Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing accessories, and in particular to a microporous mold. Background Technology

[0002] Microporous molds are mainly used in the manufacturing of precision medical devices to process components with specific micron-level pore structures, which play a key role in medical applications.

[0003] In addition, in the application of microporous molds for precision medical devices, heat dissipation issues directly affect mold life, processing accuracy, and product consistency, especially in high-speed processing or high-density microporous structures. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a micro-hole mold that solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a micro-hole mold, comprising a punch base and a punch that are inserted into each other, the punch base including a slot at the top, the punch being inserted into the slot, a protrusion in the middle of the slot, the insertion end of the punch abutting against the upper surface of the protrusion; the punch base having a through channel, one end of the channel extending out of the slot and located next to the protrusion, and a recessed portion communicating with the slot on one side of the top of the punch base.

[0006] Furthermore, the recessed portion is located above the channel.

[0007] Furthermore, the punch seat is provided with a first movable cavity that extends through the upper and lower ends, and a ejector pin is inserted into the first movable cavity. The punch head is provided with a second movable cavity that extends through the upper and lower ends, and a core is inserted into the second movable cavity. The lower end of the core abuts against the upper end of the ejector pin.

[0008] Furthermore, the contact ends of the ejector pin and the core are provided with a connecting port, and the side walls of both the ejector pin and the core are provided with a through port that communicates with the connecting port.

[0009] Furthermore, the ejector pin is adapted to the first movable cavity, and the upper end of the ejector pin is arc-shaped, while the lower end is connected to a connecting part, which is larger than the first movable cavity.

[0010] Furthermore, the upper end of the core is provided with an extension section, and there is a gap between the inner wall of the extension section and the inner wall of the second moving cavity.

[0011] Furthermore, an expansion port communicating with the second moving cavity is provided on one side of the lower end of the punch so that the upper opening of the core is exposed.

[0012] Furthermore, the punch is adapted to the slot, and the lower end of the punch is provided with an expansion groove smaller than the protrusion.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by the contact between the protrusion set in the slot and the lower end of the punch, a heat dissipation gap is formed between the punch and the bottom end of the slot, so that airflow can flow through the channel on the punch seat, the concave part and the punch, thereby dissipating heat from the punch seat and the punch, and increasing the use effect of this micro-hole mold.

[0024] Please refer to Figure 1-4As shown, this invention illustrates the specific structure of a preferred first embodiment of a micro-perforated mold, comprising a punch base 10 and a punch 20 that are inserted into each other. The punch base 10 includes a slot 11 with an opening at its top, into which the punch 20 is inserted. A protrusion 12 is provided in the middle of the slot 11, and the insertion end of the punch 20 abuts against the upper surface of the protrusion 12. The punch base 10 has a through channel 13, one end of which protrudes from the slot 11 and is located next to the protrusion 12. A recess 14 communicating with the slot 11 is provided on one side of the top of the punch base 10. In this micro-perforated mold, the protrusion 12 in the slot 11 abuts against the lower end of the punch 20, creating a heat dissipation gap between the punch 20 and the bottom of the slot 11. This allows airflow to pass through the channel 13, the recess 14, and the punch 20 on the punch base 10, thereby dissipating heat from the punch base 10 and the punch 20 and improving the performance of the micro-perforated mold.

[0025] For example, the recess 14 is located above the channel 13;

[0026] In one example, because the recess 14 is located above the channel 13, when gas enters or exits the channel 13, some of it is discharged through the recess 14, thereby increasing the gas flow rate.

[0027] In another example, because the recess 14 is located above the channel 13, when gas enters the slot 11 through the recess 14, it is easier to enter the channel 13 and the punch 20, thereby enhancing the heat dissipation effect.

[0028] For example, the punch holder 10 has a first moving cavity 15 extending from top to bottom, and a ejector pin 16 is inserted into the first moving cavity 15. The punch 20 has a second moving cavity 201 extending from top to bottom, and a core 21 is inserted into the second moving cavity 201. The lower end of the core 21 abuts against the upper end of the ejector pin 16. The core 21 can move up and down according to usage requirements under the push of the ejector pin 16.

[0029] For example, the contact ends of the ejector pin 16 and the core 21 are provided with a connecting port 31, and the side walls of the ejector pin 16 and the core 21 are provided with a through port 32 communicating with the connecting port 31. The opening of the connecting port 31 allows the operator to add connectors to the ejector pin 16 and the core 21 to connect the ejector pin 16 and the core 21 together.

[0030] For example, the ejector pin 16 is adapted to the first moving cavity 15, and the upper end of the ejector pin 16 is arc-shaped, and the lower end is connected to a connecting part 161, which is larger than the first moving cavity 15. The ejector pin 16 is larger than the core 21. The opening of the connecting part 161 ensures that the ejector pin 16 will not move excessively when it moves upward in the first moving cavity 15.

[0031] The upper end of the core 21 is provided with an extension 22, and there is a gap of 40 between the inner wall of the extension 22 and the inner wall of the second moving cavity 201.

[0032] An expansion port 23 communicating with the second moving cavity 201 is provided on one side of the lower end of the punch 20, so that the through port 32 on the core 21 is exposed. The expansion port 23 is provided to facilitate the operator to operate the connection between the core 21 and the ejector pin 16 after the punch seat 10 and the punch 20 are inserted.

[0033] The punch 20 is adapted to the slot 11, and the lower end of the punch 20 is provided with an expansion slot 24 smaller than the protrusion 12. The expansion slot 24 provides space for the operator to operate at the connection between the core 21 and the ejector pin 16.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
