[0025] like Figures 1-2 As shown, this embodiment of the present invention provides a tooling mold for polymer foaming and diffusion.

[0026] A tooling mold for polymer foaming and diffusion includes a first diffusion layer 1 and a second diffusion layer 2. The first diffusion layer 1 is detachably disposed on the second diffusion layer 2. A first partition plate 3 is disposed between the first diffusion layer 1 and the second diffusion layer 2. Both the first diffusion layer 1 and the second diffusion layer 2 include an outer plate 4 and a partition assembly 5. The partition assembly 5 divides the interior of the outer plate 4 into multiple chambers 6. Both the partition assembly 5 and the first partition plate 3 are provided with multiple through holes 7 to connect every two adjacent chambers 6. A top plate 8 is detachably disposed on the top of the first diffusion layer 1. The top plate 8 is provided with grouting holes 9, which are located on the top of the chambers 6.

[0027] This invention modularizes the overall structure by designing the mold as a detachable first diffusion layer 1 and second diffusion layer 2, with a first spacer 3 between them. This facilitates assembly, disassembly, and cleaning, effectively improving the mold's reusability and reducing experimental or trial production costs. Multiple through holes 7 are provided on the spacer assembly 5 and the first spacer 3 to connect adjacent chambers 6. By selectively blocking the through holes 7 at different locations, the flow path during polymer foaming can be flexibly controlled, thereby simulating various complex flow states and meeting experimental requirements under different process conditions.

[0028] It is understood that in some embodiments, a pressure sensor or a temperature sensor is installed in the through hole 7, which can detect relevant parameter information while sealing the through hole 7.

[0029] This embodiment describes a tooling mold for polymer foaming and diffusion. A plurality of first locking elements 10 are provided between the bottom of the outer wall of the first diffusion layer 1 and the top of the outer wall of the second diffusion layer 2, and a plurality of second locking elements 11 are provided between the top of the outer wall of the first diffusion layer 1 and the outer wall of the top plate 8. Specifically, by providing locking elements between the first diffusion layer 1 and the second diffusion layer 2, and between the first diffusion layer 1 and the top plate 8, the connection stability and sealing between the layers are improved, while facilitating quick assembly and disassembly, thus enhancing operational convenience and the overall structural reliability of the mold.

[0030] This embodiment describes a tooling mold for polymer foaming and diffusion, comprising a third diffusion layer 12, a second diffusion layer 2 detachably disposed on the third diffusion layer 12, and a second spacer 13 disposed between the second diffusion layer 2 and the third diffusion layer 12. The first diffusion layer 1, the second diffusion layer 2, and the third diffusion layer 12 include an outer peripheral plate 4 and a spacer assembly 5. The second spacer 13 has multiple through holes 7, and a bottom plate 14 is disposed at the bottom of the third diffusion layer 12. Specifically, adding the third diffusion layer 12 expands the overall cavity 6 structure of the mold, making the spatial dimensions of the simulated foaming process richer, enabling the simulation of multi-level flow paths, and improving the comprehensiveness and accuracy of experimental data.

[0031] Understandably, the number of diffusion layers can be increased according to the actual experimental needs.

[0032] In this embodiment, a tooling mold for polymer foaming and diffusion is provided, wherein multiple third locking elements 15 are provided between the bottom of the outer wall of the second diffusion layer 2 and the top of the outer wall of the third diffusion layer 12. Specifically, by providing third locking elements 15 between the second diffusion layer 2 and the third diffusion layer 12, the connection strength and sealing performance between the multi-layer structures are further enhanced, ensuring that the multi-layer structure is not prone to misalignment or leakage during use, and improving the overall stability and safety of the mold.

[0033] This embodiment describes a tooling mold for polymer foaming and diffusion. The partition assembly 5 includes six horizontal plates 16 and two vertical plates 17. The two vertical plates 17 are arranged parallel to each other in the vertical direction on the inner side of the outer perimeter plate 4. Horizontal plates 16 are arranged between the vertical plates 17 and the outer perimeter plate 4, and between the two vertical plates 17. The horizontal plates 16 are arranged in two parallel rows. Specifically, the partition assembly 5 forms a grid-like structure, i.e., it forms multiple regularly arranged chambers 6, which helps to evenly distribute the foaming material, enhances flow control, and thus improves foaming uniformity and molding quality.

[0034] It is understandable that the six horizontal plates 16, the two vertical plates 17, and the outer plate 4 are detachably connected by slots.

[0035] This embodiment describes a tooling mold for polymer foam diffusion, wherein all chambers 6 are cubic. Specifically, designing the chambers 6 as cubic structures facilitates a symmetrical and uniform flow field distribution, makes it easier to observe and analyze the diffusion behavior of the foaming material in different chambers 6, and improves the comparability and repeatability of experimental results.

[0036] The polymer foaming diffusion tooling mold described in this embodiment has nine through holes 7 between every two adjacent chambers 6, and the nine through holes 7 are distributed in a 3×3 array. Specifically, the nine through holes 7 arranged in a 3×3 array not only ensure effective communication between the chambers 6, but also provide diverse sealing options, facilitating precise control of the flow path of the foaming material and enhancing the flexibility and accuracy of process simulation.

[0037] It is understood that in some embodiments, the size of the through hole 7 can be adjusted according to the actual situation, and can be set to the same size or different sizes to simulate different flow conditions.

[0038] This embodiment describes a tooling mold for polymer foaming and diffusion. The first diffusion layer 1, the second diffusion layer 2, the third diffusion layer 12, the first spacer 3, the second spacer 13, the top plate 8, and the bottom plate 14 are all made of transparent acrylic sheets. Specifically, using transparent acrylic material for each component provides excellent visibility of the entire mold, facilitating real-time observation of the foaming process, recording bubble movement trajectories and material filling states, and aiding in in-depth research into the foaming mechanism and optimization of process parameters.

[0039] This embodiment describes a tooling mold for polymer foaming and diffusion. The top plate 8 is equipped with multiple plugs 18, each plug 18 having an injection hole 9. Each injection hole 9 corresponds one-to-one with a cavity 6. Specifically, this one-to-one correspondence between the injection holes 9 and the cavities 6 enables precise control of the raw material injection position, allowing for better control of the injected cavities 6 and simulating different paths. Other injection holes 9 not used for injecting foaming material can be plugged.
