Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat treatment equipment for aluminum die-casting products, and more specifically, to an aluminum die-casting heat treatment equipment. Background Technology
[0002] Currently, after aluminum castings are die-cast, they require heat treatment to eliminate internal stress. Common heat treatment devices for aluminum castings include a housing, a lid, and a material rack. One side of the lid is rotatably connected to the upper side of the housing, and the other side is locked to the upper side of the housing via a locking assembly. A handle is fixed to the outer top of the other side of the lid. The material rack is located inside the housing and supports the aluminum castings. An electric heating plate is fixed to the inner wall of the housing. During heat treatment, the aluminum castings are first placed on the material rack, then the rack is hoisted into the housing, and finally the lid is closed. The lid and the box are locked together at the top of the box using a locking assembly. Then, the electric heating plate is energized, and the heat generated by the electric heating plate can heat-treat the aluminum castings located on the material rack. After the aluminum castings are heat-treated, the lid is opened relative to the box, and then the material rack is lifted out of the box by a crane. However, in the above-mentioned aluminum die-casting heat treatment device, when the heat generated by the electric heating plate heats the aluminum castings located on the material rack, due to the principle of hot air rising, the heat used to heat-treat the aluminum castings will be concentrated at the top of the box, that is, the aluminum castings located at the bottom of the box will experience insufficient heat treatment, resulting in poor uniformity of heat treatment of the aluminum castings. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an aluminum die-casting heat treatment device that can improve the uniformity of heat treatment of aluminum castings.
[0004] This utility model provides an aluminum die-casting heat treatment device, including a box body, a box cover, and a material rack; one side of the box cover is rotatably connected to one side of the upper end of the box body, and the other side of the box cover is locked to the other side of the upper end of the box body through a locking assembly, and a handle is fixed on the outer top of the other side of the box cover; the material rack is set inside the box body and is used to support aluminum castings; an electric heating plate is fixed on the inner peripheral wall of the box body; the aluminum die-casting heat treatment device also includes a circulating fan, an exhaust pipe, and a return air pipe; one end of the exhaust pipe passes through one side of the upper end of the box body and communicates with the inner cavity of the box body, the other end of the exhaust pipe is connected to the air inlet of the circulating fan, one end of the return air pipe is connected to the air outlet of the circulating fan, and the other end of the return air pipe passes through the middle of the lower end of the box body and communicates with the inner cavity of the box body.
[0005] By adopting the above structure, during the heat treatment of aluminum castings located on the material rack by the heat generated by the electric heating plate, the circulating fan can draw hot air from the upper part of the box through the exhaust pipe and send the hot air back to the bottom of the box through the return pipe. This allows the hot air in the aluminum die-casting heat treatment device to circulate, which makes the heat in the aluminum die-casting heat treatment device more uniform, thereby improving the uniformity of heat treatment of aluminum castings.
[0006] In one possible implementation, the material rack includes a top plate, a bottom plate, and four circumferentially spaced uprights. Each corner of the bottom plate is fixed with a support block, and the bottom plate is supported by the support blocks on the inner bottom of the housing, leaving a gap between the bottom plate and the inner bottom of the housing. The lower ends of the four uprights are fixed to the bottom plate, and the top plate is fixed to the upper ends of the four uprights. Several partitions are spaced from top to bottom between the top plate and the bottom plate, and the corners of each partition are fixed to the four uprights. These partitions are used to separate the top plate from the bottom plate. The area is divided into several material placement areas for storing aluminum castings, and a pair of lifting rings are fixed to the upper end of the top plate. With this material rack structure, the aluminum castings to be heat treated can be reliably placed in the material placement area, and the material rack can reliably support the aluminum castings. In addition, after the crane hook and the lifting ring are engaged, the material rack can be easily lifted out of the box or into the box, which means that the aluminum castings can be easily lifted out of the box or into the box.
[0007] In one possible implementation, a baffle is provided at each side of the lower end of each material placement area, and both ends of each baffle are welded and fixed to the corresponding column; a channel is formed above each baffle for placing aluminum castings into the material placement area; by providing baffles at each side of the lower end of each material placement area, the baffles can prevent aluminum castings from being lifted out of the material placement area, that is, when the crane lifts the material rack, it can effectively prevent aluminum castings from falling out of the material placement area.
[0008] In one possible implementation, a first cavity is formed inside the bottom edge and the side wall of the box, and the first cavity is filled with a first fireproof and heat-insulating cotton. By adopting this structure, the heat insulation effect of the box can be improved under the action of the first fireproof and heat-insulating cotton, so as to effectively prevent the loss of heat inside the box when the aluminum die-casting heat treatment device heats the aluminum casting.
[0009] In one possible implementation, a second cavity is formed inside the box cover, and the second cavity is filled with a second fireproof and heat-insulating cotton. By adopting this structure, the heat insulation effect of the box cover can be improved under the action of the second fireproof and heat-insulating cotton, thereby effectively preventing the loss of heat inside the box body when the aluminum die-casting heat treatment device heats the aluminum casting.
[0010] In one possible implementation, one side of the lid is rotatably connected to one side of the upper part of the box body via a hinge; with this structure, one side of the lid can be reliably rotatably connected to one side of the upper part of the box body via a hinge.
[0011] In one possible implementation, a sealing ring is embedded at the upper end of the box body to seal the gap between the box cover and the upper end of the box body. With this structure, the sealing effect between the box cover and the box body can be improved after the box cover is closed to the upper end of the box body under the action of the sealing ring. Thus, when the aluminum die-casting heat treatment device heats the aluminum castings, it can effectively prevent the heat inside the box body from being lost through the gap between the box cover and the box body.
