Abstract
The utility model discloses an extruding machine head with reducing diameter. The extruding machine head comprises a machine head body, a split-flow shuttle, a mouth die, a core rod and a material channel, wherein the material channel is composed of the machine head body, the split-flow shuttle, the mouth die and the core rod; the core rod consists of a front section, a middle section and a back section; one section close to the machine head body is the front section of the core rod; one section away from the machine head body is the back section of the core rod and is cylindrical; the diameter of the back section of the core rod is greater than that of the front section of the core rod; and the front section of the core rod is gradually transited to the back section of the core rod through the middle section of the core rod. By virtue of the extruding machine head with the reducing diameter, the mouth die and the core rod of the conventional extruding machine head are reasonably improved, and the extruding machine head is suitable for producing pipes with large diameters, so that the preparation stability of the pipes with large sizes is improved, and the pressure-resistant performance and the impact-resistant performance of the pipes are improved.
Description
Technical field
The utility model relates to the extrusion equipment technology, specifically relates to a kind of reducing extruder head.
Background technology
Extruder head has following effect in the production of tubing: 1) make the viscous state material make screw become parallel lines motion, and introducing port mould and being shaped stably; 2) produce back pressure, make the further homogenizing of material, improve quality of item; 3) produce necessary briquetting pressure, with obtain structure closely knit with shape goods accurately.Extruder head generally comprises handpiece body, spreader, mouthful mould and plug four parts.The tubing that is prepared by mouth mould and plug combines different typing modes through the typing cover again, can obtain the tubing of different tube diameters.The head of existing producer design, normally head satisfies diameter and strides the production of size by 20mm to 63mm, however in order to satisfy the production of undersized tubing, existing mouthful of mould and plug all are the structures of single diameter reduced size; This design is at preparation diameter bigger tubing, and during like the tubing of diameter more than 50mm, briquetting pressure is not enough when causing tube forming easily, and the article construction leakiness can not be through problems such as impact test even tubing withstand voltage properties are low.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of reducing extruder head is provided.Said reducing extruder head can satisfy the preparation of the bigger tubing of diameter, and the physical property of the tubing of preparation gets a promotion.
The above-mentioned purpose of the utility model is achieved through following technical scheme:
A kind of reducing extruder head comprises handpiece body, spreader, mouthful mould and plug, and the material channel that is made up of above-mentioned parts; Said plug is for to be made up of leading portion, stage casing and back segment, is leading portion near a section of handpiece body, is back segment away from a section of handpiece body, is cylindrical, and the diameter of back segment is greater than the diameter of leading portion, and leading portion transits to back segment gradually through the stage casing.
In order to make the consistent wall thickness of tubing, mouthful mould is consistent with the size of the material channel that plug is constituted.
Tubing obtains enough compression ratios at leading portion; Guaranteed and enough briquetting pressures; Make tubing more closely knit, carry out the transition to back segment by leading portion and get in the process, make polymer segment further toward pipe hoop orientation; After cooling, most of physical property of gained tubing (especially withstand voltage properties, impact resistance) is all promoted accordingly like this.
As a kind of preferred version, the diameter of said back segment and leading portion length to diameter ratio are preferably 1.1 ~ 3.
As a kind of more preferably scheme, the diameter of said back segment and leading portion length to diameter ratio more preferably 1.5 ~ 2.5.
The utility model has been done improvement to the mouth mould inside and the plug of conventional extruder head, and the material channel that makes mouthful mould and plug form has the function of reducing, is more suitable for the preparation of the bigger tubing of diameter.The tubing that is come out by back segment because its diameter is bigger, is used with the typing cover and produces large diameter tubing, and its caliber rate of change is less, so the stability of product structure is improved, and yield rate also raises greatly.
As a kind of preferred version, said stage casing and back segment are demountable structure.
Stage casing and back segment are made demountable structure, make the described extruder head of the utility model can produce the less tubing of diameter.When needs prepare the bigger tubing of diameter, connect stage casing and back segment again; Therefore the extruder head of the utility model can be chosen in simply to improve on the existing equipment and get final product, and does not need to design again and brings waste economically.
Compared with prior art, the utlity model has following beneficial effect:
The described reducing extruder head of the utility model; Through reasonable improvement to mouth mould and the plug of conventional extruder head; Be more suitable for producing the bigger tubing of diameter, the stability that it has improved the large scale preparation of pipes has on the one hand improved the withstand voltage properties and the impact resistance of tubing again.
Description of drawings
Fig. 1 is the structural representation of the said reducing extruder head of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further explained, but specific embodiment is not done any qualification to the utility model.
The described reducing extruder head of the utility model is as shown in Figure 1.Comprise handpiece body 1, spreader 2, mouthful mould 3 and plug 4, and the material channel that constitutes by above-mentioned parts; Said plug is for to be made up of leading portion 41, stage casing 42 and back segment 43, is leading portion near a section of handpiece body, is back segment away from a section of handpiece body, is cylindrical, and the diameter of back segment is greater than the diameter of leading portion, and leading portion transits to back segment gradually through the stage casing.
Alternatively, the diameter of said back segment and leading portion length to diameter ratio are 1.1 ~ 3.
Alternatively, said stage casing and back segment are demountable structure.
Tubing obtains enough compression ratios at leading portion; Guaranteed and enough briquetting pressures; Make tubing more closely knit, carry out the transition to back segment by leading portion and get in the process, make polymer segment further toward pipe hoop orientation; After cooling, most of physical property of gained tubing (especially withstand voltage properties, impact resistance) is all promoted accordingly like this.
Claims (4)
1. reducing extruder head comprises handpiece body, spreader, mouthful mould and plug, and the material channel that is made up of above-mentioned parts; It is characterized in that said plug is for to be made up of leading portion, stage casing and back segment, is leading portion near a section of handpiece body, is back segment away from a section of handpiece body, is cylindrical, and the diameter of back segment is greater than the diameter of leading portion, and leading portion transits to back segment gradually through the stage casing.
