Technical Field

[0001] The utility model relates to the technical field of in-mold injection molding, in particular to an in-mold injection molding surface micro-structure texture forming device. Background Technique

[0002] In the in-mold injection molding technology, by directly forming decorative patterns or functional patterns inside the mold together with the plastic substrate, not only the aesthetics and functionality of the product are improved, but also the production process is greatly simplified and the production cost is reduced.

[0003] When performing in-mold injection molding, it is necessary to add micro-structure textures to the injection molding surface to improve the ornamental value or feel. When the existing in-mold injection molding surface micro-structure texture forming device is used, generally, after pasting the mold sheet printed with textures on the mounting rack, the mounting rack is installed in the mold. However, this installation method is not convenient for disassembling and replacing the mold sheet. Therefore, it is necessary to provide an in-mold injection molding surface micro-structure texture forming device that is convenient for replacing the mold sheet. Summary of the Utility Model

When the existing in-mold injection molding surface micro-structure texture forming device is used, generally, after pasting the mold sheet printed with textures on the mounting rack, the mounting rack is installed in the mold. However, this installation method is not convenient for disassembling and replacing the mold sheet.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an in-mold injection molding surface micro-structure texture forming device, including:

[0007] A texture forming mechanism, the texture forming mechanism includes a mold sheet, the outer wall of the mold sheet is printed with textures, three limiting pieces are fixedly connected to the outer wall of the side of the mold sheet, a mounting rack is placed on the outer wall of the mold sheet, a connecting rack is fixedly connected to the outer wall of the mounting rack, and a limiting groove is opened on the outer wall of the mounting rack.

[0008] Further, five fixing blocks are fixedly connected to the inner wall of the limiting groove, and the limiting piece is located between two of the fixing blocks;

[0009] Further, a movable plate is slidably connected to the inner wall of the limiting groove, and limiting holes are symmetrically opened on the outer wall of the movable plate.

[0010] Further, limiting rods corresponding to the limiting holes are symmetrically threadedly connected to the outer wall of the end of the connecting rack.

[0011] Further, a limiting mechanism is further included. The limiting mechanism includes mounting holes symmetrically formed in the outer wall of the mounting frame away from the die plate side, and a first spring is fixedly connected to the inner wall of the mounting hole.

[0012] Further, a connecting cylinder is fixedly connected to the outer wall of the end of the first spring, and a through hole is formed through the end of the connecting cylinder.

[0013] Further, a limiting ball is movably connected to the inner wall of the through hole, and a second spring is fixedly connected between the two limiting balls.

[0028] Please refer to Figures 1 - 3 As shown, this embodiment is an in-mold injection molding device for forming surface micro-structure textures, including:

[0029] A texture forming mechanism, which includes a die piece 101. The outer wall of the die piece 101 is printed with a texture 102. Three limiting pieces 103 are fixedly connected to the outer wall of the side of the die piece 101. A mounting frame 104 is placed on the outer wall of the die piece 101. A connecting frame 105 is fixedly connected to the outer wall of the mounting frame 104. A limiting groove 106 is opened on the outer wall of the mounting frame 104. The limiting pieces 103 are in full contact with the inner wall of the limiting groove 106;

[0030] The surface is textured during injection molding through the texture 102 of the mold piece 101. The mold piece 101 is preliminarily positioned by inserting the limit piece 103 into the limit groove 106. The mold piece 101 is supported by the mounting bracket 104 and installed in the mold. The mold piece 101 is positioned again by the connecting bracket 105;

[0031] Five fixing blocks 107 are fixedly connected to the inner wall of the limit groove 106, and the limit piece 103 is located between two fixing blocks 107;

[0032] The connecting bracket 105 is supported by the fixing block 107;

[0033] The inner wall of the limit groove 106 is slidably connected with a movable plate 108. Limiting holes 109 are symmetrically opened on the outer wall of the movable plate 108. Limiting rods 110 corresponding to the limiting holes 109 are symmetrically and threadedly connected to the outer wall of the end of the connecting bracket 105;

[0034] The mold piece 101 is finally positioned by the movable plate 108, and the movable plate 108 is positioned by installing the limiting rod 110 in the limiting hole 109;

[0035] Working principle: Remove the limiting rod 110. After pulling out the movable plate 108 from the limit groove 106, place the mold piece 101 printed with the texture 102 inside the inner wall of the connecting bracket 105, insert the limit piece 103 into the limit groove 106, insert the movable plate 108 into the limit groove 106. After the movable plate 108 is in full contact with the mold piece 101, insert the limiting rod 110 into the limiting hole 109 to position the movable plate 108;

[0036] In this step, the mold piece 101 can be installed on the inner wall of the connecting bracket 105, which is convenient for replacing the mold piece 101.

[0037] Please refer to Figures 1 - 3 As shown, on the basis of the above-mentioned Embodiment 1, this embodiment further includes:

[0038] A limiting mechanism. The limiting mechanism includes mounting holes symmetrically opened on the outer wall of the mounting bracket 104 away from the mold piece 101. A first spring 203 is fixedly connected to the inner wall of the mounting hole;

[0039] The first spring 203 is supported by the mounting hole;

[0040] A connecting cylinder 201 is fixedly connected to the outer wall of the end of the first spring 203. A through hole 202 is penetrated and opened at the end of the connecting cylinder 201;

[0041] The connecting cylinder 201 is inserted into the corresponding hole of the mold by the rebound of the first spring 203;

[0042] The inner wall of the through hole 202 is movably connected with a limiting ball 205, and a second spring 204 is fixedly connected between the two limiting balls 205;

[0043] The second spring 204 rebounds to make the limiting ball 205 extend out of the through hole 202 and contact the inner wall of the corresponding hole;

[0044] Working principle: When the whole device is installed in the mold, the mounting frame 104 is brought close to the inner wall of the mold, so that the inner wall of the mold pushes the connecting cylinder 201 and compresses the first spring 203. Moving the mounting frame 104 drives the connecting cylinder 201 to move. When it moves to the corresponding hole on the inner wall of the mold, the first spring 203 rebounds to make the connecting cylinder 201 insert into the corresponding hole. The inner wall of the corresponding hole pushes the limiting ball 205 and compresses the second spring 204. The second spring 204 rebounds to make the limiting ball 205 fully contact the inner wall of the corresponding hole;

[0045] This step can quickly limit the whole device.
