Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "bottom", "below", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-2, the utility model provides a local material bodiness mould, including upper die base 10 and the die holder 12 that cooperates upper die base 10 to use, upper die base 10 below is provided with the extrusion drift 22 to the local bodiness of product 50 first time and to the shaping drift 24 of the local bodiness of product 50 second time. Two forming female dies 26 corresponding to the positions of the extrusion punch 22 and the forming punch 24 are arranged on the lower die holder 12, and a limit block 28 is arranged in the forming female die below the forming punch 24. The height of the stop block 28 is slightly higher than the inner diameter of the forming die so that the forming punch 24 is pressed down to thicken the product 50 at the outer diameter of the stop block 28.

Wherein, the outside cover of extrusion drift 22 is equipped with locating piece 30, and the shape of locating piece 30 and the local shape cooperation of shaping die 26 and product. The positioning block 30 is clamped on the pressing block 32, a nitrogen spring 34 is arranged above the positioning block 30, a spring fixing block 36 is arranged at the top of the nitrogen spring 34, and the bottom of the spring fixing block is connected with an ejector rod which abuts against the positioning block 30. When the device is used, the nitrogen spring 34 can be driven to push the ejector rod below the device to move in the limit stroke of the pressing block 32, the product is positioned by the positioning block 30 in advance, and the product is pressed downwards by the extrusion punch 22 to thicken the product.

Further, a fixed plate backing plate 14 and a fixed plate 16 are arranged below the upper die base 10, and a cavity plate backing plate 18 and a cavity plate 20 are arranged above the lower die base 12. The pressing block 32 and the positioning block 30 are disposed at the bottom of the fixing plate 16. The fixture blocks 48 are arranged on the top of the cavity plate 20, and the forming cavity die arranged at the bottom of the forming punch 24 is clamped on the cavity plate 20 through the fixture blocks 48.
