Description

Technical Field

[0001] The invention relates to the technical field of die-casting machines, in particular to a die-casting machine with an automatic feeding mechanism. Background Art

[0002] A die-casting machine is an industrial casting machine that hydraulically injects molten metal into a mold under pressure, cools it and forms it, and then opens the mold to obtain a solid metal casting. It does this by filling a certain amount of liquid metal into the mold cavity under high pressure and high speed, and rapidly solidifying it under pressure.

[0003] Currently, there are two common ways of taking materials from die-casting machines. The first is manipulator taking materials: using a specially designed manipulator to accurately grab the parts after die-casting through programming and control systems. The manipulator can be flexibly adjusted according to the shape, size and position of the parts. For example, the patent with announcement number CN206794714U discloses a material unloading manipulator named die-casting machine. This patent uses a manipulator to take materials from the die-casting machine; the second is manual taking materials: the operator wears protective equipment, such as high-temperature resistant gloves, etc., and directly takes out the parts from the mold after the mold is opened.

[0004] If a robot is used to pick up materials, although this method is convenient and fast, the manufacturing cost of the robot is relatively high for the producer, which will increase the overall production cost. If materials are picked up manually, the efficiency is low and there will be certain risks for the workers. Summary of the invention

[0005] The object of the present invention is to provide a die-casting machine with an automatic unloading mechanism to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a die-casting machine with an automatic unloading mechanism, comprising a frame, a die-casting assembly is arranged on the frame, the die-casting assembly comprises a die-casting movable mold slidably connected to the frame and an ejector slidably connected in the die-casting movable mold, and also comprises a clamping jaw, the clamping jaw is movably mounted on the frame, and the movable stroke of the clamping jaw has a clamping position facing the die-casting on the die-casting movable mold and a delivery position for delivering the die-casting, when the clamping jaw is located at the clamping position, the ejector ejects the die-casting on the die-casting movable mold out of the die-casting movable mold into the clamping jaw; during the sliding process of the die-casting movable mold relative to the frame, the transmission assembly is used to enable the clamping jaw to switch between the clamping position and the delivery position.

[0010] Furthermore, the clamping jaws are a three-jaw chuck, and the three-jaw chuck is electrically driven to achieve synchronous closing or synchronous separation of each jaw.

[0011] Furthermore, a protective cover is provided on the clamping jaws. When the clamping jaws are clamping the die-casting, the clamping jaws may be damaged due to the overhigh temperature of the die-casting, and the protective cover can effectively protect the clamping jaws.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-9 The die-casting machine with an automatic unloading mechanism provided in an embodiment of the present invention comprises a frame 1, a die-casting assembly is arranged on the frame 1, the die-casting assembly comprises a die-casting movable mold 2 slidably connected to the frame 1 and an ejector pin slidably connected to the die-casting movable mold 2 (not shown in the figure, the ejector pin ejects the die-casting part 11 from the die-casting movable mold 2 as a prior art, which will not be described in detail here), and also comprises a clamp 3, the clamp 3 is movably mounted on the frame 1, and has a movement stroke of the clamp 3 that faces the die-casting part 1 on the die-casting movable mold 2 1 and a delivery station for delivering the die-casting part 11. When the clamping jaw 3 is located at the clamping station, the ejector pushes the die-casting part 11 on the die-casting movable mold 2 out of the die-casting movable mold 2 into the clamping jaw 3. During the sliding process of the die-casting movable mold 2 relative to the frame 1, the transmission component 4 is used to switch the clamping jaw 3 between the clamping station and the delivery station. A protective cover is provided on the clamping jaw 3. When the clamping jaw 3 clamps the die-casting part 11, the clamping jaw 3 may be damaged due to the excessive temperature of the die-casting part 11, and the protective cover can effectively protect the clamping jaw 3.

[0029] like Figure 6 The transmission assembly 4 includes a slide plate 41, a limit rod 42, a hollow rod 43, a guide member 44 and a collar 45. The slide plate 41 is fixedly connected to the die-casting movable mold 2; the limit rod 42 is fixedly connected to the slide plate 41, and a protrusion is fixedly arranged on the side surface of the limit rod 42; the hollow rod 43 is fixedly connected to the clamping claw 3, and a guide groove 5 is provided on the inner wall of the hollow rod 43. The guide groove 5 includes a vertical groove 51 and a spiral groove 52 connected to each other, and the protrusion is slidably connected in the guide groove 5; the guide member 44 is arranged on the frame 1, and an inclined slide groove 441 is provided on the guide member 44; the collar 45 is rotatably connected to the hollow rod 43, A slide rod 451 is fixedly connected to the collar 45, and the slide rod 451 is slidably connected in the inclined slide groove 441. The die-casting assembly also includes a hydraulic cylinder 12, a die-casting fixed mold 13 and a plurality of guide rods 14. The hydraulic cylinder 12 is fixedly mounted on the frame 1, wherein the hydraulic cylinder 12 includes a cylinder barrel and a piston rod, the cylinder barrel is fixedly mounted on the frame 1, the piston rod is slidably connected to the cylinder barrel, and the end of the piston rod away from the cylinder barrel is fixedly connected to the die-casting movable mold 2; the die-casting fixed mold 13 is fixedly mounted on the frame 1; a plurality of guide rods 14 are fixedly connected to the frame 1, and the die-casting movable mold 2 is slidably connected to each of the guide rods 14.

[0030] Working principle: after the die-casting fixed mold 13 and the die-casting movable mold 2 complete the die-casting of a die-casting part 11 (the clamping jaws 3 are in the delivery position to complete the delivery of the previous die-casting part 11), the die-casting fixed mold 13 will be fixed relative to the frame 1, and the die-casting movable mold 2 will slide relative to the frame 1, that is, away from the die-casting fixed mold 13. During this process, the hydraulic cylinder 12 provides power for the die-casting movable mold 2, and multiple guide rods 14 make the sliding of the die-casting movable mold 2 more stable. In the process of moving away from the die-casting fixed mold 13, the die-casting movable mold 2 will drive the slide plate 41 to slide horizontally relative to the frame 1, and the sliding movement will bring the limit rod 42 to move horizontally, and the limit rod 42 will bring the hollow rod 43 to move horizontally. The horizontal movement of the hollow rod 43 will bring the fixed sleeve and then the slide rod 451 to slide in the inclined slide groove 441 on the guide member 44. During this process, the fixed sleeve is displaced horizontally and vertically relative to the frame 1, and then the fixed sleeve brings the hollow rod 4 3 also moves in the vertical direction. The protrusion on the limit rod 42 will first cooperate with the spiral groove 52 in the hollow rod 43 to complete the movement of the clamping jaw 3 from the oblique upper side of the die-casting machine to the upper side of the die-casting machine. During this process, the hollow rod 43 rotates relative to the fixed sleeve and the limit rod 42, and then the protrusion on the limit rod 42 will continue to cooperate with the vertical groove 51 of the hollow rod 43, so that the hollow rod 43 fully falls. At this time, the clamping jaw 3 connected to the other end of the hollow rod 43 will slowly move from the upper side of the die-casting machine to the upper side of the die-casting machine. The die casting machine 11 is moved to the upper part of the die casting mold 2 and the lower part of the die casting machine 11 is moved to the lower part of the die casting machine 11. The upper part of the die casting mold 2 is moved to the clamping station. When the clamping jaws 3 move to the clamping station, the ejector pins in the die casting movable mold 2 will slide relative to the die casting movable mold 2, and the die casting part 11 will be pushed from the die casting movable mold 2 to the clamping jaws 3. Then the clamping jaws 3 complete the clamping and fixing of the die casting part 11. Similarly, the die casting movable mold 2 slides toward the die casting fixed mold 13. The clamping jaws 3 will move the die casting part 11 to the top of the die casting machine first, and then move from the top to the delivery station, and the clamping jaws 3 will drop the die casting part 11.

[0031] Compared with the prior art, the present invention provides a die-casting machine with an automatic unloading mechanism. The die-casting movable mold 2 will slide relative to the frame 1 after completing the die-casting work. During this process, the die-casting movable mold 2 moves with the clamping claw 3. The die-casting movable mold 2 completes a reciprocating sliding stroke, which will cause the clamping claw 3 to switch from the delivery station to the clamping station to complete the clamping of the die-casting 11 and then return to the delivery station to deliver the die-casting 11. During this process, the die-casting movable mold 2 provides power through the transmission assembly 4 so that the clamping claw 3 can switch between the delivery station and the clamping station. On the one hand, compared with the robotic arm, the cost of purchasing production equipment can be reduced. On the other hand, for manual material collection, the efficiency of material collection can be improved and the dangerous phenomenon of workers taking materials can be prevented.

[0032] Among them, Figure 8 and Fig. 9The clamping jaw 3 includes a casing 31, a fixed plate 32, a rotating plate 33 and a driving member 34. The casing 31 is fixedly mounted on the hollow rod 43; the fixed plate 32 is fixedly connected in the casing 31, and a plurality of limit slots 321 are provided on the fixed plate 32; the rotating plate 33 is rotatably connected in the casing 31, and a plurality of arc grooves 331 are provided on the rotating plate 33, and each arc groove 331 is slidably connected with a clamping member 6, and each clamping member 6 passes through the corresponding limit slot 321; the driving member 34 is fixedly mounted in the casing 31, and the driving member 34 drives the rotating plate 33 to rotate relative to the casing 31. Specifically, the driving member 34 is a driving motor, and the output shaft of the driving motor is coaxially and fixedly connected with the rotating plate 33.

[0033] Working principle: the clamping jaws 3 are in the clamping position. When the die-casting 11 abuts against the fixed plate 32, the output shaft of the driving motor drives the rotating plate 33 to rotate. The rotating plate 33 will rotate relative to the housing 31, while the fixed plate 32 is fixed relative to the housing 31. The clamping members 6 on the rotating plate 33 are limited by the upper limit slot 321 on the fixed plate 32, which will cause each clamping member 6 to slide along the arc direction of the arc slot 331 on the fixed plate 32. At this time, each clamping member 6 will move closer to each other until the die-casting 11 is clamped and fixed; the clamping jaws 3 are in the releasing position, and the output shaft of the driving motor drives the rotating plate 33 to rotate in the opposite direction relative to the clamping. This process will cause each clamping member 6 to move away from each other, and the die-casting 11 will fall from the clamping jaws 3.

[0034] In another embodiment provided by the present invention, the clamping jaw 3 is a three-jaw chuck (this is the prior art and will not be elaborated on here). The three-jaw chuck is electrically driven to achieve synchronous closing or synchronous separation of each jaw. When the three-jaw chuck is in the clamping process, the various jaws of the three-jaw chuck are synchronously closed to clamp and fix the die-casting 11. When the three-jaw chuck is in the delivery process, the various jaws of the three-jaw chuck are synchronously separated to release the clamping and fixation of the die-casting 11, and the die-casting 11 falls from the three-jaw chuck.

[0035] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
