The utility model discloses a radial
drill chambering device for mould manufacturing, which comprises a
workbench, a clamp, a workpiece, a chambering
drill bit, a
drill rod, a plurality of vertical rods, an annular ring, a plurality of ejector rods and a plurality of
pulley assemblies, the workpiece is fixedly connected to the center of the
workbench through the clamp, and the
tail part of the chambering
drill bit is connected to the end part of the drill rod; the vertical rods are connected to the edge of the
workbench, the annular ring is connected to the top ends of the vertical rods, the annular ring is connected with the ejector rod in the radial direction, and the end of the ejector rod is connected with the
pulley assembly. The drill rod penetrates through the center of the annular ring, and the side face of the drill rod is in rolling connection with the
pulley assembly. Compared with the prior art, the supporting device has the advantages that the ejector rods surround the ejector rods, the drill rod is limited to shake in the radial direction, the pulley
assembly is connected with the side face of the drill rod in a rolling mode,
friction force is small, and the supporting effect is good. Due to the fact that the
reamer bit is connected with the drill rod, shaking of the
reamer bit in the radial direction is reduced, and adverse effects caused by shaking are reduced.
