As shown in fig. 1 to 3, the exhaust push rod for the mold comprises an exhaust push rod 4, wherein the exhaust push rod 4 is made of 45# or 65Mn steel. The exhaust push rod 4 is arranged in a die cavity of the die body 1 in a clearance fit mode, an exhaust groove 5 is formed in one end of the exhaust push rod 4, a limiting block 41 is arranged at the other end of the exhaust push rod 4, an exhaust channel 7 is formed in the middle portions of the exhaust push rod 4 and the limiting block 41, and the exhaust groove 5 is communicated with the exhaust channel 7.
The limiting block 41 is arranged in a counter bore on the first push plate 2, and the limiting block 41 passes through the first push plate 2 to contact with the second push plate 3. The second push plate 3 is provided with a vent hole which is coaxial with the exhaust channel 7. The diameter of the vent hole of the second push plate 3 is the same as the diameter of the section of the exhaust channel 7. The first push plate 2 and the second push plate 3 are detachably connected.
The die cavity of the die body 1 is also provided with a deep hole sand core 6, and one end of the exhaust push rod 4 close to the deep hole sand core 6 is provided with an exhaust groove 5. The depth of the exhaust groove 5 is 1-1.5mm, and the width is 0.2-0.25 mm.
The utility model discloses when in actual use, the air in the mould body 1 passes through exhaust push rod 4 and discharges, and exhaust push rod 4 has the gaseous effect of ejecting psammitolite and discharge preparation psammitolite in-process. In the manufacturing process of the deep-hole sand core 6, air in a cavity of the die body 1 and compressed air brought in during sand shooting enter the exhaust channel 7 through the exhaust groove 5 at the air inlet end of the exhaust push rod 4 and are finally exhausted through the exhaust channel 7.
