Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an injection mold for a tissue box. Background Art

[0002] As a convenient storage device that can effectively protect tissues from external pollution, tissue boxes have been widely used in modern life. Fig.10 As shown, there is a tissue box design 10 currently on the market, and its main structure includes two parts: an upper shell and a lower shell. The two parts are integrally formed on one side, and the other side is detachably connected through the design of a clever buckle structure 10a, 10b, providing a convenient user experience. However, there is a technical challenge in the production process of this tissue box. Because its buckle structure radially protrudes from the shell, when the injection mold is used for product molding, the buckle part will be radially embedded in the mold. This phenomenon significantly increases the difficulty of demolding the tissue box, which not only affects production efficiency, but may also have an adverse effect on product quality.

[0003] In order to solve this problem, the existing injection mold needs to be improved to solve the demoulding problem of the buckle structure, thereby reducing the production difficulty and improving product quality, while maintaining the original design and ease of use of the tissue box. Utility Model Content

[0007] Compared with the prior art, the injection mold of the utility model is specially designed with an exhaust channel, which is connected to the molding groove. When demolding, the molding groove jet can help the buckle part of the product to be more easily detached from the mold, significantly reducing the difficulty of demolding. Due to the reduction in the difficulty of demolding, a key link in the production process is optimized, thereby improving the overall production efficiency, and the demolding process will not cause the product to be damaged during the demolding process, affecting the product quality, thereby improving the overall quality of the product. In addition, the utility model is aimed at the mold design in the production process, and does not change the design of the tissue box itself, so users can still enjoy the original convenience when using the tissue box.

[0008] Furthermore, the template is provided with mounting holes running longitudinally through both ends thereof and modules arranged in the mounting holes, the molding groove is arranged on the upper side of the module, and a part of the exhaust channel is arranged in the module. This solution realizes the modular design of the mold by arranging mounting holes and detachable modules on the template. This design makes the mold more flexible, and the modules can be quickly replaced or adjusted as needed to meet the production requirements of tissue boxes with different buckle shapes or sizes. At the same time, the modular design makes the maintenance and repair of the mold easier.

[0009] Furthermore, the fixed mold is provided with a fixing block at the bottom of the template, and the fixing block abuts against the lower side of the module, and the fixing block is fixed to the template by a bolt structure. This solution uses a bolt structure to connect the fixing block and the template, making the adjustment and maintenance of the mold more convenient. When the module needs to be replaced, the corresponding operation can be performed by simply loosening the bolts. In addition, the bolt connection also facilitates rapid disassembly and maintenance when the mold is worn or fails.

[0010] Furthermore, the exhaust channel includes an input channel, an output channel and a second exhaust hole, the input channel is radially arranged at the bottom of the template, the output channel longitudinally runs through both ends of the template to connect the input channel and the first molding area, and the second exhaust hole is radially connected between the molding groove and the output channel.

[0011] Furthermore, a first exhaust hole is provided at the upper part of the output channel, and the output channel is connected to a second exhaust hole through the first exhaust hole, and the diameter of the first exhaust hole is smaller than the lower part of the output channel. In this solution, the first exhaust hole is provided at the upper part of the output channel, which has a compressing effect on the airflow entering the output channel, thereby increasing the pressure and effectively assisting the demoulding of the tissue box.

[0012] Furthermore, the first exhaust holes are evenly arranged in the first shaping area. This solution assists in demoulding the tissue box as a whole by evenly arranging the first exhaust holes in the first shaping area.

[0013] Furthermore, the input channel is a mesh structure. The design of the mesh structure can increase the number and distribution density of the output channels.

[0014] Furthermore, the input channel includes a plurality of branch airways, and the branch airways are arranged in a crisscross manner.

[0015] Furthermore, the first exhaust holes are arranged in a matrix.

[0016] Furthermore, the modules are provided in two opposite groups. BRIEF DESCRIPTION OF THE DRAWINGS
