Abstract: A material delivery device includes: a plasticization unit having a screw and configured to plasticize a material by rotation of the screw to produce a plasticized material; a flow path through which the plasticized material flows; a nozzle having a nozzle opening that communicates with the flow path and delivers the plasticized material to an outside; a cylinder coupled to the flow path; a rod inserted into the cylinder; and a first pressure detection unit configured to detect a pressure of the plasticized material in the flow path via the rod. In a longitudinal direction of the rod, the rod has a rod end surface facing the flow path and a transmission unit at an opposite side of the rod end surface, and transmits a force due to the pressure received at the rod end surface to the first pressure detection unit via the transmission unit.

Abstract: Provided is a controller for an injection molding machine including an injecting member configured to inject a molding material from a cylinder to a mold part, and a drive source configured to cause the injecting member to operate. The controller includes a cold-start prevention part configured to, when a first condition is met, restrict an operation of the injecting member during a cold-start prevention time that is set in advance. When the first condition is met, the cold-start prevention part determines whether or not a second condition, which is different from the first condition, is met to determine whether or not a value shorter than an initial value will be used as the cold-start prevention time.
