[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0014] As shown in the attached Figure 1-2 figures, the present utility model provides a production tooling for two water jacket sand cores in one mold, including a bottom frame 1. A lower mold 2 is arranged on the top of the bottom frame 1. Two cylinder piston blocks 3 are arranged on the top of the lower mold 2. A cylinder ejector block is fixedly installed on one side of each of the two cylinder piston blocks 3. An upper mold 4 is arranged on the top of the lower mold 2. A sand shooting plate 5 is arranged on the top of the upper mold 4. An air blowing plate 6 is arranged on the top of the sand shooting plate 5. An upper top plate 7 is arranged on the top of the air blowing plate 6. Cylinder mounting plates 9 are fixedly installed on both sides of the lower mold 2. Cylinders 8 are fixedly installed on the outer sides of the cylinder mounting plates 9.
[0015] The output shaft of the cylinder 8 is in transmission connection with the cylinder piston block 3.
[0016] The lower mold 2 is adapted to the upper mold 4.
[0017] The specific implementation method is as follows: when using the utility model, the cylinder 8 drives the cylinder movable block 3 and the cylinder extraction block, so that the device can open the mold horizontally and realize the cylinder side extraction structure, which allows the sand core to be pulled out of the device while lying flat, thereby avoiding the problem that the core head of the sand core is directed upward and breaks during the mold opening process. Then, by providing two cylinder movable blocks 3 and cylinder extraction blocks, the device can make two sand cores at the same time, thereby improving production efficiency. Then, the material gem sand (50 / 100 mesh): silica sand (50 / 100 mesh) = 70%: 30% in the prior art is changed to silica sand (50 / 100 mesh) 100%, thereby improving the quality of the sand core and avoiding damage to the sand core during the production process. This allows the utility model to produce two water jacket sand cores at the same time, with an efficiency increase of 100%, and then avoids the problem that the core head of the sand core is directed upward and breaks during the mold opening process. The product yield rate is greatly improved. Compared with the original technology, the yield rate is higher, thereby making the actual use effect of the utility model better.
[0018] Working principle of this utility model:

Then, the problem of the sand core head being upward and breaking during the mold opening process is avoided, and the product yield rate is greatly improved. Compared with the original technology, the yield rate is higher, so the actual use effect of the utility model is better.
