Description

Technical Field

[0001] The utility model relates to the technical field of glass hot bending machines, in particular to a bottom mold returning device of a glass hot bending machine. Background Art

[0002] The glass hot bending machine or plexiglass bending machine is actually called plastic plate hot bending machine. It is a processing equipment for acrylic, plexiglass, PC, PVC, SBS, and other plastic plates. When the glass hot bending machine is working, the mold at the bottom of the glass hot bending machine needs to be moved back to its original position through the mold return device.

[0003] For example, a bottom mold return device of a 3D glass hot bending machine with an authorization announcement number of CN218202534U includes a frame, a cooling mechanism and a mold return mechanism, wherein the cooling mechanism includes multiple lower cooling plates, and the multiple lower cooling plates are fixed on the frame; although the above document can realize the sequential transfer of multiple molds to the second mold shifting assembly, the second mold shifting assembly transfers the mold from one end of the frame to the other end of the frame, thereby realizing the transfer of the mold; but when in use, when the mold return device drives the bottom mold of the glass hot bending machine to move, by placing the mold on the platform, the mold on the platform is driven to move. When the mold stops moving, the mold is affected by inertia at this time, and the mold can move back to the previous distance, resulting in the mold being unable to move to the original position, thereby reducing the use effect of the mold return device; at the same time, in the process of the mold return device driving the bottom mold of the glass hot bending machine to move, the mold is driven to move only by a platform. After a mold moves, the platform needs to be moved to the initial position, and then the next mold is placed on the platform to move it to its original position, thereby reducing the working efficiency of the mold return device.
