Description

Technical Field

[0001] This application relates to the field of injection molding of rehabilitation instrument housings, and in particular to injection molds for rehabilitation instrument housings. Background Technology

[0002] Medical aesthetic and rehabilitation instruments are medical devices mainly used for treatment, health care, prevention, and rehabilitation.

[0003] In the production and assembly of existing medical aesthetic rehabilitation instruments, internal electronic components are usually installed inside the instrument housing. The existing rehabilitation instrument housing is usually a one-piece design, which requires injection molding. Furthermore, the shapes of rehabilitation instrument housings vary, making it difficult for existing injection molds to quickly produce rehabilitation instrument housings of different shapes. Therefore, existing injection molds are inconvenient to use. Utility Model Content

[0004] To further improve the rapid injection molding production of rehabilitation instrument shells with different shapes, this application provides an injection mold for rehabilitation instrument shells.

[0005] The injection mold for the rehabilitation device housing provided in this application adopts the following technical solution: The injection mold for the rehabilitation device housing includes a base and an upper mold connected to an external driving device. A lower mold is fixedly installed on the top of the base. An injection port is provided on the top of the upper mold. A lower mold opening is provided on the lower mold. A first mold core is provided inside the lower mold opening. An upper mold opening is provided at the bottom of the upper mold. A second mold core is provided inside the upper mold opening. A disassembly and assembly mechanism is provided on the upper mold.

[0006] The disassembly and assembly mechanism includes two rectangular slots symmetrically opened in the upper mold opening. A corresponding rectangular block is slidably installed in each of the two rectangular slots. Both rectangular blocks are fixedly installed with the second mold core. Two corresponding threaded rods are slidably installed through one side of the upper mold. The two threaded rods pass through the corresponding rectangular blocks. A corresponding nut is screwed onto the exposed surface of the two threaded rods. The first mold core and the second mold core are both provided with corresponding demolding layers.

[0007] By adopting the above technical solution, the second mold core can be removed by disassembling the threaded rod, and mold cores of different shapes can be disassembled and replaced. Therefore, it is convenient to quickly produce injection molded housings of different shapes, improving the convenience and flexibility of use.

[0008] Preferably, one end of each of the two threaded rods is fixedly mounted with the same connecting plate, and a pull rod is fixedly mounted on one side of the connecting plate.

[0009] By adopting the above technical solution, the connecting plate can be moved by setting a tie rod.

[0010] Preferably, the two bases are fixedly installed with the same support plate on their adjacent sides, and two electric telescopic rods are symmetrically fixedly installed on the top of the support plate. The output ends of the two electric telescopic rods pass through the bottom of the first mold core and are fixedly installed with a top plate. The top plate is the same size and shape as the first mold core.

[0011] By adopting the above technical solution, the output end of the electric telescopic rod will push the top plate downward, and the top plate will move upward, which will also push the molded rehabilitation instrument shell upward. Furthermore, the adhesion between the two is reduced by the action of the demolding layer, so that the product can be demolded smoothly and the surface remains smooth and flat.

[0012] Preferably, the lower mold is provided with a sealing gasket, which is located between the lower mold and the upper mold.

[0013] By adopting the above technical solution, a sealing gasket can be set to achieve a sealing effect.

[0014] Preferably, the lower mold has corresponding round holes around its top, and the upper mold has corresponding cylinders fixedly installed around its bottom, with multiple cylinders matched to the corresponding round holes.

[0015] By adopting the above technical solution, the positioning function can be achieved by setting a circular hole and a cylinder.

[0016] Preferably, the top of the lower mold has two symmetrical mounting slots, and each mounting slot has a corresponding mounting block that is slidably installed therein. Both mounting blocks are fixedly installed to the first mold core.

[0017] By adopting the above technical solution, and by setting up mounting slots and mounting blocks, it is possible to achieve quick assembly and disassembly as well as positioning.

[0018] Preferably, corresponding positioning blocks are fixedly installed on both sides of the lower mold and the upper mold, and positioning columns are slidably installed on both positioning blocks. A positioning frame is fixedly installed on the top of the positioning column, and the positioning frame is fixedly installed on the base.

[0019] By adopting the above technical solution, positioning blocks and positioning columns are set to facilitate support and limiting.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the cooperation of a first mold core, etc., and through the cooperation of the mounting groove and mounting block, the first mold core can be directly disassembled. At this time, the two nuts can be rotated and disassembled, thereby releasing the positioning installation of the threaded rod. Then, the pull rod can be pulled to move and the threaded rod can be disassembled, thereby releasing the positioning installation of the second mold core. Mold cores of different shapes can be disassembled and replaced, thus facilitating the rapid injection molding production of rehabilitation instrument housings of different shapes, improving the convenience and flexibility of use.

[0022] 2. This application employs a release layer and other components to drive the upper mold to move upward. At this time, the electric telescopic rod is activated by control, and the output end of the electric telescopic rod pushes the top plate to move downward. The top plate moves upward and pushes the molded rehabilitation instrument shell to move upward as well. Furthermore, the release layer reduces the adhesion between the two, allowing the product to be demolded smoothly and maintaining a smooth and flat surface. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-6This application will be described in further detail.

[0031] This application discloses an injection mold for the housing of a rehabilitation device.

[0032] Reference Figure 1 , Figure 5 and Figure 6 The injection mold for the housing of the rehabilitation device includes a base 1 and an upper mold 3 connected to an external drive device. The drive device is a prior art product in the field, so its specific structure and usage are not described in detail. A lower mold 2 is fixedly installed on the top of the base 1. An injection port 4 is provided on the top of the upper mold 3. A lower mold opening 8 is provided on the lower mold 2. A first mold core 9 is provided inside the lower mold opening 8. An upper mold opening 18 is provided at the bottom of the upper mold 3. A second mold core 19 is provided inside the upper mold opening 18. A disassembly and assembly mechanism is provided on the upper mold 3. A material feeding mechanism is provided at the bottom of the lower mold 2. A limiting mechanism is provided on the lower mold 2 and the upper mold 3.

[0033] The disassembly and assembly mechanism includes two rectangular slots 22 symmetrically opened in the upper mold opening 18. A corresponding rectangular block 23 is slidably installed in each of the two rectangular slots 22. The two rectangular blocks 23 are fixedly installed with the second mold core 19. Two corresponding threaded rods 24 are slidably installed through one side of the upper mold 3. The two threaded rods 24 pass through the corresponding rectangular blocks 23. A corresponding nut 25 is screwed onto the exposed surface of the two threaded rods 24. A corresponding demolding layer 10 is provided in both the first mold core 9 and the second mold core 19. The same connecting plate 20 is fixedly installed at one end of the two threaded rods 24. A pull rod 21 is fixedly installed on one side of the connecting plate 20.

[0034] In use, by rotating and disassembling the two nuts 25, the positioning installation of the threaded rod 24 can be released, and the pull rod 21 can be pulled to move it. The threaded rod 24 can be disassembled, and the positioning installation of the second mold core 19 can be released. Mold cores of different shapes can be disassembled and replaced, thus facilitating the rapid injection molding production of rehabilitation instrument housings of different shapes and improving the convenience and flexibility of use.

[0035] Reference Figure 3-4 The feeding mechanism includes a support plate 26 fixedly installed on the same side of the two bases 1 close to each other. Two electric telescopic rods 14 are symmetrically fixedly installed on the top of the support plate 26. The output ends of the two electric telescopic rods 14 pass through the bottom of the first mold core 9 and are fixedly installed with a top plate 13. The top plate 13 is the same size and shape as the first mold core 9. A sealing gasket 15 is provided on the lower mold 2. The sealing gasket 15 is located between the lower mold 2 and the upper mold 3.

[0036] In use, by controlling the start of the electric telescopic rod 14, the output end of the electric telescopic rod 14 will push the top plate 13 to move downward. The top plate 13 moves upward and pushes the molded rehabilitation instrument shell to move upward as well. Under the action of the demolding layer 10, the adhesion between the two is reduced, so that the product can be demolded smoothly and the surface remains smooth and flat.

[0037] Reference Figure 3-5 The limiting mechanism includes corresponding circular holes 16 on the top four sides of the lower mold 2, and corresponding cylindrical cylinders 17 fixedly installed on the bottom four sides of the upper mold 3. Multiple cylindrical cylinders 17 are adapted to the corresponding circular holes 16. Two mounting slots 11 are symmetrically opened on the top of the lower mold 2. Corresponding mounting blocks 12 are slidably installed in the two mounting slots 11. The two mounting blocks 12 are fixedly installed with the first mold core 9. Corresponding positioning blocks 6 are fixedly installed on both sides of the lower mold 2 and the upper mold 3. Positioning pins 7 are slidably installed through the two positioning blocks 6. Positioning frames 5 are fixedly installed on the top of the positioning pins 7. The positioning frames 5 are fixedly installed on the base 1.

[0038] In use, the upper mold 3 is driven downward by an external device, and multiple cylinders 17 are inserted into the corresponding round holes 16 to ensure stability during downward movement. At this time, material is injected through the injection port 4 and fills the first mold core 9 and the second mold core 19, so that the rehabilitation instrument shell can be injection molded between the first mold core 9 and the second mold core 19.

[0039] The implementation principle of the injection mold for the rehabilitation device housing in this application embodiment is as follows: When in use, the upper mold 3 is driven to move downward by an external device, and multiple cylinders 17 are inserted into the corresponding round holes 16, thereby ensuring the stability during downward movement. At this time, material is injected through the injection port 4 and fills the first mold core 9 and the second mold core 19, so that the rehabilitation device housing can be injection molded between the first mold core 9 and the second mold core 19.

[0040] When demolding is required, the upper mold 3 is driven to move upward. At this time, the electric telescopic rod 14 is activated by control. The output end of the electric telescopic rod 14 will push the top plate 13 to move downward. The top plate 13 moves upward and pushes the molded rehabilitation instrument shell to move upward as well. Under the action of the demolding layer 10, the adhesion between the two is reduced, so that the product can be demolded smoothly and the surface remains smooth and flat.

[0041] When injection molding is required for the housing of rehabilitation instruments of different shapes, the first mold core 9 can be directly disassembled by the cooperation of the mounting groove 11 and the mounting block 12. At this time, the two nuts 25 can be rotated and disassembled, thereby releasing the positioning installation of the threaded rod 24. Then, the pull rod 21 can be pulled to move and the threaded rod 24 can be disassembled, thereby releasing the positioning installation of the second mold core 19. Mold cores of different shapes can be disassembled and replaced, thus facilitating the rapid injection molding production of rehabilitation instrument housings of different shapes and improving the convenience and flexibility of use.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
