Description

A kind of feed mechanism and compression molding device

Technical field

The utility model is related to powder compacting equipment technical field, and in particular to a kind of feed mechanism and compression molding are filled Put.

Background technology

During powder pressing forming, conveying pipeline by powder carry to feed box, by feed box be charging mould interval, Quantitative feed, feed box moves to charging mould top along mounting platform, and powder is dropped down onto in mold cavity under relying on deadweight, conveying Powder in pipe is supplemented the powder in feed box by deadweight, and until mold filling is finished, feed box resets, then by upper Low punch is suppressed the powder in die cavity, and mounting platform drives charging mould descending, product stripping, by feed box by the demoulding Product afterwards is pushed into charging mould relative to the opposite side of feed box, obtains shaped article, in order to improve production efficiency, leads to Multiple die cavities are often formed in charging mould, a feed box is that multiple die cavities fill powder simultaneously, when product needed bottom Filling A material, when upper strata filling B expects, then set two feed boxes, and A material and B material are filled respectively, and usually, two feed boxes are respectively provided with In the same side of charging mould, demoulding product is pushed into charging mould phase by feed box after powder filling is carried out for charging mould For the opposite side of feed box, taking product away for operating personnel carries out subsequent processing, therefore two feed boxes are arranged in feed Mould is on two sides of the V-shape on summit.

Multiple die cavities fill powder and although improve production efficiency simultaneously, but because current most of charging apparatuses are equal Fed using volumetric method, it is ensured that the fill volume in each die cavity quite, that is, is defaulted as filling quality quite, is controlled into this Product uniformity, however, the production requirement for needing each product weight deviation of strict control, this cavity with fashion material side Formula can cause to exist between each cavity fill and interfere, because conveying pipeline is to the powder supplement of feed box, and feed box Relying on powder deadweight to the filling of the powder of die cavity is carried out, and the flow regime of powder is by feed box to cavity fill amount, filling The multifactor impacts such as speed, the delivery rate of conveying pipeline is also influenceed by the blanking speed of feed box, causes the flow regime of powder Can not be identical in real time.

Therefore, existing bottomless cylindrical feed box is rounded to the blanking port of die cavity blanking, feed box along V-shape list When side multiple die cavities apicad are close to, each die cavity successively can be sequentially reached, and there is overlap in each die cavity loading time, on One die cavity is also unfilled to be finished, and next cavity fill has started to so that flow regime when powder is to each mold filling is not Together, cause the packing density in each die cavity different, have impact on the uniformity of each die cavity powder weight；Secondly as existing defeated Expects pipe is considered due to practicality, and non-vertically located at feed box top, but obliquely stretched at an angle with mounting platform At feed box center of top, powder also can more be rushed at the front of pipeline extended line when falling from conveying pipeline by inertia effects, When two feed boxes are set along V-shape, the powder of conveying pipeline is easier to fall into feed box in front of conveying pipeline extended line Side, causes the side powder packing higher, and the corresponding die cavity powder packing density in the side is bigger, although fill volume is suitable, But the powder weight in actual each die cavity has obvious deviation, it is unfavorable for the uniformity of finished product, it is necessary to frequently adjusting device Packed height, be also unfavorable for stabilization continuous production.

Utility model content

Therefore, the technical problems to be solved in the utility model is feeding when overcoming multi-layer powder filling in the prior art Box is interfered to existing between multiple cavity fills, and powder flow regime real-time change causes product weight deviation big Defect, thus provide it is a kind of advantageously reduce between multiple mold fillings interfere, reduce product weight deviation, improve into The feed mechanism of product uniformity.

Another technical problem to be solved in the utility model is to overcome the conveying pipeline being obliquely installed in the prior art Powder is easier to fall into side of the feed box in front of conveying pipeline extended line, causes that the side mold filling weight is bigger than normal to be lacked Fall into, so that providing a kind of feed box that is prevented effectively from causes the feeder uneven to each mold filling because conveying pipeline is obliquely installed Structure.
