Description

Technical Field

[0001] The utility model relates to the field of injection molding fixtures, in particular to an adjustable injection molding shaping fixture. Background Art

[0002] An injection molding fixture is an auxiliary tool used to secure and support the molded part during the molding process to ensure the finished product maintains the correct shape and size. This fixture is not part of the mold that directly participates in the molding process, but is used in subsequent processing steps such as cooling, demolding, and inspection.

[0003] To improve cooling rates and ensure product quality during the cooling process of injection molded parts, targeted clamping is typically performed only on key areas prone to deformation, rather than wrapping the entire part. However, for injection molded parts of varying structures and sizes, the critical fixing positions and ideal fixing angles vary significantly. This increases the frequency of fixture changes and restricts production line flexibility.

[0004] Therefore, for the injection molded parts with different structures and sizes mentioned above, their key fixing positions and ideal fixing angles show significant differences, which leads to an increased replacement frequency of the molding fixture. An adjustable molding fixture can be designed to solve the above problem. Utility Model Content

[0005] In order to overcome the cooling problem during the cooling process of injection molded parts, in order to increase the cooling rate and ensure product quality, usually only key areas prone to deformation are fixed in a targeted manner rather than wrapping the entire part. However, the key fixing positions and ideal fixing angles of injection molded parts with different structures and sizes show significant differences, which leads to an increased frequency of replacement of the molding fixtures and restricts the flexibility of the production line.

[0008] Preferably, the push frame and the lift frame are both rotatably connected to two turntables; the turntables are fixedly connected to a hexagonal shaft; and the hexagonal shafts are slidably connected to three slides.

[0009] Preferably, the slides are all fixedly connected with slide bars; the slide bars are all slidably connected with replaceable clamping blocks; and the replaceable clamping blocks are all provided with sliding grooves.

[0010] Preferably, screw hole disks are fixed on both sides of the hexagonal shaft; a plurality of screw holes are provided on the screw hole disks, and bolts are fitted through the screw hole gaps on the screw hole disks; and the bolts are also fitted with the clearances of the push frame or the lifting frame.

[0013] Preferably, a second gear is fixed to the longitudinal threaded shaft; a second chain is engaged with the outer side of the second gear; a rocker plate is engaged with the lower end of the first chain and the front end of the second chain, and the rocker plates are rotatably connected to the chassis; the diameter of the rocker plate is larger than the first gear and the second gear.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up the rotation adjustment component and the displacement adjustment component, the user can flexibly adjust the replaceable clamp according to the key fixing position and ideal fixing angle of the injection molded part, so as to reduce the replacement frequency of the molding fixture, thereby improving work efficiency. In addition, when the groove on the replaceable clamp cannot fit the injection molded part, the replaceable clamp can be pulled out from the slide bar and the appropriate replaceable clamp can be inserted, thereby further improving the adjustment flexibility of the fixture.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See also Figures 1-6 The utility model provides an embodiment: an adjustable injection molding part molding fixture, including a push frame 1 and a lifting frame 2 arranged at the front end of the push frame 1, and also including a rotation adjustment component installed on the push frame 1 and the lifting frame 2, and a displacement adjustment component arranged at the lower ends of the push frame 1 and the lifting frame 2; the rotation adjustment component includes a turntable 301, a hexagonal shaft 302, a slide 303, a replaceable clamp 304, a slide bar 305, a slide groove 306, a screw hole plate 307, a bolt 308, and a turning handle 309; the displacement adjustment component includes a chassis 401, a guide rail 402, a horizontal threaded shaft 403, a first gear 404, a first chain 405, a longitudinal threaded shaft 406, a second gear 407, a second chain 408, and a rocker plate 409.

[0025] See also Figure 2-Figure 6306 is provided on each of the replaceable clamping blocks 304; and a screw hole disk 307 is fixed on both sides of the hexagonal shaft 302; a plurality of screw holes are provided on the screw hole disk 307, and a bolt 308 is fitted through the screw hole gap on the screw hole disk 307; and the bolt 308 is also fitted with a clearance between the push frame 1 or the lift frame 2; a chassis 401 is provided at the lower end of the push frame 1; a guide rail 402 is fixed at the lower end of the chassis 401; and the guide rail 402 is connected to the push frame 1 sliding connection; two horizontal threaded shafts 403 are provided at the upper end of the guide rail 402, and the horizontal threaded shafts 403 are rotatably connected to the chassis 401; the rear ends of the horizontal threaded shafts 403 pass through the chassis 401 and are fixedly connected to the first gear 404; the outer side of the first gear 404 is jointly engaged with a first chain 405; the front end of the chassis 401 is rotatably connected to two longitudinal threaded shafts 406; the longitudinal threaded shafts 406 are each fixedly connected to a second gear 407; the outer side of the second gear 407 is jointly engaged with a second chain 408; the lower end of the first chain 405 and the front end of the second chain 408 are both engaged with a rocker plate 409, and the rocker plate 409 is rotatably connected to the chassis 401; the diameter of the rocker plate 409 is larger than the first gear 404 and the second gear 407.

[0026] When in use, after unscrewing the bolt 308, the hexagonal shaft 302 and the slide 303 can be rotated by turning the handle 309 to adjust the angle of the slide 303, and then the bolt 308 is screwed on again and screwed into the screw hole of the screw hole plate 307 to fix the fixed angle of the slide 303 by fixing the screw hole plate 307. Then, the replaceable clamping block 304 is slid on the hexagonal shaft 302, and the rocker plate 409 is shaken to rotate the second chain 408. The second chain 408 rotates the longitudinal threaded shaft 406 through the second gear 407, and the rotation of the longitudinal threaded shaft 406 causes the lifting frame 2 to rise and fall, so as to flexibly adjust the replaceable clamping block 304 according to the key fixing position and the ideal fixing angle of the injection molded part, thereby improving work efficiency.

[0027] Subsequently, the rocker plate 409 is shaken to rotate the first chain 405, which rotates the transverse threaded shaft 403 through the first gear 404. The rotation of the transverse threaded shaft 403 then moves the push frame 1 forward to clamp the injection molded part. Because the diameter of the rocker plate 409 is larger than the first gear 404 and the second gear 407, the rocker plate 409 can accelerate when driving the first gear 404 through the first chain 405 or when driving the second gear 407 through the second chain 408, thereby further improving work efficiency.

[0028] When the groove on the replaceable clamping block 304 cannot fit the injection molded part, the replaceable clamping block 304 can be pulled out from the slide bar 305 and a suitable replaceable clamping block 304 can be inserted, thereby further improving the adjustment flexibility of the clamp.

[0029] Through the above steps, by setting the rotation adjustment component and the displacement adjustment component, the user can flexibly adjust the replaceable clamp 304 according to the key fixing position and the ideal fixing angle of the injection molded part, so as to reduce the replacement frequency of the shaping fixture, thereby improving work efficiency. When the groove on the replaceable clamp 304 cannot fit the injection molded part, the replaceable clamp 304 can be pulled out from the slide bar 305 and the appropriate replaceable clamp 304 can be inserted, thereby further improving the adjustment flexibility of the clamp.
