Description

Technical Field

[0001] This utility model relates to the field of injection molding part grinding technology, specifically to an injection molding part grinding device. Background Technology

[0002] Plastic injection molding is a method of producing plastic products. Molten plastic is injected into a mold under pressure, and then cooled and solidified to obtain various desired plastic parts. After injection molding, the parts often require corresponding grinding equipment for polishing. With the development of technology, injection molding grinding equipment has greatly improved, bringing great convenience to injection molding production. However, current injection molding grinding equipment still has some shortcomings.

[0003] In the existing technology, it is not convenient to grind cylindrical and tubular injection molded parts with different inner and outer diameters. Furthermore, the existing equipment is prone to uneven grinding of the injection molded parts due to poor fixation before grinding, which in turn leads to uneven thickness of the cylindrical and tubular injection molded parts after grinding, resulting in damage to the workpiece. Utility Model Content

[0008] Furthermore, the base is provided with a toothed groove, and the first bevel gear and the second bevel gear are rotatably connected in the toothed groove. A plurality of first sliding grooves are provided in a cross shape in the base located on the outer periphery of the toothed groove. The first sliding grooves penetrate the upper end of the base. The first screw is rotatably connected in the first sliding groove, and the first slider is slidably connected in the first sliding groove.

[0009] Furthermore, the grinding mechanism includes a second motor and a mounting housing. The second motor is fixed to the upper end of the fixing plate, and the mounting housing is fixed to the output end of the second motor.

The first screw 404 is rotatably connected to the base 1. A second bevel gear 403 is fixedly connected to one end of the first screw 404. The second bevel gear 403 meshes with the first bevel gear 402. A first slider 405 is threaded onto the first screw 404. The clamping plate 406 is fixedly connected to the upper end of the first slider 405. The clamping plate 406 is slidably disposed on the upper end of the base 1. Several anti-slip strips 407 are fixedly connected to the inner side of the clamping plate 406, thereby improving the stability of the clamping plate 406 in clamping and fixing the injection molded part. The base 1 is equipped with an electric motor. The first motor 401 is fixedly connected to the motor slot 104. The motor slot 104 has heat dissipation holes 101 on both sides, which penetrate through both sides of the base 1 to prevent the first motor 401 from overheating. The base 1 has a toothed groove 102, and the first bevel gear 402 and the second bevel gear 403 are rotatably connected in the toothed groove 102. Several first sliding grooves 103 are arranged in a cross shape in the base 1 around the toothed groove 102. The first sliding grooves 103 penetrate through the upper end of the base 1. The first screw 404 is rotatably connected in the first sliding groove 103, and the first slider 405 is slidably connected in the first sliding groove 103 to improve the stability of the clamping plate 406 sliding on the upper end of the base 1.

[0026] like Figure 5-7As shown, in order to grind cylindrical and tubular injection molded parts of different sizes, the grinding mechanism 5 includes a second motor 501 and a mounting shell 502. The second motor 501 is fixed to the upper end of the fixing plate 3, and the mounting shell 502 is fixed to the output end of the second motor 501. The output end of the second motor 501 and the output end of the first motor 401 are on the same vertical axis. The mounting shell 502 is rotatably connected to the lower end of the fixing plate 3. The mounting shell 502 is provided with a second sliding groove 505. A second screw 506 is rotatably connected in the second sliding groove 505. The second screw 506 rotatably passes through one side of the mounting shell 502. A second slider 510 is threadedly connected to the second screw 506. The second slider 510 slides within the second sliding groove 505. A mounting plate 511 is fixedly connected to the lower end of the slider 510. A grinding part 512 is fixedly connected to one side of the mounting plate 511. A knob 507 is fixedly connected to one end of the second screw 506. A fastening ring 508 is threadedly connected to the second screw 506. A threaded ring 509 is fixedly connected to one end of the fastening ring 508. A threaded groove 504 is provided on one side of the mounting shell 502.

The limiting groove 301 is annular. The limiting member 503 slides and adapts to the limiting groove 301, thereby improving the stability of the mounting shell 502 rotating at the lower end of the fixing plate 3.

[0027] In use, the cylindrical or tubular injection molded part to be ground is placed between several clamping plates 406 on the upper end of the base 1. The output end of the first motor 401 drives the first bevel gear 402 to rotate, which in turn drives the second bevel gear 403 to rotate, which in turn drives the first screw 404 to rotate, which in turn drives the first slider 405 to slide in the first slide groove 103, which in turn drives the clamping plates 406 to slide on the base 1. The clamping plates 406 clamp and fix the injection molded part to the base 1, and the clamping position of the injection molded part is on the same vertical axis as the output end of the first motor 401 and the output end of the second motor 501. The hydraulic rod 2 drives the fixing plate 3 to rise and fall, so that the grinding part 512 extends into or outside the injection molded part, so that the grinding part 512 is... On one side of the inner or outer wall of the injection molded part, rotating the knob 507 drives the second screw 506 to rotate, which in turn drives the second slider 510 to slide in the second slide groove 505, which in turn drives the mounting plate 511 to move, which in turn drives the grinding part 512 to approach and fit against the inner or outer wall of the injection molded part. Rotating the fastening ring 508 causes the threaded ring 509 to be threaded into the threaded groove 504, thereby fixing the second screw 506 and the grinding part 512. The output end of the second motor 501 drives the mounting shell 502 to rotate, while the limiting member 503 slides in the limiting groove 301 to improve the stability of the rotation of the mounting shell 502. The rotation of the mounting shell 502 drives the grinding part 512 to fit against the inner or outer wall of the injection molded part and rotate to achieve grinding of the injection molded part.

[0028] In summary: In this embodiment of the utility model, the first motor 401 in the fixing mechanism 4 drives several clamping plates 406 to simultaneously clamp the injection molded part inward, thereby clamping the injection molded part to the central axis of the base 1, resulting in a good fixing effect; by rotating the knob 507, the second wheel is driven to rotate, thereby adjusting the position of the grinding part 512, thus enabling the grinding of injection molded parts of different sizes, and grinding of both the inner and outer walls of tubular injection molded parts, resulting in a good grinding effect.
