Technical Field

[0001] This invention relates to the field of metal casting, and more specifically to an ultrasonic automatic separator for a casting gating system. Background Technology

[0002] With the advancement of science and technology and industrial production, casting technology has developed extremely rapidly and is widely used in the production of metal buttons and other objects. In the production process of die casting, the die casting machine produces multiple blank products connected as one piece due to the flow channel. There is also excess material on each blank product. Therefore, in order to obtain a single material product, it is necessary to separate the flow channel and the material of the casting blank. The ultrasonic casting separator disclosed in Chinese invention patent CN105665685A has the following problems in actual use: (1) poor use effect. Although some parts are separated from the waste, the separation is not thorough enough. Manual separation is still required later, which increases labor costs; (2) the fallen parts and waste are all mixed together. The parts need to be picked out manually later, which is labor-intensive. Summary of the Invention

[0021] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0022] like Figures 1-6 As shown, an ultrasonic automatic separator for a casting gating system includes a frame 1. The frame 1 is provided with a billet separation mechanism and a product separation mechanism in sequence according to the conveying direction of the casting blank. Each billet separation mechanism and the product separation mechanism is provided with a feeding device 2 below it. Each feeding device 2 is provided with a corresponding conveyor belt device below it.

[0023] Typically, the casting blank 12 includes scrap and product 13. The product is usually surrounded by inner scrap and outer scrap 14. The initial blank separation mechanism can first remove the outer scrap 14, and then transfer the casting blank to the product separation mechanism to separate the product and inner scrap, thereby achieving a clean separation between the product 13 and the scrap, which facilitates the collection and summarization of the product 13 and the scrap.

[0024] The feeding device 2 includes an inclined trough 22. Slider 23 is installed on the two outer side walls of the trough 22. The slider 23 is fixedly connected to the end of a transverse component 24. The transverse component 24 is installed on a frame 1. A slide rod 25 corresponding to the slider 23 is provided on the frame 1. Multiple feeding ports 26 are opened on the trough 22. The feeding ports 26 and the lower output end 22 of the trough 22 correspond to different conveyor belts.

[0025] During operation, the initial blank separation mechanism removes the peripheral waste 14 first, and then the product separation mechanism separates the product. If both peripheral waste and product arrive at the tank 22 at the same time, the lateral movement component 24 controls the lateral movement of the tank 22. Since the outer diameter of the waste is larger than that of the product, the product can fall from the discharge port 26 to the corresponding conveyor belt, while the waste falls from the lower outlet of the tank 22 to the corresponding conveyor belt.

[0026] In this embodiment, the transverse assembly 24 includes a transverse motor 41, a transverse frame 42, a rotating seat 43, a conical block 44, a connecting rod 45, and a transverse rod 46. The transverse frame 42 is mounted on the frame 1. The transverse motor 41 is mounted outside the transverse frame 42. The rotating seat 43 is rotatably mounted inside the transverse frame 42. The output shaft of the transverse motor 41 passes through the transverse frame 42 and is fixed to one end of the rotating seat 43. The conical block 44 is mounted on the rotating seat 43. One end of the conical block 44 is exposed outside the rotating seat 43 and is hinged to the connecting rod 45. The other end of the connecting rod 45 is hinged to the transverse rod 46. The other end of the transverse rod 46 is connected to the slider 23.

[0027] In use, the horizontal movement motor 41 drives the rotating seat 43 to rotate, the rotating seat 43 drives the conical block 44 to rotate, and when the conical block 44 rotates, it drives the horizontal movement rod 46 to reciprocate through the connecting rod 45. The horizontal movement rod 46 drives the slider 23 to move horizontally, thereby driving the trough 22 to reciprocate, so that the product can be shaken off from the discharge port.

[0028] A threaded post 48 is threaded through the rotating seat 43. The two ends of the threaded post 48 are rotatably connected to the rotating seat 43. A nut block 49 is threadedly fitted in the middle of the threaded post 48. The upper and lower end faces of the nut block 49 are rotatably mounted on the conical block 44.

[0029] When it is necessary to increase the lateral movement range of the groove 22, the threaded column 48 is rotated to cause the nut block 49 to shift on the threaded column. The nut block 49 causes one end of the cone block 44 to shift, changing the placement angle of the other end of the cone block 44. This changes the placement angle between the connecting rod 45 and the lateral movement rod 46, thereby increasing the reciprocating movement distance of the lateral movement rod 46 and increasing the vibration range of the groove 22 to adapt to product production.

[0030] The outer end face of the conical block 44 is provided with a mounting hole. One end of the connecting rod 45 is embedded in the mounting hole through a bearing component. The upper and lower end faces of the rotating seat 43 are respectively provided with limit bolts 50. The limit bolts 50 are threadedly connected to the rotating seat 43. The lower end of the limit bolts 50 passes through the rotating seat 43 and the conical block 44 in sequence. The conical block 44 is provided with a through hole for the limit bolts 50 to pass through.

[0031] The connecting rod 45 is arranged in an U-shape, with its upper end located inside the conical block 44, and its lower end hinged to the transverse rod 46.

[0032] The transverse frame 42 is provided with a transverse guide box 47 for the transverse rod 46 to move. The outer end of the transverse rod 46 passes through the transverse guide box 47 and is connected to the slider 23.

[0033] To facilitate the swinging of the rotating seat 43, an opening slot is provided on the rotating seat 43.

[0034] In this embodiment, a screening rod 27 is provided at the bottom of the trough 22. Both ends of the screening rod 27 are respectively installed on the inner sidewall of the trough 22, and a screening trough 28 is formed between the bottom of the screening rod 27 and the bottom surface of the trough 22. Incompletely separated products will contain some waste material. The screening trough 28 can block the products with waste material, making it easier for workers to pick them out and preventing them from falling onto the waste conveyor belt.

[0035] In this embodiment, a material-blocking baffle 32 is provided on the top of the tank 22.

[0036] In this embodiment, the side wall of the slider 23 is provided with a movable groove, and the side wall of the groove 22 extends outward to provide an insert plate. The insert plate is embedded in the movable groove, and the upper and lower end faces of the insert plate and the movable groove form a movable interlayer. An elastic pad is provided at the movable interlayer.

[0037] In this embodiment, the initial billet separation mechanism includes a first separation base 3. Multiple separation handles 20 are respectively provided on both sides of the initial billet separation mechanism. Each separation handle 20 is controlled to rise and fall by its own cylinder. The separation handles press down and bend the peripheral waste material to separate it. The first separation base 3 is installed in the middle of the frame 1. Multiple lower support rods 4 are provided on the first separation base 3. A first separation cylinder is provided directly above the first separation base 3. A first separation plate 5 is installed at the bottom of the first separation cylinder. Upper support rods 6 corresponding to the multiple lower support rods 4 are installed on the first separation plate 5.

[0038] During operation, when the casting blank reaches the station of the initial blank separation mechanism, the first separation plate 5 is lowered by the first separation cylinder. The first separation plate 5 drives the upper support rod 6 to lower, so that the upper support rod 6 can press down the product on the casting blank. Then, the outer waste material 14 of the casting blank is bent and separated by the separation handle.

[0039] In order to prevent the product from being damaged during the initial blank separation mechanism, in this embodiment, an elastic pad 7 is installed on the top of the lower support rod 4, and a spring 8 is installed on the bottom of the upper support rod 6, with an elastic pad installed on the bottom of the spring 8.

[0040] In this embodiment, a compression spring 10 is installed in the middle of the first separating plate 5 to assist in compressing the casting blank.

[0041] In this embodiment, the product separation mechanism includes a second separation base 11, and an ultrasonic separator is disposed directly above the second separation base 11. The ultrasonic separator is installed on the top of the frame 1. Several clamping robots for transferring casting blanks are disposed on the frame. The clamping robots are used to transfer the casting blanks to the corresponding workstations. The ultrasonic separator and the clamping robots are both existing technologies and will not be described in detail here.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments without departing from the technical solution of the present invention, based on the technical essence of the present invention, should be within the scope of the present invention.
