AI Technical Summary
Existing technologies tend to form shrinkage cavities when die-casting the lifting ring of the gearbox's electronic control side housing, resulting in insufficient structural strength and failing to meet the high-performance requirements of automotive parts.
The design employs a combination of a round-hole core-pulling rod and a spot-cooling tube. The round-hole core-pulling rod reduces the amount of molten metal used, promoting full filling of the cavity gaps with molten metal. The spot-cooling tube accelerates the solidification of the internal molten metal, avoiding shrinkage defects.
It significantly improves the structural strength and reliability of lifting rings, reduces safety hazards, simplifies subsequent processing steps, and increases production efficiency.

Abstract
Claims
1. A die-cast structure of a lifting ring body, characterized by comprising: The device includes a moving mold core, a fixed mold core, and a core-pulling assembly. The moving mold core and the fixed mold core are closed to form a lifting ring cavity. The core-pulling assembly includes a hydraulic cylinder fixed on the moving mold frame, a slider seat connected to the piston rod end of the hydraulic cylinder, and a round-hole core-pulling rod fixedly connected to the slider seat. The round-hole core-pulling rod is inserted from the top of the moving mold core and then extends into the lifting ring cavity. A cooling tube is provided inside the round-hole core-pulling rod.
2. The die-cast structure of a lifting ring body according to claim 1, wherein The moving mold core is provided with a core-pulling sleeve for guiding the movement of the core-pulling rod in the circular hole, and a pressure block for locking the position of the core-pulling sleeve.
3. The die-cast structure of the lifting ring body according to claim 1, wherein The core-pulling rod with a circular hole includes a core-pulling circular head, a flow-blocking rod body, and a stop tail connected in sequence. A blind hole is provided in the middle of the front end face of the core-pulling circular head.
4. The die-cast structure of the lifting ring body according to claim 3, characterized by The slider seat includes an L-shaped seat body and a vertical plate disposed on the front end face of the L-shaped seat body. The end face of the vertical plate facing the L-shaped seat body is provided with a positioning protrusion. The L-shaped seat body is provided with a positioning groove that matches the positioning protrusion. The L-shaped seat body is connected to the vertical plate by screws.
5. The die-cast structure of the lifting ring body according to claim 4, wherein The vertical plate has a countersunk through hole on the end face facing the L-shaped base. The countersunk cavity of the countersunk through hole is adapted to the stop tail. The through hole cavity of the countersunk through hole allows the blocking rod body of the round hole core pull rod to pass through.
6. The body of claim 1 wherein, The hydraulic cylinder is fixed to the moving mold frame by a U-shaped frame, and the end of the piston rod of the hydraulic cylinder is connected to the slider seat through a joint.
7. The body of claim 1 wherein, The moving mold frame is provided with guide strips on the upper and lower sides of the slider seat to guide the slider seat to slide.
