Description

Technical Field

[0001] The present invention relates to the technical field of die-casting scrap processing, and particularly to a waste recycling device in die-casting machine production. Background Art

[0002] As a core equipment in modern manufacturing, die-casting machines are widely used in fields such as automobiles, electronics, and machinery. Molten metal is injected into molds under high pressure for shaping. However, during die-casting production, a large amount of metal waste is inevitably generated, mainly including the following categories: aluminum waste generated from process waste, defective waste, machining leftovers, and post-casting processing, etc. These wastes can be recycled by collecting, removing impurities, crushing, and then remelting into aluminum blocks.

[0003] During the die-casting process, due to the closing of the moving die and the fixed die, some raw materials will overflow, generating waste such as runners (excess metal overflowing from the mold parting surface) or residues at the gates (the shanks after the pouring system solidifies), etc., mostly in the shape of long strips. For these long-strip die-casting wastes, a double-shaft crusher is usually used in the industry for crushing. However, due to the irregularity of die-castings, the sizes and qualities of the runners overflowing from each corner are different. These wastes of different sizes will collide, stack, and even entangle with each other at the beginning of entering the crusher. First, there will be problems such as difficult crushing and slow crushing speed. Second, the small long-strip wastes will be collided by the larger wastes and accumulate on the other side of the cutter head, which will also affect the normal operation of the cutter head.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-7 , the waste recycling and reuse device in the die-casting machine production of the embodiment of the present invention includes a support component 1 and a linkage feeding and crushing mechanism. Driving components 2 are fixedly installed on both the front and rear sides of the support component 1.

Two material pushing components 4 are fixedly installed on the top of the support component 1, guiding components 5 are fixedly installed on the tops of the two material pushing components 4, and synchronous components 6 are installed on both the front and rear sides of the two guiding components 5.

[0022] The pushing assembly 4 includes a trapezoidal block 41, an L-shaped plate 42 is fixedly installed on the front side of the trapezoidal block 41, an eccentric wheel 43 is inserted in the parallel direction of the L-shaped plate 42, a rotating wheel 44 is installed on the outer edge of the eccentric wheel 43, and a push rod 45 is movably hinged on the rotating axis of the rotating wheel 44. The outer edge of the push rod 45 is sleeved with a third spring 46, the push rod 45 is inserted in the vertical direction of the L-shaped plate 42, and the movable end of the push rod 45 is fixedly connected to the push plate 47; the push rod 45 is composed of a round block and a round rod, the bottom end of the third spring 46 is elastically connected to the top of the round block, and the top of the third spring 46 is fixedly connected to the L-shaped plate 42, and a second motor 48 is fixedly connected between the two eccentric wheels 43, and the second motor 48 is fixedly installed on the side of the trapezoidal block 41.

[0023] The second motor 48 is started and driven clockwise, causing the eccentric wheel 43 connected thereto to rotate eccentrically, and the rotating wheel 44 sleeved on the outside of the eccentric wheel 43 can perform cyclic speed-changing circular axis motion. When this is reflected on the push rod 45, the push rod 45 will drive the push plate 47 to perform a reciprocating speed-changing pushing action under the elastic action of the third spring 46, thereby performing a sudden push on the waste material, so that the waste material can be as close to the reamer 38 as possible, solving the problem that small and long waste strips are collided with larger waste and accumulated on the other side of the reamer 38, which will also affect the normal operation of the reamer 38.

[0024] The support assembly 1 includes multiple support seats 11, two arc blocks 12 are fixedly installed on the top of the multiple support seats 11, two baffles 13 are inserted on the top of the two arc blocks 12, and rubber rings 14 are installed in the middle of the two baffles 13.

[0025] The arc block 12 and the baffle 13 can form a cavity required for the crushing work and start supporting the other equipment. The rubber ring 14 can ensure the rotation and displacement of the rotating shaft of the reamer 38 and prevent the waste from interfering with the rotating shaft of the reamer 38.

[0026] Among them, the driving component 2 includes two symmetrically installed movable mechanisms, which include a disc 21, which is fixedly installed on the front side of the arc block 12. A coil spring 22 is elastically connected inside the disc 21, and a U-shaped rod 23 is fixedly connected to the middle position of the coil spring 22. The other end of the U-shaped rod 23 is fixedly connected to a C-shaped metal spring 24, and a U-shaped spring 25 is fixedly connected to the inside of the other side of the C-shaped metal spring 24.

[0027] Start two first motors 26 to rotate in opposite directions respectively, driving two reamers 38 to rotate relatively. When adjusting the crushing diameter or when the reamer 38 is displaced by gravity, the first motor 26 can elastically deform within the disc 21 through the C-shaped metal elastic piece 24 with the help of the spiral spring 22 to obtain displacement allowance, so that the first motor 26 can always provide driving force for the displaced reamer 38.

[0028] Among them, the crushing assembly 3 includes an outer ring 31, the outer ring 31 is fixedly installed on the tops of two arc-shaped blocks 12, a wave ring 32 is elastically connected to the inner side of the outer ring 31, an inner ring 33 is elastically connected to the inner side of the wave ring 32, grooves 34 are respectively formed in the upper and lower parts of the inner side of the inner ring 33, two movable pieces 35 are movably clamped in the grooves 34, two bidirectional hydraulic rods 36 are fixedly connected between the two movable pieces 35, connecting blocks 37 are installed at the fixed ends of the two bidirectional hydraulic rods 36, and reamers 38 are rotatably installed inside the two movable pieces 35; the other ends of the two connecting blocks 37 are fixedly connected to the front end of the inner ring 33, the rotating shafts of the two reamers 38 are fixedly connected to the output shafts of the first motors 26, and the two reamers 38 are symmetrically installed.

[0029] During the feeding process, the two rotating reamers 38 will be subjected to the weight of the waste and displace downward. At this time, the two reamers 38 will press the wave ring 32 on the inner side of the outer ring 31 through the inner ring 33 connected by the movable pieces 35, causing the wave ring 32 to deform, so as to reduce the hard impact on the reamer 38, thereby protecting the mechanical structure and increasing the service life of the equipment.

[0030] Among them, the guiding assembly 5 includes a fixed rod 51, the fixed rod 51 is fixedly installed on the top inclined surface of the trapezoidal block 41, a torsion spring 52 is sleeved on the edge of the fixed rod 51, a feeding plate 53 is movably hinged to the outer edge of the fixed rod 51, the middle part of the torsion spring 52 is fixedly connected to the outer edge of the fixed rod 51, and both ends of the torsion spring 52 are inserted into the feeding plate 53. The synchronization assembly 6 includes a first rack 61, the first rack 61 is movably hinged to the front side of the right feeding plate 53, a limit block 62 is sleeved on the outer edge of the first rack 61, a gear 63 is engaged with the bottom side of the first rack 61, and a second rack 64 is engaged with the bottom side of the gear 63; the limit block 62 is fixedly installed at the bottom of the baffle 13, the first rack 61 and the second rack 64 are symmetrically installed, the bottom of the second rack 64 is slidably installed on the top of the baffle 13, the other end of the second rack 64 is movably hinged to the front side of the left feeding plate 53, and a bent rod is inserted into the gear 63, and the bottom of the bent rod is fixedly connected to the top side of the outer ring 31.

[0031] When feeding, the feed plate 53 on one side can be pressed. After the force is applied, the feed plate 53 will rotate around the fixed rod 51 and elastically rotate the torsion spring 52. At the same time, the first rack 61 will also be pulled by the displaced feed plate 53. After the gear 63 is rotated, the displacement force can be transmitted in the opposite direction to the second rack 64. At this time, the second rack 64 will push the feed plate 53 on the other side to undergo the same twisting. Then, the two symmetrical feed plates 53 present a trapezoidal channel with a gradually larger top opening and a gradually smaller bottom opening, thereby reducing the problem of waste being too dispersed when entering the reamer 38.

[0032] Working principle: When using the present invention, first start the two first motors 26 to rotate in opposite directions, driving the two reamers 38 to rotate relative to each other, and then put the collected die-casting waste of different sizes and qualities into the cavity formed by the arc block 12 and the baffle 13.

[0033] When feeding, the feed plate 53 on one side can be pressed. After the force is applied, the feed plate 53 will rotate around the fixed rod 51 and elastically rotate the torsion spring 52. At the same time, the first rack 61 will also be pulled by the displaced feed plate 53. After the gear 63 is rotated, the displacement force can be transmitted in the opposite direction to the second rack 64. At this time, the second rack 64 will push the feed plate 53 on the other side to undergo the same twisting. Then, the two symmetrical feed plates 53 present a trapezoidal channel with a gradually larger top opening and a gradually smaller bottom opening, thereby reducing the problem of waste being too dispersed when entering the reamer 38.

[0034] During the feeding process, the two rotating reamers 38 will be affected by the weight of the waste and move downward. At this time, the two reamers 38 will press the wave ring 32 inside the outer ring 31 through the inner ring 33 connected by the movable piece 35, causing the wave ring 32 to deform, thereby reducing the hard impact on the reamers 38, thereby protecting the mechanical structure and increasing the service life of the equipment.

[0035] When the reamer 38 crushes the long waste, the farther away from the reamer 38 the arc block 12 and the baffle 13 are from the longitudinal space of the cavity, the less likely the waste will be captured and crushed. At this time, the second motor 48 is started and driven clockwise, causing the eccentric wheel 43 connected thereto to rotate eccentrically, and the runner 44 sleeved on the outer side of the eccentric wheel 43 can perform a circular shaft motion with a cyclic speed change. When this is reflected on the push rod 45, the push rod 45 will drive the push plate 47 to perform a reciprocating speed change pushing action under the elastic action of the third spring 46, thereby pushing the waste forward so that the waste can be as close to the reamer 38 as possible.

[0036] When the two-way hydraulic rod 36 contracts, the two movable pieces 35 will slide and approach in the groove 34, thereby shortening the distance between the two reamers 38, realizing the adjustment of the crushing diameter of the waste material by the equipment. When adjusting the crushing diameter or when the reamer 38 is displaced by gravity, the first motor 26 can elastically deform in the disc 21 through the C-shaped metal elastic piece 24 with the help of the spiral spring 22 to obtain displacement allowance, so that the first motor 26 can always provide driving force for the displaced reamer 38.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
