Description

Technical Field

[0001] This utility model relates to the field of rotational molding machines, and in particular to a dual-station quick mold changing rotational molding machine. Background Technology

[0002] Rotational molding, also known as rotational molding, is a method of hollow plastic molding. The process involves first adding plastic raw material into a mold, then continuously rotating and heating the mold along two perpendicular axes. Under the influence of gravity and heat, the plastic raw material gradually and evenly coats, melts, and adheres to the entire surface of the mold cavity, forming the desired shape. The final product is then cooled and solidified.

[0003] Chinese patent CN206644221U discloses a rotational molding machine, including a base with a mounting frame on the base. The two sides of the mounting frame are rotatably mounted on the base via rotating shafts. A rotating frame is mounted on the mounting frame, and a rotational molding mold is located in the middle of the rotating frame. Front roller assemblies and rear roller assemblies are located at both ends of the mounting frame, and the front roller assemblies and rear roller assemblies are located between a first drive shaft and a second drive shaft. However, the existing device still has some shortcomings. When using a rotational molding machine, the material to be injected is generally poured into the injection barrel and rotated to distribute it evenly and fuse it through high temperature. However, rotating the injection barrel takes a period of time to ensure that the material is evenly distributed in the injection barrel, resulting in wasted processing time. Therefore, we propose a dual-station quick mold change rotational molding machine to solve the above problems. Utility Model Content

[0007] In a further embodiment, the support assembly includes a support frame located on the upper surface of the support plate. A first bearing is embedded in the upper surface of the support frame. A first connecting rod is installed on the inner ring of the first bearing.

[0008] In a further embodiment, both of the rotating components include mounting slots, both of the mounting slots are located on the upper surface of the rotating block, the inner walls of both mounting slots are inlaid with second bearings, the inner rings of both second bearings are fitted with second connecting rods, and the ends of the two second connecting rods that are close to each other are fitted with second drive motors.

[0009] In a further embodiment, both propulsion components include a support cylinder, each of the two support cylinders being located at one end of the second connecting rod. An electric push rod is installed inside each of the two support cylinders, and a push rod is installed at the output end of each of the two electric push rods.

[0010] In a further embodiment, both injection molding components include mounting brackets, each mounted bracket being located at one end of a push rod. A third bearing is embedded in the outer surface of each mounting bracket, and a third connecting rod is mounted on the inner ring of each of the two third bearings. A third drive motor is mounted on one end of each of the two third connecting rods, and an injection molding cylinder is mounted on the other end of each of the two third connecting rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a dual-station quick mold changing rotational molding machine. By installing two injection molding components at both ends of the device and cooperating with two sets of rotating components, the two injection molding components can be driven to rotate.
