Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically an automotive caliper casting mold. Background Technology

[0002] Automotive caliper casting molds are specialized metal tools used for the mass production of automotive brake caliper blanks. Their core function is to inject and shape molten aluminum alloy or cast iron into a precisely designed cavity during the high-pressure casting process, thereby efficiently and consistently producing the initial castings of the calipers. These blanks then undergo machining and surface treatment to become the final product.

[0003] However, in the use of existing automotive caliper casting molds, the connecting parts of the mold are subjected to the clamping force and the impact force of molten metal during the casting process, which easily leads to deformation and affects the service life. Therefore, those skilled in the art have provided an automotive caliper casting mold to solve the problems mentioned in the background art. Utility Model Content

[0024] In one embodiment of this utility model, the stabilizing mechanism 7 includes a stabilizing limiting plate 71, a positioning block 73 embedded and fixed inside the assembly pad 2, one side of the stabilizing limiting plate 71 fitting against the outer side of the lower casting mold 3, a reinforcing plate 72 fixed to the outer side of the stabilizing limiting plate 71, a positioning block 73 provided at the bottom of the stabilizing limiting plate 71, an assembly plate 74 provided at the top of the stabilizing limiting plate 71, a connecting semi-threaded rod 75 installed on one side of the assembly plate 74, an installation semi-threaded rod 76 fixed to the outer side of the lower casting mold 3, and a threaded connecting sleeve 77 threadedly connecting the connecting semi-threaded rod 75 and the installation semi-threaded rod 76. The outer side of the positioning plate 71 is provided with a groove, and the outer side of the threaded connecting sleeve 77 is provided with anti-slip texture, which makes it easy for the user to rotate the threaded connecting sleeve 77. After the lower casting mold 3 and the assembly pad 2 are fixed by bolts, the positioning block 73 at the bottom of the stabilizing limiting plate 71 is inserted into the preset groove of the assembly pad 2. At this time, the connecting half-threaded rod 75 on the outer side of the stabilizing limiting plate 71 can form a complete threaded rod with the mounting half-threaded rod 76 on the outer side of the lower casting mold 3. The threaded connecting sleeve 77 can be used to fix the connecting half-threaded rod 75 and the mounting half-threaded rod 76. The stabilizing limiting plate 71 can limit and reinforce the outer side of the lower casting mold 3.

[0025] The working principle of this utility model is as follows: This device is equipped with an anti-loosening mechanism 6. After the upper mold connecting plate 4 and the upper casting mold 5 are fixedly connected, one side of the metal mounting plate 62 at the bottom of the support connecting pad 61, which is welded and fixed to the upper casting mold 5, can be attached to the outside of the upper mold connecting plate 4. At this time, the rotating plate 612 on the outside of the metal connecting column 611 can be rotated, and one side of the rotating plate 612 can be attached to the outside of the metal mounting plate 62. The rotating sleeve 614 can be placed on the outside of the high-temperature threaded rod 613 and rotated clockwise. The corresponding rotating sleeve 614 has one side that can fit against the outside of the rotating plate 612, which can easily fix the rotating plate 612 to the metal mounting plate 62. At the same time, it can push the anti-disengagement slider 65 to slide in the groove of the fixed limit sleeve 64. The movable sleeve 67 outside the anti-disengagement slider 65 is fitted onto the outside of the high-temperature bolt 63, and the high-temperature nut 69 is rotated clockwise to fix the movable sleeve 67 and the metal mounting plate 62, thereby ensuring a stable connection between the metal mounting plate 62 and the upper mold connecting plate 4. When the upper casting mold 5 pushes and presses the upper mold connecting plate 4 vertically, the supporting connecting pad 61 and the metal mounting plate 62 can share some of the pressure and improve the pressure resistance of the connection between the upper mold connecting plate 4 and the upper casting mold 5. This can significantly increase the section modulus and bending stiffness of the area, effectively resist the impact pressure of the mold closing force and molten metal, and reduce the elastic deformation and creep of the mold under high pressure. The device is equipped with a stabilizing mechanism 7. After the lower casting mold 3 and the mounting pad 2 are fixed by bolts, the positioning block 73 at the bottom of the stabilizing limiting plate 71 is inserted into the preset groove of the mounting pad 2. At this time, the connecting half-threaded rod 75 on the outside of the stabilizing limiting plate 71 can form a complete threaded rod with the mounting half-threaded rod 76 on the outside of the lower casting mold 3. The threaded connecting sleeve 77 can be used to fix the connecting half-threaded rod 75 and the mounting half-threaded rod 76. The stabilizing limiting plate 71 can limit and reinforce the outside of the lower casting mold 3, ensuring the stability of the lower casting mold 3 installation and avoiding the situation of insufficient stability and positional deviation of the lower casting mold 3 installation.
