Specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figs. 1-2, a kind of charging of automatic Powder forming press and demoulding mechanism, the mould including having die hole 11
Plate 1, the support frame 3 of the lower die 2, support shuttering 1 that cooperate with die hole 11 at sealing and can move up and down in die hole 11, driving branch
The shaft 4 that support 3 is gone up and down.1 replaceable of template is fixed on 8 top of workbench, and for 8 sliding sleeve of workbench in guide post 7, guide post 7 is solid
Due to rack (not shown).Support frame 3 includes upper cross plate 33 and lower cross plate 34, by lower vertical between upper cross plate 33 and lower cross plate 34
Column 32 is fixed together, and support frame 3 is by being fixed on 31 support shuttering 1 of upper pillar stand of the top of upper cross plate 33.Support frame 3 is tight
The lower section of adjacent upper cross plate 33 is equipped with upper plate 35, is equipped with lower roof plate 36 close to the top of lower cross plate 34, upper plate 35 is located at
It the position of support frame 3 can up and down adjustment.Position of the lower pillar stand 32 between upper plate 35 and lower roof plate 36 is also cased with buffering elastic
Spring 37, buffer spring 37 avoid the staged oscilaltion of support frame 3, mitigate noise and the vibration of equipment, improve service life.
Shaft 4 crosses the middle and lower part of support frame 3, between upper plate 35 and lower roof plate 36 and is cased with charging cam 41 and demoulding cam
42.Upper plate 35 is fixed with upper roller 351 corresponding with charging cam 41, and lower roof plate 36 is fixed with corresponding with demoulding cam 42
Bottom roller 361.Shaft 4 can drive its rotation by motor or other modes, when the flange of charging cam 41 is rotated to top
Upper plate 35 can be jacked up and then increase template 1, lower die 2 cooperatively forms the die cavity of upper end opening with die hole 11；Demould cam 42
Flange rotate to lower section can push lower roof plate 36 so that make template 1 decline, lower die 2 support finished product be exposed to 1 upper surface of template.
The configuration of the present invention is simple, knockout press is strong and can guarantee the precision of charging and demoulding, reduces the load of equipment dynamic, improves equipment
Service life.
The specific structure that the present invention adjusts upper plate 35 is as follows, including the first pillar 51, the first worm gear 52, the first worm screw 53
With first motor 54.Upper plate 35 by the first pillar 51 can up and down adjustment be installed on the lower section of upper cross plate 33,52 spiral shell of the first worm gear
Line is set in the first pillar 51, and the first worm screw 53 engages with the first worm gear 52, and the first worm screw 53 is driven by first motor 54 and rotated.
First motor 54 rotates through dependency structure transmission, so that it may make 51 up and down adjustment of the first pillar, be located to change upper plate 35
The position of support frame 3 may ultimately reach the height for adjusting die cavity.But it is by acting on Xia Ding that cam 42 is demoulded in this structure
Plate 36 realizes decline template 1, and the position that lower roof plate 36 is located at support frame 3 immobilizes, therefore the position that template 1 declines every time
Set it is all constant, guarantee demoulding precisely in place.
The invention also includes can up and down adjustment the second pillar 61, the second worm gear 62, the second worm screw 63 and the second motor 64,
Lower die 2 is fixed on 61 top of the second pillar, and 62 thread set of the second worm gear is in the second pillar 61, the second worm screw 63 and the second worm gear
62 engagements, the second worm screw 63 are driven by the second motor 64 and are rotated.Wherein, the second worm gear 62, the second worm screw 63 and the second motor 64
It to be fixed on the corresponding position of rack (not shown), can not be changed, the rotation of the second motor 64 only changes the position of the second pillar 61, from
And realize the fine adjustment to die cavity, therefore will not impact to demoulding of the invention.
Die cavity can also be formed the form for being designed as incrementally increasing by this structure, convenient to charge in batches, specifically, as schemed
Shown in 3, charging cam 41 includes basic circle section 411, ascent stage 412 and maintenance section 413；When ascent stage 412 is located above, die cavity is high
Degree gradually increases；When maintaining section 413 to reach top, die cavity height is maximum.
Above-described, only presently preferred embodiments of the present invention cannot limit the scope of implementation of the present invention, it is all according to
Equivalent change made by scope of the present invention patent and decoration, should still belong in the range of the present invention covers.
