled sheeting of extrusion die, its middle part is provided with a die cavity, and the left and right sides of this die cavity is parallel, on the exit end face of described profiled sheeting, in die cavity the right and left end outside, is respectively equipped with a groove, in described groove, be respectively equipped with a resistance wire, described resistance wire is electrically connected to external power source.
Preferred version is that each groove is parallel with the outside of die cavity, and spacing is 2-4mm.
Preferred version is that described profiled sheeting is respectively equipped with a heat dam in each groove outside.
Preferred version is that the periphery in die cavity on described profiled sheeting is provided with a plurality of feed orifice.
Preferred version is between described resistance wire and external power source, to be connected with an attemperating unit.
Preferred version is that each groove extends to the bight near profiled sheeting along clockwise direction by the outside of die cavity.
Preferred version is that the arrival end of described profiled sheeting is provided with an accepting groove in the corner positions of the profiled sheeting at notch end place, is provided with the plug being connected with resistance wire in this accepting groove.
The beneficial effects of the utility model are:
The profiled sheeting of extrusion die in the utility model, heats surface, die cavity left and right by resistance wire, so that the section bar on profiled sheeting further heats by this resistance wire when leaving this die cavity, thus reinforcing profile surface brightness.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the exit end face schematic diagram of the utility model profiled sheeting one preferred embodiment.
In figure:
10, die cavity; 20, groove; 30, accepting groove; 40, resistance wire; 50, plug; 60, heat dam; 70, feed orifice.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the profiled sheeting of the extrusion die of the present embodiment, its middle part has a die cavity 10, the right and left almost parallel of this die cavity 10.On the exit end face of described profiled sheeting, in die cavity 10 the right and left end outsides, be respectively equipped with a groove 20, described groove 20 is parallel with the outside of die cavity 10, and spacing is 2-4mm.Each groove 20 extends to the bight near profiled sheeting along clockwise direction by the outside of die cavity 10.The arrival end of described profiled sheeting is provided with an accepting groove 30 in the corner positions of the profiled sheeting at groove 20 end places.In described groove, 20 are respectively equipped with a resistance wire 40, in described accepting groove 30, be provided with the plug 50 being electrically connected to resistance wire 40, by these plug 50 external power supplys so that this resistance wire 40 produces heats, by 40 pairs of die cavities of this resistance wire, 10 surfaces, left and right, heat, so that the section bar on profiled sheeting further heats by this resistance wire 40 when leaving this die cavity 10, thereby reinforcing profile surface brightness.Control to described groove 20 with die cavity 10 spacing, can prevent the too high or too low for temperature of 40 pairs of section bar heating of resistance wire, to reach optimum efficiency.Described plug 50 also can be electrically connected to external power source by an attemperating unit, thus the heating-up temperature of better controlling resistance silk 40.
Described profiled sheeting is provided with a heat dam 60 in groove 20 outsides, thereby prevents other parts of die head to be heated and influenced.Periphery in die cavity 10 on described profiled sheeting is provided with a plurality of feed orifice 70, can be to the independent feed of die cavity 10 on this profiled sheeting, and prevent under feeding in this region or too much affect end properties.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
