Abstract
The utility model discloses a large -scale ceramic member mould for sintering, burn the board including holding, arrange in hold burn the board on with the pad of the same material of ceramic member burns the board, hold burn the board with fill up between the fever board, reach all be provided with supplementary shrink layer on the pad fever board, supplementary shrink layer is the corundum sand bed, it is not less than to fill up the plane size of burning the board ceramic member is rather than the contact surface of contact, it is greater than 25mm to fill up the fever plate thickness. The utility model discloses outstanding effect does: burn board and corundum sand bed through increasing to fill up for fill up to burn board and ceramic member syntropy shrink simultaneously in sintering process, ceramic unburned bricks burn the board and are in position static relatively all the time for filling up, and fill up and burn the board and burn the board and take place frictional resistance with holding, thereby improve the qualification rate of sintering spare.
Description
Technical field
This utility model relates to a kind of large size ceramic part sintering mould。
Background technology
Domestic general product loading of kiln mode is to be placed directly in load bearing board by ceramic green, but owing to green compact shrink in sintering process, and load bearing board itself expands, there is frictional force between such green compact and load bearing board to hinder, can because of its ceramic green shrink up and down asynchronous, cause little deformation big below above ceramic member, time serious, can cause that product ftractures。, owing to zirconium oxide crystalline phase exists transformation temperature at about 1200 DEG C, the transformation of monocline Tetragonal in opposite directions can be there is at these temperature spot parts in the particularly sintering of yttrium stable zirconium oxide pottery, and with the change in volume of 3 ~ 5%。The contraction of 1200 DEG C of transformation temperatures can aggravate to rub cause shrink inconsistent phenomenon, so large-scale zirconium oxide ceramic component is easier to produce the phenomenon of cracking in sintering process。
Utility model content
In view of prior art exists drawbacks described above, the purpose of this utility model is in that to provide a kind of large size ceramic part sintering crack resistence mould。
The purpose of this utility model, will be achieved by the following technical programs:
Large size ceramic part sintering mould, plate is burnt including load bearing board, the pad that is placed on load bearing board material identical with described ceramic member, described load bearing board and described pad burn between plate and described pad burns and is provided with auxiliary shrinkage layer on plate, described auxiliary shrinkage layer is emery sand, the planar dimension that described pad burns plate is not less than the contact surface that described ceramic member is in contact with it, and described pad burns plate thickness more than 25mm。
Preferably, the tiling of described emery sand is placed on described load bearing board and described pad burning plate。
The prominent effect of this utility model is: burn plate and emery sand by increasing pad, make pad burn plate to shrink in the same direction in sintering process with ceramic member simultaneously, ceramic green burns plate relative to pad and is in the position of geo-stationary all the time, and pad burning plate and load bearing board generation frictional resistance, thus improving the qualification rate of sintered part。
Hereinafter just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are more readily understood, grasp。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
This utility model discloses a kind of large size ceramic part sintering mould, and during sintering, described ceramic member 1 is ceramic green, shown in Fig. 1, burns plate 2 including load bearing board 4, the pad that is placed on load bearing board 4 material identical with described ceramic member。Described identical material refers to ceramic member to be same material and is same batch of powder。
Described load bearing board 4 and described pad burn between plate 2 and described pad burns and is provided with auxiliary shrinkage layer on plate 2, and described auxiliary shrinkage layer is emery sand 3。Particularly referring to, the tiling of described emery sand 3 is placed in described load bearing board 4 and described pad burns between plate 2, and described pad burns on plate 2。Contraction is assisted in arranging of emery sand 3 on the one hand, is conducive to the discharge of cold stage moisture and organic additive on the other hand。
During due to sintering, described ceramic member 1 is placed in described pad and burns on plate 2, and the planar dimension that described pad burns plate 2 is not less than the contact surface that described ceramic member 1 is in contact with it。The pad shunk by placing one block of auxiliary green compact between ceramic member 1 and load bearing board 4 burns plate 2, solves ceramic member 1 and causes deformation and cracking because of the frictional resistance between load bearing board 4。
Described pad burns plate 2 thickness more than 25mm, and the intensity to ensure pad burning plate 2 will not crack because of frictional resistance。So making pad burn plate 2 and ceramic member 1 shrinks simultaneously in the same direction, ceramic member 1 burns plate 2 relative to pad and is in the position of geo-stationary all the time, thus at utmost eliminating friction, improves the qualification rate of sintered part。
This utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of being formed, all falls within protection domain of the present utility model。
