The clamping device includes a pair of clamping members arranged in positions to clamp a rib (target portion to be clamped) of a workpiece and having contact surfaces to make contact with the rib; supports configured to support each of the pair of clamping members so as to be able to advance and retreat along a prescribed advancing/retreating direction relative to the rib, and to operate each of the pair of clamping members so as to clamp the rib when advancing; guiding units configured to make each of the pair of clamping members movable in a prescribed positioning direction due to a reaction force occurring when the pair of clamping members clamp the rib; and coil springs (biasing members) configured to elastically bias the pair of clamping members in a direction opposite the positioning direction, thereby capable of positioning the workpiece with high precision without damaging the workpiece.

Clamping device

The present invention pertains to an injection molding mold that can extrude the entirety of a workpiece from a cavity even when the cavity is enlarged so as to extend further than the outer side of an ejector plate. The injection molding mold may include a mold member having a cavity formed on the front side, a mold frame supporting the mold member from the back side, an ejector plate provided in the space within the mold frame so as to ascend and descend freely therein, a first workpiece extrusion means for extruding the workpiece above the ejector plate, and a second workpiece extrusion means for operating in conjunction with the first workpiece extrusion means and extruding the workpiece formed in the cavity in an area that is further to an outer side than the ejector plate.

Injection molding mold

An injection molding machine nozzle capable of suppressing stringiness caused by unsolidified resin in the case where a mold is released in a short time and reducing a cycle time, is provided. An injection molding machine nozzle () includes a nozzle hole to eject molten resin from a hot runner (). The injection molding machine nozzle () includes a nozzle tip () made of a material having higher heat conductivity than that of the hot runner () and including a nozzle hole (B) communicating with a most downstream side of a resin flow path of the hot runner (). The nozzle tip () is joined to the hot runner () through a heat insulation member ().
