Abstract

The invention relates to an injection molding machine and method. The injection molding machine, formed by injecting melting resin in a die, comprises a first suction part and a second suction part which, respectively arranged at two sides of the die, are used for inhaling the gas inside the die. The invention also discloses an injection molding method, comprising the steps of injecting the die with melting resin and inhaling the gas inside the die from two sides of the die. The injection molding machine and method can precisely form thin sheet material and make the sheet material via one-time injection. Therefore, no drilling, cutting, and other sheet material processing operation are required. The injection molding machine also can improve the flow ratio of the die.

Description

technical field [0001] The present invention relates to an injection molding machine and an injection molding method (APPRATUS FOR INJECTION MOLDING AND METHOD OF INJECTION MOLDING), in particular to an injection molding machine and an injection molding method for plate forming. Background technique [0002] Generally speaking, in order to process plastic material plates used in household appliances, injection molding (injection molding) method can be used, or cutting process using NC (numerical control) / CNC (computer numerical control) machine. [0003] In the conventional injection molding method, due to the limitation of the mold flow ratio (L / T, L: the flow distance of the plastic, T: the thickness of the injection molded object) according to the flow resistance of the plastic injected into the mold, molds with a certain length or more In the case of thin-meat sheets, there will be problems such as poor molding and generation of weld lines due to plastic not being inject...
