Description

Technical Field

[0001] The utility model relates to the technical field of injection molded part jigs, in particular to a fixture tool for fixing injection molded parts. Background Art

[0002] Injection molded parts are various products or components manufactured by the injection molding process, including common plastic products in daily life such as plastic buckets, plastic cups, and plastic bowls. After the injection molding of such injection molded parts, further processing is required, including trimming, removing excess materials, surface treatment, etc., to meet the final product requirements.

[0003] During the subsequent processing of injection molded parts, jigs are needed to fix and clamp the injection molded parts to facilitate processing. When the existing jigs clamp the injection molded parts, usually the clamping blocks on both sides exert force on the injection molded parts from both sides to clamp and fix the injection molded parts. Since the centers of injection molded part products such as plastic buckets, plastic cups, and plastic bowls are all in a hollow state, excessive force exerted by such jigs is likely to cause the formed injection molded part products to crack and be damaged.

[0004] Therefore, we propose a fixture tool for fixing injection molded parts to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a fixture tool for fixing injection molded parts.

Two moving blocks arranged corresponding to each other left and right are sleeved on the bidirectional threaded rod in a threaded manner. U-shaped blocks are fixedly connected to the lower ends of the two moving blocks. First rotating rods are rotatably connected in the grooves of the two U-shaped blocks.

[0008] Preferably, first bevel gears are rotatably connected to the front ends of the two U-shaped blocks. The two first bevel gears are coaxially and fixedly connected to the two first rotating rods respectively. A bidirectional telescopic rod is arranged below the disc. Symmetrically arranged second bevel gears are fixedly connected to the two telescopic ends of the bidirectional telescopic rod. The two second bevel gears are respectively meshed with the two first bevel gears.

[0009] Preferably, extension plates are fixedly connected to the front ends of both of the moving blocks, connecting rods are fixedly connected to the lower ends of both of the extension plates, rings are fixedly connected to the lower ends of both of the connecting rods, and the telescopic parts at the left and right ends of the bidirectional telescopic rod are rotatably connected to the two rings respectively.

[0011] Preferably, an activity opening is formed in the disc, and the transmission belt penetrates through the activity opening.

[0012] Preferably, a rotating handle is rotatably connected to one end of one of the first support plates away from the other first support plate, and the rotating handle is coaxially and fixedly connected to the bidirectional threaded rod.

[0013] Compared with the prior art, the advantages of this device are as follows:

[0014] The injection molded parts products such as plastic buckets, plastic cups and plastic bowls are clamped through the two electric grippers from the openings of the injection molded parts products, so as to avoid damaging the injection molded parts products by applying force from both sides of the injection molded parts products.

[0015] The two second bevel gears drive the corresponding first bevel gears to rotate, thereby driving the two first rotating rods to rotate relatively, and driving the two electric grippers to rotate relatively, so as to adapt to clamping injection molded parts products in a bowl shape.

[0016] To sum up, this device can clamp the injection molded parts products from the openings of the injection molded parts products such as plastic buckets, plastic cups and plastic bowls, so as to avoid damaging the injection molded parts products by applying force from both sides of the injection molded parts products, and can adapt to injection molded parts products with different calibers, and can adjust the angle of the electric grippers to clamp injection molded parts products with different shapes.

[0022] Refer to Figures 1 - 3 , a fixing jig tool for injection molded parts, including a disc 1. Two first support plates 2 arranged corresponding to each other left and right are fixedly connected to the lower end of the disc 1. A bidirectional threaded rod 3 is rotatably connected between the two first support plates 2. Two moving blocks 4 arranged corresponding to each other left and right are threadedly sleeved on the bidirectional threaded rod 3. U-shaped blocks 5 are fixedly connected to the lower ends of the two moving blocks 4. First rotating rods 6 are rotatably connected in the grooves of the two U-shaped blocks 5. Electric grippers 7 are fixedly sleeved on the two first rotating rods 6. One end of one of the first support plates 2 away from the other first support plate 2 is rotatably connected to a rotating handle 20, and the rotating handle 20 is coaxially and fixedly connected to the bidirectional threaded rod 3. The injection molded part products such as plastic buckets, plastic cups, and plastic bowls can be clamped through the two electric grippers 7 from the openings of the injection molded part products, thereby avoiding damage to the injection molded part products caused by applying force from both sides of the injection molded part products. By rotating the rotating handle 20, the bidirectional threaded rod 3 is driven to rotate. The two moving blocks 4 are respectively threadedly sleeved on two parts of the bidirectional threaded rod 3 with opposite thread directions. The two moving blocks 4 are frictionally attached to the disc 1 to play a limiting role, so that the two moving blocks 4 drive the two electric grippers 7 to approach or move away from each other, so as to adapt to clamping injection molded part products with different diameters. The electric gripper 7 is a prior art and will not be described in detail here.

[0023] At the front ends of both U-shaped blocks 5, first bevel gears 8 are rotatably connected.

An activity opening is formed in the disc 1, and the transmission belt 18 passes through the activity opening. The motor 19 drives the second rotating rod 16 to rotate. The second pulley 17 rotates and drives the first pulley 14 to rotate through the transmission belt 18, so that the bidirectional telescopic rod 9 rotates. The second bevel gears 10 symmetrically arranged at both ends thereof rotate. The two second bevel gears 10 drive the corresponding first bevel gears 8 to rotate, so as to drive the two first rotating rods 6 to rotate relatively, and drive the two electric grippers 7 to rotate relatively to adapt to clamping an injection-molded product in a bowl shape.

[0025] When using the present utility model, by rotating the rotating handle 20, the bidirectional threaded rod 3 is driven to rotate, so that the two moving blocks 4 drive the two electric grippers 7 to approach or move away from each other, so as to adapt to clamping injection-molded products with different calibers. The two electric grippers 7 clamp the injection-molded products from the openings of injection-molded products such as plastic barrels, plastic cups and plastic bowls, so as to avoid damaging the injection-molded products by applying force from both sides of the injection-molded products. The second pulley 17 rotates and drives the first pulley 14 to rotate through the transmission belt 18, so that the bidirectional telescopic rod 9 rotates. The second bevel gears 10 symmetrically arranged at both ends thereof rotate. The two second bevel gears 10 drive the corresponding first bevel gears 8 to rotate, so as to drive the two first rotating rods 6 to rotate relatively, and drive the two electric grippers 7 to rotate relatively to adapt to clamping an injection-molded product in a bowl shape.
