Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, and in particular to a die-cutting mold and a die-cutting device. Background Technology

[0002] In the production of waterproof and breathable membranes, existing die-cutting molds in the industry often result in varying degrees of adhesive residue on the adhesive layer, leading to residual adhesive in the inner pore areas. This residue can cause embossing defects at the pore edges in subsequent processes. This defect not only directly affects the product's appearance but, more importantly, severely degrades the acoustic performance of the breathable membrane, preventing the product's core functions (such as sound transmission and frequency response) from meeting the requirements of high-end customers. This becomes a bottleneck restricting product quality upgrades and customer satisfaction. To address this residual adhesive accumulation problem, production lines must frequently interrupt production for mold cleaning. This unplanned downtime significantly reduces equipment uptime, increases manual intervention costs, extends product delivery cycles, and severely restricts production efficiency and the overall smoothness and economy of the manufacturing process. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a die-cutting mold and a die-cutting device, which can reduce the occurrence of residual adhesive, improve product molding quality, and simultaneously reduce production costs and increase production efficiency.

This reduces the likelihood of adhesive sticking during the punching process, thereby reducing residual adhesive and improving product molding quality. Furthermore, the lubrication channel on the stripper plate, connected to the flow guide structure, allows for timely replenishment of lubricating medium, ensuring the punch remains lubricated without excessive manual intervention. This reduces production costs and increases production efficiency.

[0006] In one embodiment of this implementation, the stripper plate has an installation groove on the side facing the moving template, the flow guiding structure is installed in the installation groove, and the lubrication channel is connected to the installation groove.

[0024] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a die-cutting mold 100 according to one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the moving template 21 in the die-cutting mold 100 from a bottom view. Figure 3 yes Figure 1 A schematic diagram of the stripper plate 22 in a die-cutting mold 100 from a top view. This utility model provides a die-cutting mold 100, which includes a fixed mold mechanism 10 and a moving mold mechanism 20. The fixed mold mechanism 10 includes a fixed template 11 for carrying the die material. The moving mold mechanism 20 includes a moving template 21 and a stripper plate 22. The moving template 21 is provided with a punch 211. The stripper plate 22 is relatively movably connected to the moving template 21 and located between the moving template 21 and the fixed template 11. The stripper plate 22 is provided with a guide structure 221 for the punch 211 to pass through. The stripper plate 22 has a lubrication channel 2201, which communicates with the guide structure 221 and is used to allow a lubricating medium to pass through and wet the guide structure 221.

[0025] Specifically, to enable the installation of the fixed template 11, the fixed template mechanism 10 includes a first pad 12 and a fixed template base 13. The fixed template 11 is installed onto the fixed template base 13 via the first pad 12, and the fixed template base 13 is used to fix it to the base platform. To enable relative movement between the movable template 21 and the fixed template 11, the movable template mechanism 20 includes a second pad 23 and a movable template base 24. The movable template 21 is installed onto the movable template base 24 via the second pad 23, and the movable template base 24 is used to connect to a power mechanism so that, under the drive of the power mechanism, the movable template 21 can move relative to the fixed template 11.

[0026] Understandably, the stripper plate 22 is used to strip the film material after the moving die plate 21 and the fixed die plate 11 cooperate to perform stamping, so that the film material stays on the fixed die plate 11. Therefore, during the stamping process, there is relative movement between the punch 211 and the stripper plate 22, and during the relative movement, the guide structure 221 can provide sufficient lubrication for the punch 211.

[0027] In this embodiment, the membrane material is constructed as a waterproof and breathable membrane, which requires punches 211 to form vent holes. Accordingly, the number of punches 211 is the same as the number of vent holes.

[0028] By setting a flow guiding structure 221 on the stripper plate 22, the punch 211 on the moving template 21 passes through the flow guiding structure 221, so that the lubricating medium on the flow guiding structure 221 can lubricate the punch 211. During the punching process of the film material, the punch 211 is less likely to stick, thereby reducing the occurrence of residual glue and improving the product molding quality. At the same time, a lubrication channel 2201 connected to the flow guiding structure 221 is opened on the stripper plate 22 to replenish the lubricating medium to the flow guiding structure 221 in a timely manner, ensuring that the punch 211 can remain lubricated without excessive manual intervention, thereby reducing production costs and improving production efficiency.

[0029] In one embodiment of this implementation, please refer to Figure 3 In order to facilitate the installation of the flow guide structure 221 and the replenishment of lubricating medium to the flow guide structure 221, the stripper plate 22 is provided with an installation groove 2202 on the side facing the moving template 21, the flow guide structure 221 is installed in the installation groove 2202, and the lubrication channel 2201 is connected to the installation groove 2202.

[0030] Specifically, there are two mounting slots 2202 and two flow guiding structures 221, with each flow guiding structure 221 installed in one of the mounting slots 2202. There are also two lubrication channels 2201, which are connected to their respective mounting slots 2202, thus allowing the stamping of two breathable membranes to be completed simultaneously.

[0031] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 In order to facilitate the lubrication of the punch 211 by the flow guiding structure 221, the bottom wall of the mounting groove 2202 is provided with a first through hole 22021, and the flow guiding structure 221 is provided with a second through hole 2211. One end of the punch 211 is fixed to the moving template 21, and the other end passes through the second through hole 2211 and the first through hole 22021 in sequence.

[0032] Specifically, there are multiple first through holes 22021 and multiple second through holes 2211, and they correspond one-to-one. There are multiple punches 211, and the multiple punches 211 are respectively inserted into the corresponding first through holes 22021 and second through holes 2211.

[0033] In one embodiment of this implementation, please refer to Figure 3 The flow guiding structure 221 is constructed of foam. It is understood that foam has excellent liquid absorption capacity and can store a large amount of lubricating medium, thereby reducing the frequency of lubricating medium replenishment and improving efficiency.

[0034] In other embodiments, the flow guiding structure 221 may also be constructed as cardboard.

[0035] In one embodiment of this implementation, please refer to Figure 3 The lubricating medium is configured as a lubricating oil mist. This configuration avoids excessive lubricating medium in the flow guide structure 221, which could lead to leakage. At the same time, the lubricating oil mist can better achieve timed and controlled supply.

[0036] In one embodiment of this implementation, please refer to Figure 1 and Figure 3 In order to facilitate the stripping plate 22 to strip and reset, the moving template 21 and the stripping plate 22 are slidably fitted together, and an elastic element is provided between them.

[0037] Specifically, the stripper plate 22 and the moving template 21 achieve a sliding fit through guide posts and guide sleeves.

[0038] In one embodiment of this implementation, please refer to Figure 5 , Figure 5 yes Figure 1 A schematic diagram of the fixed template 11 in the die-cutting mold 100 from a top view. The fixed template 11 has punch holes 1101 opposite to the punch 211. This arrangement allows waste material generated when the punch 211 forms the vent holes to leave the fixed template 11.

[0039] Specifically, there are multiple punches 211 and punch holes 1101, and they are set in a one-to-one correspondence. In this embodiment, there are two sets of punches 211 and punch holes 1101, with 12 punches 211 and punch holes 1101 in each set, arranged in 4 rows and 3 columns.

[0040] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 , Figure 4 yes Figure 1is a schematic structural diagram of the stripper plate 22 in the die-cutting processing mold 100 in the front view direction. The lubrication channel 2201 is opened on the peripheral side of the stripper plate 22. Such arrangement facilitates the communication between the lubrication channel 2201 and the liquid supply mechanism.

[0041] In an example of this embodiment, please refer to Figure 4 , the fixed mold plate 11 is provided with a cooling channel 1102 for the circulation of a cooling medium. Such arrangement allows the cooling medium to timely cool the fixed mold plate 11, ensuring the fixed mold plate 11 does not overheat, extending the service life of the fixed mold plate 11, thereby reducing production costs, lowering mold change frequency, and improving production efficiency.

[0042] Specifically, to enable turbulent heat exchange of the cooling medium, the cross section of the cooling channel 1102 is configured as a trapezoid.

[0043] Specifically, the cooling channel 1102 is in a "concave" shape, so that it can pass through the stamping areas of two film materials to dissipate heat in time. In this embodiment, the flow controller maintains the flow rate of the cooling medium at ≥ 3m / s, ensuring the temperature gradient of the mold surface ≤ 8°C (the punching area is cooled preferentially, and the temperature gradient of the mold surface refers to the temperature difference between the fixed mold plate 11 and the surrounding environment), and finally the working temperature is stabilized below 25°C (40°C lower than the conventional one).

[0044] Please refer to Figures 1 to 3 , an embodiment of the present utility model provides a die-cutting processing device, which includes a liquid supply mechanism (not shown) and the die-cutting processing mold 100 of the embodiment of the present utility model. The liquid supply mechanism is connected to the lubrication channel 2201 of the die-cutting processing mold 100 and is configured to supply the lubricating medium to the lubrication channel 2201. By incorporating the die-cutting processing mold 100 of the embodiment of the present utility model into the die-cutting processing device, the die-cutting processing mold 100 can improve the product forming quality, while reducing production costs and improving production efficiency.

[0045] Specifically, to ensure the lubrication consistency of the punch 211 during the processing, the liquid supply mechanism periodically injects a quantitative amount of lubricating oil mist into the lubrication channel.

[0046] The embodiments of the present utility model are described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those of ordinary skill in the technical field, various modifications can be made without departing from the spirit of the present utility model. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
