Description

technical field [0001] The invention relates to a foam molding machine, in particular to a CNC four-axis automatic mold-free molding machine. CNC is computer numerical control, and CNC molding machine is computer numerical control molding machine. CNC molding machine realizes multi-axis linkage processing through program control, so that the tool can automatically shape the workpiece according to the set shape. It is mainly suitable for the processing of rectangular, circular, triangular and other single or comprehensive geometric shapes of through holes or blind holes in foam materials in the packaging industry, and belongs to the technical field of foam processing equipment and equipment. Background technique [0002] Because the foam material has the advantages of lightness and good compression resistance, it can effectively prevent product damage and bumps during transportation and handling, and it can fix and protect the packaged products, and the cost is low. Therefore...

Problems solved by technology

At present, there are several forms of foam molding: one is foam molding through a special mold, but the problem with this foam molding is that it is suitable for mass production, and the packaged products are in the stage of development and trial production or small batch production, or It is a customized product and the production quantity is not very large. If the foam packaging material is made by a special mold, a relatively high packaging cost will be incurred, and once the packaged product is terminated or the production variety is changed or the product is updated Finally, it will cause great waste and cost increase due to the inability to use the special mold. Therefore, this special mold molding has been gradually replaced by the second type of molding machine, that is, the mold-free molding machine; the second type is currently commonly used The two mold-free molding machines do not require special molds, and the foam is processed and formed by heating the heating wire connected to the heating wire transformer. One of the foam-free molding machines is a simple manual foam-free molding machine. This kind of manual foam-free molding machine can only realize the Z-up and down movement of the processing head equipped with the heating wire, and it needs manual operation to make the processed foam move on the workbench. This kind of manual foam-free molding machine can only process relatively simple The rectangular shape or straight line cutting, and the manual operation molding accuracy is relatively low, the quality of the processed packaging foam is relatively poor, the labor efficiency is low, and the labor intensity of the workers is high. Adapt to the requirements of modernization and scale; another type of foam free molding machine is a two-dimensional CNC free molding machine, that is, a two-dimensional computer numerical control free molding machine, including a numerical control computer, a heating wire transformer and a heating wire, and a It includes a bed, a workbench, a column and a beam, and also includes a Z-direction sliding device. The Z-direction sliding device of the computer numerical control mold-free forming machine is set on the column, and the workbench is fixed. Two-dimensional molding is realized through computer program control. There are only two axial linear movements in the X and Z directions. Therefore, the defect of this CNC mold-free forming machine is that its heating wire must pass through the foam material, and it can only process through-holes with geometric dimensions, which cannot meet the processing of complex geometric shapes in the packaging industry.
