[0003] The existing patent (publication number: CN220943072U) discloses a clay sand line flat plate type part casting mold, which solves the problem of random generation of bubbles in the part pouring process, and comprises a mold plate and a mold plate. The mold plate is a square body, and the lower plane is open to facilitate the embedding of the mold plate into the mold plate. The center of one end of the outer side of the mold plate protrudes outward, two inclined surfaces are arranged on the protruding surface towards the two ends, the protruding surface is the highest point of the inclined surface, and two part models are arranged on each inclined surface. Each group of part models is symmetrical about the protruding surface. The upper plane of the mold plate is a pouring surface, the pouring surface is recessed inward, a horizontal gate is arranged at the center of the pouring surface, the horizontal gate and the protruding surface of the mold plate are in corresponding position, two inclined surfaces are arranged on both sides of the horizontal gate as the center, the horizontal gate is the lowest point, and the two inclined surfaces of the pouring surface are parallel to the two inclined surfaces of the mold plate. The generation of bubbles is reduced, and the bubbles are concentrated at the highest point for easy maintenance.

[0004] The above-mentioned comparative document points out that the device can reduce the random generation of bubbles in the part pouring process, and the generated bubbles are concentrated at the highest point for easy maintenance and cleaning. However, in actual operation, the concentration degree and position of the bubbles may be affected by various factors such as pouring speed, temperature and alloy composition. If the bubbles cannot be effectively concentrated or treated in time, they may still have adverse effects on the quality of the castings. Practical new type content

When the metal liquid is poured, the generated gas can be guided to the exhaust hole reserved rod through the air guide strip for discharge, thereby reducing the bubbles and pores in the casting and improving the quality of the casting. The design of the pouring channel enables the metal liquid to flow smoothly and uniformly into the mold, reducing the turbulence and splashing in the pouring process, which helps to reduce the possibility of bubble generation and improve the pouring efficiency.

[0035] It should be noted that the upper end of the pouring hole reserved rod 7 is tapered from wide to narrow, so that the metal liquid can be poured easily.

[0036] The working principle of the above embodiment is as follows:

[0037] Firstly, the mold is flipped to place the lower sand box inside the lower positioning groove 17, and add and tamp the sand inside the sand box, then the mold is flipped together with the lower sand box, gently knock the mold to separate it from the sand, then the mold is removed, and the upper sand box is placed inside the upper positioning groove 16, and sand is added and tamped inside the upper sand box, and the pouring hole reserved rod 7 and the exhaust hole reserved rod 9 are removed by rotating the handle 11 and the knob 12, so that a pouring hole and four exhaust holes are formed in the upper sand box, when the upper and lower sand boxes are filled and tamped with sand, and the pouring hole reserved rod 7 and the exhaust hole reserved rod 9 have been removed from the mold, the upper sand box is flipped and placed on the upper end of the lower sand box, so that a complete casting cavity is formed between the upper and lower sand boxes, ready for pouring of the metal liquid, after the sand box is sealed, during pouring, the metal liquid is poured into the position originally occupied by the pouring hole reserved rod 7, i.e. the pouring hole, through the pouring equipment preheated to an appropriate temperature, slowly and uniformly, because the pouring hole reserved rod 7 is designed to be tapered with the upper part being wide and the lower part being narrow, this shape helps the metal liquid to flow smoothly into the pouring channel 2, reducing resistance and splashing during pouring, at the same time, under the guidance of the channel formed by the pouring channel 2 and the flow guide strip 14, the metal liquid can be uniformly distributed to each part model 13 at the bottom end of the mold plate 1, during pouring, a large amount of gas will be generated by the metal liquid, if these gases are not discharged in time, they will form bubbles and pores in the casting, affecting the quality of the casting, the design of the gas guide strip 3 and the exhaust hole reserved rod 9 provides an effective discharge path for the gas, when the metal liquid flows through the gas guide strip 3, the gas generated will be guided to the exhaust hole reserved rod 9, and will be smoothly discharged out of the mold through the exhaust hole, thereby effectively reducing the bubbles and pores in the casting, during pouring, attention should be paid to control the pouring speed and pouring temperature to avoid defects caused by too fast pouring or too high temperature, after the metal liquid is completely poured and fills the casting cavity, a period of time is needed to allow the metal liquid to cool and solidify, during this process, the metal liquid will gradually solidify into a casting and form an integral part with the surrounding sand, when the casting is completely solidified, the subsequent demolding and cleaning work can be carried out, at this time, the operator needs to first remove the upper sand box from the upper end of the lower sand box, then gently knock the lower sand box to separate the casting from the sand, finally, the removed casting is cleaned and inspected to remove the surface sand and burrs, and to check whether the casting has defects or cracks, if the quality of the casting meets the requirements, subsequent processing or use can be carried out.
