Description
Technical field
This utility model relates to dry-pressing formed technical field, particularly to a kind of ceramic dry-pressed device.
Background technology
Ceramic dry-pressed, is the forming method of a kind of ceramic powders, it is simply that be packed in metal die cavity by dry powder blank,
Pressing and become dense green, dry-pressing formed method is simple to operate, production efficiency is high, be prone to automatization, is conventional
One of shaping method of ceramics, at present, when ceramic body makes, puts into blank in mould, is then installed by mould complete, profit
It is with the active force between mold component, blank is compressing, although this kind of mould structure is simple, but does not does a product,
It is accomplished by dismounting mould, very a labor intensive by hand.
In order to solve the problems referred to above, in the Chinese patent document that number of patent application is " 200920191083.1 ",
Describe the composite die of a kind of external shell of alumina ceramic fuse, during work, the blank mixed up is poured in die cavity, by press
Being declined by top board so that the blank of upper trimming die abundant pressing die intracavity, be fully compacted blank, after pressing, top board rises, pressure
Machine passes through liftout tank by liftout plate jack-up, the liftout plate effect by knock-pin, jack-up lower mold, final molding pint mould.
But, above-mentioned this composite die and existing most of mould, be all by hydraulic cylinder by products formed from
Eject in die cavity, owing to the hydraulic pressure of hydraulic cylinder is unstable, be easily caused the ejecting force that hydraulic cylinder is applied on products formed
Excessive, when the excessive situation of ejecting force occurs, the side of products formed can be caused to produce bigger friction with die cavity, cause molding
The abrasion of product, greatly reduces the dry-pressing formed quality of products formed.
Utility model content
The purpose of this utility model is to provide and a kind of reduces the abrasion that products formed is subject to, thus it is dry-pressing formed to improve products formed
The ceramic dry-pressed device of quality.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of ceramic dry-pressed
Device, including frame, described frame is provided with lower mold, described lower mold is placed with forming blocks and runs through and be arranged on forming blocks

Lower surface, now, infrared ray sensor 17 senses that forming blocks 4 moves to and upper mold 2 abutted position, by anti-for this abutting signal
Feeding controller 18, controller 18 drives motor 5 to electrically connect with first, and controller 18 controls the first driving motor 5 and works, and first
Drive motor 5 to drive rotating disk 19 to rotate forward, strain rope 7, thus forming blocks 4 is strained and fixed in upper mold 2；
Being provided with the guide 8 that the movement to rope 7 guides in upper mold 2, in the present embodiment, guide 8 is for leading
Offering 2 relative pilot holes of in the vertical direction 801 on block, guide pad, rope 7 in the vertical direction is led through two
To hole 801, rope 7 moves up and down in 2 pilot holes 801, and the movement of rope 7 is guided by 2 pilot holes 801, makes to stretch
Contracting in the vertical direction moves up and down；
The upper surface of lower mold 3 is provided with guide pillar 12 straight up, forming blocks 4 offers and coordinates with guide pillar 12 grafting
Spliced eye, is inserted in forming blocks 4 on guide pillar 12 by spliced eye, thus forming blocks 4 is placed on the position in lower mold 3 and carries out determining
Position.
The work process of the present embodiment is as follows: forming blocks 4 is placed in lower mold 3, is filled into by blank in forming hole 401,
3rd actuator 11 works, and drives lower mold 3 move upward and carry out matched moulds with upper mold 2, the briquetting 13 in upper mold 2 and forming hole
401 male-female engagement, briquetting 13 coordinates lower mold 3 to be compacted blank in forming hole 401, thus forms products formed, now, molding
The upper surface of block 4 abuts with the surface of upper mold 2, and sensing device receives abutting signal, controls the first driver part 21 and works, hangs
Hook 6 moves up, thus pulls up guy tightening 7, forming blocks 4 is strained and fixed in upper mold 2 by rope 7, and then, the 3rd drives
Moving part 11 drives lower mold 3 to move down, and lower mold 3 progressively disengages with forming blocks 4 and contacts, and the products formed in forming hole 401 is at self
Under the effect of gravity, drop in forming hole 401 lower mold 3, thus realize the automatic demoulding of products formed.
Embodiment 2: a kind of ceramic dry-pressed device, as shown in Figure 4, difference from Example 1 is, fixed mechanism
Including jig arm 15 and the second actuator 14, in the present embodiment, the second actuator 14 is rotary cylinder, and rotary cylinder is arranged on
On the lower surface of upper mold 2, and fixing with one end of jig arm 15 being connected, the quantity of rotary cylinder and jig arm 15 is 2, distinguishes position
In the left and right sides of forming blocks 4,2 rotary cylinders drive 2 jig arm 15 to rotate against, and are coordinated molding by 2 jig arm 15
Block 4 is fixedly clamped wherein, thus realizes being fixedly clamped in upper mold 2 forming blocks 4；Jig arm 15 contact with forming blocks 4 one
End is provided with cushion pad 16, and in the present embodiment, cushion pad 16 is made up of elastomeric material, has certain elasticity, jig arm
15 rotate, cushion pad 16 and forming blocks 4 Elastic Contact, jig arm 15 can be avoided directly to connect with forming blocks 4 by cushion pad 16
Touch, reduce when jig arm 15 presss from both sides forming blocks 4 and produce abrasion, improve jig arm 15 and clamp the stability of forming blocks 4.
The work process of the present embodiment is as follows: forming blocks 4 is placed in lower mold 3, is filled into by blank in forming hole 401,
3rd actuator 11 works, and drives lower mold 3 move upward and carry out matched moulds with upper mold 2, the briquetting 13 in upper mold 2 and forming hole
401 male-female engagement, briquetting 13 coordinates lower mold 3 to be compacted blank in forming hole 401, thus forms products formed, now, second
Actuator 14 works, and drives jig arm 15 to clamp forming blocks 4 after rotating, and makes forming blocks 4 be clamped and is fixed in upper mold 2, then, the
Three actuators 11 drive lower mold 3 to move down, and lower mold 3 progressively disengages with forming blocks 4 and contacts, and the products formed in forming hole 401 exists
Under the effect of self gravitation, drop in forming hole 401 lower mold 3, thus realize the automatic demoulding of products formed.
Embodiment 3: a kind of ceramic dry-pressed device, is with the difference of embodiment 1, the 3rd actuator 11 includes
