[0005] A mold gantry, wherein a pouring cup groove is provided in the mold gantry;

[0006] A pouring cup is fixed in the pouring cup groove. A pouring port is provided at the bottom of the pouring cup. A mounting groove is provided in the pouring port. A ceramic filter block is fixed in the mounting groove. The ceramic filter block is clamped and positioned by a clamping member.

[0007] Furthermore, the mounting groove is arranged at a corner of the bottom of the beaker.

[0008] Furthermore, one side of the pouring cup has a notch, the clamping member is a side module, the side module matches the notch, and the back of the side module is fixedly connected to a cylinder.

[0009] Furthermore, the installation groove is a square groove, and the ceramic filter block matches the square groove.

[0010] Furthermore, the bottom surface height of the pouring cup gradually decreases, and the pouring cup is fixedly connected to the pouring cup groove through screw holes on the front area of ​​the bottom surface.

[0011] Furthermore, the opening area of ​​the pouring port has a V-shaped guide groove.

[0012] The beneficial effects of the utility model are:

[0013] First, the pouring cup filtering device can filter larger impurities through the through holes on the ceramic filter block in the pouring cup, so that they will not flow into the mold cavity, reducing the possibility of impurities remaining in the mold or the product, thereby effectively improving the quality of the cast product;

[0014] Second, the ceramic filter block can be purchased directly on the market, its cutting is simpler, the preparation cost is low, and it can be quickly replaced after casting, ensuring that the filter device always maintains the best filtering effect;

[0015] Third, through the role of the side module, after being pressed by the cylinder, the ceramic filter block can be quickly fixed, and the pouring cup can be closed while fixing the filter block to prevent the molten metal from flowing out of the side gap. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] See also Figure 1-3 A bottom-casting mold pouring cup 3 filtering device is shown, comprising:

[0023] A mold gantry 1, wherein a pouring cup 3 slot 2 is provided in the mold gantry 1; the mold gantry 1 is a part of the casting mold;

[0024] A pouring cup 3 is fixed in the pouring cup 3 groove 2. A pouring port 4 is provided at the bottom of the pouring cup 3. A mounting groove 5 is provided in the pouring port 4. A ceramic filter block 6 is fixed in the mounting groove 5. The ceramic filter block 6 has multiple layers of densely distributed through holes. The ceramic filter block 6 is clamped and positioned by a clamping member.

[0025] The process of using the utility model is as follows: first, the pouring cup 3 is installed and fixed in the pouring cup 3 groove 2 of the mold gantry 1, and then the mold gantry 1 is installed on the casting mold. When the pouring cup 3 is casting the product, the molten metal is poured from the pouring cup 3. After the molten metal is poured, it will pass through the ceramic filter block 6 and then enter the pouring port 4. Since a number of through holes are provided on the ceramic filter block 6, impurities in the molten metal can be filtered to prevent impurities from entering the cavity of the casting mold. After the product in the casting mold is cooled and formed, the clamping piece used to clamp the ceramic filter block 6 is removed, and the ceramic filter block 6 is taken out for replacement. Since the ceramic filter block 6 is small in size and low in cost, it will hardly increase the cost of the cast product. Overall, the quality of the cast product is better, and the reduced scrap rate will also reduce the casting cost.

[0026] Further, the mounting groove 5 is arranged at a corner of the bottom of the beaker. Specifically, in the utility model, the mounting groove 5 is arranged at the lower right corner of the bottom of the beaker, so that the molten metal directly flows into the mold from the lower right corner of the beaker.

[0027] Furthermore, the pouring cup 3 has a notch 7 on one side, and the pressing member is a side module 8, which matches the notch 7, and the back of the side module 8 is fixedly connected to an oil cylinder. Specifically, when the ceramic filter block 6 of the utility model is pressed, it is pressed by the side module 8, and the side module 8 is fixed to an oil cylinder, and after being pressed, it can just match the notch 7 of the beaker.

[0028] Further, the installation slot 5 is a square slot, and the ceramic filter block 6 matches the square slot. Specifically, the installation slot 5 of the utility model is connected to the ceramic filter block 6, and the square ceramic installation slot 5 is more convenient and stable when positioned by the side module 8.

[0029] Furthermore, the bottom height of the pouring cup 3 is gradually reduced, and the pouring cup 3 is fixedly connected to the pouring cup 3 groove 2 through the screw hole 10 on the front area of ​​the bottom. Specifically, since the bottom height of the beaker is gradually reduced, the molten metal can flow in a lower direction. In addition, since the front area of ​​the bottom of the pouring cup 3 is thicker, the screw hole 10 can be processed thereon, so that the pouring cup 3 can be better fixed on the mold gantry 1.

[0030] Furthermore, the opening area of ​​the pouring port 4 has a V-shaped guide groove 9. The V-shaped guide groove 9 allows the molten metal to enter the pouring port 4 more smoothly, and the molten metal is not likely to remain on the bottom surface of the pouring cup 3.

[0031] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
