Description

Technical Field

[0001] The utility model belongs to the technical field of forming molds for nucleic acid sampling tubes, and in particular relates to a forming mold for nucleic acid sampling tubes. Background Art

[0002] The disposable nucleic acid virus sampling tube is a detection tool used in nucleic acid testing. It can collect human oral cells and oral microorganisms, as well as surface bacteria, surface microorganisms and DNA sampling. It can also be used for virus sampling and transportation, and plays a relatively important role.

[0003] Some existing forming molds are not convenient for collecting nucleic acid sampling tubes after they are made. Some nucleic acid sampling tubes may get stuck in the lower mold and are difficult to remove. In addition, manual operation is required for demolding, which is inconvenient. In view of this, we propose a forming mold for nucleic acid sampling tubes. Utility Model Content

[0004] The purpose of the utility model is to provide a forming mold for a nucleic acid sampling tube to solve the problems raised in the above-mentioned background technology.

[0005] In view of this, the utility model provides a forming mold for a nucleic acid sampling tube, comprising:

[0006] A U-shaped frame, a rotating plate is rotatably installed in the U-shaped frame, a lower mold is fixedly installed on the top of the rotating plate, an upper mold is arranged on the top of the lower mold, a connecting plate is fixedly installed on the top of the upper mold, an electric push rod is symmetrically fixedly installed on the top of the U-shaped frame, and the output end of the electric push rod is fixed to the bottom of the connecting plate, a first motor is fixedly installed on one side of the U-shaped frame, and the output shaft of the first motor passes through one side of the U-shaped frame and is coaxially connected to the rotating plate;

[0007] A protective shell, the protective shell is fixedly installed at the bottom of the rotating plate, a sliding rod is slidably installed in the protective shell, the top end of the sliding rod passes through the rotating plate and contacts the bottom of the lower mold, and fixed plates are fixedly installed on the left and right sides of the sliding rod, and a tension spring fixed to the bottom of the rotating plate is fixedly installed on the top of the fixed plate;

[0008] The driving assembly is located in the protective shell and is used to drive the sliding rod to move upward.

[0009] In this technical solution, after the injection molding is completed, the staff first starts the two electric push rods so that the output shafts of the two electric push rods drive the connecting plate to move upward, and then the connecting plate will drive the upper mold to move upward until the upper mold is separated from the lower mold, and a certain distance is created between the upper mold and the lower mold to ensure that the upper mold will not hinder the rotation of the lower mold when the rotating plate rotates. Subsequently, the staff starts the first motor so that the output shaft of the first motor drives the rotating plate to rotate, and then the rotating plate will drive the lower mold and the protective shell to rotate until the rotating plate rotates 180°. At this time, the protective shell will be located above the lower mold, and under the action of the baffle, it is ensured that the nucleic acid sampling tube in the lower mold will not fall to the outside. Subsequently, some nucleic acid sampling The sample tube will fall into the collection box under the action of gravity. When some nucleic acid sampling tubes are stuck in the lower mold and cannot fall automatically, the driving assembly is set to drive the sliding rod to move upward, and the sliding rod will drive the two fixed plates to move upward. At this time, the two tension springs will generate tension and stretch. Then, when the half gear rotates until it no longer contacts the rack, under the action of gravity and the tension of the two tension springs, the two tension springs will respectively drive the two fixed plates to move downward. Then, the two fixed plates will drive the sliding rod to move downward until the sliding rod hits the lower mold. Under the action of the continuous rotation of the half gear, the sliding rod will repeatedly hit the lower mold, so that the nucleic acid sampling tube in the lower mold can fall into the collection box.

[0010] In the above technical solution, further, the driving component includes:

[0011] A rack is fixedly mounted on the front side of the sliding rod, a half gear is rotatably mounted in the protective shell and on one side of the rack, the half gear is meshed with the rack, a second motor is fixedly mounted on one side of the protective shell, and the output shaft of the second motor passes through one side of the protective shell and is coaxially connected to the half gear.

[0012] In this technical solution, the staff starts the second motor so that the output shaft of the second motor drives the half gear to rotate. When the half gear rotates, when the teeth on the half gear contact the rack, under the action of meshing, the half gear continues to rotate and will drive the rack to move upward, ensuring that the rack can be driven to move upward.

[0013] In the above technical solution, further, the output shaft of the second motor is rotationally connected to one side of the protective shell.

[0014] In this technical solution, it is ensured that the second motor can operate normally.

[0015] In the above technical solution, further, the output shaft of the first motor is rotationally connected to one side of the U-shaped frame.

[0016] In this technical solution, it is ensured that the first motor can operate normally.

[0017] In the above technical solution, further, a baffle is fixedly installed on the rear side of the U-shaped frame, and a collection box is plugged and installed in the U-shaped frame and below the protective shell.

[0018] In the present technical solution, the baffle can prevent the nucleic acid sampling tube from falling to the outside; and the collection box can collect the nucleic acid sampling tube in the lower mold.

[0019] In the above technical solution, further, the sliding rod is slidably connected to the rotating plate, and the output end of the electric push rod is tightly welded to the connecting plate.

[0020] In this technical solution, it is ensured that the sliding rod can slide on the rotating plate; and it is ensured that the structure between the output shaft of the electric push rod and the connecting plate is stable.

[0021] The beneficial effects of the utility model are:

[0022] The nucleic acid sampling tube molding mold, after injection molding is completed, the staff first starts the two electric push rods, so that the output shafts of the two electric push rods drive the connecting plate to move upward, and then the connecting plate will drive the upper mold to move upward until the upper mold is separated from the lower mold, and the first motor will drive the rotating plate to rotate, and then the rotating plate will drive the lower mold and the protective shell to rotate until the rotating plate rotates 180 degrees, and then some nucleic acid sampling tubes will fall into the collection box under the action of gravity. When some nucleic acid sampling tubes are stuck in the lower mold and cannot fall automatically, the driving assembly is set to drive the sliding rod and the two fixed plates to move upward. When the sliding rod is displaced upward, the two tension springs will generate tension and stretch. Subsequently, when the driving assembly no longer drives the sliding rod to displace upward, under the action of the tension of the two tension springs, the two tension springs will respectively drive the two fixed plates to displace downward, and the two fixed plates will drive the sliding rod to displace downward and hit the lower mold. Under the repeated driving of the driving assembly, the sliding rod will drive the rubber pad to repeatedly hit the lower mold, so that the nucleic acid sampling tube in the lower mold can fall into the collection box. The overall device does not require manual operation when in use, and the nucleic acid sampling tube stuck in the lower mold can be taken out under the action of impact, without the need for personnel to take it out, which is more convenient and saves manpower.
