Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal casting, and in particular to a casting model structure for a single riser in a small clamp body. Background Technology
[0002] Automobiles play a vital role in current social development and human life. Braking performance is a key indicator of vehicle quality, and the quality of brake components is paramount among all automotive parts. The caliper body is a crucial component in the braking system, connecting the brake pads and providing the tightening force during braking; therefore, it requires excellent mechanical properties and strict defect requirements. To save costs, most passenger car caliper bodies are currently produced using a single riser casting process. However, the single riser casting process presents the following difficulties:
[0003] 1. The two-layer through riser has a large flow rate, which leads to severe sand erosion. This results in appearance and internal sand defects in the product, affecting the durability of the parts.
[0004] 2. A large flow path size results in a close proximity to the earpiece. The insulation effect of the flow path leads to low hardness of the caliper earpiece, making it prone to breakage during use, causing brake failure and potentially resulting in an irreparable traffic accident.
[0005] 3: When the upper and lower risers are located on the same vertical line, heat concentration will cause internal shrinkage and porosity in the casting, which will also cause brake failure or reduced durability. Utility Model Content
