Abstract
The utility model discloses a die with non-uniform die mouth gap for producing thin-wall maze-type drip tapes. The die comprises an outer die, a die core arranged in the outer die, a die mouth gap formed between the die core and the outer die, and a groove formed on the outer wall of the outer die or on the outer wall of the die core. By adopting the groove, the die can reduce the wall thickness and lower the cost of the maze-type drip tape without changing the thickness of the maze wings of the maze-type drip tape. The die has the advantages of reduced production cost, improved product quality, etc.
Description
Technical field
The utility model relates to the drip irrigation zone production field, specifically is a kind of non-equal formula die gap mould that thin wall labyrinth formula drip irrigation zone produces that is used for.
Background technology
Labyrinth type drip irrigation tape is kind of a very effective water-saving irrigation product.But in labyrinth type drip irrigation tape used, the drip irrigation zone was very easy to from " labyrinth " quick-fried band take place.Therefore, in the growth course of labyrinth type drip irrigation tape, has enough intensity in order to ensure manufactured goods, can only adopt the method that keeps certain manufactured goods wall thickness, this causes the production cost of labyrinth type drip irrigation tape to increase, and is promoting the use of of labyrinth type drip irrigation tape on a large scale, brings very big difficulty.
Summary of the invention
The purpose of this utility model provides a kind of non-equal formula die gap mould that thin wall labyrinth formula drip irrigation zone produces that is used for, it can be located under the constant situation of thickness in " labyrinth " that keep labyrinth type drip irrigation tape, reduce the pipe thickness of labyrinth type drip irrigation tape, thereby reduce materials, reduce cost.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of non-equal formula die gap mould that is used for the production of thin wall labyrinth formula drip irrigation zone, comprise adventitia, core rod is set in the adventitia, core rod and the outer intermembranous die gap that is provided with are offered groove on the adventitia inwall or on the core rod outer wall.Evenly offer first groove and second groove on the adventitia inwall.Evenly offer the 3rd groove and the 4th groove on the core rod outer wall.The groove inner surface is a curved surface.Pore is offered at the core rod middle part.The adventitia cross section is an annular.
Advantage of the present utility model is: by groove is set, can reduce the labyrinth type drip irrigation tape wall thickness under the situation that the labyrinth wing thickness that keeps labyrinth type drip irrigation tape remains unchanged, reduce cost.The utlity model has and to reduce production costs; Advantage such as improve the quality of products.
Description of drawings
The specific embodiment
Agent structure of the present utility model is: a kind of non-equal formula die gap mould that is used for the production of thin wall labyrinth formula drip irrigation zone, comprise adventitia 2, core rod 5 is set in the adventitia 2, and 2 of core rod 5 and adventitias are provided with die gap 3, are offering groove on adventitia 2 inwalls or on core rod 5 outer walls.So in use, material is extruded from die gap 3, form the tubular material base, the tubular material base removes each point consistency of thickness on the groove excircle, the material base of groove of flowing through is thicker, press through vacuum forming device absorption is sticking then, it is thicker to produce the part, the drip irrigation zone goods that other position thickness is evenly thin.Like this, the position that material base is thicker can be used to process " labyrinth " position on the drip irrigation zone, can guarantee that " labyrinth " locate requirement of strength, prevent the drip irrigation zone use in from " labyrinth " explosion.
The structure of one of the utility model embodiment is: stressedly evenly be beneficial to bondingly in order to guarantee that the tubular material base is whole, offer 180 ° at interval of first groove 1 and second groove, 7, the first grooves 1 and second grooves 7 on adventitia 2 inwalls.
Two the structure of the utility model embodiment is: stressedly evenly be beneficial to bondingly in order to guarantee that the tubular material base is whole, offer 180 ° at interval of the 3rd groove 8 and the 4th groove 6, the three grooves 8 and the 4th grooves 6 on core rod 5 outer walls.
Certainly, can offer a groove on adventitia 2 inwalls or on core rod 5 inwalls, but the final molding effect is not so good as above-mentioned two embodiment like this; Also can offer 3,4 or a plurality of groove on adventitia 2 inwalls or on core rod 5 inwalls, but increase cost.
The groove inner surface can be made curved surface, and the thicker material base part-structure of Xing Chenging is fastening like this, reduces stress and concentrates, and is beneficial to moulding.Offer pore 4 at core rod 5 middle parts, can in the tubular material base, dry by pore 4 and adjust tubular material base size.Adventitia 2 has multiple shape, and in order to reduce the cost of mould, adventitia 2 cross sections are done and circularized.Mould in the utility model can be used to produce individual layer thin wall labyrinth formula drip irrigation zone, also can be used for production multilayer thin-walled labyrinth type drip irrigation tape.
