Description

Technical Field

[0001] This utility model relates to the field of glass bottle molds, and in particular to a tool for cleaning the vent holes of a mold. Background Technology

[0002] During the glass bottle manufacturing process, the mold is filled with gas. This gas comes from the air inside the mold and the gas generated when the mold comes into contact with the molten glass. The vents in the mold help these gases to escape smoothly, preventing them from getting trapped inside the formed glass bottle and forming bubbles or defects. However, when producing irregularly shaped bottles, the mold needs to be continuously optimized due to the special shape of the bottles. Before optimization, the vents may become clogged. For example, when producing glass bottles with decorative protrusions, the mold has recesses that match the decorative protrusions. If the heat retention capacity of the recesses in the mold is insufficient, the decorative protrusions cool faster. These decorative protrusions will form shadow areas in the recesses of the mold, causing the molten glass to become less fluid. Molten glass with poor fluidity is not easy to flow to the vents. As more gas gets trapped, the pressure near the decorative protrusions will gradually accumulate, which will cause the flow direction of the molten glass to change. Some of the molten glass will be pushed to vents in other parts of the mold. Once the molten glass flows into the vent, it will solidify there. The solidified glass blocks will block the vents, so the blocked vents need to be cleaned manually.

[0003] Currently, cleaning the vents mainly relies on manually driving a hammer to impact the glass block. However, since the force of manual driving cannot be controlled, if the impact force is too great, it will damage the vents, making cleaning the vents inconvenient. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tool for cleaning the vent holes of a mold. The purpose is to solve the technical problem that the force of manually driving the impact pin cannot be controlled. If the impact force is too large, it will damage the vent holes and make cleaning the vent holes inconvenient.

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

[0006] A tool for cleaning vent holes in a mold includes a support rod, an adjusting rod inside the support rod, a movable cavity inside the adjusting rod, an impact spring inside the movable cavity, a strike pin at one end of the impact spring, the strike pin slidingly engaging with the movable cavity, a first connecting groove communicating with the movable cavity on one side of the adjusting rod, a second connecting groove communicating with the first connecting groove on one side of the support rod, a connecting block on one side of the strike pin, the connecting block slidingly engaging with the first and second connecting grooves, a fixing plate on one side of the connecting block, the fixing plate being located outside the support rod, a movable end at one end of the fixing plate, the movable end being elastic, a fixing block on one side of the movable end, and a fixing slot communicating with the second connecting groove on one side of the support rod, the fixing block engaging with the fixing slot.

[0007] When it is necessary to clean the glass block in the vent of the mold, pull down the fixing plate, which causes the ejector pin to move downward. The ejector pin drives the impact spring to retract. When the fixing block at the movable end slides to correspond with the fixing slot, the fixing block will engage with the fixing slot due to the elasticity of the movable end, thus fixing the initial position of the ejector pin. After the fixing plate is released, the elastic force of the impact spring pushes the ejector pin forward quickly, generating the impact force required to clean the glass block. Since the position of each contraction and extension of the impact spring is similar, the impact force of the ejector pin is precisely controlled each time it cleans the glass block, ensuring the consistency of the cleaning force and thus protecting the vent of the mold.

[0008] Furthermore, in this application, one end of the firing pin protrudes outside the movable cavity, and one end of the firing pin is provided with an impact head.

[0009] By setting an impact head at one end of the impact pin, the contact area between the impact pin and the glass block in the vent hole can be increased, improving the cleaning effect. At the same time, the impact head can be replaced or adjusted according to the shape and size of the vent hole of different molds, improving the applicability of the tool.

[0010] Furthermore, in this application, the impact head is cone-shaped.

[0011] The tip of the cone can be precisely positioned and enter the vent hole, while the gradually increasing diameter can effectively remove glass blocks from the hole. Furthermore, the progressive contact of the cone can reduce damage to the vent hole and extend the service life of the mold.

[0012] Furthermore, in this application, one end of the impact head is provided with a mounting base, and one end of the impact pin is provided with a mounting groove, wherein the mounting base and the mounting groove are threaded together.

[0013] Furthermore, in this application, the interior of the movable cavity is provided with a first mounting post, which is internally connected to the other end of the impact spring, and the other end of the firing pin is provided with a second mounting post, which is internally connected to one end of the impact spring.

[0014] Furthermore, in this application, the first mounting post has first locking protrusions on both sides, and the first locking protrusions on both sides of the first mounting post are internally engaged with the other end of the impact spring. The second mounting post has second locking protrusions on both sides, and the second locking protrusions on both sides of the second mounting post are internally engaged with one end of the impact spring.

[0015] Furthermore, in this application, the other end of the fixing plate is provided with a pressing end.

[0016] Furthermore, in this application, the support rod has an adjustment cavity inside, the adjustment rod slides in the adjustment cavity, a first fixing hole is provided on one side of the support rod, the first fixing hole communicates with the adjustment cavity, and a plurality of second fixing holes are provided on the other side of the adjustment rod, a fixing bolt passes through the first fixing hole, and the fixing bolt is threaded in any of the second fixing holes.

[0017] Furthermore, in this application, guide grooves are provided on both sides of the adjusting rod, and guide sliders are provided on both sides of the adjusting cavity. The guide sliders on both sides of the adjusting cavity slide in cooperation with the guide grooves on both sides of the adjusting rod.

[0018] Furthermore, in this application, the impact head is made of a wear-resistant material.

[0019] This utility model has the following beneficial effects:

[0020] When it is necessary to clean the glass block in the vent of the mold, pull down the fixing plate, which causes the ejector pin to move downward. The ejector pin drives the impact spring to retract. When the fixing block at the movable end slides to correspond with the fixing slot, the fixing block will engage with the fixing slot due to the elasticity of the movable end, thus fixing the initial position of the ejector pin. After the fixing plate is released, the elastic force of the impact spring pushes the ejector pin forward quickly, generating the impact force required to clean the glass block. Since the position of each contraction and extension of the impact spring is similar, the impact force of the ejector pin is precisely controlled each time it cleans the glass block, ensuring the consistency of the cleaning force and thus protecting the vent of the mold.

[0031] Reference Figures 1-5 In some specific embodiments, a tool for cleaning the vent holes of a mold includes a support rod 1. An adjusting rod 4 is provided inside the support rod 1. A movable cavity 11 is opened inside the adjusting rod 4. An impact spring 16 is provided inside the movable cavity 11. One end of the impact spring 16 is provided with a striking pin 12, which slides in cooperation with the movable cavity 11. A first connecting groove 9 communicating with the movable cavity 11 is opened on one side of the adjusting rod 4. A second connecting groove 3 communicating with the first connecting groove 9 is opened on one side of the support rod 1. A connecting block 21 is provided on one side of the striking pin 12, which slides in cooperation with the first connecting groove 9 and the second connecting groove 3. A fixing plate 22 is provided on one side of the connecting block 21, located outside the support rod 1. A movable end 23 is provided at one end of the fixing plate 22. The movable end 23 is elastic. A fixing block 24 is provided on one side of the movable end 23. A fixing slot 26 communicating with the second connecting groove 3 is opened on one side of the support rod 1, and the fixing block 24 engages with the fixing slot 26.

[0032] With the above technical solution, when it is necessary to clean the glass block of the mold's vent hole, the fixing plate 22 is pulled down, causing the fixing plate 22 to drive the impact pin 12 to move downward. The impact pin 12 drives the impact spring 16 to retract. When the fixing block 24 of the movable end 23 slides to correspond with the fixing slot 26, due to the elasticity of the movable end 23, the fixing block 24 will engage with the fixing slot 26, thereby fixing the initial position of the impact pin 12. After the fixing plate 22 is released, the elastic force of the impact spring 16 pushes the impact pin 12 forward quickly, generating the impact force required to clean the glass block. Since the position of each contraction and extension of the impact spring 16 is similar, the impact force of the impact pin 12 is precisely controlled each time it cleans the glass block, ensuring the consistency of the cleaning force, thereby protecting the vent hole of the mold.

[0033] It should be noted that when selecting a suitable impact spring 16, the elasticity of the impact spring 16 must be sufficient to impact the glass block, but not to damage the venting holes of the mold.

[0034] Reference Figures 1-4In some specific embodiments, one end of the firing pin 12 protrudes outside the movable cavity 11, and one end of the firing pin 12 is provided with an impact head 14.

[0035] By using the above technical solution, by setting an impact head 14 at one end of the impact pin 12, the contact area between the impact pin 12 and the glass block in the vent hole can be increased, thereby improving the cleaning effect. At the same time, the impact head 14 can be replaced or adjusted according to the shape and size of the vent hole of different molds, thus improving the applicability of the tool.

[0036] Reference Figures 1-4 In some specific embodiments, the impact head 14 is cone-shaped.

[0037] Through the above technical solution, the tip of the cone can be precisely positioned and enter the vent hole, while the gradually increasing diameter can effectively remove glass blocks from the hole. Furthermore, the progressive contact of the cone can reduce damage to the vent hole and extend the service life of the mold.

[0038] Reference Figure 4 In some specific embodiments, one end of the impact head 14 is provided with a mounting base 15, and one end of the impact pin 12 is provided with a mounting groove 13, with the mounting base 15 and the mounting groove 13 threadedly engaged.

[0039] With the above technical solution, when the impact head 14 is worn or a different shape of impact head 14 is required, the old impact head 14 can be easily removed and replaced with a new or different shaped impact head 14. This greatly improves the applicability of the tool, enabling it to adapt to different mold venting hole cleaning needs. At the same time, since the worn impact head 14 can be replaced, the service life of the entire tool is extended and the cost of use is reduced.

[0040] Reference Figures 4-5 In some specific embodiments, the interior of the movable cavity 11 is provided with a first mounting post 17, which is internally connected to the other end of the impact spring 16, and the other end of the striker 12 is provided with a second mounting post 19, which is internally connected to one end of the impact spring 16.

[0041] Through the above technical solution, the first mounting post 17 is fixed in the movable cavity 11, providing a stable support point for the impact spring 16. The second mounting post 19 is connected to the impact pin 12 and can move with the impact pin 12 while maintaining connection with the impact spring 16. This bidirectional fixing method can ensure that the impact spring 16 maintains the correct position and direction during repeated compression and release, thereby improving the stability and reliability of the impact pin 12.

[0042] Reference Figures 4-5In some specific embodiments, the first mounting post 17 is provided with first locking protrusions 18 on both sides, and the first locking protrusions 18 on both sides of the first mounting post 17 are internally engaged with the other end of the impact spring 16. The second mounting post 19 is provided with second locking protrusions 20 on both sides, and the second locking protrusions 20 on both sides of the second mounting post 19 are internally engaged with one end of the impact spring 16.

[0043] With the above technical solution, the first mounting post 17 and the second mounting post 19 are respectively set at both ends of the impact spring 16. This design can more firmly fix the impact spring 16 and prevent it from loosening or falling off during use.

[0044] Reference Figures 4-5 In some specific embodiments, the other end of the fixing plate 22 is provided with a pressing end 25.

[0045] With the above technical solution, when it is necessary to clean the mold vent hole, the operator can control the movement and impact force of the impact pin 12 by pressing the push end 25. This design not only improves the cleaning efficiency, but also increases the comfort and safety of operation.

[0047] Through the above technical solution, the adjustment cavity 2 inside the support rod 1 slides with the adjustment rod 4, allowing the adjustment rod 4 to slide inside the support rod 1 to achieve length adjustment. The first fixing hole 6 on one side of the support rod 1 and the multiple second fixing holes 8 on the other side of the adjustment rod 4 work together. By passing the fixing bolt 7 through the first fixing hole 6 and threadedly connecting it to the selected second fixing hole 8, the adjustment rod 4 can be fixed in the required position. This allows the operator to select the appropriate length of the adjustment rod 4 according to the depth of the mold vent hole, improving the applicability of the tool and the cleaning effect.

[0048] Reference Figures 1-3 In some specific embodiments, guide grooves 10 are provided on both sides of the adjusting rod 4, and guide sliders 5 are provided on both sides of the adjusting cavity 2. The guide sliders 5 on both sides of the adjusting cavity 2 are slidably engaged with the guide grooves 10 on both sides of the adjusting rod 4.

[0049] Through the above technical solution, the guide grooves 10 on both sides of the adjusting rod 4 and the guide sliders 5 on both sides of the adjusting cavity 2 can slide together to play a guiding and limiting role, effectively preventing the adjusting rod 4 from deviating or rotating during the sliding process, and ensuring that the adjusting rod 4 slides smoothly along the predetermined track in the adjusting cavity 2.

[0050] Reference Figures 1-5 In some specific embodiments, the impact head 14 is made of wear-resistant material.

[0051] Through the above technical solutions, the use of wear-resistant materials not only improves the durability of the tool, but also maintains the shape and size stability of the impact head 14, ensuring the consistency of the cleaning effect.
