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] Example 1

[0028] Please see Figure 1-8 A positioning component for a high-efficiency injection molding machine includes a base 1 and vertical plates 2 fixedly installed on the top of the base 1 near the left and right sides. A placement platform 3 is fixedly installed on the top of the vertical plates 2. A movable plate 4 is provided on the top of the placement platform 3 near the upper left and right sides. A positioning plate 5 is fixedly installed on the opposite side of the movable plate 4. A clamping component 6 is installed in the middle of the top of the base 1, and an auxiliary component 7 is installed on the bottom of the placement platform 3 near the right side. The clamping component 6 can drive the positioning plates 5 on both sides to move relative to each other, while the auxiliary component 7 can clamp the front and rear sides of the mold and play a centering role. The clamping component 6 and the auxiliary component 7 can achieve centered clamping and positioning of the injection mold, which is beneficial to the subsequent work.

[0029] In this example, the clamping assembly 6 includes a hydraulic push rod A61 fixedly installed at the top center of the base 1 and a push plate 62 fixedly installed at the power end of the hydraulic push rod A61. An n-shaped plate 63 is provided on the top of the push plate 62 near the upper left and right sides. A swing frame 64 is movably installed on the opposite side of the n-shaped plate 63 near the front and rear sides. The end of the swing frame 64 away from the n-shaped plate 63 is movably installed on an adjacent vertical plate 2. A translation plate 66 is fixedly installed on the opposite side of the n-shaped plate 63 near the top. A translation plate 66 is fixedly installed on the top of the translation plate 66 near the opposite side. There is a square rod 67. The top of the placement platform 3 is provided with square openings near the left and right sides. The upper ends of the square rods 67 pass through the inner cavities of the adjacent square openings and are fixedly installed with adjusting plates 68. Hydraulic push rods B69 are fixedly installed at the middle of the top of the adjusting plates 68. The power ends of the hydraulic push rods B69 are fixedly installed on the adjacent moving plates 4. They can drive the positioning plates 5 on both sides to move relative to each other, so as to clamp and position the injection mold. The height of the positioning plates 5 can be adjusted by setting the hydraulic push rods B69, so as to clamp and position injection molds of different sizes.

[0030] Specifically, limit telescopic rods 621 are fixedly installed at the bottom of the push plate 62 near the left and right sides, and the lower ends of the limit telescopic rods 621 are fixedly installed on the base 1, which serves to guide and limit the movement of the push plate 62.

[0031] Specifically, a fixed shaft 65 is slidably installed through the inner cavity of the swing frame 64, and the inner end of the fixed shaft 65 is fixedly installed on the push plate 62. The fixed shaft 65 can drive the swing frame 64 to move, which is conducive to adjusting the position of the positioning plate 5.

[0032] Specifically, a sliding frame 41 is slidably installed on the bottom of the movable plate 4 near the front and rear sides, and a roller 42 is fixedly installed on the bottom of the sliding frame 41. Two sliding grooves are opened on the left and right sides of the top of the placement platform 3, and the sliding grooves are arranged front and rear. The outer side of the roller 42 is slidably installed in the inner cavity of the adjacent sliding groove, which plays a role in guiding and limiting the movement of the movable plate 4.

[0033] In this embodiment: During use, the injection mold can be placed on the placement platform 3. After placement, the hydraulic push rod A61 can be activated. When the hydraulic push rod A61 runs, it will drive the push plate 62 to move downward. When the push plate 62 moves downward, it will drive the swing frame 64 to swing inward through the fixed shaft 65. When the swing frame 64 swings inward, it will drive the adjacent n-shaped plate 63 to move relative to each other. When the n-shaped plate 63 moves relative to each other, it will drive the adjacent translation plate 66 to move relative to each other. When the translation plate 66 moves relative to each other, it will drive the adjustment plates 68 on both sides to move relative to each other through the adjacent square rod 67. When the adjustment plates 68 move relative to each other, it will drive the moving plates 4 on both sides to move relative to each other through the adjacent hydraulic push rod B69. When the moving plates 4 move relative to each other, they will also drive the roller 42 to roll in the sliding groove, which will play a guiding and limiting role. In addition, when the moving plates 4 move relative to each other, they will drive the adjacent positioning plate 5 to move relative to each other, thereby realizing the clamping and positioning of the two sides of the injection mold. The height of the positioning plate 5 can be adjusted by the setting of the hydraulic push rod B69, which is beneficial for clamping and positioning injection molds of different sizes.

[0034] Example 2

[0035] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 2-5 and Figure 7-8The auxiliary component 7 includes two rack plates 71 located at the bottom of the placement platform 3 near the right side, with the rack plates 71 arranged front to back. Movable gears 72 are meshed on the top of each rack plate 71 near the left side. Threaded rods A73 and B74 are fixedly installed at the middle of opposite sides of the movable gears 72, and a transmission rod is fixedly installed at the opposite ends of threaded rods A73 and B74. A vertical plate is movably installed on the outer side of the transmission rod via a bearing. The top of the vertical plate is fixedly installed on the placement platform 3. Threaded sleeves 75 are threadedly installed on the outer sides of threaded rods A73 and B74 near their opposite ends. A shaped rod 76 is fixedly installed at the bottom of each threaded sleeve 75. A sliding plate 77 is fixedly installed at the end of each shaped rod 76 away from the adjacent threaded sleeve 75, and the bottom of each sliding plate 77 is slidably installed on the placement platform 3. An auxiliary plate 78 is provided on the opposite side of each sliding plate 77.

[0036] Specifically, U-shaped rods 711 are fixedly installed on the opposite side of the rack plate 71 near the right side, and the ends of the U-shaped rods 711 away from the adjacent rack plates 71 are fixedly installed on the adjacent rollers 42 respectively.

[0037] Specifically, sliding rods 771 are slidably installed on the sliding plate 77 near the left and right sides, and the opposite ends of the sliding rods 771 are fixedly installed on the adjacent auxiliary plates 78. Return springs 772 are respectively sleeved on the outer side of the sliding rods 771. The two ends of the return springs 772 are fixedly installed on the adjacent sliding plate 77 and auxiliary plate 78 respectively. The return springs 772 can play a buffering role to avoid damage caused by excessive movement distance.

[0038] In this embodiment: when the roller 42 moves relative to the mold, it drives the rack plate 71 on the right side to move to the left via the U-shaped rod 711. When the rack plate 71 moves to the left, it drives the adjacent movable gear 72 to rotate. When the movable gear 72 rotates, it drives the threaded rod A73 and threaded rod B74 to rotate. When the threaded rod A73 and threaded rod B74 rotate, they drive the adjacent threaded sleeve 75 to move relative to the mold. When the threaded sleeve 75 moves relative to the mold, it drives the sliding plates 77 on the front and rear sides to move relative to the mold via the adjacent irregular rod 76. When the sliding plates 77 move relative to the mold, the sliding rod 771 and the return spring 772 drive the adjacent auxiliary plate 78 to move relative to the mold, thereby clamping the front and rear sides of the injection mold and facilitating its centering and positioning.

[0039] Working Principle: During use, the injection mold can be placed on the placement table 3. After placement, the hydraulic push rod A61 is activated. The operation of the hydraulic push rod A61 drives the push plate 62 downwards. As the push plate 62 moves downwards, it drives the swing frame 64 to swing inwards via the fixed shaft 65. The inward swing of the swing frame 64 causes the adjacent n-shaped plates 63 to move relative to each other. The relative movement of the n-shaped plates 63 causes the adjacent translation plates 66 to move relative to each other. The relative movement of the translation plates 66 causes the adjustment plates 68 on both sides to move relative to each other via the adjacent square rod 67. The relative movement of the adjustment plates 68 causes the moving plates 4 on both sides to move relative to each other via the adjacent hydraulic push rod B69. The relative movement of the moving plates 4 also causes the rollers 42 to roll within the sliding groove, serving as guides and limits. Furthermore, the relative movement of the moving plates 4 causes the adjacent positioning plates 5 to move relative to each other. This allows for clamping and positioning of both sides of the injection mold. The height of the positioning plate 5 can be adjusted by the hydraulic push rod B69, which is beneficial for clamping and positioning injection molds of different sizes. When the roller 42 moves relative to each other, it drives the rack plate 71 on the right side to move to the left through the U-shaped rod 711. When the rack plate 71 moves to the left, it drives the adjacent movable gear 72 to rotate. When the movable gear 72 rotates, it drives the threaded rod A73 and threaded rod B74 to rotate. When the threaded rod A73 and threaded rod B74 rotate, they drive the adjacent threaded sleeve 75 to move relative to each other. When the threaded sleeve 75 moves relative to each other, it drives the sliding plates 77 on the front and rear sides to move relative to each other through the adjacent irregular rod 76. When the sliding plates 77 move relative to each other, the sliding rod 771 and the return spring 772 drive the adjacent auxiliary plate 78 to move relative to each other, thus achieving clamping of the front and rear sides of the injection mold and facilitating its centering and positioning.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
