[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] As Figures 1-6 shown, a high-precision casting mold for automotive parts includes a lower automotive casting mold 1. A lifting frame 2 is fixedly installed on the side of the lower automotive casting mold 1. Limit rods 3 are fixedly installed at positions near the four corners on the upper surface of the lower automotive casting mold 1. An upper automotive casting mold 4 is sleeved on the upper ends of the limit rods 3. A support plate 5 is fixedly installed at a position near the lower end on the side of the upper automotive casting mold 4. The lifting frame 2 makes it easier for automotive parts to be automatically demolded from the casting mold, which is beneficial for subsequent clamping by a robotic arm. The support plate 5 can support the upper automotive casting mold 4 to prevent the upper automotive casting mold 4 from suddenly pressing down during the maintenance of the lower automotive casting mold 1 and the upper automotive casting mold 4, playing a safety protection role and not affecting subsequent processing of automotive parts.

[0024] The lifting frame 2 includes a C-shaped frame 201, an electric motor 202, a limiting strip 203, an internally threaded cover 204, a screw rod 205, a bending plate 206, a lifting plate 207 and a movable chuck 208; the C-shaped frame 201 is fixedly installed on the side of the lower automotive casting mold 1, the electric motor 202 is arranged inside the C-shaped frame 201, the limiting strip 203 is fixedly installed on the outside of the electric motor 202, and the part of the limiting strip 203 away from the electric motor 202 is clamped into the groove inside the C-shaped frame 201; the internally threaded cover 204 is fixedly installed on the upper surface of the C-shaped frame 201, the screw rod 205 is arranged in the threaded through hole of the internally threaded cover 204, the bending plate 206 is arranged in the bending through hole on the upper surface of the internally threaded cover 204, the lifting plate 207 is fixedly installed at the upper end of the bending plate 206, the movable chuck 208 is arranged in the through hole at the rear end of the lifting plate 207, and the upper end of the screw rod 205 is fixedly connected to the movable chuck 208; the support plate 5 includes a fixed pipe sleeve 501, a C-shaped plate 502, a guide rail through hole 503, a limiting slider 504 and a telescopic spring 505; the fixed pipe sleeve 501 is fixedly installed at the lower position on the side of the upper automotive casting mold 4, the C-shaped plate 502 is arranged inside the fixed pipe sleeve 501; the guide rail through hole 503 is opened at the lower position near the side of the C-shaped plate 502, the limiting slider 504 is arranged inside the guide rail through hole 503, the telescopic spring 505 is fixedly installed on the upper surface of the limiting slider 504, and the upper end of the telescopic spring 505 is fixedly connected to the inside of the guide rail through hole 503.

[0025] It should be noted that the present utility model is a high-precision casting mold for automotive parts. When in use, the lower automotive casting mold 1 and the upper automotive casting mold 4 are installed and fixed. After the automotive parts are formed, in the lifting frame 2, the electric motor 202 drives the screw rod 205 to rotate. The electric motor 202 slides inside the C-shaped frame 201, and the bending plate 206 slides in the bending through hole on the upper surface of the internally threaded cover 204. The bending plate 206 prevents the lifting plate 207 from rotating. The lifting plate 207 rises and falls as the screw rod 205 rotates, lifting the formed automotive parts, facilitating the clamping by the robotic arm. The lifting frame 2 makes it easier for the automotive parts to be automatically demolded from the casting mold, which is beneficial for the subsequent clamping by the robotic arm. In the support plate 5, the C-shaped plate 502 plays a supporting role, facilitating the maintenance of the lower automotive casting mold 1 and the lifting frame 2. When reprocessing, rotate the C-shaped plate 502 inside the fixed pipe sleeve 501, pull up the limiting slider 504 inside the guide rail through hole 503, and the telescopic spring 505 is compressed until the front end of the limiting slider 504 is inserted into the through hole on the side of the upper automotive casting mold 4. The support plate 5 can support the upper automotive casting mold 4, preventing the upper automotive casting mold 4 from suddenly pressing down during the maintenance of the lower automotive casting mold 1 and the upper automotive casting mold 4, playing a safety protection role and not affecting the subsequent processing of automotive parts.
