Description

TECHNICAL FIELD

[0001] The utility model belongs to hot press forming field, more specifically, the utility model relates to a kind of hot press forming hydraulic press of U-shaped aluminum plate integrated board. BACKGROUND

[0002] Hot press forming is a simple and common processing method in plastic processing industry. It mainly uses heated processing mold, injects test material, fixes the mold on the heating plate with pressure, controls the melting temperature and time of test material, and then hardens and cools after melting, and the finished product can be taken out. However, the aluminum plates currently used on the market are basically made of cold glue and its matching cold pressing process.

[0003] The patent document with patent number CN211074425U discloses a heat preservation and decoration integrated board pressure forming device, which includes a model table. The left and right sides of the bottom of the model table are symmetrically fixedly connected with support legs. The left and right sides of the model table are symmetrically fixedly connected with support columns. The center of the top of the model table is provided with a cross beam. The center of the bottom of the cross beam is fixedly installed with a hydraulic push rod. The left and right sides of the top of the cross beam are symmetrically provided with first friction-reducing rings. The heat preservation and decoration integrated board pressure forming device disclosed by the utility model forms a buffer area through the cooperation of the supporting sleeve, sliding groove, connecting rod, sliding block and reset spring. It cooperates with the output pressure bearing contraction deformation of the hydraulic push rod to provide further support to the pressing plate with elastic force. When the hydraulic push rod is retracted, it can still support the pressing plate, thereby saving energy, participating in the existing composite wallboard production line, improving the processing efficiency of the composite partition wallboard, and saving energy and production cost.

However, cold pressing process and cold glue will cause pressure solidification on one hand, and the time required for cold pressing process is very long on the other hand. At the same time, cold pressing process mainly consists of two steps of glue spraying and pressing down, which will cause the surface flatness of aluminum plate to cross. UTILITY MODEL CONTENTS
