Description

Closestool return bend production mould

Technical Field

The utility model relates to a closestool field especially relates to a closestool return bend production mould.

Background

Referring to fig. 7 to 10, when the toilet 3 is manufactured, high-pressure slurry is injected into a slurry injection port, and after a product is kept and pressed for a certain time, because a resin material with micropore characteristic is adopted as a mold material, under a certain pressure keeping pressure, moisture in the mold can be discharged from micropores to form a relatively dry mud blank, at this time, the mold fixed on a machine table starts to move and open the mold of each component under the action of an oil cylinder, firstly, an upper mold 41 moves upwards until the product is separated, then, a lower mold 42 moves downwards, then, a rear mold 43 moves backwards to separate the product, because an inverted buckle exists in a toilet sewage discharge pipeline, the position is designed into a right sewage discharge pipe loose piece 45 and a left sewage discharge pipe loose piece 44, a bent pipe 31 (a sewage discharge pipeline) is formed between the left sewage discharge pipe loose piece and the right sewage discharge pipe loose piece, the right sewage discharge pipe loose piece 45, the left sewage discharge pipe loose piece 44 and the rear mold 43 are respectively adsorbed together through magnets arranged on the mold and the loose piece, when the rear die 43 moves backwards, when the demolding force is larger than the magnet suction force, the rear die is separated from the right sewage discharge pipe loose piece 45 and the left sewage discharge pipe loose piece 44, the right sewage discharge pipe loose piece and the left sewage discharge pipe loose piece are remained in the inner cavity of the toilet bowl at the moment (refer to fig. 9), then the blank supporting device moves forwards and upwards and is placed under the toilet bowl blank, at the moment, the blank supporting plate is ensured to be just slightly contacted with the lower end face of the toilet bowl in place, no gap or hard extrusion of the toilet bowl blank is needed, at the moment, the toilet bowl is buckled on a grouting machine by the right die and the left die, because the blank support is in place, the left die 46 and the right die 47 can be separated at the moment, the toilet bowl blank falls on the blank supporting plate, the blank supporting plate is moved to the blank placing station, the loose pieces in the blank supporting plate are manually taken out, and the production cycle of the toilet bowl blank product is completed. However, when the left sewage pipe loose piece and the right sewage pipe loose piece are demolded, because the negative pressure between the left sewage pipe loose piece and the right sewage pipe loose piece is large, and the space in the toilet seat at the sewage pipe is limited, the left sewage pipe loose piece and the right sewage pipe loose piece are difficult to demold easily, a product is often clamped on a mold, a field worker needs to spend more time to remove the mold from the product, the efficiency is influenced, if the force is too large for hard demolding, the left sewage pipe loose piece or the right sewage pipe loose piece is possibly collided with the toilet seat, the abrasion or the damage of the toilet seat is caused, even the sewage pipe is possibly deformed and damaged, and the quality and the attractiveness of the product are influenced.

Chinese patent application No.: 202020997128.0 discloses a closestool mould, including die block, top mould, right side limit mould and left side limit mould, the die block sets up the lower part at the closestool mould, right side limit mould and left side limit mould set up respectively the both sides of die block, the die block with right side limit mould and left side limit mould constitute the closed cavity, top mould detachably sets up the upper portion of closed cavity, the top mould includes two loose pieces groups that bilateral symmetry set up, loose piece group includes first loose piece and second loose piece, first loose piece and second loose piece are followed closed cavity's rear portion sets gradually to the front portion. The moulds on the two sides of the toilet sewage discharge pipeline need to be demoulded towards the two sides, and are not easy to demould due to limited space and large negative pressure, so that the forced demoulding easily causes the abrasion and the damage of the toilet and the deformation and the damage of the sewage discharge pipe.
