Abstract
The utility model relates to an extruder which comprises a hopper and an extrusion die. An extrusion screw rod is arranged in the hopper. The extrusion die is arranged on one end of the hopper and is connected with a discharging pipeline. The extrusion die comprises an outer die, a mold core and a die face plate. The outer die is provided with a cone-shaped groove. The mold core is arranged in the cone-shaped groove. The die face plates are fixed on the outer sides of the outer die and the mold core so that the outer die and the mold core are integrated. A plurality of channels are arranged on the outer surface of the mold core and used for passing of extrudates. Die openings are arranged in the die face plate and correspond to the channels. The extruder is simple in structure, can be used for simultaneously extruding a plurality of strands of extrudates, and is stable in performance and adjustable in speed.
Description
Technical field
The utility model relates to the extrusion forming device technical field, especially relates to a kind of extruder.
Background technology
Conventional extruder partly is comprised of motor, electrical machine belt pulley, V belt, reductor belt wheel, reductor, hopper, electric appliance control box etc.Plastic extruder is that plastic raw materials is extruded formed in mould machine by the screw rod rotation after heating.The rotation of screw rod in barrel produces extrudes thrust, can become fused solution to plastic raw materials by solid, and plastic raw materials is compressed in screw rod, mix, finally pass through mould molding after, become qualified part or utensil.Traditional plastic extruder is owing to the impact of the factors such as variations in temperature, screw clearance size, and under continuous duty, extrusion capacity is not equivalent.Thereby, the finished commodities after the moulding can produce because of the variation of extrusion capacity raise different.Along with the progress and development of society, all trades and professions are more and more higher to the requirement of product quality, for satisfying user's demand, must reach the consistent of extrusion capacity.
Therefore, a kind ofly can extrude simultaneously the identical extrudate of multiply, the appearance of the extruder of stable performance is necessary.
The utility model content
The utility model is to provide a kind of and can extrudes simultaneously the identical extrudate of multiply, the extruder of stable performance for solving the problems of the technologies described above.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of extruder comprises hopper and extrusion die, in described hopper extrusion screw rod is set, and described extrusion die is arranged at an end of described hopper, and is connected by the discharging pipeline; Wherein, described extrusion die comprises outer mold, core rod and mold panel, described outer mold is provided with conical socket, described core rod is arranged in the described conical socket, and described mold panel is fixed in described outer mold and the core rod outside, makes described outer mold and core rod become an integral body, outer surface at described core rod is distributed with numerous passages, be used for passing through of extrudate, also be provided with die hole on described mold panel, described die hole is corresponding with described passage.
As preferred technical scheme, described extrusion screw rod is twin-screw.
As preferred technical scheme, on described extrusion die, also be provided with flow regulator, described flow regulator is connected with screwed hole on being arranged at described outer mold, and stretch in the described passage, by regulating the degree of depth of described flow regulator in described passage, to arrive pressure and the speed of regulating extrudate.
As preferred technical scheme, described flow regulator is bolt.
The beneficial effect that the utlity model has is:
Simple in structure, can extrude simultaneously the multiply extrudate, stable performance, speed is adjustable.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model: a kind of structural representation of extruder;
Wherein: 1-hopper, 2-extrusion die, 3-extrusion screw rod, 4-discharging pipeline, 5-outer mold, 6-core rod, 7-mold panel, 8-conical socket, 9-passage, 10-die hole, 11-flow regulator.
The specific embodiment
The below will be clearly and completely described the technical scheme among the utility model embodiment, and obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to shown in Figure 1, a kind of extruder comprises hopper 1 and extrusion die 2 and extrusion screw rod 3, and extrusion die 2 is arranged at an end of hopper 1, and is connected by discharging pipeline 4, and extrusion screw rod 3 is arranged in the hopper 1.Extrusion die 2 comprises outer mold 5, core rod 6 and mold panel 7, outer mold 5 is provided with conical socket 8, core rod 6 is arranged in the conical socket 8, mold panel 7 is fixed in outer mold 5 and core rod 6 outsides, make outer mold 5 and core rod 6 become an integral body, be distributed with numerous passages 9 at the outer surface of core rod 6, be used for passing through of extrudate, also be provided with die hole 10 on mold panel 7, die hole 10 is corresponding with passage 9.Extrusion screw rod 3 can be single screw rod or twin-screw, chooses extrusion screw rod 3 in the present embodiment and is twin-screw.
For pressure and speed the utility model of regulating extrudate also proposed another kind of improvement project, be provided with flow regulator 11 at extrusion die 2, flow regulator 11 is bolt, but be not limited to bolt, and be connected with the screwed hole on being arranged at outer mold 5, and stretch in the passage 9, by the degree of depth of adjust flux adjusting device 11 in passage 9, to arrive pressure and the speed of regulating extrudate.
The utility model is a plurality of for the passages 9 by extrudate owing to the outer surface at core rod 6 is provided with, extrudate front end at core rod 6 after passing discharging pipeline 4 branches in each passage 9, by the degree of depth of adjust flux adjusting device 11 in passage 9, can reach the pressure of extrudate and the control of speed, easy to use.
The above only is 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., all should be included within the protection domain of the present utility model.
