Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0029] see Figure 1 to Figure 8 , an embodiment provided by the present invention: a casting device for preventing cracks at the gate root of a high-alloy steel casting, including a bracket 1, the bracket 1 includes a hexagonal prism rod 101, a cross brace frame 102 and a vertical brace frame 103, The whole bracket 1 is composed of two T-shaped struts on the left and right symmetrically welded, and a cross-bracing beam is welded on the upper half of the two T-shaped struts. Ring 5; a hexagonal prism rod 101 is welded between the bottom cross brace connecting rod of the bracket 1 and the middle section of the top cross brace beam rod, and a cross brace frame 102 is w...

The invention discloses a casting device for preventing cracks at the root of the inner gate of a high-alloy steel casting, relates to the technical field of casting equipment, and solves the problem of manually pouring heated cooling water and manually supplementing cooling in the existing casting device Water, the operation and use are more cumbersome, laborious and inconvenient, and the practicability is not good. A casting device for preventing cracks at the root of the inner gate of a high-alloy steel casting, including a bracket, the bracket includes a hexagonal prism rod, a horizontal brace frame and a vertical brace frame, and the whole bracket is symmetrical with two T-shaped braces on the left and right It is composed of welding, and a cross-bracing beam is welded on the upper half of the two T-shaped struts; a hexagonal column is welded between the bottom cross-bracing connecting rod of the support and the middle section of the top cross-bracing beam. In the present invention, after the inner mold slides away from the outer mold, the driven gear can engage with the rack and drive the inner mold to rotate one circle to discharge the heated cooling water at the top, which saves the trouble of manually turning over and pouring out hot water.
Description
technical field [0001] The invention relates to the technical field of casting equipment, in particular to a casting device for preventing cracks at the root of a gate in a high-alloy steel casting. Background technique [0002] Alloy steel castings have high casting performance requirements, strict non-destructive testing requirements, and are required to be free from casting defects such as slag inclusions, shrinkage porosity, and cracks. In the traditional casting process of high-alloy steel castings, the area at the root of the ingate is always in a high temperature state during pouring, which leads to slow heat dissipation during the sequential solidification process, and the tendency of hot cracking, which in turn produces hot cracks, which seriously affects the cast steel. Therefore, it is necessary to design a casting device that prevents cracks at the root of the gate in high-alloy steel castings. [0003] For example, the patent with the patent number CN2019105189...
