Description

Technical Field

[0001] The utility model relates to the technical field of aluminum die-casting of casings, in particular to an aluminum die-casting mechanism for casings. Background Art

[0002] Since the structure of the pump casing is relatively complex, die-casting is often used for the convenience of processing. During the processing, at least two mold cavities that can be assembled together are included. The aluminum liquid is delivered to the mold cavity through the pouring port, and then the pump casing is waited for to be formed. Then, the coolant and the mold release agent are sprayed to make it quickly cooled and demolded, thereby realizing the die-casting of the rough blank of the pump casing. Before the aluminum liquid enters the mold cavity, the aluminum liquid is first placed in an insulation tube for storing the aluminum liquid, and then pressure is applied to press the aluminum liquid in the insulation tube into the mold cavity. Since the existing insulation tube has only one, its length is relatively long, and a cylinder is also required to push the aluminum liquid in the insulation tube, resulting in a longer overall molding mechanism and more space occupation.

DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a casing aluminum die-casting molding mechanism includes a base 1, a fixed mold 2 is arranged on the base 1, a fixed plate 3 is arranged on one side of the base 1, a guide rod 4 is arranged between the base 1 and the fixed plate 3, a movable mold 5 is slidably connected to the guide rod 4, a first cylinder 6 is arranged on one side of the fixed plate 3, and the output end of the first cylinder 6 is fixedly connected to the movable mold 5, an insulation pipe 7 is symmetrically arranged on one side of the fixed mold 2, the insulation pipe 7 is through-connected with the inner cavity of the fixed mold 2, a through hole is opened on the upper surface of the insulation pipe 7, a guide hopper 8 is arranged on the upper surface of the insulation pipe 7, and the guide hopper 8 is through-connected with the insulation pipe 7 through the through hole, a slider 9 is slidably connected inside the insulation pipe 7, a push rod 10 is arranged at one end of the slider 9, and the two push rods 10 are connected by a cross plate 11, a second cylinder 12 is arranged on one side of the fixed mold 2, and the output end of the second cylinder 12 is fixedly connected to the cross plate 11.

[0017] When die-casting the casing, first, the first cylinder 6 on one side of the fixed plate 3 is started by controlling the first cylinder 6 to extend and push the movable mold 5 to move along the guide rod 4 and the base 1. When the fixed mold 2 and the movable mold 5 are closed, a die-casting chamber of the casing is formed between the fixed mold 2 and the movable mold 5. Then, the aluminum liquid is taken through the external pipetting trough. The pipetting trough has two V-shaped discharge troughs to facilitate the simultaneous injection of aluminum liquid into the two guide hoppers 8. The aluminum liquid enters the insulation tube 7 through the guide hopper 8. Then, the second cylinder 12 is controlled to start, and the output end of the second cylinder 12 retracts to drive the push rod 10 to move. The push rod 10 pushes the slider 9 to move in the insulation tube 7. During the movement of the slider 9, it can quickly close the through hole of the insulation tube 7 by itself to prevent the aluminum liquid in the insulation tube 7 from flowing back into the guide hopper 8. During the movement of the slider 9, all the aluminum liquid in the insulation tube 7 is pushed into the die-casting chamber, and the air in the die-casting chamber is discharged through the exhaust holes on the fixed mold 2 and the movable mold 5.

[0018] Furthermore, a groove is provided on the base 1, and a lead screw 13 is rotatably connected inside the groove. A motor 14 for driving the lead screw 13 to rotate is provided on one side of the base 1, and a moving block 15 is slidably connected inside the groove. The moving block 15 is threadedly connected to the lead screw 13, and a liquid storage chamber 16 is provided on the upper end surface of the moving block 15. Sprinkler heads 17 are evenly provided on both sides of the outer surface of the liquid storage chamber 16, and a delivery pipe 18 is provided on the outer surface of the liquid storage chamber 16. When the formed casing needs to be quickly cooled, the delivery pipe 18 is connected to an external high-pressure water pump, and then the motor 14 is started. The motor 14 drives the lead screw 13 to rotate. Since the moving block 15 can It moves in the groove, and the lead screw 13 is threadedly connected to the moving block 15, so that the moving block 15 can make a linear motion along the lead screw 13 in the groove, and move the liquid storage chamber 16 to between the fixed mold 2 and the movable mold 5, and then turn on the high-pressure water pump. After the high-pressure water pump is turned on, the cooling water is transported to the liquid storage chamber 16 through the delivery pipe 18, and sprayed to the outer surface of the casing through the spray head 17 outside the liquid storage chamber 16, so as to achieve rapid cooling of the casing. At the same time, the demoulding agent can also be mixed in the coolant to facilitate the demoulding of the casing. After the demoulding of the casing is completed, the liquid storage chamber 16 is moved out from between the fixed mold 2 and the movable mold 5 by controlling the motor 14 to reverse.

[0019] Furthermore, the insulation tube 7 and the second cylinder 12 are both inclined, and the inclination angle and direction of the insulation tube 7 and the second cylinder 12 are the same. The horizontal height of the insulation tube 7 close to one end of the fixed mold 2 is lower than the horizontal height of the other end of the insulation tube 7. The insulation tube 7 is inclined so that the aluminum liquid entering the insulation tube 7 can flow toward the lower position of the insulation tube 7. When a large volume of aluminum liquid is required, more aluminum liquid can be added to the insulation tube 7, and a large amount of aluminum liquid can be kept away from the through hole on the insulation tube 7, so as to prevent the aluminum liquid from overflowing from the through hole when the slider 9 moves.

[0020] Furthermore, the lower end of the insulation tube 7 is connected to the bottom of the inner cavity of the fixed mold 2. After the aluminum liquid enters the die-casting chamber, the slider 9 squeezes the aluminum liquid in the insulation tube 7, and the aluminum liquid can gradually move upward from the bottom of the die-casting chamber, thereby improving the stability of the flow of the aluminum liquid in the die-casting chamber.

[0021] Furthermore, two first cylinders 6 are provided and symmetrically arranged on one side of the fixed plate 3 to improve the stability of the movement of the movable mold 5 .

[0022] When the device is in use, two insulation tubes 7 are set to replace one insulation tube 7, so that the length of the insulation tube 7 can be significantly shortened while accommodating the same volume of aluminum liquid and keeping the diameter of the insulation tube 7 unchanged, thereby reducing the space occupied, shortening the stroke of the slider 9, and improving production efficiency. Moreover, when the second cylinder 12 is working, since the insulation tubes 7 on both sides thereof are symmetrically arranged, the output end of the second cylinder 12 and the push rod 10 have high stability when moving.

[0023] In the description of the present invention, 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 an indirect connection 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 invention can be understood according to specific circumstances.
