Description

Technical Field

[0001] This utility model belongs to the field of constant pressure casting technology, specifically relating to a hinged metal liquid constant pressure casting device. Background Technology

[0002] A hinge is a mechanical component that connects two parts via a hinge, allowing them to rotate relative to each other. It is commonly used in mechanical parts that withstand rotation or oscillation, such as doors, windows, and robotic arms. Hinges are designed to have good wear resistance and load-bearing capacity, and are often made of materials such as steel and aluminum alloys. Depending on the application, hinges can be divided into ordinary hinges and special-purpose hinges; the latter are typically used in specialized industrial equipment.

[0003] Problems with existing technology: In the production of hinge seats, the casting method is usually adopted, in which molten metal is poured into the mold, and then waited for solidification before demolding. Constant pressure casting can make the molten metal in the mold fully contact the inner wall of the mold, thereby improving the casting quality. However, when casting with existing constant pressure molds, the mold needs to be manually moved to the constant pressure casting machine body due to the large size of the constant pressure casting machine, and then the casting is carried out, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a hinged metal liquid constant pressure casting device, which can apply external force to the casting mold by setting two structural support plates on both sides of the casting mold, and the sliding arrangement of the structural support plates can move together with the casting mold. Multiple casting molds can be moved sequentially to the bottom of the injector for casting by a drive chain.

[0005] The specific technical solution adopted by this utility model is as follows: A constant pressure casting device for hinge seat molten metal includes: a casting machine, an injector provided on one side of the casting machine, a casting mold provided below the injector, and a finished hinge seat placed inside the casting mold; A slide rail is horizontally arranged below the injector, and the top of the casting mold is slidably arranged with the slide rail; Both sides of the casting mold are provided with structural support plates, and a structural rod is fixedly connected between the two structural support plates. An access plate is provided on the side of the two structural support plates that are far apart from each other. The top of the structural support plate is slidably set with the slide rail. A hydraulic locking rod is fixedly installed on one side of the two access plates that are close to each other. The hydraulic locking rod passes through the structural support plate, and the output end of the hydraulic locking rod is detachably installed to the casting mold.

[0006] A drive chain is provided below the slide rail, and the drive chain is detachably installed from the structural support plate.

[0007] The structural support plate has a through hole near the hydraulic locking rod, and the hydraulic locking rod is inserted into the through hole. The hydraulic locking rod and the structural support plate are detachably fixed by screws.

[0008] A connecting rod is fixedly connected to the top of the structural support plate, and the connecting rod extends into the interior of the slide rail and is fixedly connected to a balance block.

[0009] Rollers are rotatably mounted on both sides of the balance block, and the rollers are in contact with the inner wall of the slide rail.

[0010] The top of the casting mold is the same as the top of the structural support plate, except that a through window is provided at the connecting rod at the top of the casting mold, and the drive chain passes through the through window.

[0011] The number of structural rods is multiple.

[0012] The top of the casting mold is provided with an injection port, which is located between the two casting molds.

[0013] A retaining ring is fixedly connected to the bottom outer side of the injection port, and a retaining groove is opened near the retaining ring of the casting mold. The retaining ring is inserted into the retaining groove for installation.

[0014] The bottom of the retaining ring is horizontally aligned with the inner wall of the top of the casting mold, and the inner edges of both ports of the injection port are arc-shaped.

[0015] The technical effects achieved by this utility model are as follows: In this invention, the two structural support plates of the casting mold are supported by structural rods. The two structural support plates are set on both sides of the casting mold to provide a stable structure to apply external force to the casting mold. The sliding arrangement of the structural support plates allows them to move together with the casting mold. Multiple casting molds can be moved sequentially to the bottom of the injector by a drive chain.

[0016] In this invention, when the output end of the hydraulic locking rod applies an external force to the casting mold, the reaction force of the casting mold will directly act on the structural support plate, keeping the overall structure stable. This allows the hydraulic locking rod to control the opening and closing of the two casting molds, thereby meeting the needs of casting and demolding. Attached Figure Description

Detailed Implementation

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, a constant pressure casting device for hinge seat molten metal includes: a casting machine 1, an injector 101 is provided on one side of the casting machine 1, a casting mold 2 is provided below the injector 101, and a finished hinge seat 6 is placed inside the casting mold 2.

[0021] In this process, the traditional casting machine 1 injects molten metal into the inside of the injector 101, and then uses a pressure device inside the injector 101 to inject the liquid metal into the inside of the casting mold 2. The liquid metal inside the casting mold 2 then solidifies, and the final product 6 of the hinge seat is produced. In this process, the casting machine 1 has a relatively large volume.

[0022] See attached document Figure 1 - Figure 2 A slide rail 3 is horizontally arranged below the injector 101, and the top of the casting mold 2 is slidably arranged with the slide rail 3; structural support plates 4 are arranged on both sides of the casting mold 2, and structural rods are fixedly connected between the two structural support plates 4. An access plate 5 is arranged on the side of the two structural support plates 4 that is far away from each other, and the top of the structural support plate 4 is slidably arranged with the slide rail 3; there are multiple structural rods.

[0023] According to the above structure, the slide rail 3 is close to the ground, which facilitates the installation and disassembly of the casting mold 2. Multiple casting molds 2 can be slidably set at the slide rail 3 for sequential pouring of molten metal. The slide rail 3 can be set as a ring, and the casting mold 2 can be used cyclically on the slide rail 3. Alternatively, the casting mold 2 can be placed on the slide rail 3 from one end and then removed from the other end. The two structural support plates 4 of the casting mold 2 are supported by structural rods, so that the distance between them is fixed and will not change due to external forces. The two structural support plates 4 are set on both sides of the casting mold 2 to provide a stable structure to apply external forces to the casting mold 2, and the sliding arrangement of the structural support plates 4 can move together with the casting mold 2.

[0024] See attached document Figure 2 - Figure 5 A hydraulic locking rod 501 is fixedly installed on one side of the two access plates 5 that are close to each other. The hydraulic locking rod 501 passes through the structural support plate 4. The output end of the hydraulic locking rod 501 is detachably installed with the casting mold 2. A through hole is opened on the structural support plate 4 near the hydraulic locking rod 501. The hydraulic locking rod 501 is inserted into the through hole. The hydraulic locking rod 501 and the structural support plate 4 are detachably fixed by screws.

[0025] According to the above structure, the hydraulic locking rod 501 is detachably installed with the structural support plate 4 and fixedly installed with the access plate 5, so that the access plate 5 can be fixed by the structural support plate 4. When the output end of the hydraulic locking rod 501 applies an external force to the casting mold 2, the reaction force of the casting mold 2 will directly act on the structural support plate 4, so that the overall structure remains stable. When liquid metal needs to be poured, hydraulic oil is injected into each hydraulic locking rod 501 through an external oil pipe, causing the output end of the hydraulic locking rod 501 to extend and push the two casting molds 2 to fit tightly together. Then, liquid metal is injected into them. After the injection is completed, the casting mold 2 and the structural support plate 4 move forward and wait for it to cool and solidify before the next casting mold 2 is used for pouring.

[0026] See attached document Figure 2 - Figure 5 A drive chain 301 is provided below the slide rail 3, and the drive chain 301 is detachably installed with the structural support plate 4; a connecting rod 401 is fixedly connected to the top of the structural support plate 4, the connecting rod 401 extends into the interior of the slide rail 3 and is fixedly connected to a balance block 402; rollers are rotatably installed on both sides of the balance block 402, and the rollers contact the inner wall of the slide rail 3; the top of the casting mold 2 is the same as the top of the structural support plate 4, except that a through window 202 is opened at the connecting rod 401 at the top of the casting mold 2, and the drive chain 301 passes through the through window 202.

[0027] According to the above structure, the drive chain 301 is externally connected to a drive toothed disc, which drives the drive chain 301 to transmit power as needed. During this process, the drive chain 301 is connected to the top of the structural support plate 4 by bolts or pins, so that the drive chain 301 can push the structural support plate 4 to move synchronously during transmission. The roller is used to reduce friction with the slide rail 3. During the movement, the drive chain 301 pushes the structural support plate 4 to move. Since the casting mold 2 has a through window 202 near the drive chain 301, the casting mold 2 is not connected to the drive chain 301. During the movement of the structural support plate 4, the access plate 5 and the hydraulic locking rod 501 slide at the slide rail 3. The casting mold 2 is completely pushed by the hydraulic locking rod 501. This means that when the hydraulic locking rod 501 pushes the casting mold 2 to pour or moves away from each other, the casting mold 2 will not be affected by the drive chain 301. When it is necessary to remove the finished hinge seat 6 after it has been cast and cooled, the workers need to set up a lifting platform below the casting mold 2, and then connect the oil pipe to extract the hydraulic oil inside the hydraulic locking rod 501, so that the sliding rod inside the hydraulic locking rod 501 retracts and separates the two casting molds 2, thereby removing the finished hinge seat 6. The slide rail 3 limits the upper and lower ends of the roller, so that the balance block 402 can prevent the casting mold 2 or the structural support plate 4 from tilting due to the unbalanced force on both sides.

[0028] See attached document Figure 5 The top of the casting mold 2 is provided with an injection port 201, which is located in the middle of the two casting molds 2. A retaining ring 204 is fixedly connected to the bottom outer side of the injection port 201. A retaining groove 203 is opened near the retaining ring 204 in the casting mold 2. The retaining ring 204 is inserted into the retaining groove 203. The bottom of the retaining ring 204 is set horizontally with the inner wall of the top of the casting mold 2. The inner edges of the two ports of the injection port 201 are both set as arcs.

[0029] According to the above structure, during casting, excess liquid metal will rise above the casting mold 2 and accumulate inside the injection port 201. To facilitate demolding, the injection port 201 is independently set. When the hinge base finished product 6 is separated from the casting molds 2 on both sides, the accumulated metal will restrict the injection port 201. At this time, the injection port 201 needs to be lifted upward to separate it from the hinge base finished product 6. During casting, the retaining ring 204 and the retaining groove 203 can be inserted to temporarily limit the injection port 201. When the two casting molds 2 are close to each other, the injection port 201 will be completely limited. The arc-shaped port design can prevent the contact surface with the liquid metal from being too large, which would lead to demolding difficulties.

[0030] The working principle of this utility model is as follows: The two structural support plates 4 set on the casting mold 2 are supported by the structural rod. The two structural support plates 4 are set on both sides of the casting mold 2 to provide a stable structure to apply external force to the casting mold 2. The sliding arrangement of the structural support plates 4 can move together with the casting mold 2. The multiple casting molds 2 can be moved sequentially to the bottom of the injector 101 through the drive chain 301. When the output end of the hydraulic locking rod 501 applies external force to the casting mold 2, the reaction force of the casting mold 2 will directly act on the structural support plate 4, so that the overall structure remains stable. The hydraulic locking rod 501 can control the opening and closing of the two casting molds 2, thereby meeting the needs of casting and demolding.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
