In addition, this method is only applicable to some specific products such as products with symmetrical groove structure, such as cutting knives, A series products, etc.
At the same time, due to the change of product size, the corresponding mold fixture and push shoe need to be remade, so the cost is high and the production cycle is long

Embodiment Construction
[0035] The present invention will be further described in detail below with reference to the drawings and specific embodiments of the specification.
[0036] Figure 1 to Figure 6 An embodiment of the blade powder molding device of the jet powder filler of the present invention is shown. It includes a mold body 1, which is provided with a penetrating cavity 11, and the top and bottom of the mold body 1 are respectively provided with extending molds. The punch 2 and the ejector 3 in the cavity 11, the bottom groove surface of the punch 2 and the top groove surface of the ejector 3 and the cavity 11 form a powder filling area 4, and the side of the mold body 1 is provided with powder The powder injection channel 12 communicating with the filling area 4 is provided with a powder injection component 5 communicating with the powder injection channel 12 outside. When in use, the punch 2 and the ejector 3 are directly extended into the cavity 11 and form a powder filling area 4 between ...

The invention discloses a blade powder blank forming device and method adopting spray type powder filling. The blade powder blank forming device adopting spray type powder filling comprises a mold body. The mold body is provided with a through cavity. The top and bottom of the mold body are provided with a punch pin and an ejector correspondingly, wherein the punch pin and the ejector extend into the cavity. A bottom groove profile surface of the punch pin, a top groove profile surface of the ejector and the cavity define a powder filling area. The side portion of the mold body is provided with a powder spray channel communicating with the powder filling area, and a powder spraying component is arranged on the outer portion of the powder spray channel and communicates with the powder spray channel. The blade powder blank forming method adopting spray tube powder filling is performed through the blade powder blank forming device adopting spray tube powder filling and comprises the following steps of S1 conducting installation, S2 arranging a powder filling area, S3 conducting spray type powder filling, S4 closing the powder spray channel, S5 conducting compression molding, S6 taking out a piece and S7 keeping the steps from the step S2 to the step S6 being circularly executed. The blade powder blank forming device and method adopting spray type powder filling have the advantages that the structure is simple, operation is easy and convenient, the application range is wide, and it can be guaranteed that the compression ratios of all areas can be identical in the powder forming process.
Description
Technical field [0001] The invention mainly relates to the field of solid powder compression molding molds, in particular to a blade powder molding device and a molding method of jet powder filler. Background technique [0002] At present, the powder filling adopts the volumetric method, that is, through the push shoe to move back and forth on the top surface of the mold body, the cavity is filled by the gravity of the powder itself. After the powder is filled, the bottom of the powder in the cavity has a groove structure with the surface of the ejector. Similar shape, but the top surface of the powder is flat with the top surface of the cavity. With the development of cemented carbide CNC blades, complex blade structures continue to emerge. The top and bottom surface of the blade has become more complex and the height of the groove gradually increases. Therefore, the existing packing compression method is adopted. The powder in the powder is a plane, which is inconsistent with ...
