Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal product manufacturing equipment, specifically to die-casting equipment for aluminum alloy parts. Background Technology
[0002] Currently, most small aluminum alloy die-casting equipment on the market uses a left-right mold closing design for easy demolding. This structural design has certain rationality; during demolding, the left and right molds move to the sides respectively, providing sufficient demolding space for the formed aluminum alloy parts. At the same time, for some relatively regular-shaped aluminum alloy parts with a single demolding direction, the left-right mold closing method facilitates a smoother demolding process, effectively improving production efficiency and reducing production delays caused by demolding difficulties. For details, please refer to the invention patent application with publication number CN119813670A, entitled "A High-Pressure Casting Aluminum Rotor Production Process and Production Device," which uses a left-right mold closing structure in its device.
[0003] However, in this left-right mold structure, since the left and right molds are installed independently on the equipment, continuous pressure is required during the molding process. Under high pressure, the connection between the mold and the equipment may loosen, causing the positions of the left and right molds to shift. This displacement will change the size and shape of the mold cavity, thereby affecting the dimensional accuracy and shape consistency of the molded aluminum alloy parts. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an aluminum alloy parts die casting molding equipment.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] An aluminum alloy component die-casting equipment includes a base, a positioning bracket, a fixed mold bracket, a moving mold bracket, and a fastening bracket. The positioning bracket is mounted on the base, and the fixed mold bracket and the moving mold bracket are mounted inside the positioning bracket. The fixed mold bracket is fixed to the base, while the moving mold bracket is movably mounted on the base. A fixed mold is mounted on the fixed mold bracket, and a moving mold that cooperates with the fixed mold is mounted on the moving mold bracket. After the moving mold bracket drives the moving mold to close onto the fixed mold, the fastening bracket presses and limits the fixed mold and the moving mold in a specific position. The fastening bracket is provided with multiple limiting arms for limiting the position of the fixed mold and the moving mold. The multiple limiting arms abut against the left and right, front and back, and top positions of the fixed mold and the moving mold, respectively, to limit the position of the fixed mold and the moving mold in the left and right, front and back, and up and down directions.
[0007] Furthermore, the fastening bracket is also provided with a clamping mechanism, which is located on the side close to the moving mold. The clamping mechanism includes a first driver, a clamping arm, and a rotating seat. The rotating seat is fixed on the fastening bracket. The middle part of the clamping arm is rotatably mounted on the rotating seat to form a lever. One end of the first driver is fixed on the fastening bracket, and the other end is hinged to one end of the clamping arm. The other end of the clamping arm abuts against the moving mold. When the first driver drives one end of the clamping arm to rotate around the rotating seat, it drives the other end of the clamping arm to abut against the moving mold to generate a closing force.
[0008] In this utility model, the moving mold support includes a second driver, guide rails, sliders, a drive plate, and first support columns. The guide rails are provided in two sets and are arranged parallel to the moving direction of the moving mold on the base. The sliders are provided in two sets and are slidably sleeved on the two guide rails respectively. The drive plate is fixed on the two sliders. The first support columns are provided in multiple sets and are fixed at the bottom on the drive plate. The support contour formed by the tops of the multiple first support columns matches the contour of the bottom of the moving mold. One end of the second driver is fixed on the base, and the other end is connected to the drive plate. The second driver drives the drive plate to move along the guide rail direction, thereby causing the moving mold to separate or close with the fixed mold.
[0009] Furthermore, the fixed mold support includes multiple second support columns with the same structure as the first support column. The bottom of the second support column is fixed to the base, and the support profile formed by the tops of the multiple second support columns is adapted to the profile of the bottom of the fixed mold.
[0010] In this invention, the positioning bracket includes multiple positioning columns, a set of positioning frames, and multiple guide columns. The multiple positioning columns are fixed on the base and located around the fixed mold and the moving mold. The positioning frame is fixed on the top of the multiple positioning columns, and the multiple guide columns are arranged on the positioning frame and extend vertically. The fastening bracket includes a fastening frame that slides on the multiple guide columns and a hanger connected to the fastening frame. The limiting arm is fixed on the fastening frame. When the fastening frame slides down along the guide columns, the limiting arm abuts against the fixed mold and the moving mold. That is, the pressing contour formed by the bottom of the multiple limiting arms matches the contour of the top of the fixed mold and the moving mold.
[0011] In this invention, the ends of the limiting arm, clamping arm, first support column and / or second support column are all provided with plastic pads, that is, the plastic pads press against the mold.
[0012] This utility model has the following advantages and beneficial effects:
[0013] By setting a fastening bracket and installing multiple limiting arms on it, the fixed mold and the moving mold are limited in the left and right, front and back, and up and down directions respectively. This all-round limiting method can effectively prevent the mold position from shifting due to high pressure during the molding process, ensuring the stability of the mold cavity size and shape, and thus improving the dimensional accuracy and shape consistency of the aluminum alloy parts after molding.
[0014] Furthermore, the clamping mechanism installed on the fastening bracket uses a first driver to drive the clamping arm to rotate around the rotating seat, causing the other end of the clamping arm to abut against the moving mold and generate a closing force. This design further enhances the clamping force between the moving mold and the fixed mold, reduces quality problems caused by mold loosening, and improves the quality and stability of die casting.

A fixed mold 31 is mounted on the fixed mold bracket 3, and a fastening bracket 5 is mounted on the moving mold bracket 4 to cooperate with the fixed mold 31. The moving mold 41 is brought together on the fixed mold 31 by the moving mold support 4. The fixed mold 31 and the moving mold 41 are pressed and limited by the fastening support 5. Specifically, the fastening support 5 is provided with a plurality of limiting arms 51 for limiting the fixed mold 31 and the moving mold 41. The plurality of limiting arms 51 abut against the left, right, front, back and top parts of the fixed mold 31 and the moving mold 41 respectively, thereby limiting the fixed mold 31 and the moving mold 41 in the left and right direction, the front and back direction and the up and down direction.
[0024] Furthermore, during the pressurization process, in order to keep the fixed mold 31 and the moving mold 41 in a more stable closed state, a clamping mechanism 52 is also provided on the fastening bracket 5. The clamping mechanism 52 is located near the moving mold 41 and pushes the upper part of the moving mold 41 to continuously close, and cooperates with the moving mold bracket 4 to push the lower part of the moving mold 41 to continuously close. This ensures that the upper and lower parts of the moving mold 41 are subjected to uniform force, avoiding mold deviation. Specifically, the clamping mechanism 52 includes a first driver 521, a clamping arm 522, and a rotating seat 52. 3. The rotating seat 523 is fixed on the fastening bracket 5. The middle part of the clamping arm 522 is rotatably mounted on the rotating seat 523. One end of the first driver 521 is fixed on the fastening bracket 5, and the other end is hinged to one end of the clamping arm 522. The other end of the clamping arm 522 abuts against the moving mold 41. Preferably, the first driver 521 is a telescopic rod. When the first driver 521 drives one end of the clamping arm 522 to rotate around the rotating seat 523 to form a lever, the other end of the clamping arm 522 is driven to abut against the moving mold 41 to generate a closing force.
[0025] In this embodiment, the moving mold support 4 includes a second driver 46, guide rails 42, sliders 43, a drive plate 44, and first support columns 45. The guide rails 42 are provided in two sets and are arranged parallel to the moving direction of the moving mold 41 on the base 1. The sliders 43 are provided in two sets and are respectively slidably sleeved on the two guide rails 42. The drive plate 44 is fixed on the two sliders 43. The first support columns 45 are provided in multiple sets, and the bottom of the first support columns 45 is fixed on the drive plate 44. The support contour formed by the tops of the multiple first support columns 45 is adapted to the contour of the bottom of the moving mold 41. One end of the second driver 46 is fixed on the base 1, and the other end is connected to the drive plate 44. Preferably, the second driver 46 is a telescopic rod. The second driver 46 drives the drive plate 44 to move along the direction of the guide rails 42, thereby causing the moving mold 41 to separate or close with the fixed mold 31.
[0026] Furthermore, the fixed mold support 3 includes multiple second support columns 32 with the same structure as the first support column 45. The bottom of the second support column 32 is fixed on the base 1, and the support profile formed by the top of the multiple second support columns 32 is adapted to the profile of the bottom of the fixed mold 31.
[0027] In this embodiment, the positioning bracket 2 includes multiple positioning posts 21, a set of positioning frames 22, and multiple guide posts 23. The multiple positioning posts 21 are fixed on the base 1 and located around the fixed mold 31 and the moving mold 41. The positioning frames 22 are fixed to the top of the multiple positioning posts 21 to form a support. The multiple guide posts 23 are arranged on the positioning frames 22 and extend vertically. The fastening bracket 5 includes a fastening frame 53 that slides on the multiple guide posts 23 and a hanger 54 connected to the fastening frame 53. The limiting arm 51 is fixed on the fastening frame 53, and the fastening frame 53 slides on the guide posts 23. When the fastening frame 53 slides down along the guide posts 23, the limiting arm 51 abuts against the fixed mold 31 and the moving mold 41. That is, the pressing contour formed by the bottom of the multiple limiting arms 51 matches the contour of the top of the fixed mold 31 and the moving mold 41. In addition, the limiting effect on the mold can be improved by applying downward pressure to the hanger 54.
[0028] In this embodiment, the ends of the limiting arm 51, clamping arm 522, first support column 45 and second support column 32 are all provided with plastic pads 510, that is, the plastic pads 510 press against the mold to prevent sliding friction and improve stability.
