Abstract
The invention relates to an extrusion die head. The extrusion die head comprises an upper die head and a lower die head, wherein the upper die head is connected with the lower die head by a side baffle; the lower die head is internally provided with two movable die openings which are arranged in parallel; the outer side of each movable die opening is connected with a guiding block; each guiding block is arranged on the inner side of the side baffle; and the lower die head is internally provided with a runner. The extrusion die head has the advantages that the difficulties caused by repairing and maintenance are lowered, and meanwhile, the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of extrusion molding mould.
Background technology
The function of extrusion dies makes the plastic melt from extruder barrel, well distributed in die head runner, to extrude and shaping from die orifice under uniform speed.Extrusion dies shaping acts in whole extrusion process most important.
The product of production is in the past single, so old-fashioned die head is all designed to fixed dimension, so just cause the unicity of production kind, just in case when encountering the product needing to produce different size specification, just need the die head of the whole series to disassemble from equipment, change a whole set of die head of new size, so not only waste time and energy, increase the labour intensity of on-site maintenance workman, increase maintenance cost, have impact on again the production and processing cycle simultaneously, reduce production efficiency.And because old-fashioned die head is that size is fixed, so require to make corresponding die head one by one according to different product sizes, the cost of the equipment so not only increased, what turn increase equipment administers and maintains cost.
As shown in Figure 1, old-fashioned extrusion dies is divided into upper die head, lower die head, die orifice three part, and installing combines just becomes a set of extrusion dies.
Upper die head and equipment head are connected and fixed, and are imported in extrusion dies by the fluid of head.
Lower die orifice belongs to the interim orbit of upper die head and die orifice, the fluid of importing is carried out in the inner flow passage designed reasonable shunting at the uniform velocity, ensures that the pressure that fluid is gone out from die orifice is consistent.
Die orifice and upper and lower die head are connected and fixed, and for the fluid shunted being fixed the shape of outflow, ensure that fluid flows out under rational speed, pressure, shape in extrusion dies.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of demand regulating die orifice size to produce to meet different product is provided, same extrusion dies can be produced through trickle adjustment the product of different size specification, and do not need a whole set of extrusion dies to pull down from equipment to change brand-new extrusion dies, avoid installing/dismounting work repeatedly, and through reasonably design, the maintenance of extrusion dies is more reasonably simple, not only reduce numerous and diverse difficulty of maintaining and bringing, turn improve the extrusion dies of the efficiency of production simultaneously.
Object of the present invention is achieved through the following technical solutions: a kind of extrusion dies, comprise upper die head and lower die head, be connected by side shield between upper die head and lower die head, two movable die orifices placed side by side are provided with in lower die head, the outside of each movable die orifice is all connected with guide pad, guide pad is placed in the inner side of side shield, is provided with runner in lower die head.
Further improvement of the present invention is: described upper die head and equipment head are fixed, for being imported in extrusion dies by the fluid in head.
Further improvement of the present invention is: described guide pad is fixed by set bolt.
The present invention compared with prior art has the following advantages: by the demand regulating die orifice size to produce to meet different product, same extrusion dies can be produced through trickle adjustment the product of different size specification, and do not need a whole set of extrusion dies to pull down from equipment to change brand-new extrusion dies, avoid installing/dismounting work repeatedly, and through reasonably design, the maintenance of extrusion dies is more reasonably simple, not only reduce numerous and diverse difficulty of maintaining and bringing, turn improve the efficiency of production simultaneously.
accompanying drawing illustrates:
Fig. 1 is the structural representation of existing extrusion dies;
Fig. 2 is structural representation of the present invention;
Number in the figure: 1-upper die head, 2-lower die head, 3-side shield, 4-movable die orifice, 5-guide pad, 6-die orifice.
detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
The embodiment of a kind of extrusion dies of the present invention as shown in Figure 2, comprise upper die head 1 and lower die head 2, be connected by side shield 3 between upper die head 1 and lower die head 2, two movable die orifices 4 placed side by side are provided with in lower die head 2, the outside of each movable die orifice 4 is all connected with guide pad 5, guide pad 5 is placed in the inner side of side shield 3, is provided with runner in lower die head 2.Upper die head 1 of the present invention is fixed with equipment head, and for being imported in extrusion dies by the fluid in head, guide pad 5 is fixed by set bolt.
Extrusion dies of the present invention is to solve the deficiencies in the prior art, devise new-type extrusion dies, the demand that new-type extrusion dies is produced by regulating die orifice size to meet different product, same extrusion dies can be produced through trickle adjustment the product of different size specification, and do not need a whole set of extrusion dies to pull down from equipment to change brand-new extrusion dies, avoid installing/dismounting work repeatedly, and through reasonably design, the maintenance of extrusion dies is more reasonably simple, not only reduce numerous and diverse difficulty of maintaining and bringing, turn improve the efficiency of production simultaneously.
New-type extrusion dies is divided into upper die head 1, lower die head 2, movable die orifice 4, guide pad 5, and part such as side shield 3 grade forms.
Upper die head 1 and equipment head are connected and fixed, and are imported in extrusion dies by the fluid of head.
Movable die orifice 4 belongs to the interim orbit of upper die head 1 and lower die head 2, the fluid of importing is carried out in the inner flow passage designed reasonable shunting at the uniform velocity, ensures that the pressure that fluid is gone out from die orifice is consistent.
Movable die orifice 4 is connected and fixed with upper and lower die head, for the fluid shunted being fixed the shape of outflow, ensures that fluid flows out under rational speed, pressure, shape in extrusion dies.Movable die orifice 4 is designed to adjustable, does up-down adjustment then fixed by set bolt by guide pad 5 guiding.
