Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a material changing mechanism applied to injection molding machines. Background Art

[0002] An injection molding machine is a device that squeezes thermoplastics or thermosetting plastics into a molding mold to prepare plastic products. A current injection molding machine material changing device includes a barrel and a base, and a discharge port and a material changing port are provided on the base, and the discharge port and the material changing port are arranged at intervals. When changing materials, for example, when one type of plastic granules (commonly known as plastic rice) is replaced with another type of plastic granules, the original plastic granules in the barrel need to be discharged from the material changing port. However, to move the barrel from the discharge port to the material changing port, it is necessary to move the barrel manually, which requires several operators to overcome very large friction to push it. Each operator needs to exert a lot of effort to achieve the back and forth movement of the barrel, and it takes a long time.

[0003] In order to facilitate manual material replacement and reduce labor intensity, the prior art has proposed a Chinese authorized utility model with publication number CN215661470U, in which a slide rail and a slider (or a roller / bearing related structure) are provided between the base and the bottom plate to reduce sliding friction and improve efficiency.

[0004] However, with the reduction of frictional force, the problem of misalignment between the barrel and the discharge port / feed port is easy to occur, making it difficult to ensure stable docking between the barrel and the discharge port / feed port.

[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0027] See also Figure 1-4 In an embodiment of the utility model, a material changing mechanism applied to an injection molding machine comprises a base 1 and a bottom plate 2 movably connected to the base 1, the base 1 has a material discharge port 3 and a material changing port 4 arranged at intervals, and the bottom plate 2 has a material feed port 5 corresponding to the barrel;

[0028] A limiting clamp 6 is fixedly provided on the side of the bottom plate 2, and the limiting clamp 6 is clamped and matched with the base 1, wherein the limiting clamp 6 is connected with a connector 7 and is provided with a through hole 8 matching the connector 7, and the side of the base 1 is provided with a first plug hole 9 corresponding to the position of the discharge port 3, a second plug hole 10 corresponding to the position of the material change port 4, and a third plug hole 11 located between the first plug hole 9 and the second plug hole 10, and the connector 7 is plugged and matched with the first plug hole 9 or the second plug hole 10 or the third plug hole 11 through the through hole 8.

[0029] In the technical solution of the utility model, the sliding of the bottom plate 2 and the base 1 can be achieved through the slide rails and sliders, or the roller / bearing related structures, so as to reduce the sliding friction and improve the efficiency; by setting the limiting clamps 6 at two ends of the bottom plate 2, the bottom plate 2 can be clamped on the base 1 through the limiting clamps 6 on both sides, effectively increasing the connection between the bottom plate 2 and the base 1, thereby effectively ensuring that the docking of the feed port 5 and the discharge port 3 or the material change port 4 can always be in the same straight line, and by providing a first plug hole 9 corresponding to the position of the discharge port 3, a second plug hole 10 corresponding to the position of the material change port 4, and a third plug hole 11 located between the first plug hole 9 and the second plug hole 10 on one side of the base 1, combined with the setting of the plug-in component 7 on the limiting clamp 6, the plug-in cooperation of the plug-in component 7 with the first plug hole 9 or the second plug hole 10 or the third plug hole 11, the docking of the feed port 5 and the discharge port 3 or the material change port 4 can be kept stable, and the bottom plate 2 can be located between the discharge port 3 and the material change port 4 of the base 1, which is convenient for the maintenance of both.
