Technical Field

[0001] This utility model relates to the field of mold equipment technology, specifically a mold for forming a soft-seal gate valve body. Background Technology

[0002] A soft-seal gate valve is a type of valve used to control fluid flow, employing a soft-seal material to ensure good sealing performance. It typically consists of components such as a valve body, valve cover, valve stem, valve seat, and sealing ring. The valve body is usually manufactured using a casting mold. However, existing casting molds for soft-seal gate valve bodies are not efficient at heat dissipation, potentially leading to overheating and damage during later use. Utility Model Content

[0003] The purpose of this utility model is to provide a mold for forming a soft-seal gate valve body, in order to solve the problem that the existing soft-seal gate valve body molding mold cannot efficiently dissipate heat during use, and may cause the mold to overheat and be damaged in later use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a soft-seal gate valve body forming mold, comprising: a main casting mold, an external cooling inlet pipe fixedly connected to one end of the upper part of the main casting mold, a heat dissipation fin one fixedly connected to one end of the upper part of the main casting mold, an external cooling outlet pipe fixedly connected to the other end of the upper part of the main casting mold, a heat dissipation fin two fixedly connected to the other end of the upper part of the main casting mold, an internal circulation pipe opened inside the main casting mold, a rotating guide plate rotatably connected to one end of the inner side of the internal circulation pipe, a guide plate groove opened inside the inner side of the internal circulation pipe, and rotating shaft holes opened at both ends of the inner side of the guide plate groove.

[0005] As a further embodiment of this utility model: the rotating guide plate includes an upper plate body, a guide plate rotating shaft is fixedly connected to both sides of the upper plate body, a guide plate conical plate is fixedly connected to the lower part of the upper plate body, and the guide plate rotating shaft is rotatably arranged inside the rotating shaft hole.

[0006] As a further embodiment of this utility model: the main casting mold has a casting cavity inside, and a secondary casting mold is movably adapted to the other end of the main casting mold.

[0007] As a further embodiment of this utility model, the auxiliary casting mold is also provided with an external cooling inlet pipe, a heat dissipation fin one, an external cooling outlet pipe, a heat dissipation fin two, an internal circulation pipe, a rotating guide plate, a guide plate groove, and a rotating shaft hole structure.

[0008] As a further embodiment of this utility model: the number of heat dissipation fins one is arranged in multiple sets, and the external cooling liquid inlet pipe penetrates through the interior of multiple sets of heat dissipation fins one; the number of heat dissipation fins two is arranged in multiple sets, and the external cooling liquid outlet pipe penetrates through the interior of multiple sets of heat dissipation fins two.

[0009] As a further embodiment of this utility model: multiple sets of the rotating guide plate, the guide plate groove, and the rotating shaft hole are provided, and the rotating guide plate is rotatably connected inside the guide plate groove, and every two sets of the rotating shaft hole are adapted to one set of the rotating guide plate and the guide plate groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this invention, cooling water is pumped into a rotating guide plate through an external cooling inlet pipe to efficiently dissipate heat from the mold. The rotating guide plate inside rotates via a shaft as the cooling water passes through, allowing it to rotate within a groove. This ensures that regardless of whether the cooling water enters from the external cooling inlet or outlet pipe, the rotating guide plate is impacted by the water flow and rotates to the appropriate direction to block and guide the flow, thereby improving the heat dissipation and heat exchange effect. Furthermore, the heat dissipation fins 1 and 2, which are sleeved on the outside of the external cooling inlet and outlet pipes, can further dissipate heat from the outside, resulting in even better cooling performance during use.

[0020] Reference Figures 1 to 3In this embodiment of the present invention, a mold for forming a soft-seal gate valve body includes: a main casting mold 1, an external cooling inlet pipe 2 fixedly connected to one end of the main casting mold 1, a heat dissipation fin 3 fixedly connected to one end of the main casting mold 1, an external cooling outlet pipe 4 fixedly connected to the other end of the main casting mold 1, and a heat dissipation fin 5 fixedly connected to the other end of the main casting mold 1. Multiple sets of heat dissipation fins 3 are provided, and the external cooling inlet pipe 2 penetrates through the interior of multiple sets of heat dissipation fins 3. Multiple sets of heat dissipation fins 5 are also provided. The main casting mold 1 has an internal circulation pipe 6 inside, with a rotating guide plate 7 rotatably connected to one end of the internal circulation pipe 6. The internal circulation pipe 6 has a guide plate groove 8 inside, and the guide plate groove 8 has a rotating shaft hole 9 at both ends. There are multiple sets of rotating guide plates 7, guide plate grooves 8 and rotating shaft holes 9. The rotating guide plates 7 are rotatably connected inside the guide plate grooves 8, and every two sets of rotating shaft holes 9 are adapted to one set of rotating guide plates 7 and guide plate grooves 8.

[0021] Using the above scheme: the cooling water is pumped into the rotating guide plate 6 through the external cooling inlet pipe 2 to efficiently dissipate heat from the mold. The rotating guide plate 7 inside is rotated through the guide plate shaft 11 when the cooling water passes through, and can rotate within the guide plate groove 8. In this way, no matter which side the cooling water enters from, the external cooling inlet pipe 2 or the external cooling outlet pipe 4, the rotating guide plate 7 can be rotated to the appropriate direction by the water flow to block and guide the flow, thereby improving the heat dissipation and heat exchange effect.

[0022] Reference Figure 1 , Figure 4 and Figure 5 The rotating guide plate 7 includes an upper plate body 10, with guide plate rotating shafts 11 fixed to both sides of the upper plate body 10, and a guide plate conical plate 12 fixed to the lower part of the upper plate body 10. The guide plate rotating shaft 11 is located inside the rotating shaft hole 9 and rotates. The main casting mold 1 has a casting cavity 13 inside, and a secondary casting mold 14 is movably adapted to the other end of the main casting mold 1. The secondary casting mold 14 is also equipped with an external cooling inlet pipe 2, a heat dissipation fin 1 3, an external cooling outlet pipe 4, a heat dissipation fin 2 5, an internal circulation pipe 6, a rotating guide plate 7, a guide plate groove 8, and a rotating shaft hole 9.

[0023] The working principle of this utility model is as follows: When in use, firstly, the inlet and outlet pipes are respectively installed on one end of the external cooling inlet pipe 2 and the external cooling outlet pipe 4 and connected to the cooling mechanism. At this time, the cooling water is pumped into the rotating guide plate 6 through the external cooling inlet pipe 2 to efficiently dissipate heat from the mold. The rotating guide plate 7 inside it can rotate in the guide plate groove 8 by rotating through the guide plate shaft 11 when the cooling water passes through. In this way, no matter which side of the external cooling inlet pipe 2 or the external cooling outlet pipe 4 the liquid enters, the rotating guide plate 7 can be rotated to the appropriate direction by the impact of the water flow to block and guide the flow, thereby improving the heat dissipation and heat exchange effect. In addition, the heat dissipation fins 1 3 and 2 5 sleeved on the outside of the external cooling inlet pipe 2 and the external cooling outlet pipe 4 can further dissipate heat from the outside to cool the mold, and the heat dissipation and cooling effect is better when in use.
