Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to die-cast base for automotive brackets. Background Technology

[0002] With the improvement of people's living standards and their enthusiasm for various outdoor sports and long-distance travel, cars, as a common means of transportation, often need to carry a lot of equipment. Car roof racks have emerged to meet this need. Installed on the roof of a car, they provide owners with extra cargo space for various items such as skis, surfboards, bicycles, tents, and large suitcases that cannot fit in the trunk. This greatly satisfies people's needs for conveniently carrying various equipment, making travel more convenient. In the production process of car roof racks, die casting plays a crucial role. Die casting has the advantage of accurately replicating the mold shape, resulting in car roof racks with small dimensional tolerances and effectively increasing their structural strength. Therefore, die casting has become one of the common manufacturing methods for car roof racks. However, existing die-cast bases for car roof racks often retain mold release agent inside the base after die casting. While the mold release agent helps the workpiece to be easily demolded during the die casting process, if the residual mold release agent inside the die-cast base is not cleaned after die casting, it will affect the subsequent performance of the die-cast base. Furthermore, the residual mold release agent may corrode the internal structure of the die-cast base, shortening its service life. Therefore, this utility model proposes a die-cast base for automotive brackets. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background art that after die casting of automotive bracket die casting bases, mold release agent remains inside the base. Although the mold release agent helps the workpiece to be demolded smoothly during the die casting process, if the mold release agent remaining inside the die casting base after die casting is not cleaned, it will affect the subsequent performance of the die casting base. Furthermore, the residual mold release agent may also corrode the internal structure of the die casting base and shorten its service life. Therefore, this invention proposes a die casting base for automotive brackets.

[0004] The technical solution of this utility model: a die-casting base for an automotive bracket, comprising: a base for support, a guide block fixedly disposed on the upper surface of the base, and two sets of sealing posts fixedly disposed on the upper surface of the guide block; guide rods fixedly disposed at the four corners of the upper surface of the base, a lower mold assembly for die-casting an automotive bracket movably sleeved on the outer wall of the guide rods, a spring sleeved on the outer wall of the guide rods, one end of the spring being fixedly connected to the base, and the other end of the spring being fixedly connected to the lower mold assembly; and a cleaning assembly disposed on one side of the lower mold assembly for cleaning internal residual impurities.

[0005] Optionally, the lower mold assembly includes a guide plate, on the bottom surface of which a lower mold is fixedly mounted, and on the upper surface of the lower mold are two sets of through holes corresponding to the sealing posts.

[0006] Optionally, the cleaning assembly includes a fixed frame fixedly disposed on one side of the guide plate, a cylinder fixedly installed on one side of the fixed frame, the output end of the cylinder passing through the guide plate and extending and fixedly connected to a scraper, the scraper being slidably disposed inside the lower mold.

[0007] Optionally, a water guide strip is fixedly provided on the upper surface of the base, the water guide strip is located on one side of the guide block, and a water guide groove is formed on the upper surface of the water guide strip.

[0008] Optionally, a limit block is fixedly provided at the upper end of the guide rod.

[0009] Optionally, the upper surface of the guide block and the bottom surface of the lower mold are inclined.

[0010] Optionally, the upper surface of the guide block is provided with a guide groove, and the bottom surface of the lower mold is fixedly provided with a sealing pressure block corresponding to the guide groove.

[0011] Optionally, a set of mounting blocks are fixedly provided on each side of the base.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model uses a guide plate, a lower mold, and a through hole in conjunction with a guide block and a sealing column. The upper mold presses the lower mold downward, so that the through hole on the lower mold and the sealing column interlock. This facilitates the flow of internal cleaning water when cleaning the inside of the lower mold, thereby improving cleaning efficiency.

[0014] Furthermore, the cleaning component plays a crucial role in the die-casting base of automotive brackets. Its fixing frame is installed on one side of the guide plate, and the scraper connected to the output end can accurately penetrate into the lower mold. After each die casting is completed, the cylinder is activated, pushing the scraper to quickly and powerfully scrape away the release agent and various impurities remaining in the mold. This prevents the release agent from adhering for a long time and causing corrosion to the base, effectively extending the overall service life of the die-casting base and keeping it in good working condition to ensure the smooth progress of subsequent die casting tasks.

A spring 6 is sleeved on the outer wall of the guide rods 4, one end of the spring 6 is fixedly connected to the base 1, and the other end of the spring 6 is fixedly connected to the lower die assembly 5, which can make the lower die assembly 5 stably move vertically up and down; a cleaning assembly 7 for cleaning residual impurities inside is arranged on one side of the lower die assembly 5, which is convenient for cleaning the lower die assembly 5.

[0031] As Figure 1 and Figure 2 As shown, the lower die assembly 5 includes a guide plate 51, and the guide plate 51 is movably sleeved on the guide rods 4, which can stably guide the guide plate 51. A lower die 52 is fixedly arranged on the bottom surface of the guide plate 51, and two through holes 53 corresponding to the sealing columns 3 are opened on the upper surface of the lower die 52, which can block the lower die 52 to form a sealed space.

[0032] As Figure 1 and Figure 2 As shown, the cleaning assembly 7 includes a fixed frame 71 fixedly arranged on one side of the guide plate 51, and the fixed frame 71 is arranged in a "C" shape. A cylinder 72 is fixedly installed on one side of the fixed frame 71, and the output end of the cylinder 72 penetrates through the guide plate 51 and extends to be fixedly connected with a scraping block 73. The scraping block 73 is slidably arranged inside the lower die 52, which is convenient for scraping impurities inside the lower die 52.

[0033] Furthermore, a water guide strip 8 is fixedly arranged on the upper surface of the base 1, the water guide strip 8 is located on one side of the guide block 2, and a water guide groove 9 is opened on the upper surface of the water guide strip 8, and the water guide groove 9 is arranged in an arc shape, which is convenient for discharging the removed impurities.

[0034] Secondly, a limit block 10 is fixedly arranged at the upper end of the guide rod 4, which can limit the guide plate 51.

[0035] Furthermore, the upper surface of the guide block 2 and the bottom surface of the lower mold 52 are inclined to facilitate stable interlocking and to facilitate the drainage and removal of cleaned impurities.

[0036] like Figures 1 to 3 As shown, the upper surface of the guide block 2 is provided with a guide groove 11, and the bottom surface of the lower mold 52 is fixedly provided with a sealing pressure block 12 corresponding to the guide groove 11, which can make the guide block 2 and the lower mold 52 seal and snap together.

[0037] In addition, a set of mounting blocks 13 are fixedly installed on both sides of the base 1 to facilitate the stable installation of the base 1 and prevent shaking.

[0038] The working principle of this embodiment is as follows: When die-casting the bracket, pressure is applied to the guide plate 51 through the upper mold. The initial position of the through hole 53 on the lower mold 52 is tightly inserted with the sealing post 3 on the guide block 2, thereby forming a sealed space inside the lower mold 52. An appropriate amount of die-casting material is added to the inside of the lower mold 52 through the injection hole of the upper mold. After adding the appropriate amount of material, the upper mold applies pressure to the lower mold 52. During the movement of the lower mold 52, the guide plate 51 moves down on the outer wall of the guide rod 4 and pushes the spring 6 to contract, thereby die-casting the die-casting material added to the inside of the lower mold 52 to form the automobile bracket.

[0039] After the support is formed, the upper mold moves upward, and the lower mold 52 also moves upward, causing the through hole 53 on the lower mold 52 to move out of the sealing post 3. The die-cast car support is then removed. After removal, the lower mold 52 is cleaned by rinsing its interior with water. During rinsing, the cylinder 72 is activated, and its output drives the scraper 73 to slide horizontally inside the lower mold 52, scraping away residual release agent and various impurities. The scraped-off material is then guided downward through the through hole 53 by water flow and falls into the guide groove 11 on the upper surface of the guide block 2. From there, it slides down into the guide channel 9 on the water guide strip 8 and is discharged. This quick and effective scraping removes residual release agent and various impurities from the mold, preventing prolonged adhesion of the release agent and corrosion of the base, effectively extending the overall service life of the die-casting base, maintaining its good working condition, and ensuring the smooth progress of subsequent die-casting tasks.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
