Description

Technical Field

[0001] The utility model relates to the technical field of dipped cord fabric product detection, in particular to a novel stripping mould. Background Art

[0002] Dipped cord is widely used in the production of rubber products such as tires, conveyor belts and rubber tubes. The stripping detection technology of dipped cord is an important link in testing the bonding performance of dipped cord, which is mainly carried out through the stripping mold. In the traditional production of dipped cord, the vulcanization bonding performance test is a very important link, which directly affects the quality and performance of the product. In order to ensure that the vulcanization bonding performance of the dipped cord meets the requirements, vulcanization testing is required, which is mainly completed in the stripping mold. The traditional stripping mold for vulcanization testing is generally a single-cavity design, and double-sample comparison testing cannot be performed. In addition, some traditional molds have pads inside. Long-term use will cause the pads to wear and deform, resulting in uneven thickness of the vulcanized cord fabric and rubber vulcanization samples and inaccurate stripping force detection. The pad inside the mold expands due to heat at high temperature and is not easy to remove, so there are problems such as complicated operation.

[0003] Therefore, it is necessary to invent a novel stripping mold to solve the above problems. Utility Model Content

[0004] In order to solve the shortcomings of the prior art, the purpose of the utility model is to provide a new type of peeling mold, which solves the problem that the peeling molds used for testing in the prior art are generally single-cavity designs and cannot be used for double-sample comparison testing. In addition, some traditional molds use pads inside, which will cause the pads to wear and deform over a long period of time, resulting in uneven thickness of the vulcanized cord fabric and rubber vulcanization samples and inaccurate peeling force detection. The pads inside the mold expand due to heat at high temperatures and are difficult to remove, so there are problems such as complicated operation.

[0005] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0006] A novel peeling mold comprises a lower mold, a cover plate detachably covered on top of the lower mold, and a partition extending in the middle of the lower mold and dividing the lower mold into two equivalent cavities, and the lower mold and the partition are provided with glue guide and exhaust grooves around each cavity for guiding out bubbles and excess glue, and the two side walls of the lower mold are provided with openings for separating the cover plate and the lower mold at the position adapted to each cavity, and the top of the opening is an open end.

[0007] As a preferred solution of the utility model, mold ears are detachably threaded and penetrated at symmetrical positions of the lower mold and the two side walls of the cover plate.

[0008] As a preferred solution of the present invention, the depth of the cavity is 4.2 mm.

[0009] As a preferred solution of the utility model, the length, width and height of the opening are 30 mm, 10 mm and 4 mm respectively.

[0010] As a preferred solution of the utility model, the material of the lower mold and the cover plate is 3Cr2Mo high pressure and wear-resistant alloy steel.

[0011] As a preferred solution of the utility model, four glue-conducting and exhausting grooves surrounding the single cavity are connected to each other.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] In the utility model, the lower mold is divided into two equal cavities by a partition, thereby realizing a double-cavity design. In a single detection process of stripping the mold, the double-layer cord and rubber combined paving can be completed simultaneously in two independent but equal cavities, thereby completing the rubber coverage rate detection of the double-layer cord, that is, completing the comparison test of the same cord sample, different rubbers or different cord samples, the same rubber at the same temperature, pressure or time, thereby realizing double-sample comparative detection, detecting the difference in product adhesion performance under the same conditions, and reducing the amount of test rubber used to reduce waste. In the specific detection process, bubbles and excess glue are guided out through the glue guide exhaust groove to avoid the situation that the sample thickness does not meet the requirements due to bubbles or excess glue during the vulcanization process, thereby avoiding the problem that the subsequent sample is difficult to remove, and in the subsequent stripping process, the problem of being unable to open due to adhesion of the lower mold and the cover plate can be avoided by opening the mouth, which facilitates the separation of the lower mold and the cover plate and the removal of the internal sample.

[0018] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0019] The utility model provides Figure 1-Figure 2A new type of peeling mold shown in the figure includes a lower mold 1, a cover plate 2 detachably covered on the top of the lower mold 1, and a partition plate 3 extending in the middle of the lower mold 1 and dividing the lower mold 1 into two equivalent cavities 7, and the lower mold 1 and the partition plate 3 are provided with glue guide and exhaust grooves 5 around each cavity 7 for guiding out bubbles and excess glue, and openings 6 for separating the cover plate 2 and the lower mold 1 are provided at the positions of the two side walls of the lower mold 1 adapted to each cavity 7, and the top of the opening 6 is an open end, and the length and width of the base of the lower mold 1 and the cover plate 2 and the size of the cavity 7 can be determined according to the size of the test sample.

[0020] Symmetrical positions on both side walls of the lower mold 1 and the cover plate 2 are provided with mold ears 4 which are detachably threaded. The mold ears 4 can be used to facilitate different inspection operations on the lower mold 1 and the cover plate 2 and facilitate force bearing.

[0021] The depth of cavity 7 is 4.2mm. Compared with the traditional stripping mold with a depth of 2mm, the depth of cavity 7 of the new stripping mold is 4.2mm, which can complete the combined paving of double-layer cord and rubber, and facilitate double-sample comparison testing.

[0022] The length, width and height of the opening 6 are 30 mm, 10 mm and 4 mm respectively, and the opening 6 prevents the lower mold 1 from being stuck and unable to be opened after the rubber is vulcanized.

[0023] The material of the lower mold 1 and the cover plate 2 is 3Cr2Mo high-compression and high-wear-resistant alloy steel, and the surface of the lower mold 1 and the cover plate 2 is provided with a chrome-plated coating, and its Rockwell hardness can reach HRC24-28, thereby achieving the purpose of improving the wear resistance of the mold surface.

[0024] The four glue-conducting and exhausting grooves 5 surrounding the single cavity 7 are connected to each other.

[0025] In the utility model, the lower mold 1 is divided into two equal cavities 7 by the partition 3, thereby realizing the design of double cavity 7. In the single detection process of stripping the mold, the double-layer cord and rubber combination paving can be completed simultaneously in two independent but equal cavities 7, thereby completing the rubber coverage rate detection of the double-layer cord, that is, completing the comparison test of the same cord sample, different rubber or different cord samples, the same rubber at the same temperature, pressure or time, thereby realizing double-sample comparison detection, detecting the difference of product adhesion performance under the same conditions, and reducing the use of test rubber to reduce waste. In the specific detection process, bubbles and excess glue are guided out through the glue guide exhaust groove 5, avoiding the situation that the sample thickness does not meet the requirements due to bubbles or excess glue during the vulcanization process, thereby avoiding the problem that the subsequent sample is difficult to remove, and in the subsequent stripping process, the opening 6 can avoid the problem of being unable to open due to the adhesion of the lower mold 1 and the cover plate 2, which is convenient for the separation of the lower mold 1 and the cover plate 2, and the removal of the internal sample.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
