Toilet bent pipe production die and manufacturing process thereof

Abstract

The invention relates to a toilet bent pipe production die and a manufacturing process thereof, and relates to the fields of toilets. The toilet bent pipe production die comprises a left die and a right die, wherein the left die comprises a drainage and exhaust inner layer and a waterproof and gas-proof layer which are arranged in a stacked mode from inside to outside, at least one ventilated cavity is formed in the drainage and exhaust inner layer or between the drainage and exhaust inner layer and the waterproof and gas-proof layer, at least one air hole is formed in the left die, and the air holes communicate with the at least one ventilated cavity. During the bent pipe demoulding, compressed air is injected through the air holes, air enters the ventilated cavity through the air holes,the waterproof and gas-proof layer ensures that gas does not circulate towards the back of the left die, all the gas circulates towards one side of the bent pipe through the drainage and exhaust innerlayer, so that a layer of large air dies is formed between the bent pipe and the left die, and the bent pipe and the left die are automatically separated out through the air dies. The technical problems that the toilet bent pipe is difficult to demould and the bent pipe or the toilet is prone to being damaged are solved.

Description

technical field [0001] The invention relates to the field of toilets, in particular to a mold for producing toilet elbows and a manufacturing process thereof. Background technique [0002] refer to Figure 7 to Figure 10 , when the toilet 3 is manufactured, high-pressure mud is injected into the grouting port, and the product is held for a certain period of time. Since the mold material is made of resin material with microporous characteristics, under a certain holding pressure, the moisture in the mold will flow from these micropores. The inner discharge forms a relatively dry mud embryo. At this time, the mold fixed on the machine starts to move and open the parts under the action of the oil cylinder. First, the upper mold 41 moves upward until it is separated from the product, and then the lower mold 42 moves upwards. Move down, and then the rear mold 43 moves backwards to separate from the product. Because there is an undercut inside the toilet sewage pipe, this position...
