Description

Technical Field

[0001] This utility model relates to the field of glass bottle production, and in particular to a locking structure for the air guide block of a cooling air duct. Background Technology

[0002] After the glass bottle is formed in the mold, a high-intensity cooling airflow is sprayed into the inner cavity of the mold that carries the bottle preform. This allows the glass bottle to be cooled rapidly and evenly to a processable temperature, ensuring the bottle's strength, shape stability, and the smoothness of subsequent processes. The cooling airflow is usually supplied by an external air source and then delivered to the inside of a manifold located above the mold assembly. The manifold is equipped with a manifold block that divides the cooling airflow into two parts to supply two adjacent mold sets. Given that the manifold and manifold block are under high-intensity working conditions (enduring high-temperature radiation, airflow, and continuous mechanical impact), contaminants easily accumulate inside the manifold. Therefore, in the existing technology, the manifold block needs to be detachably connected to the inside of the manifold block with bolts to facilitate regular maintenance of the inside of the manifold block and the manifold block.

[0003] However, because the cooling airflow needs to frequently impact the distributor block, the distributor block will generate large vibrations when subjected to impacts. The vibration of the distributor block will be transmitted to the bolt through the rigid contact interface. Under the continuous vibration, the bolt preload will gradually decrease. Once the bolt preload caused by the vibration is completely lost, the distributor block will fall off. After the distributor block falls off, the cooling airflow will not need to impact the two adjacent sets of molds. As a result, the glass bottle will be cooled unevenly under the disordered cooling airflow after molding, resulting in problems such as insufficient rigidity or unstable shape of the glass bottle. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a locking structure for the air guide block of a cooling air duct. The purpose is to solve the technical problem that when the flow divider block is subjected to impact, it will generate large vibrations, and the vibration of the flow divider block will be transmitted to the bolt through the rigid contact interface. Under the continuous vibration, the bolt preload will gradually decrease, causing the flow divider block to detach.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A locking structure for a cooling air duct guide block includes a diverter seat. The diverter seat has a cooling air duct body and a partition air duct inside. The partition air duct is located above the cooling air duct body. The partition air duct has a mounting seat inside, which divides the partition air duct into two outlet channels. The bottom of the mounting seat has a guide block body facing the cooling air duct body. The mounting seat has fixing holes on both sides. The diverter seat has connecting holes on both sides that connect to the partition air duct. A fixing pin is slidably connected inside each connecting hole. One end of the fixing pin has a fixing end that inserts into an adjacent fixing hole. The other end of the fixing pin protrudes outside the connecting hole and has a movable block. Return springs are provided on both sides of the diverter seat, with one end of each return spring connected to an adjacent movable block.

[0007] When installing the air guide block, the mounting base is placed into the partition air duct of the distributor, so that the air guide block at the bottom of the mounting base faces the cooling air duct body below. The operator pulls the movable block away from the distributor. After the movable block moves, it will cause the fixed pin connected to it to slide along the connecting hole. The return spring is stretched under the pull of the movable block. The return spring stores elastic energy. At this time, the fixed holes on both sides of the mounting base need to be aligned with the connecting holes on both sides of the distributor. The operator releases the movable block at the same time, and the energy-stored return spring contracts, thereby driving the movable block towards the direction closer to the distributor. The movement of the pin allows the fixed end of the fixing pin to engage with the adjacent fixing hole, thus securing the mounting base. When the air guide block body vibrates due to the impact of the cooling airflow, the vibration energy attempts to be transmitted through the contact interface between the fixing pin and the fixing hole of the mounting base, causing the fixing pin to move slightly. The presence of the return spring provides a dynamic adaptive locking force, which, under the elasticity of the return spring, hinders this relative movement, compensates for the potential gap caused by vibration, and keeps the fixed end of the fixing pin engaged with the fixing hole, thereby avoiding the risk of the air guide block body falling off due to the detachment of the fastener.

[0008] Furthermore, in this application, the interior of the connecting socket is provided with a fastening inner sleeve, the fastening inner sleeve is elastic, and the fixing pin passes through the interior of the fastening inner sleeve, so that the inner edge of the fastening inner sleeve abuts against the outer edge of the fixing pin.

[0009] When the fixing pin is inserted into the fastening inner sleeve, the fixing pin expands the fastening inner sleeve made of elastic material, forcing the fastening inner sleeve to undergo radial elastic deformation. This elastic deformation causes the inner wall of the fastening inner sleeve to continuously and tightly wrap and press against the outer surface of the fixing pin, generating radial contact pressure. This increases the resistance to axial movement of the fixing pin within the connecting hole, making it more difficult for the fixing pin to undergo even slight displacement under high-intensity, high-frequency vibration and impact, thus ensuring the stability of the fixing end of the fixing pin during insertion. Furthermore, in this application, guide sliders are vertically provided on both sides of the partition duct, and the connecting hole penetrates one side of the adjacent guide slider. Guide grooves are provided on both sides of the mounting base, and the fixing holes on both sides of the mounting base are respectively located inside the guide grooves on both sides of the mounting base. The guide grooves on both sides of the mounting base slide in cooperation with the guide sliders on both sides of the partition duct.

[0010] When the mounting base is installed into the partition air duct, the guide grooves on both sides of the mounting base slide into the guide sliders on both sides of the partition air duct. The precise fit between the guide grooves and the guide sliders constrains the installation position of the mounting base, so that the mounting base is located on the center line of the partition air duct, dividing the partition air duct into two partition air ducts of the same size, ensuring that the cooling airflow can enter the two partition air ducts evenly.

[0011] Furthermore, in this application, limiting blocks are provided on both sides of the partition duct, and the limiting blocks are located below the guide slider, so that when the mounting seat slides into the partition duct, the bottom of the mounting seat abuts against the limiting blocks.

[0012] Furthermore, in this application, the mounting base has positioning pins on both sides of its bottom, and the limiting base has positioning holes on its top, with the positioning pins being inserted into the adjacent positioning holes.

[0013] Furthermore, in this application, the diverter seat has first mounting slots on both sides, the other end of the reset spring is connected to the adjacent first mounting slot, the movable block has a second mounting slot on one side, and one end of the reset spring is connected to the adjacent second mounting slot.

[0014] Furthermore, in this application, the first mounting groove has first latching protrusions on both sides, and the other end of the reset spring is inserted into the adjacent first mounting groove, so that the other end of the reset spring is engaged with the first latching protrusions on both sides of the adjacent first mounting groove. The second mounting groove has second latching protrusions on both sides, and one end of the reset spring is inserted into the adjacent second mounting groove, so that one end of the reset spring is engaged with the second latching protrusions on both sides of the adjacent second mounting groove.

[0015] Furthermore, in this application, a handle is provided on the other side of the movable block, and the handle is in the shape of an "n".

[0016] Furthermore, in this application, the air guide block body has guide slopes on both sides, and the guide slopes on both sides of the air guide block body face the interior of the two air outlet ducts respectively.

[0017] Furthermore, in this application, the fastening inner sleeve is made of a high-temperature resistant material.

[0018] This utility model has the following beneficial effects:

[0019] When installing the air guide block, the mounting base is placed into the partition air duct of the distributor, so that the air guide block at the bottom of the mounting base faces the cooling air duct body below. The operator pulls the movable block away from the distributor. After the movable block moves, it will cause the fixed pin connected to it to slide along the connecting hole. The return spring is stretched under the pull of the movable block. The return spring stores elastic energy. At this time, the fixed holes on both sides of the mounting base need to be aligned with the connecting holes on both sides of the distributor. The operator releases the movable block at the same time, and the energy-stored return spring contracts, thereby driving the movable block towards the direction closer to the distributor. The movement of the pin allows the fixed end of the fixing pin to engage with the adjacent fixing hole, thus securing the mounting base. When the air guide block body vibrates due to the impact of the cooling airflow, the vibration energy attempts to be transmitted through the contact interface between the fixing pin and the fixing hole of the mounting base, causing the fixing pin to move slightly. The presence of the return spring provides a dynamic adaptive locking force, which, under the elasticity of the return spring, hinders this relative movement, compensates for the potential gap caused by vibration, and keeps the fixed end of the fixing pin engaged with the fixing hole, thereby avoiding the risk of the air guide block body falling off due to the detachment of the fastener.

[0032] Reference Figures 1-7 In some specific embodiments, a locking structure for a cooling air duct guide block includes a diverter seat 1. The diverter seat 1 has a cooling air duct body 2 and a partition air duct 4 inside. The partition air duct 4 is located above the cooling air duct body 2. The cooling air duct body 2 is connected to an external air source. The partition air duct 4 has a mounting seat 5 inside, which divides the partition air duct 4 into two outlet baffles 7. The outlet baffles 7 are connected to adjacent molds. A guide block body 6 is located at the bottom of the mounting seat 5, facing the cooling air duct body 2. The mounting base 5 has fixed insertion holes 13 on both sides, and the diverter base 1 has connecting insertion holes 14 on both sides that connect to the dividing air duct 4. A fixed pin 15 is slidably connected inside the connecting insertion hole 14. One end of the fixed pin 15 has a fixed end 18, which is inserted into the adjacent fixed insertion hole 13. The other end of the fixed pin 15 protrudes outside the connecting insertion hole 14 and has a movable block 16 at the other end. The diverter base 1 has a return spring 19 on both sides, and one end of the return spring 19 is connected to the adjacent movable block 16.

[0033] With the above technical solution, when the air guide block body 6 is installed, the mounting base 5 is placed into the dividing air duct 4 of the distributor seat 1, so that the air guide block body 6 at the bottom of the mounting base 5 faces the cooling air duct body 2 below. The operator pulls the movable block 16 away from the distributor seat 1. After the movable block 16 moves, it will drive the fixed pin 15 connected to it to slide along the connecting hole 14. The return spring 19 is in an extended state under the pull of the movable block 16. The return spring 19 stores elastic energy. At this time, the fixed holes 13 on both sides of the mounting base 5 need to be aligned with the connecting holes 14 on both sides of the distributor seat 1. The operator releases the movable block 16 at the same time, and the energy-stored return spring 19 contracts, thereby driving the movable block 16 towards The device moves towards the direction of the diverter seat 1, so that the fixing end 18 of the fixing pin 15 is inserted into the adjacent fixing hole 13, thereby fixing the mounting seat 5. When the air guide block body 6 is impacted by the cooling airflow and vibrates, the vibration energy will try to be transmitted through the contact interface between the fixing pin 15 and the fixing hole 13 of the mounting seat 5, causing the fixing pin 15 to move slightly. The presence of the return spring 19 provides a dynamic adaptive locking force, which resists this relative movement under the elasticity of the return spring 19, compensates for the potential gap caused by vibration, and keeps the fixing end 18 of the fixing pin 15 inserted into the fixing hole 13, thereby avoiding the risk of the air guide block body 6 falling off due to the loosening of the fastener.

[0034] Reference Figures 4-7 In some specific embodiments, the inside of the connecting socket 14 is provided with a fastening inner sleeve 20. The fastening inner sleeve 20 is elastic, and the fixing pin 15 passes through the inside of the fastening inner sleeve 20, so that the inner edge of the fastening inner sleeve 20 abuts against the outer edge of the fixing pin 15.

[0035] Through the above technical solution, when the fixing pin 15 is inserted into the fastening inner sleeve 20, the fixing pin 15 will expand the fastening inner sleeve 20 made of elastic material, forcing the fastening inner sleeve 20 to undergo radial elastic deformation. This elastic deformation causes the inner wall of the fastening inner sleeve 20 to continuously and tightly wrap and press against the outer surface of the fixing pin 15, generating radial contact pressure, thereby strengthening the resistance of the fixing pin 15 to axial movement in the connecting hole 14. This makes it more difficult for the fixing pin 15 to produce small displacements even under high-intensity, high-frequency vibration and impact, thus ensuring the stability of the fixing end 18 of the fixing pin 15 when it is inserted.

[0036] Reference Figures 1-7 In some specific embodiments, guide sliders 9 are vertically provided on both sides of the partition duct 4, and connecting holes 14 penetrate one side of adjacent guide sliders 9. Guide grooves 8 are provided on both sides of the mounting base 5. The fixing holes 13 on both sides of the mounting base 5 are respectively located inside the guide grooves 8 on both sides of the mounting base 5. The guide grooves 8 on both sides of the mounting base 5 are slidably engaged with the guide sliders 9 on both sides of the partition duct 4.

[0037] With the above technical solution, when the mounting base 5 is installed into the partition air duct 4, the guide grooves 8 on both sides of the mounting base 5 slide and cooperate with the guide sliders 9 on both sides of the partition air duct 4 respectively. The precise cooperation between the guide grooves 8 and the guide sliders 9 constrains the installation position of the mounting base 5, so that the mounting base 5 is located on the center line of the partition air duct 4, dividing the partition air duct 4 into two partition air ducts 4 of the same size, ensuring that the cooling airflow can enter the two partition air ducts 4 evenly.

[0038] Reference Figure 6 In some specific embodiments, limiting blocks 10 are provided on both sides of the partition air duct 4. The limiting blocks 10 are located below the guide slider 9, so that when the mounting seat 5 slides into the partition air duct 4, the bottom of the mounting seat 5 abuts against the limiting blocks 10.

[0039] With the above technical solution, when the mounting base 5 slides vertically downward along the guide slider 9 through the guide groove 8 and is inserted into the bottom of the partition air duct 4, the bottom of the mounting base 5 abuts against the limiting bottom block 10, thereby limiting the installation depth of the mounting base 5 and preventing the mounting base 5 from sliding into the cooling air duct body 2; at the same time, it is also convenient to align the fixing socket 13 and the connecting socket 14, and improve the installation accuracy of the mounting base 5.

[0040] Furthermore, since the limiting block 10 supports the bottom of the mounting base 5, the bearing pressure on the fixing end 18 of the fixing pin 15 is reduced, thereby improving the service life of the fixing pin 15.

[0041] Reference Figures 5-6 In some specific embodiments, the mounting base 5 has positioning pins 12 on both sides of its bottom, and the limiting base block 10 has positioning holes 11 on its top. The positioning pins 12 are inserted into the adjacent positioning holes 11.

[0042] With the above technical solution, when the mounting base 5 slides down along the guide slider 9 and its bottom contacts the top of the limiting block 10, the positioning pin 12 at the bottom of the mounting base 5 is simultaneously inserted into the positioning hole 11 at the top of the limiting block 10, thereby facilitating the guidance of the installation position of the bottom of the mounting base 5 and preventing the mounting base 5 from being misaligned after insertion.

[0043] Reference Figures 1-7 In some specific embodiments, the diverter seat 1 has first mounting slots 21 on both sides, the other end of the return spring 19 is connected to the adjacent first mounting slot 21, and the movable block 16 has a second mounting slot 23 on one side, and one end of the return spring 19 is connected to the adjacent second mounting slot 23.

[0044] With the above technical solution, when the return spring 19 contracts or extends, since the other end of the return spring 19 is connected to the adjacent first mounting groove 21 and one end of the return spring 19 is connected to the adjacent second mounting groove 23, the positions of the two ends of the return spring 19 are limited, preventing the return spring 19 from leaving the mounting position.

[0045] Reference Figure 4 In some specific embodiments, the first mounting groove 21 has first locking protrusions 22 on both sides, and the other end of the return spring 19 is inserted into the adjacent first mounting groove 21, so that the other end of the return spring 19 is engaged with the first locking protrusions 22 on both sides of the adjacent first mounting groove 21. The second mounting groove 23 has second locking protrusions 24 on both sides, and one end of the return spring 19 is inserted into the adjacent second mounting groove 23, so that one end of the return spring 19 is engaged with the second locking protrusions 24 on both sides of the adjacent second mounting groove 23.

[0046] With the above technical solution, since the other end of the reset spring 19 is engaged with the first protrusions 22 on both sides of the adjacent first mounting groove 21, and one end of the reset spring 19 is engaged with the second protrusions 24 on both sides of the adjacent second mounting groove 23, the stability of the reset spring 19 is further enhanced, preventing the reset spring 19 from falling out of the installation position.

[0047] Reference Figure 4 In some specific embodiments, a handle 17 is provided on the other side of the movable block 16, and the handle 17 is in the shape of an "n".

[0048] With the above technical solution, when the operator needs to pull the movable block 16, the handle 17 is shaped like an "n", which allows the operator's fingers to be inserted into the handle 17, thereby increasing the contact area between the hand and the handle 17 and preventing the hand from being dislodged from the handle 17 due to the large elastic force of the return spring 19 when the movable block 16 is pulled.

[0049] Reference Figures 1-5 In some specific embodiments, the air guide block body 6 is provided with guide slopes 3 on both sides, and the guide slopes 3 on both sides of the air guide block body 6 face the interior of the two air outlet ducts 7 respectively.

[0050] Through the above technical solution, when the cooling airflow approaches the bottom of the air guide block body 6, the guide slopes 3 on both sides of the air guide block body are respectively directed towards the interior of the two air outlet baffles 7, thereby dividing the cooling airflow of the cooling air duct body 2 into two streams, which are then guided to the interior of the two air outlet baffles 7 in sequence; and the guide slopes 3 ensure that the flow path from the split point to the baffles on both sides is symmetrical and the flow resistance is symmetrical, which is beneficial to the balance of the initial cooling airflow distribution.

[0051] Reference Figure 4 In some specific embodiments, the fastening inner sleeve 20 is made of a high-temperature resistant material.

[0052] Through the above technical solution, since the temperature during glass forming is high, if the fastening inner sleeve 20 is made of ordinary material, in a high-temperature environment, ordinary elastic material will soften, creep (permanent deformation) or even melt, causing it to lose its elasticity; while high-temperature resistant materials (such as special silicone rubber, fluororubber, high-temperature polyurethane elastomer) can resist high temperature, so that the fastening inner sleeve 20 can continuously apply radial contact pressure to the fixing pin 15.

[0053] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
