This mould production efficiency is high, save time, and the material resources of using manpower sparingly, and impact block's the no burr in surface reduce epilogue manufacturing procedure, and the simultaneous processing precision obtains improving, and accommodation is wide.

Description

Impact block mold

technical field

The utility model relates to a mold, in particular to an impact block mold.

Background technique

The impact block is a component used for electric tools. The existing production methods of the impact block require secondary processing after forming to reduce the burrs on the surface of the impact block. This production method has low production efficiency and the processing of the impact block The accuracy is low, the scope of application is small, and raw materials are wasted.

Utility model content

The utility model aims at solving the above defects, and provides an impact block mold.

In order to overcome the defects in the background technology, the technical solution adopted by the utility model to solve the technical problem is: an impact block mold, including an upper inner punch, an upper punch, a middle die and a lower punch arranged in sequence from top to bottom, The upper punch is set in the upper punch, the bottom of the upper punch matches the cavity in the middle mold, and the lower punch is also set in the cavity of the middle mold. There is a main mandrel and six mandrels in the lower punch, and the six mandrels are It is divided into three groups and evenly distributed on the periphery of the main mandrel. The cavity of the middle mold is provided with tooth mold 1, and the bottom of the upper punch is equipped with tooth mold 2 matching the tooth mold. The cavity is cylindrical.

In a preferred embodiment of the present invention, the main mandrel and the mandrel are fixed through the mandrel gland and the mandrel seat.

The beneficial effects of the utility model are: high production efficiency, time saving, manpower and material resources saving, and no burrs on the surface of the impact block, reducing subsequent processing procedures, improving processing accuracy and wide application range.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural representation of the utility model.

Fig. 2 is a schematic diagram of the structure of the impact block.

Detailed ways

As shown in Figure 1 and Figure 2, an impact block mold includes an upper inner punch 1, an upper punch 2, a middle die 3 and a lower punch 4 arranged sequentially from top to bottom, and the upper inner punch 1 is arranged in the upper punch 2, The bottom of the upper punch 2 matches the cavity in the middle mold 3, the lower punch 4 is also set in the cavity of the middle mold 3, and the lower punch 4 is equipped with a main mandrel 5 and six mandrels 6, and the six mandrels are 6 points Three groups are evenly distributed on the periphery of the main mandrel 5, the cavity of the middle mold 3 is provided with a tooth mold 1, and the bottom of the upper punch is provided with a tooth mold 2 matching the tooth mold, and the cavity is cylindrical; Mandrel 5 and mandrel 6 are fixed by mandrel gland 7 and mandrel seat 8.

First, iron powder is filled into the cavity formed by the lower punch and the middle die through the automatic feeding device, and then the upper inner punch and the upper punch press the cavity downward to form a circular stamping block in the cylindrical cavity, and then use The lower punch pushes out the impact block. Compared with the previous production process, it greatly saves time, improves production efficiency, and saves manpower and material resources. At the same time, the accuracy of the impact block is improved to ensure product quality.

Claims (2)
