Embodiment 1

[0030] according to figure 1 The surface concave-convex process of a three-dimensional pulp molded product is shown, and the specific process steps are as follows:

[0031] Step 1: Design the pulp mold. The mold body 1 includes the upper mold 2 for the convex and the lower mold 3 for the concave. The upper mold 2 for the convex and the lower mold 3 for the concave. The upper mold 2 is provided with a concave-convex upper mold 8 in the processing graphic part, and the concave-convex shape of the processed graphic part is opposite to the direction of the processed product graphics. The concave lower mold 3 is provided with a concave lower mold 14 in the processed graphic part, and the processing The concave-convex shape of the post-graphic part is the same as the direction of the processed product graphic;

[0032] Step 2: Pulp mold processing, (1) select the material used for the upper mold 2 and the lower mold 3 to be copper or stainless steel; (2) according to the pulp mold ...

Embodiment 2

[0037] according to Figure 2-3 The three-dimensional pulp mold shown includes a mold body 1, and the mold body 1 includes a convex upper mold 2 and a concave lower mold 3, and the convex upper mold 2 includes a guide post upper plate 4, and the guide post The bottom of the upper plate 4 is fixed with an upper fixed splint 5, the bottom of the upper fixed splint 5 is fixed with an upper template 6, the bottom of the upper template 6 is fixed with an upper module 7, and the bottom of the upper module 7 is fixed with a Hitting the convex upper mold 8, the concave lower mold 3 includes a guide post lower plate 9, the top of the guide post lower plate 9 is fixed with a lower fixed splint 10, and the top of the lower fixed splint 10 is fixed with a backing plate 11. The top of the backing plate 11 is fixed with a lower template 12, the top of the lower template 12 is provided with a mold cavity 13, and the bottom of the inner cavity of the mold cavity 13 is fixed with a concave low...

Embodiment 3

[0040] according to Figure 2-3 Shown is a mold for the concave-convex process on the surface of three-dimensional pulp molding products. The concave-convex lower mold 3 is set on the bottom of the convex upper mold 2, and the guide post upper plate 4 is provided with mounting holes, which is convenient for placing the concave-convex mold. The convex upper mold 2 is installed at the bottom of the mold clamping lift rod on the injection molding machine, the four corners of the bottom of the guide post upper plate 4 are provided with guide posts 15, the top four corners of the guide post lower plate 9 are provided with positioning holes 16, and the guide posts 15 and the positioning hole 16 are movable and clamped, which is convenient for guiding and positioning the upper mold 2 for hitting the convex, so that it can be accurately positioned and matched with the lower mold 3 for hitting the concave, and the machining accuracy is improved. The upper module 7 corresponds to the mol...

Abstract

The invention discloses a surface embossing process of a three-dimensional paper pulp molding product. The process specifically comprises the following steps: step 1, a paper pulp die is designed, a die body comprises an embossed upper die part and a debossed lower die part; the embossed upper die part and the debossed lower die part are respectively made of a male board and a female board which are matched with each other in high precision; the embossed upper die part is provided with an embossed upper die at an image-text processing part; the embossed shape of the image-text part after processing is converse to the image-text of a processed product; the debossed lower die part is provided with a debossed lower die at an image-text processing part; and the debossed shape of the image-textpart after processing is same with the image-text of the processed product. According to the invention, the specially customized paper pulp die is prepared. When the embossed upper die and the debossed lower die are in contact witha to-be-molded product, and pressing is carried out, embossing treatment is carried out on the surface of a paper-plastic product, and embossed patterns are generated on the surface of the product. The whole process technology is simple and practical, and the product has three-dimensional aesthetic appearance and is more attractive.

Description

technical field [0001] The invention relates to the field of post-processing technology of paper and plastic, in particular to a surface concave-convex technology of three-dimensional pulp molded products. Background technique [0002] The production process of molded products is as follows: pulp raw materials or plant fibers are formed by suction filtration in the suction filter forming device to make wet blanks of products, and the wet blanks are alternately sent to the left and right sides of the suction filter forming device. In the hot-pressing molds of the left hot-pressing setting device and the right hot-pressing setting device heated to a certain temperature, the hot-pressing molds of the left hot-pressing setting device or the right hot-pressing setting device are mold-closed and the wet billet is hot-pressed, dried and shaped. Pulp or plant fiber molded products into various shapes, this is the double heat press setting device mode of the manufacturing method of p...
