Description

Technical Field

[0001] This utility model relates to the field of heat exchange and heat preservation furnace technology, and to an automatic heat exchange and heat preservation furnace for casting processing. Background Technology

[0002] Automatic heat exchange and holding furnaces used in aluminum alloy casting are key equipment to ensure that aluminum alloy materials maintain an appropriate temperature during the casting process. The structure of the holding furnace usually includes two layers, with a vacuum between the two layers and silver or aluminum plating. The vacuum state can prevent heat convection, and the silver or aluminum plating can reflect the heat energy radiated from the inside back, thereby improving the heat preservation effect.

[0003] The opening of a heat exchange and insulation furnace is usually sealed by a sealing device, which is inserted to seal the furnace. However, when making the finished product, the workers need to scoop out the molten aluminum alloy liquid from the furnace multiple times. The insertion-type sealing device not only increases the complexity of the operation, but may also affect the sealing performance because the sealing device needs to be moved every time the liquid is scooped out.

[0004] To address the aforementioned issues, this application proposes an automatic heat exchange and holding furnace for casting processing. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing an automatic heat exchange and insulation furnace for casting processing.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an automatic heat exchange and heat preservation furnace for casting processing, including a heat preservation furnace body, wherein the opening of the heat preservation furnace body is provided with a sealing structure;

[0007] The sealing structure is provided with an auxiliary structure;

[0008] The sealing structure includes a connector installed at the opening of the heat preservation furnace body. A first arc-shaped block is slidably connected to the inner wall of the connector. A left-hand and right-hand screw is threadedly connected to the inner wall of the first arc-shaped block. A second arc-shaped block is threadedly connected to the outer wall of the left-hand and right-hand screw. The outer wall of the second arc-shaped block is slidably connected to the inner wall of the connector. A motor is provided on the outer wall of the heat preservation furnace body. The output end of the motor is fixedly connected to the outer wall of the left-hand and right-hand screw.

[0009] A sealing block is installed on one side of the first arc-shaped block adjacent to the second arc-shaped block. The outer wall of the sealing block is inserted into the inner wall of the second arc-shaped block. The outer wall of the left and right spiral screw is threaded to the inner wall of the sealing block. By setting the sealing block, the sealing effect of the arc-shaped block is further improved.

[0010] The inner wall of the first arc-shaped block is slidably connected to a sliding column, and the outer wall of the sliding column is slidably connected to the inner wall of the second arc-shaped block. A limit plate is installed on the outer wall of the sliding column. By setting the sliding column, the stability of the arc-shaped block when moving is effectively improved.

[0011] A fixing plate is installed on the outer wall of the heat preservation furnace body. The side of the fixing plate away from the heat preservation furnace body is fixedly connected to the outer wall of the motor. The fixing plate is used to improve the fixing effect of the motor.

[0012] The auxiliary structure includes a slot on the top wall of the connector, into which a support column is inserted. A conical head is installed on the top wall of the support column. By setting the conical head, liquid can be effectively prevented from adhering to the wall of the heat preservation furnace body.

[0013] The inner wall of the conical head is equipped with a limiting component, and the outer wall of the limiting component is fixedly connected to the top wall of the conical head. By setting the limiting component, liquid is further prevented from adhering to the wall of the heat preservation furnace body.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a sealing structure, the starting motor drives the left and right rotating screws to rotate, and the left and right rotating screws drive two arc-shaped blocks to be inserted into each other. Through the repeated rotation of the motor output end, the opening of the heat preservation furnace body is opened and closed, which effectively reduces the complexity of operation and thus effectively improves the sealing performance.

[0016] By setting up an auxiliary device, a conical head is fixed to the connector before the worker scoops out the molten aluminum. When the molten aluminum is scooped out, the conical head can slide the dripping molten aluminum into the interior of the heat preservation furnace, effectively preventing the molten aluminum from adhering.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0028] Reference Figure 1-3An automatic heat exchange and holding furnace for casting processing includes a furnace body 1. A sealing structure 2 is provided at the opening of the furnace body 1. The sealing structure 2 includes a connector 201 installed at the opening of the furnace body 1. The connector 201 is hollow inside and used to house other structures. A first arc-shaped block 202 is slidably connected to the inner wall of the connector 201. A left-hand and right-hand threaded screw 205 is threaded to the inner wall of the first arc-shaped block 202. A second arc-shaped block 203 is threaded to the outer wall of the left-hand and right-hand threaded screw 205. The first arc-shaped block 202 and the second arc-shaped block 203 are symmetrically distributed with different grooves on the left-hand and right-hand threaded screw 205. The outer wall of the second arc-shaped block 203 is slidably connected to the inner wall of the connector 201 and contacts the outer wall of the first arc-shaped block 202. The first arc-shaped block 202 and the second arc-shaped block 203 have the same shape; however, a slot 302 is provided on one side of the second arc-shaped block 203 adjacent to the first arc-shaped block 202.

[0029] A motor 204 is installed on the outer wall of the heat preservation furnace body 1. The output end of the motor 204 is fixedly connected to the outer wall of the left and right rotating screw 205. When the motor 204 is started, the output end of the motor 204 drives the left and right rotating screw 205 to rotate. The left and right rotating screw 205 drives the first arc block 202 and the second arc block 203 to move repeatedly. A sealing block 206 is installed on one side of the first arc block 202 adjacent to the second arc block 203. The outer wall of the sealing block 206 is inserted into the inner wall of the second arc block 203. The outer wall of the left and right rotating screw 205 is threadedly connected to the inner wall of the sealing block 206. When the left and right rotating screw 205 rotates, it drives the first arc block 202, the sealing block 206 and the slot 302 opened in the second arc block 203 to connect, further improving the sealing effect of the heat preservation furnace body 1.

[0030] The inner wall of the first arc-shaped block 202 is slidably connected to a sliding column 207. The outer wall of the sliding column 207 is slidably connected to the inner wall of the second arc-shaped block 203. A limit plate 208 is installed on the outer wall of the sliding column 207. There are two limit plates 208, which are symmetrically distributed at both ends of the sliding column 207 to further improve the stability of the arc-shaped block when it moves.

[0031] A fixing plate 209 is installed on the outer wall of the heat preservation furnace body 1. The side of the fixing plate 209 away from the heat preservation furnace body 1 is fixedly connected to the outer wall of the motor 204. The fixing plate 209 is used to fix the motor 204 to a certain extent, which effectively stabilizes the motor 204 during operation.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An auxiliary structure 3 is provided on the sealing structure 2. The auxiliary structure 3 includes a slot 302 opened on the top wall of the connector 201. A support column 303 is inserted into the slot 302 of the connector 201. A conical head 301 is installed on the top wall of the support column 303. There are six support columns 303, which are distributed at equal intervals around the circumference of the connector 201. The connector 201 also has the same number of slots 302. A limiting member 304 is installed on the inner wall of the conical head 301. The outer wall of the limiting member 304 is fixedly connected to the top wall of the conical head 301. The materials of the conical head 301, slot 302, and support column 303 have the characteristics of high hardness, high wear resistance, high corrosion resistance and high melting point, which can effectively prevent the aluminum liquid from adhering. In addition, when the worker scoops out the aluminum liquid inside the heat preservation furnace body 1, the limiting member 304 can further prevent the aluminum liquid from adhering to the heat preservation furnace body 1.

[0033] Working principle:

[0034] The automatic heat exchange and holding furnace for casting processing starts with motor 204. The output end of motor 204 drives the left and right rotating screw 205 to rotate. The left and right rotating screw 205 drives the first arc block 202, the second arc block 203, and the sealing block 206 to move, so that the first arc block 202 and the second arc block 203 are inserted into each other. The repeated rotation of the output end of motor 204 is used to open and close the opening of the holding furnace body 1, which effectively reduces the complexity of operation and thus effectively improves the sealing performance.

[0035] In the automatic heat exchange and holding furnace for casting, before the worker scoops out the molten aluminum, the support column 303 is aligned with the slot 302 opened in the connector 201, and the conical head 301 is fixed on the connector 201. When the molten aluminum is scooped out, the conical head 301 and the limiting member 304 can make the dripping molten aluminum slide through the conical head 301 into the interior of the holding furnace body 1, effectively preventing the molten aluminum from adhering.
