Both the moving mold core 8 and the fixed mold core 9 are fitted with cavities to accommodate the product 7. Through the cooperation of the fixed mold assembly, the moving mold assembly, and the cavity structure, it is easy to freely change the cavity structure of different cavities according to the components required by the combined impeller, thereby using the same frame to produce different products 7, which improves practicality.
[0015] In this utility model, to solve the problems of high cost of frequently using matching mold frames and low efficiency of manual demolding in existing molding structures, the following technical solution is adopted: The ejection assembly includes a lower ejector plate 10, the bottom surface of which abuts against the top surface of the base plate 1. An upper ejector plate 11 is fixedly connected to the top surface of the lower ejector plate 10 by bolts. A support block 12 is fixedly installed on the outer periphery of the top surface of the upper ejector plate 11 by bolts. A round ejector pin 14 is clamped in the middle of the top surface of the upper ejector plate 11 through a countersunk hole. The top of the round ejector pin 14 passes through the moving mold plate 3 and the moving mold core 8 to abut against the product 7. Ejector pin guide posts 13 are clamped in the front and rear sides of the top surface of the upper ejector plate 11 through countersunk holes. The moving mold assembly includes a moving mold plate 3, and an ejector pin guide post 13 is installed on the top surface of the moving mold plate 3 aligned with the position of the ejector pin guide post 13. The device includes an ejector guide sleeve 15, a moving mold plate 3 connected to an opening and closing guide post 16 via a countersunk hole, a moving mold core 8 fixedly installed in the middle of the top surface of the moving mold plate 3 by bolts, a moving mold assembly including a fixed mold plate 4, an opening and closing guide sleeve 18 fitted on the bottom surface of the fixed mold assembly to match the opening and closing guide post 16, a fixed mold core 9 fixedly installed on the bottom surface of the fixed mold plate 4 by bolts, a runner assembly including a runner plate 5, a cold runner 20 fitted inside the runner plate 5, the bottom end of the cold runner 20 penetrating the fixed mold core 9, the top end of the cold runner 20 penetrating the top plate 6 and fixedly connected to a runner ring 19, and lifting rings 17 fixedly installed on the left and right sides of the outer surfaces of the moving mold plate 3 and the fixed mold plate 4. Through the cooperation of the ejector assembly and the runner assembly, the device can be integrated with the extrusion system to produce product 7, improving the efficiency of use.
[0016] Working Principle: When using this utility model, firstly, the corresponding cavity structure (including the moving mold core 8 and the fixed mold core 9 that cooperate with product 7) is replaced according to the required finished product. Then, the device consisting of the base plate 1, square iron 2, moving mold plate 3, fixed mold plate 4, runner plate 5, and top plate 6 is fixedly installed on the extruder. Next, the extruder outlet is connected to the runner ring 19 on the runner plate 5, and the water system connected to the internal water channels of the moving mold plate 3 and the fixed mold plate 4 is connected. Finally, the moving mold assembly, including the moving mold plate 3, the moving mold core 8, and the opening and closing guide post 16, is fixedly installed on the hydraulic opening and closing mold system, and molding can begin. After starting the hydraulic press, the moving mold plate 3 moves forward under the drive and closely adheres to the fixed mold plate 4. At this time, the opening and closing guide post 16 on the moving mold plate 3 and the opening and closing guide sleeve 18 on the fixed mold plate 4 are precisely engaged, so that the moving mold core 8 and the fixed mold core 9... The extruder closes to form a sealed cavity that fits the product 7. Then, the extruder sends the molten metal through the runner ring 19 into the cold runner 20 in the runner plate 5, and then through the bottom end of the cold runner 20 into the cavity formed by the moving mold core 8 and the fixed mold core 9. Subsequently, the water system sends cooling water into the water channels inside the moving mold plate 3 and the fixed mold plate 4 to quickly cool the molten metal in the cavity to form the finished product. After molding is completed, the hydraulic system pulls back the moving mold plate 3. Since the bottom surface of the lower ejector plate 10 in the ejection assembly abuts against the top surface of the base plate 1 and remains in the same position, the round ejector pin 14 on the top surface of the upper ejector plate 11, guided by the ejector guide post 13 and the ejector guide sleeve 15 on the moving mold plate 3, continuously penetrates the moving mold plate 3 and the moving mold core 8 with its top end and ejects the finished product out of the moving mold core 8, completing the one-time molding operation. This one-piece molding process greatly improves production efficiency.
[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
