[0001] The utility model relates to the technical field of metal processing, in particular to a preheating device for a metal mold. Background Art

[0002] When using a mold to cast or forge a workpiece, the low mold temperature and high casting melt temperature can easily lead to defects such as molding difficulties, sticking, and casting cracks. Furthermore, due to the significant temperature difference between the low-temperature mold and the high-temperature casting melt, the thermal stress is very large, which can easily damage the mold and, in severe cases, cause the mold to explode. Therefore, the mold must be preheated before use to ensure that the mold reaches a certain temperature when in operation.

[0027] Specifically, through the coordination among structures such as the box 1, control box 2, sensor 3, heater 4, motor 5, frame 6, cylinder 7, card plate 8, plate rack 9, slide 10, placement plate 11, slide plate 12, mesh plate 13, support plate 14, slot 15, support rod 16, spring 17, push plate 18, notch 19, bracket 20, card slot 21, cover plate 22, and observation window 23, multiple metal molds can be heated in a unified manner in the device.

It is merged with the box body 1 through the cover plate 22, and then the heater 4 is turned on through the control box 2 to heat the box body 1. The metal mold can be preheated stably. After the preheating is completed, the cover plate 22 can be opened, and then after the heat in the box body 1 is dissipated, the air The cam 16 is released from the locking cam 14 and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14, and the locking cam 16 is released from the locking cam 14,

[0033] Example 2

[0034] See also Figure 1 、 Figure 5 Based on the first embodiment, the present invention provides a technical solution:

[0035] In this embodiment: a sealing and heat-insulating pad 24 is fixedly connected to the upper surface of the cover plate 22, and a top plate 25 is fixedly connected to the left and right sides of the lower surface of the cover plate 22. A movable groove 26 is provided on the right side of the top plate 25, and a sliding rod 27 is movably installed on the inner surface of the movable groove 26. The outer surface of the sliding rod 27 is movably sleeved with sleeves 28 on the left and right sides. Mounting plates 29 are fixedly installed on the left and right surfaces of the box body 1, and a rotating rod 30 is rotatably provided between the inner wall of the mounting plate 29 close to the center of the box body 1 and the outer wall of the box body 1, and a telescopic cylinder 31 is fixedly installed on the outer surface of the rotating rod 30.

[0036] Specifically, through the cooperation between the sealing insulation pad 24, the top plate 25, the movable groove 26, the slide rod 27, the sleeve 28, the mounting plate 29, the rotating rod 30, the telescopic cylinder 31 and other structures, the cover 22 of the box 1 can be automatically opened and closed, and when the cover 22 is opened, the heat in the box 1 can be dissipated upward, avoiding the harm of heat dissipation to the staff from the front, thereby improving the safety of the working environment.

[0037] In this embodiment, the output end of the telescopic cylinder 31 is fixedly connected to the outer surface of the sleeve 28 on the corresponding side, and the sealing and heat-insulating pad 24 is correspondingly fitted to the front surface of the box body 1 .

[0038] Specifically, the telescopic cylinder 31 performs pushing and pulling operations by cooperating with the sleeve 28 and the slide rod 27 , and can be rotated on the mounting plate 29 by the rotating rod 30 to avoid mutual resistance in movement.

[0039] Working principle: When the metal mold needs to be preheated, after the metal mold is placed in the box body 1, the telescopic cylinders 31 on both sides simultaneously pull the sleeve 28, driving the slide rod 27 to cooperate with the movable groove 26 of the top plate 25 to move to the top, so that the cover plate 22 can be stably close to the surface of the box body 1. The telescopic cylinder 31 exerts force as it pulls, and cooperates with the rotating rod 30 to rotate on the mounting plate 29 to avoid mutual obstruction of movement. Then, after the sealing and insulating pad 24 on the cover plate 22 is fitted with the front surface of the box body 1, the box body 1 can be stably closed. After the preheating work is completed, the telescopic cylinder 31 can push the sleeve 28 to push the slide rod 27, and the slide rod 27 moves to the other side in the movable groove 26 of the top plate 25, which can drive the cover plate 22 to tilt from top to bottom to open the box body 1, and dissipate heat upward.
