Description

Technical Field

[0001] The utility model relates to an automatic sleeve injection device for an injection double-head manipulator. Background Art

[0002] In the production process of plastic products, the sleeve injection molding process is often used. The existing sleeve injection molding process mainly completes the products taken and placed by manual labor. The efficiency of manual taking and placing products is low, and safety accidents are prone to occur. In addition, the labor cost is getting higher and higher, which is not conducive to reducing the product manufacturing cost.

[0003] In the prior art, manipulators are also used to take and place the injection-molded products. However, due to the complex structure of the manipulator, when the position between the manipulator and the product to be picked up is not aligned, the manipulator needs to waste a lot of time to adjust the position, which is extremely inconvenient to use and not conducive to improving the efficiency of the manipulator picking up products. In addition, the taken-out injection-molded parts are connected by sprues. Before the injection-molded parts need to be processed in the next step, the sprues of the injection-molded parts need to be sheared manually or by manual operation equipment, which not only wastes time, but also results in low quality of the injection-molded parts due to uneven cutting parts of the sprues. After the sprues are cut, the scattered injection-molded parts need to be manually arranged on the mold before the next processing step can be carried out. Summary of the Invention

[0025] A hydraulic cylinder hinge seat 11 is sleeved on the upper section of the bracket 1. Specifically, it is used to assemble the hydraulic cylinder 2.

[0026] A bracket hinge shaft 21 is arranged in the middle part of the rotating frame 2. Specifically, it facilitates the rotation of the rotating frame 2 at the lower end of the bracket 1;

[0027] A cylinder hinge shaft 22 is arranged on the back of the rotating frame 2. Specifically, it can be hinged to the output end of the hydraulic cylinder 2.

[0028] A fixed seat 23 is arranged on the front of the rotating frame 2. Specifically, a pressing plate 41 can be fixedly installed through bolts.

[0029] It should be further noted that by driving the rotating frame 2 with the hydraulic cylinder 2, it can be rotated, thereby adjusting the angle of the sleeve injection assembly 4, enabling the whole sleeve injection assembly 4 to face the injection molding machine for gate cutting and material taking, or adjusting the angle of the sleeve injection assembly 4 to face downwards to transfer the injection molded part to the mold of the next device.

[0030] The sleeve injection assembly 4 includes a pressing plate 41 fixedly installed on the rotating frame 2 through bolts, spring buffer members 42 fixedly installed at the four corners of the pressing plate 41 through bolts, blowing mechanisms 43 equidistantly arranged on the pressing plate 41, and a top plate 44 assembled with the spring buffer members 42 and cooperating with the pressing plate 41 to sleeve the injection molded part, and a stamping die 45 integrally formed on the front of the top plate 44.

[0031] Buffer member mounting holes 411 are arranged at the positions of the pressing plate 41 corresponding to the installation of the spring buffer members 42, and pipe holes 412 for cooperating with the installation of the adsorption mechanism 42 are equidistantly opened on the pressing plate 41.

[0032] The spring buffer 42 includes a base 421 with a threaded hole, a sleeve 422 welded to the central part of the base 421, a connecting column 423 passing through the sleeve 422 and welded and fixed to the base 421 with a threaded hole at the end, a pressure relief spring 424 sleeved on the connecting column 423, and a stud 425 screwed into the connecting column 423 to fix the top plate 44. Specifically, the sleeve 422 passes through the buffer mounting hole 411, the base 421 abuts against the pressing plate 41 and is fixedly installed by bolts. The pressure relief spring 424 sleeved on the connecting column 423 contacts the top plate 44, and then the stud 425 passes through the top plate 44 and is screwed into the connecting column 423, so that the top plate 44 can move according to the length of the stud 425, and is supported and fixed by the pressure relief spring 424, and is limited by the connecting column 423.

[0033] The blowing mechanism 43 includes a mounting seat 431 fixed to the pressing plate 41 by bolts, a rigid air pipe 432 fixed to the mounting seat 431 by screws, and a flexible air pipe 433 connected and communicated with the rigid air pipe 432. Specifically, the tail end of the rigid air pipe 432 passes through the pipe hole 412 and is then connected and communicated with the flexible air pipe 433.

[0034] The four corners of the top plate 44 are provided with stud assembly holes 441. Specifically, the stud 425 passes through the stud assembly holes 441 and is screwed into the connecting column 423, so that the top plate 44 and the pressing plate 41 can be assembled cooperatively.

[0035] A nozzle assembly hole 451 is provided in the central part of the stamping die 45, a cutting groove 452 is provided at the water inlet of the stamping die 45, and a cutter 453 is integrally formed in the cutting groove 452. Specifically, the robotic arm in the gantry drives the pressing plate 41 to make the top plate 44 contact the molding die of the injection molding machine, and then drives the pressing plate 41 to press the top plate 44 forward again, so that the cutter 453 inside the stamping die 45 cuts off the water inlet, and at the same time the injection molded part is embedded in the stamping die 45, so as to transfer the injection molded part. When the injection molded part is transferred to the next device, the rigid air pipe 432 in the blowing mechanism 43 passes through the nozzle assembly hole 451, and then blows the injection molded part away from the stamping die 45 by instantaneously jetting air, so that it falls into the die of the next device.
