[0051] Working principle: First, place the mold filled with sand and gravel powder originally used for ductile iron manhole cover at the starting point on one side of the conveying component 2, and then control the operation line to start the operation through the control panel 3, and the conveying component 2 drives the mold to the bottom of the pressure plate 6 of the die holder 4. When the mold moves close to the die holder 4, the sensor head 403 senses that the mold is approaching. At this time, the baffle 702 on one side of the support plate 7 is driven by the electric rotating rod to control the angle in the groove 701, so that it is perpendicular to the groove 701, which can limit the mold on the support plate 7. Then the slide 5 moves up and down in the slide groove 402 to control the height of the pressure plate 6, and controls its pressure plate 6 to press the mold downward based on the hydraulic cylinder 501. After the die pressing operation is completed, the conveying component 2 drives the mold to move to the bottom of the pressure plate 6 under the control of the control panel 3. The conveying component 2 moves toward the fixing part 8, and the sensing bar 802 at the lower end of the scraping bar 801 of the fixing part 8 senses the height of the mold, and the control system controls the hydraulic cylinder 2 803 to control the height of the scraping bar 801, and based on the scraping bar 801, the sand and stone powder overflowed from the mold due to compaction is scraped off, and then the conveying component 2 is pushed to the casting component 10, and the casting component 10 sends the container 11 filled with molten iron to the vicinity of the pushing component 9, and the control system controls the hydraulic cylinder 3 1202 to insert the insertion rod into the socket 1102 on the side of the corresponding sliding bar 1101. The manual operation only needs to adjust the tilt of the container 11 through the rocker 12 to allow the solution to enter the mold, and finally the pushing component 9 sends the mold out of the operating table 1 for cooling and demolding.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
