Problems solved by technology

However, for parts with complex structures, such as the base part mold of Inner Mongolia Lectra Company, the internal cavity of the part has 2 ribs with a thickness of 2*74mm, 4 grooves of 4*78, and 2 square holes of 4*20. The part drawing These required geometric dimensions are extremely difficult to make in foundry molding. For the actual characteristics of the part, it can only be completed by using the coated sand core shooting process and using the hot core machine.
However, the size of the existing hot core machine is very large, and the mold size is too small to match the existing hot core machine, so it is necessary to redesign a mold with the processing size of the hot core machine

Abstract

The invention provides a miniature hot-box core shooter. The miniature hot-box core shooter comprises a frame, a heating member, an upper mold and a lower mold. The upper mold and the lower mold are coupled and are arranged in the frame, the heating member comprises a heating chamber, a heating part and control buttons, the heating chamber is movably arranged to the top of the frame, the heating part is arranged in the heating chamber and the control buttons are electrically connected to the heating part. Compared with the existing hot-box core shooter, the miniature hot-box core shooter has a function of automatic heating, realizes manual control mold heating, is suitable for molds with various sizes and has a fast part preparation rate.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a miniature hot core machine. Background technique [0002] At present, in the domestic foundry industry, many enterprises will use hot core machines when making sand cores. However, for parts with complex structures, such as the base part mold of Inner Mongolia Lectra Company, the internal cavity of the part has 2 ribs with a thickness of 2*74mm, 4 grooves of 4*78, and 2 square holes of 4*20. The part drawing These required geometric dimensions are very difficult to make in foundry molding, and the actual characteristics of the part can only be completed by using the coated sand core shooting process and using the hot core machine. However, the size of the existing hot core machine is very large, and the mold size is too small to match the existing hot core machine, so it is necessary to redesign a mold with the processing size of the hot core machine.
