Abstract

The utility model discloses a ceramic mold elastic lower mold core. In addition to a lower mold core, the ceramic mold elastic lower mold core further comprises a substrate and bearing springs. Three to six rows of bearing springs are arranged. Three to eight bearing springs are in each row, and the rows are arranged to be parallel to each other. One end of a bearing spring is welded on the upper surface of the substrate, while the other end is welded on the lower surface of the lower mold core. The substrate is arranged on a base of a ceramic brick machine. The ceramic mold elastic lower mold core provided by the utility model has the advantages of simple structure. When the ceramic mold elastic lower mold core is in use, the bearing springs establish an elastic buffer area between the substrate and the lower mold core. When the ceramic brick machine pushes an upper mold core to extrude ceramic powder materials, the lower mold core makes appropriate adjustment and maintain overall stable under the action of the bearing springs, thus the defect of uneven ceramic embryo density is solved, and the manufacturing cost is reduced by more than 50%. The ceramic mold elastic lower mold core is suitable for all ceramic molds.

Description

Ceramic die elasticity lower mold core

Technical field the utility model relates to a kind of lower mold core, the lower mold core of especially on ceramic die, using with spring.

The background technology ceramic die comprises upper mold core, lower mold core and frame, and they constitute the extrusion modling space of ceramic idiosome jointly.Ceramic brick press is when promoting upper mold core extruding ceramic powder, because the issue of ceramic powder can not be fully evenly, therefore the ceramic green density of compacting is uneven.In the drying and sintering procedure of back, deformation can take place in the ceramic idiosome of density unevenness, directly influences the qualification rate of ceramic product.In order to solve the uneven defective of ceramic green density, generally adopt the isostatic mold core now.

Chinese patent CN2267142 number disclosed " the equivalent ceramic die of pressing " patent (application number: 96237427.X); Design the plastic emitting support on the basis of existing technology, support is arranged in the working hole, the die cavity between the embedding of work colloid, filling support outer wall and the work hole wall; And the plug on support endoporus and top thereof forms pressure oil cavity; Such structure has not only increased the contact area of work colloid and matrix greatly, and hydraulic oil has pressuring action to the work colloid of the hole wall of working.The weak point of this patent is: the same with other isostatic mold core, and exist processing technology complicated, long processing time, the high deficiency of manufacturing cost.

The purpose of summary of the invention the utility model is exactly that a kind of ceramic die elasticity lower mold core simple in structure will be provided, and is solving the uneven defective of ceramic green density simultaneously, and simplified structure reduces cost.

In order to achieve the above object, the ceramic die elasticity lower mold core that the utility model provides also has substrate and load bearing spring except comprising lower mold core; Wherein, load bearing spring has three to six rows, and every row has three to eight; Be between row and row and be arranged in parallel; Such structure and layout make load bearing spring assurance lower mold core when work can do suitable adjustment and keep steadily whole, and load bearing spring quantity is then waste too much, and load bearing spring quantity then influences stable very little; Load bearing spring one end is welded on upper surface of base plate, and the other end is welded on the lower surface of lower mold core; Substrate is placed on the pedestal of ceramic brick press.When the utility model uses; Load bearing spring is set up the elastic buffer district between substrate and lower mold core; Make ceramic brick press when promoting upper mold core extruding ceramic powder; Lower mold core can be done suitable adjustment and keep steadily whole under the effect of load bearing spring, thereby solves the uneven defective of ceramic green density.

The ceramic die elasticity lower mold core that the utility model provides has positive effect: except comprising lower mold core, also have substrate and load bearing spring, wherein; Load bearing spring has three to six rows, and every row has three to eight, is between row and row to be arranged in parallel; Load bearing spring one end is welded on upper surface of base plate; The other end is welded on the lower surface of lower mold core, and substrate is placed on the pedestal of ceramic brick press, and is simple in structure; Load bearing spring is set up the elastic buffer district during use between substrate and lower mold core; Make ceramic brick press when promoting upper mold core extruding ceramic powder; Lower mold core can be done suitable adjustment and keep steadily whole under the effect of load bearing spring; Thereby solve the uneven defective of ceramic green density, can reduce manufacturing cost more than 50%, be applicable to all ceramic dies.

Description of drawings the utility model will combine accompanying drawing to be further described, please referring to accompanying drawing:

The sketch map of accompanying drawing 1 expression the utility model.

Structure shown in the accompanying drawing 1 comprises: upper mold core 1, ceramic powder 2, lower mold core 3, load bearing spring 4, substrate 5, frame 6, pedestal 7.

The ceramic die elasticity lower mold core that specific embodiment the utility model provides also has substrate 5 and load bearing spring 4, wherein except comprising lower mold core 3; Load bearing spring 4 has three to six rows; Every row has three to eight, is between row and row to be arranged in parallel, and such structure and layout make load bearing spring 4 guarantee that when work lower mold core 3 can be done suitable adjustment and maintenance is steadily whole; Load bearing spring 4 quantity are then waste too much, and then influence is stable very little for load bearing spring 4 quantity; Load bearing spring 4 one ends are welded on substrate 5 upper surfaces, and the other end is welded on the lower surface of lower mold core 3; Substrate 5 is placed on the pedestal 7 of ceramic brick press.When the utility model uses; Load bearing spring 4 is set up the elastic buffer district between substrate 5 and lower mold core 3; Make ceramic brick press when promoting upper mold core 1 extruding ceramic powder 2; Lower mold core 3 can be done suitable adjustment and keep steadily whole under the effect of load bearing spring 4, thereby solves the uneven defective of ceramic green density.

The utility model protection domain relates to all changes form recited above.
