Abstract
An injection molding machine is provided with a nozzle touch mechanism configured to press a nozzle attached to an injection device against a mold, a drive unit configured to move the injection device, a drive compression member connected to the drive unit, an injection compression member connected to the injection device, at least one resilient member interposed preloaded between the drive compression member and the injection compression member, and at least one strain sensor mounted on the drive compression member.
Claims8
An injection molding machine, comprising:
- a nozzle;
- an injection device;
- a drive unit configured to move the injection device;
- a nozzle touch mechanism configured to press the nozzle attached to the injection device against a mold, the nozzle touch mechanism comprising:
- a drive compression member connected to the drive unit;
- an injection compression member connected to the injection device;
- at least one resilient member interposed between the drive compression member and the injection compression member;
- at least one strain sensor mounted on the drive compression member;
- and
- a processor configured to calculate a nozzle touch force based on an output value or output values output from the at least one strain sensor,
- wherein the at least one resilient member comprises a plurality of resilient members, and
- wherein the at least one strain sensor is mounted on the drive compression member between the plurality of resilient members.
