Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, and in particular to an in-mold tapping device. Background Technology

[0002] A tapping machine is a machine tool specifically designed for machining internal threads in materials such as metal and plastic. It uses a rotating tap to cut precise threads in a pre-drilled hole. It is widely used in industries such as machinery manufacturing, automobiles, electronics, and hardware. Some mold production processes require machining internal threads on the mold.

[0003] However, in existing equipment, when the tap is machining internal threads on the mold, it needs to be cooled with coolant. However, due to the high speed of the tap rotation and the large centrifugal force, the coolant is easily thrown out, causing coolant splashing and affecting the working environment. Therefore, the mold-in-tap device is proposed. Utility Model Content
