[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves are typically manufactured using casting processes.

[0003] Chinese patent CN222403418U discloses a valve casting molding die, belonging to the field of valve manufacturing. It includes a support column, a support plate fixedly connected to the top of the support column, a lower die on the top of the support plate, a mold closing mechanism above the lower die, and a demolding mechanism at the bottom of the lower die. The lower die consists of a base plate and multiple side plates. The base plate is fixedly connected to the top of the support plate, and the side plates are slidably connected to the top of the base plate. An adjustment mechanism is provided around the lower die. The beneficial effect is that the adjustment mechanism includes a connecting rod and an extension rod. The ends of the connecting rod and the extension rod that are close to each other are wedge-shaped. An electric push rod drives a horizontal plate to move the push rod upwards, ejecting the valve casting. Simultaneously, the connecting rod, driven by the extension rod, moves the side plates away from each other, increasing the gap between the side plates and the valve casting, reducing friction between them, and preventing any impact on the quality of the valve casting.

[0004] The aforementioned patent has some shortcomings: In the existing technology for valve casting, the high temperature of the workpiece after casting means that the workpiece needs to be cooled down for a long time after casting is completed, which leads to the problem of low casting efficiency.

[0019] Please see Figure 1-3 This utility model provides an embodiment of a bypass valve molding die that facilitates demolding, comprising a support platform 1, a cooling water tank 2 fixedly sleeved at the bottom of the support platform 1, a support rod 3 fixedly connected to the top of the support platform 1, a top plate 4 fixedly connected to the top of the support rod 3, a cylinder 5 fixedly mounted on the top of the top plate 4, a limit sleeve 6 fixedly connected to the bottom of the cylinder 5, a first slider 7 movably sleeved inside the limit sleeve 6, a second slider 8 movably sleeved inside the limit sleeve 6, a rotary motor 9 fixedly mounted on the side of the limit sleeve 6, a bidirectional threaded rod 10 fixedly connected to the output shaft of the rotary motor 9, a first mold 11 fixedly connected to the bottom of the first slider 7, a second mold 12 fixedly connected to the bottom of the second slider 8, a demolding mechanism 13 provided on the side of the second mold 12, and a moving mechanism 14 provided at the bottom of the support platform 1.

[0020] Mold 11 and Mold 12 are symmetrically distributed around cylinder 5, with Mold 11 located directly above cooling water tank 2. By setting up cooling water tank 2, when the casting of the workpiece is finished, cooling water is injected into the cooling water tank 2 and cylinder 5 is activated. This allows cylinder 5 to move Mold 11 and Mold 12 up and down through limit sleeve 6, and then enter the interior of cooling water tank 2. This allows the cooling water to quickly cool Mold 11 and Mold 12, thus rapidly cooling the casting and greatly reducing the workpiece cooling time, which in turn greatly improves the casting quality of the workpiece.

[0021] The bidirectional threaded rod 10 is threaded inside the first slider 7, and the bidirectional threaded rod 10 is movably sleeved inside the limiting sleeve 6. By setting the bidirectional threaded rod 10, when valve casting is required, the rotary motor 9 is started, so that the rotary motor 9 can drive the first slider 7 and the second slider 8 to move in opposite directions through the bidirectional threaded rod 10, that is, drive the first mold 11 and the second mold 12 to be combined and fixed, thereby achieving the combined and fixed effect of the casting mold.

[0022] The demolding mechanism 13 includes a positioning seat 131, which is fixedly connected to the front of the first mold 11. A pusher frame 132 is movably sleeved on the side of the second mold 12, and a tension spring 133 is movably sleeved on the outside of the pusher frame 132. By setting the demolding mechanism 13, when the first mold 11 and the second mold 12 are combined and fixed, the positioning seat 131 can push the pusher frame 132 to move horizontally, that is, drive the tension spring 133 to stretch. When the first mold 11 and the second mold 12 are separated, the tension spring 133 can drive the pusher frame 132 to move horizontally in the opposite direction, so that the pusher frame 132 can push the casting inside the second mold 12 to move out from the inside, thereby achieving the effect of automatic demolding of the workpiece, thus bringing convenience to the casting of valves.

[0023] The moving mechanism 14 includes a support column 141, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 142 is installed at the bottom of the support column 141. By setting up the moving mechanism 14, when the mold needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 142 can drive the support platform 1 to move horizontally through the support column 141, that is, drive the No. 1 mold 11 to move horizontally, thereby achieving the effect of moving and transporting the casting mold and bringing convenience to the adjustment of the working position of the casting mold.

[0024] Working principle: When the casting of the workpiece is finished, cooling water is injected into the cooling water tank 2 and cylinder 5 is activated. Cylinder 5, through the limiting sleeve 6, moves molds 11 and 12 up and down, entering the cooling water tank 2. This allows the cooling water to quickly cool molds 11 and 12, thus rapidly cooling the casting and significantly reducing the cooling time, thereby greatly improving the casting quality. When valve casting is required, the rotary motor 9 is activated. The rotary motor 9, through the bidirectional threaded rod 10, moves sliders 7 and 8 in opposite directions, thus combining and fixing molds 11 and 12. This achieves the combined fixing effect of the casting molds. The process of casting molds 11 and 12 is then completed. When the assembly is fixed, the positioning seat 131 can push the pusher frame 132 to move horizontally, which in turn drives the tension spring 133 to stretch. When the first mold 11 and the second mold 12 are separated, the tension spring 133 can drive the pusher frame 132 to move horizontally in the opposite direction, thereby allowing the pusher frame 132 to push the casting inside the second mold 12 out from the inside, thus achieving the effect of automatic demolding of the workpiece, which brings convenience to the casting of valves. When the mold needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 142 can drive the support platform 1 to move horizontally through the support column 141, which in turn drives the first mold 11 to move horizontally, thus achieving the effect of moving and transporting the casting mold, which brings convenience to the adjustment of the working position of the casting mold. The contents not described in detail in this description are the prior art known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
