Abstract

The invention relates to a high-strength film-coated sand core for sand casting, a manufacturing machine and a manufacturing process. The core includes a core body, a core bone body, reinforcements, connectors and connecting bolts. A special The manufacturing machine includes a feeding mechanism, a crushing mechanism and a shell, and the feeding mechanism and the crushing mechanism are installed in the shell. The method for making the above-mentioned mold core by using the above-mentioned making machine includes the following steps: coated sand manufacturing, core box manufacturing Core, core trimming and core inspection. The present invention provides a high-strength film-coated sand core for sand casting. The various parts of the mandrel are connected in a detachable manner. After the mandrel is disassembled, the mandrel can be taken out from a narrow space without damage. The structural integrity of the core bone can be realized multiple times.

Description

technical field

[0001] The invention relates to the field of casting, in particular to a high-strength film-coated sand core for sand casting, a manufacturing machine and a manufacturing process. Background technique

[0002] Coated sand mainly uses high-quality selected natural quartz sand as raw sand, thermoplastic phenolic resin, urotropine and reinforcing agent as raw materials, and the proportion can be adjusted appropriately according to different technical requirements of users. One of the best molding materials, it is also often used to make sand casting cores.

[0003] The core is commonly known as "mud core" and "core". It is used to form the internal structure of the casting during casting. The core sand is often made of raw sand and binder. It is made by hand or machine in the core box. In order to strengthen the core The rigidity and strength of the core, often set the core bone in the core. Commonly known as "mud core bone" and "core iron", the core bone is a...
