Problems solved by technology

[0002] When using a mold to forge or cast a workpiece, due to the low temperature of the mold and the high temperature of the casting melt, it is easy to cause defects such as molding difficulties, mucous membranes, and casting cracks. Large, it is easy to cause damage to the mold, and in severe cases, it will cause the mold to burst. Therefore, the mold must be preheated before use, so that the mold can reach a certain temperature when it is working.
[0003] When the existing preheating device preheats the mold, due to the uneven preheating, the forging quality is affected, the production efficiency is reduced, and the structure of the preheating device is complicated

Abstract

The invention provides a mould preheating device. The mould preheating device comprises a hollow base, a mould supporting shaft for fixing a mould is arranged at the center of the base, the mould supporting shaft sequentially comprises a supporting column, a transition shaft and a rotary shaft from top to bottom, the bottom end and the mid-upper side wall of the rotary shaft are rotatably fixed onthe base , the rotary shaft inside the base is connected with a rotating device, a ring-shaped heating housing is arranged above the mould, the heating housing is internally provided with heating wires, the top surface of the heating housing is fixed on a lifting plate, an electromagnetic heating rod is coaxially arranged at the center of the heating housing, the top end of the electromagnetic heating rod is fixed to an upper heating seat, the upper heating seat is fixed on the lifting plate, a cavity accommodating a lower heating seat is arranged at the center of the mould supporting shaft,the lower heating seat is arranged at the top of the cavity, the lower heating seat is fixed to the bottom surface of the base, the two heating seats serve as electrodes of the electromagnetic heatingrod, and the lifting plate is connected with a lifting device. The mould preheating device is capable of heating the inside wall and the outside wall of the mould at the same time, and the mould heating uniformity is improved.

Description

technical field [0001] The invention belongs to the technical field of mold production equipment, and in particular relates to a mold preheating device. Background technique [0002] When using a mold to forge or cast a workpiece, due to the low temperature of the mold and the high temperature of the casting melt, it is easy to cause defects such as molding difficulties, mucous membranes, and casting cracks. Large, it is easy to cause damage to the mold, and in severe cases, it will cause the mold to burst. Therefore, the mold must be preheated before use to make the mold reach a certain temperature when it is working. [0003] When the existing preheating device preheats the mould, due to the uneven preheating, the forging quality is affected, the production efficiency is reduced, and the structure of the preheating device is complicated. Contents of the invention [0004] In view of this, the present invention aims to propose a mold preheating device to solve the above ...
