Abstract
The utility model relates to a combination die for producing a plastic pipe with color threads, which consists of a die 1, a die 2 and a core die, wherein the position on the die 1 close to an outlet is provided with a feed inlet; the position on the die 2 close to an outlet is provided with a groove; one or more color thread holes are uniformly distributed on the groove; in the combining process, the die 2 is sleeved in the die 1 and the groove of the die 2 is communicated with the feed inlet of the die 1; and the core die is sleeved in the die 2 and a gap serving as the feed inlet is reserved between the core die and the die 2. The combination die can effectively solve the processing difficulties of the double-color co-extrusion die, can avoid waste of the dies and also guarantees sufficient bonding of the color threads and the pipe body to make the product have good appearance quality.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of assembling die that is used to make band colo(u)r streak plastic pipe.
Background technology
Many plastic pipes must have colo(u)r streak because of its purposes decision, and for example the remaining needle sleeve pipe needs to inlay four or many X-ray development colo(u)r streaks on body.Can produce the plastic pipe of many colors with several different methods, wherein adopting coextrusion processes is the most simple and easy to do a kind of method.During coextrusion, when particularly precision is extruded,, guarantee the quality of tubing,, need in extrusion molding, promptly on body, inlay colo(u)r streak as requirements such as surface brightness, intensity, hardness, thermoforming and colorings in order to give full play to the inherent feature of material.A mouthful mould all is designed to single integral body in the tradition co-extruding mould, be on same axis machining screw and superfine colo(u)r streak hole, extremely require to differ totally different, axiality requires high again, its difficulty is well imagined.Also because the single global design of tradition mouthful mould makes it can only be used for supporting with it head and core, if through after the using and polishing repeatedly, endoporus can become greatly, and the product of producing does not just reach requirement, and even can not use, and needs manufacturing again.Will cause waste of material like this.
Summary of the invention
Main purpose of the present utility model is to provide a kind of can satisfy band colo(u)r streak plastic pipe production demand, is convenient to the assembling die of processing, being convenient to change again.
For achieving the above object, assembling die of the present utility model is made up of three parts: mouthful mould one, mouthful mould two, core.Mouth mould one nearly export department bit strip has a charging aperture; Mouthful mould two has a circle groove near exits, has one or be uniform-distribution with a plurality of colo(u)r streaks hole on the groove.During combination, a mouthful mould two is enclosed within mouthful mould one, and its groove is communicated with the charging aperture of mouthful mould one; Core is enclosed within mouthful mould two, and leaves the gap as charging aperture between itself and mouthful mould two.
The utility model is opened sizing section place at the mouth mould with co-extrusion inlet and colo(u)r streak hole, make two kinds of materials along oneself flow passage independently, converge common extrusion neck ring mold in access hole mould exit, the colo(u)r streak melt is compound with superfine width and thickness as thin as a wafer and plastic raw materials melt, and be extruded together outside the mould, again through calibration sleeve and water tank cooling forming.The utility model designs sizing section longly slightly simultaneously, increase the distance after collaborating, except that enough big adhesion pressure is provided for two kinds of materials, also increased the resistance that plastic melt flows in the gap, thereby increased fusant density greatly, make the product plasticizing evenly, packing is higher, residual rotation behind the further elimination process screen and the internal stress that causes through the spreader pillar, improve the service life of product, also guaranteed the fully bonding of colo(u)r streak and body, made product have the good surface appearance quality.
According to above technical scheme, the utlity model has following advantage:
1. need only difference machining screw and colo(u)r streak hole on mouth mould one and mouthful mould two when making, can carry out simultaneously at different lathes fully, both satisfied designing requirement, improved efficient again.
2. when needing to change because of wearing and tearing, only need counterpart mould two to change, the entire die of need not reforming has been avoided waste of material.
3, lengthening calibration sleeve, increase the distance after collaborating, except that enough big adhesion pressure is provided for two kinds of materials, has also increased the resistance that plastic melt flows in the gap, thereby increased fusant density greatly, make the product plasticizing evenly, packing is higher, residual rotation behind the further elimination process screen and the internal stress that causes through the spreader pillar, the service life of improving product, also guaranteed the fully bonding of colo(u)r streak and body, made product have the good surface appearance quality.
Description of drawings
Fig. 1 is each block diagram of the utility model, and wherein label 1 is a mouthful mould one, and label 2 is a mouthful mould two, and label 3 is a core.
Fig. 2 is the schematic diagram after the utility model combination, and wherein label 1 is a mouthful mould one, and label 2 is a mouthful mould two, and label 3 is a core, and label 4 is the co-extrusion track, and label 5 is a charging aperture one, and label 6 is a groove, and label 7 is the colo(u)r streak hole, and label 8 is a charging aperture two.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
A kind of assembling die that is used to make band colo(u)r streak plastic pipe comprises mouthful mould 1, mouthful mould 22, and core 3 is assembling successively from outside to inside.During co-extrusion manufacturing band colo(u)r streak plastic pipe, plastic matrix is added from charging aperture 28, color masterbatch adds from charging aperture 1, and color masterbatch is full of groove 6 and enters co-extrusion track 4 by colo(u)r streak hole 7, with the plastic matrix co-extrusion, finally makes the plastic pipe of band colo(u)r streak.
It below only is concrete preparation example of the present utility model; protection domain of the present utility model is not constituted any limitation. in addition to the implementation; the utility model can also have other embodiments. and all employings are equal to the product of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
Claims (3)
1. an assembling die that is used to make band colo(u)r streak plastic pipe is made up of mouth mould and core, it is characterized in that: independently parts---form, and mouth mould two is enclosed within mouthful mould one during use by mouthful mould one, a mouthful mould two by two for mouthful mould.
