Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses inflation film manufacturing machine mould. Referring to fig. 1 and 2, a inflation film manufacturing machine mould, including being cylindric mould body 1 and being circular shape fixed disk 2, be provided with on mould and the fixed disk 2 and be circular shape fixing hole 5, and be provided with the mounting 6 of fixed mould body 1 and fixed disk 2 in the fixing hole 5, and then make mould body 1 can dismantle the setting on fixed disk 2, and mounting 6 can be the bolt in this embodiment. The mold body 1 comprises a cylindrical inner mold 101, a cylindrical middle mold 102 and a cylindrical outer mold 103, wherein the inner mold 101 is sleeved in the middle mold 102, the middle mold 102 is sleeved in the outer mold 103, and a spiral guide groove 3 which is spirally raised is arranged on the peripheral wall of the mold body 1 far away from the fixed disk 2. The fixing piece 6 is inserted into the fixing through hole 5, so that the die body 1 is sequentially fixed on the fixing disc 2, when materials are guided into the die body 1, the materials uniformly flow to the die head from the spiral guide groove 3, and then the extruded materials are more uniform, and a heavy film with uniform thickness is formed; when needs wash the mould, the accessible is dismantled mounting 6 and is dismantled mould body 1 from fixed disk 2 and get off, and then washs mould body 1, makes the washing to mould body 1 more convenient.

A material guide groove 4 is arranged on the peripheral wall of the die body 1 close to the fixed disc 2, and one end of the material guide groove 4 far away from the fixed disc 2 is communicated with the spiral guide groove 3. When the material is guided into the die body 1, the material flows into the spiral guide groove 3 from the guide groove 4, so that the contact area between the material and the die body 1 is reduced, the falling speed of the temperature of the material is reduced, and the material is uniformly extruded from the die head.

The guide cross section of the spiral guide groove 3 along the guide direction is gradually reduced. The material flows to die head department from spiral guide slot 3, in order to make the more even extrusion from the die head of material, reduces spiral guide slot 3's cross-section gradually, and the screw speed when can making the material extrude is faster, and the ejection of compact is more even, forms the even heavy membrane of thickness.

The fixed disc 2 comprises a circular inner ring 201, a middle ring 202 and an outer ring 203, the inner ring 201 is clamped with the inner side wall of the inner die 101, the middle ring 202 is clamped with the inner side wall of the middle die 102, and the outer ring 203 is clamped with the inner side wall of the outer die 103. The inner ring 201, the middle ring 202 and the outer ring 203 on the fixed disc 2 are sequentially clamped with the die body 1, so that the materials among the inner ring 201, the middle ring 202 and the outer ring 203 are prevented from being mixed, and the film blowing quality is ensured.

The peripheral wall of the outer mold 103 away from the inner mold 101 is provided with an insulating layer 7. The insulating layer 7 in this embodiment may be a foam layer. Through setting up heat preservation 7, can keep warm to the material in the mould body 1, be favorable to making the material keep the molten state, and then even extrude from the die head.

One end of the die body 1 far away from the fixed disc 2 is provided with a conical inclined surface 8. When the material is extruded from the die head, the material can be uniformly converged on the conical inclined surface 8 by utilizing the rotating direction of the conical inclined surface 8, and a heavy film with uniform thickness is formed.

The implementation principle of the film blowing machine mould in the embodiment of the application is as follows: the die body 1 is inserted into the fixing through hole 5 through the fixing piece 6 in sequence and fixed on the fixing disc 2, materials are guided into the guide chute 4, the materials flow into the spiral guide groove 3 from the guide chute 4, the cross section of the spiral guide groove 3 is gradually reduced, the materials are uniformly extruded from the die head, the materials are uniformly converged on the conical inclined surface 8, and finally a heavy film with uniform thickness is formed. The inner ring 201, the middle ring 202 and the outer ring 203 on the fixed disc 2 are clamped with the die body 1, so that a closed space is formed between the die bodies 1, the contact between materials and the outside is avoided, the temperature is reduced, and the heat preservation layer 7 on the outer die 103 also avoids the phenomenon that the temperature of the materials is reduced too fast to cause uneven thickness of an extruded heavy film.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
