The mold needs to be preheated before the casting process so that the cast mechanical parts have better quality.

[0003] When heating the existing mold, the mold needs to be placed in a heating device for heating, and then the mold is taken out for pouring. Moving the mold back and forth causes great inconvenience, and it is easy to collide and damage the pouring mold. In addition, placing the mold at the bottom of the preheating box for heating will make it difficult for the bottom of the mold to heat quickly, thereby reducing the overall preheating efficiency of the mold.

[0004] For this reason, we propose a mold preheating device. Utility Model Content

[0026] Specifically, through the cooperation among structures such as the workbench 1, the preheating box 2, the control panel 3, the feed port 4, the first heater 5, the second heater 6, the slide 7, the mold frame 8, the first cylinder 9, the push plate 10, the card slot 11, the mold body 12, the support plate 13, and the second cylinder 14, the mold can be automatically sent to the preheating box 2 for preheating, saving the time of manual picking and placing back and forth, and the mold can be propped up. By partially supporting the bottom of the mold, the mold located in the center of the preheating box 2 can be fully heated, thereby improving the preheating efficiency of the mold.

[0027] In this embodiment, the control panel 3 is electrically connected to the first heater 5 and the second heater 6 , and the first cylinder 9 and the slide groove 7 are arranged to slide correspondingly.

[0028] Specifically, the control panel 3 and the first heater 5 and the second heater 6 are existing structures, and the control circuit can be implemented through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection are not described in detail. The cylinder can move in the slide groove 7 as the mold frame 8 moves, thereby avoiding mutual obstruction between the first cylinder 9 and the workbench 1.

[0029] In this embodiment, the push plate 10 is arranged corresponding to the card slot 11, the push plate 10 is attached to the bottom of the mold body 12, and the output end of the second cylinder 14 is fixedly connected to the right surface of the support plate 13 on the corresponding side.

[0030] Specifically, the mold frame 8 can be transported and moved horizontally by the cooperation of the second cylinders 14 on both sides and the support plates 13 .

[0031] Working principle: When it is necessary to preheat the mold for casting, the workbench 1 is located in the designated working area, the mold body 12 is placed in the mold frame 8, and then the second cylinders 14 on both sides are turned on to pull the support plate 13 to drive the mold frame 8 to move horizontally to the right. The mold frame 8 drives the first cylinder 9 at the bottom to move horizontally through the slide 7 on the workbench 1, and enters the preheating box 2 through the feed port 4, and then adjusts the effects of the first heater 5 and the second heater 6 through the control panel 3, and then turns on the first cylinder 9 to drive the push plate 10 to move upward. At the same time, the push plate 10 passes through the card slot 11 on the mold frame 8, and then the push plate 10 fits the mold body 1 2, the mold is propped up by the push plate 10 and positioned at the center of the preheating box 2, and then the first heater 5 and the second heater 6 cooperate to heat the mold body 12, so that the mold body 12 is quickly heated. Since the bottom force-bearing area of ​​the mold body 12 is small, it can efficiently absorb heat to complete the preheating work. After the mold preheating is completed, the first cylinder 9 drives the push plate 10 to descend through the card slot 11 to reset, thereby driving the mold body 12 to move to the mold frame 8 to reset, and then the second cylinders 14 on both sides are opened to cooperate with the support plate 13 to push the mold frame 8 to the left and extend it out of the feed port 4, so that the preheated mold body 12 can be taken out for use using tools.

[0032] Embodiment 2

[0033] Please refer to the figure. Based on the first embodiment, the utility model provides a technical solution:

[0034] In this embodiment: a fixing frame 15 is fixedly installed on the left surface of the preheating box 2, a rotating rod 16 is rotatably arranged between the front and rear inner walls of the fixing frame 15, a cover plate 17 is fixedly connected to the outer surface of the rotating rod 16, a heat insulating rubber ring 18 is fixedly connected to the lower surface of the cover plate 17, and a reduction motor is fixedly installed on the rear surface of the fixing frame 15.

[0035] Specifically, the inlet and outlet of the preheating box 2 can be closed by the cooperation among the second cylinder 14, the fixing frame 15, the rotating rod 16, the cover plate 17, the heat insulating rubber ring 18, the reduction motor 19 and other structures. Since most of the heat will accumulate at the top of the preheating box 2, the heat dissipation of the preheating box 2 is reduced, thereby making full use of the heat.

[0036] In this embodiment, the output end of the motor is fixedly connected to the rear surface of the rotating rod 16 , and the cover plate 17 is correspondingly adapted to the feed port 4 .

[0037] Specifically, the motor drives the rotating rod 16 to rotate forward and reverse, thereby controlling the cover plate 17 and the feed port 4 to close and open.

[0038] Working principle: When the mold is heated by the preheating box 2, the mold frame 8 and the mold body 12 enter the preheating box 2 together, and the reduction motor 19 on the fixed frame 15 is turned on to drive the rotating rod 16 to reverse, and the rotating rod 16 drives the cover plate 17 to reverse, so that the cover plate 17 drives the thermal insulation rubber ring 18 to fit the edge of the feed port 4, and then the reduction motor 19 is turned off. The feed port 4 can be shielded by the cover plate 17 and the thermal insulation rubber ring 18 to prevent a large amount of heat from dissipating from the feed port 4 and reduce the volatilization of heat, thereby ensuring that the mold in the preheating box 2 can make full use of the heat. When the mold body 12 needs to be taken out after preheating, the reduction motor 19 is turned on to drive the rotating rod 16 to rotate forward, and the rotating rod 16 drives the cover plate 17 to separate the thermal insulation rubber ring 18 from the edge of the feed port 4 and reverse upward, and then the reduction motor 19 is turned off, and the mold body 12 can be transported out of the feed port 4.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
