[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] like Figures 1-2 As shown, the technical solution adopted by this utility model is as follows: a turbine pump housing casting cooling device includes a base 1, a lower mold 2 is fixedly installed on the top of the base 1, an upper mold 10 is provided above the lower mold 2, and a rotating shaft 4 is rotatably installed in the horizontal direction. A drive mechanism for driving the rotating shaft 4 to rotate is provided on the base 1.

[0020] The drive mechanism includes a motor 3, a support plate 14 is fixedly mounted on the base 1, the motor 3 is fixedly mounted on the support plate 14, and the output shaft of the motor 3 is coaxially and fixedly connected to one end of the rotating shaft 4. Two supports 5 are fixedly mounted on the base 1, and the rotating shaft 4 rotates through the two supports 5.

[0021] Two connecting sleeves 13 are fixedly fitted onto the outer surface of the rotating shaft 4. Each connecting sleeve 13 is equipped with a spring rod 6, which consists of a telescopic rod and a spring. The spring inside the spring rod 6 is always in a stretched state. The spring rod 6 is prior art and will not be described in detail in this solution.

[0022] Two slide rails 11 are fixedly installed on the top inner wall of the base 1. The two slide rails 11 are arranged symmetrically. Each slide rail 11 is composed of a vertical first guide groove 111 and an inclined second guide groove 112 connected together. The connection between the first guide groove 111 and the second guide groove 112 is a smooth arc.

[0023] Two connecting blocks 9 are fixedly installed on the upper mold 10. The two connecting blocks 9 are symmetrically arranged on both sides of the upper mold 10. The connecting blocks 9 correspond one-to-one with the slide rail 11 and one-to-one with the spring rod 6. Each connecting block 9 is both limited and slidably installed in the corresponding slide rail 11, and is also connected to the corresponding spring rod 6 through the transmission component.

[0024] The transmission member comprises a connecting shaft 8, the connecting shaft 8 is fixedly arranged on the connecting block 9, the outer surface of the connecting shaft 8 is rotatably sleeved with the sleeve 7, and the sleeve 7 is fixedly connected with one end of the spring rod 6 which is not connected with the connecting sleeve 13.

[0025] The upper mold 10 is provided with a liquid injection hole 12 at the top, and the interiors of the upper mold 10 and the lower mold 2 are both provided with cooling channels (not shown in the figure), and the two ends of the cooling channels are fixedly connected with water inlet pipes and water outlet pipes respectively.

[0026] Working principle: when in use, melt metal liquid is injected through the liquid injection hole 12, and then cooling water is introduced from the water inlet pipes of the upper mold 10 and the lower mold 2, so as to cool the metal liquid, and the cooling water flows out from the water outlet pipes after passing through the cooling channels. The cooling water can accelerate the cooling of the metal liquid, so as to quickly form the turbine pump shell.

[0027] After the cooling is completed, the motor 3 is started, the output shaft of the motor 3 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the spring rod 6 to rotate around the central axis of the rotating shaft 4 through the connecting sleeve 13, and the spring rod 6 drives the connecting shaft 8 and the connecting block 9 to move upwards through the sleeve 7, so that the connecting block 9 moves upwards along the first guide groove 111. During this period, the spring rod 6 is appropriately contracted, until the connecting block 9 drives the upper mold 10 to completely separate from the lower mold 2, and then the cooled turbine pump shell can be taken out.

[0028] If it is needed to clean the interiors of the upper mold 10 and the lower mold 2, the motor 3 is continuously rotated after the above process, so that the connecting block 9 slides to the second guide groove 112, the connecting block 9 drives the upper mold 10 to rotate and overturn by a certain angle, so that the mold cavity opening of the upper mold 10 is inclined outward, so as to facilitate the cleaning of the staff, and avoid the influence of the residual impurities in the interiors on the casting quality.

[0029] In addition, the spring rod 6 always maintains a stretched state during the above process, but the length of the stretching changes with the change of the rotating angle, so that the spring rod 6 can maintain the descending speed of the upper mold 10 during the descending process, and avoid the knocking of the upper mold 10 to the lower mold 2.

[0030] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
