Abstract
The utility model relates to a thin-wall spiral mould, which is provided with a connecting body with one end connected with a main machine head, the other end of the connecting body is connected with one end of a spiral body provided with a spiral body sleeve, the other end of the spiral body sleeve is sequentially connected with a middle mould body, a mould shell and an opening mould, the other end of the spiral body is sequentially connected with a mould core and a core rod which are arranged at the central part of the mould, and a product is extruded from a flow passage of the core; a feed inlet for feeding is formed in the center of the main machine head and the connecting body; a middle connecting rod with an exhaust passage at the central part is arranged in the mold core cavity; a spiral copper bar is arranged outside the middle connecting rod; and an air inlet channel is arranged in the center of the copper bar and is connected with a high-temperature ball valve cooling device arranged on the spiral body. The thin-wall spiral die is uniformly heated, has good material fluidity and has no dead angle; the pressure consumption is low, and the yield is high; the core rod support is not needed, so that the flow lines which often occur in the production disappear; compact structure, reasonable connection and convenient replacement.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of thin-walled spiral mould.
Background technology
At present, there are many moulds to cause product surface rough on the market because of exhaust is bad, and the surperficial phenomenon that obvious seam is arranged, and the product size that this die production is come out is also unstable.Material fluidity is bad, Flow of Goods and Materials has phenomenons such as dead angle because the irrational phenomenon of design causes easily for the conveyor screw head number of mould inside and groove depth; Add that pressure consumption is too much in process of production; Therefore can reduce the output of product, influence company's productivity effect.
Summary of the invention
The utility model technical problem to be solved provides the thin-walled spiral mould that a kind of material fluidity is good, production efficiency is high.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
This thin-walled spiral mould; Has the connector that an end is connected with host header; The connector other end is connected with conveyor screw one end that is provided with the conveyor screw cover; The said conveyor screw cover other end is connected with middle die body, formwork and mouthful mould in turn, and the said conveyor screw other end is connected with core rod and the plug that is arranged on the mold center position in turn, and goods are extruded from the plug and the runner of mouthful mould.
Charging for ease, further, said host header and connector centre are provided with the charging aperture that is used for charging.
For each section of center connected, further, be provided with the middle brace rod of central part bit strip exhaust passage in the said core rod cavity.
For core rod keeps favorable cooling effect, further, said middle brace rod outer setting has helical copper rod.
Further, said copper rod center is provided with inlet channel, and is connected with high-temperature ball valve cooling device on being arranged on conveyor screw.
In order to guarantee that material fusion in mould forms continuous tubing, more further, said mould outer setting has heater.
In order can the conveyor screw cover to be connected with middle die body, further, said conveyor screw cover outer setting is useful on the adpting flange that is connected with middle die body.
Compared with prior art, the usefulness of the utility model is: this thin-walled spiral mould is heated evenly, and material fluidity is good, no dead angle; Pressure consumption is few, and output is high; Need not the plug support, make that the normal flow liner that takes place disappears in the production; Compact conformation connects rationally, and it is convenient to change.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model thin-walled spiral mould internal structure sketch map.
Among the figure: 1, mouthful mould; 2, plug; 3, core rod; 4, middle brace rod; 5, middle die body; 6, conveyor screw; 7, adpting flange; 8, heater; 9, exhaust outlet; 10, copper rod; 11, inlet channel; 12, goods; 13, connector; 14, high-temperature ball valve cooling device; 15, host header; 16, charging aperture; 17, formwork; 18, conveyor screw cover.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:
A kind of thin-walled spiral mould shown in Figure 1; Has the connector 13 that an end is connected with host header 15; Connector 13 other ends are connected with conveyor screw 6 one ends that are provided with conveyor screw cover 18; Said conveyor screw overlaps 18 other ends and is connected with middle die body 5, formwork 17 and mouthful mould 1 in turn, and wherein conveyor screw cover 18 is connected with middle die body 5 through adpting flange 7, and said conveyor screw 6 other ends are connected with the core rod 3 and plug 2 that is arranged on the mold center position in turn; Said host header 1 is provided with the charging aperture 16 that is used for charging with connector 13 centres; The mould outer setting has heater 8, makes the material fusion, and mould is heated evenly, guarantees that materials flow is stable; Be provided with the middle brace rod 4 of central part bit strip exhaust passage 9 in said core rod 3 cavitys; Middle brace rod 4 outer setting have helical copper rod 10; Said copper rod 10 centers are provided with inlet channel 11; And be connected with high-temperature ball valve cooling device 14 on being arranged on conveyor screw 6, make core rod 3 positions have favorable cooling effect.Each parts connects with 12.9 grades of screws, and the face that material is passed through does not have the gap, the material phenomenon can not occur leaking, and fused mass is full of mouthful mould 1 and plug 2 runners gradually through each parts, under extrusion pressure, continues to advance, and processes continuous goods 12.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
