Casting mold and box closing method

Abstract

The invention relates to a casting mold. The casting mold comprises a lower sand mold body, an upper sand mold body connected with the lower sand mold body and a core arranged in the lower sand mold body, wherein the core comprises a core mark contained in a core mark pit of the upper sand mold body. The casting mold further comprises a mold cone arranged between the lower sand mold body and the upper sand mold body. The upper sand mold body comprises a first mold cone pit used for containing the mold cone. The mold cone is in contact with the inner wall of the first mold cone pit. The core mark and the inner wall of the core mark pit are spaced. The casting mold and the mold assembling method for solving the problem of sand rubbing of the core mark are provided for overcoming the defect that the sand rubbing risk exists in the mold assembling process of a core of a special structure in the prior art, the problem that the core mark is prone to sand rubbing is effectively solved, field operation can be more convenient, and the quality of a casting is ensured more easily. The invention further relates to the mold assembling method.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting mold and a box closing method. Background technique [0002] In the resin sand casting process, in order to fix the core and ensure that the core can be placed in the proper position of the cavity during the core setting process, and the core will not move during the pouring and solidification process, it is necessary to make a core on the core. The head is used to achieve this purpose through the cooperation of the core head and the sand mold. Normally, the core heads of the core are all in the same sand mold, and the core is pressed by the core, the sand mold is used to press the core, or the auxiliary tooling is used to fix it. The loose sand that enters the cavity can be found and processed in time, and the risk of sand inclusion in the casting is small; the core positioning is accurate, the dimensional accuracy of the casting is high, and the quality is easy to guarantee. ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the disadvantages of the risk of rubbing sand in the process of boxing the special structure core in the prior art, and provides a casting mold and box closing method to solve the sand rubbing of the core head, which effectively solves the problem of the sand rubbing of the core head and makes the On-site operation is more convenient, and the quality of castings is easier to guarantee
