Description

Upper briquetting mold

technical field

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

Background technique

The upper pressing block is a component used in electric tools. The existing upper pressing block production method requires secondary processing after forming to reduce the burrs on the surface of the bevel gear. This production method is inefficient and the upper pressing block The processing accuracy is low, the scope of application is small, and raw materials are wasted.

Contents of the invention

The utility model aims at solving the above defects, and provides an upper briquetting die.

In order to overcome the defects in the background technology, the technical solution adopted by the utility model to solve the technical problems is: an upper briquetting die, including an upper punch, a middle die, a lower punch, a lower second punch and a mandrel, the mandrel Pass through the lower second punch, the next punch and the middle mold respectively, the next punch is set on the lower second punch, the next punch and the lower second punch are both installed in the inner cavity of the middle mold, and the upper punch is set directly above the middle mold. The inner cavity of the middle mold is T-shaped.

In a preferred embodiment of the present invention, a cavity matching the mandrel is provided in the upper punch.

The beneficial effects of the utility model are: high production efficiency, saving time, manpower and material resources, and the surface of the upper pressing block has no burrs, reduces subsequent processing procedures, improves processing accuracy, and has a wide range of applications.

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 upper pressing block.

Detailed ways

As shown in Figure 1 and Figure 2, an upper briquetting mold includes an upper punch 1, a middle die 2, a lower punch 3, a lower second punch 4 and a mandrel 5, and the mandrel 5 passes through the lower second punch 4, respectively. The next punch 3 and the middle mold 2, the next punch 3 is set on the lower second punch 4, the next punch 3 and the lower second punch 4 are both installed in the inner cavity 6 of the middle mold, and the upper punch 1 is set directly above the middle mold 2 , the cavity 6 of the middle mold is T-shaped; the upper punch 1 is provided with a cavity 7 that matches the mandrel 5 .

First, the iron powder is filled into the inner cavity formed by the lower second punch, the next punch and the middle mold through the automatic feeding device, and then the upper punch presses the inner cavity downwards. After the stamping is completed, the upper punch moves up, and the next punch and The lower two punches push the upper briquetting upwards to complete the stamping of the upper briquetting. Using this mold to produce the upper briquetting, compared with the previous production process, greatly saves time, improves production efficiency, and saves manpower and material resources. The precision of the upper pressing block is improved to ensure the product quality.

Claims (2)

1. an upper briquetting die, characterized in that: comprise an upper punch, a middle die, a lower punch, a lower second punch and a mandrel, and the mandrel passes through the lower second punch, the next punch and a middle die respectively, The next punch is sleeved on the lower second punch, both the next punch and the lower second punch are set in the inner cavity of the middle mold, the upper punch is set directly above the middle mold, and the inner cavity of the middle mold is T-shaped . 2. The upper briquetting die according to claim 1, wherein a cavity matching the mandrel is provided in the upper punch.
