Description

Technical Field

[0001] This utility model relates to the field of eye drop bottle mold technology, and in particular to a mold suitable for adapting to eye drop bottles of different specifications and shapes. Background Technology

[0002] An eye drop bottle mold is a specialized tool used to mold eye drop bottles through injection molding and injection blow molding processes. Its core function is to shape molten plastic into a standard eye drop bottle shape using a pre-set cavity and core structure, while ensuring the bottle's precision, sealing, and surface quality.

[0003] As packaging containers that come into direct contact with the liquid medicine, the production of eye drop bottles needs to balance standardization and diversity. In the traditional production model, the mold and the bottle shape correspond one-to-one, which is difficult to adapt to changes in the industry. Therefore, there is a need for a mold that can adapt to eye drop bottles of different specifications and shapes, so that the production of new bottle shapes can be carried out without redesigning the overall structure, thereby improving production efficiency.

[0004] Early eye drop bottle molds were single, fixed structures, mainly consisting of an integral cavity, an integral core, and a manual demolding mechanism. These parts were rigidly connected by welding or bolts. Since the mold could only produce one size of bottle, different bottle types required new molds, increasing mold costs. Furthermore, the long mold changeover time reduced work efficiency. To address these issues, existing adjustable molds employ a modular design, breaking down the cavity into replaceable main modules to reduce mold costs and shorten changeover time. However, in practical use, these replaceable main modules cannot be quickly adjusted according to the bottle's height and diameter, making them unsuitable for various sizes. Moreover, the reliance on manual verification of module alignment accuracy fails to meet user needs. Utility Model Content

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.

[0019] Reference Figure 3 , Figure 4 and Figure 5 The present invention provides an embodiment of a mold suitable for adapting to eye drop bottles of different specifications and shapes, comprising a frame 1, an adjustment mechanism 2 provided inside the frame 1, the adjustment mechanism 2 being used to adjust the height and diameter of the mold production area, a housing 3 being fixedly connected to the top of the frame 1, and a fixing mechanism 4 being provided inside the housing 3, the fixing mechanism 4 being used to clamp molds of different sizes. Adjustment mechanism 2 includes injection molding shell 201, which is the largest diameter injection molding shell for the bottle body and provides sliding guidance and support for the internal nested sliding shell 202. The outer wall of injection molding shell 201 is fixedly connected to the inner side of frame 1. The inner wall of injection molding shell 201 is slidably connected to the nested sliding shell 202, which is composed of multiple nested annular mold shells of different diameters. The required diameter can be quickly switched through the positioning hole 208 and the positioning block 207. The inner wall of the nested sliding shell 202 is slidably connected to the sliding column 203. The sliding column 203 moves back and forth to drive the nested sliding shell 202 to adjust its height and has a diameter locking function inside. The inside of the sliding column 203 is rotatably connected to the turntable 204. The front of the turntable 204... Guide grooves 205 are provided on both the left and right sides of the wall. The turntable 204 converts the rotational motion into the linear motion of the positioning block 207 through the guide grooves 205. Connecting pins 206 are slidably connected to the inner walls of the two guide grooves 205. Positioning blocks 207 are slidably connected to the left and right ends of the front side of the sliding column 203. The front ends of the two connecting pins 206 are fixedly connected to the rear side of the corresponding positioning block 207. Positioning holes 208 are provided on the left and right ends of the rear side of the inner wall of the nested sliding shell 202. The two positioning holes 208 are engaged with the corresponding positioning holes 208. A fixing plate 209 is fixedly connected to the rear side of the frame 1. A drive assembly 210 is provided on the rear side of the fixing plate 209. A sliding assembly 211 is provided at the bottom of the rear side of the fixing plate 209. The drive assembly 210 includes a movable plate 2101, which is connected to a servo motor 2102 and a sliding column 203 to transmit driving force. The front side of the movable plate 2101 is fixedly connected to the rear end of the sliding column 203, and the rear side of the movable plate 2101 is fixedly connected to the servo motor 2102. The servo motor 2102 precisely controls the rotation angle of the turntable 204, corresponding to the displacement accuracy of the positioning block 207. The output end of the servo motor 2102 passes through the rear side of the movable plate 2101 and the rear side of the sliding column 203 and is fixedly connected to the rear side of the turntable 204. The sliding assembly 211 includes two slide rails 2111. The front ends of the two slide rails 2111 are fixedly connected to the left and right ends of the rear bottom of the fixed plate 209, respectively. The top of each slide rail 2111 is slidably connected to a slider 2112. The top of each slider 2112 is fixedly connected to the left and right ends of the bottom of the movable block, respectively. The slide rails 2111 and sliders 2112 provide low-friction guidance for the movable plate 2101 to ensure straightness during height adjustment. The rear sides of the two slide rails 2111 are fixedly connected to the same connecting plate 2113. The rear side of the connecting plate 2113 is fixedly connected to a hydraulic cylinder 2114. The hydraulic cylinder 2114 drives the sliding column 203 to be quickly positioned. The output end of the hydraulic cylinder 2114 passes through the connecting plate 2113 and is fixedly connected to the rear bottom of the movable plate 2101. A folding rod 7 is fixedly connected to the top right front end of the frame 1. The folding rod 7 is used to adjust the viewing angle of the recognition camera 8. The top of the folding rod 7 is rotatably connected to the recognition camera 8. The recognition camera 8 automatically recognizes the shape and size of the bottle, which is convenient for intelligent adjustment. Specifically, when the bottle diameter needs to be adjusted, the servo motor 2102 is started to drive the turntable 204 to rotate. The turntable 204 guides the connecting pin 206 to slide along the guide groove 205, thereby pushing the positioning blocks 207 on both sides to move laterally in sync. The nested sliding shell 202 is made of mold shells of different diameters. By having the positioning blocks 207 engage with positioning holes 208 at different levels, the mold shell of the target diameter can be quickly selected. When adjusting the height, the hydraulic cylinder 2114 drives the moving plate 2101 to move backward along the slide rail 2111. The moving plate 2101 drives the sliding column 203 to move backward in sync. The sliding column 203 is locked with the mold shell of the selected diameter by the positioning block 207. During the backward movement, the inner nested sliding shell 202 smaller than the target diameter will move backward with the sliding column 203, thereby exposing the mold shell of the target diameter. The movement distance is determined by controlling the extension and retraction of the hydraulic cylinder 2114, thereby determining the bottle height. The shape and size of the bottle are automatically recognized by the recognition camera 8, which facilitates intelligent adjustment.

[0020] Reference Figure 1 , Figure 2 and Figure 6 The fixing mechanism 4 includes a second servo motor 401, which drives the gear 402 to rotate, thereby achieving precise control of the distance between the grippers 405. The bottom of the second servo motor 401 is fixedly connected to the top of the housing 3. The output end of the second servo motor 401 passes through the top of the housing 3 and is fixedly connected to the gear 402. The front and rear sides of the interior of the housing 3 are slidably connected to racks 403. The two racks 403 are respectively meshed with the front and rear sides of the gear 402. The opposite sides of the two racks 403 are fixedly connected to telescopic plates 404, which transmit clamping force. The front and rear ends of the two telescopic plates 404 pass through the inner wall of the housing 3. The front bottom of the two telescopic plates 404 is fixedly connected to grippers 405, which directly contact and clamp the bottle mouth mold 6. The rear bottom of the two telescopic plates 404 is provided with limit components 406. The limiting component 406 includes two limiting claws 4061. When the sliding column 203 drives the nested sliding shell 202 to retract, the limiting claws 4061 fix the mold shell layer that does not need to move, ensuring the accuracy of diameter adjustment. The tops of the two limiting claws 4061 are respectively fixedly connected to the bottoms of the corresponding telescopic plates 404. The top left and right sides of the frame 1 are provided with through grooves 4062. The through grooves 4062 provide a sliding path for the limiting claws 4061 and limit their range of movement. The outer walls of the two limiting claws 4061 are respectively slidably connected to the inner walls of the corresponding through grooves 4062. The positions of the two limiting claws 4061 are both set on the rear side of the injection mold shell 201. A groove 5 is provided on the inner bottom of the housing 3. The groove 5 provides guidance for the telescopic plate 404 to ensure the parallelism of the gripper 405 when it moves. The bottoms of the two telescopic plates 404 are slidably connected to the inner side of the groove 5. A bottle mouth mold 6 is provided on the front side of the frame 1, and the front end of the injection mold shell 201 passes through the frame 1. The position of the bottle mouth mold 6 corresponds to the position of the injection mold shell 201. Specifically, when changing the bottle mouth mold 6, the servo motor 401 starts, driving the gear 402 to rotate. The rotation of the gear 402 drives the two racks 403 to slide along the housing 3 in a direction away from each other. The racks 403 drive the telescopic plate 404 to move synchronously. The bottom of the telescopic plate 404 slides along the slide groove 5 to ensure smooth movement. The gripper 405 at the bottom moves along with it. By adjusting the spacing of the gripper 405, it can be adapted to bottle mouth molds 6 of different sizes, thereby quickly clamping and fixing the bottle mouth mold 6. At the same time, the limiting claw 4061 at the bottom of the telescopic plate 404 moves with the telescopic plate 404. When the adjustment mechanism 2 adjusts the diameter of the bottle body, the limiting claw 4061 can fix and limit the nested sliding shell 202 that does not need to move backward, preventing it from moving with the sliding column 203. After injection molding is completed, by stretching the telescopic plate 404, the telescopic plate 404 drives the bottle mouth mold 6 to move forward, so as to smoothly demold.

[0021] Working principle: When the bottle diameter needs to be adjusted, servo motor 2102 starts, driving turntable 204 to rotate. The guide groove 205 on turntable 204 rotates with it, forcing connecting pin 206 to slide along the groove, thereby pushing the positioning blocks 207 on both sides to move laterally synchronously. When the positioning block 207 is inserted into the positioning hole 208 of the nested sliding shell 202 of the corresponding diameter, the diameter is locked. The nested sliding shell 202 is composed of nested mold shells of different diameters, and the positioning blocks 207 are engaged with the positioning holes 208 of different levels. This means that the mold shell with the target diameter can be quickly selected. When adjusting the height, the hydraulic cylinder 2114 drives the moving plate 2101 to move backward along the slide rail 2111. The moving plate 2101 drives the sliding column 203 to move backward synchronously. Since the sliding column 203 is locked to the mold shell with the selected diameter through the positioning block 207, during the backward movement, the inner nested sliding shell 202 with a smaller diameter than the target diameter moves backward with the sliding column 203, exposing the mold shell with the target diameter. The movement distance is precisely controlled by the extension and retraction of the hydraulic cylinder 2114, thereby determining the height of the bottle. Furthermore, when changing the bottle mouth mold 6, the servo motor 401 starts and drives the gear 402 to rotate. Since the front and rear racks 403 mesh with the gear 402, the rotation of the gear 402 will drive the two racks 403 to slide along the housing 3 in a direction away from each other. The racks 403 drive the telescopic plate 404 to move synchronously. The bottom of the telescopic plate 404 slides along the slide groove 5 to ensure smooth movement. The gripper 405 at the bottom moves together. By adjusting the distance between the grippers 405, it can adapt to bottle mouth molds 6 of different sizes and achieve quick clamping and fixing. At the same time, the limiting claw 4061 at the bottom of the telescopic plate 404 moves with the telescopic plate 404. When the adjustment mechanism 2 adjusts the bottle diameter, for the nested sliding shell 202 that does not need to be moved backward, the limiting claw 4061 can fix and limit it to prevent it from moving with the sliding column 203. After injection molding is completed, by stretching the telescopic plate 404, the telescopic plate 404 drives the bottle mouth mold 6 to move forward, which facilitates smooth demolding.
