Abstract
The utility model discloses a PVC profiled bar inner-cooling device, which includes a die head (1) and a stock die (2), wherein a cooling rod connecting plate (3) extending to the inside of the stock die is fixedly connected onto the die head; the tail end of the cooling rod connecting plate is fixedly connected with cooling rods (4) filled with cooling liquid and matched with the inside of a stock die cavity. The PVC profiled bar inner-cooling device has the benefits that the entire section bar extruded out from the die head is quickly and uniformly cooled from a high temperature to a low temperature during the entire extrusion through a cooling pipeline and the cooling rods in the stock die cavity; the cooling rods are distributed inside the stock die cavity in a crossed and three-dimensional manner, so as to conduct heat to places where the cooling water cannot reach and comprehensively cool plastic section bars, as a result, the expansion effect of plastic section bars due to too big pressure can be avoided, the cooling manner is simple and the floor space is small.
Description
Technical field
The utility model relates to the mould for plastic extrusion, relates in particular to device for cooling in PVC profile shapes.
Background technology
Stock mould is the size and dimension in order to control special product, a kind of fixture of using when cooling.In extrusion molding process, the Main Function of stock mould, exactly by the molten parison of extruding from die head, through vacuum suction, makes it be close to die cavity table wall.Plastic material is generally raw material obtain certain beginning in extruder barrel through die head molten embryo after fusion plastification, enter into again in shaper, on stock mould, there are vacuum hole and Cooling Holes, plastic material is in the vacuo-forming of mould internal diameter, the logical cold water of Cooling Holes is used for cooling and shaping, the finished product of plastic material is extruded from the mould other end, existing mould is because environment in mould comparatively seals, radiating effect is not good, cooling and shaping effect is bad, therefore must keep aborning slower Negotiation speed, production efficiency is lower.At present, in the stock mould type of cooling, because each die casting producer is in the difference of the various factors such as design concept, stock mould length, process equipment, processing technology, the type of cooling is also not quite similar.The Chinese utility model patent in notification number CN201471717U, May 19 2010 day for announcing discloses a kind of " dry wet combination stock mould " by name, this utility model is placed on two parts by refrigerating function and realizes, Part I is undertaken cooling by the Cooling Holes in stock mould, the open tank of Part II after by stock mould carries out cooling, although obtained good cooling effect, but occupied ground area is larger, and can not be to mould is small but ledge carries out fast because extruding the heat bringing, heat radiation comprehensively.
Utility model content
The technical problems to be solved in the utility model is that existing stock mould cooling device is all to adopt the cooling line of stock mould inside to coordinate external cooling device as open tank, occupied ground area is large, cooling slowly not comprehensive, provide that one saves floor occupying area, cooling device for cooling in PVC profile shapes fast comprehensively for this reason.
The technical solution of the utility model is: device for cooling in PVC profile shapes, it comprises die head and stock mould, it is characterized in that being connected with to the inner cooling stick connecting plate extending of stock mould on described die head, the end of described cooling stick connecting plate is connected with the cooling stick that adapts to the built-in cooling fluid in sizing die cavity.
Cooling stick described in such scheme has 3, and wherein two of horizontal distribution, vertically distribute one.
Cooling fluid described in such scheme in cooling stick is ethylene glycol.
The length of cooling stick described in such scheme is 55-100mm.
The beneficial effects of the utility model are that the section bar that die head is extruded passes through cooling line and the cooling stick in stock mould, make whole section bar cold by thermal change rapidly and uniformly in whole section of extrusion, cooling stick is crossed space and distributes in sizing die cavity, to cooling water stay less than place carry out heat conduction, realization is comprehensively cooling to plastic material, guarantee that plastic material can not produce bulking effect because pressure is excessive, the type of cooling is simple, floor space is few.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
In figure, 1, die head, 2, stock mould, 3, cooling stick connecting plate, 4, cooling stick.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises die head 1 and stock mould 2, is connected with to the inner cooling stick connecting plate 3 extending of stock mould on described die head, and the end of described cooling stick connecting plate is connected with the cooling stick 4 that adapts to the built-in cooling fluid in sizing die cavity.
In the chamber of stock mould, be provided with Cooling Holes, Cooling Holes is communicated with the cooling water pipe in one end external world, and the other end is communicated with the cooling line in chamber, and cooling stick fits in chamber, its material can be copper shell, cooling fluid is equipped with in inside, and cooling fluid is preferably ethylene glycol, good cooling results, cooling stick is not only by metal conduction heat, and be that cold-producing medium is used as heat-exchange medium, heat conductivity is 200 times of copper, and has good thermo-responsive.Length can be 55-100mm, and preferred length is the smaller the better, and length is less, more can to cooling water in cooling line stay less than place carry out cooling.
Cooling stick can have 3, wherein two horizontal distribution, and another vertically distributes, and has formed three-dimensional cooling system like this in sizing die cavity, and the omnibearing plastic material to process is cooling, can be also two and vertically distribute, another horizontal distribution.
When installation, cooling stick is inserted to stock mould inside cold in carrying out comprehensively to section bar, then by water tank, shaping platform, hauling machine and cutting machine, thus section bar obtains being as cold as in continuous the process of moulding.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
