Abstract
The invention discloses a ceramic tile forming die integrating active exhaust and novel hydraulic pressure. A die core part of the forming die comprises multiple layers of PU adhesive structures. Hydraulic oil is injected between the PU adhesive structures. A gap is reserved between an abrasion-resistant needle guard fixed on a die core and a movable valve needle. When a ceramic tile is formed, air and fine powder can be discharged into the ceramic tile along the gap. A powder discharge channel is composed of the die core and a power absorption and clearing plate. The outer end of the powder discharge channel is in linkage with a vacuum generator. The hydraulic oil flows between the PU adhesive structures, and therefore density compensation under pressure can be achieved. When the ceramic tile is formed, the vacuum generator is opened, air and powder in a powder material can be quickly discharged, and therefore delamination of the ceramic tile is drastically eliminated.
Description
Technical field
The present invention relates to a kind of tile forming mould, particularly a kind of piston valve pin type that possesses vacuum pumping function is all pressed tile forming mould.
Background technology
The advanced ceramics brick moulding overwhelming majority adopts containing the low powder of water electrode compressing through mould.In moulding, there are two hang-ups: the one, in powder, containing large quantity of air, be difficult for discharging, very easily cause ceramic tile layering, generally, can only reduce pressing speed, increase evacuation time and solve.Existing air-exhaust mold core is all only on core rod, to offer exhaust outlet, allows the air in powder discharge along gas port.But this is passive exhaust mode, and evacuation time is longer, and easy plug-hole, affect shaping speed and the quality of ceramic tile; The 2nd, when powder skewness and punching press, powder flows and causes tile density inhomogeneous, to cause ceramic tile to burn till rear size unstable, in order addressing this problem, now to adopt common fluid die, but common fluid die is easily bulge in use, and the compensation effect of density is bad.
Summary of the invention
The tile forming mould that provides a kind of novel hydraulic of can intelligent initiative exhaust holding concurrently to be integrated is provided in order to overcome above-mentioned technical disadvantages.
For achieving the above object, technical scheme provided by the invention is: between the wear-resisting needle guard of fixing on core rod and mobilizable needle, leave gap, during tile forming, air and fine powder can enter along gap, and core rod forms and arranges powder passage with the clear powder plate of suction powder.The outer end of row's powder passage connects vacuum generator, and during tile forming, vacuum generator is opened, and makes whole exhaust row powder passage form negative pressure state, and the air in powder and powder can be discharged rapidly, thoroughly solve ceramic tile lamination, and make exhaust passage more unimpeded.Realize intelligent initiative exhaust.
Core rod is the equal die core of hydraulic, comprises multilayer PU plastic structure, and layer by layer, has some back-offs to fix, and guarantees not bulge in use, does not depart from.Hydraulic oil flows between glue-line.Because PU glue has abundant elasticity, so hydraulic oil is faster in intermediate flow, so density compensation effect is more obvious.
After said structure improves, utilize the air-breathing row's powder of negative pressure of vacuum, improve tile forming speed, thoroughly solve layering; Utilize fluid die can guarantee tile forming even density, burn till dimensionally stable, solved two hang-ups in tile forming.
Accompanying drawing explanation
Fig. 1 is the novel tile forming mould structure schematic diagram of all pressing of intelligent exhaust.
The specific embodiment
Accompanying drawings elaborates the present invention, and mould comprises two large divisions.
First: inlay a large amount of wear-resisting needle guards 2 on core rod 1, flat working face when needle 4 is static on the interior top of wear-resisting needle guard 2, lower end cover has "O"-ring, coordinate with the needle sealing shroud 5 in piston plate 4, by the up gas circuit 8 on the descending gas circuit 6 of the needle on piston plate and base plate 7, realize upper and lower running.Gapped between needle 4 and wear-resisting needle guard 2, during work, air and powder enter core rod 1 and the clear powder passage 14 of exhaust of inhaling clear powder plate 9 formation of powder along gap, the outside of the clear powder passage 14 of exhaust connects vacuum generator (scheming not shown), during assurance work, in whole passage, form negative pressure of vacuum, accelerate the discharge of air and powder, by arrow S, complete the air-breathing row's powder of negative pressure of vacuum process.Wherein acting as of sealing strip 16 and sealing and dustproof circle 17 improved sealing and dustproof effect.
Second portion: all die core 1 is hydraulic core rod, its top has concave surface, in concave surface, there are three layers of PU glue 15, be specially ground floor high-performance PU glue 10 by after artificial back-off, press second layer high resiliency PU glue 11, injection liquid force feed 13 in ground floor high-performance PU glue 10 and second layer high resiliency PU glue 11, oil sump in core rod communicates, cover again the 3rd layer of antiseized powder PU glue 12 above, hydraulic oil 13 rapid flow between glue-line during work, the density contrast causing to compensate powder inequality.
Claims (5)
1. a discharge type is all pressed tile forming mould, comprise the clear powder plate of core rod, piston plate, base plate and suction powder, on core rod, be embedded with a large amount of wear-resisting needle guards, in wear-resisting needle guard, there is needle, in piston plate, there is needle sealing shroud corresponding position, it is characterized in that: gapped between needle and wear-resisting needle guard, air and powder can enter core rod by described gap and form the clear powder passage of exhaust with inhaling the clear powder plate of powder, and the outside of the clear powder passage of exhaust is connected with vacuum generator.
2. mould according to claim 1, is characterized in that: on piston plate, have the descending gas circuit of needle, have the up gas circuit of needle on base plate.
