Description

Technical Field

[0001] The present application relates to the technical field of injection molding machines, and more specifically, to a forming connection mechanism for an injection molding machine frame. Background Art

[0002] As an injection device, an injection molding machine is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. By heating the plastic and applying high pressure to the molten plastic, it is ejected to fill the mold cavity.

[0003] After retrieval, the publication number: CN216267236U discloses an injection molding machine frame connection device, including a mounting base installed on the injection molding machine frame. One end of the mounting base is provided with a mounting arm, and an extrusion barrel is hinged on the mounting arm. One end of the extrusion barrel is provided with a nozzle, and an extrusion shaft is coaxially rotatably connected inside it. By flipping the flip plate upwards, the stop block abuts against the flip plate to isolate the communication between the feed inlet and the extrusion barrel, thereby improving the extrusion efficiency of the extrusion barrel.

[0004] However, in the actual use process, when the thermoplastic plastic enters the extrusion barrel through the feed inlet, the melted thermoplastic plastic is likely to adhere to the surface of the flip plate and the complement position where the flip plate is hinged to the inner wall of the feed inlet. At this time, some of the thermoplastic plastic adhering to the flip plate will solidify due to temperature reduction, resulting in the flip plate being unable to move normally, which needs to be improved.

[0005] To solve the above problems, the present application provides a forming connection mechanism for an injection molding machine frame. Utility Model Content

[0019] In summary, the present application includes the following beneficial technical effects:

[0020] By rotating the rotating rod and contacting the limiting rod, the cover plate is reset and pressed downward to fit the top of the fixed frame. The push-pull plate is used to push the pressing plate to fit the front and rear sides of the cover plate, so that the clamping block is inserted into the clamping groove to fix the position of the cover plate, completing the sealing of the top opening of the fixed frame, and avoiding the phenomenon that part of the thermoplastic plastic adhered to the turning plate solidifies due to temperature reduction, resulting in the inability of the turning plate to move normally, that is, the thermoplastic plastic cannot be continuously injected into the extrusion barrel.
