The utility model discloses a mould structure for hot-press forming of bra cups by
silica gel cloth, which comprises a
processing table, a lower concave mould arranged at the top of the
processing table, a fixing frame fixedly connected to the top side of the
processing table, a first
hydraulic cylinder fixedly connected to the top of the fixing frame, and a lower end of the first
hydraulic cylinder connected with the top of an upper convex mould. Heaters are installed in the upper male die and the lower female die, the upper male die is arranged at the top of the lower female die, auxiliary material cloth is laid on the inner wall of the lower female die, a plurality of
pipe bodies are inserted into the lower female die, intercepting nets are arranged on the inner walls of the
pipe bodies, ejector rods are fixedly connected to the bottoms of the intercepting nets, the bottoms of the auxiliary material cloth are attached to the intercepting nets, and adsorption pipes are inserted into the
pipe bodies; the outer wall of the ejector rod is fixedly connected with a sealing ring, the bottom side of the
machining table is fixedly connected with a
vacuum pump, and one end of the adsorption pipe penetrates through the sealing ring to be connected with the
vacuum pump. The device can ensure the stability and flatness of the auxiliary material cloth in the
hot press molding process, and avoids the influence of wrinkles of the auxiliary material cloth on the finished product quality.
