[0002] The locating ring is a key component in the injection mold, mainly used to ensure the coaxiality between the mold and the injection molding machine nozzle, and at the same time guide the molten plastic into the mold cavity. Traditional locating rings are mostly simple cylindrical structures, relying on a single vertical mating surface and the injection molding machine template or mold panel for positioning; traditional flat or single-bevel locating rings are prone to mold offset due to slight misalignment under high temperature and high pressure, affecting the quality of injection molding; during long-term repeated disassembly and assembly, the metal contact surface is prone to wear, resulting in an increase in the mating clearance, requiring frequent replacement; complex molds (such as multi-cavity molds or stacked molds) require higher precision alignment requirements, and the existing locating rings lack multi-level guiding functions and are difficult to meet the needs; the core of the present invention is to propose a locating ring mold with multi-level stepped bevels, which significantly improves positioning accuracy and durability through layered guidance and progressive matching.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 2 As shown, the structure and function of the positioning ring are described in detail below;

[0036] When using, such as Figure 4 As shown, the molten raw material of the positioning ring is injected into the forming die 5, and the positioning ring raw material is extruded and formed by the extrusion of the fastening die 7 and the forming die 5. At the same time, the inner hole mechanism 6 and the insertion mechanism 8 are inserted into the fastening die 7 and the forming die 5, and the positioning ring raw material is extruded and formed, and a plurality of stepped positioning inclined surfaces 11 are formed on the positioning ring;

[0037] like Figure 5 As shown, the forming mold 5 is rotatably connected to two support rings 22, and the two support rings 22 are respectively fixedly connected to two support brackets 21;

[0038] A storage box 31 is fixedly connected between the bottoms of the two support brackets 21, a buffer plate 32 is slidably connected inside the storage box 31, and a compression spring is fixedly connected between the buffer plate 32 and the bottom of the storage box 31;

[0039] The support ring 22 is fixedly connected to an injection cavity 4, a connecting pipe 42 is fixedly connected to the injection cavity 4, and a connecting hole I 41 is provided on the injection cavity 4;

[0040] The molding die 5 includes two communicating cavities 51, which are rotatably connected to two support rings 22 respectively. A communicating hole II 54 is provided on the communicating cavity 51, and the communicating hole II 54 can be dislocated or connected with the communicating hole I 41. A power mechanism for driving the communicating cavity 51 to rotate is fixedly connected to the support ring 22. An outer mold 52 is fixedly connected between the two communicating cavities 51, and the outer mold 52 is connected to the communicating cavity 51. A mounting bracket 53 is fixedly connected to the outer mold 52.

[0041] The inner hole mechanism 6 includes a plurality of telescopic mechanisms I 61, each of which is fixedly connected to the mounting bracket 53. An inner hole column 63 is fixedly connected to the telescopic end of one of the telescopic mechanisms I 61, and inner hole sleeves 62 are fixedly connected to the telescopic ends of the remaining telescopic mechanisms I 61. The plurality of inner hole sleeves 62 are mutually sleeved and slidably connected, and the inner hole column 63 is slidably connected to the inner hole sleeves 62 located inside. The plurality of inner hole sleeves 62 are all slidably connected to the bottom of the outer mold 52.

[0042] The inner hole column 63 and the inner hole sleeve 62 are both provided with an air extraction channel 64, and the inner hole column 63 and the inner hole sleeve 62 are both provided with an air extraction hole 65, and the air extraction hole 65 is connected to the air extraction channel 64. The inner hole column 63 and the inner hole sleeve 62 are both fixedly connected to a telescopic mechanism II 66, and a blocking block is fixedly connected to the telescopic end of the telescopic mechanism II 66, and the blocking block can block the air extraction channel 64;

[0043] The fastening mold 7 includes a telescopic mechanism III 71, which is fixedly connected to the mounting bracket 53. A swing motor 72 is fixedly connected to the telescopic end of the telescopic mechanism III 71. An inner mold 73 is fixedly connected to the output shaft of the swing motor 72. The inner mold 73 can be inserted into the outer mold 52. A sleeve 74 is fixedly connected to the inner mold 73.

[0044] The insertion mechanism 8 includes a plurality of telescopic mechanisms IV 81, each of which is fixedly connected to the inner mold 73. An insertion column 83 is fixedly connected to the telescopic end of one of the telescopic mechanisms IV 81, and an insertion sleeve 82 is fixedly connected to the telescopic ends of the remaining telescopic mechanisms IV 81. The lower end of the insertion sleeve 82 is inclined, and the plurality of insertion sleeves 82 are mutually sleeved and slidably connected. The insertion column 83 is slidably connected to the insertion sleeve 82 located inside. The plurality of insertion sleeves 82 are all slidably connected to the sleeve 74.

[0045] When using, such as Figure 4 As shown, the molten raw material of the positioning ring is injected into the connecting pipe 42, the positioning ring raw material enters the injection cavity 4, and enters the connecting cavity 51 through the connecting hole I 41 provided on the injection cavity 4 and the connecting hole II 54 provided on the connecting cavity 51. The positioning ring raw material enters the outer mold 52 through the connecting cavity 51;

[0046] The air extraction hole 65 is connected to the air pump in advance, and the telescopic mechanism II 66 is started. The telescopic mechanism II 66 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 66 drives the blocking block to move, so that the blocking block no longer blocks the air extraction channel 64. Then, the air extraction hole 65 vacuumizes the space between the outer mold 52 and the inner mold 73 through the air extraction channel 64. Then, the telescopic mechanism II 66 is started, and the telescopic end of the telescopic mechanism II 66 drives the blocking block to move, so that the blocking block blocks the air extraction channel 64. Figure 10 As shown;

[0047] Then, the telescopic mechanism III 71 is started. The telescopic mechanism III 71 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 71 drives the swing motor 72 to move upward. The swing motor 72 drives the inner mold 73 to move upward. The inner mold 73 slides upward in the outer mold 52, so that the molten material of the positioning ring enters between the inner mold 73 and the outer mold 52.

[0048] At the same time, according to the size of the inner hole diameter of the positioning ring 1 to be formed, the telescopic mechanism I 61 is started. The telescopic mechanism I 61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 61 drives the inner hole sleeve 62 and the inner hole column 63 to move upward. The outer diameter of the rising inner hole sleeve 62 is the inner hole diameter of the positioning ring 1. The number of rising inner hole sleeves 62 is controlled, and the inner hole diameter of the positioning ring 1 is further controlled.

[0049] At the same time, the telescopic mechanism IV 81 is started. The telescopic mechanism IV 81 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV 81 drives the insert sleeve 82 and the insert column 83 to move, adjusting the height position of the multiple insert sleeves 82 between the outer mold 52 and the inner mold 73, thereby forming a shield for the raw material of the positioning ring 1. The lower end of the insert sleeve 82 is tapered to form a positioning inclined surface 11.

[0050] like Figure 1 As shown, when it is necessary to form a positioning ring 1 with two positioning inclined surfaces 11, the inner hole column 63 rises, the multiple inner hole sleeves 62 do not rise, and the two insert sleeves 82 rise. The two insert sleeves 82 rise to different heights, that is, the height of the inner insert sleeve 82 rising is less than the height of the outer insert sleeve 82 rising, thereby forming a positioning ring 1 with a stepped positioning inclined surface 11;

[0051] Furthermore, after the positioning ring 1 is cooled and formed, the power mechanism is started, which is preferably a servo motor. The output shaft of the power mechanism drives the forming mold 5 to flip. At this time, the connecting hole II54 and the connecting hole I41 are misaligned, and no positioning ring raw material enters the forming mold 5. After the forming mold 5 is flipped 180°, the telescopic mechanism III71 and the swing motor 72 are started. The swing motor 72 is preferably a servo motor. The telescopic end of the telescopic mechanism III71 first drives the inner mold 73 and the outer mold 52 to separate, and the output shaft of the swing motor 72 drives the inner mold 73 to swing. The positioning ring 1 in the outer mold 52 falls out into the storage box 31. After the buffer plate 32 is used for shock absorption, the positioning ring 1 is stored in the storage box 31.
