Abstract
The utility model discloses a pipe extrusion die which comprises an internal die and an external die, wherein a plurality of groups of heating parts which are not overlapped with one another are wound on the outer wall of the external die; each heating part comprises two electrical heating pieces which are symmetrical about the central axis of the external die; the electrical heating pieces are respectively connected with a temperature sensor and a temperature control module which are connected with a control system. The outer wall of the external die is provided with the plurality of electrical heating pieces, so that the thickness of the wall of the extruded pipe can be indirectly adjusted by collecting and adjusting the heating temperature of the electrical heating pieces, and the pipe is even in wall thickness and better in quality.
Description
Technical field
The utility model relates to tubing manufacturing technology field, particularly a kind of tubing extrusion die.
Background technology
Tubing is made in the forming process, and the plastic raw materials after often using extruder with heating and melting is extruded, and cooling and shaping.The tubing extrusion die is arranged on the extruder end, comprise that the cross section is internal mold, the external mold of annular and a heating plate that arranges around the external mold outer wall, leave the passage of extruding that the cross section is similarly annular between internal mold and the external mold, under the perfect condition, internal mold and external mold are coaxial settings, the cross section of extruding passage is a standard annular, also is a standard annular by the tubing cross section of extruding the passage extrusion molding, i.e. tubing pipe thickness uniformity everywhere.
But, the relative position of internal mold and external mold more or less has deviation in the actual installation process of tubing extrusion die, and this moment, the channel cross-section of extruding of the two was not a standard annular, by extruding the tubing of passage extrusion molding, the pipe thickness thickness differs, and has reduced the quality of product.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of tubing extrusion die, to reach the pipe thickness of timely adjustment tubing, makes its pipe thickness even, the purpose that quality is better.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of tubing extrusion die, comprise internal mold and external mold, on the outer wall of described external mold around the heater block that is provided with the array non-overlapping copies, described heater block comprises two about the symmetrically arranged electric heating sheets in described external mold axis, described electric heating sheets all is connected with temperature sensor and temperature control module, and described temperature sensor and described temperature control module are connected with control system.
Preferably, described control system is the PLC control system.
Preferably, described temperature sensor is contact type temperature sensor.
Pass through technique scheme, a kind of tubing extrusion die that the utility model provides is provided with the several piece electric heating sheets at the external mold outer wall, when the tube material and tube wall variable thickness of extruder for shaping causes, by gathering and adjust the heating-up temperature of electric heating sheets, adjust the pipe thickness of extruding pipe material indirectly, thereby offset internal mold and external mold relative position deviation to the influence of pipe thickness, can make tube material and tube wall thickness even, quality is better.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the disclosed a kind of tubing extrusion die structural representation of the utility model embodiment.
The represented corresponding component title of numeral among the figure:
1, internal mold 2, external mold 3, electric heating sheets 4, temperature sensor 5, temperature control module
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
According to Fig. 1, the utility model provides a kind of tubing extrusion die, comprise internal mold 1 and external mold 2, on the outer wall of external mold 2 around the heater block that is provided with two groups of non-overlapping copies, heater block comprises two, and electric heating sheets 3 all is connected with temperature sensor 4 and temperature control module 5 about the symmetrically arranged electric heating sheets 3 in external mold 2 axis, and temperature sensor 4 and temperature control module 5 are connected with the PLC control system, wherein, temperature sensor 4 is contact type temperature sensor.
When the tube material and tube wall variable thickness of extruder for shaping causes, PLC control system control temperature control module 5 is turned down electric heating sheets 3 temperature of the thick partially side of pipe thickness, and with the thin partially side of pipe thickness (with the thick partially side of pipe thickness about external mold 2 axis symmetries) electric heating sheets 3 temperature heighten; Known, the cohesive force of the more high plastics of temperature is more low, and flowability is more strong, and after electric heating sheets 3 temperature of the thin partially side of pipe thickness were heightened, the temperature of its homonymy plastic raw materials also increased, and the corresponding lifting of rate of extrusion makes the pipe thickness thickening; Otherwise, after electric heating sheets 3 temperature of the thick partially side of pipe thickness are turned down, its homonymy pipe thickness attenuation.
A kind of tubing extrusion die that the utility model provides is provided with four electric heating sheets 3 at external mold 2 outer walls, by gathering and adjust the heating-up temperature of electric heating sheets 3, adjust the pipe thickness of extruding pipe material indirectly, thereby offset internal mold 1 and external mold 2 relative position deviations to the influence of pipe thickness, can make tube material and tube wall thickness even, quality is better.
To the above-mentioned explanation of disclosed a kind of tubing extrusion die embodiment, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
1. tubing extrusion die, comprise internal mold and external mold, it is characterized in that, on the outer wall of described external mold around the heater block that is provided with the array non-overlapping copies, described heater block comprises two about the symmetrically arranged electric heating sheets in described external mold axis, described electric heating sheets all is connected with temperature sensor and temperature control module, and described temperature sensor and described temperature control module are connected with control system.
2. a kind of tubing extrusion die according to claim 1 is characterized in that, described control system is the PLC control system.
