In order to achieve the above purpose, the utility model provides a back seat mold core-pulling exhaust structure, which comprises a mold, wherein the mold comprises a mold B surface, the back seat mold core-pulling exhaust structure further comprises an insert and an air cylinder, the insert comprises an insert base and an insert body which are integrally formed, the insert body is in a round table shape, the insert base is cylindrical, the insert base is connected to a small table surface end of the insert body, an exhaust hole which communicates a mold cavity with the outside of the mold is arranged on the mold B surface, the shape of the exhaust hole is consistent with that of the insert, the insert is movably plugged at the exhaust hole, the large table surface end of the insert body faces one side of the mold cavity, a threaded counter bore is arranged on one side, close to the outside of the mold, of the insert, the air cylinder is fixed on the surface of the mold, a push rod of the air cylinder is in threaded connection with the threaded counter bore, and the extending direction of the push rod is consistent with the direction of the exhaust hole, and the push rod can drive the insert to move into the mold cavity, so that the exhaust hole is opened.
In the scheme, the method comprises the following steps: the cylinder is equipped with the cylinder base, be equipped with the cylinder mount pad on the mould, cylinder mount pad both sides of exhaust hole, cylinder base passes through the bolt fastening with the cylinder mount pad, simple to operate.
In the scheme, the method comprises the following steps: the diameter of the insert base is smaller than that of the small table face end of the insert body, and the insert base is provided with steps, so that the insert is convenient to close.
In the scheme, the method comprises the following steps: the diameter of the smallest part of the exhaust hole is 70mm-150mm, and compared with the diameter of the exhaust pin, the diameter of the core-pulling exhaust is far greater than the diameter of the exhaust pin, so that the exhaust effect can be effectively improved, and the exhaust tolerance is increased.
The beneficial effects of the utility model are as follows: when the mold is poured, the insert is movably plugged at the exhaust hole, so that pouring liquid can be prevented from flowing outwards, and after pouring is finished, the ejector rod can drive the insert to move into the cavity to squeeze and foam, so that the exhaust hole is opened, and the exhaust function is realized; in a word, the utility model has simple structure and convenient operation, effectively reduces the exhaust cost of the foaming mould with thickened backseat, obviously improves the problem of poor exhaust of the mould, and is convenient for workers to clean normally in a cleaning mode according to the cleaning mode of the exhaust pin.
