Description

Technical Field

[0001] This invention belongs to the field of injection molding and relates to static emulsification technology, specifically a static emulsification mixing micro-molding device. Background Technology

[0002] Static emulsification micro-injection molding technology uses ultrasonic vibration to hammer polymer particles, causing them to melt and plasticize. The energy of the ultrasonic waves is converted into heat energy, which causes the polymer particles to melt and form a melt. Then, the melt is directly pushed into the mold cavity through an ultrasonic tool head or injection plunger to complete the injection molding.

[0003] However, the following problems exist when implementing the above technical solutions: different emulsifying sleeves need to be assembled according to different emulsifying injection hole sizes when using the above devices. The molding cavity and the fixing plate in the above devices can be detachably connected, thus making them suitable for micro-injection molding of different injection molding cavities. The melting is transferred between the molding cavity and the moving mold fixing plate in the injection direction through the inner slope of the emulsifying sleeve. Therefore, when changing the micro-injection molding cavity, the emulsifying sleeve with the corresponding inner slope angle needs to be replaced. There are many types of emulsifying sleeves required for use, which increases the manufacturing and usage costs.

[0004] Therefore, the present invention proposes a static emulsification and mixing microforming device. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a static emulsification and mixing microforming device, which solves the problem that existing static emulsification microforming devices require replacing the corresponding emulsification sleeve when changing to different emulsion injection molding processes, thus increasing usage costs.

[0006] To achieve the above objectives, an embodiment of the first aspect of the present invention provides a static emulsification and mixing microforming apparatus, comprising: a forming cavity, an emulsification sleeve, and a substrate, wherein the forming cavity and the emulsification sleeve are detachably connected, the emulsification sleeve and the substrate are detachably connected, the side of the forming cavity near the substrate is attached to the substrate, and an adjustment mechanism is provided inside the emulsification sleeve, the adjustment mechanism comprising: The spring block is frustum-shaped, and its cross-section decreases in size towards the molding cavity. The spring block is fixedly connected to the side of the emulsion sleeve away from the substrate, and a pendant is rotatably connected to the side of the spring block near the molding cavity. A plurality of mixing rods are slidably connected to the inside of the emulsifying sleeve. One end of each mixing rod is fixedly connected to the inside of the spring block.

A plurality of intermediate transfer rods are provided, each of which is rotatably connected to a mixing rod. A rotating block is slidably connected to the surface of each intermediate transfer rod, and a transmission component is provided between the rotating block and the adjusting block to realize the rotation of the rotating block.

[0007] Optionally, the surface of the emulsifying sleeve is provided with multiple grooves, which are symmetrically arranged. The cross-section of the groove is arc-shaped facing the substrate, and the center of the arc is located on the substrate surface. Multiple fixing posts are slidably connected inside the substrate, and the fixing posts are adapted to the grooves.

[0008] Optionally, the substrate surface is provided with a plurality of movable grooves, the movable grooves are adapted to the fixed posts, and a spring is fixedly connected between the movable grooves and the fixed posts.

[0009] Optionally, each of the rotating blocks has a transfer groove on its surface, the transfer groove is adapted to the transfer rod, and a transfer spring is fixedly connected between the transfer rod and the transfer groove.

[0010] Optionally, the transmission assembly includes a rotating shaft fixed to the surface of the adjusting block, and the surface of the adjusting block is provided with an arc groove, the rotating shaft being adapted to the arc groove.

[0011] Optionally, an operating ring is slidably connected to the surface of the control rod, and a plurality of fixed teeth are fixedly connected to the operating ring near the side of the emulsifying sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: an elastic spring block is provided on the side of the emulsifying sleeve close to the molding cavity, and a slidable and rotatable mixing rod is provided between the emulsifying sleeve and the spring block. When the mixing rod moves inside the emulsifying sleeve, it can cause the mixing rod inside the spring block to rotate, thereby changing the diameter of the side of the spring block close to the molding cavity. Thus, when changing different molding cavities in the static emulsification device, the diameter of one end of the spring block can be adjusted according to the diameter of the molding cavity, ensuring that the surface of the upper part of the spring block can fit with the molding opening of the molding cavity, enabling the emulsifying sleeve to fit with different molding cavities and increasing the applicability of the emulsifying sleeve.

[0016] like Figure 1-6 As shown, a static emulsification and mixing microforming device includes a forming cavity 1, an emulsification sleeve 2, and a substrate 3. The forming cavity 1 and the emulsification sleeve 2 are detachably connected, and the emulsification sleeve 2 and the substrate 3 are detachably connected.

The side of the mixing rod 43 away from the emulsifying sleeve 2 is fixedly connected to the inside of the spring block 41. The plurality of mixing rods 43 are spaced equally apart. An adjusting block 44 is rotatably connected to the end of the mixing rod 43 away from the spring block 41. The adjusting block 44 is threadedly connected to a control rod 45. A connecting rod 46 is fixedly connected between the adjusting blocks 44. A plurality of intermediate transfer rods 47 are rotatably connected to a mixing rod 43. A rotating block 48 is slidably connected to the surface of the intermediate transfer rod 47. A transmission component for rotating the rotating block 48 is provided between the rotating block 48 and the adjusting block 44. In practical applications, this static emulsification micro-molding device has an elastic spring block 41 on the side of the emulsification sleeve 2 close to the molding cavity 1, and a slidable and rotatable mixing rod 43 between the emulsification sleeve 2 and the spring block 41. When the mixing rod 43 moves inside the emulsification sleeve 2, it can cause the mixing rod 43 inside the spring block 41 to rotate, thereby changing the diameter of the side of the spring block 41 close to the molding cavity 1. When the static emulsification device is used to change to different molding cavities 1, the diameter of one end of the spring block 41 can be adjusted according to the diameter of the molding cavity 1, ensuring that the surface of the hanging block 42 on the spring block 41 can fit with the molding opening of the molding cavity 1, so that the emulsification sleeve 2 can fit with different molding cavities 1, increasing the applicability of the emulsification sleeve 2. In some specific implementations, the surface of the emulsifying sleeve 2 is provided with a plurality of grooves 51, the plurality of grooves 51 are symmetrically arranged, the cross-section of the groove 51 is arc-shaped facing the substrate 3, and the center of the arc is located on the surface of the substrate 3. A plurality of fixing posts 52 are slidably connected inside the substrate 3, and the fixing posts 52 are adapted to the grooves 51. In a further embodiment, a plurality of movable grooves 53 are formed on the surface of the substrate 3, the movable grooves 53 are adapted to the fixed posts 52, and a spring 54 is fixedly connected between the movable grooves 53 and the fixed posts 52. In some specific implementations, the surface of the rotating block 48 is provided with a transfer groove 61, the transfer groove 61 is adapted to the transfer rod 47, and a transfer spring 62 is fixedly connected between the transfer rod 47 and the transfer groove 61. In some specific implementations, the transmission assembly includes a rotating shaft 71 fixed to the surface of the adjusting block 44, and the surface of the rotating block 48 is provided with an arc groove 72, and the rotating shaft 71 is adapted to the arc groove 72.

A fixed groove 83 is opened on the surface of the emulsifying sleeve 2. Several positioning teeth 84 are fixedly connected inside the fixed groove 83. The positioning teeth 84 are evenly fixed on the inner surface of the fixed groove 83. The fixed teeth 82 and the positioning teeth 84 mesh. The working principle of this invention is as follows: When changing the molding cavity 1, the operating ring 81 is slid towards the substrate 3, causing the fixed tooth 82 to disengage from the positioning tooth 84. At this time, the operating ring 81 can be rotated. The rotation of the operating ring 81 drives the control rod 45 to rotate. The rotation of the control rod 45 drives the adjusting block 44 to slide. The sliding of the adjusting block 44 causes the rotating block 48 to rotate, which in turn causes the mixing rod 43 to rotate inside the emulsifying sleeve 2 and the spring block 41. The rotation of the mixing rod 43 causes the spring block 41 to change its diameter. The vertical block 42 on the side of the spring block 41 near the molding cavity 1 can be completely fitted with the injection groove inside the molding cavity 1.
