Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to an injection mold for a chemiluminescence analyzer connecting tube. Background Technology

[0002] Chemiluminescence analyzer connecting tubes are plastic products, typically manufactured through injection molding. First, plastic granules are heated and melted. Then, the molten liquid plastic is injected into an injection mold using an injection molding machine. After the liquid plastic cools and solidifies, the connecting tube is obtained. Chemiluminescence analyzer connecting tube injection molds often use natural cooling or simple water cooling. These methods are slow and inefficient, resulting in long production cycles. Furthermore, water cooling is usually only applied to the outside of the mold cavity, leading to uneven heating and cooling inside and outside the connecting tube, causing product deformation, increasing the scrap rate, and making the mold inside the connecting tube prone to deformation and damage due to prolonged high temperatures. Utility Model Content

[0003] The purpose of this invention is to provide an injection mold for a chemiluminescence analyzer connecting tube, so as to solve the problems of slow cooling speed and uneven cooling in existing injection molds for chemiluminescence analyzer connecting tubes.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A chemiluminescence analyzer connecting tube injection mold includes a fixed base and a movable plate slidably disposed on one side of the fixed base. A plurality of guide rods are fixedly connected to one side of the fixed base, and a fixed mold and a movable mold are disposed between the plurality of guide rods. A connecting column is fixedly installed on one side of the movable plate. One side of the movable mold is fixedly connected to the connecting column, and one side of the fixed mold is fixedly connected to the fixed base. When the fixed mold and the movable mold are closed, an injection space is formed in the middle. A second cooling channel and a first cooling channel are respectively disposed in the fixed mold and the movable mold, and the second cooling channel and the first cooling channel are respectively located on both sides of the injection space.

[0006] Preferably, both sides of the fixed mold and the moving mold are fixed with water inlet pipes and water outlet pipes, and the two sets of water inlet pipes and water outlet pipes are respectively connected to the two ends of the first cooling channel and the second cooling channel.

[0007] Preferably, both the first cooling channel and the second cooling channel have a double-helix structure.

[0008] Preferably, the moving mold has an exhaust hole on one side, and one end of the exhaust hole is connected to the injection space.

[0009] Preferably, a second top plate is slidably connected inside the fixed base. A plurality of second springs are fixedly installed between one side of the second top plate and the fixed base, and a plurality of second push rods are fixedly installed on the other side of the second top plate. The ends of the plurality of second push rods all slide through one end of the fixed mold.

[0010] Preferably, a first top plate is slidably sleeved on the outer side of the connecting column, a plurality of first springs are fixedly connected between one side of the first top plate and the moving plate, and a plurality of first push rods are fixedly installed on the other side of the first top plate, with the ends of the plurality of first push rods sliding through one end of the moving mold.

[0011] Preferably, a plurality of sliding rods are fixedly installed on one side of the second top plate, and the plurality of sliding rods are slidably connected to a plurality of guide rods, and the ends of the plurality of sliding rods extend to the outside of the guide rods. A plurality of recesses are provided on one side of the first top plate to abut against the plurality of sliding rods.

[0012] Preferably, the sum of the lengths of the sink, the first ejector rod, the injection space, and the second ejector rod is equal to the length of the slide rod.

[0013] Preferably, one end of the fixed mold is provided with an injection port, and an injection hole is connected between the injection port and the injection space.

[0014] Preferably, a through hole is provided in the middle of the second top plate, and the through hole is located on one side of the injection port.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) This utility model is provided with a first cooling channel and a second cooling channel. Water cooling is performed through the second cooling channel in the fixed mold and the first cooling channel in the moving mold. The first cooling channel and the second cooling channel are located on both sides of the injection space, which can cool the inner and outer sides of the finished connecting pipe in the injection space at the same time. The cooling speed is relatively fast, and the temperature of the mold can also be reduced, avoiding the mold from deforming at high temperature for a long time. This is conducive to continuous production and improves production efficiency.

[0017] (2) As mentioned above, both the first cooling channel and the second cooling channel are double-helix structures, which can uniformly cool the inner and outer sides of the connecting pipe, avoid uneven cooling of the connecting pipe and deformation, and reduce the scrap rate.

[0018] (3) This utility model is provided with a first top plate, a first ejector rod, a second top plate, and a second ejector rod. After the connecting tube is cooled and formed in the injection mold, the fixed mold and the moving mold are separated. If the finished connecting tube is on the outside of the fixed mold, the second spring pushes the second top plate to push the finished connecting tube with the second ejector rod, so that one end of the finished connecting tube slides out of the fixed mold end. If the finished connecting tube is on the inside of the moving mold, the first spring pushes the first top plate to push the first ejector rod to push the finished connecting tube, so that one end of the finished connecting tube extends out of the moving mold. Thus, after the fixed mold and the moving mold are separated, the finished connecting tube can be easily removed and unloaded from either side, improving production efficiency.

[0019] (4) The present invention is provided with a sliding rod. When the groove on the first top plate pushes the sliding rod to make the second top plate press against the fixed seat, the sum of the lengths of the groove, the first top rod, the injection space and the second top rod is equal to the length of the sliding rod. This makes the first top rod and the second top rod located on both sides of the injection space. This prevents the first top rod and the second top rod from extending into the injection space during the injection molding process and affecting the molding of the connecting pipe. In this way, the sliding rod restricts the position of the first top plate and the second top plate during the injection molding process. There is no need to set up a separate driving device, which reduces the equipment cost. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0028] A chemiluminescence analyzer connecting tube injection mold includes a fixed base 1 and a movable plate 7 slidably disposed on one side of the fixed base 1. A plurality of guide rods 5 are fixedly connected to one side of the fixed base 1. A fixed mold 2 and a movable mold 3 are disposed between the plurality of guide rods 5. A connecting column 8 is fixedly installed on one side of the movable plate 7. One side of the movable mold 3 is fixedly connected to the connecting column 8. One side of the fixed mold 2 is fixedly connected to the fixed base 1. When the fixed mold 2 and the movable mold 3 are closed, an injection space is formed in the middle. A second cooling channel 12 and a first cooling channel 11 are respectively provided in the fixed mold 2 and the movable mold 3. The second cooling channel 12 and the first cooling channel 11 are respectively located on both sides of the injection space.

[0029] Both the fixed mold 2 and the moving mold 3 have water inlet pipes 21 and water outlet pipes 10 fixed through them on both sides. The two sets of water inlet pipes 21 and water outlet pipes 10 are respectively connected to the two ends of the first cooling channel 11 and the second cooling channel 12. The first cooling channel 11 and the second cooling channel 12 are both double spiral structures.

[0030] The moving mold 3 has an exhaust hole 4 on one side, and one end of the exhaust hole 4 is connected to the injection space; the fixed mold 2 has an injection port 17 on one end, and an injection hole 22 is connected between the injection port 17 and the injection space.

[0031] Based on the above-disclosed structure, when performing the connecting pipe production operation:

[0032] First, the moving plate 7 is moved towards the fixed base 1 by an external hydraulic push rod, so that the connecting column 8 drives the moving mold 3 to approach the fixed mold 2, so that the fixed mold 2 and the moving mold 3 are closed, forming an injection space between the fixed mold 2 and the moving mold 3. Then, the molten liquid plastic is injected into the injection port 17 by an external injection molding machine. The liquid plastic flows into the injection space through the injection hole 22 and gradually fills the injection space. At the same time, the air in the injection space is discharged through the exhaust hole 4 to prevent air bubbles from entering the finished connecting tube. Then, cold water is injected into the water inlet pipe 10 on the outside of the fixed mold 2 and the moving mold 3 respectively. The cold water flows through the second cooling channel 12 and the first cooling channel 11 respectively. The first cooling channel 11 and the second cooling channel 12 are both double spiral structures, so that the cold water flows evenly on both sides of the injection space, thereby accelerating the temperature drop of the finished connecting tube, improving production efficiency, and ensuring that the temperature on both sides of the finished connecting tube is uniform, avoiding deformation caused by uneven cooling of the connecting tube.

[0033] After the finished connecting pipe has cooled and solidified, the external hydraulic push rod pulls the moving plate 7 to move away from the fixed base 1. The moving plate 7 drives the moving mold 3 to separate from the fixed mold 2 through the connecting column 8. Then the finished connecting pipe that has cooled and solidified can be taken out and unloaded, thus completing the production of the connecting pipe.

[0034] In addition, to facilitate the cutting of the finished connecting pipe, the following structure is preferred:

[0035] A second top plate 15 is slidably connected inside the fixed base 1. Multiple second springs 20 are fixedly installed between one side of the second top plate 15 and the fixed base 2. Multiple second ejector rods 13 are fixedly installed on the other side of the second top plate 15. The ends of the multiple second ejector rods 13 all slide through one end of the fixed mold 2.

[0036] A first top plate 6 is slidably sleeved on the outside of the connecting column 8. A plurality of first springs 18 are fixedly connected between one side of the first top plate 6 and the moving plate 7. A plurality of first push rods 9 are fixedly installed on the other side of the first top plate 6. The ends of the plurality of first push rods 9 slide through one end of the moving mold 3.

[0037] A plurality of sliding rods 14 are fixedly installed on one side of the second top plate 15. The plurality of sliding rods 14 are slidably connected to a plurality of guide rods 5, and the ends of the plurality of sliding rods 14 extend to the outside of the guide rods 5. A plurality of recesses 19 are provided on one side of the first top plate 6 to abut against the plurality of sliding rods 14.

[0038] The sum of the lengths of the sink 19, the first ejector rod 9, the injection space, and the second ejector rod 13 is equal to the length of the slide rod 14.

[0039] As can be seen from the above, when the moving plate 7 drives the connecting column 8 and the moving mold 3 to approach the fixed mold 2, the end of the sliding rod 14 sliding inside the guide rod 5 first contacts the groove 19 on one side of the first top plate 6. The first spring 18 and the second spring 20 between the fixed seat 1 and the moving plate 7 keep the first top plate 6 and the second top plate 15 fixed at both ends of the sliding rod 14. As the moving plate 7 continues to move, the first spring 18 and the second spring 20 are continuously compressed until one side of the second top plate 15 contacts the fixed seat 1. At this time, one side of the first top plate 6 contacts the moving plate 7. Since the sum of the lengths of the groove 19, the first ejector rod 9, the injection space and the second ejector rod 13 is equal to the length of the sliding rod 14, the ends of the first ejector rod 9 and the second ejector rod 13 are located on both sides of the injection space. Thus, the first ejector rod 9 and the second ejector rod 13 are prevented from extending into the injection space during the injection molding process by the restriction of the sliding rod 14.

[0040] Then, after the connecting tube is cooled and formed in the injection space, when the moving plate 7 moves the connecting column 8 and the moving mold 3 away from the fixed mold 2, the spring force of the first spring 18 pushes the first top plate 6 closer to the moving mold 3, and the spring force of the second spring 21 pushes the second top plate 15 closer to the fixed mold 2. Thus, if the connecting tube is inside the moving mold 3 when the fixed mold and the moving mold are separated, the first top plate 6 drives the first ejector rod 9 to push the connecting tube to move, so that one end of the connecting tube slides out of the outside of the moving mold 3. If the connecting tube is outside the fixed mold 2 when the fixed mold and the moving mold are separated, the second top plate 15 drives the second ejector rod 13 to push the connecting tube to move, so that one end of the connecting tube slides out of the end of the fixed mold 2. Thus, the connecting tube can be easily removed from either side through the extended end of the connecting tube, improving production efficiency.

[0041] In addition, a through hole 16 is provided in the middle of the second top plate 15, which is located on one side of the injection port 17. Based on this, an external injection molding machine can inject liquid plastic through the through hole 16 in the middle of the second top plate 15 into the injection port 17, so that the second top plate 15 will not obstruct the injection molding process.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
