Abstract

The utility model relates to the technical field of sand blowing heads, in particular to a sand blowing head of a hub die. Including the blowing sand head body, the blowing sand head body forms first air flue for hollow structure, and the rigid coupling has the clearance head on the blowing sand head body, and the clearance head includes along the clearance portion of first air flue outlet direction protrusion in the blowing sand head body, and the clearance portion can be arranged in the gas of blowing out in the first air flue. The cleaning part protrudes along the direction of the outlet of the first air passage and is directly arranged in the air flow axis area. Broken sand generated by the cleaning action is immediately wrapped and taken away by high-speed air flow, shielding of the air flow by the traditional lateral cleaning structure is avoided, synchronous scraping-sweeping operation is realized, and the problem of sand residue is solved.

Description

Sand blowing head of hub die Technical Field The utility model relates to the technical field of sand blowing heads, in particular to a sand blowing head of a hub die. Background The blowing heads typically employ a single air flow flushing arrangement, and improvements made in the prior art exist in configuring mechanical cleaning elements that are arranged in multiple loops around the air flow outlet. Such an arrangement would result in the cleaning element blocking the airflow path, impairing the airflow scouring effect, and there is still room for improvement. Disclosure of utility model The utility model provides a sand blowing head of a hub die, which aims to enable air flow to cover a cleaning component and enable air flow flushing and mechanical cleaning to be integrated. The above object is achieved by the following technical scheme: the utility model provides a wheel hub mould blowing sand head, includes the blowing sand head body, and the blowing sand head body forms first air flue for hollow structure, characterized by, the rigid coupling has the clearance head on the blowing sand head body, and the clearance head includes along the clearance portion of first air flue outlet direction protrusion in the blowing sand head body, and the clearance portion can be arranged in the gas of blowing out in the first air flue. The sand blowing head body comprises an outer cylinder, and an inner cylinder is fixedly connected to the lower portion of the outer cylinder. The sand blowing head body and the cleaning head are of an integrated structure. The sand blowing head body and the cleaning head are of detachable structures. The lower part of the inner wall of the outer cylinder is an expanded diameter section so as to form a shoulder, and an inner thread is arranged on the inner wall of the expanded diameter section; The cleaning head comprises an inner cylinder, an external thread is arranged on the upper portion of the outer wall of the inner cylinder, the external thread can be screwed into the internal thread, and the inner cylinder can be abutted against the shoulder. The cleaning head comprises a connecting part fixedly connected to the inner cylinder, and the cleaning part is fixedly connected to the connecting part. The cleaning part is a shovel blade. The cleaning part is a friction head. The bottom of the friction head forms a bulge. The connecting part is of a hollow structure, the cleaning part is a friction head, a brush or a scraping cylinder distributed at the lower part of the connecting part, and the connecting part and the cleaning part form a second air passage communicated with the first air passage. The sand blowing head of the hub die has the beneficial effects that: The cleaning part protrudes along the direction of the outlet of the first air passage and is directly arranged in the air flow axis area. Broken sand generated by the cleaning action is immediately wrapped and taken away by high-speed air flow, shielding of the air flow by the traditional lateral cleaning structure is avoided, synchronous scraping-sweeping operation is realized, and the problem of sand residue is solved.
