Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a blind spot injection mold. Background Art

[0002] IMD is a technology that places the printed decorative sheet into the injection mold, then injects the resin on the back of the molded sheet to make the resin and the sheet bonded together and solidify. IMD is a technology that adds decoration while injection molding. The product is laminated with the decorative printing material as a whole. The entire three-dimensional molded product can be decorated and printed, making the product both decorative and functional.

[0003] As shown in the attached figure of the instruction manual Figure 4-Figure 6 As shown, 1' is a fixed mold, 2' is a sheet, and 201' is a blind spot. The sheet can increase the feel of the key by adding a blind spot. Since the blind spot 201' is a long strip, the fixed mold 1' can only be heated or cooled as a whole and cannot control the temperature locally. The blind spot 201' area cannot obtain a certain temperature, resulting in insufficient ink temperature on the blind spot 201' area. When the ink and the blind spot 201' are shaped, the root of the blind spot 201' is easily fractured, causing light transmission and resulting in product scrapping, thereby affecting the yield and production output.

[0004] Therefore, further improvement is needed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a blind spot injection mold to overcome the shortcomings of the prior art. A water supply for the blind spot is set on the fixed mold, which can effectively reduce the occurrence of cracks at the blind spot and improve the product yield and production output.

[0006] A blind spot injection mold designed for this purpose includes a fixed mold on which a sheet can be placed, the fixed mold is provided with a blind spot area that cooperates with the sheet, the fixed mold is provided with an independently arranged first heating and water transporting structure, the first heating and water transporting structure is located on the blind spot area, and hot water heats the blind spot area through the first heating and water transporting structure.

[0007] The first heating water transport structure includes a first heating section, and the first heating section is transversely arranged on the blind spot area.

[0008] The heating length of the first heating section is greater than the blind spot area.

[0009] The distance between the first heating section and the sheet is b, 1mm≤b≤30mm.

[0010] The first heating water transport structure also includes a hot water inlet section and a first connecting section. The hot water inlet section is connected to one end of the first heating section through the first connecting section. The first connecting section is vertically arranged between the hot water inlet section and the first heating section.

[0011] The first heating water transport structure further includes a hot water outlet section and a second connecting section. The hot water outlet section is connected to the other end of the first heating section through the second connecting section.

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0022] like Figure 1-Figure 3 As shown, a blind spot injection mold is provided, including a fixed mold 1 on which a sheet a can be placed, a blind spot area 101 cooperating with the sheet a is provided on the fixed mold 1, and an independently arranged first heating water transport structure 2 is provided on the fixed mold 1. The first heating water transport structure 2 is located on the blind spot area 101, and hot water heats the blind spot area 101 through the first heating water transport structure 2.

[0023] Specifically, the blind spot area 101 on the fixed mold 1 cooperates with the shape of the sheet a, so that the blind spot area 101 can be properly heated; the independently arranged first heating water transport structure 2 can independently control the heating of the ink on the blind spot area 101, ensuring the accuracy and uniformity of the heating; after the sheet a is placed in the mold, it must be heated to a certain extent to soften the local ink part at the position of the blind spot area 101 first, so that the sheet a and the ink are more curved to shape the blind spot. After the cavity injection molding is completed, the first heating water transport structure 2 stops heating, the cooling water transport is turned on, and the first heating water transport is turned on after the mold is opened, which can effectively reduce the occurrence of cracks and light transmission at the blind spots on the sheet a, and improve the product yield and production output.

[0024] Further, if Figure 1 and Figure 3 As shown, the first heating water transport structure 2 includes a first heating section 201 , and the first heating section 201 is transversely arranged on the blind spot area 101 .

[0025] Specifically, the first heating section 201 is horizontally arranged on the blind spot area 101, which can ensure that the blind spot area 101 is evenly heated during the heating process, avoid quality problems caused by uneven heating, and improve the overall quality of the product.

[0026] Further, if Figure 1 and Figure 3 As shown, the heating length of the first heating section 201 is greater than the blind spot area 101 .

[0027] Specifically, the heating length of the first heating section 201 is greater than the blind spot area 101, which can ensure that the heating length of the first heating section 201 is large enough to cover the blind spot area 101, and can ensure that the blind spot area 101 can be maintained within an appropriate temperature range during the entire heating process, avoiding quality problems caused by uneven temperature.

[0028] Further, if Figure 2 As shown, the distance between the first heating section 201 and the sheet a is b, 1mm≤b≤30mm.

[0029] Specifically, the distance a is the heat transfer between the first heating section 201 and the sheet a. If the distance a is too large, the heat transfer speed between the first heating section 201 and the sheet a may be reduced, affecting the heating effect; if the distance a is too small, the heat transfer speed between the first heating section 201 and the sheet a may be too fast, and all areas of the sheet may not be fully covered and heated;

[0030] Preferably, the distance a is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, or 30 mm.

[0031] Further, if Figure 1 and Figure 3 As shown, the first heating water transport structure 2 also includes a hot water inlet section 202 and a first connecting section 203. The hot water inlet section 202 is connected to one end of the first heating section 201 through the first connecting section 203. The first connecting section 203 is vertically arranged between the hot water inlet section 202 and the first heating section 201.

[0032] Specifically, the first connecting section 203 is vertically arranged between the hot water inlet section 202 and the first heating section 201, and plays the role of connecting the two parts. Through the hot water inlet section 202, high-temperature hot water can be provided to the first heating section 201, thereby heating the ink.

[0033] Further, if Figure 1 and Figure 3As shown, the first heating water transport structure 2 also includes a hot water outlet section 204 and a second connecting section 205. The hot water outlet section 204 is connected to the other end of the first heating section 201 through the second connecting section 205. The second connecting section 205 is vertically arranged between the hot water outlet section 204 and the first heating section 201.

[0034] Specifically, the hot water inlet section 202, the first connecting section 203, the hot water outlet section 204, the second connecting section 205 and the first heating section 201 constitute an integral first heating water transport structure 2; hot water can be smoothly transferred from the first heating section 201 to the second connecting section 205, and then discharged through the hot water outlet section 204.

[0035] Further, if Figure 2 As shown, the fixed mold 1 is also provided with a second heating and water transporting structure 3 for synchronous heating, and the second heating and water transporting structure 3 is arranged around the sheet a.

[0036] Specifically, the second heating water transport structure 3 is used to provide a more uniform heat distribution for the sheet a, so as to improve the processing accuracy and efficiency of the sheet a, so that the sheet a is always kept in a relatively stable temperature environment during the entire processing process, which is beneficial to improving the quality of the sheet a.

[0037] Further, if Figure 1 As shown, the first heating water transportation structure 2 and the second heating water transportation structure 3 are not connected to each other.

[0038] Specifically, the first heating water transport structure 2 and the second heating water transport structure 3 can work independently to achieve a heating effect on the entire processing area.
