Abstract

The utility model relates to a die holder for plastic line pipes and slots, which has eight die heads and mainly comprises a die holder body 1 and die heads 2, wherein the number of the die heads 2 is eight, and eight die heads 2 are installed on the die holder body 1 in the form of in-line arrangement. The die holder body 1 is provided therein with front flow passages 3, a main flow passage 4, sub flow passages 5 and branch flow passages 6, which are communicated with each other in the order of the front flow passages 3, the main flow passage 4, the sub flow passage 5 and the branch flow passage 6, wherein all the front flow passages 3 with equal length are arranged on the front end of the die holder body 1 and the ends of the main flow passage 4 are connected with two sub flow passages 5. The center line of the main flow passage 4 has equal distances to the ends of two sub flow passages 5. The ends of each sub flow passage 5 are connected with two branch flow passages 6. The central lines of the sub flow passages 5 have equal distances to the ends of two branch flow passages 6. The branch flow passages 6 are communicated with die heads 2. Compared with the prior technology, the utility model has the advantages of convenient operation, high production efficiency, low labor intensity, good security, and high product uniformity and the like, and furthermore as the limitation of the arrangement position is overcome, not only round line pipes can be produced, but also square slots can be produced.

Description

A kind of plastic cord line of rabbet joint pipe die seat with 8 die heads

Technical field:

The utility model relates to a kind of plastic cord line of rabbet joint pipe die seat with 8 die heads.

Background technology:

Production is used for the plastics spool of interior decoration, it mostly is the mode that adopts extrusion molding, normally adopted a supporting extrusion die of extruder (being die head) in the past, afterwards, someone loads onto a die holder on extruder, on this die holder pedestal, mix four die heads, make production efficiency become several times of raisings, when on above-mentioned die holder pedestal, die head being installed, these four die heads must be the square diagonal angle and distribute, so that equal in length from the runner of die holder pedestal front end convey materials to four die head, can make the extrusion pressure on each die head be able to unanimity like this, but, owing to must often adjust the uniformity of extruding spool tube wall thickness in production process, out-of-roundness, and these adjust nuts be distributed in each die head around, operating certain is between four die heads, during the adjustment nut of central area, will be subjected to other die heads and extrude the obstruction of spool, very inconvenient, the adjustment time is longer, when adjusting especially in process of production, operator's phenomenon takes place to scald through regular meeting, in addition, because the restriction of arrangement position, this die holder can only be produced circular spool, can't carry out the production of square wire casing; Also the someone wants to arrange the mode of die head to overcome the deficiency of above-mentioned technology with I-shaped, but because being uneven in length of the runner that arrives edge die head from the die holder front end and the runner that arrives the most central die head, make the extrusion pressure difference of each die head, influence consistency of product, thereby can't implement this imagination.

Summary of the invention:

The purpose of this utility model provides a kind of plastic cord line of rabbet joint pipe die seat with 8 die heads, and it can overcome the deficiencies in the prior art.

The utility model is achieved in that it is mainly by die holder pedestal 1, die head 2 is formed, wherein, the quantity of die head 2 is 8, each die head 2 is contained on the die holder pedestal 1 with the in-line arrangement mode, has preceding runner 3 in the die holder pedestal 1, sprue 4, runner 5 and branch flow passage 6, and by preceding runner 3, sprue 4, runner 5, the order of branch flow passage 6 is communicated with, preceding runner 3 is in the front end of die holder pedestal 1, the equal in length of runner 3 before each, the end of sprue 4 connects two runners 5, the distance of the end of the center line to two of sprue 4 runner 5 equates, the end of every runner 5 connects two branch flow passages 6, the distance of the end of the center line to two of runner 5 branch flow passage 6 equates that branch flow passage 6 is communicated with die head 2.

The utility model passes through the ingenious design to the runner of convey materials, solved the problem of die head extrusion pressure balance, realized the I-shaped arrangement of 8 die heads, a multimode interactional phenomenon when having avoided operation, compared with prior art, have easy to operate, production efficiency is high, labour intensity is low, security is good, the homogeneity of product advantages of higher, and owing to overcome the restriction of arrangement position, not only can carry out circular spool production, can also carry out the production of square wire casing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model

The specific embodiment:

As shown in Figure 1, the utility model is mainly by die holder pedestal 1, die head 2 is formed, wherein, the quantity of die head 2 is 8, each die head 2 is contained on the die holder pedestal 1 with the in-line arrangement mode, has preceding runner 3 in the die holder pedestal 1, sprue 4, runner 5 and branch flow passage 6, and by preceding runner 3, sprue 4, runner 5, the order of branch flow passage 6 is communicated with, preceding runner 3 is in the front end of die holder pedestal 1, the equal in length of runner 3 before each, the end of sprue 4 connects two runners 5, the distance of the end of the center line to two of sprue 4 runner 5 equates, the end of every runner 5 connects two branch flow passages 6, and the distance of the end of the center line to two of runner 5 branch flow passage 6 equates that branch flow passage 6 is communicated with die head 2.

During work, material enters preceding runner 3 from the front end of die holder pedestal 1, enters die head 2 through sprue 4, runner 5, branch flow passage 6, and extrusion molding because it is identical to arrive the material pressure of each die head 2, makes formed product have higher uniformity then; And, when needing to adjust the uniformity, the out-of-roundness of extruded product thickness in process of production, can not be subjected to the influence of other die heads 2 and extruded product thereof because each die head 2 is I-shaped and arranges.
