Description

Technical Field

[0001] The utility model relates to the technical field of rubber molding hot presses, in particular to a hot press that is convenient for rubber cooling and molding. Background Art

[0002] A hot press heats two pre-fluxed, tinned parts to a temperature high enough to melt and flow the solder. Once solidified, it forms a permanent electrical and mechanical connection between the parts and the solder. Heating rates can be selected to suit different products. The titanium alloy indenter ensures uniform temperature, rapid heating, and exceptional service life. The indenter features a horizontally adjustable design to ensure even pressure across the components. The temperature is digitally controlled for clarity and precision. A digital pressure gauge is available for pre-set pressure ranges.

[0003] In the production process of rubber products, a hot pressing machine is often used to integrally form the rubber products through a heated mold. After the rubber products are produced, the proportions of different rubber ingredients are different, and they are prone to precipitating odors or generating some smoke particles at high temperatures. Long-term inhalation of the smoke particles by workers will pose a health threat. In addition, since the temperature of the rubber products is high after hot forming, it is inconvenient for workers to take them out, thereby reducing production efficiency. The existing hot pressing machine for forming does not have the function of removing odors and the cooling efficiency is not that high, which causes certain inconveniences. Based on this, a hot pressing machine that is convenient for rubber cooling and forming is proposed. Utility Model Content

[0020] The working principle of the above technical solution is as follows: when in use, when the molding machine body 1 drives the pressing plate 2 to move downward, thereby prompting the upper mold plate 17 and the lower mold plate 9 to perform a pressing and forming operation, the air pump 1 4 and the semiconductor refrigerator 8 and the air pump 2 20 are started, and the air pump 1 4 inputs the air flow into the interior of the cooling box 6 through the output pipe 5.

The overall solution facilitates rapid cooling of the molded rubber products, and can adsorb the odor and smoke generated by hot pressing, thereby reducing the odor and smoke in the working environment and protecting the personal health of the operators.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the gas collecting nozzles 24 are evenly distributed in a linear circumferential manner at the bottom of the second rectangular annular tube 16 .

The end of the connecting pipe 19 away from the corrugated telescopic tube 14 is fixed through the base 3 and connected to the top of the inner cavity of the air collecting box 18. The input end of the air pump 20 is connected to the bottom of the activated carbon filter plate 22, and a hollow mesh is provided at the bottom of the activated carbon filter plate 22.
