Compare with the integral type core of roll of shaping among the prior art of figure 3, under the condition of using 2 materials of mould to make metal mold 2 with the volume, only can prepare a core of rolling up among the prior art, and mould 2 in this embodiment can prepare 9 sections assembly strips simultaneously, and the core of rolling up in this embodiment adopts 1 assemblies of three-section assembly strip to form, consequently, adopts 2 cores of mould in this embodiment can prepare 3 cores simultaneously, the production efficiency of the core of rolling up that improves greatly.

The following is further explained with reference to an example of the present invention:

the required dimension specification of this assembled book core is:

the inside diameter is 200mm, the wall thickness is 4.2mm, and the height is 18 mm. The assembled winding core is adopted to replace a paper winding core (the inner diameter is phi 200mm, the wall thickness is 7mm, and the height is 18mm), so that the mechanical tension of the tensioning head of the winding machine is met, no fracture exists, and the winding effect is consistent. The later application effects such as supporting force, roundness maintenance and the like are obviously superior to those of the paper winding core; the performance of the core is basically consistent with that of an integral injection molding core with the same size.

This assembled rolls up 2 technical specification of core injection mold:

the specification of the injection mold 2 was set to 260mm × 260 mm. Compare with the core of same size integral type injection moulding, under same 2 basic dimensions of mould, can overall arrangement 9 sections assembly strip 1, can assemble 3 finished product ring form cores of rolling up. The injection molding production efficiency is substantially improved to the original 300 percent. Assuming that the mold 2 has the same output, the injection mold 2 is miniaturized, and the injection molding machine can be a small and light machine, so that the energy is saved and the consumption is reduced.

The comparison of integrated into one piece's core and assembled core in this example at the space utilization of effective packing, transportation, storage is shown in the following table:

as can be clearly seen from the above table, the effective packaging utilization rate of the assembled winding core is improved by 8-9 times under the same packaging volume and specification; the packing quantity and the storage capacity of the products can be greatly improved, and the packing cost and the storage operation cost can be effectively improved. The logistics transportation space and the cost can be correspondingly reduced.

The material of the mounting strip 1 in this embodiment is an injection molding material known to those skilled in the art, such as plastic or plastic.

Finally, it is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications are to be considered as the protection scope of the invention.
