Technical Field

[0001] This invention relates to the field of mold technology, specifically a conformal flow channel coating integral molding mold. Background Technology

[0002] Integrated film coating technology is widely used in shoe soles, decorative parts and other fields. Its core lies in molding the surface coating and the base material in one step in the mold to improve the product's aesthetics and integrity. Existing molds are mostly made of single materials or conventional processing methods, which makes it difficult to achieve conformal flow channel design and precise temperature control. Therefore, a mold system that integrates film coating fixation, vacuum adsorption, conformal flow channels and multi-mold collaboration is needed to improve the automation level, molding speed and product consistency of shoe sole molding.

[0003] While existing conformal flow channel technology improves heat exchange by fitting the flow channel to the cavity, it still uses a uniform medium circulation and cannot actively form the required dynamic temperature gradient according to the thickness of different areas and the shrinkage characteristics of the material during the molding process, which makes the product prone to defects such as warping and shrinkage marks.

The embodiments of this invention will now be described according to its overall structure.

[0026] Example 1:

[0027] Please see Figures 1-3 The present invention discloses a conformal flow channel coating integral molding mold, including a mold body, which is composed of three parts: a lower mold 1, a middle frame 2, and an upper mold 3. The middle frame 2 and the lower mold 1 are combined by a hinge 15 to realize the rotation opening and closing action of the mold. The bottom of the lower mold 1 and the bottom of the upper mold 3 are respectively provided with a lower mold base fixing hole 13 and an upper mold base fixing hole 26. The lower mold 1 and the upper mold 3 are respectively fixed on the production machine through the lower mold base fixing hole 13 and the upper mold base fixing hole 26 to realize the up and down movement opening and closing action of the mold. The lower mold base fixing hole 13 and the upper mold base fixing hole 26 facilitate fixation with the production machine.

[0028] The lower mold 1 is provided with a lower mold sealing ring 10, a lower mold cavity 11, a lower mold pin 12 that corresponds to and matches the mold closing and positioning of the middle frame 2, a lower mold vacuum hole 14, a hidden venting groove 5, a lower mold flow channel 9, and a lower mold fixing buckle 23. The lower mold sealing ring 10 facilitates a tight seal with the film to achieve a sealed state between the film and the lower mold cavity 11.

[0029] The middle frame 2 is provided with a stroke spring 16 for controlling the closing of the upper mold 3, a middle frame sealing ring 17, a middle frame venting groove 18, a folding Z-shaped sealing ring 6, a venting groove 8, a middle frame fixing mold block 19 that corresponds to the closing and positioning of the lower mold 1 and the upper mold 3, a middle frame fixing mold nail hole 20, an automatic lock 21, and a handle 22. The upper mold 3 is provided with an upper mold cavity 25, an upper mold fixing mold block 24 that corresponds to the closing and positioning of the middle frame 2, an upper mold fixing mold nail 27, an upper mold vacuum hole 28, a hidden venting groove 5, and an upper mold flow channel 4. The upper mold flow channel 4 and the lower mold flow channel 9 facilitate the passage of steam, room temperature water, and ice water required for shoe sole molding.

[0030] An O-ring 7 is provided at the connection between the lower mold 1 and the middle frame 2. The upper mold flow channel 4 and the lower mold flow channel 9 are set with relevant positions, shapes and sizes through CAE simulation analysis. The mold body is realized by casting, CNC machining and 3D printing.

[0031] The lower mold vacuum hole 14 and the upper mold vacuum hole 28 are connected to the invisible venting groove 5 to realize the gas discharge between the film and the cavity.

[0032] The folded Z-shaped sealing ring 6 on the middle frame 2 works in conjunction with the travel spring 16 to form a sealed area when the upper mold 3 is closed.

[0033] The automatic locking buckle 21 cooperates with the lower mold fixing locking buckle 23 to fix the film after the middle frame 2 and the lower mold 1 are closed.

[0034] The working principle of the conformal flow channel coating integral molding die based on Embodiment 1 is as follows:

[0035] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0036] Second, the worker places the finished product to be molded on the parting surface between the middle frame 2 and the lower mold 1. After the middle frame 2 is closed, the film is fixed to the lower mold by the automatic locking buckle 21 and the fixing locking buckle 23. The sealing ring 10 of the lower mold is tightly sealed with the film, so that the film and the lower mold cavity 11 are in a sealed state. The gas in the sealed area between the film and the lower mold cavity 11 is discharged through the vacuum hole 14 of the lower mold by the negative pressure through the invisible exhaust groove 5, so that the film is completely bonded to the lower mold cavity 11. Then the worker places the rough blank to be molded into the lower mold cavity 11 after the negative pressure film is applied. The upper mold 3 is connected by a stroke spring. The 16 and folded Z-shaped sealing ring 6 form a certain sealed area with the blank in the lower mold cavity 11. The gas in the sealed area is discharged through the vacuum hole 28 of the upper mold through the invisible exhaust groove 5 and the middle frame exhaust groove 18, thereby maintaining a vacuum state in the lower mold cavity 11 and the upper mold cavity 25. Then, the lower mold 1 and the upper mold 3 are pressurized by the machine to achieve mold closing. Finally, the steam, room temperature water and ice water required for shoe sole molding are circulated through the upper mold flow channel 4 and the lower mold flow channel 9 to obtain the rapidly molded shoe sole product, improving the automation level, molding speed and product consistency of shoe sole molding.

[0037] Example 2:

[0038] Please see Figures 4-5 The conformal flow channel coating integral molding mold of the present invention, compared with the first embodiment, further includes: an upper mold flow channel 4, both the upper mold flow channel 4 and the lower mold flow channel 9 are composed of a first flow channel branch 91, a second flow channel branch 92, a first solenoid valve 93, a second solenoid valve 94, a thermal barrier layer 95, and a thermal diffusion insert 96. The first solenoid valve 93 and the second solenoid valve 94 are fixedly connected at the conveying ports of the first flow channel branch 91 and the second flow channel branch 92, respectively.

[0039] Both the first flow channel branch 91 and the second flow channel branch 92 are fixedly connected to a thermal barrier layer 95, and an electric heating coil for auxiliary heating is provided between the two sets of thermal barrier layers 95. Both the first flow channel branch 91 and the second flow channel branch 92 are provided with a heat diffusion insert 96 at the top.

[0040] The first solenoid valve 93 and the second solenoid valve 94 are electrically connected to an external centralized controller and are used to dynamically select and activate the corresponding flow channel branch according to the molding process.

[0041] In this embodiment:

[0042] During the mold forming process, the first solenoid valve 93, as the core control unit, receives instructions from the external centralized controller and dynamically selects and connects the lower mold flow channel 9 or the upper mold flow channel 4, thereby providing active temperature regulation capability for heating or cooling specific areas of the mold. At the same time, the heat diffusion insert 96 efficiently and uniformly diffuses the heat or cold transferred by the flow channel to the surface of the lower mold cavity 11 or the upper mold cavity 25 in the vertical direction, ensuring a consistent temperature within the area. Meanwhile, the thermal barrier layer 95 strongly blocks the lateral diffusion of heat to adjacent areas, forming a clear thermal insulation boundary. Thus, through the synergistic effect of the two sets of first solenoid valves 93 dynamically switching energy sources, the longitudinal uniform heat conduction of the heat diffusion insert 96, and the lateral blocking of heat transfer by the thermal barrier layer 95, a local temperature gradient that can be precisely programmed in both time and space is finally constructed inside the mold, achieving high-quality molding of the product.

[0043] This invention provides an improved conformal flow channel coating integrated molding die. Steam, room temperature water, and ice water circulate through the upper mold flow channel 4 and the lower mold flow channel 9 to rapidly form shoe soles, improving the automation level, molding speed, and product consistency of shoe sole forming. By setting up the upper mold flow channel 4 and the lower mold flow channel 9, and through the synergistic effect of two sets of first solenoid valves 93 dynamically switching energy sources, the longitudinal uniform heat conduction of the heat diffusion insert 96, and the lateral heat transfer barrier layer 95, a local temperature gradient that can be precisely programmed in both time and space is finally constructed inside the mold, achieving high-quality molding of the product.
