As the global manufacturing industry continues to develop, technological innovation has become the key for enterprises to enhance their competitiveness.
Recently, Shandong Haomai Machinery Technology Co., Ltd. has made another important breakthrough in technological innovation.
Information from the State Intellectual Property Office shows that a patent applied by the company titled “A central mechanism of a vulcanizing machine and a vulcanizing machine” was authorized. The authorization announcement number is CN224360519U, and the authorization announcement date is June 16, 2026.
The patent application number is CN202521436971.0, the application date is July 10, 2025, and the inventors include Wang Jiandong, Dong Cheng, etc.
The patent classification number is B29C35/02, which belongs to the field of vulcanization equipment technology.
The patent abstract shows that the central mechanism of the vulcanizing machine of this utility model includes a ring seat, a center rod, and a capsule clamp. The center rod passes through the middle of the ring seat.
The top end of the first annular surface in the capsule clamp is radially inwardly connected with the first annular receiving surface, the top end of the second annular surface in the ring seat is radially inwardly connected with the second annular receiving surface, and an abutment protrusion is provided between the first annular receiving surface and the second annular receiving surface.
This design makes the first annular receiving surface of the capsule clamp and the second annular receiving surface of the ring seat come into contact through the abutting protrusion, thereby forming a gap between the two.
In this way, even after thermal expansion or internal pressure of the capsule under working conditions, the first annular receiving surface and the second annular receiving surface can still be separated by a certain distance, effectively avoiding the problem of difficulty in disassembly after locking due to contact extrusion.
This innovative design not only improves the efficiency of the vulcanizer, but also reduces maintenance costs, saving companies a lot of time and resources.
Haimai Technology was established on March 31, 1995 and listed on the Shenzhen Stock Exchange on June 28, 2011.
As a leading company in the global tire mold industry, its core business is tire molds, etc. It has significant technological and scale advantages and has great investment value.
