A cast iron fixed grid structure with good heat dissipation effect

Abstract

The invention discloses a fixed grid structure of cast iron parts with good heat dissipation effect, which comprises an upper support, legs are welded at the four corners of the lower end of the upper support, universal wheels are installed at the lower ends of the legs, and The lower ends of the outriggers extend outward and are riveted with a connecting seat, and a screw is movable inside the connecting seat, and a backstop is welded at the lower end of the screw, and lower cross braces are respectively welded from bottom to top between adjacent legs And the upper cross brace, an installation groove is opened at the middle position of the upper end surface of the upper cross brace, a cooling box is placed in the installation groove, and a water outlet pipe is extended upward on one side of the cooling box. The fixed grid structure of cast iron parts with good heat dissipation effect described in the present invention is designed with a cooling water tank, and the cooling water is used to circulate in the water tank to take away the heat on the surface of the mold. Such circulation can significantly improve the heat dissipation of the iron casting mold Effect, suitable for different working conditions, bringing better prospects for use.

Description

technical field [0001] The invention relates to the technical field of iron castings, in particular to a fixed grid structure for iron castings with good heat dissipation effect. Background technique [0002] Articles cast with molten iron are collectively called iron castings. Due to various factors, iron castings often have defects such as pores, pinholes, slag inclusions, cracks, and pits. The commonly used repair equipment is argon arc welding machine, resistance welding Welding machine, cold welding machine, etc. For casting defects that do not require high quality and appearance, they can be repaired by welding machines with high heat generation and fast speed such as argon arc welding machines; existing iron castings need to use grids when casting, which is convenient Fixing and pouring of cast iron molds, but the current grid only relies on heat dissipation nets to dissipate heat, the cooling effect is not good, and because of the installation of pulleys, the entire ...

[0002] Articles cast with molten iron are collectively called iron castings. Due to various factors, iron castings often have defects such as pores, pinholes, slag inclusions, cracks, and pits. The commonly used repair equipment is argon arc welding machine, resistance welding Welding machine, cold welding machine, etc. For casting defects that do not require high quality and appearance, they can be repaired by welding machines with high heat generation and fast speed such as argon arc welding machines; existing iron castings need to use grids when casting, which is convenient Fixing and pouring of cast iron molds, but the current grid only relies on heat dissipation nets to dissipate heat, the cooling effect is not good, and because of the installation of pulleys, the entire grid is unstable during work, which brings certain disadvantages during use Therefore, we propose a cast iron fixed grid structure with good heat dissipation effect
