Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, and in particular to a die-casting mold for an automotive compressor bracket. Background Technology

[0002] As a key structural component of the automotive air conditioning system, the manufacturing quality of automotive compressor brackets directly affects the installation accuracy of the compressor, system stability, and overall vehicle performance. Currently, these parts are generally produced using aluminum alloy high-pressure casting technology to meet the requirements of lightweight, high strength, and integrated molding of complex structures. However, in the die-casting production process, mold design and the reliability of the ejection system are always the core issues affecting product quality and production efficiency.

[0003] Because automotive compressor brackets are mostly thin-walled, multi-ribbed structures, and to improve structural symmetry and stress uniformity, the two sides of the product are often designed with highly similar or even completely symmetrical ribs and features. While this symmetrical design is beneficial to the product's function, it poses a challenge to mold demolding. During the mold opening process, the clamping force between the molded part and the front and rear mold cavities tends to be balanced, resulting in an uncertain product retention position. In mold production, it is impossible to guarantee that the product will remain in the rear mold for removal. Once the product adheres to the front mold, the ejection mechanism set in the rear mold will not function. This not only requires manual intervention or the use of a robotic arm to grasp it, reducing production efficiency, but may also cause defects such as tearing, scratches, or even deformation on the product surface during forced demolding, resulting in an increased scrap rate.

[0004] Therefore, it is necessary to provide a new die-casting mold for automotive compressor brackets to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a die-casting mold for automobile compressor brackets.

[0006] This utility model provides a die-casting mold for an automotive compressor bracket, comprising: a worktable, a lower template placed on the worktable, and support frames symmetrically arranged on both sides of the worktable. The support frames are characterized by having a guide rail on opposite sides, an upper template on top of the lower template, an ejection mechanism on top of the upper template, the ejection mechanism being slidably mounted on the support frames, and a driving component on top of the ejection mechanism for driving the upper template closer to or further away from the lower template. The ejection mechanism includes an ejector plate and an upper ejector pin fixed to the ejector plate, the upper ejector pin penetrating the upper template. Slider blocks are provided on both sides of the ejector plate, the sliders being slidably connected to the support frames. When the ejector plate is at the bottom of the guide rail, there is a gap between the ejector plate and the upper template.

[0007] Preferably, the upper template has an upper mold core inside, and the lower template has a lower mold core inside, and the upper mold core and the lower mold core are combined to form a cavity.

[0008] Preferably, the driving component is a cylinder, which is located at the top of the ejector plate, and the output shaft of the cylinder is fixedly connected to the top of the upper template.

[0009] Preferably, the upper template has a feed inlet on one side and a material channel inside the upper template, with one end of the material channel connected to the feed inlet.

[0010] Preferably, the lower mold plate is provided with a lower ejector pin inside, the lower ejector pin extends into the lower mold plate and the lower mold core, and a push plate is provided on the side of the lower ejector pin that extends out of the lower mold plate to push the lower ejector pin to move.

[0011] Preferably, both the upper mold core and the lower mold core are provided with ventilation holes.

[0012] Compared with related technologies, the die-casting mold for automobile compressor bracket provided by this utility model has the following beneficial effects: By setting the distance between the ejection mechanism and the upper mold plate, a relative motion stage between the upper mold plate and the ejection mechanism is created during the mold opening process. This design can effectively force the product adhering to the upper mold plate to be demolded, so that it can be reliably retained on the lower mold plate. This fundamentally solves the problem of uncertainty in mold sticking caused by the symmetrical structure of the product and the balance of the clamping force, and ensures the stability and reliability of demolding.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a die-casting mold for an automotive compressor bracket provided by this utility model; Figure 2 for Figure 1 The diagram shows the structural schematic of the mold shell. Figure 3 for Figure 1 The sectional view shown is a structural schematic diagram; Figure 4 for Figure 1 The diagram shows the structure of the product.

[0017] In the specific implementation process, such as Figures 1-4 As shown, a die-casting mold for an automotive compressor bracket mainly consists of a worktable 1, a lower template 2, a support frame 3, an upper template 5, an ejection mechanism, and a drive assembly.

[0018] The workbench 1 serves as the basic support structure for the entire mold, providing a stable installation platform for other components. The lower mold plate 2 is placed on the workbench 1, and a lower mold core 10 is set inside the lower mold plate 2. The upper mold plate 5 is set on top of the lower mold plate 2, and an upper mold core 9 is set inside the upper mold plate 5. The upper mold core 9 and the lower mold core 10 are combined to form a cavity for molding the car compressor bracket.

[0019] Support frames 3 are symmetrically arranged on both sides of the workbench 1. A guide rail 4 is installed on the top of the opposite side of the support frame 3. The ejection mechanism is slidably arranged on the support frame 3. Specifically, the ejection mechanism includes an ejector plate 6 and an upper ejector pin 7 fixed to the bottom of the ejector plate 6. The upper ejector pin 7 passes through the upper template 5. Slider blocks 8 are provided on both sides of the ejector plate 6. The sliders 8 are slidably connected to the guide rail 4 on the support frame 3, so that the ejector plate 6 can slide smoothly up and down along the guide rail 4. In this embodiment, the upper ejector pin 7 is fixed. When the upper template 5 moves upward and touches the ejector plate 6, the ejector plate 6 will move upward with the upper template 5. When the ejector plate 6 is at the bottom of the guide rail 4, there is a certain gap between the ejector plate 6 and the upper template 5. This gap reserves space for the subsequent ejection action.

[0020] The drive assembly uses a cylinder 11, which is installed on the top of the ejector plate 6. The output shaft of the cylinder 11 is fixedly connected to the top of the upper template 5. Through the extension and retraction of the cylinder 11, the upper template 5 can be driven to move closer to or further away from the lower template 2, thereby realizing the mold closing and opening actions.

[0021] In order to inject molten material into the mold, a feed port 12 is provided on one side of the upper mold plate 5. A material channel 13 is provided inside the upper mold plate 5. One end of the material channel 13 is connected to the feed port 12, and the other end of the material channel 13 is connected to the cavity formed by the upper mold core 9 and the lower mold core 10. In this way, the molten material can enter from the feed port 12 and flow into the cavity through the material channel 13 for molding.

[0022] A lower ejector pin 14 is provided at the bottom of the lower mold plate 2. The lower ejector pin 14 extends into the interior of the lower mold plate 2 and the lower mold core 10. A push plate 15 is provided on the side of the lower ejector pin 14 that extends out of the lower mold plate 2. By pushing the push plate 15, the lower ejector pin 14 can be moved, thereby ejecting the product from the lower mold core 10 after the product is formed.

[0023] In addition, in order to expel the gas in the cavity during the die casting process and reduce the porosity defects inside the product, ventilation holes 16 are provided inside both the upper mold core 9 and the lower mold core 10.

[0024] The working principle provided by this utility model is as follows: When cylinder 11 is activated, its output shaft extends downward, pushing the upper mold plate 5 downward so that the upper mold core 9 and the lower mold core 10 gradually approach and fit tightly together, forming a closed cavity. During the mold closing process, because there is a gap between the ejector plate 6 and the upper mold plate 5, and due to the length limitation of the guide rail 4, the ejector plate 6 will not move downward with the upper mold plate 5 indefinitely. Instead, it will remain at the lowest position of the guide rail 4 when it reaches the lowest point of the guide rail 4.

[0025] Molten metal is injected into the material channel 13 inside the upper mold plate 5 through the feed port 12. The molten metal flows along the material channel 13 into the cavity formed by the combination of the upper mold core 9 and the lower mold core 10. During the feeding process, the gas in the cavity is discharged through the vent holes 16 inside the upper mold core 9 and the lower mold core 10, ensuring that the molten metal can fill the entire cavity. After the molten metal fills the cavity, a certain pressure is maintained so that the metal material fully fills all parts of the cavity under pressure and gradually solidifies and forms the product. After the pressure holding is completed, the mold and the product are allowed to cool naturally or are forced to cool using a cooling device to completely solidify the product.

[0026] After cooling is complete, cylinder 11 is activated. The output shaft of cylinder 11 retracts upward, pulling the upper mold plate 5 upward, separating the upper mold core 9 from the lower mold core 10. When the upper mold plate 5 rises to a certain position, it will touch the ejector plate 6. Since the ejector pins are fixed on the ejector plate 6, when the upper mold plate 5 touches the ejector plate 6, it will drive the ejector plate 6 to move upward along the guide rail 4. The ejector pins at the bottom of the ejector plate 6 move upward with the ejector plate 6, leaving the molded car compressor bracket on the lower mold plate 2, achieving the initial demolding of the product. After the ejector pins rise a certain distance, push plate 15 is pushed manually or through a mechanical device. Push plate 15 pushes the lower ejector pin 14 upward, removing the product from the lower mold plate 2, completing the entire demolding process.

[0027] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
