Description

A mold structure for high-precision powder molding machine

technical field

The utility model relates to powder metallurgy equipment, in particular to a mold for a powder molding machine, in particular to a mold structure for a high-precision powder molding machine.

Background technique

Powder metallurgy is the process and technology of manufacturing metal powder and using metal powder as the basic raw material to manufacture metal materials and heterosexual products. Among them, molds are indispensable process equipment for manufacturing powder metallurgy products. The structure of the existing mold structure for powder molding machines adopts an upper mold and a lower mold respectively on the upper and lower sides of the mother mold. Rod connecting rod, the length of the middle rod connecting rod is too long and it is easy to deflect and cause mold damage. In addition, the current formwork is inconvenient to install. Because the mother type is a split type, repeated debugging is required during installation, the position is difficult to grasp, and the installation is more cumbersome.

Utility model content

The purpose of this utility model is to provide a mold structure for a high-precision powder molding machine. The mother mold is an integral structure, and the middle rod seat is fixed under the mother mold, so that the length of the middle rod can be shortened, so that the mold will not be damaged.

For solving the problems of the technologies described above, the technical solution of the utility model is:

The mold structure for a high-precision powder molding machine includes an upper mold and a lower mold, a middle mold between the upper mold and the lower mold, and a mother mold is installed on the middle mold. It is characterized in that the mother mold is an integrated structure; The upper mold can be connected with the upper formwork through the upper punch gasket above it; the lower mold is connected with the lower formwork through the lower mold seat below it; the middle rod seat is installed under the mother mold, and the middle rod seat faces The lower link has a middle rod.

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

The parent mold of the utility model has an integrated structure, which prevents powder leakage during the process of pressing the product, and can improve the precision of the mold. The middle rod seat is designed to be fixed under the mother mold. Compared with the existing technology, the length of the middle rod is shortened, and the problem of the original machine that the middle rod is too long and easy to damage the mold is solved. The mother type of the utility model is all one-piece structure, and installation is very convenient.

Description of drawings

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

Among them, 1. Upper mold, 2. Lower mold, 3. Female mold, 4. Upper punch gasket, 5. Lower mold seat, 6. Middle rod seat, 7. Middle rod.

detailed description

The utility model is further elaborated in conjunction with the accompanying drawings.

As shown in Figure 1, the mold structure for the high-precision powder molding machine of this embodiment includes an upper mold 1 and a lower mold 2, a middle mold between the upper mold 1 and the lower mold 2, and a mother mold 3 is installed on the middle mold , the female mold 3 is an integrated structure; the upper mold 1 can be connected with the upper template through the upper punch gasket 4 above it; the lower mold 2 is connected with the lower template through the lower mold seat 5 below it; A middle rod seat 6 is installed below the female type 3, and a middle rod 8 is connected to the middle rod seat 6 downward.

The female mold 3 of the utility model has an integrated structure, and no powder material will leak during the process of pressing the product, and the precision of the mold can be improved. The middle rod holder 6 is designed to be fixed under the female mold 3. Compared with the prior art, the length of the middle rod 7 is shortened, which solves the problem that the mold of the original machine is easy to be damaged because the middle rod is too long. The female form 3 of the present utility model has an integral structure, and the installation is very convenient.
