(3) beneficial effect
Compared with prior art, after the air that the utility model adopts aspiration pump to find time in molding space, carry out again moulding, improved the quality of shaped article, and internal mold surface is coated with wearing layer, improved the service life of mould.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the structural representation of the mould on powder former.
Fig. 2 is that the utility model is for the perspective view of the mould on powder former.
Fig. 3 is that the utility model is for the horizontal section schematic diagram of the mould on powder former.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The utility model for the structure of the mould on powder former as depicted in figs. 1 and 2, its cross-section structure as shown in Figure 3, should comprise internal mold 1 for the mould on powder former, be sleeved on the external mold 2 outside internal mold 1, the depression bar 3 of movable set in internal mold 1, be fixedly mounted on holder 4 and the push rod 6 of movable set in holder 4 of internal mold 1 bottom, one end that push rod gos deep in internal mold 1 is provided with the top board 61 cooperatively interacting with internal mold 1 inwall, between top board 61 and depression bar 3, is provided with molding space 14; Between top board 61 and holder 4, leave space 13, offer the passage 12 of one end connected space 13 on internal mold 1, the other end of passage 12 connects aspiration pump 8 by breather pipe 7.
The inner wall surface of internal mold 1 is coated with wearing layer; The setting of wearing layer, in the service life of having improved mould, improves product surface quality.
On holder 4, be provided with the location shaft shoulder 41 stretching in internal mold 1, between the location shaft shoulder 41 and internal mold 1, be provided with an O RunddichtringO 91; Between holder 4 and push rod 6, be provided with the 2nd O RunddichtringO 92.The setting of sealing ring avoids outside air to enter molding space, affects the Forming Quality of product.
The bottom of internal mold 1 is provided with step 11, and one end of step 11 is against the bottom end face of external mold 2.Step 11, against external mold 2 bottom surfaces, also ejects internal mold 1 in the time of can preventing ejecting product.
Holder 4 is fixedly mounted on the bottom of step 11 by a plurality of screws 5.
Add man-hour, powder is filled to after molding space, depression bar enters in internal mold under the drive of upper power set, starts aspiration pump, molding space is taken out to true hole, then carry out the moulding of powder-product.After the air that the utility model adopts aspiration pump to find time in molding space, carry out again moulding, improved the quality of shaped article, also there is simple in structure, easy to operate feature.
These are only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
