Description

Technical Field

[0001] This utility model relates to the field of medical device injection mold technology, specifically to a high-throughput suction head plate frame preparation mold. Background Technology

[0002] Compared to traditional culture plates, 384-well microplates offer a significantly higher number of wells, allowing for the use of high-throughput pipette tips to provide high-throughput sample volumes. Because a large number of pipette tips need to be fitted at once, the alignment between the wells in the 384-well microplate holder and the pipette tips is crucial; misalignment can lead to misalignment of the entire batch of pipette tips. During the fabrication of 384-well microplates, the numerous and relatively small pore sizes make them susceptible to deviations during demolding due to insufficient cooling, or injection molding errors due to insufficient flatness of the mold itself. Ensuring the flatness of the pores in 384-well microplates is a pressing issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-throughput suction head plate preparation mold.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A high-throughput suction head plate holder preparation mold includes a matching upper mold and a lower mold, which form an injection cavity. Each lower mold has a set of axially extending accommodating cavities. Each accommodating cavity is detachably provided with an axially extending insert. The gap between the inner wall of the accommodating cavity and the outer wall of the insert forms a plate hole cavity for injection molding. The lower mold is provided with cooling pipes, and a set of cooling rods are fixedly connected to the cooling pipes. Each set of cooling rods is arranged in a one-to-one correspondence with a set of inserts, and each insert has a cooling rod inserted to cool the plate hole cavity.

[0006] Preferably, a group of plate cavity cavities are arranged in an array, the cooling pipeline includes an input pipe and an output pipe, and a set of connecting branch pipes are arranged at intervals between the input pipe and the output pipe, each of the connecting branch pipes being directly opposite a row or column of plate cavity cavities.

[0007] Preferably, a connecting channel matching the cooling rod is provided between the interior of the insert and the connecting branch pipe, the top of the cooling rod extends into the interior of the insert from the connecting channel, and the cooling rod is coaxial with the plate cavity.

[0008] Preferably, the cooling rod is fixedly connected to the connecting branch pipe, and the bottom of the cooling rod extends into the connecting branch pipe.

[0009] Preferably, the cooling rod is made of beryllium copper.

[0010] Preferably, the bottom of the accommodating cavity has a screw hole, the bottom outer wall of the insert has a thread, and the insert is screwed to the accommodating cavity.

[0011] Preferably, the top of the insert is recessed with a hexagonal plate hole.

[0012] Preferably, the accommodating cavity includes a first cavity and a second cavity arranged from top to bottom, the inner diameter of the first cavity is larger than that of the second cavity, and a first stepped surface is formed between the two. The insert includes a first tube and a second tube arranged from top to bottom, and a second stepped surface matching the first stepped surface is formed between the first tube and the second tube. The second stepped surface abuts against the first stepped surface, and the plate hole cavity is formed between the first cavity and the first tube.

[0013] Preferably, a sealing ring is embedded on the outer wall of the second tube portion, and the sealing ring seals the gap between the second cavity portion and the second tube portion.

[0014] The beneficial effects of this utility model are mainly reflected in:

[0015] 1. Inserts are detachably set in the lower mold to cooperate with the receiving cavity to form a plate hole cavity. The inserts are used to form the inner wall of the plate hole. The replaceability of the inserts means that by ensuring the straightness of the outer wall of the insert, the straightness of the inner wall of the plate hole can be ensured, thereby ensuring the fit between the plate hole and the suction head, and avoiding the failure of suction head insertion due to offset or size mismatch.

[0016] 2. The replaceability of the inserts also makes it easy to ensure that the inner wall of the plate hole remains consistent by replacing the inserts, and the wall thickness and other requirements of the plate hole can be controlled by replacing the inserts as a whole, so as to injection mold plate holes of different specifications.

[0017] 3. A cooling rod, made of beryllium copper, is inserted into the insert and fixed to the cooling pipe. This increases the cooling rate of the insert, thereby increasing the cooling rate of the inner wall of the plate hole cavity. This allows for rapid forming of the plate hole, especially the inner wall. The cooling rod is coaxially fitted with the plate hole cavity, ensuring a uniform cooling effect on the inner wall of the plate hole. Rapid forming of the plate hole ensures that it is formed before demolding, avoiding deviations that could affect the straightness of the inner wall of the plate hole in the unformed state.

[0027] like Figures 1 to 6 As shown, this utility model discloses a high-throughput suction head plate holder manufacturing mold, including a matching upper mold (not shown in the figure) and a lower mold 1, which form an injection cavity 100. Each of the lower mold 1 is provided with a set of axially extending accommodating cavities 101. Each accommodating cavity 101 is detachably provided with an axially extending insert 102. The gap between the inner wall of the accommodating cavity 101 and the outer wall of the insert 102 forms a plate hole cavity 200 for injection plate holes. The lower mold 1 is provided with a cooling pipe 2, and a set of cooling rods 201 are fixedly connected to the cooling pipe 2. Each set of cooling rods 201 is arranged in a one-to-one correspondence with a set of inserts 102, and each insert 102 is provided with a cooling rod 201 to cool the plate hole cavity 200.

[0028] Preferably, a group of the plate cavity 200s are arranged in an array to accommodate high-throughput pipette tip arrangements. The cooling pipeline 2 includes an input pipe 202 and an output pipe 203. A set of connecting branch pipes 204 are spaced apart between the input pipe 202 and the output pipe 203. Each connecting branch pipe 204 is directly opposite a row or column of the plate cavity 200 to improve the fitting accuracy between the cooling pipeline 2 and the plate cavity 200, reduce unnecessary cooling range, and improve the cooling effect under the same cooling water volume.

[0029] A connecting channel 104, matching the cooling rod 201, is provided between the insert 102 and the connecting branch pipe 204. This allows the top of the cooling rod 201 to extend into the insert 102 through the connecting channel 104. The cooling rod 201 is coaxial with the plate hole cavity 200. The cooling rod 201, which is fixed to the cooling pipe 2, extends into the insert 102, thereby increasing the cooling rate of the insert 102 and thus increasing the cooling rate of the inner wall of the plate hole cavity 200. This facilitates rapid forming of the plate hole, especially the inner wall, ensuring that the suction head can be inserted into the plate hole. Furthermore, the coaxial fit between the cooling rod 201 and the plate hole cavity 200 ensures a uniform cooling effect on the inner wall of the plate hole. Rapid forming of the plate hole ensures that it is completed before demolding, preventing deviations in the unformed state from affecting the straightness of the inner wall of the plate hole.

[0030] Furthermore, the cooling rod 201 is fixedly connected to the connecting branch pipe 204, and the bottom of the cooling rod 201 extends into the connecting branch pipe 204 to further enhance the cooling effect of the cooling water in the connecting branch pipe 204 on the cooling rod 201.

[0031] The cooling rod 201 is made of beryllium copper to enhance its cooling effect by utilizing the good thermal conductivity of beryllium copper.

[0032] The bottom of the accommodating cavity 101 has a screw hole, and the bottom outer wall of the insert 102 has threads. The insert 102 is screwed to the accommodating cavity 101. Furthermore, to facilitate quick assembly and disassembly between the insert 102 and the accommodating cavity 101, the top of the insert 102 is recessed with a hexagonal plate hole 103 to facilitate the connection of a hexagonal wrench for rotation.

[0033] The insert 102 is mainly used to form the inner wall of the plate hole. The insert 102 is detachably installed in the lower mold 1 to cooperate with the receiving cavity 101 to form the plate hole cavity 200. This makes the insert 102 replaceable. The replaceability of the insert 102 ensures the straightness of the inner wall of the plate hole by maintaining the straightness of the outer wall of the insert 102, thereby ensuring the fit between the plate hole and the suction head and avoiding suction head insertion failure due to misalignment or size mismatch. Furthermore, the replaceability of the insert 102 also allows for maintaining a consistent straightness of the inner wall of the plate hole by replacing the insert 102. Moreover, the wall thickness and other requirements of the plate hole can be controlled by replacing the entire insert 102 to injection mold plate holes of different specifications, thereby improving the applicability of the mold.

[0034] Furthermore, the accommodating cavity 101 includes a first cavity 1011 and a second cavity 1012 arranged from top to bottom. The inner diameter of the first cavity 1011 is larger than that of the second cavity 1012, and a first stepped surface 1013 is formed between the two. The insert 102 includes a first tube 1021 and a second tube 1022 arranged from top to bottom. A second stepped surface 1023 matching the first stepped surface 1013 is formed between the first tube 1021 and the second tube 1022. The second stepped surface 1023 abuts against the first stepped surface 1013. The plate hole cavity 200 is formed between the first cavity 1011 and the first tube 1021. The second step surface 1023 abuts against the first step surface 1013, thereby limiting the extreme position of the screw connection of the insert 102 by the first step surface 1013, and thus limiting the position of the first tube portion 1021 of the insert 102, so as to ensure that the same plate hole cavity 200 is formed between each first cavity portion 1011 and each first tube portion 1021, thereby ensuring that consistent plate holes can be injection molded.

[0035] To ensure the airtightness of the plate cavity 200, a sealing ring 105 is embedded on the outer wall of the second tube 1022. The sealing ring 105 seals the gap between the second cavity 1012 and the second tube 1022 to prevent moisture and other substances from entering the plate cavity 200.

[0036] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0037] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
