Abstract
The utility model belongs to the technical field of a sand mold, and particularly relates to an AZS (Al2O3-ZrO2-SiO2) runner brick sand mold. The sand mold comprises a bottom plate, a side frame and a top plate, wherein the side frame is arranged on the bottom plate, the top plate is arranged on the side frame, a sand core is arranged on the bottom plate and consists of two landing legs, steps are arranged on the tops of one opposite sides of the landing legs, supporting plates are arranged on the steps, a clearance is reserved between each supporting plate and the step and is filled with a filling section, and the filling section and the supporting plates are flush with the tops of the landing legs. When the AZS runner brick sand mold is adopted for pouring, the excellent deformability of the sand core can be guaranteed through the filling section, and the pass percent of the runner bricks can be increased to 80% from originally 20%.
Description
technical field
The utility model belongs to sand mold technical field, is specifically related to a kind of AZS runner brick sand mold.
background technology
AZS runner brick is because structure is special, adopt general sand mold preparation method, after casting because AZS liquation is by 1800 DEG C of cooling solidification processes, roughly to produce 13% volume contraction, but due to sand mold used in current sand mold as shown in Figure 1, comprise base plate 1, frame 2 and top board 3, frame 2 is arranged on base plate 1, top board 3 is arranged on frame 2, top board 3 is provided with rising head 4, base plate 1 is provided with core 11, core 11 is global design, the shrinkage factor of core 11 is smaller, deformability is bad, easily generation mechanical stress causes in the rear runner brick of casting and occurs crackle, cause brick material to scrap.
summary of the invention
The AZS runner brick sand mold that provides a kind of deformability good is provided the purpose of this utility model.
In order to realize above object, the utility model by the following technical solutions:
A kind of AZS runner brick sand mold, comprise base plate, frame and top board, frame is arranged on base plate, and top board is arranged on frame, and base plate is provided with core, core comprises two legs, the top of the relative side of leg is respectively equipped with a step, is placed with gripper shoe on step, between gripper shoe and step, leaves space, in space, be filled with filled section, filled section, gripper shoe are concordant with the top of leg.
The width in described space is 0.5-2cm.
The material of described filler can be selected the good material of conventional shrinkage, for example common sawdust or carton board.
Described top board is provided with rising head.
In order to save material, leg can be made as hollow.
The material of leg and gripper shoe is white fused alumina.
The overall sand mold in original sand mold is carried out packet design by the utility model, change former integral sand core into three parts, comprise two hollow legs, be provided with a step at the top of leg, on step, place gripper shoe and make gripper shoe and step between leave a fixed gap, filled section is set in space, ensures that filled section, gripper shoe are concordant with the top of leg, the overall exterior shape that leg, gripper shoe, filled section are formed is the same with original integral sand core.
Like this, adopt the utility model in when casting, filled section has ensured that core has good deformability, and the qualification rate that makes runner brick rises to 80% by original 20%.
brief description of the drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
detailed description of the invention
AZS runner brick sand mold as shown in Figure 2, comprise base plate 1, frame 2 and top board 3, frame 2 is arranged on base plate 1, top board 3 is arranged on the top of frame 2, top board 3 is provided with rising head 4, base plate 1 is provided with core, core comprises leg 5 and leg 51, the top of leg 5 side relative to leg 51 is respectively equipped with a step, on step, be placed with gripper shoe 7, between gripper shoe 7 and step, leave the space of 0.5-2cm, in space, be filled with respectively filled section 6 and filled section 61, filled section 6, filled section 61, gripper shoe 7 and leg 5, the top of leg 51 is concordant, make leg 5, leg 51, gripper shoe 7, filled section 6, the overall exterior shape that filled section 61 forms is the same with original integral sand core.
The overall sand mold in original sand mold is carried out packet design by the utility model, change former integral sand core into leg 5, leg 51, gripper shoe 7, filled section 6, filled section more than 61 parts, the good material of conventional shrinkage is selected in filled section 6, filled section 61, while making the utility model casting, filled section 6, filled section 61 have ensured that core has good deformability, has improved the qualification rate of product.
