Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing and processing, specifically, it relates to a multi-layer composite material hot pressing composite device. Background Technology

[0002] The multilayer composite material hot-pressing composite device is an industrial equipment that uses high temperature and high pressure to bond and solidify different material layers into a single structure. Its core is to achieve molecular-level fusion of material interfaces by precisely controlling temperature, pressure and time parameters.

[0003] The prior art discloses a hot pressing device for composite materials (CN202223000944.8), including a base, a lower pressure plate, and an upper pressure plate. The lower pressure plate is fixedly connected to the base, and the upper pressure plate is provided with a corresponding clamping assembly for driving the upper pressure plate to press down. Both the lower and upper pressure plates have heating chambers for accommodating heat-conducting media. A guide rod is fixedly provided on the base, and an installation frame is fixedly provided at the upper end of the guide rod. The clamping assembly is a hydraulic cylinder, and the housing of the hydraulic cylinder is detachably connected to the installation frame. The output shaft of the hydraulic cylinder is detachably connected to the upper pressure plate. A guide tube matching the guide rod is fixedly provided on the upper pressure plate, and the guide rod is installed inside the guide tube.

[0004] The existing guide tube plays a guiding role in the pressing process of the upper pressure plate, making the pressing process of the upper pressure plate more stable. The pressing of the upper pressure plate heat-presses the composite material. When the composite material is thick, it is easy for the material to shift before pressing by manual stacking, which will cause the material to tilt and become misaligned, affecting the quality of the composite material after pressing.

[0005] In view of this, this utility model is proposed. Utility Model Content

The two-sided alignment structure is set on both sides of the lower pressure plate. Above the lower pressure plate, there are two push plates that push the material to align when the upper pressure plate rises and move away from the upper pressure plate when the upper pressure plate falls.

[0007] In a preferred embodiment of this utility model, the two-sided pushing structure further includes side covers, rotating rods, a first sector gear, and a second sector gear. A side cover is provided on each side of the lower pressure plate, and the bottom surfaces of the two side covers are fixedly connected to the top surface of the base.

[0012] Compared with the prior art, the present invention has the following advantages: 1. Four second push rods drive four first push rods, which in turn drive four connecting plates. Two push plates are pushed forward to align the two sides of the composite material, preventing the material edges from becoming skewed during hot pressing and affecting the composite quality.

[0013] 2. With the two racks pointing downwards and the two gears rotating in opposite directions, the two push plates retract and move away from the material and the lower pressure plate. The two push plates are not limited by height and can push materials of different thicknesses together.
