[0002] According to the published patent CN220638738U, the invention includes a fixed housing, two edge molds installed within the fixed housing, and a central mold. The fixed housing contains a moving component that drives the two edge molds closer to or further away from the central mold. The edge molds have a first heat-insulating cavity, and the central mold has a second heat-insulating cavity. This invention can control the temperature of the internal injection-molded preform through the internal liquid after injection molding, ensuring a relatively constant temperature and facilitating subsequent blow molding processes. However, it still has the following shortcomings:

[0003] The above-mentioned equipment can control the temperature of the internal injection preform to ensure a relatively constant temperature, which is convenient for subsequent injection molding operations. However, the injection mold may wear out after long-term use and needs to be disassembled and replaced. The above-mentioned equipment is not convenient to disassemble, which reduces the applicability of the device. Therefore, we propose a quick mold change buckle for plastic bottle injection molds. Utility Model Content

[0004] The purpose of this utility model is to provide a quick mold change buckle for plastic bottle injection molds. Through the disassembly mechanism and clamping mechanism, it solves the problem that existing equipment can control the temperature of the internal injection preform and ensure a relatively constant temperature, which is convenient for subsequent injection operations. However, the injection mold may wear out after long-term use and needs to be disassembled and replaced. The above-mentioned equipment is not convenient to disassemble during use, which reduces the applicability of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a quick mold change buckle for a plastic bottle injection mold, including a base, a support frame fixedly connected to the top outer wall of the base, a central mold fixedly connected to the inner wall of the support frame, and a disassembly mechanism provided on the outer wall of the base.

[0007] The disassembly mechanism includes several edge molds, each edge mold having a fixed block slidably connected to its outer wall. A rotating shaft is fixedly connected to the inner wall of each fixed block, and a worm gear is fixedly connected to the outer wall of the rotating shaft. A worm is rotatably connected to the inner wall of the fixed block near the worm gear. A turntable is fixedly connected to the outer wall of the rotating shaft away from the worm gear. Several arc-shaped grooves are formed on the inner wall of the turntable, and a limit shaft is slidably connected to the inner wall of each arc-shaped groove. A rod is rotatably connected to the outer wall of the limit shaft. Several positioning holes are formed on the inner wall of the fixed block near the rod. Several limit rods are fixedly connected to the inner wall of the fixed block near the turntable. Several support blocks are fixedly connected to the inner wall of the fixed block near the limit rods. A clamping mechanism is provided on the outer wall of the base.

[0008] Furthermore, the outer walls of several of the edge molds are slidably connected to the inner wall of the support frame, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and the outer wall of the insertion rod is slidably connected to the inner wall of the positioning hole.

[0009] Furthermore, the clamping mechanism includes a second support frame, the outer wall of which is fixedly connected to the top outer wall of the base.

[0010] Furthermore, a hydraulic rod is fixedly connected to the outer wall of the second support frame, and a sliding rod is slidably connected to the inner wall of the second support frame near the hydraulic rod. The bottom output end of the hydraulic rod is fixedly connected to the outer wall of the sliding rod.

[0011] Furthermore, a second slide rod is slidably connected to the inner wall of the end of the support frame away from the slide rod, and a limit shaft is fixedly connected to the outer wall of both the slide rod and the outer wall of the slide rod.

[0012] Furthermore, a fixed shaft is fixedly connected to the outer wall of the support frame two near the limiting shaft two, and a connecting rod is rotatably connected to the outer wall of the fixed shaft two.

[0013] Furthermore, the inner wall of the connecting rod is provided with several arc-shaped grooves, and the inner wall of the arc-shaped grooves is slidably connected to the outer wall of the limiting shaft.

[0014] Furthermore, the outer walls of the slide rod and the slide rod 2 are slidably connected to limit blocks, the outer walls of the limit blocks are fixedly connected to the outer walls of the fixing blocks, the outer walls of the slide rod and the slide rod 2 are fixedly connected to limit blocks 2, and the outer walls of the limit blocks 2 are fixedly connected to the outer walls of the fixing blocks.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a worm gear on a rotating shaft. When the equipment is in use, the rotation of the worm gear drives the worm wheel to rotate, causing the rotating shaft to rotate. The rotation of the rotating shaft drives the turntable to rotate, allowing multiple limiting shafts to slide simultaneously within the arc-shaped groove. The limiting shafts can then drive the insertion rods to move. When the multiple insertion rods are completely pulled out of the positioning holes, the edge mold can be removed from the fixing block for replacement. This design facilitates easy disassembly and replacement of the injection mold in the event of damage after prolonged use. Furthermore, the disassembly method of the device is simple and convenient, making it easy for users to operate.

[0017] 2. This utility model, by setting an arc-shaped groove on the connecting rod, allows the hydraulic rod to extend during equipment use, driving the sliding rod to slide within the support frame and towards the fixed shaft. The movement of the sliding rod causes the lower limiting block to move, bringing the left-side fixed block closer to the center. Simultaneously, the sliding rod's movement also drives the lower limiting shaft, which in turn causes the connecting rod to rotate around the fixed shaft, moving the upper limiting shaft towards the support frame. This allows for simultaneous adjustment of the injection mold's position during injection molding, ensuring a tight fit and preventing inaccurate mold alignment that could lead to injection failure. This improves the uniformity and stability of subsequent production processes.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a quick mold change buckle for a plastic bottle injection mold, including a base 1, a support frame 101 fixedly connected to the top outer wall of the base 1, a central mold 102 fixedly connected to the inner wall of the support frame 101, and a disassembly mechanism 2 provided on the outer wall of the base 1. The support frame 101 can support and limit the central mold 102 to prevent the central mold 102 from falling off.

[0029] The disassembly mechanism 2 includes several edge molds 201. Each edge mold 201 has a fixed block 202 slidably connected to its outer wall. A rotating shaft 203 is fixedly connected to the inner wall of each fixed block 202. A worm gear 204 is fixedly connected to the outer wall of the rotating shaft 203. The rotating shaft 203 can fix the position of the worm gear 204, allowing it to move only on the rotating shaft 203. Simultaneously, when the worm gear 204 rotates, it drives the rotating shaft 203 to rotate. A worm 205 is rotatably connected to the inner wall of the fixed block 202 near the worm gear 204. A turntable 206 is fixedly connected to the outer wall of the rotating shaft 203 away from the worm gear 204. Several arc-shaped grooves 209 are formed on the inner wall of the turntable 206. These arc-shaped grooves 209 prevent the limiting shaft 207 from jamming during movement, thus making the movement of the limiting shaft 207 smoother. The inner wall of 09 is slidably connected to a limiting shaft 207. The outer wall of the limiting shaft 207 is rotatably connected to an insertion rod 208. The inner wall of the fixing block 202 near the insertion rod 208 is provided with several positioning holes 212. When the insertion rod 208 is inserted into the positioning hole 212, the position of the edge mold 201 can be fixed so that it is installed on the fixing block 202. The inner wall of the fixing block 202 near the turntable 206 is fixedly connected to several limiting rods 210. The inner wall of the fixing block 202 near the limiting rods 210 is fixedly connected to several support blocks 211. The outer wall of the base 1 is provided with a clamping mechanism 3. The support blocks 211 can limit the movement trajectory of the insertion rod 208 to prevent the insertion rod 208 from being completely pulled out of the positioning hole 212 and then unable to be aligned with the insertion rod 208 and reinserted into the positioning hole 212.

[0030] The outer walls of several edge molds 201 are slidably connected to the inner wall of the support frame 101. The outer wall of the worm gear 205 meshes with the outer wall of the worm wheel 204. The outer wall of the insertion rod 208 is slidably connected to the inner wall of the positioning hole 212. The clamping mechanism 3 includes a second support frame 301, which can support the positions of the slide rods 303 and 304 and make them slide only within the second support frame 301 to prevent them from falling off. The outer wall of the second support frame 301 is fixedly connected to the top outer wall of the base 1. A hydraulic rod 302 is fixedly connected to the outer wall of the second support frame 301. A slide rod 303 is slidably connected to the inner wall of the second support frame 301 near the hydraulic rod 302. When the slide rod 303... During movement, the left-side limiting block 310 can be moved closer to the hydraulic rod 302, which in turn can move the fixing block 202 to move the edge mold 201 closer to the support frame 301. The bottom output end of the hydraulic rod 302 is fixedly connected to the outer wall of the slide rod 303. The inner wall of the support frame 301 away from the slide rod 303 is slidably connected to the slide rod 304. The outer walls of the slide rod 303 and the slide rod 304 are both fixedly connected to the limiting shaft 305. Through the limiting shaft 305, when the connecting rod 307 moves, it can drive the limiting shaft 305 to move in the arc groove 308, which can simultaneously drive the slide rod 303 and the slide rod 304 to move.

[0031] A fixed shaft 306 is fixedly connected to the outer wall of the support frame 2 301 near the limiting shaft 2 305. A connecting rod 307 is rotatably connected to the outer wall of the fixed shaft 2 306. Several arc-shaped grooves 308 are formed on the inner wall of the connecting rod 307. The inner wall of the arc-shaped grooves 308 is slidably connected to the outer wall of the limiting shaft 2 305. The arc-shaped grooves 308 can prevent the limiting shaft 2 305 from jamming during movement, thereby making the movement of the limiting shaft 2 305 more stable. The outer wall of the slide rod 303 and the slide rod 306 are also connected. The outer walls of 04 are all slidably connected to limit blocks 309. The outer walls of limit blocks 309 are fixedly connected to the outer walls of fixed blocks 202. The outer walls of slide rod 303 and slide rod 204 are all fixedly connected to limit blocks 210. The outer walls of limit blocks 210 are fixedly connected to the outer walls of fixed blocks 202. Since limit blocks 210 are fixed on slide rod 303 or slide rod 204, when slide rod 303 and slide rod 204 move, they can drive limit blocks 210 to move and cause fixed blocks 202 to move.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, and the edge mold 201 becomes damaged after prolonged use and needs to be disassembled and replaced, the worm gear 205 is rotated. The rotation of the worm gear 205 drives the worm wheel 204 to rotate, causing the rotating shaft 203 to rotate. The rotating shaft 203 then drives the turntable 206 to rotate, causing multiple limiting shafts 207 to slide simultaneously within the arc-shaped groove 209. The limiting shafts 207 drive the insertion rods 208 to move. When the multiple insertion rods 208 are completely pulled out of the positioning hole 212, the edge mold 201 can be removed from the fixing block 202 for replacement. The limiting rod 210 can fix the maximum rotation range of the turntable 206. The support block 211 allows the insertion rods 208 to be re-aligned and inserted into the positioning hole 212 after being completely pulled out, so that they can be re-aligned and inserted into the positioning hole 212 during the next reinstallation. Then, the hydraulic rod 302 is activated. 2. The extension can cause the slide bar 303 to slide within the support frame 2 301 and towards the fixed shaft 2 306. When the slide bar 303 moves, it can cause the lower limit block 2 310 to move, causing the left fixed block 202 to move towards the center. At the same time, when the slide bar 303 moves, it can cause the lower limit shaft 2 305 to move. When the limit shaft 2 305 moves, it can cause the connecting rod 307 to rotate around the fixed shaft 2 306, causing the upper limit shaft 2 305 to move towards the support frame 2 301. When the limit shaft 2 305 moves, it can cause the upper limit block 2 310 to move, causing the right fixed block 202 to converge towards the center. When the fixed blocks 202 are close together and wrap around the central mold 102, the plastic bottle injection operation can be performed by external tools. The limit block 309 can provide a certain support for the fixed block 202, making the movement of the fixed block 202 more stable.
