Title:
INJECTION MOLDING MACHINE AND CONTROL DEVICE FOR INJECTION MOLDING MACHINE
Document Type and Number:
Japanese Patent JP2023181906
Kind Code:
A
Abstract:
To provide a technology that can easily and appropriately adjust a cold startup prevention period to regulate an operation of a plasticizing member.SOLUTION: An injection molding machine includes: a cylinder that holds a molding material to be injected into a mold; a plasticizing member movably and rotatably provided within the cylinder; a temperature detector that detects a temperature of the cylinder or the mold; and a period setting part configured to set a cold startup prevention period, which is a period of time during which injection of the molding material into the mold is restricted until the temperature of the molding material or the mold temperature rises, based on the temperature detected by the temperature detector. The period setting part stores temperature time data that ties the temperature detected by the temperature detector to time, and adjusts the cold startup prevention period based on the temperature record of the stored temperature time data.SELECTED DRAWING: Figure 6
