Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to a shaping tooling fixture for aluminum alloy die castings. Background Technology

[0002] Die-casting shaping fixtures are process equipment used in the die-casting production process, typically consisting of positioning devices, clamping mechanisms, and support structures. They precisely position and reliably clamp the die-cast parts, ensuring they maintain their intended shape and dimensional accuracy during cooling and subsequent processing. This prevents defects such as deformation and displacement, thereby guaranteeing the quality and consistency of the die-cast parts and improving production efficiency and product qualification rate.

[0003] In the prior art, CN113953992A discloses a heat-setting upper clamping fixture, including a base, an elastic plate, and a pressure plate; the base, elastic plate, and pressure plate are all horizontally arranged, with the elastic plate positioned between the base and the pressure plate; support rods are provided on both the left and right sides of the base near the elastic plate, with the end of the support rod away from the base passing through the elastic plate and the pressure plate in sequence; a first horizontal groove is provided in the middle of the elastic plate, and elastic extrusion mechanisms are installed on the left and right sides of the first horizontal groove, with the top of the elastic extrusion mechanism fixedly connected to the lower surface of the pressure plate.

[0004] However, in the existing technology, the fixtures for aluminum alloy die casting have problems such as slow and inaccurate positioning and assembly of the upper and lower molds, and the molds are prone to displacement or loosening during the die casting process, which makes it difficult to guarantee product quality and dimensional accuracy. At the same time, the fixtures have poor versatility, making it difficult to adapt to the positioning holes of lower molds of different sizes. In addition, the fixtures suffer great wear and tear from the impact of external forces during die casting, resulting in a short service life and high production costs. They cannot operate stably and reliably in various die casting production processes. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a shaping tooling fixture for aluminum alloy die castings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shaping fixture for aluminum alloy die castings, comprising a base, with clearance grooves at both ends of the base, a rotating shaft slidably connected to the inner wall of the clearance groove, a limit post fixedly connected to the top of the rotating shaft, a sleeve rotatably connected to the outer wall of the limit post, a clamping arm fixedly connected to the top of the sleeve, a limit step provided on the inner wall of the sleeve, a compression spring installed at the bottom of the limit step, a threaded post fixedly connected to the top of the limit post, and a knob nut threadedly connected to the outer wall of the threaded post.

[0007] Preferably, a support column one is rotatably connected at the center of the base, and a support column two is provided above the top of the support column one.

[0008] Preferably, a compression spring is fixedly connected between support column one and support column two, and a support plate is fixedly connected to the top of support column two.

[0009] Preferably, a washer is fixedly connected to the bottom end of the knob nut.

[0010] Preferably, the outer walls of both compression spring one and compression spring two are coated with rust inhibitor.

[0011] Preferably, a foam board is fixedly connected to the bottom end of the clamping arm, and a lubricant is applied to the outer wall of the threaded column.

[0012] Preferably, the inner diameter of the sleeve is larger than the outer diameter of the limiting post, and the top of the clamping arm is provided with anti-slip texture.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the positioning of the upper and lower molds is achieved quickly and accurately through the axial positioning of the limiting post and the positioning hole of the lower mold, combined with the design of the sleeve and the clamping arm. After the upper mold is placed, the clamping arm is rotated to make it snap inward onto the surface of the upper mold. Then, the position of the clamping arm is firmly locked by the cooperation of the knob nut and the threaded post, preventing the mold from shifting or loosening during the die casting process. This provides stable and reliable conditions for the forming of aluminum alloy die castings, effectively ensuring product quality and dimensional accuracy.

[0015] 2. In this utility model, the clearance grooves at both ends of the base cooperate with the rotating shaft, allowing for flexible adjustment of the distance between the two limiting posts. This adapts to the positioning holes of lower molds of different sizes, significantly improving the versatility of the tooling fixture. Simultaneously, the buffer structure at the center of the base, consisting of support post one, support post two, and compression spring one, effectively absorbs the pressure from above the mold during die casting, reducing wear and tear on the tooling caused by external impacts, extending its service life, lowering production costs, and ensuring stable and reliable operation of the tooling fixture in various die casting production processes.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1-4 As shown, this utility model provides a shaping fixture for aluminum alloy die castings, including a base 1. Both ends of the base 1 are provided with clearance grooves 13. A rotating shaft 6 is slidably connected to the inner side wall of the clearance groove 13. A limiting post 7 is fixedly connected to the top end of the rotating shaft 6. A sleeve 8 is rotatably connected to the outer side wall of the limiting post 7. A clamping arm 10 is fixedly connected to the top end of the sleeve 8. A limiting step 14 is provided on the inner side wall of the sleeve 8. A compression spring 9 is installed at the bottom end of the limiting step 14. A threaded post 12 is fixedly connected to the top end of the limiting post 7. A knob nut 11 is threadedly connected to the outer side wall of the threaded post 12.

[0024] The specific settings and functions of this embodiment are described below. During die casting, the lower mold of the die casting module is installed on the support plate 5. The positioning hole of the lower mold is axially positioned with the limiting post 7. Then, the sleeve 8 and the clamping arm 10 are inserted into the outer wall of the limiting post 7. The sleeve 8 is installed in the positioning hole of the lower mold. The upper mold is stacked on the surface of the lower mold. The size of the upper mold is smaller than that of the lower mold. It is placed between the two limiting posts 7. In the initial state, the clamping arms 10 on the two limiting posts 7 are placed outward. After placement, rotate the clamping arm 10 by a certain angle so that the clamping arms 10 on the two limiting posts 7 are set inward. At this time, the two clamping arms 10 are respectively fastened to the upper surface of the upper mold, realizing the positioning function of the lower mold and the upper mold. Finally, rotate the knob nut 11 on the outer wall of the threaded post 12. After pressing the knob nut 11 downward, the knob nut 11 fits against the upper surface of the clamping arm 10. The tight fit of the knob nut 11 locks the position of the clamping arm 10, thereby fixing the orientation of the clamping arm 10.

[0025] Example 2: Figure 2 and Figure 4 As shown, a support column 1 (2) is rotatably connected to the center of the base 1, and a support column 2 (4) is positioned above the top of the support column 1 (2). A compression spring 3 (3) is fixedly connected between the support column 1 (2) and the support column 2 (4), and a support plate 5 is fixedly connected to the top of the support column 2 (4). A washer is fixedly connected to the bottom of the knob nut 11. The outer walls of both the compression spring 1 (3) and the compression spring 2 (4) are coated with rust inhibitor. A foam board is fixedly connected to the bottom of the clamping arm 10, and a lubricant is applied to the outer wall of the threaded post 12. The inner diameter of the sleeve 8 is larger than the outer diameter of the limiting post 7, and the top of the clamping arm 10 is provided with anti-slip texture.

[0026] The overall effect of this embodiment is that different die-casting molds have different sizes. In order to adapt to different positioning effects, clearance grooves 13 are opened at both ends of the base 1. The rotating shaft 6 is installed on the inner side wall of the clearance groove 13. The clearance groove 13 provides a position adjustment range for the rotating shaft 6, thereby controlling the distance between the two limit posts 7 so that the tooling can be used with the positioning holes of different lower molds. A support post 1 2 is set at the center of the base 1. The outer diameter of the support post 2 4 is larger than the outer diameter of the support post 1 2, and the top end of the support post 1 2 is sleeved on the bottom end of the support post 2 4. A compression spring 1 3 is set between the support post 1 2 and the support post 2 4 to provide force buffering, thereby reducing the pressure from above the die-casting mold and providing protection for the entire tooling so that it can be used in the die-casting production process.

[0027] The usage and working principle of this device are as follows: During operation, first, install the lower die of the die-casting module on the support plate 5, positioning it along the axis of the limiting post 7 via the lower die positioning hole. Then, place the sleeve 8 and clamping arm 10 onto the limiting post 7, positioning the sleeve 8 in the lower die positioning hole. Next, place the upper die, smaller than the lower die and located between the two limiting posts 7. Rotate the clamping arm 10 to make it snap inwards onto the upper surface of the upper die, thus positioning the upper and lower dies. Finally, rotate the knob nut 11 to lock the position of the clamping arm 10. Furthermore, the clearance grooves 13 at both ends of the base 1, in conjunction with the rotating shaft 6, can adjust the distance between the two limiting posts 7 to accommodate different lower die positioning holes. At the center of the base 1, the support post 2 with a compression spring 3 and the support post 4 work together to buffer the pressure from above the die-casting mold, protecting the tooling and making it suitable for the die-casting production process.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
