Technical Field

[0001] The present application relates to the technical field of extrusion die demoulding, and in particular to a push cleaning device for an extrusion die. Background Art

[0002] The casting extrusion mold mainly includes an upper mold plate, a lower mold plate and a mold core arranged between the upper mold plate and the lower mold plate. A mold cavity is formed in the two mold cores. The product is formed by injecting molten raw materials into the mold cavity. After the product is formed, the slag waste is easy to stick to the mold cavity, affecting its reuse.

[0003] A Chinese patent with publication number CN209491327U discloses a die-casting mold that is convenient for demolding and forming. Two legs are vertically installed at both ends of the lower end of the lower die base, and a push plate is installed between the lower ends of the two legs. A plurality of ejector rods are vertically installed on the push plate. One part of the ejector rods is inserted into the mold cavity, and the other part of the ejector rods passes through the limit block and extends into the connecting groove. Excess waste is ejected by a special ejector rod to ensure the cleanliness of the mold.

[0004] However, in actual use of the above device, the push plate is pushed by hand to move the ejector rod upward. When the waste is firmly bonded, it is difficult to push the push plate and it is quite strenuous. At this time, a hammer is used to hit the push plate to move the push plate upward. However, this method easily damages the push plate and reduces the service life of the device. Summary of the invention

[0006] An embodiment of the present application provides a push cleaning device for an extrusion mold, comprising a base, wherein the base is used to be connected to the bottom of a lower mold base of an extrusion mold, and a driving assembly and a push cleaning assembly are provided on the base. The driving assembly is used to drive the push cleaning assembly to move up and down, so that when the push cleaning assembly moves upward, the slag waste adhered to the mold cavity is ejected, and when the push cleaning assembly moves downward, it can be reset.

[0007] Furthermore, the driving assembly includes a screw, a motor and a tilting moving block, the screw is rotatably mounted on the base, the motor is fixed on the base, one end of the screw is connected to the output shaft of the motor, the tilting moving block is threadedly connected to the screw, and the base is provided with a first guide groove adapted to the tilting moving block, and the first guide groove is slidably connected to the tilting moving block.

[0008] Furthermore, the push cleaning assembly includes a push plate and a plurality of ejector rods, the ejector rods are fixed to the top of the push plate, the bottom of the push plate is connected to the inclined moving block, and the inclined moving block can drive the push plate to move up and down when it moves.

[0009] Furthermore, an inclined slide groove is provided at the bottom of the push plate, the inclined slide groove is adapted to the inclined moving block, and the inclined slide groove is slidably connected to the inclined moving block.

[0010] Furthermore, first guide columns are symmetrically fixed on both sides of the tilting moving block, and a tilting limit groove matched with the guide column is opened on the inner side wall of the tilting slide groove, and the first guide column is slidably connected to the tilting limit groove.

[0027] like Figure 1-3 As shown, the present application provides a push cleaning device for an extrusion mold, including a base 1, which is used to be connected to the bottom of the lower die seat of the extrusion mold. A driving component 2 and a push cleaning component 4 are provided on the base 1. The driving component 2 is used to drive the push cleaning component 4 to move up and down, so that the slag waste adhered to the mold cavity is ejected when the push cleaning component 4 moves upward, and the push cleaning component 4 can be reset when it moves downward. Compared with the prior art, the push cleaning component 4 is driven by the driving component 2 to move up and down, and mechanical power is used instead of manpower to avoid the waste being firmly adhered and the push plate 41 being difficult to push by manpower. There is no need to use a hammer to knock the push plate 41, so the push plate 41 is avoided from being damaged by being knocked, thereby extending the service life of the device.

[0028] like Figure 2 As shown, the driving assembly 2 includes a screw 21, a motor 22 and a tilting moving block 23. The screw 21 is rotatably installed on the base 1, the motor 22 is fixed on the base 1, one end of the screw 21 is connected to the output shaft of the motor 22, the tilting moving block 23 is threadedly connected to the screw 21, and a first guide groove 3 adapted to the tilting moving block 23 is provided on the base 1. The first guide groove 3 is slidably connected to the tilting moving block 23. The screw 21 is driven to rotate by the motor 22, so that the tilting moving block 23 moves on the screw 21.

[0029] like Figure 1 and Figure 2 As shown, the push cleaning assembly 4 includes a push plate 41 and a plurality of ejector rods 42. The ejector rods 42 are fixedly arranged on the top of the push plate 41. The bottom of the push plate 41 is connected to the tilting moving block, and the tilting moving block can drive the push plate 41 to move up and down when it moves. Specifically, when the tilting moving block 23 moves to the left on the screw rod 21, the push plate 41 moves upward, driving the ejector rods 42 to move upward. When the tilting moving block 23 moves to the right on the screw rod 21, the push plate 41 moves downward, driving the ejector rods 42 to reset.

[0030] like Figure 2As shown, an inclined slot 5 is provided at the bottom of the push plate 41, and the inclined slot 5 is adapted to the inclined moving block 23, and the inclined slot 5 is slidably connected to the inclined moving block 23. Through the cooperation between the inclined slot 5 and the inclined moving block 23, when the inclined moving block 23 moves to the left on the screw rod 21, the push plate 41 moves upward, driving the ejector rod 42 to move upward.

[0031] like Figure 2 and Figure 3 As shown, first guide columns 6 are symmetrically fixed on both sides of the tilting moving block 23, and a tilting limit groove 7 matched with the guide column is opened on the inner side wall of the tilting slide groove 5. The first guide column is slidably connected with the tilting limit groove 7. When the tilting moving block 23 moves, the first guide column 6 slides along the tilting limit groove 7. Through the cooperation between the first guide column 6 and the tilting limit groove 7, when the tilting moving block 23 moves to the right on the screw rod 21, the push plate 41 moves downward, driving the ejection rod 42 to reset.

[0032] like Figure 2 As shown, second guide columns 8 are symmetrically fixed on both sides of the push plate 41, and a second guide groove 9 matched with the second guide column 8 is provided on the base 1. The push plate 41 moves up and down along the second guide groove 9 through the second guide column 8. The cooperation between the second guide column 8 and the second guide groove 9 limits the push plate 41, so that the push plate 41 can move up and down stably.

[0033] Working principle:

[0034] The base 1 is connected to the bottom of the lower die seat of the extrusion die, and the ejector rod 42 is inserted into the reserved hole corresponding to the lower die seat of the extrusion die, so that the top of the ejector rod 42 is flush with the bottom of the cavity. When cleaning the slag waste adhering to the cavity, the motor 22 is started, and the motor 22 drives the screw 21 to drive the inclined moving block 23 to move left, so that the push plate 41 moves up, and the push plate 41 drives the ejector rod to move up to eject the excess waste to ensure the cleanliness of the mold. Then the motor 22 drives the screw 21 to drive the inclined moving block 23 to move right, so that the push plate 41 moves down, and the push plate 41 drives the ejector rod to move down and return to the initial position.

[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
