Description

Technical Field

[0001] The utility model relates to the technical field of production of precision aluminum alloy die castings, in particular to a rapid demoulding device for precision aluminum alloy die castings. Background Art

[0002] Precision aluminum alloy die castings are a type of pressure-cast parts. They are made by using a pressure casting mechanical die-casting machine equipped with a casting mold. The aluminum alloy and other metals heated to liquid form are poured into the inlet of the die-casting machine. The die-casting machine then die-casts the aluminum alloy parts in the shape and size limited by the mold.

[0003] When demolding is performed after the die-casting process of existing aluminum alloy die-castings is completed, part of the raw materials will adhere to the inner wall of the fixed mold, which is not easy to peel off and demold, and easily affects the subsequent die-casting processing. The current conventional operation is: the user holds a high-pressure flushing spray rod to flush the two halves of the mold after the mold is opened to achieve the effect of removing the adhered raw materials. The operation is time-consuming and laborious, and due to the high temperature of the fixed mold during aluminum alloy die-casting, there is also the possibility of scalding the operator.

[0004] Therefore, we propose a rapid demoulding device for precision aluminum alloy die castings to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a rapid demoulding device for precision aluminum alloy die castings to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A precise aluminum alloy die-casting rapid demoulding device comprises a frame, a water tank and a punching structure, wherein the water tank is mounted on the frame and is connected to the inside of the punching structure through a high-pressure water pump and a soft water pipe, and the punching structure is mounted on one side of the frame through an L-shaped hanging plate, and the punching structure is hoisted on the die-casting fixed die and moves up and down relative to the die-casting die;

[0008] The punching structure includes a hard water pipe, a horizontal pipe connected to the bottom end of the hard water pipe, branch pipes spaced evenly along the length of the horizontal pipe, and a liquid nozzle installed at the water outlet of each branch pipe;

[0009] A square sleeve is fixedly connected to the outer surface of the hard water pipe, and the square sleeve passes through the L-shaped hanging plate. A servo motor is installed on the L-shaped hanging plate. A main gear is connected to the output shaft of the servo motor, and the main gear is meshed with the teeth on the side wall of the square sleeve. When the main gear rotates, the lifting and lowering movement of the punching structure is controlled.

[0010] In a further embodiment, the branch pipes are symmetrically distributed on the left and right sides of the transverse pipe, and the branch pipes on both sides are inclined downward relative to the transverse pipe to form an "eight"-shaped structure.

[0011] In a further embodiment, the spray width of the liquid nozzle is greater than half of the distance between two adjacent liquid nozzles.

[0012] In a further embodiment, a hard air pipe is passed through the interior of the square sleeve, the bottom end of the hard air pipe is connected to a gas nozzle, and the top end of the hard air pipe is connected to a high-pressure blower through a soft air pipe.

[0013] In a further embodiment, the gas nozzle adopts a duckbill structure, and the length of the air outlet of the gas nozzle is greater than the length of the cross pipe.

[0014] In a further embodiment, the left and right side walls of the square sleeve are connected with straight rails, and a roller is rotatably connected to the inner wall of the slot hole through which the square sleeve passes on the L-shaped hanging plate, and the roller fits tightly with the straight rails.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model is arranged that after the fixed mold is opened and the die-casting is removed, the square sleeve is controlled to descend by rotating the main gear, and after the hard water pipe in the flushing structure is connected to the water source in the water tank, a linear jet flushing water flow can be formed through the horizontal pipe, the branch pipe and the liquid nozzle output, so that the templates on both sides can be flushed while the square sleeve descends, and the residual raw materials adhering to the templates can be effectively removed, thereby improving the demoulding efficiency.

[0017] After the utility model arranges the hard air pipe to connect the output airflow of the soft air pipe and the high-pressure blower, a linear airflow can be formed through the hard air pipe and the gas nozzle during the descending process of the square sleeve, so that after the liquid is flushed and demolded, another gas flushing is performed to blow away the residual water droplets on the template, so that the fixed mold can be put into normal use next time more quickly.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-3The rapid demoulding device for precision aluminum alloy die castings comprises a frame 1, on which a water tank 2 is mounted. In order to facilitate water replenishment of the water tank 2, a cover is fixed on the water tank 2 by screws so that it can be opened. A punching structure is mounted on one side of the frame 1 close to the die-casting fixed mold through an L-shaped hanging plate 9. The punching structure is hoisted above the die-casting fixed mold. The punching structure is lifted up and down relative to the L-shaped hanging plate 9 to facilitate approaching or moving away from the die-casting fixed mold. A high-pressure water pump 8 is mounted on the cover of the water tank 2. The water inlet end of the high-pressure water pump 8 extends into the water tank 2 through a pipeline, and the water outlet end of the high-pressure water pump 8 is connected to a soft water pipe 7 The punching structure includes a hard water pipe 3, a transverse pipe 4 connected to the bottom end of the hard water pipe 3, branch pipes 5 equidistantly distributed along the length direction of the transverse pipe 4, and a liquid nozzle 51 installed at the water outlet of each branch pipe 5. The transverse pipe 4, the branch pipe 5 and the liquid nozzle 51 are internally connected, and the top of the hard water pipe 3 is connected to the soft water pipe 7 through a pipe joint to make the insides thereof communicate, so that when the high-pressure water pump 8 is started, water can be supplied to the transverse pipe 4, the branch pipe 5 and the liquid nozzle 51, so that the water flow sprayed from the liquid nozzle 51 can flush the surface of the template, so as to facilitate the stripping and demoulding of the residual raw materials.

[0027] See also Figure 2-3 In order to improve the flushing effect, the branch pipes 5 are symmetrically distributed on the left and right sides of the horizontal pipe 4, and the branch pipes 5 on both sides are inclined downward relative to the horizontal pipe 4 to form an "eight"-shaped structure. The branch pipes 5 are inclined so that when flushing, the flushing water flow forms an acute angle with the upper surface of the template, which can maintain the effect of flushing the debris on the template downward, thereby facilitating the flushing of the debris and reducing the possibility of the debris splashing upward. In addition, the spray width of the liquid nozzle 51 is set to be greater than half of the distance between two adjacent liquid nozzles 51, so that the water flows flushed out between the adjacent liquid nozzles 51 are staggered, thereby preventing the linear water flow formed by a row of liquid nozzles 51 from being disconnected in the middle, thereby ensuring the integrity of the flushing surface.

[0028] See also Figure 1-3 Considering that when the die-casting fixed mold is closed, the punching structure needs to be raised to prevent it from occupying the position between the templates, and when the mold is opened, the punching structure needs to be lowered to fully flush the template surface. In order to facilitate the lifting and moving of the punching structure, a square sleeve 6 is fixed to the outer shell of the hard water pipe 3. The square sleeve 6 wraps the hard water pipe 3, and the square sleeve 6 passes through the slot on the L-shaped hanging plate 9. The rear side wall of the square sleeve 6 is evenly provided with teeth 61, and the teeth 61 are equidistantly distributed in the vertical direction. A servo motor 10 is installed on the L-shaped hanging plate 9. The output shaft of the servo motor 10 is connected to a main gear 11 through a coupling. The main gear 11 is rotatably installed relative to the L-shaped hanging plate 9, and the main gear 11 is meshed with the teeth 61, so that when the main gear 11 rotates, the meshing action is used to drive the square sleeve 6 to move up and down, thereby controlling the lifting and moving of the punching structure.

[0029] See also Figure 4 In order to further improve the stability of the square sleeve 6 when it is lifted or lowered, straight rails 62 are connected to the left and right side walls of the square sleeve 6, and a roller 91 is rotatably connected to the inner wall of the slot through which the square sleeve 6 passes on the L-shaped hanging plate 9. The roller 91 fits tightly with the straight rail 62, the middle part of the roller 91 protrudes outward, and the middle part of the straight rail 62 is recessed inward, so that they match each other. The roller 91 and the straight rail 62 are used to limit the square sleeve 6, thereby reducing its shaking during work.

[0030] See also Figure 2-3 Considering that water droplets are likely to remain on the surface of the template after flushing with water, which will affect the next die-casting operation, in order to quickly remove these water droplets, a hard air pipe 12 is arranged inside the square sleeve 6, and the bottom end of the hard air pipe 12 is connected to the gas nozzle 13, and a high-pressure fan 15 is fixed on the box cover of the water tank 2, and the air outlet end of the high-pressure fan 15 is connected to the soft air pipe 14, and the other end of the soft air pipe 14 is connected to the hard air pipe 12 through a pipe joint, so that when the high-pressure fan 15 is working, the soft air pipe 14, the hard air pipe 12 and the gas nozzle 13 are connected, so that the gas nozzle 13 sprays gas to blow away the water droplets.

[0031] See also Figure 2-3 Furthermore, in order to improve the efficiency of removing water droplets, the gas nozzle 13 is set to adopt a duckbill structure, and the length of the air outlet of the gas nozzle 13 is greater than the length of the horizontal tube 4, and the air outlet of the gas nozzle 13 is also inclined downward like the branch pipe 5, so that the air outlet of the gas nozzle 13 is a linear air outlet, with a wider effective surface and higher efficiency.
