[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1A schematic structural diagram of a preferred embodiment of a mold for casting a ball core of a ball valve provided by the utility model; Figure 2 for Figure 1 A front view of a mold for casting a ball core of a ball valve; Figure 3 for Figure 1 A front cross-sectional view of a No. 1 mold in a mold for casting a ball core of a ball valve; Figure 4 for Figure 1 A front view of a feed hopper in a ball core casting mold for a ball valve is shown. A ball core casting mold for a ball valve comprises a support platform 1, a limiting sleeve 2 is fixedly connected to the top of the support platform 1, a lifting block 3 is movably sleeved inside the limiting sleeve 2, a support column 4 is fixedly connected to the side of the lifting block 3, a No. 1 mold 5 is fixedly connected to the bottom of the support column 4, a No. 2 mold 6 is fixedly connected to the top of the support platform 1, a water tank 7 is fixedly connected to the bottom of the support platform 1, a support frame 8 is fixedly connected to the bottom of the support platform 1, a delivery pump 9 is fixedly installed inside the support frame 8, a cooling pipe 10 is fixedly sleeved on the top of the delivery pump 9, a limiting mechanism 11 is arranged on the top of the No. 2 mold 6, and a damping plate 12 is fixedly connected to the top of the No. 2 mold 6, a lifting mechanism 13 is arranged on the bottom of the support platform 1, a sliding ball 14 is movably sleeved on the front of the inner wall of the limiting sleeve 2, a feed hopper 15 is fixedly sleeved on the top of the support column 4, and an auxiliary mechanism 16 is arranged on the bottom of the support platform 1.

[0025] The cooling pipe 10 is fixedly sleeved inside the No. 2 mold 6. The material of the cooling pipe 10 is metal copper material, and one end of the cooling pipe 10 is fixedly sleeved inside the water tank 7. By setting the cooling pipe 10, when the core casting is completed, the delivery pump 9 is started, so that the delivery pump 9 can drive the coolant inside the water tank 7 to flow to the inside of the No. 2 mold 6 through the cooling pipe 10. At this time, the coolant can absorb the heat inside the No. 2 mold 6, and then the coolant after absorbing the heat circulates to the inside of the No. 2 mold 6, thereby achieving the cooling effect of the No. 2 mold 6, avoiding the problem of slow natural cooling of the core, thereby greatly improving the casting efficiency of the core.

[0026] The limiting mechanism 11 includes a positioning groove 111, which is opened on the top of the No. 2 mold 6, and a positioning ring 112 is fixedly connected to the bottom of the No. 1 mold 5, and the positioning ring 112 is adapted to the positioning groove 111; by setting the limiting mechanism 11, when the ball core is cast, the No. 1 mold 5 is lowered, so that the No. 1 mold 5 can drive the positioning ring 112 to be movably sleeved inside the positioning groove 111, thereby achieving the positioning effect of the lowered position of the No. 1 mold 5, thereby avoiding the problem of a large gap between the No. 1 mold 5 and the No. 2 mold 6 when the position of the No. 1 mold 5 is offset, thereby improving the casting quality of the ball core.

[0027] The material of the shock-absorbing plate 12 is rubber material, and the number of the shock-absorbing plates 12 is two; by setting the shock-absorbing plate 12, when the mold is assembled, the shock-absorbing plate 12 can reduce the shock of the descending mold No. 1 5, thereby avoiding the problem of the mold No. 1 5 colliding with the top of the mold No. 2 6 when it descends quickly, thereby improving the protective effect of the mold.

[0028] The lifting mechanism 13 includes a rotating motor 131, which is fixedly installed at the bottom of the support platform 1. A threaded column 132 is fixedly connected to the output shaft of the rotating motor 131, and the threaded column 132 is threadedly sleeved inside the lifting block 3. By setting the lifting mechanism 13, when the mold is assembled and fixed, the rotating motor 131 is started, so that the rotating motor 131 can drive the lifting block 3 to move up and down through the threaded column 132, that is, drive the No. 1 mold 5 to move up and down, so that the No. 1 mold 5 can be tightly squeezed on the top of the No. 2 mold 6, thereby achieving the combined fixing effect of the mold.

[0029] There are several sliding balls 14, which are evenly distributed on the front side of the inner wall of the limiting sleeve 2. By setting the sliding balls 14, when the mold assembly is fixed, the sliding balls 14 can limit the position of the lifting block 3 moving up and down, thereby avoiding the lifting block 3 from rubbing against the inner wall of the limiting sleeve 2 when moving up and down for a long time, causing the lifting block 3 to wear, thereby improving the service life of the mold.

[0030] The feed hopper 15 is located directly above the No. 1 mold 5, and the material of the feed hopper 15 is ceramic material. By setting the feed hopper 15, when the mold casting is carried out, the casting material is poured into the feed hopper 15. At this time, the feed hopper 15 can guide the casting material to the inside of the No. 1 mold 5, and then flow to the inside of the No. 2 mold 6, thereby facilitating the addition of the casting material, that is, facilitating the casting of the ball core.

[0031] The auxiliary mechanism 16 includes an electric push rod 161, which is fixedly installed at the bottom of the support platform 1. The top of the electric push rod 161 is fixedly connected to a lifting column 162, and the lifting column 162 is movably sleeved inside the No. 2 mold 6. By setting up the auxiliary mechanism 16, when the casting of the ball core is completed, the electric push rod 161 is started, so that the electric push rod 161 can push the ball core inside the No. 2 mold 6 to move upward through the lifting column 162, so that the ball core can be moved out of the No. 2 mold 6, thereby bringing convenience to the removal of the ball core.

[0032] The working principle of the ball core casting mold of a ball valve provided by the utility model is as follows:

[0033] Step 1: First, at the end of the ball core casting, start the delivery pump 9 so that the delivery pump 9 can drive the coolant in the water tank 7 to flow to the inside of the No. 2 mold 6 through the cooling pipe 10. At this time, the coolant can absorb the heat inside the No. 2 mold 6, and then the coolant after absorbing the heat circulates to the inside of the No. 2 mold 6, thereby achieving the cooling effect of the No. 2 mold 6, avoiding the problem of slow natural cooling of the ball core, thereby greatly improving the casting efficiency of the ball core. When casting the ball core, lower the No. 1 mold 5, so that the No. 1 mold 5 can drive the positioning ring 112 to be movably sleeved in the positioning groove 111, thereby achieving the positioning of the lowered position of the No. 1 mold 5. The effect is achieved, thereby avoiding the problem of a large gap between the No. 1 mold 5 and the No. 2 mold 6 caused by the position deviation of the No. 1 mold 5, thereby improving the casting quality of the ball core. When assembling the mold, the shock absorbing plate 12 can dampen the descending No. 1 mold 5, thereby avoiding the problem of the No. 1 mold 5 colliding with the top of the No. 2 mold 6 when it descends rapidly, thereby improving the protection effect of the mold. When assembling and fixing the mold, the rotating motor 131 is started, so that the rotating motor 131 can drive the lifting block 3 to move up and down through the threaded column 132, that is, drive the No. 1 mold 5 to move up and down, so that the No. 1 mold 5 can be tightly squeezed on the top of the No. 2 mold 6, thereby achieving the combined fixing effect of the mold;

[0034] Step 2: When fixing the mold assembly, the sliding ball 14 is able to limit the position of the lifting block 3 that moves up and down, so as to avoid the lifting block 3 from rubbing against the inner wall of the limiting sleeve 2 when moving up and down for a long time, causing the lifting block 3 to wear, thereby improving the service life of the mold. When the mold is cast, the casting material is poured into the feed hopper 15. At this time, the feed hopper 15 is able to guide the casting material to the interior of the No. 1 mold 5, and then flow to the interior of the No. 2 mold 6, thereby facilitating the addition of casting materials, that is, facilitating the casting of the ball core. When the casting of the ball core is completed, the electric push rod 161 is started, so that the electric push rod 161 can push the ball core inside the No. 2 mold 6 upward through the lifting column 162, so that the ball core can be moved out of the No. 2 mold 6, thereby facilitating the removal of the ball core.

[0035] Compared with the related art, the mold for casting the ball core of a ball valve provided by the utility model has the following beneficial effects:

[0036] By setting the cooling pipe 10, when the core casting is completed, the delivery pump 9 is started, so that the delivery pump 9 can drive the coolant in the water tank 7 to flow to the inside of the No. 2 mold 6 through the cooling pipe 10. At this time, the coolant can absorb the heat inside the No. 2 mold 6, and then the coolant after absorbing the heat circulates to the inside of the No. 2 mold 6, thereby achieving the cooling effect of the No. 2 mold 6, avoiding the problem of slow natural cooling of the core, thereby greatly improving the casting efficiency of the core.
