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.

The drift is the metal part of installing on stamping die, is applied to the direct contact with the material, makes the material take place deformation, cuts the material, and the mould drift generally adopts high-speed steel and tungsten steel etc. as the material, has high-speed steel drift and tungsten steel drift etc. the drift is cooperating the drift pole, and the drift nut is dashed female the use together, generally is used for iron tower factory to punch a hole the usage, HL blade professional processing: the punch, the punch nut, the punch rod and the punch nut in the numerical control iron tower factory have been developed from the production of a common vehicle to the numerical control production for decades. When need use accurate drift to carry out further processing to aluminium system mould when making aluminium system mould, when the tradition used the drift, can lead to the drift to generate heat because long-time the use to easily cause the loss to aluminium system mould.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a cooling structure of a die punch, which can effectively solve the problem that when an aluminum die is manufactured, an accurate punch needs to be used for further processing of the aluminum die, and when the punch is used in the traditional process, the punch is heated for a long time, so that the aluminum die is easy to be worn.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides a cooling structure of mould drift, includes the drift, the feed liquor hole has been seted up in the left side of drift inner wall, the below in feed liquor hole be provided with the cooling ring through pipe connection, the downside of cooling ring be provided with the cooling hole, the below of cooling hole be provided with the coolant liquid buffer.

Preferably, through holes are formed around the cooling holes.

Preferably, the surface of the cooling liquid buffer zone is provided with a buffer ring.

Preferably, the surface of the buffer ring is provided with buffer holes.

Preferably, the cooling holes are arranged in a plurality, and the liquid inlet holes are arranged in two.

Preferably, the section of the cooling liquid buffer zone is V-shaped.

Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a cooling structure of mould drift, the coolant liquid gets into the cooling ring from the feed liquor hole, then the coolant liquid flows into each cooling hole through the cooling ring, then flows to the coolant liquid buffer zone from the cooling hole, realizes the buffering of coolant liquid flow to the drift head, then the coolant liquid flows to the drift head and realizes the cooling effect to the drift to can further play the effect of buffering, protect the mould drift, improve the mould from the life of head.
