Background

The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool used to make a molded article, which is made up of various parts, with different molds being made up of different parts. The processing of the appearance of the article is realized mainly by changing the physical state of the formed material;

the blank is made into a tool with a specific shape and size under the action of external force. The method is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the molding processing of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by using 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 and combined. And taking out the workpiece when the workpiece is separated, and injecting the blank into the die cavity for forming when the workpiece is closed.

However, the clearance of the inner cavity of the existing multi-cavity section mould is generally smaller, so that the blank and the shunt hole are not well processed, the overall processing difficulty is high, the inner cavity structure is easy to damage in the processing, the cost loss is increased, and the production period is delayed; therefore, the existing requirements are not met, and a die for producing multi-cavity profiles is provided.

Disclosure of Invention

The utility model aims to provide a die for producing multi-cavity sectional materials, which solves the problems that in the prior art, the gap between the inner cavity positions of the conventional multi-cavity sectional material die is generally smaller, so that a blank knife and a shunt hole are not well machined, the whole machining difficulty is high, the inner cavity structure is easily damaged in machining, the cost loss is increased, and the production period is delayed.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a mold for producing a multi-cavity section bar, comprising: a multi-cavity mold body;

further comprises:

the inner cavity male die working belt is arranged at the rear end of the male die cavity, and the inner cavity male die working belt is assembled and arranged with an inner cavity die body of the male die cavity through screws.

Preferably, a female die cavity is arranged on the other side of the inner part of the multi-cavity die body.

Preferably, the outer wall of the female die cavity is provided with a female die welding area.

Preferably, a die welding area is arranged in the die cavity of the male die.

Preferably, a plurality of inner cavity diversion holes are arranged between the male die cavity and the female die cavity.

Compared with the prior art, the utility model has the beneficial effects that:

the working belt of the inner cavity male die is of a rear structure, namely, the position of the inner cavity male die is properly hollowed, the processing position is reserved, the inner cavity flow dividing holes are reserved, and after the hollow knife is processed, the working belt of the inner cavity male die and the inner cavity die body are assembled in a threaded locking mode. Therefore, the difficulty in inner cavity machining can be greatly simplified, and the machining requirements of uniform empty cutters and smooth bridge positions are met.
