Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, and in particular to a die casting machine feeding device. Background Technology

[0002] Die casting machines are used for pressure casting. They mainly include two types: hot chamber and cold chamber. Each type is further divided into vertical and horizontal types. Die casting machines are mainly composed of mold clamping mechanism, injection mechanism, hydraulic system and power control system. In addition, they also include key components such as die casting mold, cooling system, spraying system and injection system. The working principle of die casting machines is to use high pressure to inject molten metal material into the die casting mold cavity. After a certain period of cooling and solidification, the formed metal part is taken out of the mold. This process is often used to manufacture various metal parts, such as automobile engine housings, motorcycle parts, electrical appliance housings, etc.

[0003] The utility model patent with publication number CN212019337U discloses a feeding device for a die-casting machine. It states that "by setting up a cleaning pump, a feeding pipe, and a water outlet pipe, high-pressure water can be used to flush the inner wall of the feeding pipe when regular cleaning is needed, cleaning away any residue left by the raw material, preventing blockage, and ensuring the machine's efficiency and lifespan." While this solves the problem that "in existing die-casting machines, raw materials accumulate in the hopper after entering through the feeding pipe without cleaning, easily causing blockage or reduction in the inner diameter of the feeding pipe, reducing machine efficiency, and even damaging the die-casting machine," the inner wall of the feeding pipe may wear down due to prolonged contact with the raw material, resulting in poor feeding or uneven inner wall, thus affecting the quality of the die-cast products. Currently, replacing the feeding pipe using cutting and welding methods is cumbersome and time-consuming. Therefore, this new feeding device for a die-casting machine is proposed. Utility Model Content

[0011] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, a plurality of insert plates are slidably connected to the inner cavities of a plurality of slots, and a groove is provided at one end of each insert plate.

[0012] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, the rotating ring has multiple built-in grooves inside, one side of the inner wall of the built-in groove has a through hole, and a movable piece is slidably connected to the inner cavity of the built-in groove.

[0013] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, a wedge block is fixedly connected to one side of the moving plate, and two spring plates are connected between the other side of the moving plate and the inner wall of the built-in groove.

[0014] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, a fixing plate is fixedly connected to the middle of the other side of the moving plate. One end of the fixing plate movably penetrates the inner wall of the built-in groove to the outside of the rotating ring and has a limit hole.

[0015] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, the anti-rotation component includes a plurality of fixing blocks fixedly connected to the mounting plate, the surface of the fixing blocks is provided with a sliding groove, and the surface of the mounting plate is movably fitted with a movable ring.

[0016] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, a plurality of sliders are fixedly connected to the inner sidewall of the movable ring, and the sliders are slidably connected to the inner cavity of the opposite groove.

[0017] In a preferred embodiment of the die-casting machine feeding device provided by this utility model, a plurality of limiting rods are fixedly connected to one side wall of the movable ring, and one end of the limiting rod movably passes through the inner cavity of the corresponding limiting hole.

[0018] As a preferred embodiment of the die-casting machine feeding device provided by this utility model, the fixing component includes two lower blocks and two through holes.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a feeding device for a die-casting machine. The feeding pipe is combined with the mounting plate via an insert plate and a slot. This separate design facilitates timely disassembly and replacement when the feeding pipe wears out. When the feeding pipe is combined with the mounting plate, rotating the rotating ring causes the wedge-shaped block placed in the inner cavity of the ring groove to contact one end of the insert plate. Under the action of the spring plate, part of the wedge-shaped block retracts into the inner groove. When it is aligned with the groove, a reset operation is performed, allowing part of the wedge-shaped block to enter the inner cavity of the groove, thereby positioning the feeding pipe and preventing it from detaching from the mounting plate during operation. The operation is simple, and when the feeding pipe wears out, it can be quickly disassembled and replaced, reducing maintenance costs and time.

[0021] This utility model provides a feeding device for a die-casting machine. After multiple wedge blocks position the feed tube through grooves on multiple insert plates, the positions of the limiting holes on multiple fixed plates correspond to the positions of multiple limiting rods. The movable ring moves, and under the action of the sliding groove and the slider, the multiple limiting rods move to one side of the ring groove until the multiple limiting rods pass through the inner cavity of the multiple limiting holes. This design can prevent the ring groove from being affected by external forces and thus release the positioning of the feed tube, strengthening the connection between the feed tube and the mounting plate. The locking mechanism of the wedge blocks and grooves provides the first layer of locking, while the combination of the limiting rods and limiting holes provides the second layer of locking, enhancing the stability of the connection.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A die-casting machine feeding device includes a mounting plate 1, a drive unit 2 mounted on one side wall of the mounting plate 1, the drive unit 2 being a cylinder that provides driving force for the movement of a piston 3, the output end of the drive unit 2 movably penetrating the surface of the mounting plate 1 and being connected to the piston 3 via transmission, a feeding pipe 4 provided on one side of the mounting plate 1, an installation hole 5 opened on one side of the surface of the feeding pipe 4, a storage bin 6 provided at the top of the feeding pipe 4, a connecting pipe 7 connected to the bottom end of the storage bin 6, the connecting pipe 7 having a valve, and one end of the connecting pipe 7 being placed in the inner cavity of the installation hole 5;

[0033] Connector 8 is placed between feed pipe 4 and mounting plate 1. The surface of feed pipe 4 is provided with positioning component 9, which includes an annular groove 91 and a rotating ring 92. The annular groove 91 is opened on the other side of the surface of feed pipe 4, and the rotating ring 92 is movably connected to the inner cavity of the annular groove 91. The surface of mounting plate 1 is provided with anti-rotation component 10, and the bottom of storage bin 6 is provided with fixing component 11.

[0034] In the embodiments of this application, the connector 8 includes multiple insert plates 81 and multiple slots 82. The multiple insert plates 81 and multiple slots 82 are arranged in a ring array and their shapes are adapted to each other. The inner cavity of the slot 82 is connected to the inner cavity of the ring groove 91. The separate design of the mounting plate 1 and the feed tube 4 facilitates the subsequent replacement and disassembly of the feed tube 4. One end of the multiple insert plates 81 is fixedly connected to the surface of the mounting plate 1. The multiple slots 82 are opened at one end of the feed tube 4. The multiple insert plates 81 are slidably connected to the inner cavities of the multiple slots 82 respectively. A groove 83 is opened at one end of the insert plate 81. Multiple built-in grooves 93 are opened inside the rotating ring 92. A through hole 94 is opened on one side of the inner wall of the built-in groove 93 and is connected to the outside. A movable piece 95 is slidably connected to the inner cavity of the built-in groove 93. A wedge block 96 is fixedly connected to one side of the movable piece 95. The multiple wedge blocks 96 are arranged in a ring array and their inclined surfaces face opposite directions. The other side of the movable piece 95 is connected to the built-in groove. Two spring plates 97 are connected between the inner walls of 93, which facilitates the wedge block 96 to retract into the inner groove 93 under pressure and reset when it corresponds to the position of the groove 83, thus achieving the purpose of positioning the feed tube 4. A fixing plate 98 is fixedly connected to the middle of the other side of the moving plate 95. One end of the fixing plate 98 moves through the inner wall of the inner groove 93 to the outside of the rotating ring 92 and has a limit hole 99. The fixing component 11 includes two lower blocks 111 and two through holes 112. The tops of the two lower blocks 111 are fixed to the two sides of the bottom of the storage bin 6 respectively. A through plate 113 is opened on the surface of the lower block 111. One end of the two through holes 112 is fixedly connected to the mounting plate 1, and the other end of the through hole 112 moves through the inner cavity of the opposite through plate 113. The lower block 111 is fixedly connected to the through hole 112 by screws to ensure the stability of the storage bin 6 after it is connected to the feed tube 4. The screw fixing method facilitates the subsequent disassembly of the storage bin 6 to replace the feed tube 4.

[0035] In the embodiments of this application, the anti-rotation component 10 includes a plurality of fixing blocks 101 fixedly connected to the mounting plate 1. The surface of the fixing block 101 is provided with a sliding groove 102, which is T-shaped. The surface of the mounting plate 1 is movably fitted with a movable ring 103. The inner sidewall of the movable ring 103 is fixedly connected with a plurality of sliders 104, which are T-shaped. The T-shaped design can prevent the sliders 104 from disengaging from the sliding groove 102, and there is a certain friction between them to prevent the movable ring 103 from moving arbitrarily. The sliders 104 are slidably connected to the inner cavity of the corresponding sliding groove 102. A plurality of limiting rods 105 are fixedly connected to one side wall of the movable ring 103 to prevent the ring groove 91 from rotating under external force. One end of the limiting rod 105 movably passes through the inner cavity of the corresponding limiting hole 99.

[0036] The following is the usage process of the die-casting machine feeding device provided by this utility model: First, after the feeding pipe 4 is severely worn, the operator first rotates the screw to release the fixed connection between the lower block 111 and the through hole 112, and then moves the movable ring 103 so that multiple limiting rods 105 disengage from the inner cavity of the limiting hole 99, and at the same time, the through hole 112 disengages from the inner cavity of the through plate 113. At this time, the operator can first remove part of the storage bin 6 from the feeding pipe 4, and then rotate the rotating ring 92 counterclockwise so that multiple wedge blocks 96 are forced to retract into the inner groove 93, and the spring plate 97 is in a compressed state. After the part of the insert plate 81 is disengaged, the positioning of the feeding pipe 4 is released. Then, the operator manually pulls the feeding pipe 4 away from the mounting plate 1, thus completing the disassembly of the feeding pipe 4. Then, the new feeding pipe 4 is reassembled with the storage bin 6 and the mounting plate 1.
