Description

Technical Field

[0001] This utility model relates to the field of sandblasting head technology, and more specifically to a sandblasting head for wheel hub molds. Background Technology

[0002] Sandblasting heads typically employ a single airflow scouring structure. Existing improvements include the inclusion of mechanical cleaning components, often arranged around the airflow outlet. This layout can obstruct the airflow path, weakening the scouring effect, and therefore leaves room for improvement. Utility Model Content

[0004] The above objectives are achieved through the following technical solutions:

[0005] A wheel hub mold sandblasting head includes a sandblasting head body, the sandblasting head body having a hollow structure forming a first air passage, characterized in that a cleaning head is fixedly connected to the sandblasting head body, the cleaning head including a cleaning part protruding from the sandblasting head body along the outlet direction of the first air passage, the cleaning part being able to be placed in the gas blown out from the first air passage.

[0006] The blower head body includes an outer cylinder, and an inner cylinder is fixedly connected to the lower part of the outer cylinder.

[0007] The blow head body and the cleaning head are integrated into one structure.

[0008] The blow head body and cleaning head are detachable.

[0009] The lower part of the inner wall of the outer cylinder is an enlarged section to form a shoulder, and an internal thread is provided on the inner wall of the enlarged section;

[0010] The cleaning head includes an inner cylinder, and the upper part of the outer wall of the inner cylinder is provided with an external thread, which can be screwed into the internal thread, and the inner cylinder can rest against the shoulder.

[0011] The cleaning head includes a connecting part fixed to the inner cylinder, and the cleaning part is fixed to the connecting part.

[0012] The cleaning part is a shovel.

[0013] The cleaning part is a friction head.

[0014] A protrusion is formed at the bottom of the friction head.

[0015] The connecting part is a hollow structure, and the cleaning part consists of friction heads, brushes or scrapers distributed at the bottom of the connecting part. The connecting part and the cleaning part form a second airway that communicates with the first airway.

[0016] The beneficial effects of this utility model's wheel hub mold sandblasting head are as follows:

[0017] The cleaning section protrudes along the outlet of the first air duct and is placed directly in the airflow axis area. The sand fragments generated by the cleaning action are immediately enveloped and carried away by the high-speed airflow, avoiding the airflow obstruction of traditional lateral cleaning structures, realizing simultaneous scraping and blowing operations, and solving the problem of sand residue.

[0027] A sandblasting head for a wheel hub mold includes a sandblasting head body and a cleaning head, both of which are detachable. The sandblasting head body includes an outer cylinder 1, the lower part of which is an enlarged section forming a shoulder 2, and an internal thread 3 is provided on the inner wall of the enlarged section.

[0028] The cleaning head includes an inner cylinder 4. An external thread 5 is provided on the upper part of the outer wall of the inner cylinder 4, which can be screwed into the internal thread 3, allowing the inner cylinder 4 to be threadedly connected to the inside of the outer cylinder 1, achieving a detachable connection between the two. A connecting part 6 is fixedly connected to the lower part of the inner wall of the inner cylinder 4, and a cleaning part protruding from the inner cylinder 4 is fixedly connected to the connecting part 6. The cleaning part is positioned on the axis of the gas flow channel formed by the sand-blowing head body, allowing the airflow entering the sand-blowing head body to flow through the cleaning part. When the cleaning part rubs against the sand on the hub, compared to the traditional cleaning structure surrounding the air outlet, it no longer obstructs the airflow, thus smoothly blowing the scraped sand away from the hub.

[0029] The cleaning head is designed to be detachable, allowing for the carrying of different cleaning parts.

[0030] Example 1 of the cleaning department:

[0031] The cleaning part is a scraper 7 made of plastic or metal, and one of the long sides of the bottom of the scraper 7 has a chamfered surface.

[0032] Example 2 of the cleaning department:

[0033] The cleaning part is a friction head 8 made of hard rubber, and the bottom of the friction head 8 is evenly distributed with protrusions.

[0034] Example 3 of the cleaning department:

[0035] Based on Embodiment 2, an air passage communicating with the outer cylinder 1 is formed at the center of the connecting part 6 and the friction head 8. This allows the airflow blown from the outer cylinder 1 to flow through the interior and exterior of the friction head 8, thus combining the new solution with the conventional solution.

[0036] Example 4 of the cleaning department:

[0037] The cleaning part is a brush 9, which, similar to Embodiment 3, has a ring-shaped bristle structure. The connecting part 6 is also ring-shaped, with protruding ribs that are fixed to the inner cylinder 4. The bristle structure is fixed to the lower part of the ring-shaped structure. The airflow from the outer cylinder 1 can flow through the inside and outside of the bristle structure, thus combining the new solution with the traditional solution. The brush 9 can be a plastic brush or a metal brush.

[0038] Example 5 of the cleaning department:

[0039] Based on Embodiment 1, the brush 9 is replaced with a cylindrical thin-walled scraper 10, and the brush 9 has rounded corners on both the inner and outer edges of its bottom. The scraper 10 is made of hard rubber or metal.

[0040] It is understandable that the outer cylinder 1 and the inner cylinder 4 can also be an integral structure, forming a complete wall-shaped rotating body, which can be applied to any of the above-mentioned cleaning section embodiments.

[0041] The design concept of the cleaning section in this application is a dual-purpose blowing and suction system, which can be used not only for blowing sand from wheel hub molds but also for suction, or for applications in daily life. Its use in conjunction with a vacuum cleaner should not be considered novel. Since the connection of the blowing head is not the inventive point of this application, the top of the outer cylinder 1 can be connected to the blow / suction gun head or the blow / suction nozzle of the blow / suction device using conventional methods such as insertion, sleeve, snap-fit, threaded connection, heat fusion, or adhesive bonding.
