Abstract

The utility model discloses a two-cavity double-color strip die head which comprises a die sleeve, a discharging die core, an outer-layer shunting core rod, an inner-layer shunting core rod, and an adjusting bolt, wherein an end part of the die sleeve is provided with a discharging die sleeve, the die sleeve is provided with the discharging die core, a discharging channel is arranged between the discharging die sleeve and the discharging die core, the outer-layer shunting core rod comprises an outer-layer charging inlet and shunting channels which are a shunting structure composed of an inclined shunting device, and the inner-layer shunting core rod comprises an inner-layer charging inlet, shunting cores, two oblique shunting grooves, a spiral shunting groove and an annular direct flowing groove, the two oblique shunting grooves being communicated with the spiral shunting groove, the spiral shunting groove being communicated with the annular direct flowing groove and the number of the shunting cores being 14. By employing the above way, the two-cavity double-color strip die head enables the 14 lines to be consistent in forming speed, width and uniformity of tube blanks, thoroughly eliminates interflow traces of the materials, and has advantages of compact structure, stable quality of produced plastic products and reduced processing cost.

Description

A kind of one goes out two two-tone stripe die heads

Technical field

The utility model relates to the plastic molding equipment technical field, particularly relate to a kind of one and go out two two-tone stripe die heads.

Background technology

The die head of tradition blow moulding machine, its structure comprises: die sleeve and the core rod that is arranged in the die sleeve, this core rod is a plug, usually is provided with the flow path groove of center pan feeding formula structure or side feeding structure on the plug, thereby forms runner between plug and die sleeve.The blow moulding machine that is provided with this die head can only be produced the plastic products of individual layer; In actual production process, raw material is along above-mentioned flow passage, and joins at the plotted point of runner, so just can zygonema occur understanding by the product after extrusion modling.Total institute is known, and the speed and the width thereof that form 14 lines are difficult to be consistent, and the uniformity of its formation also is difficult to be consistent, and product is very easy to seepage at meeting zygonema place, thereby has formed substandard product.So both affect the qualification rate of product, increased again manufacturing cost.

The utility model content

The technical problem that the utility model mainly solves provides a kind of one and goes out two two-tone stripe die heads, can guarantee that the uniformity of 14 lines formation speed, width, pipes formation is all consistent, thoroughly eliminates the interflow vestige of material.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of one to go out two two-tone stripe die heads, comprise die sleeve, discharging core rod, outer shunting plug, internal layer shunting plug, adjusting bolt, the end of die sleeve is provided with the discharging die sleeve, be provided with the discharging core rod in the die sleeve, be provided with the discharging runner between described discharging core rod and the discharging die sleeve, described outer shunting plug comprises outer feeding mouth and flow manifold, and described flow manifold is the shunting structure with the part flow arrangement formation of gradient; Described internal layer shunting plug comprises internal layer feed well, shunting core, two oblique splitter boxs, helical shunt groove and ring-type direct current grooves, described two oblique splitter boxs communicate with the helical shunt groove, described helical shunt groove communicates with the ring-type direct current groove, and described shunting core is 14.

The beneficial effects of the utility model are:

1, the utility model by with outer shunting charging with the internal layer side spiral charging be combined, can allow two kinds of raw materials spread uniformly again not phase counterdiffusion, the speed of having guaranteed lines formation is consistent with the uniformity of width and pipe formation, thoroughly eliminate the interflow vestige of material, the plasthetics stay in grade that obtains has also reduced manufacturing cost;

2, by 14 shunting cores, can produce the plasthetics with 14 lines, and between two kinds of color homogeneous phases.

Description of drawings

Fig. 1 is the perspective view that the utility model a kind of goes out two two-tone stripe die heads;

Fig. 2 be shown in the sectional structure schematic diagram of outer shunting plug;

Fig. 3 be shown in the sectional structure schematic diagram of internal layer shunting plug;

The mark of each parts is as follows in the accompanying drawing: 1, die sleeve 2, discharging core rod 3, outer shunting plug 31, outer feeding mouth 32, flow manifold 4, internal layer shunting plug 41, shunting feed chute 42, internal layer feed well 43, shunting core 44, oblique splitter box 45, helical shunt groove 46, ring-type direct current groove 5, adjusting bolt

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

See also Fig. 1 to Fig. 3, the utility model embodiment comprises: die sleeve 1, discharging core rod 2, outer shunting plug 3, internal layer shunting plug 4, adjusting bolt 5, the end of die sleeve 1 is provided with the discharging die sleeve, be provided with discharging core rod 2 in the die sleeve 1, be provided with the discharging runner between described discharging core rod 2 and the discharging die sleeve, described outer shunting core 3 rods comprise outer feeding mouth 31 and flow manifold 32, the shunting structure that described flow manifold 32 consists of for the part flow arrangement with gradient; Described internal layer shunting plug 4 comprises internal layer feed well 42, shunting core 43, two oblique splitter boxs 44, helical shunt groove 45 and ring-type direct current grooves 46, described two oblique splitter boxs 44 communicate with helical shunt groove 45, described helical shunt groove 45 communicates with ring-type direct current groove 46, and described shunting core 43 is 14.

In outer feeding mouth 31 and internal layer feed well 42, adopt as required the raw material of different colours such as Fig. 1, after the raw material of outer feeding mouth 31 is shunted via flow manifold 32, entering 14 shunting cores 43 by shunting feed chute 41 again shunts, the raw material of the raw material after the shunting and internal layer feed well 42 is under the traction of helical shunt groove 45, generation is with an amount of rotatablely moving, two kinds of raw materials are under the lengthwise movement of taking advantage of a situation and the acting in conjunction that rotatablely moves, distribute more evenly, also thoroughly eliminated the interflow vestige.This combination with outer shunting charging and the spiral charging in internal layer side, can allow two kinds of raw materials spread uniformly again not phase counterdiffusion, the uniformity of guaranteeing 14 lines formation speed, width, pipes formation is all consistent, and the plasthetics stay in grade that obtains has also reduced manufacturing cost.

Such as Fig. 3, by 14 shunting cores 43, can produce the plasthetics with 14 lines, and between two kinds of color homogeneous phases.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
