Description

Technical Field

[0001] This utility model relates to the field of sand addition technology for molding machines, specifically a sand addition device for a vertical parting boxless injection molding machine. Background Technology

[0002] Molding machines are casting equipment mainly used to manufacture sand molds. During casting, sand needs to be added into the mold frame, so a molding machine with a sand adding device is required.

[0003] Currently, molding machines mainly use sand and gravel materials in the mold frame to form the shape during casting. Generally, sand needs to be added to the mold frame before casting. However, existing sand adding mechanisms usually add sand directly to the middle of the mold frame. This may result in uneven sand addition on the sides, which will affect the casting quality. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a sand-adding device for a vertical parting boxless injection molding machine, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model proposes a sand feeding device for a vertical parting boxless injection molding machine, including a machine housing, a storage bin at the top of the machine housing, and a feeding hopper fixedly installed at the bottom of the storage bin and inserted into and connected to the machine housing.

[0006] The inner wall of the housing is provided with a conveying mechanism, which includes a conveying sloping plate, a mounting plate, a moving block, a second electric cylinder and a mounting groove. A mounting groove is opened on one side of the inner wall of the housing. A moving block is slidably connected to the inner wall of the mounting groove. A mounting plate is fixedly installed on one side of the moving block. A conveying sloping plate is fixedly installed on the top of the mounting plate.

[0007] In one example, a second fixing rod is fixedly installed on both sides of the hopper, and a connecting plate is rotatably connected to the ends of the two second fixing rods that are far apart from each other.

[0008] In one example, a sealing plate is fixedly installed on one side of each of the two connecting plates that are close to each other, and the sealing plate is in contact with the bottom of the hopper.

[0009] In one example, the other side of the hopper is rotatably connected to a first fixed rod, and the two ends of the first fixed rods that are far apart from each other are rotatably connected to a horizontal plate, and the two horizontal plates are rotatably connected to a sealing plate.

[0010] In one example, a first electric cylinder is fixedly installed at the center of both sides of the bottom of the hopper, and both first electric cylinders are hinged to the cross plate.

[0011] In one example, a mold frame is provided at the bottom of the inner wall of the housing, and a pressure plate is provided on the inner wall of the housing, and the pressure plate is adapted to the mold frame.

[0012] The sand feeding device for a vertical parting boxless injection molding machine proposed in this utility model can bring the following beneficial effects:

[0013] 1. The sand-adding device of the vertical parting boxless injection molding machine, by activating the second electric cylinder, drives the moving block to move in the mounting groove, which in turn drives the mounting plate to move, which in turn drives the material conveying sloping plate to move. This allows the material conveying sloping plate to move and convey material, so as to uniformly add sand to the mold frame and avoid uneven sand addition in subsequent processes, which would affect the quality of the casting.

[0014] 2. The sand-adding device of the vertical parting boxless injection molding machine is activated by starting the first electric cylinder to drive the horizontal plate to move around the first fixed rod, which in turn drives the sealing plate to move. At this time, the bottom of the hopper is opened, and the material in the storage bin is transported to the conveying inclined plate, and then transported to the mold frame to complete the sand-adding step.

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, an embodiment of this utility model proposes a sand feeding device for a vertical parting boxless injection molding machine, including a machine housing 1, a storage bin 2 on the top of the machine housing 1, and a feeding hopper 3 that is inserted and connected to the machine housing 1 at the bottom of the storage bin 2.

[0024] The inner wall of the housing 1 is provided with a conveying mechanism, which includes a conveying sloping plate 9, a mounting plate 10, a moving block 11, a second electric cylinder 12, and a mounting groove 13. A mounting groove 13 is provided on one side of the inner wall of the housing 1. The moving block 11 is slidably connected to the inner wall of the mounting groove 13. The mounting plate 10 is fixedly installed on one side of the moving block 11. The conveying sloping plate 9 is fixedly installed on the top of the mounting plate 10.

[0025] Specifically, a second fixing rod 7 is fixedly installed on both sides of the hopper 3. The ends of the two second fixing rods 7 that are far apart from each other are rotatably connected to a connecting plate 8. The connecting plate 8 is fixed by the second fixing rod 7, and the connecting plate 8 is fixed to the sealing plate 16.

[0026] Specifically, sealing plates 16 are fixedly installed on the sides of the two connecting plates 8 that are close to each other. The sealing plates 16 are in contact with the bottom of the hopper 3, and the bottom of the hopper 3 is sealed by the sealing plate powder 16.

[0027] Specifically, the other side of both sides of the feeding hopper 3 is rotatably connected to the first fixing rod 6. The two ends of the first fixing rod 6 that are far apart from each other are rotatably connected to the horizontal plate 5. The two horizontal plates 5 are rotatably connected to the sealing plate 16. The horizontal plates 5 are fixed by the first fixing rod 6. The movement of the horizontal plate 5 drives the sealing plate 16 to move, thereby opening the bottom of the feeding hopper 3 for feeding.

[0028] Specifically, a first electric cylinder 4 is fixedly installed on the middle of both sides of the bottom of the hopper 3. Both first electric cylinders 4 are hinged to the horizontal plate 5. The horizontal plate 5 is moved by starting the first electric cylinder 4.

[0029] Specifically, the bottom of the inner wall of the housing 1 is provided with a mold frame 14, and the inner wall of the housing 1 is provided with a pressure plate 15. The pressure plate 15 is adapted to the mold frame 14. The sand and gravel material is stored through the mold frame 14 and die-cast by the pressure plate 15.

[0030] Working principle: When material needs to be fed, the first electric cylinder 4 is activated to drive the horizontal plate 5 to move around the first fixed rod 6, which in turn drives the sealing plate 16 to move. When the sealing plate 16 moves, the connecting plate 8 moves around the second fixed rod 7, thereby opening the bottom of the feeding hopper 3 and conveying the material in the storage bin 2 to the conveying inclined plate 9, and then to the mold frame 14 for sand addition. Subsequently, the pressure plate 15 moves downward to die-cast the material in the mold frame 14 to form it. At the same time, when the conveying inclined plate 9 is conveying material, the second electric cylinder 12 is activated to drive the moving block 11 to move in the mounting groove 13, and the mounting plate 10 drives the conveying inclined plate 9 to move, so that the material is evenly conveyed into the mold frame 14, thereby evenly adding sand to it.
