[0002] The existing micro-bubble generator utilizes the flow rate difference between the water flow in and out of the dissolved air chamber and the height difference between the inlet and the outlet to form a water seal at the outlet, so that the air pressure in the dissolved air chamber is gradually increased to form a high-pressure chamber, thereby increasing the dissolved air pressure. The amount of dissolved air in the cavity, while the diameter of the inner hole of the nozzle of the microbubble generator is very small and the height of the inner hole is much larger than the diameter of the inner hole, the conventional mold cannot meet the forming requirements of the inner hole of the nozzle

The invention discloses a preparation apparatus and a preparation method for a cavitation spray head. The preparation apparatus comprises a first mold assembly; the first mold assembly comprises a first rear mold and a first front mold; a first molding cavity is defined between the first rear mold and the first front mold; one of the first rear mold and the first front mold is provided with a first protrusion, and the other one comprises a first mold body, a first insert pin and a first insert pin protection member, wherein the end of the first insert pin extending into the first mold body abuts against the first protrusion; the first insert pin and the first protrusion are used for molding one portion of a venturi channel of a first pipe fitting; and the first insert pin protection memberis sleeved on the outer side of the first insert pin. The preparation apparatus for the cavitation spray head according to the embodiment of the invention can effectively prevent the damage of the first insert pin during molding of the first pipe fitting, so that the reliability and stability of the first mold assembly are improved, the production abnormality is reduced, the size precision requirement of the venturi channel is guaranteed, and the pass percent of the cavitation spray head is increased.
Description
technical field [0001] The invention relates to the field of molds, in particular to a preparation device and a preparation method of a cavitation nozzle. Background technique [0002] The existing micro-bubble generator utilizes the flow rate difference between the water flow in and out of the dissolved air chamber and the height difference between the inlet and the outlet to form a water seal at the outlet, so that the air pressure in the dissolved air chamber is gradually increased to form a high-pressure chamber, thereby increasing the dissolved air pressure. The amount of dissolved air in the cavity, while the diameter of the inner hole of the nozzle of the microbubble generator is very small and the height of the inner hole is much larger than the diameter of the inner hole, the conventional mold cannot meet the forming requirements of the inner hole of the nozzle. Contents of the invention [0003] The present invention aims to solve at least one of the technical pr...
