Description

Technical Field

[0001] The utility model relates to the technical field of ceramic molding dies, in particular to a ceramic core molding die with an exhaust function. Background Technique

[0002] A ceramic core die is a die dedicated to processing ceramic cores, mainly composed of an upper die, a lower die, a molding cavity and a grouting port. After the upper die and the lower die are closed subsequently, a cylindrical area can be formed in the molding cavity between the two, and then grouting is carried out through the grouting port to carry out the molding process of the ceramic core.

[0003] After retrieval, the Chinese patent number is CN219726671U, which includes an auxiliary flow channel mechanism arranged on the upper die of the ceramic core and a surrounding exhaust structure arranged between the upper die of the ceramic core and the lower die of the ceramic core. The auxiliary flow channel mechanism includes a side flow channel horizontally opened inside the upper die of the ceramic core. The auxiliary flow channel mechanism further includes a downstream flow channel opened at the bottom of the side flow channel. The auxiliary flow channel mechanism further includes a manual plugging structure. By adding an auxiliary flow channel mechanism and a surrounding exhaust structure to the existing ceramic core die, the utility model can, during grouting, through the auxiliary drainage of the auxiliary flow channel mechanism, directly drain the slurry to the difficult-to-form areas at both ends of the molding cavity, thereby improving the molding quality, facilitating the high-quality molding of the ceramic core, and can select to plug some of the downstream flow channels according to the actual molding requirements, with high flexibility in use. At the same time, it can quickly discharge the gas in the molding cavity during molding. However, when the upper die and the lower die are clamped, there will be a problem that the slurry enters the return air channel through the air guiding channel and then flows out from the exhaust channel, which will cause the phenomenon that the return air channel is blocked by the slurry for a long time, and finally lead to the result that the exhaust function of the device is limited, reducing the quality of the molded ceramic core. For this reason, we propose a ceramic core molding die with an exhaust function. Content of the Utility Model

The upper mold 9 is pushed by the electric push rod A8 to be clamped with the lower mold 5. At this time, the sealing ring 6 and the sealing groove 13 cooperate to ensure sealing. During the mold clamping process, the gas in the mold is discharged through the air vent groove 7 and the through hole C14. The compression spring 1803 in the self-adaptive exhaust assembly 18 is compressed under the action of the gas pressure, so that the moving plate 1805 drives the closing column 1806 to move upward, thereby realizing exhaust. After the gas is discharged, the compression spring 1803 rebounds to reset the closing column 1806 to prevent liquid leakage. After the molding is completed, the electric push rod B1701 pushes the ejecting plate 1702 to eject the formed ceramic core from the lower mold 5 to complete demolding. The closing and cleaning plate 1809 can clean the exhaust channel under the adjustment of the screw rod 1807 to ensure smooth exhaust. The utility model significantly improves the molding quality of the ceramic core. Due to the self-adaptive exhaust function, it can effectively discharge the gas in the mold, avoid defects such as pores and looseness caused by gas residue, and make the structure of the formed ceramic core more dense and uniform.
