Description

Technical Field

[0001] This utility model relates to the field of diaper production equipment, specifically to a mold used in diaper production. Background Technology

[0002] With the rapid development of the disposable hygiene products industry, diapers, as an important product in the field of infant and adult care, have seen their production efficiency and quality stability become core elements of corporate competitiveness. Currently, the molding process for diaper cores generally uses hot-press molds to compress and shape the fluffy core material. The rationality of the mold structure directly affects the molding accuracy, production efficiency, and equipment maintenance costs of the core.

[0003] In existing technologies, diaper core forming molds typically consist of an upper mold and a lower mold, with the lower mold having a fixed forming cavity. The upper and lower molds are closed by hydraulic or pneumatic drive. However, in traditional molds, the forming cavity and the lower mold are integrally formed. When it is necessary to change to a core of different specifications (such as thickness or shape), the entire lower mold must be replaced. Since there is a hydraulic or pneumatic drive device between the upper and lower molds, installation and disassembly are cumbersome, resulting in long changeover times and seriously affecting the continuous operation efficiency of the production line. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a mold for the production of diapers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mold for diaper production, comprising a mold body, a forming component, a lifting device, and a quick assembly / disassembly device. The mold body includes an upper mold and a lower mold. The upper mold is disposed on the lower mold, and the lower mold has an installation cavity. The forming component is detachably disposed in the installation cavity, and the forming component has a forming cavity adapted to the diaper core. The lifting device is disposed between the upper mold and the lower mold to drive the upper mold to move up and down so that the upper mold and the lower mold can be closed or separated. The quick assembly / disassembly device is disposed between the forming component and the lower mold to quickly install or remove the forming component from the lower mold.

[0006] Furthermore, the lifting device includes an electric push rod and a connecting member. The electric push rod is disposed on the lower mold, one end of the connecting member is connected to the electric push rod, and the other end of the connecting member is connected to the upper mold.

[0007] Furthermore, the lifting device comprises two sets, which are arranged symmetrically.

[0008] Furthermore, the quick assembly / disassembly device includes a positioning mechanism and a magnetic attraction mechanism. Both the positioning mechanism and the magnetic attraction mechanism are disposed between the molded part and the lower mold. The positioning mechanism is used to position the molded part, and the magnetic attraction mechanism is used to attract and fix the molded part onto the lower mold.

[0009] Furthermore, the positioning mechanism includes a positioning post and a positioning hole. The positioning post is disposed on the molded part, the positioning hole is disposed on the lower mold, and the positioning post is installed in the positioning hole.

[0010] Furthermore, the end of the positioning post is provided with an inverted conical structure.

[0011] Furthermore, the magnetic attraction mechanism includes a first magnet and a second magnet. The first magnet is disposed on the lower mold, and the second magnet is disposed on the molded part. The first magnet and the second magnet attract each other to attract and fix the molded part to the lower mold.

[0012] Furthermore, the cavity wall of the molding cavity is provided with an anti-corrosion structure, which includes a polytetrafluoroethylene layer, an epoxy resin layer, an acrylic paint layer and a polyurethane coating arranged sequentially from top to bottom.

[0013] As can be seen from the above description of the present invention, compared with the prior art, the mold for diaper production provided by the present invention has the following advantages: the molding part and the lower mold adopt a detachable connection structure, and with the quick disassembly and assembly device, the molding part can be quickly replaced without disassembling the upper mold and the lifting device. Therefore, when it is necessary to replace the cotton core of diapers of different specifications, only the molding part needs to be replaced, without replacing the entire lower mold, which greatly shortens the changeover time and improves the continuous operation efficiency of the production line.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] Reference Figures 1-5 As shown, a mold for diaper production includes a mold body 1, a forming component 2, a lifting device 3, and a quick-assembly / disassembly device 4. The mold body 1 includes an upper mold 11 and a lower mold 12. The upper mold 11 is disposed on the lower mold 12, and the lower mold 12 has an installation cavity 121. The forming component 2 is detachably disposed in the installation cavity 121, and the forming component 2 has a forming cavity 21 adapted to the diaper core. The lifting device 3 is disposed between the upper mold 11 and the lower mold 12 to drive the upper mold 11 to move up and down so that the upper mold 11 and the lower mold 12 can be closed or separated. The quick-assembly / disassembly device 4 is disposed between the forming component 2 and the lower mold 12 to quickly install or remove the forming component 2 from the lower mold 12. Thus, when it is necessary to change diaper cores of different specifications, only the forming component 2 needs to be replaced, without replacing the entire lower mold 12, which greatly shortens the changeover time and improves the continuous operation efficiency of the production line.

[0021] The lifting device 3 includes two sets, which are symmetrically arranged to ensure smooth lifting of the upper mold 11. Each lifting device 3 includes an electric push rod 31 and a connecting member 32. The electric push rod 31 is mounted on the lower mold 12, one end of the connecting member 32 is connected to the electric push rod 31, and the other end of the connecting member 32 is connected to the upper mold 11.

[0022] The quick assembly / disassembly device 4 includes a positioning mechanism 41 and a magnetic attraction mechanism 42. Both the positioning mechanism 41 and the magnetic attraction mechanism 42 are disposed between the molded part 2 and the lower mold 12. The positioning mechanism 41 is used to position the molded part 2, and the magnetic attraction mechanism 42 is used to attract and fix the molded part 2 onto the lower mold 12.

The first magnet 421 is disposed on the lower mold 12, and the second magnet 422 is disposed on the molded part 2. The first magnet 421 and the second magnet 422 attract each other to attract and fix the molded part 2 on the lower mold 12, ensuring the stability of the molded part 2 during the molding process, and also facilitating the disassembly of the molded part 2.

[0025] The cavity wall of the molding cavity 21 is provided with an anti-corrosion structure 5, which includes a polytetrafluoroethylene layer 51, an epoxy resin layer 52, an acrylic paint layer 53 and a polyurethane coating 54 arranged sequentially from top to bottom. Each layer is compounded by spraying or impregnation process, which has excellent high temperature resistance and corrosion resistance, effectively improves the anti-corrosion performance of the molding cavity 21, extends the service life of the mold, and ensures the stability of product quality.

[0026] In use, according to the required specifications of the diaper core, the corresponding molded part 2 is installed into the mounting cavity 121 of the lower mold 12 using the quick-release device 4. The positioning pin 411 is inserted into the positioning hole 412 for positioning, and the first magnet 421 and the second magnet 422 attract each other to fix the molded part 2. Then, the electric push rod 31 in the lifting device 3 drives the upper mold 11 to descend through the connecting piece 32, closing with the lower mold 12 to compress and shape the core material. When it is necessary to change the core specification, the electric push rod 31 drives the upper mold 11 to rise, separating the upper mold 11 and the lower mold 12. Then, the molded part 2 is removed from the mounting cavity 121 and replaced with a new molded part 2.

[0027] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
