In the drawings

1. The device comprises an inner mold core, 2 parts of ejection bolts, 3 parts of an inner mold base, 4 parts of a mold cover, 5 parts of a support, 6 parts of a pedal, 7 parts of a connecting rod, 8 parts of a sliding rail, 9 parts of the ejection bolt base, 10 parts of a balance connecting rod, 11 parts of hinges, 12 parts of a reset piece and 13 parts of a cross rod.

Detailed Description

In the embodiment shown in fig. 1-3, a mold for manufacturing a gypsum mold shell, as shown in fig. 1, includes a support 5, an inner mold base 3 is fixedly disposed on the support 5, an inner mold core 1 is fixedly disposed on an upper end surface of the inner mold base 3, a plurality of ejecting bolts 2 are embedded on the inner mold base 3 at equal intervals around the inner mold core, mold covers 4 are hinged to four peripheral surfaces of the inner mold base 3 through hinges 11, corresponding buckles are disposed between adjacent mold covers 4, a sealing ring is disposed at a joint of the inner mold base 3 and the mold cover 4, a gypsum leakage is placed, the mold cover 4 is fixed by the buckles when being closed, and a distance between a top end surface of the mold cover 4 after closing the mold and a top end surface of the mold core 1 is equal to a distance between an inner side surface of the inner mold cover 4 and. As shown in fig. 2 and 3, the bottom end of the ejection bolt 2 is fixed in the ejection bolt seat 9, the ejection bolt seat 9 is a rectangular frame seat and is installed inside the internal mold die holder 3, the lower end surface of the ejection bolt seat 9 is fixedly connected with a cross rod 13, a balance connecting rod 10 is arranged in the middle of the cross rod 13, the central point of the balance connecting rod 10 is fixed on the cross rod 13, a reset piece 12 corresponding to the cross rod 13 is arranged at one end of the balance connecting rod 10, and the reset piece 12 is a magnet or a spring. The other end of the short rod is hinged with a short rod, the other end of the short rod is fixed on a cross rod 13, one end of a balance connecting rod 10, which is provided with a reset piece 12, is hinged with a connecting rod 7, the other end of the connecting rod 7 is connected with a pedal 6, and the two ends of the pedal 6 are limited in a slide rail 8. The slide rails 8 are fixed on the legs of the support 5. The ejection bolt seat 9 is made of light plastic or metal. The reset piece 12 is a magnet.

In specific implementation, before pouring, the mold cover 4 is closed and fixed through a buckle, the mixed gypsum material is poured into a cavity formed between the mold cover 4 and the inner mold core 1, because the distance between the top end surface of the mold cover 4 and the top end surface of the inner mold core 1 is equal to the distance between the inner side surface of the mold cover 4 and the outer side surface of the inner mold core 1, the upper surface of the gypsum is smoothed after the pouring is finished, the uniformity of the thickness of the gypsum mould shell can be ensured, after the gypsum reaches the demoulding condition, the buckle is released, the pedal 6 is stepped downwards by feet, the reset force of the reset piece arranged between the balance connecting rod 10 and the cross rod 13 is overcome (the reset piece overcomes the magnetic force when the reset piece is a magnet, and the resilience force of the spring when the reset piece is a spring), so that the magnet end of the balance connecting rod 10 rotates downwards, the other end of the balance connecting rod 10 rotates upwards to drive the short rod to move upwards, thereby driving the cross bar 13 to move upwards, and further driving the ejection bolt seat 9 to drive the ejection bolt 2 to eject the shuttering product upwards. When the shuttering product is ejected, the shuttering product is taken out by hand, the demoulding is finished, the pedal plate 6 is loosened, and the end 12 of the reset piece 12 of the balance connecting rod 10 is reset by magnetic force or resilience force, so that the next shuttering ejection is convenient.
