[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The utility model discloses an injection molding machine for plastic toys of multiple specifications, which is mainly applicable to the scenario where the existing plastic toy injection molding machines are used, each specification of the injection molding machine is only used to realize the injection molding of plastic toys of a single specification, and the specifications of the injection molds placed thereon are constant and cannot be appropriately adjusted according to the specifications of the plastic toys.

[0021] Reference Figure 1-Figure 5 , a plastic toy injection molding machine suitable for multiple specifications, comprising: a base frame 1; a mounting frame 2, arranged on the top of the base frame 1; a top frame 6, arranged on the top of the mounting frame 2; a mold adjustment mechanism 5, arranged on the mounting frame 2, the mold adjustment mechanism 5 includes two adjustment slides 501, and the two adjustment slides 501 are fixedly connected to the opposite sides of the mounting frame 2 near the bottom end, and three sliding blocks 503 are slidably connected to the two adjustment slides 501 at equal distances, and the tops of the two corresponding sliding blocks 503 are fixedly connected to the same external ring 507, and the interiors of the three external rings 507 are fixedly connected to the lower Mold 508, the three lower molds 508 have different specifications, and the mounting frame 2 is located above the two adjusting slide rails 501 and is fixedly connected to the pushing cylinder 502, and the output ends of the two pushing cylinders 502 are fixedly connected to the pushing connecting rods 504, and the bottoms of the two pushing connecting rods 504 are fixedly connected to the integration rods 505, and the integration rods 505 are fixedly connected to the tops of the three sliding blocks 503 in the same row, and the tops of each external ring 507 are annularly distributed with lifting cylinders 509, and the output ends of the multiple lifting cylinders 509 located on the same external ring 507 are fixedly connected to the same upper mold 506.

[0022] In a specific application scenario, before injection molding plastic toys of different specifications, the push cylinder 502 is adjusted to drive the push connecting rod 504 to move, so that the sliding block 503 slides in the adjustment slide rail 501, and the injection mold suitable for the current plastic toy is quickly moved to the bottom of the nozzle 7. There is no need to constantly replace the injection molding machine according to the specifications of the plastic toys, thereby improving the practical value of the injection molding machine.

[0023] Reference Figure 1 、 Figure 4 and Figure 5 In a preferred embodiment, a lifting hole is opened on the top of the top frame 6 at the center position, and the top of the top frame 6 at both ends of the lifting hole are fixedly connected to a hydraulic cylinder 3, and the output ends of the two hydraulic cylinders 3 are fixedly connected to the same lifting external plate 8.

[0024] Reference Figure 4 and Figure 5 In a preferred embodiment, the inner side wall of the lifting external plate 8 is fixedly connected to the injection cylinder 4, and two telescopic connecting rods 9 are symmetrically distributed on the top of the lifting external plate 8, and the top ends of the two telescopic connecting rods 9 are fixedly connected to the bottom of the top frame 6.

[0025] Reference Figure 4 In a preferred embodiment, a feed hole is opened at the top of the injection barrel 4, and an inlet pipe 11 is fixedly connected to the inside of the feed hole, and a flow valve 10 is connected to the outer wall of the inlet pipe 11 through a flange. A nozzle 7 is fixedly connected to the bottom of the injection barrel 4, and the nozzle 7 is located directly above one of the upper molds 506.

[0026] Specifically, when performing injection molding of plastic toys of different specifications, after adjusting the injection mold, the opening and closing time of the flow valve 10 is adjusted according to the amount of molten liquid required for injection molding, thereby ensuring that the amount of liquid entering the syringe 4 is the same as the amount of liquid required for injection molding.

[0027] Reference Figure 5 In a preferred embodiment, two hydraulic cylinders 2 13 are symmetrically distributed on the top of the injection barrel 4, and the output ends of the two hydraulic cylinders 2 13 are fixedly connected to the same annular scraper 14, which is in contact with the inner wall of the injection barrel 4. There are two mounting holes on the annular scraper 14, and the inside of the two mounting holes is fixedly connected to the vibrating rod 12.

[0028] It should be noted that after the molten liquid is introduced into the upper mold 506 and the lower mold 508 through the nozzle 7, the flow valve 10 is closed, and the hydraulic cylinder 2 13 is adjusted to drive the annular scraper 14 to move downward. At the same time, the vibrating rod 12 is turned on, and the annular scraper 14 scrapes off the liquid attached to the inner wall of the injection barrel 4. The vibrating rod 12 makes the annular scraper 14 in a vibrating state, and the scraped liquid will not adhere to the annular scraper 14, thereby improving the accuracy of liquid feeding.

[0029] Working principle: When in use, the upper mold 506 and the lower mold 508 are adjusted according to the specifications of the current injection molded toy, and the push cylinder 502 is adjusted to drive the push connecting rod 504 to move, so that the sliding block 503 slides in the adjustment slide rail 501, and the injection mold suitable for the current plastic toy is quickly moved to the bottom of the nozzle 7, and then the hydraulic cylinder 1 3 is adjusted to drive the nozzle 7 under the injection barrel 4 to dock with the injection hole on the upper mold 506. After the docking is completed, the opening time of the flow valve 10 is adjusted, and the liquid is introduced into the injection barrel 4 through the introduction pipe 11 and introduced into the space between the upper mold 506 and the lower mold 508 through the nozzle 7. When the flow valve 10 is closed, the hydraulic cylinder 2 13 is adjusted to drive the annular scraper 14 to move downward. At the same time, the vibrating rod 12 is turned on, and the annular scraper 14 scrapes off the liquid attached to the inner wall of the injection barrel 4. The vibrating rod 12 makes the annular scraper 14 vibrate, so that the scraped liquid will not adhere to the annular scraper 14. After all the liquid is introduced into the interior of the upper mold 506 and the lower mold 508, molding begins.

[0030] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
