Integrated sand core feeding and discharging device for drying room

Abstract

The invention discloses an integrated sand core feeding and discharging device for a drying room, and relates to the technical field of cast molding core treatment. The device comprises more than two core storing channels which are formed in parallel, and flowing and rotating channels which are connected with core feeding channels, wherein two ends of each core storing channel are respectively connected with the core feeding channels and core discharging channels; the flowing and rotating channels are parallel to the core storing channels; the flowing and rotating channels, the core feeding channels, the core storing channels and the core discharging channels are the same in the structure and respectively comprise brackets; tracks are arranged on the brackets; sand core trays are arranged on the tracks; sand core tray jacking mechanisms are respectively arranged at the inlet ends of the flowing and rotating channels, the core feeding channels, the core storing channels and the core discharging channels; the sand core trays in which sand cores are placed are promoted by the sand core tray jacking mechanisms to sequentially enter the flowing and rotating channels, the core feeding channels and the core storing channels, then the sand cores are taken out from the core discharging channels, and the empty trays are pushed to the flowing and rotating channels. The device is simple in structure, convenient to operate and high in working efficiency, and can be used for guaranteeing the drying quality and lightening the working intensity of a worker.

Description

technical field [0001] The invention relates to the technical field of casting core processing. Background technique [0002] The sand core is used to form the inner cavity of the casting, the hole and the part of the casting that cannot produce sand. In the production process of cast pipe, the complex shape and size of the inner cavity of the cast pipe socket are realized by using sand molds. The production process includes: storage, sand mixing, core making, brushing, drying, etc. Sand molds and sand cores can be dried to increase their strength and air permeability, reduce the amount of gas generated during the pouring process, and ensure the quality of castings. The process of storage, sand mixing and core making in the existing equipment has been automated. The document "Centrifugal Ductile Iron Pipe Process and Equipment" P240-256 introduces the manufacturing process and equipment of the sand core in detail. However, there is no research on the process and device for...

AI Technical Summary

Problems solved by technology

This method mainly has the following disadvantages: ① It is impossible to realize automatic entry and exit of sand cores; ② The stacking level of sand cores is limited; ③ Sand cores cannot be first in first out, and some cores will be stored for too long; ④ Labor intensity of workers Large, harsh working environment and easy to cause damage to the sand core

However, the current general mold assembly line production process is mainly suitable for single or few sand core specifications, and cannot meet the transportation requirements of mold sand cores of various specifications. For the production of multi-specification sand cores, the transportation efficiency and reliability sex is difficult to guarantee
