Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically to a connecting plate casting mold. Background Technology

[0002] In the foundry industry, plate casting molds are key equipment for producing various metal parts. Traditional casting molds have certain limitations in design and function, especially in mold opening, cooling, and finished product ejection. Traditional molds typically rely on natural cooling or simple air cooling, resulting in low cooling efficiency, difficulty in mold separation, and inconsistent finished product quality. Furthermore, traditional molds often require complex mechanical structures or manual operation to eject finished products, which not only increases production costs but also reduces production efficiency. To address these problems, this invention proposes a plate casting mold. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a connecting plate casting mold that can automatically cool down during mold opening.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a connecting plate casting mold, comprising:

[0005] A frame, wherein the interior of the frame is provided with an inner cavity;

[0006] A fixed mold is fixed on a frame. The mold has an inlet inside and an injection device communicating with the inlet on one side.

[0007] A moving mold is slidably installed in an inner cavity. A cavity is provided between the fixed mold and the moving mold. An ejector rod is provided inside the moving mold and abuts against the inside of the cavity.

[0008] The frame is equipped with an air inlet pipe. One end of the air inlet pipe is connected to the inner cavity, and the other end is connected to the junction of the fixed mold and the moving mold. When the moving mold and the fixed mold open, the air inlet pipe can blow the gas in the inner cavity to the gap between the fixed mold and the opening of the fixed mold.

[0009] Preferably, a piston plate is slidably installed in the inner cavity. During the mold opening process, the piston plate can slide towards the moving mold and pressurize the gas in the inner cavity and inject it into the air inlet pipe.

[0010] Preferably, multiple linkage mechanisms are provided between the moving mold and the piston plate. Each linkage mechanism includes a side plate fixed on the moving mold and the piston plate. The linkage mechanism also includes a gear rotatably installed inside the frame. The gear meshes with the two corresponding side plates. When the gear rotates, the moving mold and the piston plate can slide inward or outward synchronously.

[0011] Preferably, an air intake pipe is fixed on the frame, one end of which is connected to the inner cavity and the other end is connected to a cooling device.

[0012] Preferably, the push rod is slidably mounted on the push rod by a spring, and the end of the push rod away from the cavity extends into the inner cavity and is movably connected to the piston plate.

[0013] Preferably, the moving mold has cooling holes inside, and the cooling holes are connected to the inner cavity.

[0014] Preferably, the injection device includes a feed pipe fixed to the fixed mold, a feed cylinder fixed above the feed pipe, and a push plate slidably installed inside the feed pipe, the push plate being able to push the material inside the feed cylinder into the cavity.

[0015] Preferably, a hydraulic cylinder is fixed on the fixed mold, and the output end of the hydraulic cylinder passes through the fixed mold and is connected to the moving mold.

[0016] The beneficial effects of this utility model are as follows:

[0017] By installing a piston plate within the inner cavity and pressurizing the gas in the cavity during mold opening and injecting it into the air inlet pipe, followed by cooling, rapid cooling of the mold is achieved. This design not only improves cooling efficiency but also facilitates rapid mold separation, reducing the production cycle.

[0018] The moving mold and the piston plate are connected by multiple linkage mechanisms, enabling synchronous inward or outward sliding. The ejector pin is slidably mounted on the ejector rod via a spring and is movably connected to the piston plate. During mold opening, the movement of the piston plate drives the ejector pin to move together, thereby automatically ejecting the finished product from the cavity. Attached Figure Description

[0024] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0025] Example 1

[0026] like Figures 1-4 As shown in the figure, in this embodiment, a plate casting mold is provided, including a frame 1, a fixed mold 2 and a moving mold 3.

[0027] The frame 1 has an internal cavity 8. The fixed mold 2 is fixed to the frame 1. The fixed mold 2 has a feed port inside. One side of the fixed mold 2 is equipped with an injection device that communicates with the feed port. The fixed mold 2 is used to introduce casting material. The fixed mold 2 is also equipped with an injection device connected to the feed port on one side, which is used to inject material into the mold.

[0028] The moving mold 3 is slidably installed in the inner cavity 8. A cavity 4 is provided between the fixed mold 2 and the moving mold 3. An ejector rod 12 is provided inside the moving mold 3. The ejector rod 12 abuts against the inside of the cavity 4. The cavity 4 is where the product shape is cast. The ejector rod 12 contacts and supports the inside of the cavity 4 and is used to push out the finished product when the mold is opened.

[0029] The frame 1 is equipped with an air inlet pipe 9. One end of the air inlet pipe 9 is connected to the inner cavity 8, and the other end is connected to the junction of the fixed mold 2 and the moving mold 3. When the moving mold 3 and the fixed mold 2 open, the air inlet pipe 9 can blow the gas in the inner cavity 8 to the gap between the fixed mold 2 and the fixed mold 2. When the moving mold 3 and the fixed mold 2 separate (i.e., open), the air inlet pipe 9 can blow the gas in the inner cavity 8 to the gap between the two mold parts. The rapid cooling of the mold helps to quickly separate the mold.

[0030] The ejector pin 12 is slidably mounted on the ejector pin 12 by a spring. The end of the ejector pin 12 away from the cavity 4 extends into the inner cavity 8 and is movably connected to the piston plate 11. This design allows the piston plate 11 to move together with the ejector pin 12 when the mold is opened, thereby ejecting the finished product from the cavity 4. When the mold is opened, the moving mold 3 and the piston plate 11 move together. When the piston plate 11 moves to the end, it will contact the ejector pin 12 and eject the product from the cavity 4 through the ejector pin 12.

[0031] The injection device includes a feed pipe 5 fixed to the fixed mold 2, a feed cylinder 7 fixed above the feed pipe 5, and a push plate 6 slidably installed inside the feed pipe 5. The push plate 6 can push the material inside the feed cylinder 7 into the cavity 4 for feeding the material inside the cavity 4. The raw material of this casting mold is heated molten iron.

[0032] A hydraulic cylinder is fixed on the fixed mold 2. The output end of the hydraulic cylinder passes through the fixed mold 2 and is connected to the moving mold 3. The output end of the hydraulic cylinder can push the moving mold 3 to move.

[0033] Example 2

[0034] like Figures 1-4 As shown, based on Example 1, this example provides a mold-opening process, as detailed below:

[0035] A piston plate 11 is slidably installed in the inner cavity 8. During the mold opening process, the piston plate 11 can slide towards the moving mold 3 and pressurize the gas in the inner cavity 8 and inject it into the air inlet pipe 9. When the mold opening operation is performed, the piston plate 11 will slide towards the moving mold 3. During the sliding process, the piston plate 11 will pressurize the gas in the inner cavity 8 and inject the gas into the air inlet pipe 9.

[0036] Multiple linkage mechanisms are provided between the moving mold 3 and the piston plate 11. Each linkage mechanism includes a side plate 10 fixed on the moving mold 3 and the piston plate 11. The linkage mechanism also includes a gear 15 rotatably installed inside the frame 1. The gear 15 meshes with the two corresponding side plates 10. When the gear 15 rotates, the moving mold 3 and the piston plate 11 can slide inward or outward synchronously. When the gear 15 rotates, due to the meshing relationship, the moving mold 3 and the piston plate 11 can slide inward or outward synchronously to achieve coordinated movement.

[0037] Example 3

[0038] like Figures 1-4 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a gas flow method, as detailed below:

[0039] An air inlet pipe 9 is fixed to the frame 1. One end of the air inlet pipe 9 is connected to the inner cavity 8, and the other end is connected to a cooling device 14. The air inlet pipe 9 is connected to the inner cavity 8 to introduce or exhaust gas from the inner cavity 8. The other end of the air inlet pipe 9 is connected to a cooling device 14, which may be used to cool or process the gas.

[0040] The moving mold 3 is equipped with a cooling hole 13 inside, which is connected to the inner cavity 8. This can effectively regulate the temperature of the moving mold 3 and prevent overheating or affecting the casting quality.

[0041] Working principle:

[0042] Casting material (such as heated molten iron) is injected into the cavity 4 between the fixed mold 2 and the moving mold 3 through an injection device. The injection device includes a feed pipe 5 fixed to the fixed mold 2 and a feed cylinder 7 above it. A pusher plate 6 is slidably installed inside the feed pipe 5 to push the material into the cavity 4. After the casting material is injected into the cavity 4, the mold is cooled by natural cooling or an auxiliary cooling device 14, so that the casting material gradually solidifies into a finished product of the desired shape.

[0043] Once the casting material has completely solidified, the output end of the hydraulic cylinder pushes the moving mold 3 to move, while the linkage mechanism causes the moving mold 3 and the piston plate 11 to slide synchronously. During the sliding process, the piston plate 11 pressurizes the gas in the inner cavity 8 and injects it into the air inlet pipe 9, where it is then processed by the cooling device 14. During the mold opening process, the movement of the piston plate 11 drives the ejector rod 12 to move together, thereby automatically ejecting the finished product from the cavity 4. This design simplifies the finished product ejection process and improves production efficiency and quality.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
