Plastic punch forming HSM process for plastic accessory processing

Abstract

The invention discloses a plastic punch forming HSM process for plastic part processing, which comprises the following steps: firstly, wrapping a high-energy polystyrene foam core material with a carbon fiber composite cloth material, then putting the high-energy polystyrene foam core material into a static mold core, then starting a servo motor to drive a movable mold base and a static mold base to be closed, and finally, carrying out injection molding on the high-energy polystyrene foam core material. And then a double-head motor is started to drive an electric heating pipe and a water passing pipe to be alternately inserted into the two mold bases for heating and water passing cooling, the high-energy foaming rubber core material is cooled after being heated, expanded and formed, and finally demolding and taking are conducted. According to the high-energy polystyrene foam core material stamping device, the movable mold base and the static mold base are driven by the arranged liftable mold pressing frame to be closed to stamp a high-energy polystyrene foam core material, then the arranged heating and cooling set is alternately matched with the movable mold base and the static mold base to heat and then cool a sealed space, and during cooling, an electric heating pipe is moved out to avoid being cooled, so that the production efficiency is improved. And the heating device is beneficial to quickly starting and heating the next high-energy foaming rubber core material, saves electric energy and heating time, and has practical value.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a plastic stamping forming HSM process for processing plastic accessories. Background technique [0002] Plastic products are generally made through the traditional nylon blow molding process. However, when some small plastic parts are used in large blow molding machines, they will consume electricity and oil for cooling, which will increase energy consumption. At the same time, after use Waste oil treatment is not conducive to environmental protection. The full name of HSM is thermal self-expanding molding process. It mainly covers the high-energy foam core material with carbon fiber composite cloth, puts it in a sealed space, and reheats to cause the core material to expand into one piece, and the product can be obtained by cooling and demoulding. However, the expanded core material needs to be cooled and shaped in a sealed space before it ca...

AI Technical Summary

Problems solved by technology

However, the expanded core material needs to be cooled and shaped in a sealed space before it can be taken out. Since the loss of the original high-temperature environment will be accelerated during cooling, when the high-energy foam core material is heated again, excessive power consumption is required for heating, which also prolongs the operating time. heating time
