Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an irregularly shaped medicine packaging embedded positioning and pressing mold. Background Technology

[0002] The pressing mold is the key equipment for manufacturing such irregularly shaped explosive packages. It is made of high-strength alloy material and uses hydraulic or mechanical pressure to press the explosive raw materials into a specific shape. The precision machining of the mold cavity ensures the dimensional accuracy and density uniformity of the explosive.

[0003] Currently, most existing medicine packaging molds use fixed supports. For medicines with size deviations or irregular shapes, workers need to manually adjust the position. Otherwise, the press head is easily subjected to bias pressure, causing the medicine package to fall off. It is impossible to automatically and accurately position irregularly shaped medicine packages during the pressing process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that require manual adjustment of the position when dealing with medicines with dimensional deviations or irregular shapes, and to propose an embedded positioning and pressing mold for irregularly shaped medicines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An irregularly shaped, packaged, embedded positioning and pressing mold for medicines includes:

[0007] The frame has four support columns fixedly installed on its top in a rectangular shape. The top of the four support columns is fixedly installed with the same fixed frame. The lower mold is fixedly installed on the top of the frame.

[0008] The lower mold is equipped with a positioning and clamping mechanism, which is used to force the irregularly shaped medicine package toward the center of the mold.

[0009] In one possible design, the positioning and clamping mechanism includes a support rod fixedly disposed inside the lower mold, a slide rail slidably disposed on the outside of the support rod, a placement groove opened on the top of the lower mold, four cavities opened around the placement groove of the lower mold, and a gripper placed in each of the four cavities, the bottom ends of the four grippers being hinged to the four outer corners of the slide rail, and a linkage rod hinged to the middle section of each of the four grippers, with the adjacent ends of the four linkage rods being hinged to the outer top of the support rod.

[0010] In one possible design, connecting rods are fixedly installed at the other four corners of the outer side of the slide, and pressure rods are fixedly installed at the outer ends of the four connecting rods. The four connecting rods are longitudinally slidably installed in the lower mold, and the four pressure rods are longitudinally slidably installed through the lower mold. A strong spring is installed at the bottom of the slide outside the support rod. The top end of the strong spring abuts against the bottom of the slide, and the bottom end of the strong spring abuts against the bottom wall of the lower mold.

[0011] In one possible design, a top plate is embedded in the top of the lower mold at the center of the placement groove. The bottom of the top plate is rectangularly fixed with four push rods. The four push rods are slidably disposed inside the lower mold, and the bottom ends of the four push rods are fixedly connected to the tops of four connecting rods.

[0012] In one possible design, rubber pads are fixedly provided on the inner sides of all four grippers, and striped grooves are fixedly provided on the upper inner sides of all four rubber pads.

[0013] In one possible design, the four support columns are slidably mounted on the same movable frame. The bottom of the movable frame is fixedly mounted on the upper mold directly above the lower mold. A hydraulic cylinder is fixedly mounted on the top of the fixed frame, and the output end of the hydraulic cylinder is fixedly connected to the top of the movable frame.

[0014] In one possible design, the bottom of the frame is rectangularly fixed with four casters. Threaded sleeves are fixedly installed next to each of the four casters at the bottom of the frame. Each of the four threaded sleeves has a screw threaded to its bottom end. Each of the four screws has an adjusting block fixedly installed at its bottom end. Each of the four adjusting blocks has a support pad rotatably installed at its bottom.

[0015] In this application, upon initial use, the four rectangular casters fixed at the bottom of the frame are used to smoothly move the entire device to the designated position. Once in position, the operator begins the fixing process by rotating the adjusting block located next to the four casters. Because the adjusting block is fixedly connected to the screw, and the screw is threadedly connected to the threaded sleeve, the screw will rotate out from inside the threaded sleeve and gradually extend during the rotation of the adjusting block. Continue rotating the adjusting block until the support pad at the bottom of the screw is firmly against the ground. At this point, rotate the locking nut connected to the external thread of the screw to make it firmly against the bottom of the threaded sleeve. This completes the fixing and support of the frame position, ensuring that the equipment remains stable during subsequent operation and that the pressing accuracy is not affected by shaking.

[0016] The irregularly shaped medicine package is then placed in the placement slot of the lower mold. At this time, the medicine package will be located on the top platen. Since it has not yet been subjected to external force, the top platen is in a high position. Next, the hydraulic cylinder fixedly mounted on the top of the fixed frame is activated. The output end of the hydraulic cylinder starts working, pushing the movable frame fixedly connected to it to slide downwards along the four support columns. During the downward movement of the movable frame, it will also drive the upper mold fixedly mounted directly above the lower mold to move downwards together. When the upper mold gradually moves down and contacts the four pressure rods, it will exert downward pressure on the pressure rods, pushing the pressure rods downwards. The downward movement of the pressure rods will also drive the connecting rod fixedly connected to them to move downwards together. The connecting rod is fixedly connected to the slide. The slide will also move downward outside the support rod. During the downward movement of the slide, it will compress the strong spring located between its bottom and the bottom wall of the lower mold, so that the strong spring will store force. At the same time as the slide moves down, since its four outer corners are hinged to the bottom of the four grippers, it will pull the four corners of the four grippers, so that the four grippers will close synchronously towards the center in the cavity opened around the placement slot. During the process of closing towards the center, the four grippers physically form a gradually shrinking cavity. This cavity is like a guide, forcibly pushing the irregularly shaped medicine bag to the center position of the lower mold, realizing the operation process of centering first and then pressurizing, ensuring the absolute accuracy of the embedded position of the irregularly shaped medicine bag;

[0017] As the pressure rod and connecting rod move down, the top of the four push rods is fixedly connected to the bottom of the top plate and the bottom is fixedly connected to the top of the four connecting rods. Therefore, the push rods will drive the top plate to move down until its top surface is flush with the placement groove. During this process, the irregularly shaped medicine bag will be pushed into the placement groove at the center of the lower mold at the same time.

[0018] As the upper mold continues to move downwards, when it fully contacts the lower mold, the final pressing operation on the irregularly shaped medicine package is completed. At this point, the rubber pads fixed on the inner sides of the four grippers will be in close contact with the irregularly shaped medicine package. The striped grooves fixed on the inner side of the rubber pads at the top can increase the friction between the rubber pads and the irregularly shaped medicine package, preventing the irregularly shaped medicine package from sliding during the pressing process, further ensuring the precision and quality of the pressing. After pressing is completed, the output end of the hydraulic cylinder retracts, driving the upper mold to move upwards. At the same time, the powerful spring releases its stored force, pushing the slide to move upwards. The upward movement of the slide will cause the grippers to open, and the top plate will also move upwards under the action of the push rod, pushing the pressed irregularly shaped medicine package out of the placement slot for easy removal by the operator. Thus, the entire irregularly shaped medicine package embedding and positioning pressing process is completed.

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

[0020] This invention, through the setting of a positioning and clamping mechanism, can force the irregularly shaped medicine package to the center of the lower mold, achieving centering first and then pressure, solving the problem of the difficulty in accurately placing irregularly shaped medicine packages due to their irregular shape, effectively avoiding pressing defects caused by placement deviation, ensuring the absolute accuracy of the embedded position of the irregularly shaped medicine package, thereby significantly improving the quality stability and consistency of the pressed product, reducing the scrap rate, and improving production efficiency and economic benefits.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In one embodiment

[0028] Reference Figure 1-4 A pressing mold, comprising:

[0029] The machine includes a frame 1, support columns 2, a fixed frame 3, a movable frame 4, an upper mold 5, a hydraulic cylinder 6, a lower mold 7, and a positioning and clamping mechanism. The frame 1 serves as the basic support structure for the entire mold. The top of the frame 1 is rectangularly fixedly equipped with four support columns 2. The tops of these four support columns 2 are all fixedly connected to the same fixed frame 3, providing stable support for the movement of the upper mold 5. The same movable frame 4 is slidably mounted on the outside of the four support columns 2. The bottom of the movable frame 4 is located directly above the lower mold 7 and the upper mold 5 is fixedly installed thereon. The top of the fixed frame 3 is fixedly installed with a hydraulic cylinder 6. The output end of the hydraulic cylinder 6 is fixedly connected to the top of the movable frame 4. When it is necessary to press irregularly shaped medicine bags, the hydraulic cylinder 6 is activated, and its output end pushes the movable frame 4 to slide downward along the four support columns 2, thereby driving the upper mold 5 to move downward, realizing the pressing operation of irregularly shaped medicine bags.

[0030] The lower mold 7 is fixedly mounted on the top of the frame 1. A positioning and clamping mechanism is provided on it to force irregularly shaped medicine packets towards the center of the mold. This positioning and clamping mechanism includes a support rod 8 fixedly mounted inside the lower mold 7, and a slide 9 slidably mounted on the outside of the support rod 8. A placement groove 701 is provided on the top of the lower mold 7 for placing irregularly shaped medicine packets. Four cavities are provided around the placement groove 701 on the lower mold 7. Each cavity contains a gripper 10. The bottom ends of the four grippers 10 are hinged to the four outer corners of the slide 9. A linkage rod 11 is hinged to the middle section of each of the four grippers 10. Connecting rods 13 are fixedly mounted on the other four outer corners of the slide 9. Pressure rods 14 are fixedly mounted on the outer ends of each of the four connecting rods 13. The four connecting rods 13 are slidably mounted longitudinally within the lower mold 7, and the four pressure rods 14 are slidably mounted longitudinally through the lower mold 7. The slide 9... A powerful spring 12 is installed at the bottom outside the support rod 8. The top of the powerful spring 12 abuts against the bottom of the slide 9, and the bottom of the powerful spring 12 abuts against the bottom wall of the lower mold 7. The ends of the four linkage rods 11 that are close to each other are hinged to the outer top of the support rod 8. When the upper mold 5 gradually moves down and contacts the four pressure rods 14, it will apply downward pressure to the pressure rods 14, pushing the pressure rods 14, connecting rods 13 and slide 9 to move down along the support rod 8. During the downward movement of the slide 9, the powerful spring 12 will be compressed to store force. At the same time, since the bottom of the four grippers 10 is hinged to the four corners of the outer side of the slide 9, and the middle section is hinged to the outer top of the support rod 8 through the linkage rods 11, the downward movement of the slide 9 will pull the four grippers 10 to close synchronously towards the center in the cavity, forming a gradually shrinking cavity, forcibly pushing the irregularly shaped medicine pack to the center position of the lower mold 7, achieving precise centering.

[0031] The lower mold 7 is located at the top of the placement groove 701, where a top plate 15 is embedded. The bottom of the top plate 15 is rectangularly fixed with four push rods 16. The four push rods 16 are slidably disposed inside the lower mold 7. The bottom ends of the four push rods 16 are fixedly connected to the tops of the four connecting rods 13. When the pressure rod 14 and the connecting rods 13 move down, the push rods 16 drive the top plate 15 to move down until its top surface is flush with the placement groove 701, further pushing the irregularly shaped medicine pack into the placement groove 701 at the center of the lower mold 7.

[0032] Rubber pads 17 are fixedly provided on the inner side of each of the four grippers 10. The rubber pads 17 can increase the friction between the gripper and the irregularly shaped medicine bag and prevent the medicine bag from sliding during the pressing process. The inner side of each of the four rubber pads 17 is fixedly provided with striped grooves 18 on the upper side. The striped grooves 18 further increase the friction and further ensure the precision and quality of the pressing.

[0033] This application can be used in the field of embedded positioning and pressing molds for irregularly shaped open packaging drugs, and can also be used in other fields applicable to this application.

[0034] In another embodiment, refer to Figure 2 An embedded positioning and pressing mold for irregularly shaped open-packed medicine is disclosed. This embodiment is applied to the field of embedded positioning and pressing mold technology for irregularly shaped open-packed medicine. The structure of this embodiment is basically the same as that of the previous embodiment, except that: four movable wheels 19 are fixedly installed in a rectangular shape at the bottom of the frame 1 to facilitate the movement of the mold between different workstations. When the mold is moved to the designated position, the frame 1 needs to be fixed. At this time, the operator rotates the adjusting block located next to the four movable wheels 19. Since the adjusting block is fixedly connected to the screw 21 and the screw 21 is threadedly connected to the threaded sleeve 20, rotating the adjusting block will cause the screw 21 to turn out from the inside of the threaded sleeve 20 and gradually extend until the support pad 22 at the bottom of the screw 21 is in close contact with the ground. Then, the locking nut connected to the external thread of the screw 21 is tightened so that it is tightly pressed against the bottom of the threaded sleeve 20, thus completing the fixing of the frame 1 and ensuring that the mold remains stable during the subsequent pressing process and will not affect the pressing accuracy due to shaking.

[0035] However, as is well known to those skilled in the art, the working principle and wiring method of hydraulic cylinder 6 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
