Description

Large-scale ceramic forming exhaust mold core

Technical Field

The utility model relates to a mold core preparation field, concretely relates to extensive ceramic forming exhaust mold core.

Background

The core, as the name implies, refers to the precision part used for the critical operation of the central part of the mold. The common structure of the mold core is extremely complex, the processing difficulty is very large, the manufacturing cost is very high, and the labor expenditure for manufacturing is greatly higher than that of the material. The selection of the die core material is also directly related to the manufacturing cost of the die and the service life of the die, for the ceramic forming die core, gas in the ceramic manufacturing process needs to be discharged, a common gas discharging die needs 4 times of gas discharging to finish one-time pressing, the gas discharging time of a press needs to be adjusted longer, the punching times per minute cannot be increased quickly, 800X800-2W can only press 3.3-3.5 times, the stability is poor, the gas discharging and pressing parameters need to be checked and adjusted frequently in the operation of the press, defective bricks such as layering and the like can appear once careless, and the layering defect of a brick blank can easily appear; after the brick is used for 3-5 ten thousand times, the exhaust holes are easy to enlarge due to the exhaust mold core, and the bottom of the brick blank has a convex point phenomenon; moreover, the compact change of the green body is large, and the brick surface cracking defect is easily generated; the phenomenon of rod nail lifting is easily caused due to uneven brick bottom, and the rod replacement period is shortened; the deformation degree of the brick is difficult to adjust due to the fact that the blank body is dense and changes greatly

In the structure, air in the ceramic can be extruded into the exhaust holes through the vertical through seams and the transverse through seams of the adhesive film layer under the action of pressure and is exhausted after entering the exhaust pipe, so that powder can be pressed together more tightly, and meanwhile, under the layer-by-layer blocking action of the vertical through seams, the transverse through seams and the exhaust holes of the adhesive film layer, the powder is prevented from overflowing to form bulges, and the forming quality of a green brick is improved.

Has the advantages that: 1. the press has high press forming efficiency, the high-efficiency low-carbon exhaust grinding press can complete one-time pressing only by exhausting for 2-3 times, the exhaust time of the press is greatly shortened, the punching times per minute can be increased, the press can only press for 4.0-4.5 times at 800X800-2W, the stability is good, and the operation of the press does not need to adjust the exhaust and pressing parameters;

2. the quality of the formed brick is high, the layering defect of the high-efficiency low-carbon exhaust grinding brick blank is basically avoided, the bottom of the brick blank is good after the brick blank is used for 50-60 ten thousand times, and the blank body is compact and uniform;

3. the high-efficiency low-carbon exhaust mill is suitable for wide fluctuation range of powder, and the common exhaust die has higher requirements on parameters such as moisture, fluidity, particle size distribution and the like of the powder;

4. the brick surface cracking defect is basically avoided; the brick bottom is relatively flat, the loss caused by the stick is less, the stick changing period is prolonged, and the deformation degree of the brick is relatively adjusted because the green body is compact and uniform; the green body is more uniform in compactness, and the deformation degree of the brick is relatively adjusted;

5. the service life is long, 50-60 ten thousand times of renovation and maintenance can be carried out, and the ordinary exhaust mill needs to be renovated and maintained after being used for 3-5 times.
