Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a cold iron device for improving the performance of workbench castings. Background Art

[0002] Chill refers to a chill placed inside the cavity, on the cavity surface and inside the mold to speed up the local cooling rate of the casting. Chill is used in conjunction with the pouring system and the riser system to control the solidification sequence of the casting to obtain qualified castings. Chill is divided into internal chill and external chill. The casting must undergo three shrinkage processes: liquid shrinkage, solidification shrinkage and solid shrinkage, which often leads to shrinkage or shrinkage holes in the last solidified part of the casting. The appearance of shrinkage and shrinkage holes not only greatly reduces the mechanical properties of the casting, but also reduces the density of the casting so that it cannot meet the quality of the casting with pressure-resistant sealing requirements.

[0003] According to announcement number CN215786563U, an external cooling iron device is provided, including: a sand box, a cooling pipe, a cooling head, and a positioning device. The sand box is used to store molding sand, and a side plate is provided on the side of the sand box; the cooling pipe is passed through the side plate, and the cooling pipe is used to circulate the cooling medium; the cooling head is connected to one end of the cooling pipe and is located in the sand box, and the cooling head can move with the cooling pipe. A cavity for the circulation of the cooling medium is provided inside the cooling head, and the positioning device is connected to the side plate to fix the position of the cooling pipe. The utility model provides an external cooling iron device, in which the cooling pipe passes through the side plate to pass the cooling medium into the cooling head. During installation, the cooling pipe is passed through the side plate, the position of the cooling head in the sand box is adjusted, and then the positioning device is used to fix the cooling pipe, so that the cooling head is fixed. During installation, the cooling head is easy to install, and the positioning and fixing methods are reliable, which can effectively improve the quality of large castings.

[0004] This patent realizes the installation, positioning and fixing of the cooling head, and connects the cooling device to the sand box by bolts and multiple pins. However, when the cooling device is installed and fixed, due to its heavy weight, the staff is required to support the cooling device first, and then install the pins and positioning sleeves in sequence, which increases the time consumption of the installation of the cooling device. In addition, the cooling device is heavy and long, which causes the center of gravity of the cooling device after installation to be located at one end of the sand box. During the use of the cooling device, the cooling device tends to tilt toward one end of the sand box, thereby affecting the stability of the use of the cooling device. For this purpose, a cold iron device for improving the performance of workbench castings is provided. Utility Model Content
