Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a multi-axis parallel rapid prototyping machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] At present, some existing injection molding machines usually need to wait for cooling after injection molding before molding, but the cooling speed is slow, resulting in reduced equipment working efficiency. Secondly, some injection molding machines usually cause incomplete material molding due to material breaking, which affects the output efficiency of the equipment and reduces the practicality of the equipment.

In the above scheme, the cooling component is set to quickly cool and mold the object without waiting too much time, thereby achieving the purpose of saving production time and further achieving the effect of improving the working efficiency of the equipment; the constant temperature component is set to keep the material in a molten state, so that the raw material will not be cooled into blocks during transportation, thereby achieving the purpose of not breaking the material, ensuring the quality of the object molding, and thus improving the practicality of the overall device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] Embodiment 1: A multi-axis parallel rapid prototyping machine, comprising an operating table 1 and a column 2, the column 2 is fixedly mounted on the upper surface of the operating table 1, a fixing plate 201 is fixedly mounted on the upper surface of the column 2, a buffer mechanism is arranged on the bottom surface of the operating table 1, and a molding mechanism is arranged on the upper surface of the operating table 1;

[0027] The buffer mechanism includes a damping rod 3, a fixed base 301, a slide groove 304, a connecting block 305, a rotating shaft groove 306, a rotating shaft 307, an oblique connecting plate 308, a slider 309 and a compression spring 310.

[0028] A support column 302 is fixedly installed on the bottom surface of the fixed base 301, and a support base 303 is fixedly installed on the bottom surface of the support column 302. The support columns 302 are symmetrically distributed at the four corners of the bottom surface of the fixed base 301, and the slide grooves 304 are symmetrically distributed on the upper surface of the fixed base 301. One end of the compression spring 310 is fixedly connected to the side of the slider 309, and the side of one end of the slider 309 is fixedly connected to the lower surface of the oblique connecting plate 308. By arranging a buffer mechanism at the bottom of the operating table 1, vibration generated during extrusion injection molding operation will cause the damping rod 3 to reciprocate up and down, and the oblique connecting plate 308 pushes the slider 309 to slide on the inner wall of the slide groove 304 to squeeze the compression spring 310, so that the compression spring 310 generates a restoring elastic force to buffer the vibration and make the injection molding stable.

[0029] The rapid prototyping machine is working for extrusion injection molding. The vibration generated during the extrusion injection molding will affect the injection molding effect. At this time, the vibration will cause the damping rod 3 to reciprocate up and down on the bottom surface of the operating table 1.

The feeding pipe 403 is symmetrically distributed. On both sides of the connecting seat 402, baffles 407 are distributed in sequence at equal intervals on the upper surface of the operating table 1.

The curvature of the inner wall of the arc clamp 411 is the same as the curvature of the outer surface of the placement seat 405. By fixing multiple baffles 407 in sequence at equal intervals on the upper surface of the operating table 1 and fixing the cylinder 408 on the side of the baffle 407, the telescopic shaft 409 is installed at the output end of the cylinder 408 to realize multi-axis linkage to fix and clamp the mold placed in the molding groove 406 to maintain stable molding.

[0032] The injection molding raw material is transported to the connecting seat 402 through the feeding pipe 403, and the molding injection mold is placed on the inner bottom surface of the molding groove 406. The cylinder 408 is started so that the cylinder 408 pushes the telescopic shaft 409 to move to one side of the molding mold so that the inner wall of the arc clamping plate 411 contacts the outer surface of the molding mold and fixes it. The hydraulic cylinder 4 is started, and the hydraulic cylinder 4 pushes the lifting column 401 to descend, driving the connecting seat 402 and the injection molding round seat 404 to descend.
