Description

Technical Field

[0001] The utility model relates to a baking box, in particular to a baking box for a lost foam casting hammer head, belonging to the technical field of hammer head production. Background Art

[0002] In the prior art, for example, a utility model with publication number 202220885437.8 discloses a drying device for lost foam casting. In order to evenly dry models of different sizes, during the drying process, the distance between the drying lamp and the model and the position of the drying lamp are adjusted to ensure that the drying lamp is at a suitable distance and irradiates the mold, thereby speeding up the drying of the mold.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The mold is fixed in position during the drying process, and the mold has multiple sides, so the drying lamp cannot evenly irradiate the surface, resulting in uneven baking. In addition, after baking, the oven needs to be completely opened to take out the mold inside, which will cause a large amount of heat loss inside the oven and increase energy loss.

[0005] Therefore, a baking oven for lost foam casting hammer head is designed to optimize the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4As shown, the present embodiment provides a baking oven for lost foam casting hammer head, including a box body 1, drying lamps 2 are evenly arranged on the inner wall of the box body 1, a through opening 3 is arranged at the middle position of the bottom of the box body 1, a transmission box 4 is arranged at the bottom of the box body 1, and the transmission box 4 covers the bottom of the through opening 3, a first motor 5 is installed at the middle position of the bottom of the transmission box 4, a driving gear 6 is installed at the output end of the first motor 5, the driving gear 6 is located at the middle position inside the transmission box 4, the outer side of the driving gear 6 is evenly meshed with a driven gear 7, and the driven gear 7 is rotatably installed inside the transmission box 4, the top of the driven gear 7 is fixed with a support rod 8, the support rod 8 extends to the inside of the box body 1, the top of the support rod 8 is fixed with a lower mesh plate 9, and a clamping mechanism 10 is provided above the lower mesh plate 9 inside the transmission box 4.

[0025] The overall working principle is: after the mold is coated with refractory material, the mold is placed on the top of the lower mesh plate 9, and then the position of the mold is fixed with the clamping mechanism 10, and then the mold is sent into the interior of the box body 1. At this time, the transmission box 4 acts as a box cover to block the opening 3. The box body 1 is sealed, and then the drying lamp 2 is turned on. The drying lamp 2 directly shines on the mold on the side and upper and lower surfaces of the box body 1, and then the first motor 5 is started to control the driving gear 6 to drive the driven gear 7 to rotate. The driven gear 7 controls the mold to rotate at a uniform speed, thereby ensuring that the drying lamp 2 is evenly irradiated on the surface of the mold, and the baking is more uniform and fast.

[0026] In this embodiment, four groups of driven gears 7 are provided, and the angle between adjacent driven gears 7 and the center of the transmission box 4 is 90°.

[0027] Partial working principle: Since there are four groups of driven gears 7, four groups of molds can be dried at the same time during the drying process, and the drying speed is faster.

[0028] In this embodiment, the clamping mechanism 10 includes a vertical rod 20, a mesh plate 21, a second screw 22 and a pressure plate 23. The vertical rod 20 is vertically fixed at the middle position of the top of the transmission box 4. The mesh plate 21 is horizontally fixed to the top of the vertical rod 20. The second screws 22 are evenly arranged on the outside of the mesh plate 21. The second screws 22 are located directly above the center of the lower mesh plate 9, and the second screws 22 are threadedly connected to the mesh plate 21. The bottom of the second screw 22 is rotatably installed with a pressure plate 23.

[0029] Local working principle: After the mold is placed on the top of the lower mesh plate 9, the second screw 22 above the mold is controlled to rotate, and the pressing plate 23 at the bottom of the second screw 22 is in contact with the top of the mold to ensure the stability of the mold. In addition, the pressing plate 23 is rotatably connected to the second screw 22. Therefore, in the process of controlling the rotation of the mold, the mold drives the pressing plate 23 to rotate at the same time, and will not cause wear to the mold.

[0030] In this embodiment, an adjusting block is fixed on the top of the second screw rod 22, and an anti-slip pattern is provided on the outer side of the adjusting block.

[0031] Partial working principle: in the process of controlling the rotation of the second screw rod 22, due to the existence of the adjustment block, manual adjustment can be performed directly, which is more convenient to use.

[0032] In this embodiment, a storage bin 11 is provided at the middle position of the top of the box body 1, a rubber telescopic tube 12 is fixed to the inner top of the storage bin 11, a fixing ring 14 is fixed to the bottom end of the rubber telescopic tube 12, an electric telescopic rod 13 is vertically installed on the outer side of the top of the box body 1, the output end of the electric telescopic rod 13 extends to the interior of the box body 1, the output end of the electric telescopic rod 13 is connected to the fixing ring 14, and a lifting mechanism for controlling the transmission box 4 is provided at the bottom of the box body 1.

[0033] Partial working principle: After baking is completed, the electric telescopic rod 13 is started to drive the fixing ring 14 to move downward. At this time, the rubber telescopic tube 12 is extended. When the fixing ring 14 fits with the inner bottom of the box 1, the outside of the mold is blocked from the inside of the box 1. Then the lifting mechanism is used to control the downward movement and removal of the mold. At this time, a certain amount of heat will be retained inside the box 1 to reduce heat loss, so that other molds can be baked.

[0034] In this embodiment, the lifting mechanism includes a column 15, a ring 16, a connecting rod 17, a second motor 18 and a first screw 19. The column 15 is evenly and vertically fixed at the bottom of the box body 1. The column 15 is provided with a ring 16, and the ring 16 slides along the length direction of the column 15. A connecting rod 17 is installed between the inner side of the ring 16 and the outer side of the first motor 5. The second motor 18 is installed on one side of the bottom of the box body 1, and the first screw 19 is installed at the output end of the second motor 18. The first screw 19 passes through the connecting rod 17 and is threadedly connected to the connecting rod 17.

[0035] Local working principle: During the process of loading and unloading the mold, the second motor 18 is started to drive the first screw 19 to rotate. Since the first screw 19 is threadedly connected to the connecting rod 17, and the connecting rod 17 is fixed on the outside of the first motor 5, the lifting and lowering of the first motor 5 and the transmission box 4 can be controlled to load and unload the mold.

[0036] In this embodiment, a support plate is fixed between the bottom ends of the columns 15, and an anti-slip pad is provided at the bottom of the support plate.

[0037] Partial working principle: When the device is placed, the support plate is in contact with the ground, and the anti-skid pad is used to ensure the stability of the device.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
