Technical Field

[0001] This utility model relates to the field of wax injection equipment technology, and in particular to a double-sided clamping fixture. Background Technology

[0002] A wax injection machine is a high-pressure injection device that injects liquid wax into a mold. Its working principle involves injecting liquid wax into the mold under specific pressure and flow rate, allowing the wax to distribute fully within the mold. The wax then cools in the mold to form the desired wax film. Wax injection machines are primarily suitable for small to medium-sized castings with less demanding processing requirements, such as automotive parts and mechanical components. Precise mold placement is a crucial step in the wax injection process; ensuring the mold is aligned with the wax nozzle and properly secured are key technical challenges that need to be addressed. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a double-sided clamping fixture that can clamp the mold and align it with the wax nozzle during the wax injection process, thereby improving the accuracy of wax injection.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A double-sided clamping fixture is provided, including a worktable for placing a mold, a top plate connected above the worktable by a support column, a mold pressing device mounted on the top plate, a mold pressing plate connected to the mold pressing device, and the mold pressing plate being movable up and down to press the mold on the worktable.

[0006] The workbench is also equipped with clamping plates on both sides, and the mold can be clamped between the two clamping plates;

[0007] The workbench is equipped with a moving mechanism underneath it to drive its movement.

[0008] Furthermore, the bottom of the clamping plate extends from the workbench and is connected to left and right clamping lifting cylinders, which can drive the clamping plate to move up and down.

[0009] Furthermore, the workbench has sliding grooves on both sides, and the clamping plates can move left and right along the sliding grooves, so that the two clamping plates can move towards the middle to clamp the mold.

[0010] Furthermore, an L-shaped support is provided below the workbench, and the two left and right lifting cylinders are connected to the L-shaped support through a transverse slide rail, and the two left and right lifting cylinders are driven to move synchronously through a synchronous gear.

[0011] Furthermore, the synchronizing gear includes synchronizing racks that are respectively connected to two left and right lifting cylinders. The two synchronizing racks are arranged vertically and a gear is arranged between them. The gear is connected to the vertical surface of the L-shaped support.

[0012] One of the synchronizing racks is connected to a centering cylinder.

[0013] Furthermore, the molding device includes a molding cylinder.

[0014] Furthermore, the molding device also includes a balancing molding cylinder.

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-2 As shown, this embodiment provides a double-sided clamping fixture, including a worktable 1 for placing a mold. A top plate 5 is connected to the top of the worktable 1 via a support column. A pressing device is installed on the top plate 5, and the pressing device is connected to a pressing plate 3. The pressing plate 3 can move up and down to press the mold on the worktable 1. In this embodiment, the pressing device includes a pressing cylinder 2 and a balancing pressing cylinder 6. The pressing cylinder 2 and the balancing pressing cylinder 6 control the balance of the pressing plate 3, balancing the pressing process and making the pressure distribution of the pressing plate 3 more uniform, preventing uneven force on the mold due to imbalance.

[0029] In this embodiment, clamping plates 4 are also provided on both sides of the workbench 1. The mold can be clamped between the two clamping plates 4. During the molding process, the clamping plates 4 on both sides can position the mold and clamp the two sides of the mold to prevent the mold from shifting, thereby improving production efficiency and product quality. Specifically, left and right clamping lifting cylinders 7 are connected to the lower part of the clamping plates 4. The left and right clamping lifting cylinders 7 can drive the clamping plates 4 to extend in and out of the workbench 1. In addition, in order to realize that the two clamping plates 4 can clamp towards the middle at the same time, thereby realizing the centering of the mold, this embodiment uses a synchronous rack and pinion structure to drive the two left and right clamping lifting cylinders 7 to move synchronously.

[0030] Specifically, the workbench 1 has sliding grooves on both sides, and the clamping plates 4 can move left and right along the sliding grooves, thereby allowing the two clamping plates 4 to move towards the center to clamp the mold. An L-shaped support 12 is provided below the workbench 1, and the two left and right lifting cylinders 7 are connected to the L-shaped support 12 via a transverse slide rail, and the two left and right lifting cylinders 7 are driven to move synchronously by a synchronous gear. Figure 3As shown, the synchronizing gear includes synchronizing racks 13 connected to two left and right clamping and lifting cylinders 7 respectively. The two synchronizing racks 13 are arranged vertically and a meshing gear 14 is provided between them. The gear 14 is connected to the vertical surface of the L-shaped support 12. One of the synchronizing racks 13 is connected to a centering cylinder 11. The left and right movement of the centering cylinder 11 pulls the connected synchronizing rack 13 to move left and right. The left and right movement of the synchronizing rack 13 drives the gear 14 to rotate. The rotation of the gear 14 drives the other synchronizing rack 13 to move left and right. Thus, the two centering cylinders 11 move simultaneously towards each other or in opposite directions, thereby simultaneously clamping or releasing the mold and achieving mold centering.

[0031] The workbench 1 is also equipped with a demolding cylinder 8, which is located on the outside of one of the clamping plates 4. After the molding is completed, the mold can be pushed out by the demolding cylinder 8, thereby realizing the automated mold pressing process.

[0032] The moving mechanism includes a first support 9 connected below the L-shaped support 12. A second support 10 is connected below the first support 9 via a transverse slide rail. The second support 10 is equipped with a mold-feeding cylinder 15 that pushes the first support 9 to move back and forth. When the mold-feeding cylinder 15 is activated, it pushes the first support 9 forward, thereby pushing the worktable 1 forward, so that the fixture is close to the mold, and cooperates with other corresponding mold-feeding devices to push the mold onto the worktable 1.

[0033] A base 16 is connected to the lower part of the second support 10 via a vertical slide rail. The base 16 is equipped with a lifting cylinder 17 that can push the second support 10 up and down. The lifting cylinder 17 can drive the second support 10 up and down, thereby driving the first support 9, the L-shaped support 12 and the worktable 1 up and down.

[0034] Workflow:

[0035] The lifting cylinder 15 and the mold-feeding cylinder 13 work together to move the worktable 1 to the position corresponding to the mold, so that the mold can be accurately pushed into the worktable 1. Then, the synchronous rack and pinion drives the two centering cylinders 11 to move to the center, while the left and right clamping lifting cylinders 7 drive the clamping plate 4 to rise, clamping the mold and centering it so that the mold can be aligned with the wax nozzle. The pressing cylinder 2 and the balancing pressing cylinder 6 drive the pressing plate 3 to descend, applying pressure to the mold. After the wax injection is completed, the left and right clamping lifting cylinders 7 drive the clamping plate 4 to descend and the clamping plate 4 moves outward, and the ejection cylinder 8 pushes the mold out.

[0036] The double-sided clamping fixture exemplified in this embodiment forms an efficient and continuous workflow from mold conveying, clamping, centering to pressing, which improves the mold pressing processing efficiency. Moreover, the mold position is accurate during the pressing process, which improves the pressing accuracy and helps to increase the yield rate of mold processing.

[0037] Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-mentioned technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-mentioned technical features or their equivalent features without departing from the inventive concept. For example, technical solutions formed by substituting the above-mentioned features with technical features disclosed in this application (but not limited to) that have similar functions.
