Three-dimensional modeling apparatus and injection molding apparatus

Abstract

A three-dimensional molding device and an injection molding device, capable of suppressing all melting of a material supplied between a planar spiral and a barrel, are characterized by being provided with: a plasticizing unit having a drive motor, a spiral, a barrel, and a first heater, the drive motor driving the spiral, the barrel, and the first heater; and a first heater that heats the material supplied between the spiral and the barrel, and when at least one of a first condition, a second condition, and a third condition is satisfied, the control unit performs a process that reduces the output of the first heater. Wherein the first condition is that the measured value of a first temperature sensor for measuring the temperature of the spiral piece or the barrel-shaped piece is larger than a first specified value, and the second condition is that the torque value of the driving motor is smaller than a second specified value. The third condition is that the measurement value of a pressure sensor for measuring the pressure of the flow path between the communication hole and the nozzle opening is less than a third predetermined value.

Description

technical field [0001] The invention relates to a three-dimensional modeling device and an injection molding device. Background technique [0002] There is known a three-dimensional modeling device that produces three-dimensional shaped objects by ejecting plasticized modeling materials, laminating them, and solidifying them. [0003] For example, Patent Document 1 describes a plasticizing delivery device that includes: a barrel that opens on one end surface for the material to flow into a passage; and a rotor that has an end surface that is in sliding contact with one end surface of the barrel. ; and a helical groove formed on the end surface of the rotor. The spiral groove is supplied with material from the radially outer end, and the radially inner end communicates with the open end of the material inflow passage of the barrel. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2010-241016 [0005] In the plasticizing delivery device provided with the rotor as d...

AI Technical Summary

Problems solved by technology

If the material is in a molten state in the supply part, the conveying force for conveying the material to the radially inner end cannot be obtained, the ejection will be unstable, and a bridging phenomenon will occur in which no new material is supplied.
