If the inner concave is also arranged on the side wall of the local inner concave of the actual product, the outer side wall of the annular bulge can be correspondingly provided with a bulge. Therefore, a die cavity is formed after the die main body is in sleeve joint with the die inner container, and the die end cover is used for compression molding to realize EPS foam molding. The mould main part can be earlier separated with the mould inner bag in the drawing of patterns process after the shaping for high density EPS foam packaging body only is located inside the mould inner bag, and because the inner bag lateral wall and the annular bulge of mould inner bag are the thin wall form, it has certain deformability, so annular bulge and inner bag lateral wall can local deformation in the in-process of drawing of patterns, thereby be convenient for the drawing of patterns, especially be provided with the circumstances of local bulge on the bellied lateral wall of annular, also can realize the drawing of patterns, thereby realize the one shot forming of this type of product, greatly promote machining efficiency.

The die core hole is a stepped hole, one end of the stepped hole with a large aperture is positioned on the lower surface of the bottom wall of the inner container, and the lower end of the annular bulge is provided with a limiting ring matched with the stepped hole. The design of this structure, can be very big promotion the annular protruding in the downthehole firm in connection nature of mold core, it is detachable design moreover, greatly promotes the convenience of drawing of patterns in-process.

The lower surface of the bottom wall of the main body of the die is provided with a support frame, the support frame is connected with a plurality of rotary drums in a rotating mode, driven gears are arranged on the outer surfaces of the rotary drums, internal threads are arranged inside the rotary drums, screw rods are arranged in the rotary drums, a through hole is formed in the bottom wall of the main body of the die, corresponding to the screw holes, of the main body, the screw rods are fixedly connected with the bottom wall of the inner container of the die after penetrating through the through hole, a motor is arranged on the support frame on the side edge of each rotary drum, a driving gear is arranged on an output shaft of each motor, and the driving gear is in transmission connection with the driven gears in a matched mode. The design of this structure can be convenient for the separation and the cooperation of mould main part and mould inner bag more. Can carry out synchro control through the controller to all motors, utilize driving gear, driven gear to drive the rotary drum and rotate, rotate the in-process at the rotary drum, its inside screw rod owing to with mould main part between fix, so it only can carry out vertical movement in the rotary drum is inside, finally realizes the relative movement between mould main part and the mould inner bag, and separation at drawing of patterns in-process both is simple and convenient more, realizes automatic operation.

The utility model provides a high density EPS foam molding mould can utilize the separation of mould main part and mould inner bag to make inner bag lateral wall and annular lateral wall be thin wall column structure, have certain deformability, thereby greatly promote drawing of patterns effect and efficiency.
