Method for preparing plates with three-dimensional images and texts and computer

Abstract

The invention discloses a method for preparing plates with three-dimensional images and texts, which comprises the steps of: drawing a first prepolymer according to a first image on the surface of the first part of a mould to obtain an insert prepolymer; solidifying the insert prepolymer on the surface of a template to obtain an insert on the surface of the template after solidification; assembling the first part of the mould with the insert and the second part of the mould into the mould; injecting a second prepolymer into the mould, wherein the second prepolymer and the first prepolymer have the visual effect difference; and solidifying the second prepolymer in the mould to obtain the plates with the insert. Compared with the prior art, the invention has the advantages that the cost is beneficial to being reduced because the preparation working procedure of the mould with the insert is saved; the insert prepolymer is drawn on the surface of the template after being solidified; and the problems of difficult accurate positioning and fixing of mass separation components in the course of the casting of the insert or the injection molding of the insert.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a method and a computer for preparing plates with three-dimensional graphics and text. Background technique [0002] In order to meet the requirements of various purposes such as decoration and warning, it is necessary to prepare three-dimensional graphics in the board. For example, when preparing some warning signs, it is necessary to provide a board with a flat surface, and there are warning signs inside the board, which can enhance the visual effect. [0003] In the prior art, there are mainly two methods of insert casting and insert injection molding when preparing a plate with three-dimensional graphics. In the insert casting method, the main process steps are: a) First prepare the prototype of the insert, and use the prototype to turn out the mold for forming the insert (if the insert is relatively simple, it can also be directly prepared by means such as CNC machining ...

AI Technical Summary

Problems solved by technology

[0004] Adopting the insert casting method has the following disadvantages: 1) It is necessary to prepare a mold according to the insert every time. Because the cost of the mold is relatively high, this method is only suitable for the production of large quantities of three-dimensional graphic products of a single variety, and is not suitable for small production quantities. Variety of three-dimensional graphic products

2) Due to the complicated and cumbersome production of inserts, especially when the inserts include a large number of fine and discrete components, the process of making inserts is more cumbersome and reduces work efficiency

3) When fixing the insert in the mold of the three-dimensional graphic product, in order to prevent the insert from sliding or shifting, more or less fixed marks will be left on the insert, which affects the quality of the final product

4) It is difficult to position the insert in the mold, especially when the insert includes a large number of finely divided and discrete components, it is difficult to accurately position the components

[0006] Considering the above shortcomings in the prior art, there is a need for a method for preparing plates with three-dimensional graphics that is simple in process, can reduce costs, and solve the problem of inserts being difficult to accurately position on the mold
