A structurally improved hot press and a hot press forming method thereof

Abstract

The invention relates to the technical field of hot pressing, in particular to a hot press with an improved structure and a hot-press forming method thereof. The hot press with the improved structure comprises a base, wherein the base is fixedly connected with an air exhaust device; an output end of the air exhaust device is connected with an air suction pipeline; an upper surface of the base is provided with a lower module; and an upper module is arranged on the lower module and is connected with a heating device. During use, the air exhaust device is matched with the lower module to adsorb and mold a cutting piece, and the upper module is pressed downwards to be matched with the lower module so as to joint and mold the cutting piece and a joint cutting piece and obtain a finished product; therefore, the production efficiency and the product quality are improved in a mode of replacing stitching by hot pressing. The hot-press forming method comprises the following steps of: cutting into pieces, sleeving the cutting piece, adsorbing for the first time, adsorbing and molding, heating and molding, adsorbing for the second time, putting the joint cutting piece, jointing and molding, and thus obtaining the finished product. In the processing steps, the temperature of the cutting piece is balanced, the pressed cutting piece is fixed and is difficultly moved, the pressure is average,and the rejection rate and the production cost are reduced.

Description

technical field [0001] The invention relates to the technical field of hot pressing, in particular to a structurally improved hot pressing machine and a hot pressing forming method thereof. Background technique [0002] At present, commonly used heat presses include high-frequency and high-frequency heat presses and oil pressure heat presses. Among them, the high-frequency high-frequency heat press is to ionize the pressed pieces instantly through a large current, so that the pressed pieces are welded together. Together, the disadvantage is that the welded pieces are generally firm, and when the pressed piece is large, it cannot be processed, especially when it is subjected to a large current, it is easy to generate sparks, and the operation safety performance is low.

[0002] At present, commonly used heat presses include high-frequency and high-frequency heat presses and oil pressure heat presses. Among them, the high-frequency high-frequency heat press is to ionize the pressed pieces instantly through a large current, so that the pressed pieces are welded together. Together, the disadvantage is that the welded pieces are generally firm, and when the pressed piece is large, it cannot be processed, especially when it is subjected to a large current, it is easy to generate sparks, and the operation safety performance is low.

[0003] As for the hydraulic hot press, the pressing mold is made of special aluminum alloy, so the surface temperature is very uniform, and the temperature rises quickly and stably. The heating pipes of the machine are all made of stainless steel. The parts to be pressed in the hydraulic heat press are evenly heated and the pressure is also balanced, so that the objects to be pressed are welded together after a few seconds at high temperature, but its disadvantage is that it has high power and needs A mold processing machine to ensure that the temperature of the mold is within the working range. Due to the precise control of the hydraulic system, the operator must precisely control the positions of the upper and lower molds and the pressed pieces. The pressure and temperature should not be too high or too high. Too low, only within the working range
