Description

Technical Field

[0001] This utility model relates to the field of die casting molds, and in particular to a core-pulling structure inside a steering gear housing mold. Background Technology

[0002] The automotive steering gear is the core component of a vehicle's steering system, responsible for converting the rotational motion of the steering wheel into the steering action of the wheels. The steering gear housing houses the core components such as the steering gear gears, rack, and bearings, and withstands steering forces and vibrations. The die-casting process for the steering gear housing must balance structural complexity, dimensional accuracy, and material properties. Due to the product structure and the unsuitable stud locking holes, a core-pulling structure is employed. However, conventional core-pulling structures use inclined guide pillars or similar mechanisms for drive, requiring significant space. Given the limited space within the mold, a core-pulling structure with a locking pin is needed. Utility Model Content

[0003] To address the shortcomings of the existing technology, the main objective of this utility model is to overcome these deficiencies and disclose a core-pulling structure for a steering gear housing mold, comprising a support block, a core puller, a connecting rod, and an actuator. The support block is mounted on a fixed mold and has a through guide hole. The connecting rod is slidably connected to the guide hole. The actuator is mounted outside the fixed mold via a bracket. The actuator is connected to the core puller via the connecting rod. Two support blocks are arranged in parallel to form a guide rail for the moving mold.

[0004] Furthermore, it also includes a guide sleeve, which is disposed within the fixed mold, and the core puller is slidably connected to the guide sleeve.

[0005] Furthermore, the core puller is engaged and fixed with the connecting rod.

[0006] Furthermore, one end of the connecting rod is provided with a radially recessed groove, and one end of the core puller is provided with a radially protruding edge. During assembly, the edge is placed in the groove.

[0007] Furthermore, it also includes a cooling assembly, wherein the core-pulling mechanism is axially provided with a cooling cavity, and the cooling assembly is connected to the cooling cavity.

[0008] Furthermore, the cooling assembly includes an inlet pipe, a return pipe, and a connector. The inlet pipe is disposed inside the return pipe, and the inlet pipe, the return pipe, and the connector are connected to the connector. The connector is provided with a connector for connecting the inlet pipe and the return pipe.

[0009] Furthermore, the sidewall of the connecting rod is radially recessed to accommodate the cooling assembly.

[0010] Furthermore, the actuator is a hydraulic cylinder.

[0011] Furthermore, the side plate of the support block is provided with an oil groove.

[0012] The beneficial effects obtained by this utility model are:

[0013] This invention places the actuator externally, reducing the space required inside the mold, and achieves long-distance driven core-pulling movement by setting support blocks. Two parallel support blocks form a guide groove to guide the opening and closing movement of the moving mold, further improving the utilization rate of the mold's internal space. A cooling component is included to achieve rapid cooling and solidification of the core-pulling part, avoiding shrinkage holes. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] A core-pulling structure within a steering gear housing mold, such as Figures 1-6As shown, the system includes a support block 1, a core puller 2, a connecting rod 3, and an actuator 4. The support block 1 is mounted on the fixed mold 8 and has a through guide hole 11. The connecting rod 3 is slidably connected to the guide hole 11. The actuator 4 is mounted outside the fixed mold 8 via a bracket to externalize the drive assembly, thereby reducing the space required inside the mold. The actuator 4 is connected to the core puller 2 via the connecting rod 3. Two support blocks 1 are provided, arranged parallel to each other, forming a guide groove between them to guide the opening and closing of the moving mold, further improving the utilization rate of the internal space of the mold. Externalizing the actuator 4 requires long-distance drive; to ensure stable movement of the core puller 2, the connecting rod 3 is supported by the support block 1.

[0024] Furthermore, such as Figures 1-6 As shown, it also includes a guide sleeve 5, which is disposed within the fixed mold 8, and the core puller 2 is slidably connected to the guide sleeve 5. The guide sleeve 5 supports and guides the core puller 2.

[0025] In one embodiment, such as Figures 1-6 As shown, the core puller 2 is snapped and fixed to the connecting rod 3.

[0026] In the above embodiments, such as Figures 1-6 As shown, one end of the connecting rod 3 is provided with a radially recessed groove 31, and one end of the core puller 2 is provided with a radially protruding flange 21. During assembly, the flange 21 is placed in the groove 31.

The cooling assembly 6 is connected to the cooling chamber 22. This cools the core-pulling part 2, thereby promoting the cooling of the core-pulling feature part of the die-cast product and promoting the qualitative cooling of the product.

[0028] In one embodiment, such as Figures 1-6 As shown, the cooling assembly 6 includes an inlet pipe 61, a return pipe 62, and a connector 63. The inlet pipe 61 is disposed inside the return pipe 62. The inlet pipe 61 and the return pipe 62 are connected to the connector 63. The connector 63 is provided with a connector 64 that connects to the inlet pipe 61 and the return pipe 62. The connector 64 connects to an external circulating cooling system, which is a conventional device and will not be described in detail here. Coolant is sent into the cooling chamber 22 of the core extractor 2 through the inlet pipe 61. A return channel is formed between the return pipe 62 and the inlet pipe 61, and the coolant flows back to the circulating cooling system through the connector 64. In this embodiment, the inlet pipe 61 extends into the cooling chamber 22.

[0029] In one embodiment, such as Figures 1-6 As shown, the side wall of the connecting rod 3 is radially recessed with a mounting groove 32 to accommodate the cooling component 6. This serves to protect the cooling component 6. At the same time, the connecting rod 3 is supported by the support block 1, and the connecting rod 3 drives and guides the movement of the core puller 2.
