Embodiment 1

[0028] A sand core hanging nose fixing structure, the sand core hanging nose fixing structure 10 is used in conjunction with the sand core mold in the form of a loose block, and is arranged between the sand core upper mold and the sand core lower mold; the sand core hanging nose structure is used for Fixing the sand core hanging nose, including: fixing seat 110, positioning structure 120; the fixing seat 110 is used to fix the sand core hanging nose; On the sand core mould, a groove is provided on the opposite end face of the fixing seat 110 connected to the positioning structure 120, the depth of the groove is greater than or equal to 20 mm, and the width of the groove is 1 mm to 2 mm larger than the cross-sectional diameter of the sand core hanging nose; At least one installation hole 111 is arranged on the inner wall of the bottom of the groove, and a magnet is installed in the installation hole 111, and the sand core suspension nose is fixed by the magnetic force of the mag...

Embodiment 2

[0041] Different from Embodiment 1, the lower mold positioning structure 121 includes a lower mold positioning structure a1211 and a lower mold positioning structure b1212, and the lower mold positioning structure a1211 and the lower mold positioning structure b1212 are respectively arranged on both sides of the fixing seat 110. This further accurately locates the position of the sand core suspension nose.

Abstract

The invention belongs to the field of the foundry industry, and particularly relates to a sand core hanging nose fixing structure and a use method thereof. The sand core hanging nose fixing structurecomprises a fixing base and a positioning structure. The fixing base is used for fixing a hanging nose. The positioning structure is connected with the fixing base in a lap joint manner or a fixed manner. The positioning structure is installed on a sand core mold. A groove is formed in the end face, opposite to the end face connected with the positioning structure, of the fixing base in a concavemanner. At least one installation hole is formed in the inner wall of the bottom of the groove. A magnet is installed in each installation hole. The sand core hanging nose fixing structure is easy tooperate, easy to take out and high in universality.

Description

technical field [0001] The invention belongs to the field of foundry industry, and in particular relates to a sand core hanging nose fixing structure and an application method thereof. Background technique [0002] In the sand core production process, when the weight of the sand core is ≥15Kg, in order to facilitate the process of turning, lifting, coating and core assembly of the sand core, it is necessary to design a sand core hanging nose on the sand core. At the same time, in order to ensure that the sand core remains horizontal during the lifting and core assembly process, the design of the sand core lifting nose must pass through the center of gravity of the sand core. It is installed on the surface of the core head of the sand core, so in the production process of the sand core, it is very inconvenient to locate and install the suspension nose of the sand core, so that the installation position of the suspension nose cannot be effectively guaranteed, resulting in spec...
