Problems solved by technology

In this process, there are the following deficiencies: First, because the upper and lower molds of the mold are generally made of epoxy resin layer, and the steel plate on the back of the mold is welded, after a long period of continuous opening and closing of the upper and lower molds, the epoxy resin layer surface It will often loosen or even fall off with the steel plate, which will affect the production efficiency of the enterprise, and even cause production accidents in serious cases; secondly, in the mold processing process, due to the epoxy resin layer used on the upper and lower surfaces of the mold, it will not last for a long time. During the processing and manufacturing, the horn-shaped protrusions on the profile surface will inevitably wear out, and the material at the tip will be worn off immediatel

Example Embodiment

[0011] A compression mold, the compression mold includes an upper mold 10 and a lower mold 20, the upper and lower molds 10, 20 have the molding surfaces 11, 21 continuously provided with cutting edges 111, 211 matching each other along the product cutting line .

[0012] Further, in order to ensure that the cutting edges 111 and 211 can cut edges smoothly and the cutting edges do not interfere with each other, the clamping distance of the cutting edges 111 and 211 is 10 to 20 threads.

[0013] Since the upper and lower molds 10, 20 are all integrated cast iron structures, when processing the upper and lower molds 10, 20, you can choose to directly make the mold body by casting means, and then process the mold surfaces 11, 21 by CNC machining. The upper and lower dies 10 and 20 can be matched correctly to ensure their accuracy and at the same time solve the problem that the old-fashioned epoxy resin layer profile often looses or even falls off between the reinforced steel plate on ...

Abstract

The invention belongs to the field of automobile interior product machining and manufacturing, in particular to a pressing die. The pressing die comprises an upper die and a lower die, and the profiles of the upper die and the lower die are provided with continuous and mutually matched cutting edges along the cutting lines of the product. When the pressing die is used, because the pressing and the edge cutting of the product are completed once, later machining is avoided and machining procedures are reduced, the production efficiency of the enterprise is increased. Meanwhile, because the continuous cutting edges directly cut off excessive materials while pressing and molding the product, the side lines of the molded product are trim and beautiful, the product does not require polishing procedure after edge cutting, and a threat to the health of workers and the pollution to the environment due to fiber dust produced by polishing are also avoided.

Description

technical field [0001] The invention belongs to the field of processing and manufacturing of automobile interior decoration products, and in particular relates to a pressing die. Background technique [0002] In the field of processing and manufacturing of automotive interior products, hemp fiberboard is widely used due to its advantages of uniform material, small vertical and horizontal strength difference, and not easy to crack. The molding surface of the existing molds for forming hemp fiber boards is generally an epoxy resin layer, and a circle of continuous angular protrusions are arranged on the molding surface of the upper mold or the lower mold along the contour line of the processed product, and the corresponding other The profile is smooth, and the back of the profile is welded and reinforced with steel plates. During production and processing, first put the hemp fiberboard into the heating room to heat. After the PP component in the hemp fiberboard is heated and ...
