Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically a medical blister box injection molding mold. Background Technology

[0002] Medical blister packs are packaging boxes specifically designed for storing and transporting medical supplies. The choice of material for medical blister packs is crucial. Commonly used materials include PETG, APET, PS, and PP, which have good sealing and moisture-proof properties, ensuring the safety of medical supplies during storage and use. Generally, medical blister packs are made of these materials.

[0003] Patent CN213675428U discloses a plastic box forming mold for a vacuum forming machine, including a base plate. Columns are fixedly connected to the upper left and right surfaces of the base plate. A top plate is fixedly connected to the upper surface of the columns. An upper pressure block assembly is fixedly connected to the lower end of the top plate. The left and right sides of the upper pressure block assembly are slidably connected to the columns. A mold platform is fixedly connected to the upper middle surface of the base plate, and a partition is fixedly connected inside the mold platform. Through the combined action of the vertical top mold component and the horizontal push rod, the push rod slides inside the groove under manual force, quickly lifting the top mold component and separating the plastic box product from the mold.

[0004] The above-mentioned device has certain shortcomings when in use: since most injection molding processes involve injecting hot melt plastic into the mold for molding, after molding, the upper and lower molds separate. Because the surface of the mold is still at a high temperature after molding, it needs to be cooled before it can be removed. The cooling time is the processing window, which reduces the overall processing efficiency.

[0005] To address these issues, this invention provides a medical blister box injection molding die. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a medical blister box injection molding mold, which solves the above-mentioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a medical blister box injection molding mold, including a workbench, a U-shaped frame fixedly installed on the top wall of the workbench, a mold closing assembly installed on the top wall of the U-shaped frame, a cooling assembly fixedly installed on the top wall of the U-shaped frame, the cooling assembly being fixedly connected to the rear wall of the mold closing assembly, and a circulation assembly installed on the top wall of the workbench;

[0008] The mold-closing assembly includes two hydraulic rods, which are fixedly installed on the top wall of the U-shaped frame. The movable ends of the two hydraulic rods slide through the U-shaped frame and are fixedly installed with a lifting plate. Several upper molds are evenly fixedly installed on the bottom wall of the lifting plate. Limiting grooves are opened on the inner side wall of the U-shaped frame.

Lower molds are installed on the inner wall of the circulation assembly at the positions corresponding to the upper molds.

[0009] The cooling assembly includes a fan dryer, which is fixedly installed at the center of the top wall of the U-shaped frame. The air outlet of the fan dryer is connected to an air outlet pipe, and the bottom end of the air outlet pipe is connected to a flexible hose. The bottom end of the flexible hose is connected to a connecting pipe. A connecting pipe is fixedly installed on the rear wall of the lifting plate through several mounting seats. Several L-shaped pipes are evenly connected to the outer wall of the connecting pipe, and several air outlet covers are connected to the front of the outer wall of each of the L-shaped pipes.

[0010] The above technical solution enables rapid cooling of the molded blister box, shortens the waiting time during the processing window, and provides excellent working performance during use.

[0011] Furthermore, the two hydraulic rods are arranged symmetrically on the left and right, the rear wall of the lifting plate is fixedly connected to the cooling assembly, the outer wall of the lifting plate is slidably connected to the inner wall of the U-shaped frame, and the outer walls of the two limiting sliders are slidably connected to the inner walls of the corresponding limiting grooves.

[0012] Through the above technical solution, the limiting slider mainly limits the movement trajectory of the lifting plate to prevent positional deviation and mold misalignment.

[0013] Furthermore, the air inlet of the dryer is connected to the outside, the bottom end of the connecting pipe is connected to the connecting pipe, the position of the L-shaped pipe and the air outlet hood are matched with the position of the corresponding upper mold, and the top wall of the workbench is provided with through slots corresponding to the positions of the L-shaped pipe and the air outlet hood.

[0014] The through-slot, as described above, is primarily designed to accommodate the L-shaped pipe and the air outlet hood.

[0015] Furthermore, the circulation component includes a receiving frame, the top wall of the workbench has a receiving cavity, the outer wall of the receiving frame is fitted with the inner wall of the receiving cavity, and the inner wall of the receiving frame is fixedly connected to the bottom walls of several lower molds.

[0016] The above technical solution enables the receiving frame to be mainly used for installing the lower mold.

[0017] Furthermore, a positioning plate is fixedly installed on the top wall of the receiving frame, and a positioning groove is provided on the top wall of the workbench at the position corresponding to the positioning plate, with the inner wall of the positioning groove fitting against the outer wall of the positioning plate.

[0018] Through the above technical solution, the positioning plate and positioning groove cooperate with each other to make the lower mold and the upper mold positions match.

[0019] Furthermore, the inner wall of the receiving cavity is provided with an installation groove, and a heat dissipation water cooling pipe is fixedly installed on the inner wall of the installation groove. The top right side of the heat dissipation water cooling pipe is connected to a water inlet pipe, and the bottom right side of the heat dissipation water cooling pipe is connected to a water outlet pipe.

[0020] Through the above technical solution, the heat dissipation water cooling pipeline can drive the temperature inside the lower mold and improve the molding speed.

[0021] Furthermore, a control assembly is installed on the left side of the front wall of the workbench.

[0022] Through the above technical solution, the control assembly is mainly used to control the electrical control equipment of the entire device.

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] Please see Figure 1-4 A medical blister box injection molding mold includes a workbench 1, a U-shaped frame 3 fixedly installed on the top wall of the workbench 1, a mold closing assembly 4 installed on the top wall of the U-shaped frame 3, a cooling assembly 6 fixedly installed on the top wall of the U-shaped frame 3, the cooling assembly 6 being fixedly connected to the rear wall of the mold closing assembly 4, and a circulation assembly 5 installed on the top wall of the workbench 1.

[0035] The mold clamping assembly 4 includes two hydraulic rods 41, which are fixedly installed on the top wall of the U-shaped frame 3. The movable ends of the two hydraulic rods 41 slide through the U-shaped frame 3 and are fixedly installed with a lifting plate 42. Several upper molds 43 are evenly fixedly installed on the bottom wall of the lifting plate 42. Limiting grooves 44 are opened on the inner side wall of the U-shaped frame 3. Limiting sliders 45 are fixedly installed on the outer side wall of the lifting plate 42 at the position corresponding to the limiting grooves 44. Lower molds 46 are installed on the inner wall of the circulation assembly 5 at the position corresponding to the upper molds 43. The two hydraulic rods 41 are arranged symmetrically on the left and right. The rear wall of the lifting plate 42 is fixedly connected to the cooling assembly 6. The outer side wall of the lifting plate 42 is slidably connected to the inner side wall of the U-shaped frame 3. The outer walls of the two limiting sliders 45 are slidably connected to the inner walls of the corresponding limiting grooves 44.

[0036] The cooling assembly 6 includes a dryer 61, which is fixedly installed at the center of the top wall of the U-shaped frame 3. The air outlet of the dryer 61 is connected to an air outlet pipe 62, and the bottom end of the air outlet pipe 62 is connected to a flexible hose 68. The bottom end of the flexible hose 68 is connected to a connecting pipe 63. The rear wall of the lifting plate 42 is fixedly installed with a connecting pipe 64 through several mounting seats. Several L-shaped pipes 65 are evenly connected to the outer wall of the connecting pipe 64. Several air outlet hoods 66 are connected to the front of the outer wall of the L-shaped pipes 65. The air inlet of the dryer 61 is connected to the outside. The bottom end of the connecting pipe 63 is connected to the connecting pipe 64. The positions of the L-shaped pipes 65 and the air outlet hoods 66 are matched with the corresponding positions of the upper mold 43. Through slots 67 are opened on the top wall of the workbench 1 at the positions of the L-shaped pipes 65 and the air outlet hoods 66.

[0037] In this embodiment of the utility model, the purpose of this arrangement is that the upper mold 43 and the lower mold 46 can be matched by the mold closing component 4. When the upper mold 43 moves up and down, its movement path is limited by the lifting plate 42 and the limiting slide 44 to prevent it from deviating from its movement path. Furthermore, the cooling component 6 can quickly cool the molded blister box after the upper mold 43 and the lower mold 46 are demolded, making it convenient for workers to pick up the finished products, shortening the waiting time, and improving the overall processing efficiency.

[0038] Example 2:

[0039] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: the circulation component 5 includes a receiving frame 51, a receiving cavity 58 is opened on the top wall of the workbench 1, the outer wall of the receiving frame 51 is attached to the inner wall of the receiving cavity 58, the inner wall of the receiving frame 51 is fixedly connected to the bottom wall of several lower molds 46, a positioning plate 52 is fixedly installed on the top wall of the receiving frame 51, a positioning groove 53 is opened on the top wall of the workbench 1 at the position corresponding to the positioning plate 52, the inner wall of the positioning groove 53 is attached to the outer wall of the positioning plate 52, an installation groove 54 is opened on the inner wall of the receiving cavity 58, a heat dissipation water cooling pipe 55 is fixedly installed on the inner wall of the installation groove 54, a water inlet pipe 56 is connected to the top right side of the heat dissipation water cooling pipe 55, a water outlet pipe 57 is connected to the bottom right side of the heat dissipation water cooling pipe 55, and a control assembly 2 is installed on the left side of the front wall of the workbench 1;

[0040] In this embodiment of the utility model, the purpose of this arrangement is to ensure that the lower mold 46 and the upper mold 43 are matched in position through the cooperation of the receiving frame 51, the positioning plate 52 and the positioning groove 53, so as to prevent the offset. Furthermore, through the cooperation of the external water cooling equipment, the heat dissipation water cooling pipe 55, the water outlet pipe 57 and the water inlet pipe 56, the receiving frame 51 and the lower mold 46 are cooled by circulating water, thereby improving the molding speed of the mold and thus speeding up the workflow of the entire device.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, the hydraulic rod 41 and the air dryer 61 are first electrically connected via an external power supply and control assembly 2. The outlet of the external water-cooling equipment is connected to the inlet pipe 56, and the inlet is connected to the outlet pipe 57. The lower mold 46 and the receiving frame 51 are integrally formed. The lower mold 46 is placed into the receiving cavity 58 by the movable positioning plate 52, so that the positioning plate 52 fits against the inner wall of the positioning groove 53. The hydraulic rod 41 pushes the lifting plate 42 down, causing the corresponding limit slider 45 to slide downward in the inner wall of the limit groove 44. At the same time, the lifting plate 42 causes the upper mold 43 and the corresponding lower mold 46 to close and form the mold. When the lifting plate 42 moves, it will drive the connecting pipe 64, the connecting pipe 63, and the movable hose 68 to move. The connecting pipe 64 simultaneously drives the L-shaped pipe 65 and the air hood 66 into the inner wall of the through groove 67. Through the high-pressure injection pipe installed on the front wall of the upper mold 43, the mold is filled with high pressure. The inner wall of the mold 46 is filled with hot melt injection molding material. After injection molding is completed, coolant is delivered into the inlet pipe 56 through an external water cooling device. The coolant circulates in the heat dissipation water cooling pipe 55 to remove the heat inside the lower mold 46 and is discharged from the outlet pipe 57. When the processing time is reached, the movable end of the hydraulic rod 41 retracts, causing the lifting plate 42 to rise. The limit slider 45 slides downward in the inner wall of the limit slide groove 44. The lifting plate 42 causes the upper mold 43 to be demolded from the corresponding lower mold 46. When the lifting plate 42 is moving, it will drive the connecting pipe 64, the connecting pipe 63, and the movable hose 68 to move. The connecting pipe 64 simultaneously drives the L-shaped pipe 65 and the air hood 66 to detach from the inner wall of the through groove 67. Then, the air dryer 61 is started to send air into the air duct 62. The air is then blown out through the movable hose 68, the connecting pipe 63, the connecting pipe 64, the L-shaped pipe 65, and the air hood 66 to cool the molded blister box and shorten the cooling time during the processing window.
