Abstract
Description
- This invention relates to the quick replacement of those parts which determine the tile format in press-mounted moulds for forming ceramic tiles.
- In the known art, forming moulds are complex structures comprising a plate, known as the bench protector, which is securely fixed to the bed of the press.
- Hydraulic cylinder-piston units, also known as columns or feet, extend upwards from the bench protector plate to support a vertically movable upper die plate in which through seats are provided to create the forming cavities for the powder.
- In a position below the die plate, the bench protector plate carries a slab, known as the block, which is movable vertically relative to the bench protector plate by a series of rods rising from the press raising system and passing through holes in the bench protector plate to engage the block bilaterally.
- A number of pads equal to the number of through cavities of the die plate are securely fixed on the block, on each pad there being fixed, generally by magnetic fixing, one of the two dies forming the rear surface or exposed surface of the tile. Said two dies are known respectively as the reverse face die for the rear surface and the obverse face die for the exposed surface.
- The tile format is defined by the die plate cavities and the dies, and to a certain extent by the underlying pads which must have dimensions just less than those of the dies.
- Dies such as the aforedefined are described in Italian Industrial Model Patent No. 235153 in the name of the same applicant.
- Hence in known moulds, changing the tile format is a lengthy and laborious operation.
- The die plate must be released from its cylinder-piston support units and removed from the press.
- Before removing the dies, which is fairly simple because of their magnetic fixing, the pads must be released from the block and removed from the press.
- The bed (consisting of the bench protector plate/block/bellows/feet) must then be detached and removed from the press.
- Then the block of the new format must be remounted on the bench protector plate, the respective pads and dies must be mounted on the block and the die plate of the new format be remounted, after which lengthy and laborious mutual settings must be effected on the various parts before commencing the new production.
- These briefly described operations require a time of not less than four hours in total.
- The object of this invention is to provide a mould having quickly interchangeable parts to enable the format to be easily changed in a short time, including the final setting operations.
- This object is attained by a mould having the characteristics defined in the claims.
- Essentially the mould of the invention comprises a bench protector plate, a block associated with said bench protector plate by raising means, at least one pad securely fixed to said block, and a series of cylinder-piston units supporting a vertically movable die plate. It differs from the known art by a base plate fixed to the block by locking means operable from the outside and on which the pads are securely fixed, and a manipulator bar arranged to connect said die plate and said pads together to maintain the assembly coherent during the replacement.
- The functional and constructional merits and characteristics of the invention will be apparent from the ensuing detailed description given by way of non-limiting example with reference to the accompanying drawings.
- Figure 1 is a schematic view of the invention in its working configuration.
- Figures from 2 to 5 show the invention of Figure 1 during the various stages of changing the format.
- Figure 6 is a plan view of a component of the invention.
- Figure 7 shows the section VII-VII of Figure 6.
- Figure 8 shows the section VIII-VIII of Figure 6.
-
- The figures show the
crosspiece 1 of the press raising system, on which thebench protector plate 2 is securely fixed. - From the
crosspiece 1 there upwardly extend tworods 11 which pass throughholes 21 in thebench protector plate 2, to engage in theoverlying block 3. - The bilateral locking means between the
rods 11 andblock 3 are omitted as these are of usual type. - The
rods 11 are operated hydraulically to raise theblock 3 from thebench protector plate 2 when required. Abellows 31 protects the region between theblock 3 andbench protector plate 2 against dust. Four hydraulic cylinder-piston units 22 extend upwards from thebench protector plate 2 to support thedie plate 4 by fourequidistant bushes 41, also known as loading spacers. - A
screw 42, passing through thebush 41, fixes thedie plate 4 to the piston rod of the cylinder-piston unit 22. Thedie plate 4 comprises thecavities 43 within which the powder is pressed. - A
plate 5, known as the pad linkage plate, is rested on and fixed to theblock 3 bymagnetic means 32, and has the same plan dimensions as the block. - The
block 3 also comprises fourseats 33 for four hydraulic cylinder-piston units 34 for raising thepad linkage plate 5 from the block after deactivating themagnetic means 32. - A number of
pads 6 equal to the number ofcavities 43 of thedie plate 4 and having plan dimensions just less than those of the respective cavity are securely fixed by usual means, not shown, to thepad linkage plate 5. - The respective reverse or obverse face die 61 is then fixed by usual magnetic means to each
pad 6. - The figures also show the press
upper crosspiece 10 which by usual magnetic means supports theupper dies 101 to be inserted into the cavities of thedie plate 4. - The invention is completed by a manipulator bar 8 (see Figure 3) which during format change maintains the
die plate 4, thepads 6 and thepad linkage plate 5 joined together and centered, and bysuitable spacers 81. - The format is changed in the following manner.
- The die plate is lowered by operating the cylinder-
piston units 22 until they are flush with, or slightly below, the upper face of thepads 6, thedies 61 then being removed after deactivating the magnetic locks (Figure 2), while at the same time theblock 3 is raised by thehydraulic rods 11 until it rests against the lower side of thedie plate 4. - The
screws 42 which connect thedie plate 4 to the piston rods of the cylinder-piston units 22 are then slackened. - Having done this the
die plate 4 is again raised (Figure 3), it is disengaged from thebushes 41, andspacers 81 having their top flush with the upper surface of the die plate are placed on thepads 6. - At this point the
manipulator bar 8 for maintaining the die plate, the pads and the underlyingpad linkage plate 5 joined together as a single assembly, is fixed onto thedie plate 4 with thespacers 81 interposed. - The
fixing screws 42 between the die plate and cylinder-piston units 22 are then removed completely and the cylinder-piston units 34 are operated to raise said assembly as shown in Figure 4. - The assembly can then be collected and removed from the press by a usual
fork lift truck 100, after lowering the cylinder-piston units 34. The assembly of the new format previously assembled outside the press is then mounted by the reverse operations. - By virtue of the invention the operations needed to replace those parts of the mould involved in changing the tile format require a total time not exceeding one hour.
