Problems solved by technology

However, except for the cavity part of the casting, the casting mold has always been a solid and dense structure. After the casting is solidified, the cooling efficiency of the sand mold is very low, resulting in a long production cycle for large castings. Casting structure for real-time control and monitoring

Embodiment Construction

[0012] The new non-compact structure mold of the present invention will be described in detail below with reference to the accompanying drawings.

[0013] refer to figure 1 , according to the new non-dense structure of the present invention, the mold includes: a mold shell 1, which is provided with a cavity 11 for casting molding and a temperature control channel 12 leading to a temperature control medium; a pouring system 2, integrally formed with the mold shell 1, The melt for the casting flows into the cavity 11 of the mold shell 1; the truss structure 3 is located outside the mold shell 1 and connected to the mold shell 1 to fix and support the mold shell 1; the sensor 4 is arranged on the mold shell 1.

[0014] In the new non-compact structure mold according to the present invention, the mold formed by the shell 1 and the truss structure 3 replaces the original solid compact structure (that is, the shell 1 is a thin-walled structure compared to the original solid compact ...

Abstract

The invention provides a non-compact structured new casting mold. The non-compact structured new casting mold comprises a mold shell, a casting system, a truss structure and a sensor, wherein a molding cavity for molding a casting and a temperature control channel for feeding in a temperature control medium are arranged in the mold shell; the casting system is integrally molded with the mold shell, and enables molten liquid of the casting to flow in the molding cavity of the mold shell; the truss structure is positioned out of the mold shell, and is connected with the mold shell for fixing and supporting the mold shell; and the sensor is arranged on the mold shell. the casting mold consisting of the mold shell and the truss replaces a traditional solid compact structure, so that the use level of molding sand is largely reduced, the material is saved, the environmental pollution in the molding sand treatment process is reduced, and the effects of energy conservation and environmental protection are achieved; the heat dissipation of the mold shell is fast, and the cooling efficiency of the casting is high; the sensor can monitor the strain change of temperature or stress of corresponding parts in the casting molding process, and controls the flow and the temperature of a temperature control medium in the temperature control channel according to detected signals; and through effective temperature control of the temperature control medium by the sensor, quick and balanced cooling of the casting is realized, the structure of the casting is improved, the residual stress and deformation of the casting are reduced, and the performance of the casting is improved.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a new non-compact structure casting mold. Background technique [0002] In the casting process, the casting mold is the guarantee for the forming of the casting. Factors such as the shape, size, and thickness of the casting mold will affect the temperature field, velocity field, stress field and strain during the solidification process of the casting, thereby affecting the structure and structure of the casting. performance. However, except for the cavity part of the casting, the casting mold has always been a solid and dense structure. After the casting is solidified, the cooling efficiency of the sand mold is very low, resulting in a long production cycle for large castings. Real-time control and monitoring of the mold structure. Contents of the invention [0003] In view of the problems existing in the background technology, the object of the present invention is to provid...
