Description

Technical Field

[0001] This utility model relates to the field of aluminum die casting technology, and in particular to a positioning mechanism for aluminum die casting. Background Technology

[0002] Aluminum, as a lightweight and high-performance metal, has the characteristics of low density, high strength, good corrosion resistance, and good thermal and electrical conductivity. The die casting process of aluminum parts involves injecting molten aluminum alloy into the cavity of a metal mold at extremely high speed under high pressure, and then cooling and solidifying it to form parts of the required shape and size.

[0003] During die casting, the moving mold needs to continuously close and open with the fixed mold to die cast multiple aluminum parts. Traditionally, the moving mold and the fixed mold do not close precisely when they close, which can lead to cavity misalignment, resulting in dimensional deviations or flash in the die-cast parts. This causes the die-cast aluminum parts to fail to meet the qualification requirements, thus wasting aluminum raw materials. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning mechanism for die casting aluminum parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Four sliding rods are provided between one side of the fixed mold and one end of the support frame. Triangular positioning groove 1 is opened at both ends of one side of the fixed mold. Triangular positioning groove 2 is opened at the other two ends of one side of the fixed mold. Four positioning holes are opened on one side of the fixed mold located at the four corners of the cavity. Two buffer components are provided at both ends of one side of the fixed mold.

[0007] A hydraulic cylinder is fixedly installed on one side of the support frame. The hydraulic cylinder drives the installation of a moving mold. Sliding holes are opened at the four corners of the moving mold. The moving mold is slidably sleeved on the four sliding rods through the four sliding holes. Triangular positioning blocks are set at both ends of one side of the moving mold, and triangular positioning blocks are set at both ends of the other side of the moving mold. Four positioning pins that are adapted to the positioning holes are set at the four corners of the cavity on one side of the moving mold.

[0008] In addition, a preferred structure is that two cylindrical grooves are formed at both ends of one side of the fixed mold, and the cylindrical grooves are located at the outer end of the fixed mold cavity.

[0009] In addition, a preferred structure is that the inner wall of the cylindrical groove is provided with sliding grooves on both sides, and a circular groove is provided at one end of the cylindrical groove.

[0010] Furthermore, in a preferred configuration, the buffer assembly includes a buffer post and a spring, with the spring located inside a cylindrical groove, and both ends of the spring being fixedly connected to one side of the buffer post and the bottom side of the cylindrical groove, respectively.

[0011] In addition, a preferred structure is that a contact block is provided on one side of the buffer post, and sliders are provided on both sides of one end of the buffer post, with the sliders sliding within the groove.

[0012] Furthermore, in a preferred configuration, the triangular positioning block 1 is adapted to the triangular positioning groove 1.

[0013] Furthermore, in a preferred configuration, the second triangular positioning block is adapted to the second triangular positioning groove.

[0014] The beneficial effects of this utility model are as follows:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-8 A positioning mechanism for die casting aluminum parts includes a support frame 1, a fixed mold 3 is fixedly installed on one side of the inner wall of the support frame 1, four sliding rods 5 are provided between one side of the fixed mold 3 and one end of the support frame 1, a triangular positioning groove 32 is provided at both ends of one side of the fixed mold 3, a triangular positioning groove 33 is provided at the other two ends of one side of the fixed mold 3, four positioning holes 31 are provided on one side of the fixed mold 3 located at the four corners of the cavity, and two buffer components 6 are provided at both ends of one side of the fixed mold 3.

[0027] Among them, a hydraulic cylinder 2 is fixedly installed on one side of the support frame 1. The hydraulic cylinder 2 drives the installation of the moving mold 4. Each of the four corners of the moving mold 4 has a sliding hole 41. The moving mold 4 is slidably sleeved on the four sliding rods 5 through the four sliding holes 41. Each end of one side of the moving mold 4 is provided with a triangular positioning block 43. Each end of the other side of the moving mold 4 is provided with a triangular positioning block 44. Each side of the moving mold 4 is provided with four positioning posts 42 that are adapted to the positioning holes 31 and located at the four corners of the cavity.

[0028] Meanwhile, two cylindrical grooves 34 are opened at both ends on one side of the fixed mold 3, and the cylindrical grooves 34 are located at the outer end of the cavity of the fixed mold 3.

[0029] Furthermore, the cylindrical groove 34 has sliding grooves 342 on both sides of its inner wall, and a circular groove 341 at one end of the cylindrical groove 34. When the mold is closed, the contact block 611 is squeezed into the circular groove 341.

[0030] Meanwhile, the buffer assembly 6 includes a buffer post 61 and a spring 62. The spring 62 is located in the cylindrical groove 34. The two ends of the spring 62 are fixedly connected to one side of the buffer post 61 and the bottom side of the cylindrical groove 34, respectively. The buffer assembly 6 reduces the impact force when the mold is closed and protects the moving mold 4 and the fixed mold 3.

[0031] Meanwhile, a contact block 611 is provided on one side of the buffer post 61, and sliders 612 are provided on both sides of one end of the buffer post 61. The sliders 612 slide within the groove 342, and the sliders 612 make the movement of the buffer post 61 more stable.

[0032] Furthermore, the triangular positioning block 43 is adapted to the triangular positioning groove 32, and the triangular positioning block 43 is inserted into the triangular positioning groove 32 to achieve left and right alignment between the moving mold 4 and the fixed mold 3.

[0033] At the same time, the second triangular positioning block 44 is adapted to the second triangular positioning groove 33, and the second triangular positioning block 44 is inserted into the second triangular positioning groove 33 to achieve the vertical alignment of the moving mold 4 and the fixed mold 3.

[0034] In this embodiment, the hydraulic cylinder 2 drives the moving mold 4 to move towards the fixed mold 3 via the slide rod 5. The first triangular positioning block 43 and the second triangular positioning block 44 are slowly inserted into the first triangular positioning groove 32 and the second triangular positioning groove 33, respectively. At the same time, the positioning pin 42 is inserted into the positioning hole 31. Simultaneously, the moving mold 4 contacts and presses the contact block 611, thereby causing the buffer pin 61 to compress the spring 62. The contact block 611 is then pressed into the circular groove 341, thus completing the precise positioning and mold closing of the moving mold 4 and the fixed mold 3. Then, aluminum raw materials are injected into the cavity of the moving mold 4 and the fixed mold 3 for die casting.

[0035] In this utility model, when the moving mold 4 and the fixed mold 3 are closed, the first triangular positioning block 43 and the second triangular positioning block 44 are respectively inserted into the first triangular positioning groove 32 and the second triangular positioning groove 33, and at the same time the positioning pin 42 is inserted into the positioning hole 31, thereby realizing the precise positioning and mold closing of the moving mold 4 and the fixed mold 3, which is beneficial to die-cast aluminum parts.
