AI Technical Summary
Traditional cold presses suffer from insufficient material bonding when processing all-metal, all-wood, or wood-metal composite materials, resulting in unstable quality and low efficiency. Hot presses, on the other hand, have complex structures, consume a lot of energy, and produce uneven temperatures, making it difficult to meet production needs.
The heating device, which uses electricity or natural gas for heating, combined with the optimized structural design of the hot pressing mold, including the guide cavity, circulation pump and telescopic device, ensures uniform and stable heat, and improves processing stability and efficiency through the corrugated arc groove and the concave-convex fit.

[0015] As Figs. 1-2 As shown in a kind of hot-pressing die, including the upper pressure seat 1 and lower pressure seat 2 that are pressed together in longitudinal direction, oil medium is provided with the flow guide cavity 3 for passing in the upper pressure seat 1 or lower pressure seat 2, further include heating device that is heated with electric power or natural gas, the flow guide cavity 3 between heating device and flow, and heating device is further provided with circulating pump that pushes oil medium flow, the upper pressure seat 1 and lower pressure seat 2 are equipped with connecting frame 4, the connecting frame 4 between the upper pressure seat 1 and lower pressure seat 2 is equipped with telescopic device 5, the upper pressure seat 1 and lower pressure seat 2 have wavy arc groove 6, the arc groove 6 center of the upper pressure seat 1 or lower pressure seat 2 is concave arc face, the arc groove 6 center of the upper pressure seat 1 is convex arc face. Through circulating pump, the flow of oil medium is promoted, and flow is conducive to the uniform and rapid emission of heat, to avoid the gathering of heat in a position, so that it will affect material combination effect. Connecting frame 4 facilitates assembly and lifting adjustment, and telescopic device 5 provides power transmission. The design of arc groove 6 can provide multiple processing stations, improve production efficiency, and fully utilize heat. Even if single-station design, then lower pressure seat 2 and upper pressure seat 1 are concave-convex matched, and the center of lower pressure seat 2 is concave arc face, in this case, it is more stable and reliable when adhering, and will not easily shake and deviate. It should be noted that natural gas is a common gas energy in industry, and compared with electric energy, it saves a lot of cost. This kind of small boiler burner heating can meet the demand, the inlet pressure is small, and it is also very safe to use.
[0016] The arc groove 6 of the lower pressing seat 2 is wider than that of the upper pressing seat 1, so that the upper pressing seat 1 is safer and more reliable, and is not easy to deviate or fall during the process, and can be automatically adjusted and corrected along the arc.
