Description

Hot press structure

The present invention relates to a hot press structure, and more particularly to a method for compressing two hot-pressed fabrics into a predetermined shape in a predetermined region thereof by thermocompression bonding, and the foregoing is further formed in a predetermined shape region. The combination of multiple hot stamping marks replaces the seamless sewing machine with traditional sewing, Thermoplastic Polyurethane (TPU) and hot press structure of various materials.

According to the conventional heat press structure, which can combine the two hot-pressed fabrics by hot pressing, the utility model comprises: a machine base provided with a lower mold base, and a upper part of the lower mold base is provided with a hydraulic cylinder for driving up and down a mold base; two sets of template devices are respectively disposed on opposite inner sides of the upper and lower die holders, and the template device comprises: an outer template, a heating plate and a heat insulation plate are sequentially stacked; when the two sets of template devices are respectively grouped After being disposed on the upper and lower mold bases, the outer template is located on the opposite inner side surface, and the template is used for connecting the hot pressing mold outside the upper mold base, thereby performing hot pressing forming on the hot pressed fabric; There is a set of heaters, wherein the heater comprises a plurality of heating elements evenly distributed on the heating plate, each set of heaters is electrically connected to a temperature control button, and the temperature control button of the corresponding group is set to control the heating temperature; After heating, the thermal energy can be indirectly transmitted to the outer template and the hot pressing mold.

When the two hot-pressed fabrics are to be subjected to the hot-pressing processing, the workpiece to be processed is first laid on the outer template of the template device of the lower mold base, and the lower mold base protrudes from the front end of the machine in a natural standby state. After the lower mold base is pushed into the opposite position with the upper mold base, the hydraulic cylinder is started to drive the upper mold base to descend, and the hot pressing mold attached to the template device of the upper mold base contacts the workpiece to transfer heat energy for several seconds. After that, the hot-pressed texture of the predetermined shape can be hot pressed at the predetermined part of the workpiece to be processed, and then the upper mold base is returned to the original state, and the lower mold base can be pulled out to take out the processed piece, and then the above steps can be repeated to complete another Hot pressing of the workpiece.

When the above-mentioned hot press structure is executed, there is a disadvantage that when the heating plate is heated to a preset temperature by a single heater, the required warm-up time is long, and there is no specific one that can be used more frequently. The area is set for different heating temperatures.

When the hot pressing die attached to the upper mold base pressurizes the two hot press fabrics to perform heat transfer, the temperature of the hot press die introduced into the hot press fabric is absorbed by the hot press fabric, and the temperature of the end is lowered. The temperature of the outer template of the template device disposed in the upper mold base corresponding to the pressing portion of the hot pressing mold is also absorbed by the hot pressing fabric, and the hot pressing mold and the outer template are partially lowered in temperature. The corresponding heating plate indirectly transmits heat energy indirectly, and after the temperature rises to the preset temperature value, the pressurization cooperation is performed again, so that the two hot-pressed fabrics to be processed can achieve the heat-pressable bonding performance; The temperature of the piece, or the template position outside the lower die holder, may not reach the preset temperature value in the above-mentioned independent area, or the heating temperature is not uniform, which will result in the workpiece not being able to achieve the purpose of thermal bonding or the local area being heat-pressed. Will produce a phenomenon of thermal bonding is not true.

According to the above, when the hot press continuously performs hot pressing and bonding work on the workpiece, since the heating plate performs the heating operation of the entire area only with a single heater, when the hot pressing mold and the corresponding outer template are located below the outer template When the temperature continues to decrease, the aforementioned independent area may not be able to quickly receive the heat conduction from the heating plate, so that it fails to reach the predetermined temperature value in a short time, forcing the operation to be interrupted during the hot pressing process, waiting for the foregoing After the temperature rises to the preset value, the machining operation can be continued, resulting in limited productivity. During the period, the operator often does not pay attention to the temperature of the hot pressing die and the outer die plate. When the preset value is not reached, the heat is performed. The pressing operation causes disadvantages such as a high pressing failure rate of the workpiece.
