Description

Technical Field

[0001] The present invention relates to the technical field of die-casting mechanisms, in particular to a multi-slide high-precision and high-speed die-casting machine. Background Art

[0002] The die-casting process uses high pressure and high speed to force molten metal into the cavity of a precision metal mold. Under pressure, the molten metal cools and solidifies, forming a casting. Cold- and hot-chamber die-casting are the two basic methods of die-casting. In cold-chamber die-casting, molten metal is poured into the chamber manually or automatically. Then, a shot punch advances, forcing the metal into the cavity. In hot-chamber die-casting, the chamber is perpendicular to the crucible, and molten metal flows automatically into the chamber through a feed port on the chamber. The shot punch moves downward, pushing the molten metal through a gooseneck tube into the cavity. After the molten metal solidifies, the die-casting mold is opened and the casting is removed, completing the die-casting cycle. Due to the high precision of die-casting parts, they require only minimal machining before assembly and use, and some die-casting parts can be assembled directly, resulting in high production efficiency. Due to the high-speed filling, short filling time, rapid metal solidification, fast die-casting cycle speed, and convenient use of inlays; die-casting has high production efficiency and can die-cast parts with complex shapes, precise dimensions, clear contours, high surface quality, high strength, and hardness. Therefore, it is widely used and has developed rapidly. At present, the output of aluminum alloy die-casting parts is the largest, followed by zinc alloy die-casting parts. However, the existing die-casting has the following major problems: before die-casting, the feed port of the die-casting machine is exposed to the air. Dust or other impurities in the air splash into the feed port and are difficult to remove. As a result, when the liquid material is poured into the feed port later, impurities enter the liquid material and are die-cast into shape, resulting in quality problems after die-casting.

[0006] Furthermore, the four sliders are each provided with a bevel one and a bevel two, the four sliders are arranged in a rectangular shape, and bevel one abuts against bevel two between two adjacent sliders. The mold assembly includes: a fixed mold and a movable mold, the fixed mold is fixedly connected to the upper end of the base, and the movable mold is fixedly connected to the slider.

[0008] Furthermore, the feed port covering assembly includes: a right-angle block, which is slidably arranged in the operating port, one end of the right-angle block is slidably connected in the rectangular cavity, both sides of one end of the right-angle block are fixedly connected to one end of spring one, and the other end of spring one is fixedly connected to the bottom of the operating port, an inclined groove is provided on the upper surface of the right-angle block, a socket is provided on one side of the fixed mold, the position of the socket corresponds to the position of one end of the inclined groove, the movable mold is fixedly connected to one end of the plug block, the plug block corresponds to the position of the socket, and a protrusion is fixedly connected to the lower surface of one end of the plug block.

[0009] Furthermore, the limiting assembly includes: a rack, the rack is fixedly connected to one side of the movable mold, a rotating shaft is rotatably connected to the base, one end of the rotating shaft is fixedly connected to a gear, the other end of the rotating shaft is fixedly connected to one end of a connecting rod, the other end of the connecting rod is rotatably connected to a roller, a limiting hole is provided on the connecting rod, a limiting rod is slidably connected to the base, the lower end of the limiting rod is fixedly connected to one end of spring two, the other end of spring two is fixedly connected to the base, and the upper end of the limiting rod is hemispherical.

[0010] Furthermore, both sides of the movable mold are slidably connected with push rods, a spring three is sleeved on the push rods, and a baffle is fixedly connected to the base.

[0011] Furthermore, the pushing assembly includes: a second cylinder, which is fixedly connected to the base, an output end of the second cylinder is fixedly connected to one end of a push rod, and the other end of the push rod is slidably connected to the pushing port.

[0012] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects: 1. Since the right-angle block is slidably arranged in the operation port, one end of the right-angle block is slidably connected to the rectangular cavity, both sides of one end of the right-angle block are fixedly connected to one end of the spring 1, and the other end of the spring 1 is fixedly connected to the bottom of the operation port. An inclined groove is provided on the upper surface of the right-angle block, and a socket is provided on one side of the fixed mold. The position of the socket corresponds to the position of one end of the inclined groove. The movable mold is fixedly connected to one end of the insert block, and the position of the insert block corresponds to the socket. During the entire process of the movable mold approaching the fixed mold until the mold is closed, one end of the insert block continuously approaches the socket, and the insert block passes through the socket, so that the protrusion enters the inclined groove. During the process of the insert block continuing to move, the right-angle block slides into the rectangular cavity through the cooperation of the protrusion and the inclined groove, thereby compressing the spring 1 fixedly connected to the right-angle block. At the same time, due to the movement of the right-angle block, the feed port is exposed to facilitate material pouring. When the movable mold moves in the opposite direction and leaves the fixed mold, it is acted upon by the spring 1 and the protrusion to move the right-angle block outward from the rectangular cavity, thereby covering the feed port to prevent impurities from entering.

[0013] 2. The four sliders are each provided with an inclined surface 1 and an inclined surface 2. The four sliders are arranged in a rectangular shape. The inclined surface 1 and the inclined surface 2 between two adjacent sliders abut against each other, so that when the cylinder is extended, a slider fixedly connected to the output end of the cylinder slides in the slide groove, and the abutment of the inclined surface 1 and the inclined surface 2 of the other slider makes the other slider slide in the slide groove. Since the four sliders are arranged in a rectangular shape, the four sliders can be made to slide in the slide groove at the same time through transmission, and the sliding directions of the two adjacent sliders are perpendicular to each other. Since the fixed mold is fixedly connected to the upper end of the base and the movable mold is fixedly connected to the slider, when the slider slides, it drives the movable mold fixedly connected thereto to slide together, thereby making the movable mold fit with the fixed mold to achieve the effect of mold closing. In this way, the four molds can be closed at the same time, which makes the work efficiency higher and more energy-saving.

[0014] 3. Ejector rods are slidably connected to both sides of the movable mold. Spring three is sleeved on the ejector rods, and a baffle is fixedly connected to the base. When the die-casting is completed, the movable mold moves away from the fixed mold, so that one end of the ejector rod abuts against the baffle. During the continued movement, spring three is compressed and the ejector rod slides, thereby ejecting the finished die-cast product for easy demoulding. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0019] Reference Figure 1-2 As shown, a multi-slider high-precision and high-speed die-casting machine includes a base 1, four mold assemblies 2 are connected to the base 1, the lower ends of the four mold assemblies 2 are fixedly connected to a driving assembly 3, the four mold assemblies 2 are slidably connected to a feed port covering assembly 4, a pushing assembly 5 is fixedly connected to the base 1, and a limiting assembly 6 is rotatably connected to the base 1.

[0020] Four mold assemblies 2 are connected to the base 1 so that the position of the mold assembly 2 is more stable during operation. The lower ends of the four mold assemblies 2 are fixedly connected to the driving assembly 3 so that the driving assembly 3 can drive the four mold assemblies 2 to perform die-casting at the same time, which makes the work efficiency higher and improves the productivity. The four mold assemblies 2 are all slidably connected to the feed port covering assembly 4 to prevent other impurities from entering and affecting the quality of the product. The base 1 is rotatably connected to the limiting assembly 6 to make the connection of the mold assembly 2 more firmly during die-casting.

[0021] Reference Figure 3 As shown, a driving cavity 11 is provided at the lower end of the base 1, and the driving assembly 3 includes: a rectangular block 31, the rectangular block 31 is fixedly connected in the driving cavity 11, four sliding grooves 32 are provided on the rectangular block 31, and sliders 33 are slidably connected to the four sliding grooves 32, and the side surfaces of two sliders 33 are fixedly connected to the output ends of cylinder 1 34, and the other end of cylinder 1 34 is fixedly connected to the side surface of the driving cavity 11.

[0022] A rectangular block 31 is fixedly connected to the driving chamber 11 so that the position of the rectangular block 31 in the driving chamber 11 is stable. Slide blocks 33 are slidably connected to the four slide grooves 32. Since the position of the rectangular block 31 is stable, the position of the slide blocks 33 is more stable when sliding in the slide grooves 32. The side surfaces of the two slide blocks 33 are fixedly connected to the output ends of the cylinder 1 34. The other end of the cylinder 1 34 is fixedly connected to the side surface of the driving chamber 11, so that when the cylinder 1 34 extends and contracts, it drives the slide blocks 33 fixedly connected to the output ends of the cylinder to slide in the slide grooves 32.

[0023] The four sliders 33 are all provided with a slope 1 331 and a slope 2 332. The four sliders 33 are arranged in a rectangular shape. The slope 1 331 and the slope 2 332 abut against each other between two adjacent sliders 33. The mold assembly 2 includes: a fixed mold 21 and a movable mold 22. The fixed mold 21 is fixedly connected to the upper end of the base 1, and the movable mold 22 is fixedly connected to the slider 33.

[0024] The first and second inclined surfaces 331 and 332 of the four sliders 33 are arranged in a rectangular shape. The first inclined surface 331 and the second inclined surface 332 of two adjacent sliders 33 abut against each other, so that when the cylinder is extended, one slider 33 fixedly connected to the output end of the cylinder slides in the slide groove 32, and the abutment between the first inclined surface 331 and the second inclined surface 332 of the other slider 33 causes the other slider 33 to slide in the slide groove 32. Since the four sliders 33 are arranged in a rectangular shape, the four sliders 33 can be driven to slide in the slide groove 32 at the same time, and the sliding directions of the two adjacent sliders 33 are perpendicular to each other. Since the fixed mold 21 is fixedly connected to the upper end of the base 1 and the movable mold 22 is fixedly connected to the slider 33, when the slider 33 slides, it drives the movable mold 22 fixedly connected thereto to slide together, thereby making the movable mold 22 fit with the fixed mold 21, achieving the mold closing effect. In this way, the four molds can be closed at the same time, which makes the work efficiency higher and more energy-saving.

[0025] Reference Figure 4 As shown, an operating port 211 is provided on one side of the fixed mold 21, a rectangular cavity 212 is provided at the upper end of the operating port 211, a feed port 213 is provided in the operating port 211, a push port 214 is also provided on the side of the fixed mold 21, an exhaust port 215 is provided at the upper end of the fixed mold 21, and an exhaust pipe 216 is fixedly connected to the exhaust port 215.

[0026] A rectangular cavity 212 is provided at the upper end of the operating port 211, so that when the mold is closed, the feed port covering component 4 is retracted into the rectangular cavity 212, thereby exposing the feed port 213 to facilitate pouring the liquid material. After the liquid material is poured in, the liquid material is pushed into the fixed mold 21 through the action of the pushing component 5. At the same time, after the liquid material enters the fixed mold 21, it squeezes out the gas in the fixed mold 21, and the gas enters the exhaust pipe 216 from the exhaust port 215 and is discharged.

[0027] Reference Figure 5As shown, the material port covering assembly 4 includes: a right-angle block 41, which is slidably arranged in the operating port 211, and one end of the right-angle block 41 is slidably connected in the rectangular cavity 212, and both sides of one end of the right-angle block 41 are fixedly connected to one end of a spring 42, and the other end of the spring 42 is fixedly connected to the bottom of the operating port 211, and an inclined groove 411 is provided on the upper surface of the right-angle block 41, and a socket 217 is provided on one side of the fixed mold 21, and the position of the socket 217 corresponds to the position of one end of the inclined groove 411, and the movable mold 22 is fixedly connected to one end of the plug block 43, and the plug block 43 corresponds to the position of the socket 217, and the lower surface of one end of the plug block 43 is fixedly connected with a protrusion 431.

[0028] Since the right-angle block 41 is slidably arranged in the operating port 211, one end of the right-angle block 41 is slidably connected to the rectangular cavity 212, both sides of one end of the right-angle block 41 are fixedly connected to one end of the spring 1 42, and the other end of the spring 1 42 is fixedly connected to the bottom of the operating port 211. An inclined groove 411 is provided on the upper surface of the right-angle block 41, and a socket 217 is provided on one side of the fixed mold 21. The position of the socket 217 corresponds to the position of one end of the inclined groove 411. The movable mold 22 is fixedly connected to one end of the plug block 43, and the position of the plug block 43 corresponds to the position of the socket 217. During the entire process of the movable mold 22 approaching the fixed mold 21 until the mold closing is completed, one end of the plug block 43 continuously moves toward the socket 217. 17 approaches, the insert block 43 passes through the socket 217, so that the protrusion 431 enters the inclined groove 411. During the continued movement of the insert block 43, the cooperation between the protrusion 431 and the inclined groove 411 causes the right-angle block 41 to slide into the rectangular cavity 212, thereby compressing the spring 1 42 fixedly connected to the right-angle block 41. At the same time, due to the movement of the right-angle block 41, the feed port 213 is exposed to facilitate pouring. When the movable mold 22 moves in the opposite direction and leaves the fixed mold 21, it is acted upon by the spring 1 42 and the protrusion 431, so that the right-angle block 41 moves outward from the rectangular cavity 212, thereby covering the feed port 213 to prevent impurities from entering.

[0030] A rack 61 is fixedly connected to one side of the movable mold 22, so that the movable mold 22 can drive the rack 61 fixedly connected thereto to move together when it moves. One end of the rotating shaft 62 is fixedly connected to a gear 63. When the rack 61 moves to a position where it meshes with the gear 63, in the process of continuing to move, the gear 63 rotates through the meshing effect of the gear 63 and the rack 61, thereby driving the rotating shaft 62 fixedly connected to the gear 63 to rotate on the base 1, thereby driving the connecting rod 64 to rotate together, driving the connecting rod 64 at the other end The connected roller 65 rotates, and when the mold is closed, the roller 65 just abuts against the outer side of the movable mold 22. During the rotation of the connecting rod 64, when the connecting rod 64 rotates to the position of the limit rod 66, the limit rod 66 is pushed downward, and the spring 2 67 is compressed. When one end of the hemispherical 661 of the limit rod 66 corresponds to the position of the limit hole 641, the spring 2 67 is reset, and the upper end of the limit rod 66 is inserted into the limit hole 641. At this time, the roller 65 just abuts against the outer side of the movable mold 22, fixing the movable mold 22.
