Description

Technical Field

[0001] This utility model relates to the field of ball valve processing technology, and more specifically, it relates to an integrally molded ball valve body mold structure. Background Technology

[0002] A ball valve, as defined in the standard GB / T21465-2008 "Valve Terminology," is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve's axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves not only flexibly control the merging, splitting, and switching of flow directions in pipelines, but also allow the closure of any channel while connecting the other two.

[0003] Currently, there are molds available on the market for processing ball valve bodies. For example, CN208728639U discloses a mold for processing ball valve bodies, which includes an upper mold base, a lower mold base, a core, and a core-pulling device. By adopting the above-mentioned technical solution, pulling the ejector can simultaneously drive the clamping part out of the jammed state, simplifying the operation process and improving work efficiency. However, in actual use, the fixing operation of this mold is still relatively cumbersome, and the cooling effect of the mold is not good, resulting in the valve body requiring a long cooling time before demolding after the actual injection molding process, thus reducing processing efficiency.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an integrally molded ball valve body mold structure. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrally molded ball valve body mold structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrally molded ball valve body mold structure, including a base and a top cover installed on the base, a bottom mold and a top mold respectively provided in the base and the top cover, the bottom mold and the top mold cooperate with each other to form a mold cavity, and a cooling cavity that wraps the mold cavity is formed inside the base and the top cover when they are connected.

[0007] The base has symmetrical mounting slots on both sides. A rotating slot is also provided in the side of each mounting slot that is far apart from each other. A storage and fastening component is connected in the rotating slot. The lower end of the storage and fastening component is connected to the rotating slot through a rotating pin. The upper end of the storage and fastening component can be fastened to the top cover.

[0008] The base and top cover are connected to the bottom mold and top mold respectively. When the bottom mold and top mold are spliced ​​to form a mold cavity, the base and top cover will close at the same time to form a cooling cavity. The cooling cavity is completely wrapped around the mold cavity. Water can be injected into it to achieve rapid cooling. The base and top cover are connected by a storage and fastening component. The storage and fastening component can be stored inside the sides of the base when not in use, without obstruction. The fastening operation is simple and efficient.

[0009] Preferably, the base has a water outlet on its side between the two mounting slots, the top cover has an injection port that extends into the mold cavity, and the top cover also has a water inlet. Both the water outlet and the water inlet are connected to the cooling cavity.

[0010] The outlet and inlet can be used with external water circulation equipment to form a cooling chamber with circulating water, which has higher cooling efficiency, while the injection port facilitates the injection of molding material into the mold cavity, improving processing efficiency.

[0011] Preferably, a single storage and fastening assembly includes two pressing mechanisms and a telescopic mechanism. The two pressing mechanisms are arranged in a mirror-symmetrical manner, and their top ends are connected by the telescopic mechanism.

[0012] Each of the pressing mechanisms includes a housing and a plug hole. The plug hole is opened through the bottom of the housing, and a rotating pin is connected to a rotating groove through the plug hole. An inner cavity with a top opening is formed inside the housing. A drive motor is installed at the bottom of the inner cavity, and a screw is connected to the power output shaft of the drive motor. A threaded sleeve is threaded to the outside of the screw. One end of a hollow plate is connected to the upper end of the threaded sleeve, and the other end of the hollow plate extends to the outside of the inner cavity. A telescopic mechanism is installed between the two hollow plates.

[0013] By setting up a pressing mechanism, when the top cover needs to be fixed, the pressing mechanism is pressed down, which drives the telescopic mechanism to press down, thus achieving a quick, simple and effective fixing operation. Rotating the pin connects to the insertion interface, allowing the pressing mechanism to rotate, which facilitates subsequent storage.

[0014] Preferably, the inner cavity has symmetrical sliding grooves on both sides, and one end of a sliding block is slidably connected in the sliding groove, while the other end of the sliding block is connected to both sides of the threaded sleeve.

[0015] The sliding block, in conjunction with the sliding groove, effectively restricts the rotation of the screw sleeve, thereby achieving stable movement of the screw sleeve.

[0016] Preferably, the telescopic mechanism includes a fixed rod, a connecting rod, and a retraction spring. There are two fixed rods, each with a retraction cavity.

This allows the two pressing mechanisms to slide on the rotating pin. Only when the two pressing mechanisms move in opposite directions can they be removed from the mounting slot, ensuring no obstruction and guaranteeing the stable operation of the storage and fastening components.

[0018] Preferably, the four corners of the upper end of the base are provided with connecting posts, and the four corners of the lower end of the top cover are provided with four connecting holes, and the connecting posts are connected to the connecting holes;

[0019] The connecting posts and connecting holes work together to ensure that there is no misalignment when the base and top cover are connected, resulting in more accurate positioning and a stable connection.

[0020] Preferably, the lower end face of the top cover is further provided with a first sealing part, the inner side of the upper end face of the base is correspondingly provided with a first sealing groove, the outer edge of the upper end face of the bottom mold is provided with a second sealing groove, and the lower end face of the top mold is correspondingly provided with a second sealing part connected to the second sealing groove.

[0021] The mating connection between the first sealing part, the second sealing part, the first sealing groove, and the second sealing groove ensures that there is no leakage in the mold cavity and the cooling cavity.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. By setting a base and a top cover, the bottom mold and top mold are connected to them respectively. When the bottom mold and top mold are spliced ​​to form a mold cavity, the base and top cover will close at the same time to form a cooling cavity. The cooling cavity is completely wrapped around the mold cavity. Water can be injected inside to achieve rapid cooling. The base and top cover are connected by a storage fastening component. The storage fastening component can be stored inside the sides of the base when not in use, without obstruction. The fastening operation is simple and efficient. Attached Figure Description

[0031] like Figure 1-5 As shown, this utility model provides a base 1 and a top cover 2 installed on the base 1. A bottom mold 13 and a top mold 11 are respectively provided in the base 1 and the top cover 2. The bottom mold 13 and the top mold 11 are joined together to form a mold cavity. When the base 1 and the top cover 2 are connected, a cooling cavity is formed inside to enclose the mold cavity.

[0032] The base 1 has symmetrical mounting slots 12 on both sides. Each mounting slot 12 has a rotating slot 18 on the side that is far apart from each other. A storage fastening component 4 is connected in the rotating slot 18. The lower end of the storage fastening component 4 is connected to the rotating slot 18 through a rotating pin 5. The upper end of the storage fastening component 4 can be fastened to the top cover 2.

[0033] Each storage fastening component 4 includes two pressing mechanisms and a telescopic mechanism. The two pressing mechanisms are arranged in a mirror-symmetrical manner, and their top ends are connected by the telescopic mechanism.

[0034] Each of the pressing mechanisms includes a housing 401 and a insertion hole 402. The insertion hole 402 is opened through the bottom end of the housing 401, and the rotating pin 5 is connected to the rotating groove 18 through the insertion hole 402. The housing 401 has an inner cavity 403 with an open top. A drive motor 414 is installed at the bottom of the inner cavity 403, and the power output shaft of the drive motor 414 is connected to a screw 404. A threaded sleeve 406 is threaded to the outside of the screw 404. One end of a hollow plate 407 is connected to the upper end of the threaded sleeve 406, and the other end of the hollow plate 407 extends to the outside of the inner cavity 403. A telescopic mechanism is installed between the two hollow plates 407.

[0035] The telescopic mechanism includes a fixed rod 410, a connecting rod 413, and a retraction spring 412. There are two fixed rods 410, and each fixed rod 410 has a retraction cavity 411. The two ends of the connecting rod 413 are respectively inserted into the two retraction cavities 411. The ends of the two fixed rods 410 that are far apart from each other are connected to the outside of the hollow plate 407. The two ends of the connecting rod 413 are also provided with limiting protrusions 409, and the two ends of the retraction spring 412 are connected to the limiting protrusions 409 and the retraction cavities 411. The upper end surface of the top cover 2 is provided with a fixing groove 3, and the connecting rod 413 can be fastened into the fixing groove 3.

[0036] The inner cavity 403 has symmetrical sliding grooves 405 on both sides, and one end of the sliding block 408 is slidably connected in the sliding groove 405, and the other end of the sliding block 408 is connected to both sides of the threaded sleeve 406.

[0037] In actual use, the pressing mechanism first needs to be removed from the mounting slot 12 inside the base 1. Removing the pressing mechanism requires the cooperation of the telescopic mechanism. The two storage shells 401 need to be pulled out from the mounting slot 12. During the pulling process, the storage shells 401 will move outward outside the rotating pin 5, and at the same time drive the hollow plate 407 to move. When the two hollow plates 407 move, the two connecting rods 413 will move away from each other, and the telescopic spring will be stretched. At this time, the entire storage fastening assembly 4 is outside the base 1. Then the storage fastening assembly can be rotated. Component 4 is rotated to the top cover 2 by the rotating pin 5. At this time, the drive motor 414 can be powered by an external power source. Its operation drives the screw 404 to rotate. When the screw 404 rotates, it can drive the outer screw sleeve 406 to rotate. At the same time, the sliding blocks 408 on both sides of the screw sleeve 406 slide in the sliding groove 405 to restrict the rotation of the screw sleeve 406, so that the screw sleeve 406 drives the hollow plate 407 to move. When it moves down, the retraction mechanism can be connected to the fixing groove 3 above the top cover 2, thus realizing the function of fastening the top cover 2.

[0038] The base 1 is provided with connecting posts 16 at the four corners of the upper end, and the top cover 2 is provided with four connecting holes 9 at the four corners of the lower end. The connecting posts 16 are connected to the connecting holes 9. At this time, there will be no offset when the base 1 and the top cover 2 are connected, which will result in more accurate positioning and stable connection.

[0039] The lower end face of the top cover 2 is also provided with a first sealing part 10, the inner side of the upper end face of the base 1 is correspondingly provided with a first sealing groove 15, the outer edge of the upper end face of the bottom mold 13 is provided with a second sealing groove 14, and the lower end face of the top mold 11 is correspondingly provided with a second sealing part 17 connected to the second sealing groove 14.

[0040] Meanwhile, the first sealing part 10, the second sealing part 17, the first sealing groove 15 and the second sealing groove 14 are connected in pairs to ensure that there is no leakage in the mold cavity and the cooling cavity.

[0041] The molding material is injected into the mold cavity through injection port 8 and sealed. After injection is completed, coolant is injected through water inlet 7 to fill the cooling cavity for cooling. At the same time, it can be used in conjunction with external water circulation equipment, which is connected to water outlet 6 to realize coolant circulation. This is how the cooling is circulated.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
