Description

Spiral shaft type lathe for drilling holes in production mold

Technical Field

The invention relates to the field of mold production, in particular to a spiral shaft type lathe for drilling holes in a production mold.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother". The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.

In the process of die production, holes are often punched in the middle of a die, a cylindrical knife is generally adopted in a traditional ground puncher, a cutting edge is flat, punching is not only laborious, but also is easy to bend and deform, and punching efficiency is greatly reduced. The spiral drilling method used then can pack a part of the scraps generated in the drilling process outside the periphery of the hole wall, and most of the scraps are guided to the bottom surface by the spiral blade or are adhered to the spiral screw rod blade to be carried to the bottom surface. The efficiency of drilling has been improved greatly.
