Abstract
The utility model discloses a kind of extrusion die, comprise die body and air cooling mechanism, be provided with two air channels in described die body, described air cooling mechanism is connected with air channel, and described air channel is folding shape structure in die body, plug, accommodation space and securing member is provided with in described die body, plug position is close in described air channel, and described plug, accommodation space are connected successively with securing member, and described plug is held in die body, described securing member lock onto on die body, has the through hole be interconnected between described plug and securing member; This extrusion die cost is lower, rational in infrastructure, can enhance productivity, and reduce scrappage.
Description
Technical field
The utility model relates to a kind of extrusion die.
Background technology
At present, domestic tubing is all shaping by extrusion die, Vacuum shaping, spraying box cooling forming.But time plastic melt flows out mould, the temperature of plastic melt is very high, when entering vacuum tank sizing, the temperature on water-cooled just surface, the temperature of inside pipe wall is that cooling is inadequate at short notice.The linear velocity so just causing tubing does not promote, and limits the output of finished product.And need to cool step by step due to the temperature of pipe material inner wall, need to increase spraying box, add the cost of equipment.Visible, the extrusion die of this structure, cause manufacturer's cost of idleness, production efficiency is low.
Existing mould is constructively an entirety, often occurs damaging, and can only scrap after damaging after repeatedly using.And the expense of processing a mould is often in unit up to a hundred, process time is longer, and directly increasing manufacturing cost also affects production efficiency.
Summary of the invention
It is lower that the technical problems to be solved in the utility model is to provide a kind of cost, rational in infrastructure, can enhance productivity, and reduce the extrusion die of scrappage.
For solving the problem, the utility model adopts following technical scheme:
A kind of extrusion die, comprise die body and air cooling mechanism, two air channels are provided with in described die body, described air cooling mechanism is connected with air channel, effectively guarantee to cool fast, improve cooling effectiveness, described air channel is folding shape structure in die body, plug is provided with in described die body, accommodation space and securing member, plug position is close in described air channel, described plug, accommodation space is connected successively with securing member, described plug is held in die body, described securing member lock onto on die body, there is between described plug and securing member the through hole be interconnected, through hole can mould the shape of mould.
As preferably, described air cooling mechanism is air exhauster, and cooling is suitable for efficient.
As preferably, the other end that described plug and die body hold gives prominence to die body outside, makes blanking convenient.
As preferably, described securing member is set bolt, and fixed effect is good.
Cold wind mechanism of the present utility model can accelerate the cooling effect of material in mould, enhances productivity, and the design of through hole can reduce scrappage.
The beneficial effects of the utility model are: owing to being provided with air cooling mechanism and air channel, air channel and plug position are close to simultaneously, can be good at the temperature by air-cooled reduction mandrel segment, very convenient, namely cost has been saved, turn increase efficiency, owing to being provided with plug, accommodation space and securing member, mould can be carried out split structure, thus avoid when burn failure, all there is the situation of scrapping in whole mould, has saved cost, too increased production efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is the plane of a kind of extrusion die of the utility model.
Detailed description of the invention
Consult shown in Fig. 1, a kind of extrusion die, comprise die body 1 and air cooling mechanism 2, two projections are had outside described die body 1, facilitate the use of taking of extrusion die, two air channels 3 are provided with in described die body 1, described two air channels 3 are symmetric the top and the bottom in die body 1, described air cooling mechanism 2 is connected with air channel 3, the aperture be communicated with keeps cooling requirement, described air channel 3 is folding shape structure in die body 1, the aeration volume in effective maintenance air channel 3, raise the efficiency, plug 4 is provided with in described die body 1, accommodation space 5 and securing member 6, idle space 5 is parts of die forming, plug 4 position is close in described air channel 3, described plug 4, accommodation space 5 is connected successively with securing member 6, and the axle center of each parts is on same straight line when connecting, described plug 4 is held in die body 1, the radius of described plug 4 is much smaller than the size of accommodation space 5, described securing member 6 lock onto on die body 1, there is between described plug 4 and securing member 6 through hole 7 be interconnected, keep the fastening effect of securing member 6.
Described air cooling mechanism 2 is air exhauster, can change other cold wind mechanism according to the actual requirements.
The other end that described plug 4 and die body 1 hold gives prominence to die body outside, can determine the length of stretching out by actual requirement.
Described securing member 6 is set bolt.
In use, when extrusion die inside has supplied materials to need cold going, the object reaching fast cooling by cold wind mechanism 2, has the through hole 7 be interconnected and effectively can ensure that scrappage when extruding reduces between plug 4 and securing member 6.
The beneficial effects of the utility model are: owing to being provided with air cooling mechanism and air channel, air channel and plug position are close to simultaneously, can be good at the temperature by air-cooled reduction mandrel segment, very convenient, namely cost has been saved, turn increase efficiency, owing to being provided with plug, accommodation space and securing member, mould can be carried out split structure, thus avoid when burn failure, all there is the situation of scrapping in whole mould, has saved cost, too increased production efficiency simultaneously.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
