Description

Technical Field

[0001] This utility model relates to the field of steel shot production technology, and in particular to a steel shot shielding device for a coated sand-embedded steel shot production line. Background Technology

[0002] The coated sand shot embedding production line embeds steel shot into the coated shell mold placed in the sand box at the molding station. During the embedding process, steel shot is prevented from entering the shell core and from damaging the shell mold by falling steel shot. Steel shot entering the shell core or a damaged shell mold can cause irreparable defects to the casting after casting. Therefore, the shell mold needs to be protected during the embedding process.

[0003] The current common method is to manually place the protective cover on top of each mold shell before embedding the steel shot, and then manually remove the protective cover after embedding the steel shot and compacting it. The manual removal and placement of the protective cover requires workers to perform frequent repetitive operations, which is time-consuming and can easily damage the mold shell. It is necessary to plan a storage area for the protective cover, which reduces the workers' workspace.

[0004] To address this issue, we propose a steel shot shielding device for a coated sand-embedded steel shot production line. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel shot shielding device for a coated sand-embedded steel shot production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A steel shot shielding device for a coated sand-embedded steel shot production line includes a supporting base rod, an mounting rod fixedly connected to the top of the supporting base rod, and a rotary cylinder mounted on the top of the mounting rod. The end of the rotary cylinder is connected to one end of a driving connecting rod via a pin, and the other end of the driving connecting rod is hinged to the side of a protective cover. A fixed crossbar is fixedly connected to the top of the protective cover, and both ends of the fixed crossbar are hinged to a driven connecting rod.

[0007] Preferably, the supporting base rod is composed of three square steel bars, which are welded together, and the three supporting base rods are fixed to the ground by expansion bolts.

[0008] Preferably, two mounting rods are welded above the support base rod, and a diagonal brace is welded between the support base rod and the mounting rod.

[0009] Preferably, there are two symmetrically arranged driving links and driven links, and the two driving links and driven links are arranged in parallel.

[0010] Preferably, the length of the fixed crossbar is the same as the surface length of the protective cover.

[0011] Preferably, a cross brace is welded to the upper inner side of the two mounting rods.

[0012] Preferably, the rotary cylinder is mounted on the inside of the mounting rod by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The purpose of this device is to automatically protect the mold shell during steel shot embedding. It uses a drive rod and a driven rod to raise and lower the entire protective cover. The drive rod and driven rod are driven by an angle-adjustable rotary cylinder. After the device lowers to the correct position, it automatically embedding steel shot. Once the steel shot filling is complete, the vibrating table vibrates, completing the vibration process. This saves labor and time, improving efficiency. The device is accurately positioned, preventing damage to the mold shell. It is installed opposite the manual operation position, and the bottom of the protective cover's rain-drenching sand feeder is level with the bottom of the raised position, thus not occupying operating space.
