Abstract

The invention is about a program controlling method of the Rotational molding machine. It uses an industrial controlling computer and a programming controller. A set of rotational molding machine software is installed in the computer. The controlling command is input by the standard keyboard and the windows; at the same time, the computer collects the detecting value and transfer the command to the controller input end after computing the value and the output end sends out the controlling signal. The invention can produce the rotational molding product in a large batch.

Description

technical field [0001] The invention relates to a program control method of a rotomolding machine, and the rotomolding machine belongs to a plastic processing machine. Background technique [0002] Rotational molding machine is a commonly used plastic product forming machine, especially for large closed or semi-closed products that do not require high precision and are often formed by this method. It generally adds quantitative rotary powder into the mold cavity through the principle of spherical trajectory thermoplastic molding, heats the mold through the heat source, and at the same time makes the heated mold rotate along the spherical trajectory, the plastic is melted and plasticized, attached to the entire surface of the mold cavity, cooled and shaped, and finally Open the mold and take out the product. [0003] The rotomolding machine generally consists of a heating chamber and a heating system that provides heat to it, a rotomolding mold rotation system, a working fra...
