Description

Technical Field

[0001] This utility model relates to the field of medical device shell processing technology, specifically to a medical device shell mold that is easy to clean. Background Technology

[0002] Medical device housings are external structures used to protect, encapsulate, and support the internal components of medical devices. Molds are required for the processing and molding of medical device housings.

[0003] The utility model patent application with publication number "CN221756654U" discloses a mold for producing medical device shells that facilitates ejection. It mainly consists of a base, supporting legs, ejection mechanism, forming component, mounting plate, bearing plate and hydraulic rod. This technical solution can effectively eject the workpiece formed inside the forming component slowly, forming a rapid demolding effect. Moreover, because the top plate is a single piece, the formed workpiece is subjected to uniform force during the ejection process and will not undergo shape changes, thereby improving the overall work efficiency and equipment stability.

[0004] The molds for producing medical device housings disclosed in the aforementioned documents have the following defects: after the molded workpiece is ejected, some of the workpiece debris can easily remain in the cavity of the lower mold, which in turn affects the quality of the subsequent molding of the medical device housing. In the prior art, manual cleaning of the debris in the lower mold is generally used, which is laborious and poses certain safety hazards.

[0005] Therefore, it can be seen that the molds used for producing medical device shells in the existing technology do not have a good cleaning structure. Utility Model Content

[0006] The purpose of this invention is to provide an easy-to-clean mold for medical device housings, solving the problem that existing molds used in the production of medical device housings are not easy to clean.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an easy-to-clean medical device shell mold, comprising a base plate, a lower mold and a guide rod mounted on the upper surface of the base plate, a top plate mounted on the upper surface of the guide rod, a hydraulic cylinder mounted on the upper surface of the top plate, the output end of the hydraulic cylinder penetrating the top plate and mounted on a movable plate, the movable plate being slidably connected to the outer surface of the guide rod, an upper mold mounted on the lower surface of the movable plate, a cleaning structure provided at one end of the base plate, the cleaning structure comprising a movable component and a cleaning component, the cleaning component comprising a frame, a reciprocating screw rotatably connected to the inner surface of the frame, a movable block threadedly connected to the outer surface of the reciprocating screw, an installation groove provided on the lower surface of the movable block, a connecting block provided inside the installation groove, a plurality of cleaning brushes provided on the lower surface of the connecting block, a limit rod also provided on the inner surface of the frame, a movable block slidably connected to the outer surface of the limit rod, a first support frame mounted on the outer surface of the frame, a first drive motor mounted at one end of the first support frame, and a reciprocating screw mounted on the first drive motor via a coupling.

[0009] Furthermore, a second support frame is installed on the outer surface of the movable block. The outer surface of the second support frame has a mounting hole. One end of the mounting hole passes through the movable block and extends into the interior of the connecting block. A slide rod is slidably connected inside the mounting hole. A pull block is installed at one end of the slide rod. A baffle is installed on the outer surface of the slide rod. A spring is sleeved on the outer surface of the slide rod. One end of the spring is installed on the outer surface of the baffle, and the other end of the spring is installed on the outer surface of the second support frame.

[0010] Furthermore, the movable component includes a connecting frame, which is mounted on the outer surface of the base plate. The outer surface of the connecting frame has an opening, and a rack is slidably connected inside the opening. A frame is mounted on one end of the rack, and a limit plate is mounted on the other end of the rack.

[0011] Furthermore, the outer surface of the connecting frame is provided with two side plates, and a rotating shaft is rotatably connected between the two side plates. A gear is installed on the outer surface of the rotating shaft, and the gear meshes with a rack. A second drive motor is installed on the outer surface of one of the side plates, and the output end of the second drive motor is connected to the rotating shaft through a coupling.

[0012] Furthermore, an auxiliary groove is provided on the inner surface of the connecting frame, and an auxiliary slider is slidably connected inside the auxiliary groove. The auxiliary slider is mounted on the upper surface of the rack.

[0013] Furthermore, the lower surface of the upper mold is provided with a limiting block, and the upper surface of the lower mold is provided with a limiting groove, and the limiting block is fitted inside the limiting groove.

[0014] This utility model has the following beneficial effects:

[0015] (1) By starting the first drive motor, the output end of the first drive motor drives the reciprocating screw to rotate through the rotating shaft. The rotation of the reciprocating screw causes the moving block connected to it to reciprocate linearly along the direction of the limiting rod. When the moving block moves, the cleaning brush will brush the forming cavity of the lower mold to remove residues, thus achieving a better cleaning effect.

[0016] (2) By pulling the pull block outward, the pull block causes the slide rod to move outward in the mounting hole. The spring gradually contracts, and at the same time, one end of the slide rod gradually disengages from the mounting hole of the moving block. When one end of the slide rod completely disengages from the mounting hole of the moving block, the cleaning brush can be pulled down to disengage the connecting block from the inside of the mounting groove, thereby achieving the effect of quick disassembly of the moving block and the connecting block.

[0017] 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

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-5 As shown, this utility model is an easy-to-clean medical device shell mold, including a base plate 1. A lower mold 2 and a guide rod 3 are installed on the upper surface of the base plate 1. A top plate 4 is installed on the upper surface of the guide rod 3. A hydraulic cylinder 5 is installed on the upper surface of the top plate 4. The output end of the hydraulic cylinder 5 passes through the top plate 4 and is equipped with a movable plate 6. The movable plate 6 is slidably connected to the outer surface of the guide rod 3. An upper mold 7 is installed on the lower surface of the movable plate 6. A cleaning structure is provided at one end of the base plate 1. The cleaning structure includes a movable component 802 and a cleaning component 801. The cleaning component 801 includes a frame 80101. A reciprocating screw 80102 is rotatably connected to the inner surface of the frame 80101. The outer surface of 80102 is threaded with a movable block 80103. The lower surface of the movable block 80103 is provided with an installation groove. The interior of the installation groove is provided with a connecting block 80104. The lower surface of the connecting block 80104 is provided with several cleaning brushes 80105. The inner surface of the frame 80101 is also provided with a limit rod 80106. The outer surface of the limit rod 80106 is slidably connected with the movable block 80103. The outer surface of the frame 80101 is mounted with a first support frame 80107. One end of the first support frame 80107 is mounted with a first drive motor 80108. The first drive motor 80108 is mounted with a reciprocating screw 80102 through a coupling.

[0028] The movable component 802 includes a connecting frame 80201, which is mounted on the outer surface of the base plate 1. An opening is provided on the outer surface of the connecting frame 80201, and a rack 80202 is slidably connected inside the opening. A frame 80101 is installed at one end of the rack 80202, and a limit plate 80203 is installed at the other end of the rack 80202.

[0029] The outer surface of the connecting frame 80201 is provided with two side plates 80204, and a rotating shaft 80205 is rotatably connected between the two side plates 80204. A gear 80206 is installed on the outer surface of the rotating shaft 80205, and the gear 80206 meshes with the rack 80202. A second drive motor 80207 is installed on the outer surface of one of the side plates 80204, and the output end of the second drive motor 80207 is connected to the rotating shaft 80205 through a coupling.

[0030] In use, the workpiece is placed in the forming cavity of the lower mold 2. The hydraulic cylinder 5 is activated, causing the output end of the hydraulic cylinder 5 to push the moving plate 6 downward, so that the upper mold 7 and the lower mold 2 are closed and the workpiece is processed. After the workpiece is processed, the hydraulic cylinder 5 is operated, so that the hydraulic cylinder 5 drives the moving plate 6 upward and separates the upper mold 7 from the lower mold 2. Then the processed workpiece is taken out, and the processing of the workpiece is completed.

[0031] After the workpiece is processed, the second drive motor 80207 is started, causing the output of the second drive motor 80207 to drive the rotating shaft 80205 to rotate. When the rotating shaft 80205 rotates, it drives the gear 80206 to rotate. Since the gear 80206 meshes with the rack 80202, the rotation of the gear 80206 drives the rack 80202 to move and push the frame 80101 to move. When the frame 80101 is directly above the lower mold 2, the second drive motor 80207 is turned off. The drive motor 80207 starts the first drive motor 80108, causing the output end of the first drive motor 80108 to drive the reciprocating screw 80102 to rotate through the rotating shaft 80205. The rotation of the reciprocating screw 80102 causes the moving block 80103 threadedly connected to it to reciprocate linearly along the direction of the limit rod 80106. When the moving block 80103 moves, the cleaning brush 80105 will brush the molding cavity of the lower mold 2 to remove residues.

[0032] After the lower mold 2 is cleaned, the first drive motor 80108 is turned off and the second drive motor 80207 is turned on, so that the output end of the second drive motor 80207 rotates in the opposite direction, driving the frame 80101 to reset.

[0033] A second support frame 9 is mounted on the outer surface of the movable block 80103. The outer surface of the second support frame 9 has a mounting hole. One end of the mounting hole passes through the movable block 80103 and extends into the interior of the connecting block 80104. A slide rod 10 is slidably connected inside the mounting hole. A pull block 11 is mounted on one end of the slide rod 10. A baffle 12 is mounted on the outer surface of the slide rod 10. A spring 13 is sleeved on the outer surface of the slide rod 10. One end of the spring 13 is mounted on the outer surface of the baffle 12, and the other end of the spring 13 is mounted on the outer surface of the second support frame 9.

[0034] When the connecting block 80104 needs to be disassembled, by pulling the pull block 11 outward, the pull block 11 causes the slide rod 10 to move outward in the mounting hole, the spring 13 gradually contracts, and at the same time, one end of the slide rod 10 gradually disengages from the mounting hole opened in the moving block 80103. When one end of the slide rod 10 is completely disengaged from the mounting hole opened in the moving block 80103, the cleaning brush 80105 can be pulled down to disengage the connecting block 80104 from the inside of the mounting groove, thereby realizing the quick disassembly of the moving block 80103 and the connecting block 80104.

[0035] An auxiliary groove is provided on the inner surface of the connecting bracket 80201, and an auxiliary slider 80208 is slidably connected inside the auxiliary groove. The auxiliary slider 80208 is installed on the upper surface of the rack 80202.

[0036] The auxiliary slider 80208 slides in the auxiliary groove of the connecting frame 80201, which can increase the stability of the rack 80202 and the frame 80101 when they move.

[0037] The lower surface of the upper mold 7 is provided with a limiting block 701, and the upper surface of the lower mold 2 is provided with a limiting groove. The limiting block 701 is installed inside the limiting groove.

[0038] By using the limit block 701 in conjunction with the limit groove, the positions of the upper mold 7 and the lower mold 2 can be positioned to prevent positional displacement when the upper mold 7 and the lower mold 2 are closed.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
