Description

Technical Field

[0001] The utility model belongs to the technical field of toilet water tank manufacturing, and in particular relates to a toilet water tank forming press. Background Art

[0002] A toilet is a toilet appliance that receives feces and urine and flushes the feces away with water in a water tank. Users often use toilets in daily life. It is widely used in home life and some public places. During the production process of toilets and water tanks, ceramic slurry is injected into the injection mold of the toilet seat and the water tank, and the ceramic slurry is squeezed by a press to evenly fill the mold, and the ceramic slurry is cooled and formed in time, so that the toilet and the water tank are initially formed.

[0003] Existing, the cooling method of the injection mold is mainly to cool the injection mold by water cooling. Since the injection mold is divided into an upper mold and a lower mold, in order to ensure the consistency of the water cooling efficiency of the upper and lower molds, cooling cavities are usually opened in the upper mold and the lower mold, and corresponding pipes are respectively connected to the cooling cavities to form two sets of water cooling circulation systems. The increase in the number of water cooling circulation systems not only increases the cost but also increases the amount of water required for cooling, thereby reducing the utilization of water resources.
