Compared with the prior art, the structure of the utility model is simple and reasonable, the molding process is stable and reliable, the electric insulation ceramic body molded with the utility model has good uniformity of the inherent quality and the size, the subsequent burning process is simple, and the product burning qualification rate is extremely high, thus being favorable for the forming of mass production.
Description
Technical field
The utility model relates to a kind of ceramic member mould, particularly relates to the automatic press-moulding die of a kind of electric insulation ceramics spare.
Background technology
The manufacturing technique method of traditional electric insulation ceramics spare mainly contains hot-injection molding and extrusion moulding, the hot-injection molding method will be mixed into slurry with ceramic powder and paraffin etc. earlier, because slurry viscosity is higher, the bubble of carrying secretly in the slurry is difficult to discharge, and causes the immanent structure of product inhomogeneous; After moulding, biscuit of ceramics needs for a long time dewaxing at low temperatures, because electric insulation ceramics spare wall is thicker, base substrate easily causes defectives such as cracking, a big gun in dewaxing process, thus be difficult to satisfy production requirement, and also the organic gas of discharging also pollutes the environment.Extrusion moulding is the process that the electric insulation ceramics industrial production is widely applied, during production, ceramic raw material is made moisture and slurry adhesive, through dewater, outgas, extrude, after the operation such as drying, making needed ceramic member shape through Vehicle Processing or after cutting; This production method is in dry and Vehicle Processing process, and process period is long, processing cost is high, and production efficiency is lower.
The patent No. is that the patent of CN2563743Y has also disclosed a kind of fuse aluminium oxide ceramics press-moulding die, and every product needed is manually assisted dress mould, depanning during its moulding, is unfavorable for the raising of production efficiency.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of electric insulation ceramics spare automatic press-moulding die for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the automatic press-moulding die of a kind of electric insulation ceramics spare, it is characterized in that, comprise Xia Chong, down towards base, the upper punch that can regulate the center, core rod, have the die cavity cover of wear-resistant liner, described dashing down is located at down on base, and and upper punch between leave certain space, in described core rod is located at down and is dashed, and by dash down and upper punch between the space be through to upper punch, described die cavity cover be sheathed on down dash and upper punch between the space outside, and with dash down and upper punch is close to, promptly form die cavity.
Described dashing down by setscrew nut one is connected and fixed towards base with following.
The upper end of described upper punch is provided with and the fixing setscrew nut two of usefulness of mo(u)ldenpress seaming chuck.
Described setscrew nut two is provided with the torsion hole.
Compared with prior art, the utility model is simple and reasonable, and moulding process is reliable and stable, adopt the electric insulation ceramics base substrate of the utility model moulding, the high conformity of inherent quality and size, follow-up firing process is simple, the product sintering qualified rate is high, helps forming mass production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: dash under the 1-, towards base, 3-can regulate the upper punch at center under the 2-, 4-core rod, 5-die cavity cover, 6-die cavity, 7-setscrew nut one, 8-setscrew nut two, 9-wear-resistant liner, 10-torsion hole.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the automatic press-moulding die of a kind of electric insulation ceramics spare, it is characterized in that, comprise dash down 1, down towards base 2, the upper punch 3 that can regulate the center, core rod 4, have the die cavity cover 5 of wear-resistant liner 9, dashing 1 under described is located at down on base 2, and and upper punch 3 between leave certain space, described core rod 4 is located at down and is dashed in 1, and by dash down 1 and upper punch 3 between the space be through to upper punch 3, described die cavity cover 5 be sheathed on down towards and upper punch between the space outside, and with dash down 1 and upper punch 3 be close to, promptly form die cavity 6.
Be connected and fixed towards base 2 with following by setscrew nut 1 towards 1 under described; The upper end of described upper punch 3 is provided with and the fixing setscrew nut 28 of usefulness of mo(u)ldenpress seaming chuck; Described setscrew nut 28 is provided with torsion hole 10.
The compacting of electric insulation ceramics ring:
Get the rod iron of hardness HRC 〉=45, make mold core through grinding, polishing, the size of its diameter is set size according to the characteristic of ceramic powder and the specification of product.The inwall of die cavity has wear-resistant liner, and this wear-resistant liner material is can be zirconia ceramics or carbide alloy, and wear-resistant liner thickness is six millimeters to 12 millimeters, is set in the inboard of die cavity by the method for joining firmly.
Upper punch is fixed on by the setscrew nut that has the torsion hole on the seaming chuck of mo(u)ldenpress, transmits downward pressure; Dash down and be fixed on be connected with the mo(u)ldenpress push-down head following on base, transmit upward pressure by setscrew nut; Core rod is fixed on the center ram, transmits the demoulding action of floating.
During use, add die cavity automatically by the feeding device of automatic moulding press through prefabricated ceramic powder, add ceramic powder after, upper punch and dash last push-down head by the automatic moulding press down and transmit bidirection press and push powder.After the compacting, the demoulding action that the seaming chuck transmission of upper punch by the automatic moulding press makes progress, core rod is by the downward demoulding action of center ram transmission, die cavity is by the downward demoulding action of automatic moulding press, finish the automatic demoulding of ceramic member, and ceramic member is released shaping area by ejecting device, finish the circulation of an automatic moulding compacting.Briquetting pressure is set at 80 to 90 MPas by the mo(u)ldenpress pressure regulating system according to technological requirement, and each circulation can be finished in 7.5 seconds, and output per day reaches more than 8,000, and the moulding qualification rate reaches 98%.
