Description

Technical Field

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

[0002] A chemiluminescence analyzer, also known as a chemiluminescence immunoassay analyzer, is a device that performs immunoassay by detecting patient serum. During sampling, to avoid contaminating subsequent samples and affecting the accuracy of the test, the sampling needle needs to be cleaned by the cleaning components of the chemiluminescence analyzer after sampling. The cleaning nozzle plays a crucial role in this process. Currently, cleaning nozzles are mostly manufactured using injection molding. While existing injection molds can produce cleaning nozzles, they have certain drawbacks. During injection molding, the mold needs to be connected to the drive structure. The current connection method uses bolts for fixing. When personnel change the mold, many fixing structures need to be disassembled, making mold replacement difficult and inefficient. Furthermore, when the mold is demolded, the cleaning nozzle tends to fall in all directions, making collection inconvenient and inefficient. Utility Model Content

[0027] 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.

[0028] Please see Figures 1-8 As shown, this utility model provides the following technical solution:

[0029] A chemiluminescence analyzer cleaning nozzle injection mold includes a support 1 and a mold 3. The top of the support 1 is symmetrically recessed to form two top grooves 14, and the top of the support 1 is also symmetrically recessed to form two positioning grooves 19. The positioning grooves 19 are located on one side of the top grooves 14. The interior of each of the two top grooves 14 is rotatably connected to a lead screw 16 along an axis parallel to the horizontal plane. Each of the two lead screws 16 is fitted with a movable moving block 17, and the top of the moving block 17 is recessed to form a slot 18.

[0030] The mold part 3 includes a fixed mold part and a moving mold part. A molding cavity for injection molding production of cleaning nozzles is formed between the fixed mold part and the moving mold part. Insert brackets 36 are fixedly connected to both sides of the moving mold part symmetrically. Insert brackets 36 match slots 18. Positioning rods 33 are fixedly connected to both sides of the fixed mold part symmetrically. Positioning rods 33 match positioning grooves 19.

[0031] With the above technical solution, before the cleaning nozzle needs to be produced, the moving mold part is placed between the two moving blocks 17, so that the two inserts 36 on the moving mold part are respectively inserted into the slots 18 on the two moving blocks 17, thereby installing the moving mold part between the two moving blocks 17. Then, the fixed mold part is placed on the support member 1, so that the positioning rod 33 on the fixed mold part engages with the positioning groove 19 on the support member 1, thereby completing the installation of the fixed mold part. By rotating the lead screw 16, the moving block 17 moves along the lead screw 16. When the moving block 17 moves, it will synchronously drive the inserts 36 and the moving mold part to move until the moving mold part contacts the fixed mold part, and the raw material is injected into the fixed mold part. In the molding cavity between the mold part and the moving mold part, the raw material waits to solidify to form the cleaning nozzle. When the personnel need to demold, the lead screw 16 is rotated, which causes the moving block 17 to move along the lead screw 16. When the moving block 17 moves, it will simultaneously drive the insert 36 and the moving mold part to move, so that the moving mold part is separated from the fixed mold part, thereby exposing the cleaning nozzle. The cleaning nozzle is then removed from the molding cavity, thus completing the production of the cleaning nozzle. When the personnel need to replace the fixed mold part or the moving mold part, the fixed mold part and the moving mold part are pulled to separate the positioning rod 33 from the positioning groove 19 and to separate the insert 36 from the slot 18 on the moving block 17, so that the fixed mold part and the moving mold part can be removed for replacement.

[0032] Furthermore, in this utility model, in order to facilitate the collection of products produced by the mold, such as Figures 1-3 As shown, a through-type material guiding cavity 13 is formed on the support member 1. The material guiding cavity 13 is located below the fixed mold part and the moving mold part. A movable material storage member 2 is provided below the support member 1. The top of the material storage member 2 is open to form a material storage cavity 22.

[0033] In this embodiment, when the cleaning nozzle is removed from the molding cavity, it is received by the guide cavity 13 on the support member 1 and guided to fall into the storage cavity 22 on the storage member 2, thereby collecting the cleaning nozzle. After the cleaning nozzle is collected, the storage member 2 is pushed, so that the storage member 2 moves the cleaning nozzle to the position required by the personnel, making it convenient for the personnel to handle the cleaning nozzle.

[0034] Furthermore, in this utility model, regarding the aforementioned storage component 2, as follows: Figures 1-2 and Figure 4 As shown, the storage component 2 includes a storage box 21, which is located below the guide cavity 13, and a handle 23 is fixedly connected to the surface of the storage box 21. The storage cavity 22 is open and formed on the top of the storage box 21.

[0035] In this embodiment, before the cleaning nozzle is removed, the personnel pull the storage box 21 by the handle 23, so that the storage box 21 is moved below the support member 1 and the storage cavity 22 on the storage box 21 is below the guide cavity 13. The personnel remove the cleaning nozzle from the molding cavity, and the guide cavity 13 on the support member 1 receives the cleaning nozzle and guides it to fall into the storage cavity 22 on the storage box 21, thereby collecting the cleaning nozzle. After the cleaning nozzle is collected, the storage box 21 is pushed, so that the storage box 21 moves the cleaning nozzle to the position required by the personnel, making it convenient for the personnel to handle the cleaning nozzle.

[0036] Specifically, in one embodiment, regarding the aforementioned support member 1, as... Figures 1-3 As shown, the support member 1 includes a base frame 11, with two support rods 12 fixedly connected to both sides of the base frame 11 symmetrically, and a material guide cavity 13 formed on the base frame 11.

[0037] In this embodiment, the base frame 11 is supported by the support rod 12, and the lead screw 16 is supported by the base frame 11, thereby supporting the moving block 17. The moving mold part is placed between the two moving blocks 17, and the two inserts 36 on the moving mold part are respectively inserted into the slots 18 on the two moving blocks 17, thereby installing the moving mold part between the two moving blocks 17. Then, the fixed mold part is placed on the base frame 11, and the positioning rod 33 on the fixed mold part is engaged with the positioning groove 19 on the base frame 11, thereby completing the installation of the fixed mold part.

[0038] Regarding how lead screw 16 rotates, as follows: Figures 1-3 As shown, a motor 15 is fixedly connected to one side of the base frame 11, and the output end of the motor 15 is connected to the lead screw 16.

[0039] In this embodiment, when it is necessary to drive the lead screw 16 to rotate, the motor 15 works to drive the lead screw 16 to rotate, so that the moving block 17 moves along the lead screw 16.

[0040] To facilitate the connection of the storage box 21 to the base frame 11, such as Figures 1-4 As shown, the base frame 11 has a base frame 110 fixedly connected to both sides of the base frame 11. The opposite side of the two base frames 110 is recessed to form a sliding groove 111. The base frame 110 is located between two support rods 12, and the storage box 21 is slidably connected between the two sliding grooves 111.

[0041] In this embodiment, when personnel need to connect the storage box 21 to the base frame 11, they push the storage box 21 so that it slides between the two base frames 110 into the groove 111, making the connection between the storage box 21 and the base frame 11 more stable, and thus making the storage box 21 more stable when receiving the cleaning nozzle.

[0042] Furthermore, when personnel move the storage box 21, in order to facilitate the movement of the storage box 21, such as... Figure 1 , Figure 2 and Figure 4 As shown, a movable frame 24 is rotatably connected to the bottom of the storage box 21, and a movable wheel 25 is rotatably connected to the bottom of the movable frame 24.

[0043] In this embodiment, when personnel need to push the storage box 21, the movable frame 24 and the movable wheels 25 work together to make the storage box 21 easy to move, thereby improving the convenience of moving the storage box 21.

[0044] Specifically, in one embodiment, regarding the aforementioned mold-fixing portion, as... Figure 1 , Figure 2 , Figures 5-8 As shown, the fixed mold part includes a mold shell 31. One side of the mold shell 31 is open to form multiple mold holes 310, and the other side forms an injection hole 32. A guide groove 311 is formed inside the mold shell 31. The guide groove 311 is connected to the injection hole 32 and the multiple mold holes 310. Two positioning rods 33 are fixedly connected to the two symmetrical sides of the mold shell 31.

[0045] In this embodiment, when the fixed mold part needs to be installed, the mold shell 31 is placed on the base frame 11, and the positioning rod 33 on the mold shell 31 is engaged with the positioning groove 19 on the base frame 11, so that the mold shell 31 is installed on the base frame 11. When the moving block 17 drives the moving mold part to move, and the moving mold part comes into contact with the mold shell 31, the raw material is injected through the injection hole 32. Through the cooperation of the guide groove 311, the raw material is injected into the space between the mold hole 310 and the moving mold part. Wait for the raw material to solidify and form a cleaning nozzle. By moving the moving block 17, the moving mold part is moved away from the mold shell 31, so that the cleaning nozzle is exposed, and the cleaning nozzle can be demolded.

[0046] Furthermore, in this utility model, regarding the aforementioned moving mold portion, as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the moving mold part includes a movable plate 34, and a plurality of mold heads 35 are provided on the side of the movable plate 34 facing the mold shell 31, and the mold heads 35 are matched with the mold holes 310 one by one.

[0047] In this embodiment, the moving block 17 drives the moving plate 34 to move, which in turn drives the mold head 35 to move, so that the mold head 35 is inserted into the mold hole 310. After the raw material is injected between the mold head 35 and the mold hole 310, the raw material is allowed to solidify to form a cleaning nozzle.

[0048] After the equipment produces the cleaning nozzles, in order to facilitate the demolding of the cleaning nozzles, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the mold head 35 is slidably connected to the movable plate 34. A side frame 37 is fixedly connected to the side of the movable plate 34 away from the mold shell 31. A connecting plate 39 is fixedly connected to the side of the multiple mold heads 35 away from and close to the side frame 37. An electric push rod 38 is fixedly connected to the side frame 37. The telescopic end of the electric push rod 38 is connected to the connecting plate 39.

[0049] In this embodiment, after the mold head 35 moves to the outside of the mold hole 310, in order to facilitate the demolding of the cleaning nozzle, the electric push rod 38 operates, thereby driving the connecting plate 39 to move. The connecting plate 39 then drives the mold head 35 to move to the other side of the moving plate 34, thereby allowing the cleaning nozzle attached to the mold head 35 to detach, thus completing the demolding of the cleaning nozzle and causing it to fall into the guide cavity 13 for centralized collection.

[0050] 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.
