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 i...

preparation example Construction

[0039] The first embodiment of the preparation of the plate with three-dimensional graphics and text provided by the present invention includes steps:

[0040] Drawing the first prepolymer on the surface of the first part of the mold according to the first pattern to obtain the insert prepolymer;

[0041] curing the insert prepolymer on the surface of the template to obtain an insert on the surface of the template after curing;

[0042] assembling the first part of the mold with the insert with the second part of the mold into the mold;

[0043] Injecting a second prepolymer into the mold, the second prepolymer and the first prepolymer have a visual difference;

[0044] Curing the second prepolymer in the mold yields a panel with the insert.

[0045] According to the present invention, the resins used as the first prepolymer and the second prepolymer may be polyolefin resins, polyethylene resins, polystyrene resins, acrylic resins, fluororesins, polyamide resins, polycarbona...

Embodiment 1

[0095] Using acrylic resin as the material of the insert and the substrate, the board is prepared according to the following steps:

[0096] S101 prepares the opaque first prepolymer of following composition (by weight):

[0097] 100 parts of methyl methacrylate;

[0098] 0.12 parts of methacrylic acid as modifier;

[0099] 0.05 part of azobisisobutyronitrile as initiator;

[0100] 0.6 part of stearic acid as mold release agent;

[0101] 1 part of butyl phthalate as a plasticizer;

[0102] 0.6 part of divinylbenzene as crosslinking agent;

[0103] 1 part nano-titanium dioxide added to make the insert opaque;

[0104] S102 Send the first prepolymer into the glue dispenser, select 10mm thick tempered float glass as a template, and then draw the prepolymer on the glue dispenser according to the pattern program preset in the glue dispenser template, form figure 1 opaque insert 11 as shown;

[0105] S103 heating the first prepolymer on the surface of the template to 90°C fo...

Embodiment 2

[0115] Using acrylic resin as the material of the insert and the substrate, the board is prepared according to the following steps:

[0116] S101: Prepare an opaque first prepolymer of the following composition (by weight):

[0117] 100 parts of methyl methacrylate;

[0118] 0.12 parts of methacrylic acid as modifier;

[0119] 0.05 part of azobisisobutyronitrile as initiator;

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 ...
