A stationary platen for holding a stationary part of a mold centered to an injection axis is securely connected by tie-rods to a cylinder body integral with a cylinder part of a clamp cylinder which moves a movable part of the mold in a clamp direction, and subjected to a deformation when the mold is clamped, which deformation is made symmetrical with respect to a reference plane including the injection axis by a combination of mechanisms therefor.

Clamping apparatus for precise injection molding

In a method of and apparatus for controlling a plasticizing process of a resin of an in-line screw-type injection molding machine, a position of the screw is continuously detected in accordance with the movement thereof and a control function is determined by a back pressure of the screw which is compensated for by taking into consideration such as resin heating energy and shearing energy, which determine a temperature distribution of a resin to be injected. The operating condition, particularly the number of revolutions and the back pressure of the screw, is controlled on the basis of the screw position so as to make uniform the temperature distribution of the resin.
