Description
Technical field
The invention belongs to the technical field of the multi-layer ceramics with cavity body structure, particularly relate to the forming method of the fine cavity body structure of multi-layer ceramics.
Background technology
The shaping of multilayer ceramic cavity structure adopt shaper filling technology more, and in conjunction with isostatic pressing process, obtain the ceramic package with certain cavity geometry, shaper can select metal derby or sillicon rubber blocking.No matter the method, owing to being subject to the restriction of Mold Making, being processing metal block or sillicon rubber blocking, all comparing and waste time and energy, and can only be used for the shaping of particular cavity shape after processing, does not have generality.The making of sillicon rubber blocking is relatively simple, and cost is lower, but sillicon rubber blocking machining accuracy is not high, and easily distortion after going through use for several times, can not ensure to become more meticulous the requirement of producing in a large number mould and die accuracy.Flowing filling technique can the cavity of shaping arbitrary shape, can recycling rate of waterused high, and have generality, but be limited to elasticity and the hardness of soft silica gel epidermis, when shaping for more fine cavity body structure, soft silica gel epidermis ratio is easier to breakage.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the method that the gel filled body of a kind of laminating prepares fine cavity body structure multi-layer ceramics, the method is especially high to the forming machining precision of the complicated fine cavity body structure of multi-layer ceramics, is not easy damaged can recycling.

As preferably, described aluminium sheet is provided with locating dowel, and correspondingly on described curtain coating ceramic chips is provided with locating hole, and the locating hole on curtain coating ceramic chips through the locating dowel on aluminium sheet, thus is fixed on aluminium sheet.
As preferably, described filling mould tire preparation process comprises the following steps: first silica gel monomers A and flocculating agent B two kinds of components are mixed in proportion, leaves standstill to remove bubble and obtain mixes liquid silica gel; Then getting a flexible glue skin tiling is placed in square box; Then on this cushion compound, place the plastic sheet of pre-processed band hollow out cavity figure, and on the plastic sheet that mixes liquid silica gel is tiled in square box, be placed in 60 ~ 80 DEG C of bakings and make liquid-state silicon gel be frozen into gel in 1 ~ 2 hour; Finally cushion compound is removed, obtain filling mould tire.
As preferably, the mixed proportion of described silica gel monomers A and flocculating agent B is 2:1 ~ 4:1, thus makes the gelinite in filling mould tire have certain elasticity, and it can be filled in the fine cavity body structure of ceramic chips.
As preferably, described curtain coating ceramic chips, before the aluminium sheet overlaying band locating dowel, aluminium sheet is first laid one deck kalimeris film.
As preferably, described plastic encapsulation bag material adopts polystyrene plastics, thus makes plastic packets envelope have some strength and plastic deformation ability.
Beneficial effect: the present invention compared with prior art, have the following advantages: filling mould mold in this method has certain elasticity and hardness can be filled in the fine cavity body structure of ceramic chips, not cracky again, the fine cavity body structure of shaping multi-layer ceramics is made to have certain precision, keep Ceramic bond intensity and air-tightness, improve lamination efficiency and spatter property; Be not easy breakage thus can reuse simultaneously, save cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the structural representation of fine cavity body structure multi-layer ceramics of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, the gel filled body of a kind of laminating prepares the method for fine cavity body structure multi-layer ceramics, first liquid-state silicon gel A and B two kinds of components (i.e. silica gel monomers A and flocculating agent B) are mixed according to certain ratio (2:1 or 4:1), leave standstill 10 minutes, remove bubble.Then, after being cleaned up by flexible glue skin, spread out and be placed in a square box, bottom surface is paved.Process in advance hard plastic sheet with fine cavity body structure hollow out figure is lain on cushion compound.On the hard plastic sheet that the liquid-state silicon gel mixture mixed in advance is paved in square box, and be placed in baking 1-2 hour in 60-80 DEG C of baking oven, it is made to become curdled appearance to form gel, finally remove cushion compound below, namely obtain by with hollow out figure hard plastic sheet and be laid in the filling mould tire 3 that the gel on it forms.
By curtain coating ceramic chips 2 through punching, printing, the technique such as to begin to speak, make its surrounding have lamination locating hole, and inside has hollow out cavity figure.Then being with aluminium sheet 1 upper berth one deck kalimeris film of locating dowel, (kalimeris film is a kind of PET mould release membrance used in multi-layer ceramics casting technology, a kind of organic film generally applied in the sector), and according to order from bottom to top, curtain coating ceramic chips 2 is folded thereon, and make locating hole on ceramic chips 2 through the locating dowel on aluminium sheet 1, with this, each piece of ceramic chips 2 is fixed.And on the ceramic chips 2 on most top layer superimposed above-mentioned filling mould tire 3 (the hollow out figure of this filling mould tire 3 is identical with the superiors ceramic chips 2), and make both hollow out figures completely overlapping; Then a soft rubber cushion 4 is being covered topmost.Be placed in the polystyrene plastics packaging bag with some strength and plastic deformation ability to encapsulate through vacuum, lamination, obtains the multi-layer ceramics with laminated construction.After lamination terminates, filling mould tire 3 is taken off from porcelain belt surface, clean in porcelain attached cavity the broken gel particle of filling with hairbrush gently, obtain the fine cavity body structure of multi-layer ceramics with certain formed precision.
Gel on mould tire 3 is filled under the effect of the pressure by the hollow out figure on hard plastic sheet in lamination process, initiatively be filled into and need in the fine cavity body structure of filling in its lower ceramic chips 2, after removing pressure, there is a small amount of gelinite to remain in cavity, fill mould tire 3 and can continue on for the shaping of next folded multi-layer ceramics.This filling mould tire 3 smooth surface is flexible, hardness is moderate, ensure that it can be filled in the fine cavity of porcelain band under pressure smoothly, although after removing pressure, the gel chip being filled into inside cavity can continue to remain in cavity, but can not adhesion or pollute porcelain band and surface metalation figure.After taking off mould tire, can clean gently with hairbrush, residual gel chip can be removed.This multi-layer ceramics top layer hard plastic sheet has certain hardness, can ensure that lamination process top layer porcelain band has good shape under its protection.This processing method is simple, and formed precision is higher, and shaping any cavity geometry, can ensure Ceramic bond intensity and air-tightness, improves lamination efficiency and spatter property, saves cost of manufacture.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
