Description

Technical Field

[0001] This utility model relates to the field of glass bottle molds, and in particular to a chip-proof structure for a mold clamp holder. Background Technology

[0002] On a glass bottle production line, the clamp frame is a component that supports the clamps. The clamp frame has a fixed plate at its bottom, and a vertical shaft is mounted on the mounting plate at its top. The clamp frame has a detachable mounting plate at its top, and one end of the vertical shaft extends out of the mounting plate. There are two clamps, and one end of each clamp is fitted onto the vertical shaft, allowing the two clamps to be rotatably connected to the vertical shaft. Each of the two clamps has half of a glass bottle forming mold on one side. A drive device pushes each clamp to rotate around the vertical shaft, thereby opening and closing the glass bottle forming mold.

[0003] To improve the rigidity and vibration resistance of the connection between the vertical shaft and the mounting plate, existing technology typically adds a retaining ring to the axial protruding end of the vertical shaft through the mounting plate. The retaining ring rests against the top of the mounting plate to prevent the mounting plate from loosening or swaying during high-frequency opening and closing. However, during the thermoforming of glass bottles, the glass bottle forming mold is continuously exposed to a high-temperature environment, and molten glass will splash out glass fragments. Since the retaining ring is installed close to the working area of ​​the glass bottle forming mold, glass fragments will splash onto the surface of the retaining ring and into the joint gap between it and the vertical shaft. After the molten glass slag seeps into the gap between the retaining ring and the vertical shaft, it solidifies to form a physical bond, making the retaining ring and the vertical shaft a single unit. When changing production or when the clamp needs to be replaced for equipment maintenance, it is difficult to disassemble the retaining ring. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a chip-proof structure for a mold clamp holder. The purpose is to solve the technical problem that, because the fixed ring is installed close to the working area of ​​the glass bottle forming mold, glass fragments will splash onto the surface of the fixed ring and into the joint gap between the fixed ring and the vertical shaft. After the glass slag seeps into the gap between the fixed ring and the vertical shaft, it solidifies to form a physical bond, making the fixed ring and the vertical shaft a single unit. When the clamp needs to be replaced during production change or equipment maintenance, it is difficult to disassemble the fixed ring.

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

[0006] A chip-prevention structure for a mold clamp holder includes a clamp holder body and two clamp bodies. The clamp holder body has a fixing plate at its bottom and a vertical shaft at its top. One end of each clamp body is rotatably connected to the vertical shaft. A mounting plate is detachably connected to the top of the clamp holder body. The mounting plate has an internal mounting groove. One end of the vertical shaft has a protruding end that protrudes beyond the mounting groove. A fixing ring is fitted onto the protruding end. Locking holes are formed on both sides of the fixing ring, communicating with the interior of the fixing ring. A locking bolt is threaded into the locking hole and abuts against the protruding end. A mounting seat is provided at the top of the fixing ring, and an installation cavity is formed at the top of the mounting seat. A fixing socket is inserted into the installation cavity. A chip catcher is provided at the top of the fixing socket, and a chip catcher cavity is formed at the top of the chip catcher.

[0007] When the two clamp bodies are installed outside the vertical shaft, the mounting plate is installed on the top of the clamp frame body, so that the protruding end of the vertical shaft protrudes out of the mounting groove of the mounting plate. The retaining ring is sleeved on the outside of the protruding end, and the locking bolt is screwed into the locking hole. The locking bolt abuts against the protruding end, so that the retaining ring restricts the position of the mounting plate. When high-temperature glass fragments splash from the mold body, the top of the retaining ring is equipped with a setting seat, and the top of the setting seat is equipped with a chip catcher. The chip catcher cavity of the chip catcher blocks the falling fragments, so that the glass fragments cannot contact the key mating surface between the retaining ring and the protruding end. This completely solves the problem of the protruding end and the retaining ring sticking together due to glass fragments. Furthermore, when the chip catcher cavity is full, the glass fragments can be cleaned by pulling out the fixing socket, avoiding equipment shutdown and disassembly.

[0008] Furthermore, in this application, multiple connecting grooves are provided on both sides of the mounting cavity, a fixing spring is provided inside the connecting groove, a connecting block is provided inside one end of the fixing spring, a locking ball is provided at one end of the connecting block, the locking ball protrudes from the interior of the mounting cavity, and multiple locking holes are provided on both sides of the fixing socket, the locking holes engaging with adjacent locking balls.

[0009] When the fixed socket is inserted axially along the mounting cavity, the outer wall of the fixed socket presses against the surface of the locking ball, forcing the locking ball and connecting block to retract into the connecting groove. This causes the fixing spring to be in a contracted state. When the fixed socket is inserted until the locking hole and the connecting groove are aligned, the fixing spring extends, pushing the connecting block and the locking ball radially outward. This allows the locking hole of the fixed socket to engage with the adjacent locking ball, thus facilitating the fixation of the chip collector and preventing it from detaching from the mounting cavity due to vibration. When the chip collector needs to be disassembled for cleaning, the operator pulls the chip collector, making the pulling force greater than the spring force of the fixing spring, forcing the locking ball to disengage from the locking hole, thus disassembling the chip collector.

[0010] Furthermore, in this application, two first locking posts are provided on both sides of the inner side of the connecting groove, and the two first locking posts are engaged with the other end of the fixing spring. Second locking posts are provided on both sides of the connecting block, and the second locking posts on both sides of the connecting block are engaged with the inner side of one end of the fixing spring.

[0011] When the fixed spring extends, it engages with the other end of the fixed spring through two first locking pins, and the second locking pins on both sides of the connecting block engage with the inside of one end of the fixed spring, so that the fixed spring remains in the connecting groove during deformation, thereby preventing the fixed spring from detaching from the connecting groove.

[0012] Furthermore, in this application, the bottom of the chip receiving frame is provided with a plurality of fastening pins, and the top of the mounting base is provided with a plurality of fastening holes, and the plurality of fastening pins are respectively inserted into the plurality of fastening holes.

[0013] Furthermore, in this application, a fastening sleeve is provided on the outside of the fastening pin, the fastening sleeve is elastic, and the fastening sleeve engages with the adjacent fastening hole.

[0014] Furthermore, in this application, the top of the chip receiving frame is provided with a handle, and the handle is n-shaped.

[0015] Furthermore, in this application, the mounting plate has a first fixing hole inside, and the clamp bracket body has a second fixing hole on its top. A fixing bolt passes through the first fixing hole, and the fixing bolt is threaded into the second fixing hole.

[0016] Furthermore, in this application, the top of the clamp holder body is provided with multiple positioning holes, and the bottom of the mounting plate is provided with multiple positioning pins, and the multiple positioning pins are respectively inserted into the multiple positioning holes.

[0017] Furthermore, in this application, one end of the clamp body is provided with a connecting arm, the connecting arm has a rotating setting groove inside, the rotating setting groove has a detachable rotating cylinder inside, the rotating cylinder is sleeved on the outside of the vertical shaft, so that the inside of the rotating cylinder is rotatably connected to the vertical shaft.

[0018] Furthermore, in this application, the connecting arm has a first mounting hole on both sides that connects to the rotating mounting groove, and the rotating cylinder has a second mounting hole on both sides. A mounting bolt passes through the first mounting hole, and the mounting bolt is threaded into the adjacent second mounting hole.

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

[0020] When the two clamp bodies are installed outside the vertical shaft, the mounting plate is installed on the top of the clamp frame body, so that the protruding end of the vertical shaft protrudes out of the mounting groove of the mounting plate. The retaining ring is sleeved on the outside of the protruding end, and the locking bolt is screwed into the locking hole. The locking bolt abuts against the protruding end, so that the retaining ring restricts the position of the mounting plate. When high-temperature glass fragments splash from the mold body, the top of the retaining ring is equipped with a setting seat, and the top of the setting seat is equipped with a chip catcher. The chip catcher cavity of the chip catcher blocks the falling fragments, so that the glass fragments cannot contact the key mating surface between the retaining ring and the protruding end. This completely solves the problem of the protruding end and the retaining ring sticking together due to glass fragments. Furthermore, when the chip catcher cavity is full, the glass fragments can be cleaned by pulling out the fixing socket, avoiding equipment shutdown and disassembly. Attached Figure Description

[0036] Reference Figures 1-10 In some specific embodiments, a chip-proof structure for a mold clamp holder includes a clamp holder body 3 and two clamp bodies 2. A fixing plate 4 is provided at the bottom of the clamp holder body 3, and a vertical shaft 5 is provided at the top of the fixing plate 4. One end of each clamp body 2 is rotatably connected to the vertical shaft 5. A mounting plate 6 is detachably connected to the top of the clamp holder body 3. A mounting groove 12 is provided inside the mounting plate 6. One end of the vertical shaft 5 has a protruding end 13 that protrudes beyond the mounting groove 12. The set includes a fixing ring 14, with locking holes 15 on both sides of the fixing ring 14. The locking holes 15 are connected to the interior of the fixing ring 14, and locking bolts 16 are threaded into the locking holes 15. The locking bolts 16 abut against the protruding end 13. The top of the fixing ring 14 is provided with a mounting seat 17, and the top of the mounting seat 17 is provided with a mounting cavity 18. A fixing socket 31 is inserted into the mounting cavity 18. The top of the fixing socket 31 is provided with a chip collector 25, and the top of the chip collector 25 is provided with a chip collecting cavity 26.

[0037] With the above technical solution, when the two clamp bodies 2 are installed outside the vertical shaft 5, the mounting plate 6 is installed on the top of the clamp frame body 3, so that the protruding end 13 of the vertical shaft 5 protrudes out of the mounting groove 12 of the mounting plate 6, the fixing ring 14 is sleeved on the protruding end 13, the locking bolt 16 is screwed into the locking hole 15, and the locking bolt 16 abuts against the protruding end 13, so that the fixing ring 14 restricts the position of the mounting plate 6. When high-temperature glass fragments splash from the mold body 1, since the top of the fixing ring 14 is provided with a setting seat 17, and the top of the setting seat 17 is provided with a chip receiving frame 25, the chip receiving cavity 26 of the chip receiving frame 25 blocks the falling fragments, so that the glass fragments cannot contact the key mating surface between the fixing ring 14 and the protruding end 13, completely solving the problem of the protruding end 13 and the fixing ring 14 sticking together due to glass fragments. Furthermore, when the chip receiving cavity 26 is full, the fixing socket 31 can be pulled out to clean the glass fragments, avoiding equipment shutdown and disassembly.

[0038] Furthermore, the area of ​​the mounting base 17 and the chip collector 25 can completely cover or be larger than the fixing ring 14, thereby further increasing the shielding area of ​​the fixing ring 14.

[0040] Through the above technical solution, the clamp body 2 will vibrate during operation. This vibration will be transmitted to the chip collector 25, causing the chip collector 25 to detach from the mounting cavity 18. Therefore, when the fixing socket 31 is inserted axially along the mounting cavity 18, the outer wall of the fixing socket 31 presses against the spherical surface of the locking ball 24, forcing the locking ball 24 and the connecting block 22 to retract into the connecting groove 19, so that the fixing spring 20 is in a contracted state. When the fixing socket 31 is inserted until the locking hole 32 is aligned with the connecting groove 19, the fixing... When the spring 20 extends, it pushes the connecting block 22 and the locking ball 24 to pop out radially, so that the locking hole 32 of the fixed socket 31 engages with the adjacent locking ball 24, thereby facilitating the fixing of the chip rack 25 and preventing the chip rack 25 from dislodging from the installation cavity 18 due to vibration. When the chip rack 25 needs to be disassembled for cleaning, the operator pulls the chip rack 25, so that the pulling force is greater than the elastic force of the fixed spring 20, forcing the locking ball 24 to disengage from the locking hole 32, so that the chip rack 25 is disassembled.

[0041] Reference Figure 8 In some specific embodiments, two first locking posts 21 are provided on both sides of the inside of the connecting groove 19. The two first locking posts 21 are engaged with the other end of the fixing spring 20. Second locking posts 23 are provided on both sides of the connecting block 22. The second locking posts 23 on both sides of the connecting block 22 are engaged with the inside of one end of the fixing spring 20.

[0042] With the above technical solution, when the fixed spring 20 is extended, the two first locking posts 21 are engaged with the other end of the fixed spring 20, and the second locking posts 23 on both sides of the connecting block 22 are engaged with the inside of one end of the fixed spring 20, so that the fixed spring 20 is kept in the connecting groove 19 during the deformation process, thereby preventing the fixed spring 20 from falling out of the connecting groove 19.

[0043] Reference Figures 5-6 In some specific embodiments, the bottom of the chip collector 25 is provided with a plurality of fastening pins 28, and the top of the mounting base 17 is provided with a plurality of fastening holes 30, and the plurality of fastening pins 28 are respectively inserted into the plurality of fastening holes 30.

[0044] With the above technical solution, when the fixed socket 31 is plugged into the mounting cavity 18, the multiple fastening pins 28 at the bottom of the chip collector 25 are respectively plugged into the multiple fastening holes 30, thereby facilitating the positioning of the fixed socket 31.

[0045] Reference Figures 5-6 In some specific embodiments, a fastening sleeve 29 is provided on the outside of the fastening pin 28. The fastening sleeve 29 is elastic and engages with the adjacent fastening hole 30.

[0046] With the above technical solution, when the fixed socket 31 is inserted into the mounting cavity 18, the fastening sleeves 29 of the multiple fastening pins 28 are respectively inserted into the multiple fastening holes 30, thereby strengthening the firmness of the fixed socket 31 and preventing the fixed socket 31 from detaching from the mounting cavity 18 under vibration.

[0047] Reference Figures 5-6 In some specific embodiments, the top of the chip receiving frame 25 is provided with a handle 27, which is n-shaped.

[0048] Through the above technical solution, the two ends of the n-shaped handle 27 are vertically fixed to the top of the chip collection frame 25, and the arched handle in the middle spans the two ends to form a closed force-bearing frame, so that when the operator needs to pull out the chip collection frame 25 through the handle 27, the operator has sufficient contact area with the handle 27.

[0049] Reference Figures 1-4 In some specific embodiments, the mounting plate 6 has a first fixing hole 8 inside, and the clamp bracket body 3 has a second fixing hole 7 on the top. A fixing bolt 9 passes through the first fixing hole 8 and is threaded into the second fixing hole 7.

[0050] With the above technical solution, when the mounting plate 6 is installed on the top of the clamp frame body 3, the fixing bolt 9 passes through the first fixing hole 8, so that the fixing bolt 9 is threadedly engaged with the second fixing hole 7, thereby facilitating the fixing of the position of the mounting plate 6.

[0051] Reference Figures 1-4 In some specific embodiments, the top of the clamp holder body 3 is provided with multiple positioning holes 11, and the bottom of the mounting plate 6 is provided with multiple positioning pins 10, which are respectively inserted into the multiple positioning holes 11.

[0054] With the above technical solution, the clamp body 2 rotates frequently during operation. Therefore, after prolonged use, the rotation setting groove 34 of its connecting arm 33 will wear out, requiring replacement of the clamp body 2, which is costly. Therefore, when the clamp body 2 is installed, the rotating cylinder 37 of the connecting arm 33 is fitted over the outside of the vertical shaft 5, so that the inside of the rotating cylinder 37 is rotatably connected to the vertical shaft 5. Thus, when the drive device drives the clamp body 2 to rotate, the rotating cylinder 37 replaces the rotation setting groove 34 of the connecting arm 33 to rotate, so that the rotating cylinder 37 only needs to be replaced when damaged, thereby reducing the maintenance cost of the clamp body 2.

[0055] Reference Figures 1-10 In some specific embodiments, the connecting arm 33 has first mounting holes 35 on both sides of the connecting arm 33, which are connected to the rotating mounting groove 34, and the rotating cylinder 37 has second mounting holes 38 on both sides. Mounting bolts 36 are inserted into the first mounting holes 35, and the mounting bolts 36 are threaded into the adjacent second mounting holes 38.

[0056] With the above technical solution, when the rotating cylinder 37 is installed, the mounting bolt 36 passes through the first mounting hole 35 and engages with the adjacent second mounting hole 38 by thread, thereby facilitating the fixing of the position of the rotating cylinder 37.
