Description

A kind of novel die of extruded ceramic thin plate
Technical field
The utility model relates to pottery plate processing unit (plant) field, is specifically related to a kind of novel die of wet-method extrusion forming ceramic thin plate.
Background technology
Traditional pottery plate is all that thickness is ceramic slab more than 18mm, and its processing unit (plant) is a kind of extrusion molding pottery board mold as Chinese utility model patent CN201220503442.4 discloses, and comprises connected successively base plate, middle baffle plate, formed frame; Described base plate, formed frame and middle baffle plate all have the hollow cavity of flare, and each hollow cavity is communicated with the horn-like dies cavity of formation successively, and described horn-like dies cavity cross-sectional sizes reduces gradually from base plate to formed frame; Described middle baffle plate has multiple, be respectively baffle plate in baffle plate in first, second ..., baffle plate in N, N is more than or equal to 2 natural number; In described base plate and first, between baffle plate, be provided with tune trowel, and backplane interface width is consistent with extruder extrusion width; The cross section of described formed frame is rectangle.The tapering of the hollow cavity of described base plate is 30 °-38 °, and the tapering of the hollow cavity of baffle plate is 25 °-32 ° in first, and the tapering of the hollow cavity of baffle plate is 20 °-25 ° in second, and the tapering of the hollow cavity of formed frame is 0 °-5 °; In N, the tapering of the hollow cavity of baffle plate is less than the tapering of the hollow cavity of baffle plate in N-1, and is greater than the tapering of the hollow cavity of formed frame.From described base plate, first baffle plate in baffle plate, second ..., in N baffle plate to formed frame, the width exporting under the former pug is than connected the latter's the large 10-20mm of pug interface width, be the adjacent highly step for 5-10mm that is provided with between the two, N is more than or equal to 2 natural number.The external form width of described base plate, middle baffle plate and formed frame successively decreases.
Because Water conservancy diversion core pole pair pug plays the effect of water conservancy diversion, be absolutely necessary, so the width of the corresponding pottery of extrusion plate thickness can not arbitrarily dwindle, and consider the situation such as the flowing space and the pre-distribution of internal stress that reserved pug is extruded, make this utility model structurally present obvious limitation, the i.e. extrusion molding of this class formation pottery board mold can only be produced the ceramic slab of the above thickness of 7mm, and it is thick seldom to approach 7mm, and cannot produce the ceramic thin plate of the following thickness of 7mm, and on market, also seldom there is an extruded ceramic thin plate of the following thickness of 7mm, be mainly because compared with thin extruded ceramic plate easily because the factors such as internal stress produce distortion, even stress is concentrated and is caused cracking, have a strong impact on intensity and the service life of ceramic thin plate.
But due to ceramic thin plate have that material usage is few, cost is low, frivolous, save the interior space and be convenient to the advantages such as transport, in recent years, on market, there are some ceramic thin plates, some thickness is 4-5mm, but most thickness is about 5-7mm.The technique of this ceramic thin plate of existing production roughly has two kinds, and one is to burn till with the direct dry-pressing formed rear glazing of powder; Another kind is that wet base is extruded the crude green body of thickness 10mm left and right, then after 2-3 roll-in, cutting, is dried, then burns till through glazing.Clearly, the operation of these two kinds of production technologies is loaded down with trivial details, and production efficiency is low; And, these two kinds of production technologies due to operational characteristic determine that it produces ceramic thin plate be all plane form, and cannot produce the ceramic thin plate with grooves such as dovetail grooves, so in actual use, paste the ceramic thin plate of plane form if adopt wet method, can often occur from situations such as wall even come off because the adhesion of ceramic thin plate and Binder Materials is not enough, bring many troubles.
Given this, this case inventor further investigate the problems referred to above, then has this case to produce.
Utility model content
