The mold is internally provided with a forming cavity and comprises a forming plate, a compression plate and a supplying section, wherein the forming plate is arranged at one side of the compression plate, a heat-insulation groove is arranged between the forming plate and the compression plate, and the supplying section is connected at the other side of the compression plate. Compared with the prior art, the plastic profile extrusion mold utilizing the cooling of the circulating water to adjust the extrusion pressure not only can greatly improve the temperature reduction and pressure increasing speed during extrusion process of a profile, and greatly reducing the energy consumption, but also can ensure the plasticizing effect of materials to be unchanged.
Description
Technical field
The utility model relates to a kind of pressure forming mould, especially relates to a kind of plastic profiled bar extrusion die that utilizes the recirculated water cooling to regulate extrusion pressure.
Background technology
Plastic irregular profile has substituted the effect of aluminium alloy and steel in a lot of fields at present, and PVC widely applies and extrudes the field at section bar, and to mould for the steel energy-conserving and environment-protective, plastic irregular profile is decorated field extensive uses such as furniture at building doors and windows.But in actual production, because different extrusion equipments, the difference of formula system and product section can cause the fluctuation of melt pressure in the extrusion to reduce, material fluidity differs greatly, the density of product is not enough, have a strong impact on the extrusion molding of goods, cause the product physical property not up to standard, phenomenons such as cracking.In the production process of extrusion die, several means is arranged, but the temperature that reduces profiled section is the most also to be mode the most efficiently for improving extrusion pressure.Original profiled bar extrusion die all is to adopt large-area heater, there is not the single area branch that the heater of feed section and profiled section is set, only depend on and lower the temperature automatically by heating plate that to increase the mode speed of pressure slow, and transmitted institute's interference effect cooling pressurized effect by the heat of other sections of mould easily, energy consumption is higher.Simultaneously since in the temperature-fall period whole die head be in whole temperature-fall period, the feed section also must passive cooling, has so just had a strong impact on the plasticizing effect of material, has guaranteed that extrusion pressure but can't guarantee the plasticizing of material.
The utility model content
The purpose of this utility model is exactly to provide a kind of in order to overcome the defective that above-mentioned prior art exists and cut down the consumption of energy significantly, improve the recirculated water cooling that utilizes of the speed of cooling supercharging in the section bar extrusion to regulate the plastic profiled bar extrusion die of extrusion pressure.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of plastic profiled bar extrusion die that utilizes the recirculated water cooling to regulate extrusion pressure, molding cavity is set in the mould, this mould comprises profiled sheeting, compressive plate and feed section, described profiled sheeting is located at a side of compressive plate, described feed section is connected the opposite side of compressive plate, and described profiled sheeting top is provided with water inlet, and the bottom is provided with delivery port, inside is provided with the circulation water channel, and described circulation water channel is connected with described delivery port with described water inlet.
Preferably, described circulation water channel is a rectangle structure.
Preferably, the cross section of described profiled sheeting greater than compressive plate and feed section cross section.More preferably, described profiled sheeting is a rectangular structure.
Preferably, offer heat insulation groove between profiled sheeting and the compressive plate.
Preferably, described water inlet is provided with control valve.
Compared with prior art, the utility model can not only increase substantially the speed of cooling supercharging in the section bar extrusion, and cuts down the consumption of energy significantly, has guaranteed also that simultaneously the plasticizing effect of material is constant.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is a left TV structure schematic diagram of the present utility model.
1 is that profiled sheeting, 2 is that compressive plate, 3 is that feed section, 4 is that heat insulation groove, 5 is that circulation water channel, 6 is that water inlet, 7 is that delivery port, 8 is a molding cavity among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of plastic profiled bar extrusion die that utilizes the recirculated water cooling to regulate extrusion pressure, molding cavity 8 is set in the mould, its structure is shown in Fig. 1～2, this mould comprises profiled sheeting 1, compressive plate 2 and feed section 3, profiled sheeting 1 is located at a side of compressive plate 2, offer heat insulation groove 4 between profiled sheeting 1 and the compressive plate 2, reduced the contact-making surface between the plate, significantly reduce the transmission of the heat in mould feed zone to forming area, the top of profiled sheeting 1 is provided with water inlet 6, and the bottom is provided with delivery port 7, inside is provided with circulation water channel 5, circulation water channel 5 is a rectangle structure, and top is connected with the water inlet 6 at profiled sheeting 1 top, and the bottom is connected with the delivery port 7 of profiled sheeting 1 bottom, heat is taken away in circulation by cooling water fast, reduce the flowability of material, improve extrusion pressure, guarantee the density and the molding effect of extruded product.Because cooling rate is fast, has avoided a large amount of meaningless heat transmission again, has significantly reduced power consumption, has improved production efficiency, on the water inlet 6 control valve can also be set, in order to regulate the flow of cooling water.Feed section 3 is connected the opposite side of compressive plate 2.
Common extrusion die is the cuboid or the square of size criteria substantially, only adopts the mode of heating of an integral body, can't regulate the temperature between profiled section and the feed section separately.Profiled sheeting 1 profile that the utility model mould structure adopts strengthens, cross section is greater than compressive plate 2 and feed section 3, can adopt heating plate device separately by profiled sheeting 1 like this, compressive plate 2 and feed section 3 also can adopt independent heating plate device separately, thus the temperature of regulating different sections separately.Water inlet 6 connects cooling water pipes, takes away the heat of profiled sheeting 1 by the circulation water channel 5 of die head inner dotted line part, gets rid of by delivery port 7.In actual production, pass through the temperature of recirculated water fast cooling shaping plate 1, simultaneously significantly reduced heat transmission between two zones owing to be present in heat insulation groove 4 between profiled sheeting 1 and the compressive plate 2, in profiled sheeting 1 quick cooling procedure, compressive plate 2 and feed section 3 are kept the constant of plasticizing heating-up temperature, so promptly guaranteed the stable normal plasticizing effect that guarantees material again of feed section 3 temperature, avoided simultaneously heat transmission again to profiled sheeting 1, make the temperature of moulding flat segments to reduce fast, the extrusion pressure fast rise, guarantee the density and stablizing of extruding of product, the size that control valve adjusting current can be installed at water inlet guarantees to reach the temperature that needs.
