Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an integrated molding mold for main and auxiliary valve plates. Background Technology

[0002] The valve plate is a key functional component inside the valve used to cut off and regulate the fluid medium. It is mostly plate-shaped and achieves sealing by cooperating with the valve seat. The valve plate forming mold is a special tooling for manufacturing this component.

[0003] Currently, when the main valve plate and auxiliary valve plate in valves are cast using molds, they are usually formed separately using different molds, which results in low production efficiency and makes it inconvenient to quickly demold the valve plate after molding. Therefore, we propose an integrated molding mold for the main and auxiliary valve plates. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated molding mold for main and auxiliary valve plates, which enables the main valve plate and auxiliary valve plate to be cast and molded as a single piece, thereby improving production efficiency. At the same time, it facilitates the quick demolding of the valve plate after molding. This solves the problem that in current valves, the main valve plate and auxiliary valve plate are usually molded separately using different molds when cast and molded, which results in low production efficiency and makes it difficult to quickly demold the valve plate after molding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a main and auxiliary valve plate integrated molding mold, including a fixed frame, a first mold and a second mold. Hydraulic cylinders are symmetrically fixedly installed on both sides of the outer surface of the fixed frame. The output ends of the two hydraulic cylinders are respectively fixedly connected to the first mold and the second mold. The inner sides of the first mold and the second mold are respectively provided with a main plate mold cavity and an auxiliary plate mold cavity near the front and rear surfaces. The inner walls of the two main plate mold cavities and the two auxiliary plate mold cavities are provided with grooves. The outer sides of the first mold and the second mold are provided with through holes near the grooves. Push rods are movably inserted into the four through holes and penetrate the fixed frame. The inner ends of the four push rods are fixedly connected to a top plate. Limit blocks are fixedly installed on the outer sides of the four push rods. Limit rings are fixedly installed on the outer surfaces of the four push rods.

[0006] Preferably, both the first mold and the second mold have a pouring gate on their upper surfaces located above the main plate mold cavity and the sub-plate mold cavity, through which the pouring liquid is injected into the main plate mold cavity and the sub-plate mold cavity.

[0007] Preferably, the front and rear surfaces of the first mold and the second mold are both fixedly equipped with sliding sleeves, and the inside of the fixing frame is fixedly equipped with sliding rods near the front and rear surfaces. The sliding sleeves are slidably sleeved on the outer surface of the sliding rods. When the first mold and the second mold move in opposite directions and close, the sliding rods and sliding sleeves guide the movement of the first mold and the second mold, thereby improving the mold closing accuracy.

[0008] Preferably, both the upper and lower surfaces of the fixing frame are provided with through openings.

[0009] Preferably, the inner side of the first mold is provided with steps near the inner walls of the main plate mold cavity and the secondary plate mold cavity, and the inner side of the second mold is provided with flanges near the inner walls of the main plate mold cavity and the secondary plate mold cavity. The flanges and steps are adapted to each other. After the first mold and the second mold are closed, the flanges are inserted into the steps, which can effectively reduce the amount of molten material entering the mold gaps and thus reduce flash.

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

[0011] 1. This utility model, by setting up a fixed frame, hydraulic cylinders, a first mold, a second mold, a main plate mold cavity, a secondary plate mold cavity, a groove, an insertion hole, an ejector rod, a top plate, a limiting block, and a limiting ring, achieves the effect of integral casting of the main valve plate and the secondary valve plate, improving production efficiency, and facilitating rapid demolding of the formed valve plate. The output ends of the two hydraulic cylinders drive the first mold and the second mold to move in opposite directions respectively. After the first mold and the second mold are closed, the two main plate mold cavities are joined to form a complete main valve plate mold cavity, and the two secondary plate mold cavities are joined to form a complete secondary valve plate mold cavity. The ejector rod is restricted by the limiting block, causing the top plate to enter the groove. The casting liquid is injected into the main valve plate mold cavity and the secondary valve plate. After cooling and solidification, the main valve plate and the secondary valve plate are formed. Then, the output ends of the two hydraulic cylinders drive the first mold and the second mold frame to move in opposite directions to open the mold. The limiting ring limits the ejector rod, so the top plate moves out from the groove and ejects the main valve plate and the secondary valve plate from the main plate mold cavity and the secondary plate mold cavity, thus achieving rapid demolding.

[0012] 2. By setting up sliding rods and sliding sleeves, this utility model achieves the effect of improving mold closing accuracy. When the first mold and the second mold move in opposite directions and close, the sliding rods and sliding sleeves guide the movement of the first mold and the second mold, thereby improving the mold closing accuracy.

[0013] 3. This utility model achieves the effect of reducing flash after the valve plate is cast and molded by using steps and flanges, thereby reducing subsequent processing costs. After the first mold and the second mold are closed, the flange is inserted into the step, which can effectively reduce the amount of casting liquid entering the mold gap, thereby reducing flash.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0020] like Figures 1-4 As shown, this utility model proposes an integrated molding mold for main and auxiliary valve plates, including a fixing frame 1, a first mold 2, and a second mold 5. The fixing frame 1 is through-holes, and both the upper and lower surfaces of the fixing frame 1 are provided with through openings 6. Hydraulic cylinders 3 are symmetrically fixedly installed on both sides of the outer surface of the fixing frame 1. The output ends of the two hydraulic cylinders 3 are respectively fixedly connected to the first mold 2 and the second mold 5. The inner sides of the first mold 2 and the second mold 5 are respectively provided with a main plate mold cavity 8 and an auxiliary plate mold cavity 17 near the front and rear surfaces. The upper surfaces of the first mold 2 and the second mold 5 are located on the main plate mold plate. A pouring gate 9 is provided above the main plate mold cavity 8 and the secondary plate mold cavity 17. The inner walls of the two main plate mold cavities 8 and the two secondary plate mold cavities 17 are provided with grooves 14. The outer sides of the first mold 2 and the second mold 5 are provided with through holes 13 near the grooves 14. The four through holes 13 are movably inserted with ejector rods 10, and the ejector rods 10 pass through the fixing frame 1. The inner end of the four ejector rods 10 is fixedly connected to a top plate 16. The outer side of the four ejector rods 10 is fixedly installed with limit blocks 11. The outer surface of the four ejector rods 10 is fixedly installed with limit rings 12.

[0021] In this embodiment, the output ends of the two hydraulic cylinders 3 respectively drive the first mold 2 and the second mold 5 to move in opposite directions. After the first mold 2 and the second mold 5 are closed, the two main plate mold cavities 8 are connected to form a complete main valve plate mold cavity, and the two auxiliary plate mold cavities 17 are connected to form a complete auxiliary valve plate mold cavity. The ejector rod 10 is restricted by the limiting block 11, so that the ejector plate 16 enters the groove 14. The molten material is injected into the main valve plate mold cavity and the auxiliary valve plate through the pouring port 9. After cooling and solidification, the main valve plate and the auxiliary valve plate are formed. Then, the output ends of the two hydraulic cylinders 3 respectively drive the first mold 2 and the second mold frame 5 to move in opposite directions to open the mold. The limiting ring 12 plays a limiting role on the ejector rod 10, so the ejector plate 16 moves out from the groove 14 and ejects the main valve plate and the auxiliary valve plate inside the main plate mold cavity 8 and the auxiliary plate mold cavity 17 to achieve rapid demolding. Example 2

A sliding rod 4 is fixedly installed inside the fixing frame 1 near the front and rear surfaces, and the sliding sleeve 7 is slidably sleeved on the outer surface of the sliding rod 4.

[0023] In this embodiment, when the first mold 2 and the second mold 5 move in opposite directions and close together, the slide bar 4 and the slide sleeve 7 guide the movement of the first mold 2 and the second mold 5, thereby improving the mold closing accuracy. Example 3

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes an integrated molding mold for main and auxiliary valve plates. Compared with Embodiment 1, this embodiment further includes a step 15 provided on the inner side of the first mold 2 near the inner wall of the main plate mold cavity 8 and the auxiliary plate mold cavity 17, and a flange 18 provided on the inner side of the second mold 5 near the inner wall of the main plate mold cavity 8 and the auxiliary plate mold cavity 17, and the flange 18 and the step 15 are adapted to each other.

[0025] In this embodiment, after the first mold 2 and the second mold 5 are closed, the flange 18 is inserted into the step 15, which can effectively reduce the amount of molten material entering the mold gap, thereby reducing flash and lowering subsequent processing costs.
