Abstract
The utility model discloses a mold for plastic pipes. The mold comprises a mold body, a flow distributing bracket, a flow distributing cone, a mouth mold, a mandrel, an adjusting bolt and a centering sleeve, wherein the centering sleeve is designed into a corresponding annular structure according to the size and wall thickness of the pipes; and during mold combination, the centering sleeve is sleeved on the mandrel, and the annular wall of the centering sleeve is snapped between the mandrel and the mouth mold. The mold has the beneficial effects that during mold replacement, the centering sleeve of a corresponding size is inserted between the mouth mold and the mandrel so as to play a role in concentric locating, then, the bolt of the mouth mold is locked, and the centering sleeve is extruded out by using material flow when the temperature reaches the requirements of startup discharging; and the problems of empirically manual mounting and repeated measurement and adjustment during mounting are solved, the locating is completed by only inserting the centering sleeve between the mouth mold and the mandrel during mold assembly and is quick, simple and convenient, the technical requirements for mold assembly are lowered greatly, and the time for mold assembly is shortened greatly.
Description
Technical field
The utility model relates to the pipe mold field, relates in particular to a kind of plastic pipe die of centering function, is applied to the adjustment of plastic pipe die wall thickness.
Background technology
Common plastic pipe die structure is as schemed: die body, shunting support, spreader, mouthful mould, plug, adjustment bolt, consist of; every mold all can design tubing such as the Ф 50-75 mould of producing several close specification external diameters; can produce Ф 50,63,75 3 kind of tubing; every kind of tubing has again the product of several different wall; by changing corresponding mouth mould, plug, can produce the pipe material product of various outer diameter and wall thickness, so can there be the situation of frequent die change.
The problem of centering in the time of will existing mouthful mould and plug to install when die change, once the tube wall thickness that the installation decentraction is produced accordingly also can be eccentric, cause the non-compliant products such as the partially thin or bending pipes of tube wall thickness, by the tubing to producing, measure and adjust again wall thickness, but this moment, product was produced tens of rice, present installation process is all generally to be undertaken by operator's experience and range estimation, though the large available slide calliper rule of product of wall thickness or clearance gauge are measured all the time, also can have deviation.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, mouthful mould and the plug plastic pipe die of centering fast is provided.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of plastic pipe die, comprise die body, shunting support, spreader, mouthful mould, plug and adjustment bolt, also comprise centring sleeve, described centring sleeve is according to size and the corresponding circulus of wall thickness design of tubing, during die assembly, described centring sleeve is socketed on plug, and the ring wall of centring sleeve is connected between plug and mouthful mould.
For service life of extending centring sleeve and can not scratch mould, the utility model is further optimized, and the material of described centring sleeve is polytetrafluoroethylene (PTFE).
More convenient for centring sleeve is pegged graft, the utility model is further optimized, and the excessive angle of ring-type one side of described centring sleeve is chamfering structure.
More convenient for centring sleeve is pegged graft, the utility model is to the another kind of optimal way of centring sleeve, and ring-type one side of described centring sleeve is designed to pyramidal structure.
More convenient for centring sleeve is pegged graft, the utility model is to the another kind of optimal way of centring sleeve, and described centring sleeve integral body is the tapered annular structure.
The beneficial effects of the utility model, do use by between the centring sleeve insert port mould of corresponding size, plug, playing concentric locating when die change, again by mouth mould bolt-locking, utilize material stream that centring sleeve is extruded this moment when temperature arrives the start discharge.Solve artificial problem of installing by rule of thumb, and installation process measurement adjustment repeatedly, only need be when the dress mould have completed location between by centring sleeve insert port mould, plug, fast and convenient and greatly reduce the specification requirement of dress mould and the time of dress mould.Use centring sleeve to guarantee the definitely concentric of mouthful mould and plug, the product produced of starting shooting, without carrying out the wall thickness adjustment, has reduced the quantity of defective work again, has greatly saved the start cost.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model plastic pipe die.
Wherein:
1: die body; 2: the shunting support; 3: spreader; 4: mouthful mould; 5: plug; 6: adjust bolt; 7: centring sleeve.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
See also Fig. 1, as shown in the figure, the utility model plastic pipe die, comprise die body 1, shunting support 2, spreader 3, mouthful mould 4, plug 5 and adjust bolt 6, also comprising centring sleeve 7, described centring sleeve 7 is according to size and the corresponding circulus of wall thickness design of tubing, be that the shape of centring sleeve 7 is just as one section plastic tube, during die assembly, described centring sleeve 7 is socketed on plug 5, and the ring wall of centring sleeve 7 is connected between plug 5 and mouthful mould 4.By said structure, when die change, by between the centring sleeve of corresponding size 7 insert port moulds 4, plug 5, playing concentric locating, do use, will adjust again bolt 6 lockings this moment, when arriving the start discharge, temperature utilize material stream that centring sleeve 7 is extruded.Solve artificial problem of installing by rule of thumb, and installation process measurement adjustment repeatedly, only need be when the dress mould have completed location between by centring sleeve insert port mould, plug, fast and convenient and greatly reduce the specification requirement of dress mould and the time of dress mould.Use centring sleeve to guarantee the definitely concentric of mouthful mould and plug, the product produced of starting shooting, without carrying out the wall thickness adjustment, has reduced the quantity of defective work again, has greatly saved the start cost.
In the present embodiment, the material of described centring sleeve is polytetrafluoroethylene (PTFE), and polytetrafluoroethylene belongs to the heat-resistant, wear-resistant material, long service life and can not scratch mould, and the easy making process cost is low.
More convenient for centring sleeve is pegged graft, in the present embodiment, centring sleeve can have several improvement, and the excessive angle of ring-type one side of the described centring sleeve of one is chamfering structure; Ring-type one side of its two described centring sleeve is designed to pyramidal structure, and namely centring sleeve one side can be fined away a little; Its three described centring sleeve integral body is the tapered annular structure, namely from an end, looks over, and the ring wall of centring sleeve is taper.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims 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 scope of patent protection of the present utility model.
