Abstract

This utility model discloses a core-removing gripper for subframe castings, including a casting table. Gripping frames are fixedly installed on both sides of the casting table, and robot mounting ports are opened in the middle of each gripping frame. Gripping components are engaged and installed inside both robot mounting ports. Each gripping component includes a locking post, a motor housing, a servo motor, a rotating shaft, a height platform, a lifting cylinder, and a clamping mechanism. This utility model's core-removing gripper for subframe castings, by setting up gripping components, is used to remove castings from the low-pressure press and to insert cores into the mold. After a mold is formed, the gripping component is installed on the casting table via the locking post, and then, through the clamping mechanism, inserts the core into the low-pressure press and removes the casting. After completing these two actions, it retracts and places the casting on an outer tray, replacing traditional manual material handling. The operation is simple, convenient, time-saving, and labor-saving.

Description

Technical Field

[0001] This utility model relates to the field of subframe casting preparation technology, specifically a core removal gripper for subframe castings. Background Technology

[0002] High-pressure casting subframes utilize high-pressure casting technology, injecting molten metal into a mold under high pressure. This results in a higher density and more uniform structure, giving the subframe high strength and durability, capable of withstanding various forces and vibrations during vehicle operation. Compared to traditional subframe manufacturing methods, high-pressure casting subframes employ a lightweight design. By optimizing the structure and reducing material usage, the weight of the subframe is significantly reduced. This not only improves fuel economy but also reduces environmental impact, hence the widespread production of subframe castings. However, traditional subframe casting manufacturing has the following drawbacks: In the traditional process of manufacturing subframe castings, manual handling of the product inside the mold is still required. If the product cooling time is too short, it can easily lead to safety accidents such as high-temperature burns and mechanical injuries. Improper operation may result in serious work-related injuries. If the product cooling time is too long, it reduces the manufacturing efficiency of subframe castings. Utility Model Content
