On 6, small head makes the interiors of products of production have cavity in the centre of die cavity.
Embodiment 6, the slurry being stirred are put into die cavity, are poured and are struck off after filling, and moulding box is removed, next moulding box again then
To pour into a mould.After product strength in the moulding box first poured into a mould is high, moulding box is moved at stripper apparatus, the positioning of automatic start moulding box
(while being also that left and right rail 13 lengthens), starts mechanical gripper and together hangs away blocking material frame and upper mould, start mould emptier and end
Die adapter 9 is docked, start machinery locked mode briquetting 7 rotate to an angle (vertical 90 degree) not press against lock module 7, be at this moment stripped
9 one pulling force of mechanism opposite end die adapter make front side template 2, bed die 17, every the end face of mould 4, rear side template 5 and product and end mould 6
Distance of separation (will be more greatly if being fixed with plug distance of separation on the mould 6 of end);Then start mechanical power to act on force-transmitting block 20, make
Front side template 2, bed die 17, move every the sliding part 15 of mould 4, rear side template 5, pass through respectively between sliding part 15 and sliding part 15
The active force one for pulling open ring 11 draws one, and it is conveniently stripped to produce equidistant gap, make product and front side template 2, bed die 17, every
Distance of separation between mould 4, rear side template 5, i.e. die opening state;Finally start mechanical gripper and lift Product transport to specified location.
Starting mechanical power again and acting on force-transmitting block 20 makes front side template 2, bed die 17, is moved every the sliding part 15 of mould 4, sliding part 15 with it is sliding
Mutual jam-packed between moving part 15, front side template 2, bed die 17, adjacent to each other in place every mould 4, rear side template 5 is realized, that is, closes mould
State;At this moment 9 one thrusts of mould emptier opposite end die adapter make end mould 6 be adjacent to front side template 2, bed die 17, every mould 4, rear side mould
Plate 5, at this moment with machinery locked mode briquetting 8 rotate to an angle (horizontal 180 degree) press against lock module 7 i.e. moulding box pass mould;Mechanical gripping
Hand, which together hangs block pulp frame with upper mould, comes good and sound, while mould emptier and moulding box positioning (while be also left and right rail 13 lengthen)
Exiting, 1 time connection track of moulding box chassis walks wheel 14, and now moulding box leaves de-molding position in orbit in the presence of by external force, etc.
Treat that next moulding box equipped with product arrives.Empty moulding box is finally moved to pouring position and waits grouting.
Embodiment 7, moulding box is first automatically positioned, and the material being stirred is put into stone inframe, then that the material of stone inframe is uniform
It is layered in die cavity, stone frame retracts original place.Starting pressing mechanism immediately makes mould move down in place, and starting lifting body makes biography
Power bar passes through the cover being fixed on bed die 17 to promote movable die block 21 to rise and moved into place, and (position has 3 kinds:1 only upper mould moves
It is dynamic in place, 2 only movable die block 21 move into place, on 3 mould relative movement in place while the relative movement of movable die block 21 arrive
Position), a little time is then waited, pressing mechanism and upper mould are removed simultaneously, and now lifting body declines and separated in place with transmission rod,
Moulding box positioning lift, moulding box leave stone and pressing position in orbit in the presence of by external force, moulding box moves forward, empty moulding box
And come.After product strength in the moulding box being shaped is high, moulding box is moved at stripper apparatus, the positioning of automatic start moulding box
(while being also that left and right rail 13 lengthens) device, starts mould emptier and is docked with end die adapter 9, machinery rotates locked mode briquetting 7
Certain angle (vertical 90 degree) not press against lock module 7, and 9 one pulling force of at this moment mould emptier opposite end die adapter make front side template 2, bottom
Mould 17, (will if being fixed with plug distance of separation on the mould 6 of end every the end face of mould 4, rear side template 5 and product and end mould 6 distance of separation
It is big);Then start mechanical power to act on force-transmitting block 20, make front side template 2, bed die 17, every mould 4, the slip of rear side template 5
Part 15 moves, and draws one by pulling open the active force one of ring 11 respectively between sliding part 15 and sliding part 15, produces equidistant
Gap is conveniently stripped, makes product and front side template 2, bed die 17, the distance of separation between mould 4, rear side template 5, that is, molds shape
State;Finally start mechanical gripper and lift Product transport to specified location.Start again mechanical power act on force-transmitting block 20 make front side mould
Plate 2, bed die 17, move every the sliding part 15 of mould 4, mutual jam-packed between sliding part 15 and sliding part 15, realize front side template
2nd, bed die 17, adjacent to each other in place every mould 4, rear side template 5, that is, mould state is closed;At this moment mould emptier opposite end die adapter 9 one pushes away
Power makes end mould 6 be adjacent to front side template 2, bed die 17, every mould 4, rear side template 5, and locked mode briquetting 8 is at this moment rotated certain angle with machinery
Degree (horizontal 180 degree) press against lock module 7 i.e. moulding box and close mould;Moulding box positioning (while being also that left and right rail 13 lengthens) device exits,
1 time connection track of moulding box chassis walks wheel 14, and now moulding box leaves de-molding position in orbit in the presence of by external force, under wait
One moulding box equipped with product arrives.Empty moulding box is finally moved to stone and pressing position etc. is to be formed.
Finally it should be noted that:Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System;Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand:It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution;And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
