Description

Furnace door structure of precision casting furnace Technical Field The utility model relates to the technical field of forging furnaces, in particular to a furnace door structure of a precision casting furnace. Background In the field of vacuum precision casting furnaces in China at present, a rocker arm type furnace door structure which is manually opened and closed is adopted for the furnace door structure design of equipment, and the furnace door structure is similar to a door opening and closing structure in home. The structure has the following defects that the inside of the vacuum precision casting furnace is a high-temperature working environment, the inside of the furnace door also has high temperature, if the furnace door is manually opened, operators have risk of scalding, the rocker arm type rotary door opening mode can occupy the front space of the furnace door, and the equipment occupies large space. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide a furnace door structure of a precision casting furnace. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model discloses a furnace door structure of a precision casting furnace, which comprises a door frame and a furnace door, wherein a hinge is arranged on the furnace door, a linear sliding rail is arranged on the door frame, a sliding block is arranged on the linear sliding rail in a sliding manner, one end of the hinge, which is far away from the furnace door, is arranged on the sliding block, a translation cylinder mounting seat is arranged on the door frame, a translation cylinder is arranged on the translation cylinder mounting seat, a pull plate is connected to a piston rod of the translation cylinder, and the pull plate is arranged on the sliding block. Further, the left side and the right side of the furnace door are both provided with furnace door tensioning seats, and the inner sides of the furnace door tensioning seats are provided with grooves. Further, the furnace body furnace further comprises two tensioning cylinders arranged on the furnace body, the positions of the two tensioning cylinders are respectively corresponding to furnace door tensioning seats on two sides, the end parts of piston rods of the tensioning cylinders are connected with tensioning blocks, and the tensioning blocks can enter the grooves. Further, a guide rail is arranged on the portal frame and is positioned below the furnace door. Further, the guide rail comprises a support plate which is horizontally arranged, the support plate is positioned under the furnace door, and the front side of the support plate is connected with a limiting plate. Further, the portal includes the stand of vertical setting, and the stand upper end is connected with the horizontal pole, and the front side at the horizontal pole is installed to the linear slide rail, and the guide rail is installed in the front side lower part position of stand.
