Abstract
The invention discloses a variable-diameter extrusion die which comprises a basic shell and multiple movable cores. The basic shell is of a cylindrical structure. The tail end of the basic shell is recessed inwards to form a storage groove. The movable cores are arranged at the front end of the basic shell. Multiple first conic holes corresponding to the movable cores are formed in the bottom end of the storage groove. Second conic holes corresponding to the first conic holes are formed in the tail ends of the movable cores. In this way, by the adoption of the variable-diameter extrusion die, the movable cores of different straight discharging hole diameters are replaced so that different plastic strips can be extruded and produced, the plastic strips can be conveniently cut into particles, work efficiency is improved, and the cost of the die is reduced.
Description
Technical field
The present invention relates to extrusion die field, particularly relate to a kind of variable diameters extrusion die.
Background technology
In the extruding of plastic pellet is produced, need to use extrusion die, first plastic raw materials hot melt in barrel, then it is rectangular to obtain plastic cement by the extruded hole on extrusion die, cuts into particle finally by cutting knife rectangular for plastic cement.
In order to obtain the plastic pellet of uniform diameter, the extruded hole on extrusion die requires that diameter will be unified, when changing the diameter of plastic pellet, need the extrusion die changing different model, cost is large, and replacing extrusion die will be cleared up inside, length consuming time, is unfavorable for quick production.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of variable diameters extrusion die, shortens the time of mould conversion particle diameter, reduces costs.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of variable diameters extrusion die, comprise: base house and several movable core body, described base house is cylindrical structural, the end concave of described base house is provided with a stock chest, described movable core body is separately positioned on the front end of base house, the bottom of described stock chest arranges several the first corresponding with movable core body respectively bellmouth, and the end of described movable core body is provided with second bellmouth corresponding with the first bellmouth.
In a preferred embodiment of the present invention, described movable core body front end is provided with the discharging straight hole extending to the second bellmouth.
In a preferred embodiment of the present invention, described slide core end of body is provided with external screw thread, and described base house front end is provided with the screwed hole corresponding with external screw thread.
In a preferred embodiment of the present invention, between described screwed hole with the first bellmouth, be provided with the through hole that external circle is corresponding with slide core.
In a preferred embodiment of the present invention, the end face of described movable core body is provided with several spanner fixing hole.
The invention has the beneficial effects as follows: a kind of variable diameters extrusion die that the present invention points out, by changing the movable core body of different discharging straight hole diameter, can extrude and produce different plastic strips, conveniently cutting into particle, promote operating efficiency, reduce the cost of mould.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of variable diameters extrusion die one of the present invention preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of variable diameters extrusion die, comprise: base house 1 and several movable core body 2, described base house 1 is cylindrical structural, the end concave of described base house 1 is provided with a stock chest 11, described movable core body 2 is separately positioned on the front end of base house 1, the bottom of described stock chest 11 arranges several the first corresponding with movable core body 2 respectively bellmouth 12, and the end of described movable core body 2 is provided with second bellmouth 23 corresponding with the first bellmouth 12.The plastics of hot melt overstock in stock chest 11, and flow into the second bellmouth 23 by the first bellmouth 12, and connecting is good.
Described movable core body 2 front end is provided with the discharging straight hole 21 extending to the second bellmouth 23.Plastics in second bellmouth 23 flow out through discharging straight hole 21, and cool slivering, under the effect of cutting knife, become particle of uniform size.
Described movable core body 2 end is provided with external screw thread, and described base house 1 front end is provided with the screwed hole 13 corresponding with external screw thread, is coordinated with externally threaded by screwed hole 13, and movable core body 2 is fixed in screwed hole 13, and sound construction, not easily gets loose.
Be provided with the through hole corresponding with movable core body 2 cylindrical between described screwed hole 13 with the first bellmouth 12, avoid rocking of movable core body 2, good stability.
The end face of described movable core body 2 is provided with several spanner fixing hole 22, utilize spanner fixing hole 22, with spanner, movable core body 2 can be back-outed, change the movable core body 2 of different discharging straight hole 21 diameter, obtain the particle of different size, the speed changed is fast, and the connecting of production is good, lowers energy consumption and cost.
In sum, a kind of variable diameters extrusion die that the present invention points out, can change the diameter of the particle of production, improving production efficiency fast, reduces the replacement cost of mould.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
