摘要： An injection molding machine includes a cylinder configured to heat a molding material including bioplastics and a rotating member provided in the cylinder. The molding material is fed from upstream to downstream along a helical groove formed in the rotating member by the rotating member being rotated. The rotating member includes a first region and a second region downstream of the first region. The first region and the second region are different in shape, dimensions, or both. A retention time of the molding material in the first region is longer than in a case in which the first region has the same shape and the same dimensions as in the second region.

摘要： A management device is for an injection molding machine including a cylinder divided into zones from upstream to downstream along a direction in which a molding material is fed, a temperature adjuster provided in each of the zones, and a temperature detector configured to detect an actual temperature of each of the zones. The management device includes processing circuitry configured to detect abnormal heat generation due to shearing of the molding material based on the actual temperature of a predetermined zone of the zones excluding a most upstream zone and a most downstream zone.

摘要： A controller is for an injection molding machine including an injecting member configured to push a molding material in a forward direction, the molding material containing a bioplastic; and an injection drive source configured to cause the injecting member to travel forward or backward. The controller is configured to perform filling in which a forward travel speed of the injecting member is controlled so that an actual value of a pressure applied from the injecting member to the molding material does not exceed an upper limit of the pressure. In at least a part of the filling, a value of from 550 mm/s through 700 mm/s is settable as a set value of the forward travel speed of the injecting member, and a value of 200 MPa or higher is settable as the upper limit of the pressure.

摘要： A management device is for an injection molding machine configured to repeatedly perform a shot that is a series of operations for producing a molded product in a mold part. The management device includes processing circuitry configured to: repeatedly obtain a numerical value of a physical quantity of at least an object that is withdrawn from an interior of the mold part to an exterior thereof or that is fed from the exterior of the mold part to the interior thereof, the numerical value of the physical quantity being measured externally of the mold part; and record the numerical value in association with identification data of the shot.
