The invention provides a heat insulating structure device, an injection molding machine and a method for controlling heat transfer and the deformation quantity to be consistent. The heat insulating structure device can comprise a base plate. The base plate can be made of a metal material. One or more fluid passageways can be formed in the base plate, so that fluid flows in the base plate through the one or more fluid passageways in a circulating manner. The injection molding machine can comprise two heat insulating structure devices, wherein one heat insulating structure device can be arrangedbetween a fixed side safety bar and a fixed side die portion of the injection molding machine, and the other heat insulating structure device can be arranged between a movable side safety bar and a movable side die portion of the injection molding machine.

AI Technical Summary

Problems solved by technology

[0006] The fiber heat insulation board currently has the following defects: (1) The flatness of the fiber heat insulation board directly affects the parallelism of the locking plate of the machine

The fiber heat insulation board is limited by the material and processing technology, and its flatness is poor; (2) The fiber heat insulation board makes the heat transfer of the locking plate on both sides of the injection molding machine uncontrollable

The temperature of the mold is transmitted to the locking plates on both sides of the injection molding machine through the fiber heat insulation board. Due to the uncontrollable heat transfer process, the temperature on both sides of the machine is inconsistent after heat transfer, resulting in a large difference in the deformation of the locking plates on both sides, resulting in mold clamping The coincidence becomes poor, which in turn affects the surface shape of the lens, the stability of the eccentricity and the service life of the mold
