Description

Technical Field

[0001] The utility model belongs to the field of manufacturing electric vehicle and bicycle seats, and particularly relates to a 3D shaping mold inner compression molding mold. Background Art

[0002] With the improvement of material living standards, people's requirements for bicycle saddles are not only to meet the riding comfort, but also gradually shifted their focus to its appearance, requiring the saddle to have both comfort and an eye-catching appearance. Therefore, in order to meet market demand and attract more customers, saddle manufacturers have been working hard on the comfort and appearance of saddles. In addition to the conventional changes in shape and addition of color, setting a shape with a three-dimensional surface on the surface of the saddle is a common solution, that is, by setting a pattern with a three-dimensional surface on the surface of the saddle, it can relatively increase the breathability and comfort during riding, and also make the appearance of the saddle more unique. In the prior art, the conventional process for obtaining this three-dimensional effect is to perform high-frequency indentation treatment on the saddle leather surface. Although the saddle surface after high-frequency treatment will have a certain three-dimensional effect, this treatment process and the three-dimensional effect it brings have certain defects: first, during the skin climbing process, since the leather surface needs to be constantly pulled, it is easy to pull some three-dimensional parts into a plane due to excessive pulling, thereby affecting the formation of the three-dimensional effect; then, even if the three-dimensional effect of the leather surface is perfectly formed, it is easy to cause the three-dimensional effect of the leather surface to be slowly flattened until it disappears during the subsequent use of the saddle due to the rider's long-term riding or the application of certain external forces. Therefore, the three-dimensional effect formed by high-frequency indentation is more of a three-dimensional effect floating on the surface, which is greatly affected by the production process and subsequent external forces. Therefore, in order to make the three-dimensional effect of the saddle surface no longer affected by the production process and external forces, and to make the effect more three-dimensional, prominent and lasting, people hope to develop a new 3D shaping technology for the saddle surface. Utility Model Content

[0003] The utility model aims to provide a 3D shaping mold with a flexible use, which can quickly form a three-dimensional saddle surface, has a good three-dimensional effect, can maintain the three-dimensional effect for a long time, and can solve the problem that the old three-dimensional forming process of the saddle surface is poor in effect and not durable.

[0004] The utility model is realized by the following technical solutions:

[0005] The 3D shaping mold inner pressure molding mold includes a saddle molding upper mold and a saddle molding lower mold which can be used to first adsorb the saddle leather surface and then foam the leather surface to make a foaming layer. On the saddle molding lower mold, corresponding to the positions on the left and right sides of the leather surface where 3D shaping is required, two step-shaped grooves with a smaller upper part and a larger lower part are symmetrically dug. 3D shaping modules with shapes matching the step-shaped grooves can be detachably embedded in the two step-shaped grooves. The edges of the 3D shaping modules match the shape of the saddle molding lower mold to form a complete and smooth saddle. Only at the top corresponding to the positions on the left and right sides of the leather surface where 3D shaping is required, there are protrusions or depressions that can cooperate with the 3D shaping shape, so that when the foaming layer is formed, the leather surface and the foaming layer can be directly molded into the required 3D shaping structure together.

[0006] Preferably, the lower part of the 3D shaping module is supported by a fixing block, and the fixing block is fixed to the saddle forming lower mold by bolts.

[0007] Preferably, the protrusions or depressions on the 3D shaping module are right-angle structures at the edges and do not contain R angles, so as to make the shaping more three-dimensional.

[0008] Preferably, the protrusions or depressions are a protrusion or depression pattern structure. More preferably, the protrusions or depressions are a protrusion or depression stripe pattern structure, a dot pattern structure or a LOGO pattern structure.

[0009] Preferably, the leather surface is made of a highly plastic material to enhance the ductility and plasticity of the leather surface, thereby enabling a better 3D stereoscopic effect to be formed on the leather surface, and the three-dimensional effect of the saddle surface will not be destroyed by external forces such as squeezing and pulling during later use.

[0010] The beneficial effects of the utility model are:

[0011] The 3D shaping inner compression molding mold of the utility model has an ingenious structure, which makes the saddle surface 3D shaping molding technology more integrated and simple in its process. There is no need to first perform three-dimensional processing on the leather surface and then skin it. Instead, the three-dimensional effect is directly integrated with the leather surface, foaming, and mold into one. This not only greatly improves the overall production efficiency of the saddle, but also the molded 3D effect is more prominent and three-dimensional than before, and is no longer just floating on the surface, which greatly improves the recognition of the saddle's appearance and the breathability and comfort of riding. The mold itself can be flexibly replaced according to the pattern needs. It is easy to use, has low mold cost, and is highly practical, so it is worthy of promotion.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1-6 As shown, the 3D shaping mold inner pressure molding mold includes a saddle molding upper mold 1 and a saddle molding lower mold 2 which can be used to first adsorb the saddle leather surface and then foam the leather surface to make a foaming layer. On the saddle molding lower mold 2, corresponding to the positions on the left and right sides of the leather surface where 3D shaping is required, two step-shaped grooves 3 with a smaller upper part and a larger lower part are symmetrically dug. A 3D shaping module 4 with a shape matching the step-shaped groove 3 can be detachably embedded in the two step-shaped grooves 3. The edges of the 3D shaping modules 4 match the shape of the saddle molding lower mold to form a complete and smooth saddle. Only at the top corresponding to the positions on the left and right sides of the leather surface where 3D shaping is required, there are protrusions or depressions 5 that can cooperate with the 3D shaping shape, so that when the foaming layer is formed, the leather surface and the foaming layer can be directly formed into the required 3D shaping structure 6 together.

[0022] The remaining structures of the saddle molding upper mold 1 and the saddle molding lower mold 2 are the same as those of the existing saddle molding mold for foaming a foam layer on a leather surface.

[0023] The lower part of the 3D shaping module 4 is supported by a fixing block 7 , and the fixing block 7 is fixed to the saddle forming lower mold 2 by bolts 8 . The fixing block 7 is also located in the stepped groove 3 .

[0024] The protrusions or depressions 5 on the 3D shaping module 4 are right-angle structures at the edges and do not contain R angles, so as to make the shaping more three-dimensional.

[0025] The leather surface is made of highly plastic material.

[0026] The protrusions or depressions 5 are a pattern structure of protrusions or depressions. In this embodiment, the pattern structure is parallel strip-shaped protrusions.

[0027] Production process: put the leather surface into the lower mold for vacuum shaping and finalization, then inject the foaming material and close the mold to form.

[0028] The saddle product produced in this embodiment is as follows Figure 6 As shown, it can be seen from the saddle that the leather surface and the left and right sides of the foam layer below it have a number of strip-shaped 3D shaping structures that are recessed downwards, and the structure is formed by the presence of the protrusions on the 3D shaping module 4.

[0029] The utility model directly designs the three-dimensional pattern in the mold, so that the three-dimensional pattern, the leather surface, and the foaming can be formed in one piece through the mold. It can perfectly replace the treatment method of only performing high-frequency indentation on the leather surface, which only shows the three-dimensional effect floating on the surface, making the 3D effect on the saddle surface more prominent and three-dimensional, and also solves the problem that the original method will affect the three-dimensional effect due to pulling during the skin climbing process. In addition, when the convexity or concaveness on the 3D shaping module is designed to be a right-angle structure at the edge without an R angle, the three-dimensional sense of the molding can be stronger, further ensuring a better three-dimensional molding effect.

[0030] The 3D shaping inner compression molding mold of the utility model has an ingenious structure, which makes the saddle surface 3D shaping molding technology more integrated and simple in its process. There is no need to first perform three-dimensional processing on the leather surface and then skin it. Instead, the three-dimensional effect is directly integrated with the leather surface, foaming, and mold into one. This not only greatly improves the overall production efficiency of the saddle, but also the molded 3D effect is more prominent and three-dimensional than before, and is no longer just floating on the surface, which greatly improves the recognition of the saddle's appearance and the breathability and comfort of riding. The mold itself can be flexibly replaced according to the pattern needs. It is easy to use, has low mold cost, and is highly practical, so it is worthy of promotion.

[0031] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
